Intravitreal anti-VEGF therapy as an adjunct to laser photocoagulation for severe aggressive posterior retinopathy of prematurity
AbstractPurposeThe aim of the study was to evaluate the role of anti-VEGF therapy as an adjunct to laser ablation therapy in severe aggressive posterior retinopaty of prematurity (AP-ROP).MethodsMedical records of premature infants with a primary diagnosis of AP-ROP treated with 0.625mg/0.025ml intravitreal bevacizumab (IVB) in addition to standard laser photocoagulation as a salvage therapy or primarily combined with laser in a university clinic were reviewed, retrospectively. The anatomical results and complications were evaluated after treatment.Results15 eyes of 9 patients with a mean gestational age of 28.3 weeks (range, 26–31w) and mean birth weight of 1090g (range, 860–1330g) were included in the study. They all had Zone 1 or posterior Zone 2 plus disease staging between severe 3 and 4a. Twelve eyes were treatment naive at the beginning. The mean follow-up was 19.5±11.8 months (range, 11–40 months). The disease regressed totally in 6 eyes (40%), stayed stable as stage 4a in 1 eye (6.7%), progressed to and stabilized at stage 4a in 3 eyes (20%) and progressed to stage 5 in 3 eyes (20%) within 7–10 days. Two eyes (13.3%) developed hypotony and cataract.ConclusionThe association of IVB and laser ablation might decrease the progression rate in severe AP-ROP. Prompt regression of iris neovascularization encourages its use in cases with pupillary rigidity to allow for laser treatment. When used as a salvage therapy it may not change the overall result dramatically
Trabeculectomy with large area mitomycin-C application as a first-line treatment in advanced glaucoma:retrospective review
<b>AIM:</b>To evaluate the outcomes of trabeculectomy with large area mitomycin-C (MMC) application as a first line treatment in advanced glaucoma.<b>METHODS:</b>The records of 55 patients with severe visual field defects undergoing trabeculectomy were retrospectively reviewed. The patients were classified as first-line therapy to either early trabeculectomy (initial trabeculectomy-Group 1) or long term medical therapy followed by trabeculectomy (primary trabeculectomy-Group 2). Trabeculectomy was performed with large-area MMC application. Intraocular pressure (IOP) values, visual acuities, mean deviations, morphology and function of the blebs, necessity for anti-glaucomatous medications and surgical complications were reported.<b>RESULTS:</b>There were 20 eyes of 18 patients in Group 1 and 37 eyes of 37 patients in Group 2<b>.</b> The mean preoperative IOPs in Groups 1 and 2 were 40.2±10.0mmHg (27-68mmHg) and 29.0±4.4mmHg (21-41mmHg), respectively (<i>P</i>=0.001). Average preoperative mean deviations (MD) in Groups 1 and 2 were 17.4±2.8dB (13.3-23dB) and 17.9±2.4 dB (13.7-23.2dB), respectively (<i>P</i>=0.441). Postoperative IOPs significantly decreased and were comparable in both Groups. The mean number of medications was significantly higher in Group 2 (<i>P</i>=0.005)<i><b>.</b></i> No cystic bleb formation was observed in Group 1, whereas 4 patients from Group 2 (10.8 %) developed cystic bleb (<i>P</i>=0.040). No visually devastating complication has occurred in both Groups.<b>CONCLUSION:</b>Initial trabeculectomy with large area MMC application might be applied in patients with advanced glaucoma with low complication rates. Long-term topically applied anti-glaucomatous medications seem to increase the risk of cystic bleb formation
