Characteristics of macular microstructure changes after surgery for high myopia with macular hole retinal detachment and their correlation with visual function
Abstract
AIM: To observe the variation characteristics of postoperative optical coherence tomography(OCT), optical coherence tomography angiography(OCTA)examination indicators in patients with high myopia and macular hole retinal detachment(MHRD), and analyze their correlation with visual function.METHODS: A total of 78 MHRD patients with high myopia who were treated in the Baoding No.1 Central Hospital from January 2019 to October 2023 were selected as the study objects, all of which underwent vitrectomy combined with internal limiting membrane tamponade. The changes in the best corrected visual acuity(BCVA), OCT and OCTA parameters, including choriocapillary blood flow area(CBFA), diameter of ellipsoid zone absence(DEZA)and blood flow density were observed at 1, 3 and 6 mo after surgery. Pearson correlation analysis and multiple linear regression analysis were conducted to analyze the correlation between BCVA and CBFA, DEZA, and blood flow density at different time points after surgery.RESULTS: BCVA of enrolled patients at 1, 3, and 6 mo after surgery were 1.75±0.79, 1.49±0.53, and 1.08±0.44, respectively, and the differences at different points were statistically significant(all P0.05). However, CBFA was negatively correlated with BCVA(LogMAR; P<0.05); at 3 and 6 mo after surgery, CBFA and blood flow density were negatively correlated with BCVA(LogMAR)in patients with high myopia and MHRD, while DEZA was positively correlated with BCVA(LogMAR; all P<0.05). Multiple linear regression analysis showed that CBFA, blood flow density, and DEZA were important influencing factors of BCVA at 3 and 6 mo after surgery(all P<0.05).CONCLUSION:Visual function of patients with high myopia and MHRD gradually increases after surgery, and is closely related to postoperative CBFA, DEZA and blood flow density. It is recommended to regularly monitor changes in OCT and OCTA indicators after surgery.
