RESUMO
PURPOSE: To study the correlation between final visual acuity after successful anatomic macular hole repair and features on spectral domain optical coherence tomography (SD-OCT). METHODS: Retrospective review of charts of patients who underwent macular hole surgery. Data collection included pre- and postoperative best-corrected visual acuity (BCVA), central subfield foveal thickness (CSFT), and presence or absence of inner segment-outer segment (IS-OS) line changes on SD-OCT. Data collected from SD-OCT were correlated with Snellen BCVA, which was converted to logMAR score. Subjects were divided into 2 groups: group I had improvement in BCVA of 2 lines or more and group II improved less than 2 lines or had worsening of BCVA. RESULTS: A total of 35 eyes of 32 patients had successful anatomic closure, which was documented both clinically and on SD-OCT. Mean age of the patients was 74.1 years and 71.2% (23/32) of patients were female. Overall, the mean BCVA changed from 1.01+/-0.38 preoperatively to 0.89+/-0.48 postoperatively (p=0.33). Based on the postoperative visual outcome, 16 eyes belonged to group I and 19 eyes belonged to group II. On the SD-OCT, the mean CSFT was 252.7+/-69.1 microm. No correlation was found between the mean CSFT and BCVA in either group. All the 16 patients in group I had a continuous IS-OS line on SD-OCT at the fovea in contrast to 26.3 % (5/19) of patients in group II (p=0.03). CONCLUSIONS: Establishment of continuity of IS-OS line is an important indicator of visual recovery in eyes with successful anatomic closure of macular hole.
