Question

A patient presented to the eye OPD after 3 years of cataract surgery. Slit lamp finding was given. What is the likely diagnosis?

• A. PCO
• B. Bullous keratopathy
• C. Phakic glaucoma
• D. Lens subluxation

Hint:

PCO is a common complication after cataract surgery and can often be treated with a YAG laser capsulotomy to restore vision.

Answer 1

The Correct Option is A

The question presents a scenario where a patient returns for an eye examination three years after undergoing cataract surgery. Based on the time elapsed and the clinical finding described (which is observed using a slit lamp), we need to determine the probable diagnosis from the given options.

Post cataract surgery, a common complication is Posterior Capsule Opacification (PCO). It occurs when residual lens epithelial cells proliferate and transform into myofibroblasts, leading to clouding of the posterior capsule which was left intact during surgery to support the intraocular lens.

Given the options:

1. PCO: Typically presents years after the cataract surgery as cloudiness behind the intraocular lens when viewed through a slit lamp, precisely matching the case description.
2. Bullous keratopathy: Characterized by corneal edema and blister-like lesions, usually not directly associated with cataract surgery aftermath, so less likely in this context.
3. Phakic glaucoma: A type of secondary glaucoma related to the lens position, not typically presenting in this manner.
4. Lens subluxation: Involves displacement of the lens, leading to vision problems and apparent even without slit lamp findings.

Hence, considering the commonality, timing, and presentation, Posterior Capsule Opacification (PCO) is the most likely diagnosis.
