Rhegmatogenous retinal detachment (RRD) is most commonly associated with which predisposing ocular condition?
- A Myopia greater than -3 D with associated lattice degeneration ✓
- B Hypermetropia greater than +5 D
- C Esotropia with high AC/A ratio
- D Congenital cataract
Explanation
Myopia (particularly >-3 D) is the most important risk factor for RRD due to elongated axial length, thinner peripheral retina, and vitreous liquefaction predisposing to posterior vitreous detachment (PVD) at an earlier age. Lattice degeneration (seen in 8% of the population, 30–40% of RRD cases) is the most important peripheral retinal degeneration predisposing to retinal breaks — occurring at the interface of lattice degeneration with normal retina. Combined, myopia with lattice degeneration dramatically increases RRD risk. Hypermetropes have short axial length and smaller, less susceptible retinas.
