Corneal endothelial changes in pseudoexfoliation syndrome.

Area of Science:

• Ophthalmology
• Corneal Science
• Cell Biology

Background:

• Pseudoexfoliation syndrome is an ocular condition that can affect corneal health.
• Understanding corneal endothelial changes is crucial for managing pseudoexfoliation syndrome.

Purpose of the Study:

• To investigate corneal endothelial cell density and morphology in patients with pseudoexfoliation syndrome.
• To compare endothelial changes in affected eyes, unaffected fellow eyes, and normal control eyes.

Main Methods:

• Specular microscopy was used to examine the corneal endothelium.
• Computer-assisted morphometry quantified cell density, size (polymegethism), and shape variability (pleomorphism).
• Study included eyes with pseudoexfoliation syndrome, their fellow eyes, and normal control eyes.

Main Results:

• Eyes with pseudoexfoliation syndrome exhibited significantly lower corneal endothelial cell density compared to controls.
• Both affected and apparently normal fellow eyes showed significant polymegethism and pleomorphism.
• These endothelial changes were consistent across affected and unaffected eyes in unilateral cases.

Conclusions:

• Corneal endothelial cell changes are a consistent finding in pseudoexfoliation syndrome.
• These morphologic alterations may serve as an early diagnostic sign of the disorder.
• The findings highlight the systemic nature of pseudoexfoliation syndrome affecting corneal endothelium.
