Abstract
To investigate a series of peripheral lattice degeneration cases using an ultra-widefield (UWF) swept-source optical coherence tomography (SSOCT) system (Silverstone, Nikon Healthcare Japan, Inc, Tokyo, Japan). From 1st August, 2022 to 31th July, 2023, nineteen eyes of 16 patients with peripheral lattice degeneration were included. They all underwent a UWF-SSOCT examination. Anatomy of retina, vitreous, and associated pathologic changes were assessed. UWF-SSOCT showed various anatomical changes of retina and vitreous in patients with lattice degeneration. Of fifteen eyes of 12 patients whose UWF-SSOCT images were clearly obtained, 8 eyes showed regional retinal thinning, 7 eyes showed vitreous traction, 2 eyes showed detached vitreous, 3 eyes showed retinal break. UWF-SSOCT can be a useful tool to understand anatomical changes and pathophysiology of peripheral lattice degeneration.
