Preoperative Optical Coherence Tomography Findings of Foveal Splitting Rhegmatogenous Retinal Detachment

To assess preoperative optical coherence tomography (OCT) findings of foveal splitting retinal detachment (RD), and to determine their postoperative outcomes. Consecutive patients who underwent RD surgery over a one-year period were included. Patients diagnosed with a detachment extending to the edge of the fovea on fundus examination (i.e. macula-On/Off) underwent macular OCT scanning. One-year visual acuity (VA) of macula-On/Off, macula-On and macula- Off eyes was compared. 85 eyes were included, of which 8 had a macula-On/Off RD. On preoperative OCT, all macula-On/Off RD had a foveal detachment extending beyond the foveal center, over a median distance of 632 µm. Mean VA of macula-On/Off eyes improved from 20/160 to 20/40 at one year postopera tively (p=0.035). Preoperative VA of macula-On/Off eyes was significantly better than macula-Off eyes (p=0.032) and lower than macula-On eyes (p=0.004). At one year, VA of macula-On/Off eyes was not different from macula-On eyes (p=0.320), and tend to be better than macula-Off eyes (p=0.062). Preop erative OCT revealed a shallow RD extending beyond the foveal center in eyes with clinical foveal splitting RD. These eyes called macula-On/Off RD had preopoerative VA between macula-On and macula-Off eyes, while their final VA was close to those with macula-On RD.
