Incomplete posterior vitreous detachment raises retinal detachment risk post-lens surgery
Myopic eyes with incomplete or absent posterior vitreous detachment (PVD) before lens surgery are at a significantly higher risk of developing retinal detachment (RD) in the postoperative period compared to eyes with complete PVD, according to a poster presented at the 42nd Congress of the ESCRS.
The study tracked 618 eyes with an axial length of ≥ 25.0 mm scheduled for lens surgery over 3 years, as well fellow eyes.
Out of the 939 eyes observed, 13 cases of RD were reported—8 in the study group and 5 in fellow eyes. The cumulative incidence rates were 0.83% at 1 year, 1.31% at 2 years, and 1.56% at 3 years. Of note, eyes with complete PVD at baseline exhibited significantly lower RD rates (0.22% at 1 year vs 0.44% at 3 years) than those with incomplete or no PVD (1.65% at 1 year vs 3.04% at 3 years).
The study concluded that having incomplete or absent PVD before surgery markedly raised the risk of RD, with an unadjusted hazard ratio of 5.62. After adjusting for age, the risk was slightly reduced to a hazard ratio of 4.12.
