title: Peristence of triamcinolone crystals after intra-vitreal injection: benign crystalline hyaloidopathy.
abstract: We report a case of unusually long persistence of triamcinolone crystals after intra-vitreal injection. Crystals were noted on fundus examination predominantly confined to the posterior pole. Optical coherence tomography localized the crystals to the posterior hyaloidal surface. Over 6 years of follow-up the patient has retained good visual acuity and no observable changes in the retina. As the condition clinically resembles both crystalline maculopathy and asteroid hyalosis, we suggest the term 'drug-induced benign crystalline hyaloidopathy'.
