The study aimed to assess preoperative OCT findings of foveal-splitting retinal detachment patients and determine postoperative outcomes. It was found that patients with foveal-splitting RD had better preoperative visual acuity compared to macula-Off eyes and similar postoperative visual acuity to macula-On eyes after 1 year.
Purpose: To assess preoperative optical coherence tomography (OCT) findings of foveal-splitting retinal detachment (RD) and determine postoperative outcomes. Methods: Consecutive patients who underwent RD surgery over a 1-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. Visual acuity (VA) after 1 year of macula-On/Off, macula-On, and macula-Off eyes was compared. Results: A total of 85 eyes were included, 8 of which had a macula-On/Off RD. On preoperative OCT, all macula-On/Off RD eyes had foveal detachment extending beyond the foveal center over a median distance of 632 mu m. Mean VA of the macula-On/Off eyes had improved from 20/160 to 20/40 at 1 year postoperatively (p = 0.035). The 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 1 year, the VA of macula-On/Off eyes was no different from that of the macula-On eyes (p = 0.320), and tended to be better than that of the macula-Off eyes (p = 0.062). Conclusion: Preoperative OCT revealed a shallow RD extending beyond the foveal center in eyes with clinical foveal-splitting RD. These eyes, termed macula-On/Off RD eyes, had a preoperative VA between macula-On and macula-Off eyes, while their final VA was close to those with macula-On RD.
