Intravitreal triamcinolone for the management of macular edema due to branch vein occlusion

To evaluate the efficacy of intravitreal triamcinolone acetonide in the management of persistent macular edema secondary to branch vein occlusion. 10 consecutive patient were selected with 3 - to 4 month history and persistent macular edema. These patients received a single intravitreal injection of 4 mg of triamcinolone acetonide [40 mg/ml]. The control group including 12 patients did not receive an intravitreal iunjection. The mean follow-up was 8-12 months. A single intravitreal injection of triamcinolone showed significant improvement in the visual acuity [P=0.005], with clinical and angiographic resolution of macular edema in 6 patients [60%] of the 10 patients in the treated group, while only 4 [33.3%] of the 12 patients in the observation group. A single intravitreal injection of triamcinolone acetonide can increased in terms of visual acuity and macular edema for non-ischemic branch vein occlusion

Argon laser transconjunctival suture cutting

This paper reviewed the results of Argon laser in cutting tight scleral flap sutures following trabeculectomy operation. Twenty eight eyes of twenty eight patients with intraocular pressure more than 21 mm Hg. after trabeculectomy operation were selected for this study. Argon laser parameters include 50 microns spot size, 0.l second duration, and power setting of 400-1000 mill watts. The laser was focused on the suture at the corner of the scleral flap. In fourteen out of the twenty eight eyes [50 percent] immediate response to treatment was noticed. In 14 eyes focal pressure was used to enhance the effect of cutting. Two eyes showed drop of IOP to 7 mm Hg. [hypotony] with mild shallowing of the anterior chamber. We conclude that Argon laser can be successfully used to lower IOP after trabeculectomy operation in cases where tight scleral flap suture was the cause of outflow obstruction
