What is Vision Loss?

Blindness is the absence or loss of vision entirely. As is well known, the vision process consists of light entering the eyes, travelling through the anterior segment to the retina, being sent to the brain via the optic nerve or optic nerve, and creating sense in the brain. Blindness develops when any of these organs are damaged or lacking. Peripheral vision loss disease can be caused by eye conditions and other health conditions. It is important to seek treatment right away, as it is often impossible to restore lost vision. Getting treatment early can help prevent further  peripheral vision loss or central vision loss.

 Problems with the visual pathways may develop later in life as a result of trauma or a number of disorders, or they may be present at birth. Legal blindness is defined as less than 10 percent vision or a field of vision that is narrower than 20 degrees in the uncorrected eye of a person with normal vision.

Can cataracts be prevented?

It is estimated that at least 10 million individuals worldwide are blind due to avoidable causes. When certain diseases begin to restrict the visual field by applying pressure to the optic nerve, it is nearly impossible for the patient to recognize this on his or her own. Vision loss can be prevented if patients are diagnosed early through routine eye exams.

Generally speaking, there is no treatment for trachoma, leprosy, diabetes (diabetes), glaucoma, cataract, retinal detachment, or congenital (congenital) blindness.

Can eye color change surgery cause vision loss?

Yes, this is possible. Especially surgery to change eye color procedures (keratopigmentation and iris implant surgery) can cause permanent vision loss. In addition, since we invented the laser eye color changing process, the risk of permanent vision loss is quite high in amateur and poor-quality clinics opened in indistinct places. This is why you need an experienced and reliable doctor to change your eye color.

Problems that the Visually Impaired Face-vision loss prepheral or central

Currently, it is evident that visually impaired individuals face more obstacles than those who can see. As a result of the inability to provide them with suitable employment opportunities, they face numerous obstacles in their daily lives. Nevertheless, it is everyone’s right to enjoy fundamental rights such as education, training, and health, and there should be no barriers to their exercise.

Difficulties confronting the visually impaired

  • No audible warning system at traffic lights * Merchants setting up stalls on sidewalks * Parking of cars on sidewalks * No audible warning system prior to bus stops * Occupying the yellow line used by the visually impaired to follow with vehicles or stalls
  • Trees, electricity poles, and traffic signs are not planted in a specific order. * Mushrooms designed to prevent cars from driving on the sidewalks are at a height at which visually impaired individuals can trip and fall.
  • Pavement surfaces and roads are not flat enough to allow water to collect. * Traffic signs are at a height where visually impaired people can hit them.
  • Tree-trimming so that visually impaired individuals can hit lower branches

ADVICE REGARDING EYE HEALTH * Do not rub your eyes.

Stop immediately if you have such a routine. Keratoconus is caused by eye rubbing, which appears harmless.

  • Consider hygiene important.
  • Eye allergy, also known as conjunctivitis, is transmitted through the use of shared towels, unclean hands, and makeup products.
  • Examined frequently.
  • In addition to eye diseases, a routine eye exam allows for the early detection of a number of other diseases, including diabetes and hypertension. A yearly eye exam is recommended.

*Be mindful of these indicators
Even temporary vision loss, double vision, pale colors, and flashes of light necessitate immediate medical intervention. Consult an ophthalmologist immediately if these symptoms occur.

Glaucoma is the most treatable disease that causes blindness worldwide. So what is the treatment?

Glaucoma, also known as elevated eye pressure, is a disease that is asymptomatic and known for its stealth. Nevertheless, it can be detected through measurements taken during routine eye examinations. If it is not diagnosed and treated in a timely manner, it can lead to vision loss and eventual blindness.

Glaucoma, commonly referred to as glaucoma, can occur at any age. Simply put, it is the damage to the optic nerve caused by an increase in intraocular pressure. The disease has no symptoms, but it can be detected through measurements taken during routine eye exams. Because of this, it is referred to as a deceptive eye disease.

leading cause of blindness

Glaucoma is the most treatable disease that causes blindness worldwide. In glaucoma, an early diagnosis is essential. Because glaucoma is an eye disease that can be treated in its early stages but cannot be cured if it is left untreated for too long. This condition, which proceeds insidiously, can only be diagnosed in 90% of cases by an ophthalmologist without the patient’s complaint. Due to their complaints, the remaining 10% of glaucoma patients do not seek treatment from an ophthalmologist.

