Abstract

PURPOSE: To investigate the efficacy and safety of A0001 (brilliant blue G250) for visualization of the internal limiting membrane (ILM) during and after vitrectomy.

METHODS: Patients (n = 31) requiring ILM peeling during vitrectomy were enrolled in this clinical trial. After injection of A0001 (range: 0.0625 to 0. 125 mg), the staining grade and the peeling ease of the ILM were evaluated in five steps (levels 0 to 4). The safety of A0001 was investigated for 7 days after surgery.

RESULTS: From the evaluation of a primary endpoint by the Independent Data Monitoring Committee (IDMC) and a secondary endpoint by each surgeon, A0001 was effective in all cases at three or more levels ( ≥ level 2 was defined as effective) for evaluation of the grade of visualization and operating ease. Adverse events occurring in two or more cases included elevated intraocular pressure, eye pain, eye discharges, and retinal bleeding. One serious adverse event was a case of unclosed macular hole after vitrectomy, but the patient recovered after reoperation.

CONCLUSIONS: A0001 was effective and safe for visualization of the ILM during vitrectomy, and there was an improvement in ease of operation.
