Summary
Refractive surgery is not recommended for patients with posterior polymorphous dystrophy (PPD). Low endothelial cell density in PPD patients may lead to corneal decompensation after laser vision correction.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Ocular Surface Disease
Background:
- Patient presented for refractive surgery consultation.
- Clinical examination revealed findings suggestive of posterior polymorphous dystrophy (PPD).
Observation:
- Vesicle and band-like lesions were observed at Descemet's membrane and the endothelium.
- Endothelial cell density was lower than normal.
Findings:
- The observed lesions and low cell count are indicative of PPD.
- Specular microscopy is crucial for diagnosis, even without apparent corneal decompensation.
Implications:
- Posterior polymorphous dystrophy can be a contraindication for refractive surgery.
- Reduced endothelial cell count in PPD patients increases the risk of corneal decompensation following laser vision correction procedures like LASIK.

Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
