Abstract:Objective To investigate the effect of vitrectomy combined with internal limiting membrane peeling (ILMP) on macular structure and function in high myopia patients with macular hole retinal detachment (MHRD) and analysis of the influencing factors of macular hole closure after operation. Methods Clinical data of 69 patients with MHRD with high myopia treated with vitrectomy and ILMP in Hebei Handan Eye Hospital from February 2016 to August 2018 were retrospectively analyzed. According to the follow-up results of macular hole closure at three months after operation, they were divided into closed group (57 cases) and unclosed group (12 cases). All patients underwent optical coherence tomography, slit lamp microscopy and best corrected visual acuity before and after surgery. The changes of foveal retinal thickness (FRT), sub foveal choroidal thickness (SFCT), and the parameters and index of macular hole before and after operation were measured. Combined with clinical data of the patients, univariate and multivariate logistic regression models were used to analyze the influencing factors of macular hole closure. Results There were no significant differences in FRT and SFCT between two groups before operation (P > 0.05). After operation, FRT and SFCT of two groups were thinner than those before operation, and closed group was thinner than that unclosed group, the differences were statistically significant (P < 0.05). There were significant differences in MD, MHI and THI between two groups (P < 0.05). Multivariate logistic regression analysis showed that MD (OR = 1.003, 95%CI: 1.000-1.005, P = 0.048), MHI (OR = 108.369, 95%CI: 5.047-2326.771, P = 0.003) and THI (OR = 215.263, 95%CI: 2.248-20 609.444, P = 0.021) were independent risk factors for macular hole closure. Conclusion Vitrectomy combined with ILMP can significantly improve the macular structure and function in MHRD patients with high myopia. MD, MHI and THI are risk factors for macular hole closure.