Risk Groups

After the age of 45, those with a family history of glaucoma, diabetics, myopic patients, hypertensive patients who are not regularly treated, and those receiving long-term cortisone treatment are at an increased risk for developing glaucoma.

Normal intraocular pressure ranges from 10 to 20 mm Hg in a healthy individual. However, not all patients with intraocular pressures exceeding 20 may have glaucoma. For instance, we refer to patients with ocular hypertension if their intraocular pressure is greater than 20 mm Hg. However, the optic nerve is asymptomatic. It should be noted, however, that 25% of ocular hypertension patients may develop glaucoma in the future. Therefore, every six months, these patients should contact an ophthalmologist.

Treatment and Diagnosis

Due to technological advancements, glaucoma may now be diagnosed with relative ease. Measuring intraocular pressure during annual eye exams is the most efficient method for diagnosing intraocular pressure. Other diagnostic techniques consist of fundus examination, computer vision field, NFA, and TopSS.

Treatment is determined by the intraocular pressure at the time of disease diagnosis and the extent of optic nerve damage. The treatment’s primary objective is to maintain normal intraocular pressure while protecting the optic nerve and, consequently, the degree of vision. According to the stage of glaucoma, medical treatment, laser treatment, and surgical treatment should be administered in that order.

Does eye color change cause vision loss?

Undoubtedly, like any medical procedure, you should choose your doctor well. moreover, this is not enough, the type and validity of the method used ensures that you do not experience vision loss.

  1. Keratopigmentation surgery has so many side effects and complications that it can cause permanent vision loss.
  2. Iris implant surgery: There is a 99.9% chance that you will experience vision loss and even go blind.
  3. Laser eye color change: If it is not done by a professional clinic and doctor, you are likely to experience permanent vision loss. It is the safest among eye color changing procedures; for this, you need to get the Lumineyes method and choose an experienced doctor.

Lumineyes Xtra provides you with all kinds of security for eye color change safely and without risk. And of course, we remind you of the unique experience and abilities of Dr. Mustafa Mete.

The health of our eyes, one of our important sense organs, is of utmost importance.

Regular eye exams should be conducted at all ages. Against every hazard, the necessary precautions must be taken. Vision and eye health must be evaluated periodically. Because you may be unaware of having an eye condition. Even if it is inherited, it can occur at a mature age. We can see this in some instances. A sudden onset of an eye problem may occur even if the individual has been free of eye problems for many years. There may be multiple causes for this. Although genetics are largely effective, environmental factors also play a significant role.

Even stress can lead to deterioration of the eyes. In actuality, it is clear from these stories that the most important thing is to prioritize our health. In the same way that stress not only affects the eyes but also causes numerous problems in our daily lives, we must prioritize our health, including our spiritual and psychological well-being. According to the World Health Organization, this describes health. According to the World Health Organization, health encompasses a person’s physical, mental, and social wellbeing. Consequently, how can we protect our overall health from stress, etc.?

Similarly, for our eye health, we must be aware of and implement all of these precautions. Eye issues may not always be benign issues. In the event of health issues, even blindness in the eyes may result from a variety of causes. Numerous eye diseases can result in blindness. If timely diagnosis and treatment are administered, this can be avoided.

Blindness can be congenital or acquired due to an illness or an accident. Blindness is the loss of vision, whether partial or total. The inability to distinguish between darkness and light is synonymous with total blindness. Vision loss in one or both eyes constitutes partial blindness.

Peripheral vision loss

Peripheral vision loss can be caused by a number of underlying medical issues. Migraines induce transient peripheral vision loss, however other disorders might lead to persistent PVL. PVL can develop gradually, affecting only your side vision at first.

