Intravitreal versus Posterior Subtenon Injection of Triamcinolone for Macular Edema with Branched Retinal Vein Occlusion
Donghyun Jee, Tae Yoon Ra
To anterospectively evaluate the clinical results of intravitreal (IVT) and posterior subtenon (PSTT) injection of triamcinolone acetonide (TA) for macular edema with branched retinal vein obstruction (BRVO). Methods: Twenty five eyes of 25 patients with macular edema of BRVO was assigned two groups. 13 eyes in IVT group received intravitreal TA injections (4 mg/0.1 ml) and 12 eyes in PSTT group received subtenon TA injections (20 mg/0.5 ml). Central Macular Thickness, visual acuity, and intraocular pressure were measured at before and 1, 3, 6 month postoperatively. Results: The mean CMT was significantly dereased at 1 month postoperatively in IVT group, and at 3 months postoperatively in PSTT group. And the recuction was maintained until 6 month postoperatively in both groups. The mean CMT in IVT group was significantly more decreased than PSTT group at 1 month postoperatively. Visual acuity in IVT group was significantly more improved than PSTT group at 1 month postoperatively. And there is no worseness of CMT and visual acuity in both group. The percentage increase of IOP was significantly higher in IVT group than PSTT group in 1 week, 1 month postoperatively. Conclusions: IVT injection seems to have more rapid action on BRVO-associated macular edema than PSTT injection. But IVT injection has more risk of IOP increase. PSTT injection also seems to be a safe and effective injection for BRVO-associated macular edema. (Korean J Optom Vis Sci 2011;10(1):29-36)
