Correlations between Spectral Domain Optical Coherence Tomography Measurements and Visual Acuity in Patients with Retinitis Pigmentosa at Baseline and One-Year Follow-Up

EZ foveal sparing is a significant predictor of visual acuity in RP patients regardless of the presence of CME. While CRT correlates with visual acuity in patients without CME, it does not predict outcomes in those with CME. TMV may serve as a marker for preclinical CME, and both increased TMV and ERM presence may predict visual decline in RP patients with undetectable CME on SD-OCT.