Some of the reasons of peripheral vision loss are as follows:

glaucoma

What exactly is glaucoma? This eye ailment creates pressure in the eye as a result of fluid accumulation and has a direct impact on peripheral vision. If left untreated, it can damage the optic nerve and result in permanent blindness. in Lumineyes clinic we use laser to treat glaucoma.

Pigmentosa Retinitis

As your retina deteriorates, this genetic disorder will progressively cause peripheral vision loss, as well as night vision and potentially central vision. There is no treatment for this rare disorder, but if detected early, eyesight loss can be planned for.

scotoma

What exactly is scotoma? If your retina is injured, you may acquire a blind patch in your eyesight known as a scotoma. Other eye disorders, such as glaucoma, inflammation, and macular degeneration, can cause this.

Stroke

What exactly is a stroke? A stroke might result in irreversible visual loss in one eye. This is because a stroke affects only one side of the brain. Because your eyes are still operating, this is a neurological sort of vision loss. However, your brain is incapable of processing what you perceive. A scotoma can also be caused by a stroke.

Diabetes-Related Retinopathy

What exactly is diabetic retinopathy? This issue develops when you have diabetes and your retina is damaged as a result of excessive blood sugar, which inflames or limits the blood vessels in your eye.

Migraine

What exactly is a migraine? Migraine is a form of headache that can cause alterations in eyesight. According to the Migraine Foundation, between 25 and 30 percent of migraine sufferers report visual abnormalities during migraine with an aura. This may involve momentary loss of peripheral vision.

Is it temporary or permanent?

Depending on the cause of the vision loss, peripheral vision loss might be transient or permanent.

The following factors can contribute to persistent PVL:

glaucoma retinitis pigmentosa scotoma diabetic retinopathy

Temporary peripheral vision loss can occur as a result of:

migraine

Narrowing of the Visual Field (Glaucoma Symptom)

Visual Field refers to the total field that any eye can view when looking at a fixed place. Normal eyes have a visual field width of 60o at the nose (nasal), 70o below, 50o above, and 90o at the ear side (temporal). As there is no obstruction on the outer side of the eye, the ear-side of the visual field is the widest. Actually, our eyes are a reflection of our total health. Numerous illnesses of the brain, cerebral arteries, and nerves can manifest in the eye. Visual field constriction is an insidious ailment. The cause may be a variety of disorders. Before the progression of the underlying condition, patients may be unaware of the visual field narrowing.

Glaucoma, sometimes known as glaucoma, can present as a complaint of the visual field becoming narrower. Glaucoma is a condition characterized by visual nerve degeneration caused by intraocular pressure. As a result of the slow loss of the fibers composing the optic nerve caused by pressure, the vision field begins to contract.
Due to irreversible nerve fiber injury, substantial vision field loss and even blindness are inevitable in the absence of appropriate diagnosis and treatment. Glaucoma is a significant public health issue and the second leading cause of blindness in affluent nations. Glaucoma affects around one in fifty adults over the age of 35.

The most common causes of sudden vision loss

WHAT IS SUDDEN LOSS OF VISION?

Sudden vision loss refers to visual loss that happens within seconds, minutes, or days. Vision may become blurry, vanish entirely, or be disturbed by floaters, which are flashing lights or dots in the visual field. A portion or the entirety of the field of view may be impaired. The majority of the time, sudden vision loss is painless, however eye discomfort, redness, and headaches may accompany vision loss.

Even if only a portion of the visual field is affected or the condition resolves on its own, any rapid alteration in the visual field is potentially hazardous.

Visual loss is a medical emergency, and anybody experiencing vision loss should seek immediate medical assistance. The assessment includes an eye exam and a neurological exam to test the eyes’ and brain’s functionality. In addition to blood tests and brain imaging scans, the first examination may also include blood tests and brain imaging scans. Vision loss is examined and tested for both particular eye diseases and broader medical issues that may be associated.

Eye drops, drugs, or surgery can be used to alleviate vision loss caused by eye-related issues.

