Analysis of Posterior Vitreous Detachment and Development of Complications Using a Large Database of Retina Specialists.

PURPOSE: To examine the incidence of complications after posterior vitreous detachment (PVD) through an extended follow-up period and to identify patient-specific factors associated with a greater incidence of complication.

DESIGN

Multicenter, retrospective observational study.

PARTICIPANTS

Eyes with acute PVDs between 2015 and 2019 were identified through the Vestrum Health database.

METHODS

Complications (vitreous hemorrhage, retinal break, and retinal detachment) were evaluated after acute PVD at presentation and throughout the 6-month follow-up period.

MAIN OUTCOME MEASURES: Rate of complications throughout the 6 month follow-up period after PVD and odds of complications by patient-specific factors.

RESULTS

A total of 9635 eyes were included. The rate of any complication was 25.0%, isolated vitreous hemorrhage was 13.1%, retinal breaks without detachment was 16.0%, and retinal detachment was 4.2%. The majority of each complication was noted at presentation; however, 8.0% of isolated vitreous hemorrhages, 19.2% of retinal breaks without detachment, and 25.8% of retinal detachments were first noted within the 6-month follow-up period. Men experienced a significantly higher rate of any complication than women (30.0% versus 21.7%, P < 0.001), as well as retinal breaks and retinal detachments at both presentation and within 6-month follow-up. Patients with pseudophakia experienced significantly higher rates of delayed retinal detachment than phakic eyes (odds ratio, 1.85 [1.13, 3.04], P = 0.01). Among eyes with lattice/peripheral retinal degeneration, 44.2% experienced any complication throughout the clinical course. The presence of a retinal break in the fellow eye and retinal detachment in the fellow eye was associated with a significantly increased rate of any complication at any time point (retinal break: P < 0.0001; retinal detachment: P = 0.02), as well as each individual complication within the 6 month follow-up period. Among eyes with vitreous hemorrhage at presentation, 42.0% had a concurrent or delayed retinal break and 10.5% had concurrent or delayed retinal detachments.

CONCLUSIONS

A clinically significant proportion of PVD-related complications are detected late, warranting extended follow-up, especially in higher-risk groups such as men, pseudophakic eyes, eyes with lattice/peripheral retinal degeneration, and eyes with a history of retinal breaks or detachment in the fellow eye.
