RESUMEN

Objective:To observe the clinical effects of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) peeling and C 3F 8 tamponade for patients with highly myopic macular hole (HM-MH) with and without foveoschisis. Methods:A retrospective case controlled study. From January 2017 to February 2022, 23 eyes of 23 patients with highly myopic macular hole with and without foveoschisis diagnosed in the Shandong Eye Hospital were included in the study. Among them, 5 males had 5 eyes, and 18 females had 18 eyes, the age was (54.43±12.96) years old. The patients with or without foveoschisis were 12 eyes in 12 cases and 11 eyes in 11 cases. Studies were divided into two groups, depending on the presence of a concomitant myopic foveoschisis or not. The groups are high myopia macular hole with foveoschisis (group A) and high myopia macular hole without foveoschisis (group B). Best-corrected visual acuity (BCVA), B-scan ultrasonography, optical coherence tomography and axial length (AL) measurement were performed in all eyes. Snellen chart was used for BCVA examination, and the visual acuity was converted into logarithm of minimum angle of resolution (logMAR) during statistics. The age of the two groups, sex, macular hole (MH) diameter, logMAR BCVA, AL, posterior scleral staphyloma, there was no significant difference ( P>0.05). PPV combined with ILM peeling and C 3F 8 filling were performed in all eyes. Follow-up was at least 3 months after the last operation. BCVA changes and MH closure were compared between the two groups after surgery. Wilcoxon test was used to compare BCVA before and after operation. Mann-whiteny U test was used to compare preoperative and postoperative BCVA between groups. Results:After initial surgery, MH was closed in 17 of 23 eyes (74%, 17/23). MH was closed in 8 eyes in group A (66.7%, 8/12). Four eyes were not closed (33.3%, 4/12); MH closed in 9 eyes in group B (81.8%, 9/11). There was no significant difference between the two groups after initial operation ( P>0.05). At 1 and 3 months after surgery, the logMAR BCVA of patients in group A and group B were 1.00±0.46, 1.03±0.83 and 0.53±0.63, 0.55±0.41, respectively. Compared with before operation, there was no significant difference at 1 month ( P=0.783, 0.358), but the difference was statistically significant at 3 months ( P=0.012, 0.007). There was no significant difference in logMAR BCVA between group A and group B at 1 and 3 months after operation ( P=0.687, 0.950). Conclusion:PPV combined with ILM peeling and C 3F 8 tamponade can promote MH closure and improve visual acuity in most affected eyes with HM-MH with and without foveoschisis.
