Submacular deposition of triamcinolone acetonide after triamcinolone-assisted vitrectomy

PURPOSE: We describe a case demonstrating a submacular deposition of triamcinolone acetonide (TA) after a TA-assisted vitrectomy for retinal detachment. DESIGN: Interventional case report. METHODS: A 48-year-old Japanese man with rhegmatogenous retinal detachment in his left eye underwent a TA-assisted vitrectomy, endolaser photocoagulation, and sulfur hexafluoride (SF₆) gas tamponade. RESULTS: At the end of the surgery and the day after undergoing vitrectomy, the deposition of TA was observed between the retinal pigment epithelium and neurosensory retina in the submacular area. These TA granules disappeared after 2 weeks. Two months after the operation, the retina was observed to be successfully attached and no abnormality was observed in the macula. The patient's visual acuity improved to 20/16, and no ophthalmoscopic or functional damage was observed. CONCLUSION: No apparent adverse effect was found in this case demonstrating a submacular deposition of TA.
