Indications and Outcomes of Laser Retinopexy in Eyes With High-Risk Lattice Degeneration.

Purpose: To examine the characteristics of eyes with high-risk lattice degeneration treated with laser retinopexy and determine the indications, safety, and outcomes of the treatment. Methods: This interventional single-surgeon consecutive retrospective study was conducted at Wills Eye Hospital between 2014 and 2021. The series included eyes with lattice degeneration with high-risk lesions. Documented characteristics and outcomes of these eyes and fellow eyes were documented. Results: The study comprised 167 eyes of 143 patients (53.3% women; mean age [±SD], 50 ± 17 years). Complications after laser treatment included new posterior vitreous detachment (PVD) (n = 21), epiretinal membrane (ERM) (n = 13), retinal detachment (RD) (n = 5), and additional laser required (n = 22). Eyes that developed ERMs were more likely to develop PVDs (odds ratio, 5.39; 95% CI, 1.57-18.47). Patents who developed ERMs were older (mean, 60 ± 7 years vs 49 ± 17 years; P  = .016), as were those developing PVDs (mean, 59 ± 8 years vs 48 ± 17; P  = .005). No eye with a new ERM required surgery (n = 13). Four eyes with a new RD required laser retinopexy alone; 1 eye was treated surgically. No eye had an RD at the most recent evaluation. Conclusions: Despite high-risk lesions in areas of lattice degeneration, few eyes developed RDs after prophylactic laser retinopexy. Older patients may have a higher risk for ERM or PVD after laser treatment. Eyes with post-laser PVD were more likely to develop an ERM.
