Laser photocoagulation combined with intravitreal injection of triamcinolone acetonide for the treatment of macular edema in branch retinal vein occlusion

Objective To observe the effect and safety of laser photocoagulation combined with intravitreal injection of triamcinolone acetonide for the treatment of macular edema in branch retinal vein occlusion(BRVO).Methods Fundus fluorescein angiography(FFA) was conducted in 20 patients(22 eyes) with BRVO.Intravitreal injection of triamcinolone acetonide 0.1ml /(4mg) was given after macular grid photocoagulation.The patients were followed up for 9 months for observation before undergoing FFA again and optic coherence tomography(OCT) examination.Results Patients' visual acuity was markedly improved,with average vision increasing by 3 rows.Macular edema disappeared or reduced.One patient with a case history of 2 years had his visual ability increased from 0.08 to 0.2.One patient had intraocular pressure(IOP) increased,which was controlled by medication.2 cases showed no effect.Conclusion Macular grid pattern laser photocoagulation combined with triamcinolone acetonide for the treatment of macular edema in BRVO is safe and effective.
