Efficacy and safety of multiple intravitreal triamcinolone injections for refractory diabetic macular oedema.

Journal Article

AIM: The efficacy and safety of repeated injections of intravitreal triamcinolone (IVTA) for diabetic macular oedema is unclear, with results of previous reports conflicting. METHODS: This is a prospective, observational case series of 27 eyes receiving IVTA for diabetic macular oedema. LogMAR visual acuity (VA) and central macular thickness (CMT) were measured at baseline and in 3 to 6 monthly intervals for up to 24 months, then correlated with the number of IVTA injections given. RESULTS: One IVTA injection was required in 6 (18%) eyes, 2 in 8 (24%) eyes, 3 in 13 (39%) eyes and 4-5 in 6 (18%) eyes. VA improved in all patients, but neither the final improvement in VA nor the absolute improvement in CMT from baseline to 24 months correlated with the number of injections received (p = 0.44 and 0.84, respectively). Cataract surgery was more frequent in eyes receiving more injections (p = 0.01). CONCLUSIONS: This study suggests that repeated injections of IVTA continue to be as effective as the first over a 2-year period. The probability of cataract surgery increases with an increasing number of injections.
