Classification of macular abnormalities in the study cohort of RP patients, stratified by (a) Sex; (b) Age; (c) Lens status. a Bar graph showed no significant differences among the classifications of macular abnormalities and sex (CME: p = 0.193; VMT: p = 0.176; MH: p = 0.383), except for ERM (males: 55.7%; females: 46.3%; p = 0.006). b This bar graph revealed prevalence of ERM (p = 0.001) and MH (p = 0.008) were significantly increased with age, while no differences were observed in CME (p = 0.283) and VMT (p = 0.619) distributions among age groups. c ERM (p < 0.001) and VMT (p = 0.003) were significantly more frequent in pseudophakic and aphakic eyes than in unoperated eyes (clear lens and cataracts). Abbreviations: ERM: epiretinal membranes; CME: cystoid macular edema; MH: macular hole; VMT: vitreomacular traction syndrome