If inflammation is the source of visual loss, medicines can be administered. If visual loss is caused by the abrupt occlusion of a blood artery, the goal of therapy is to restore blood flow as quickly as feasible. Depending on the underlying reason, prompt therapy can decrease or reverse visual loss.

Problems at any step along the visual pathway from the eyes to the brain might result in vision loss. When light enters the eye, it is transformed into electrical impulses that are then processed by the brain. Light enters the eye through a hole called the pupil, and cells in the retina at the back of the eye turn it into electrical impulses. The optic nerves carry these impulses from the eyes to the brain. The occipital lobes of the brain process visual information. Vision loss can be caused at any point along this visual pathway if it is compromised.

CORTICAL CATARACT

Cataracts, a yellowing or bleaching of the lens of the eye, are prevalent among older individuals. Usually, cataract-related vision loss occurs gradually, but certain forms of cataracts can have an immediate impact on vision. Outside the lens, cortical cataract develops and spreads across the lens. In certain instances, when they grow in the center of the lens, they might result in an abrupt loss of eyesight within a few weeks. Cataracts can cause glare, trouble reading in low light, and a general decline in close and distant vision that cannot be remedied by glasses. He can do surgery in the treatment of cataracts.

WET MACULAR DEGENERATION

Retina, or the rear wall of the inner eye, receives light and turns it into electrical impulses that are sent to the brain and perceived as vision. At its core lies the macula, the region of the retina that processes high-contrast vision, allowing humans to engage in daily activities like as reading and driving.

In macular degeneration (yellow spot disease), the photoreceptors of the macula that process vision begin to shrink and perish as drusen deposits accumulate under the retina and block the supply of nutrients to the weak receptors.

The majority of instances of macular degeneration are gradual, age-related, and develop slowly. It is referred to as dry macular degeneration. In 10% of instances, however, the disease progresses to wet macular degeneration, when fluid from blood vessels attempting to replace nutrition spills into the retina.

This fluid immediately and significantly impairs eyesight. It also causes vision impairment, particularly with pictures that are wavy. If fluid is not treated, it can result in extensive scarring and irreparable vision loss.

When macular degeneration is detected, an Amsler grid is provided to determine whether the disease is dry or wet. Each eye focuses on the middle of the grid. If the lines are wavy, moist yellow spot disease may be present.

RETINAL REPAIR OR DETACHMENT

The retina is composed of extremely thin layers. Retinal tears and retinal detachment are frequently connected with a disease known as posterior vitreous detachment, which is a natural consequence of aging. In this condition, the vitreous gel that fills and shapes the eye pulls away from the retina.

Posterior vitreous detachment affects the majority of individuals over the age of 50. This pull can produce a hole in the vitreous retina or tear the retina in a limited number of individuals. Injuries can also result in tears or ruptures. Symptoms include flashes of light, several new eye floaters that may resemble snowflakes falling, and a black curtain dropping over the eyes.

A minor retinal tear or detachment can lead to irreversible vision loss if not discovered early. Visit an eye doctor immediately if you have any of these symptoms.

A retinal tear or detachment is treated based on its severity. If there is a tear, your doctor may use laser surgery to reattach the retina. Your doctor may inject an air bubble into your eye to press the retina back into place and then use a laser to repair the tear if you have a tear with a slight break. If you have a greater separation, your doctor may propose more comprehensive surgery.

HUGE CELL ARTERITIS

Inflammation of the arteries surrounding the scalp is a typical occurrence in the elderly with giant cell arteritis, a disorder characterized by giant cell arteritis. (Also known as temporal arteritis.) Most affected is the temporal artery on the side of the head, causing headaches and soreness. Additionally, the ophthalmic artery and tiny arteries that nourish the optic nerve, which links the eye to the brain, may be impacted. When these arteries become inflamed, blood supply to the optic nerve is obstructed, resulting in immediate, permanent vision loss.

