Which condition is most likely to occur if corneal oxygen supply is reduced over time?

Which condition is most likely to occur if corneal oxygen supply is reduced over time?

• A. Corneal Neovascularization
• B. Myopia Progression
• C. Cataract Formation
• D. Retinal Detachment

Answer: (A)

When the cornea experiences low oxygen, it becomes hypoxic and signals the surrounding blood vessels to grow into the normally clear corneal tissue. The cornea relies on oxygen from the air through the tear film, and without sufficient supply, hypoxia triggers angiogenic factors (like VEGF) that prompt new vessels to invade from the limbus. This corneal neovascularization disrupts transparency and can lead to scarring or edema, harming vision. Other conditions listed aren’t driven directly by corneal oxygen deficiency. Myopia progression relates to changes in eye shape and focusing power, not oxygen supply. Cataract formation involves changes in the lens proteins over time, and retinal detachment concerns the retina and vitreous, not the cornea’s oxygen status.
