[Problem] The purpose of the present invention is to provide a neuroprotective agent which is capable of effectively protecting intraocular cells including optic nerves and is effective as a composition for ophthalmic membrane staining in cases where removal of an ophthalmic membrane is carried out. [Solution] The purpose is achieved by a neuroprotective agent which contains, as active ingredients: Brilliant Blue G, a pharmaceutically acceptable salt thereof or a harmaceutically acceptable solvate thereof； and triamcinolone acetonide, a pharmaceutically acceptable salt thereof or a pharmaceutically acceptable solvate thereof. This neuroprotective agent has ophthalmic membrane staining effect due to BBG and exhibits extremely high neuroprotective activity due to synergetic effect of Brilliant Blue G and triamcinolone acetonide.
