| Popis: | To evaluate the outcomes of macular hole (MH) surgery with 3-day prone positioning in highly myopic eyes and to compare them with those from non-highly myopic eyes.Retrospective nested case-control study from a cohort of 496 consecutive patients (496 eyes) who underwent surgery for MH.Forty-seven highly myopic eyes (with axial length26 mm) were included in the study group and were matched for MH size and duration of symptoms with 47 non-highly myopic control eyes selected from the same cohort.All patients underwent pars plana vitrectomy, internal limiting membrane peeling, and 17% hexafluoroethane gas filling. Patients then were advised to maintain strict face-down positioning for 3 days only and to avoid the supine position during the night for a minimum of 1 week.The MH closure rate, the relationship between axial length and closure rate, the best-corrected visual acuity (BCVA), and the surgical complications were analyzed.The mean axial length was 28.5±2.2 mm in highly myopic eyes and 23.3±1.1 mm in controls (P 0.001). Closure of the MH was achieved in 39 of 47 eyes (83%) in the study group and in 45 of 47 eyes (95.7%) in the control group (P = 0.045). Anatomic outcomes tended to decrease when axial length increased (P = 0.066). Mean BCVA improved in both groups (0.41±0.39 logarithm of the minimal angle of resolution [logMAR] vs. 0.68±0.34 logMAR) but was significantly lower in highly myopic eyes (P 0.001). Retinal detachment occurred in 8.5% of highly myopic patients versus 2.1% of controls, but the difference was not significant.Macular hole surgery with 3-day postoperative positioning in highly myopic eyes resulted in satisfactory anatomic and functional outcomes. However, the MH closure rate and mean improvement of visual acuity were less favorable than those in control eyes. Longer axial length may increase the risk of anatomic failure. |
