Combined Cataract and Retina Surgery for Granular Corneal Dystrophy with Rhegmatogenous Retinal Detachment：a case report

Background Granular corneal dystrophy with rhegmatogenous retinal detachment is relatively rare, and the granular opacities in the cornea can interfere with fundus examination and surgical treatment. This article presents the diagnosis and surgical management of a patient with granular corneal dystrophy combined with rhegmatogenous retinal detachment, and discusses the possible underlying pathogenesis. Case presentation: We describe the clinical course of a 51-year-old female patient with granular corneal dystrophy complicated by rhegmatogenous retinal detachment, who underwent combined cataract and retinal surgery with silicone oil tamponade. One year postoperatively, following silicone oil removal, her visual acuity remained stable at 0.1. Conclusion Although the co-occurrence of granular corneal dystrophy and rhegmatogenous retinal detachment is relatively rare in clinical practice, this case provides insights into retinal surgery under suboptimal corneal conditions. Moreover, it underscores the necessity of timely fundus examination for such patients.
