Metamorphopsia and Optical Coherence Tomography Findings After Rhegmatogenous Retinal Detachment Surgery

In eyes that remained macula-on throughout surgery and had normal-appearing OCT, metamorphopsia did not develop. In some cases, the reason for metamorphopsia was anatomically obvious. In other cases that were preoperative and intraoperative macula-off, postoperative retinal vertical displacement could cause predominantly horizontal metamorphopsia.