If you encounter this sort of visual loss, you must consult an eye doctor near you immediately. If giant cell arteritis is not identified and treated, it can result in total blindness in both eyes and damage to the veins that supply the brain. After a temporal artery biopsy confirms a diagnosis of giant cell arteritis, your doctor will often begin therapy promptly to protect your remaining vision.

The sooner a physician is consulted, the greater the likelihood of recovery. For instance, when a doctor is contacted for a transient headache, vision loss in both eyes can be averted. However, most patients see the doctor with vision loss in one eye, and thus the treatment focuses on preserving vision in the other eye.

CENTRAL RETINAL ARTERY OBSTRUCTION

Occlusion of the central retinal artery causes paralysis of the eye. Occlusion of the central retinal artery produces transient visual loss that seldom recovers.

The central retinal artery nourishes the optic nerve and retina with blood. In central retinal artery occlusion, the central retinal artery is blocked by an embolus (plaque from a vein, a platelet aggregation, or anything floating in the blood).

When hospitalized with this disease, patients are frequently referred immediately to the emergency department for treatment. Even with a single eye stroke, the risk of cerebral palsy is significant. Because brain vessels are likely to be impacted in the future, but not simultaneously.

People with central retinal artery blockage are more likely to have plaque in the carotid arteries of the neck or other risk factors for stroke, such as atrial fibrillation, irregular pulse, or a blood clotting condition.

Your doctor may attempt to restore vision loss by dramatically decreasing eye pressure, massaging the eye, or applying a laser to the plaque, depending on the severity of the disease. Unfortunately, there is scant evidence to support these therapies, and eyesight loss is frequently irreversible.

MIGRAINE

Other than the eye, sudden peripheral vision loss or central vision loss may have relatively minor and transitory causes. Multiple conditions are capable of causing rapid, temporary visual loss. Migraines are the leading cause of transient visual impairment. Migraines can result in blind patches or the sensation of seeing flashing lights. Migraine can cause rapid, momentary loss of vision in both eyes.

ARE YOU AT RISK OF Blindness?

There are elements that might increase a person’s susceptibility to blindness. Here are some of the risk factors for blindness:

– Background of eye surgery

– inadequate hygiene,

– Diabetes,

– Any cardiovascular disease,

– stroke,

– Certain eye disorders,

– A history of blindness in the

– Preterm infant (premature birth),

– older ages,

– prenatal deficits,

– Cigaret,

– Exposure to hazardous substances

Regular eye examinations help prevent the onset of blindness. Periodic eye exams help guarantee that you receive prompt treatment for any eye issues or abrupt conditions. This can help prevent vision loss. When you have been diagnosed with a certain type of eye illness, it is crucial to adhere to your eye doctor’s treatment guidelines. If you suspect that you are experiencing blindness or visual loss, you should contact an ophthalmologist immediately to receive appropriate treatment.

You should get your children’s eyes examined at six months and three years of age.

Once kids reach the age of six, you should get their eyes examined annually to ensure they remain healthy and show no indications of blindness. However, if you suspect you have eye disease or any other visual issues, it’s advisable to see an ophthalmologist as soon as possible. Waiting for the eye condition to resolve itself is never a solution and might result in irreversible vision loss in youngsters.

Some types of blindness are brought on by hunger or malnutrition. In such circumstances, blindness can be avoided by maintaining a healthy diet. Vision loss can be prevented by using the proper eye protection. As long as you observe the measures prescribed by your eye doctor, blindness can be avoided if an eye condition is diagnosed and treated early. When glaucoma is discovered early, for instance, effective and timely interventions can be performed to avert blindness.

If you have diabetes, you should prioritize consuming low-sugar meals. Managing your diabetes and regulating your blood sugar levels, which may be caused by diabetes, are essential.
This will aid in preventing blindness. Exercise and keeping a healthy weight are also beneficial for your eyes and general health. You should prioritize healthy behaviors and avoid anything that may enhance your future risk of blindness. Even if certain things are beyond your control, you should concentrate on what you can influence.

It is vital to note that, on average, blindness develops with age. Although there are no preventative interventions available for these causes of blindness, research is ongoing.
