Incidence and Risk Factors for Delayed Retinal Tears after an Acute, Symptomatic Posterior Vitreous Detachment

Area of Science:

• Ophthalmology
• Retinal Diseases
• Vitreoretinal Surgery

Background:

• Posterior vitreous detachment (PVD) is common, often presenting with symptoms like flashes and floaters.
• While many PVD cases resolve without complication, delayed retinal tears can occur.
• Identifying risk factors for delayed tears is crucial for patient management.

Purpose of the Study:

• To investigate the long-term incidence of delayed retinal tears following acute, symptomatic PVD.
• To identify risk factors associated with the development of these delayed retinal tears.

Main Methods:

• A retrospective, observational case series included 389 patients diagnosed with acute, symptomatic PVD without concurrent retinal tears.
• Data collected included patient demographics, refractive error, lens status, lattice degeneration, and physician type.
• Time to delayed retinal tear development was the primary outcome, analyzed using Kaplan-Meier and Cox-Mantel log-rank analyses.

Main Results:

• 7.39% of eyes developed delayed retinal tears within 6.24 years of PVD diagnosis.
• Half of these tears occurred within 4.63 months, and 63.46% within one year.
• Younger age (<60), myopia, and lattice degeneration were associated with increased tear risk, with lattice degeneration being a significant independent risk factor.

Conclusions:

• A notable percentage of patients with PVD develop delayed retinal tears, often beyond typical follow-up periods.
• Lattice degeneration is a significant predictor of delayed retinal tear formation.
• Findings support refining follow-up protocols for PVD patients, especially those with identified risk factors.
