Purpose: To compare the functional and anatomical outcomes of treating patients with ischemic central retinal vein occlusion using triamcinolone alone or triamcinolone with vitrectomy Methods: This is a prospective, longitudinal, investigational and comparative case series of patients with ischemic CRVO and visual acuity of <20/100. Patients were a signed to either receive intravitreal triamcinolone injection alone (group A=6) or to undergo vitrectomy with intravitreal triamcinolone (group B = 10). Visual acuity, flourecein angiografy (FAG), optical coherence tomography (OCT) measurement of the central foveal thickness, and multifocal ERG were done before and at 3 months after the intervention. Eyes with rubeosis or previous laser treatment were excluded Results: This is a prospective, longitudinal, investigational and comparative case series of patients with ischemic CRVO and visual acuity of <20/100. Patients were a signed to either receive intravitreal triamcinolone injection alone (group A=6) or to undergo vitrectomy with intravitreal triamcinolone (group B = 10). Visual acuity, flourecein angiografy (FAG), optical coherence tomography (OCT) measurement of the central foveal thickness, and multifocal ERG were done before and at 3 months after the intervention. Eyes with rubeosis or previous laser treatment were excluded Conclusions: Although we did not obtain a statistically significant difference between the two groups due to the limited number of patients, pars plana vitrectomy with triamcinolone acetonide for the treatment of ischemic CRVO appears to have a better functional and anatomical outcomes compared to triamcinolone injection alone with minimal complications.
