%X OBJECTIVE: To compare the progression of posterior vitreous detachment (PVD) after cataract surgery in eyes with high myopia with that in eyes without high myopia.
METHODS: Prospective observational study.
METHODS: Eighty eyes of 80 patients with high myopia and 160 eyes of 160 patients without high myopia scheduled for phacoemulsification were recruited. PVD status was examined using swept-source optical coherence tomography at 2 days postoperatively (baseline) and at 3, 6, and 12 months postbaseline and classified into 5 stages: 0 (no PVD), 1 (paramacular PVD), 2 (perifoveal PVD), 3 (peripapillary PVD), and 4 (complete PVD). The PVD stage and incidence of progression to complete PVD of the 2 groups were compared.
RESULTS: The mean PVD stage did not differ significantly between the groups at baseline or at 3 months postbaseline but was significantly more progressed in the high myopia group than in the nonhigh myopia group at 6 months and 12 months postbaseline (P ≤ 0.0201). The Kaplan-Meier survival rate for complete PVD was significantly lower in the high myopia group (P = 0.0129). After adjusting for age, sex, and baseline PVD stage, the hazard ratio for complete PVD was 1.68-fold higher in the high myopia group than in the nonhigh myopia group (P = 0.0326, 95% CI 1.04-2.70).
CONCLUSIONS: After cataract surgery, PVD progressed significantly faster in eyes with high myopia than in eyes without high myopia, and the relative risk for complete PVD was 1.68-fold higher in eyes with high myopia, suggesting that highly myopic eyes are at considerably high risk for retinal disease postoperatively.
