What does the presence of cloudy cornea indicate in glaucoma patients?

• A. Normal hydration levels
• B. Corneal scarring
• C. Corneal edema
• D. Healthy corneal thickness

Answer: (C)

The presence of a cloudy cornea in glaucoma patients is indicative of corneal edema. In glaucoma, elevated intraocular pressure can compromise the normal function of the corneal endothelium, which is responsible for maintaining corneal hydration and clarity. When the endothelial cells are unable to pump excess fluid out of the cornea effectively, fluid accumulates, leading to swelling or edema. This condition disturbs the cornea's regular curvature and transparency, resulting in a cloudy appearance. In contrast, normal hydration levels would maintain corneal clarity, while corneal scarring typically presents with opacities that differ from edema in both appearance and etiology. Healthy corneal thickness usually corresponds with a clear cornea, not one that is cloudy due to fluid buildup. Thus, recognizing that cloudy cornea in the context of glaucoma points to corneal edema is essential for understanding the implications of intraocular pressure on corneal health.
