Study finds, Faster progression of Posterior vitreous detach
A Study was conducted to compare the progression of posterior vitreous detachment (PVD) between eyes that underwent cataract surgery and eyes that did not undergo surgery in non-highly myopic patients.

125 eyes of 125 patients scheduled for phacoemulsification and 125 eyes of 125 age-matched patients who did not undergo surgery were enrolled. PVD status was evaluated using swept-source optical coherence tomography at 2 days (baseline), and 1, 3, 6, and 12 months postoperatively, and classified into five stages: 0 (no), 1 (paramacular), 2 (perifoveal), 3 (peripapillary), and 4 (complete). The PVD stage and incidence of progression to complete PVD were compared between groups.

--The mean PVD stage significantly progressed over the 12 months in the surgery group, but did not change significantly in the non-surgery group.

--The PVD stage did not differ significantly between groups at 2 days, or 1, 3, and 6 months postoperatively, but was significantly more progressed in the surgery group than in the non-surgery group at 12 months.

--After adjusting for age, sex, axial length, and baseline PVD stage, the relative risk for progression to complete PVD was 7.1-fold higher in the surgery group than in the non-surgery group.

Finally, PVD proceeded substantially faster in eyes that had cataract surgery than in eyes that did not, and the relative risk of progression to complete PVD was nearly seven-fold higher after one year, demonstrating that the risk of PVD-related disorders is considerable following cataract surgery.
