We investigated the efficacy of intravitreal injection of triamcinolone acetonide for the treatment of intractable macular edema. Methods: A prospective study was conducted in 17 patients ( 18 eyes) with a diagnosis of macular edema unresponsive to conventional treatment, resulting from inflammatory or retinal vascular diseases. The underlying diseases associated with the development of macular edema were: diabetic retinopathy (6 eyes), branch retinal vein occlusion (5 eyes), Irvine-Gass syndrome (3 eyes), and central retinal vein occlusion (4 eyes). Triamcinolone acetonide 4 mg was injected intravitreally. Ophthalmological examinations, fundus photography, fluorescein angiography, and optical coherence tomography were performed before treatment, 3 months and 6 months after treatment. During the follow-up period, recurrent macular edema was retreated with the same dosage and followed for another 6 months . Results: Sixteen eyes received a single injection and 2 others (11%) underwent reinjection after the 3-month follow- up examination. Among the eyes that received a single injection , 10 (63%) showed visual acuity gain of 2 or more Snellen lines at the 6-month follow-up. The pretreatment central macular thickness averaged 581 min and reduced to 215 turn at the 6-month follow-up. In the 2 eyes that received reinjection, macular edema also showed significant reduction 6 months after retreatment. Sterile endophthalmitis was noted in 3 eyes (17%). Two eyes (11%) developed significant cataract. Three eyes (17%) developed high intraocular pressure ; 1 of them (5.5%) ultimately required filtering surgery. Conclusions: Intravitreal injection of triamcinolone temporarily reduced refractory macular edema. Potential complications should be monitored after treatment . |
