PURPOSE: To report optical coherence tomography and microperimetric correlated changes in a case of bilateral foveal schisis in progressive X-linked retinoschisis (XLRS) treated with vitrectomy, inner limiting membrane (ILM) peeling, and air tamponade. METHODS: One case report. RESULTS: An 18-year-old boy with bilateral foveal schisis in progressive XLRS underwent vitrectomy, ILM peeling and air tamponade in both eyes. At baseline and follow-up (1 month in right eye, 6 months in left eye), visual acuity test, optical coherence tomography, retinal sensitivity map, and fixation stability study were performed. At the end of follow-up, in both eyes, the largest foveal schisis cavities resolved, central macular thickness and volume on optical coherence tomography decreased, and visual acuity improved. In right eye, the mean retinal sensitivity is worsened after 1 month from surgery and conversely central macular sensitivity improved; in left eye, retinal sensitivity improved overall after 6 months from surgery; fixation became more stable in both eyes. There were no adverse events. CONCLUSION: Retinal sensitivity and fixation behavior analysis could be a complementary tool respect in addition to visual acuity test and optical coherence tomography to investigate the efficacy of vitrectomy with ILM in progressive X-linked foveal schisis to prevent functional impairment before it happens.
