Giant Retinal Tears: Long-Term Outcomes of Fellow Eyes
Background And Objective:
Determine clinical characteristics and long-term outcomes of fellow eyes for patients with prior repair of rhegmatogenous retinal detachments due to a giant retinal tear (GRT).
Study Design:
Retrospective case series of patients who underwent vitreoretinal surgery between January 2005 and August 2017 for GRT at the Bascom Palmer Eye Institute with a minimum of one year of follow-up information. Patients with a traumatic or post-vitrectomy GRT were excluded.
Main Outcome Measures:
Visual acuity and rate of retinal events in fellow eyes.
Results:
The study group included 51 patients; 40 others were excluded due to having less than one year of follow-up (n = 27), a history of inciting trauma (n = 11), or a GRT occurring post-vitrectomy (n = 2). The mean age was 49.9 years (range 14 to 81) and mean follow-up duration was 6.9 years (range 1 to 16). During the follow-up interval, prophylactic laser retinopexy was performed in 5 fellow eyes for retinal breaks (9.8%) and in one fellow eye with a progressing retinoschisis cavity (2.0%). One patient had a previous history of a retinal break in the fellow eye. Vitreoretinal surgery was performed in 6 (11.8%) fellow eyes for rhegmatogenous retinal detachments, of which one was caused by a GRT. Three patients (5.9%) already had a retinal detachment repair in the fellow eye prior to presentation and one patient presented with bilateral giant retinal tear associated retinal detachments (GRT-RDs) at the initial visit. Overall, there was a retinal event in 33.3% of fellow eyes. Myopia was the most commonly documented associated factor (31%), followed by lattice degeneration (22%), and known or suspected inherited vitreoretinopathy (4%).
Conclusions:
Retinal tears and/or detachments were encountered relatively frequently in the fellow eye of patients with a history of GRT-RD during follow-up, but the rate of GRTs in the fellow eye (4%) was below what has been generally reported in the literature. Regular dilated fundus exams are warranted for patients with a history of GRT. [.
