Retinal Detachment

Retinal detachment (RD) is a sight-threatening ophthalmic emergency occurring when the neurosensory retina separates from the underlying retinal pigment epithelium (RPE). This separation disrupts the blood supply and nutrient exchange, leading to rapid photoreceptor damage and permanent vision loss if not surgically repaired.

RD is primarily caused by fluid accumulation in the subretinal space. It is categorized by mechanism: Rhegmatogenous (caused by a retinal break), Tractional (caused by fibrotic bands pulling the retina), or Exudative (caused by fluid leakage from inflammatory or vascular conditions).

In rhegmatogenous RD, liquefied vitreous humor passes through a retinal tear, stripping the retina from the RPE. In tractional RD, fibrovascular membranes exert mechanical force on the retina. In exudative RD, the integrity of the blood-retinal barrier is compromised, allowing fluid to accumulate beneath the retina without a physical break.

Incidence is approximately 1 in 10,000 annually. Peak onset occurs between age 50 and

1. It is more prevalent in men and individuals with high myopia.

• High myopia (axial length >25mm)
• Previous ocular surgery (e.g., cataract extraction)
• Ocular trauma
• Lattice degeneration
• Family history
• Pseudophakia/Aphakia

A. Early Symptoms: Photopsia (flashes of light), sudden increase in floaters.
B. Common Symptoms: Blurred vision, peripheral visual field loss.
C. Advanced Symptoms: "Curtain" or "shadow" encroaching over the visual field.
D. Emergency Symptoms: Sudden loss of central vision (macular involvement).

Indirect ophthalmoscopy reveals a wavy, elevated retina, loss of the underlying choroidal pattern, and potentially identifiable retinal breaks or tractional bands.

A. Clinical Assessment: Slit-lamp biomicroscopy, dilated fundus exam.
B. Laboratory Testing: Generally not required for diagnosis.
C. Imaging Studies: B-scan ocular ultrasonography.
D. Functional Tests: Visual field testing (if indicated).
E. Biopsy Findings: N/A.
F. Genetic Testing: Rare (for syndromic cases like Stickler syndrome).
G. Differential Diagnosis: Retinoschisis, choroidal detachment, uveal effusion.

None specific for routine diagnosis.

B-scan Ultrasonography: Essential when fundus visualization is obscured by cataract or vitreous hemorrhage. Findings include a mobile, reflective membrane in the vitreous cavity.

Degenerative retinoschisis (static and dome-shaped vs. mobile RD), posterior vitreous detachment, and choroidal hemangioma.

Proliferative vitreoretinopathy (PVR), secondary glaucoma, hypotony, and permanent legal blindness.

A. Lifestyle Modifications: Avoid heavy lifting, minimize physical exertion.
B. Preventive Measures: Prophylactic laser retinopexy for high-risk tears.
C. Medical Treatment: None curative.
D. Surgical Treatment: Pneumatic retinopexy, scleral buckling, pars plana vitrectomy.
E. Interventional Procedures: Cryotherapy.
F. Rehabilitation: Post-operative positioning (gas tamponade requirements).
G. Emergency Management: Immediate surgical referral.

Good if the macula remains attached; poor if macular detachment occurs for >24-48 hours prior to repair.

Routine dilated exams for high-risk patients; prompt evaluation of new-onset flashes/floaters.
