Retinal Detachment: Causes, Symptoms & Laser Surgery

A retinal detachment is a medical emergency. Dr. Mustafa Mete provides advanced diagnostic imaging, barrier laser retinopexy, and microsurgical intervention to preserve and restore vision.

A retinal detachment is not merely an ocular problem; it is a time-critical surgical emergency. When the neurosensory retina separates from its underlying vascular bed, every passing hour deprives photoreceptor cells of vital oxygen and metabolic nourishment. Without immediate surgical intervention, macular ischemia rapidly leads to permanent, irreversible central blindness.

What is Retinal Detachment?

The retina functions as the photographic film of the eye—a delicate, ten-layer light-sensitive tissue lining the inner back wall of the globe. In a healthy eye, the neurosensory retina remains closely attached to the Retinal Pigment Epithelium (RPE) and choroid, which supply it with oxygen and nutrients.

Retinal detachment occurs when the neurosensory layer peels away from the RPE. Depending on the mechanical etiology, retinal detachments are clinically classified into three distinct categories:

• Rhegmatogenous Retinal Detachment (RRD): The most common form (derived from the Greek rhegma, meaning rupture). A tear or full-thickness hole develops in the retina, allowing liquefied vitreous gel to pass under the sensory layer and dissect it away from the RPE.
• Tractional Retinal Detachment (TRD): Fibrovascular scar tissue—frequently seen in advanced proliferative diabetic retinopathy or sickle cell retinopathy—contracts and mechanically pulls the retina off the back wall without a primary break.
• Exudative (Serous) Retinal Detachment: Fluid accumulates under the retina without any tear or traction, secondary to intraocular inflammation (such as Vogt-Koyanagi-Harada syndrome), malignant hypertension, or choroidal tumors.

The Transition: From Retinal Tear to Full Detachment

Most rhegmatogenous detachments begin as an uncomplicated retinal tear or flap (horseshoe tear). As we age, the vitreous gel naturally undergoes liquefaction (synchysis) and shrinkage (syneresis), culminating in a Posterior Vitreous Detachment (PVD).

In eyes with strong vitreoretinal adhesions or pre-existing weak zones—such as peripheral lattice degeneration—the detaching vitreous pulls on the thin retinal tissue instead of separating cleanly. If this mechanical tug creates a tear, liquid vitreous is pumped under the retina with every ocular saccade, transforming a microscopic tear into a full detachment within hours or days.

Advanced Diagnostic Protocol at MyLumineyes

Accurate diagnosis dictates surgical success. In our Istanbul center, emergency vitreoretinal evaluations include:

• Scleral Depressed Indirect Ophthalmoscopy: The clinical gold standard. Allows meticulous visualization of the entire peripheral retina up to the ora serrata to detect small, anterior tears.
• High-Resolution B-Scan Ultrasonography: Indispensable when media opacity (such as dense vitreous hemorrhage or mature cataracts) prevents optical visualization of the fundus. It confirms whether the retina is flat, detached, or folded.
• Swept-Source Optical Coherence Tomography (SS-OCT): Maps the microstructural layers of the fovea, identifying subclinical subretinal fluid and assessing photoreceptor integrity before and after surgery.

Surgical Interventions: Repairing Retinal Breaks and Detachments

Treatment strategy is determined by the configuration of the tear, the extent of subretinal fluid, lens status (phakic vs. pseudophakic), and whether the macula is still attached (macula-on vs. macula-off).

1. Laser Photocoagulation (Argon Laser Retinopexy)

When caught early—while the tear is still flat or surrounded by minimal localized fluid—retinal detachment can be prevented entirely without intraocular surgery.

Using green or argon wavelength lasers, targeted energy spots are applied in 2 to 3 contiguous rows surrounding the retinal break. The laser induces controlled thermal necrosis of the outer retinal layers and RPE. Over the subsequent 10 to 14 days, this controlled burn forms a permanent chorioretinal scar ("laser weld") that prevents fluid from migrating into the subretinal space. To understand how specialized light interactions operate across ocular tissues, explore our clinical research on ophthalmic lasers and tissue physics.

2. Cryopexy (Transscleral Freezing)

If a tear is located in the extreme anterior periphery, or if vitreous hemorrhage obscures laser transmission, transscleral cryopexy is applied. A freezing probe placed on the outer surface of the sclera creates a full-thickness freezing adhesion that achieves the same scarring barrier as photocoagulation.

3. Pars Plana Vitrectomy (PPV)

For established retinal detachments, modern micro-incisional vitrectomy (23G, 25G, or 27G) represents the primary gold standard worldwide.

• Core & Peripheral Vitrectomy: Micro-trocars are placed through the pars plana. The tractional vitreous gel pulling on the retina is completely excised using high-speed vitreous cutters (up to 10,000 cuts/min).
• Drainage of Subretinal Fluid: Fluid beneath the detached retina is aspirated through the original tear, allowing the neurosensory layer to settle back smoothly against the RPE.
• Endolaser Photocoagulation: An intraocular laser probe applies precise barrier burns directly around all identified breaks inside the eye.
• Endotamponade (Gas vs. Silicone Oil): To keep the retina pressed against the eye wall while the laser scars mature, the vitreous cavity is filled with a temporary tamponade:
  • Expandable Gases (SF6, C2F6, C3F8): Naturally absorbed by the body over 2 to 8 weeks. No secondary surgery is needed to remove them.
  • Medical Silicone Oil: Used in complex cases, giant retinal tears, or severe proliferative vitreoretinopathy (PVR). Silicone oil remains in the eye indefinitely and requires a secondary minor procedure for removal once the retina is permanently healed.

4. Scleral Buckling

In younger, phakic patients with clear natural lenses and uncomplicated inferior detachments, scleral buckling remains an exceptional technique. A flexible silicone band or sponge is sutured onto the outer scleral wall, indenting the eye wall inward toward the tear. This counteracts vitreous traction without entering the vitreous chamber, preserving the natural crystalline lens and reducing cataract acceleration.
