What is a common predisposing factor for rhegmatogenous retinal detachment?

• A. Hyperopia
• B. Astigmatism
• C. Myopia
• D. Presbyopia

Answer: (C)

High myopia is a major risk factor for rhegmatogenous retinal detachment because the eye is elongated, which stretches and thins the peripheral retina. This promotes lattice degeneration and other peripheral retinal changes that are prone to tearing. When a tear forms, liquefied vitreous can seep under the retina and cause the neurosensory layer to detach from the retinal pigment epithelium. Other refractive errors like hyperopia, astigmatism, or presbyopia don’t create the same degree of peripheral retinal thinning or lattice changes, so they are not as strongly linked to this type of detachment.
