Peripheral Lattice Degeneration Imaging with Ultra-Widefield Swept-Source Optical Coherence Tomography

Abstract

Purpose: To investigate a series of peripheral lattice degeneration cases using an ultra-widefield (UWF) swept-source optical coherence tomography (SS-OCT) system.Methods: From August 1, 2022 to July 31, 2023, 19 eyes from 16 patients with peripheral lattice degeneration were included. They all underwent a UWF SS-OCT examination. Anatomy of retina, vitreous, and associated pathologic changes were assessed.Results: UWF SS-OCT showed various anatomical changes of retina and vitreous in patients with lattice degeneration. Of 15 eyes from 12 patients whose UWF SS-OCT images were clearly obtained, eight eyes showed regional retinal thinning, seven eyes showed vitreous traction, two eyes showed detached vitreous, and three eyes showed retinal break.Conclusions: UWF SS-OCT can be a useful tool to understand anatomical changes and pathophysiology of peripheral lattice degeneration.
