Journal Title: Guoji Yanke Zazhi - Year 2018, Vol 18, Issue 8
Abstract
AIM:To investigate the clinical efficacy of retrobulbar or intravitreal injection of triamcinolone acetonide combined with 532nm laser photocoagulation in the treatment of diabetic macular edema(DME). <p>METHODS: Sixty-two eyes in 40 DME patients were divided into two groups(Group A and Group B)randomly. Thirty-one eyes in Group A were treated with retrobulbar injection of triamcinolone acetonide(RBTA)and 31 eyes in Group B were treated with intravitreous injection of triamcinolone acetonide(IVTA). Eyes with limited macular edema were treated by local direct retinal laser, those with diffuse and cystic macular edema were treated by grid retinal laser using Vitra 532nm fundus lasers at 1mo after injection. Visual acuity, intraocular pressure, fundus, macular edema and complications were recorded after 1wk, 1, 3 and 6mo in the follow-up study. <p>RESULTS: The mean best corrected visual acuity was improved and macular edema subsided after treatment in the two groups in the follow-up study at 1wk, 1, 3 and 6mo(<i>P</i><0.05), while there had no significant difference between groups(<i>P</i>>0.05). In Group A, significant efficiency rate was 39%(12/31), total effective rate was 90%(28/31). In Group B, significant efficiency rate was 39%(12/31), total effective rate was 94%(29/31). The follow-up study showed no retinal detachment, endophthalmitis, intraocular hemorrhage and other complications. <p>CONCLUSION: Triamcinolone acetonide injection combined with laser photocoagulation is an effective method for treatment of DME with significant effect, less adverse reactions, patient's vision improved effectively and macular edema reduced. No significant difference was noted in the treatment of DME between RBTA and IVTA.
