Methods: A retrospective analysis was conducted on 293 patients initially diagnosed at the Department of Ophthalmology of the Affiliated Hospital of Qingdao University from January 2019 to September 2023, who suffered from rhegmatogenous retinal detachment (RRD) and underwent vitrectomy combined with silicone oil tamponade. A comprehensive range of ophthalmic examinations was conducted, encompassing best-corrected visual acuity (BCVA), optical coherence tomography (OCT), static visual field, visual evoked potential (VEP), and electroretinography (ERG). Results: In 293 eyes that underwent vitrectomy with silicone oil tamponade for RRD, 20 eyes (6.83%) demonstrated a decline in vision (SORVL). The incidence of silicone oil-related vision loss (SORVL) was approximately 13.33% in eyes with macular attachment before surgery and 4.59% in eyes with macular detachment. The mean thickness of the ganglion cell layer (GCL) in the macular region of patients who developed SORVL was significantly thinner after surgery than before surgery (P < 0.001), and P-VEP 15 min showed a significant delay in the peak of the P100 wave and a significant decrease in its amplitude;FVEP showed a significant decrease in the amplitude of the P2 wave. Conclusion: Eyes with macular attachment are at a higher risk of experiencing silicone oil-related vision loss than those with macular detachment, and patients with SORVL may have damage to the ganglion cells of the macular central sulcus. In the event of SORVL, silicone oil should be removed as soon as the retina is well restored.展开更多
