There is no proven effective treatment for vision loss in central retinal vein occlusion (CRVO). Bevacizumab has been reported in small series with limited follow-up, to have a positive effect in reducing cystoid macular edema (CME) and improving vision in CRVO.
To report long-term results with the use of bevacizumab in CRVO.
Prospective interventional case series included 15 patients, serially evaluated with best corrected visual acuity (BCVA), optical coherence tomography (OCT), fluorescein angiography, and tonometry. Results were statistically analyzed.
Mean follow-up was 12 +/- 3.6 months (range, 6-18 months); mean number of injections was 2.2 (range, 1-4) per patient. Statistically significant reduction of macular thickness (P < 0.001) was seen at six weeks (mean, 346 mu); three months (mean, 353 mu); six months (mean, 348 mu); and final follow-up (mean, 342 mu). Significant BCVA improvement was seen at six weeks (mean, 0.27 logMAR), three months (mean, 0.3 logMAR), three months (0.15 logMAR), and final follow-up (mean, 0.21 logMAR) (P = 0.009). Also, 73.3% patients had BCVA improvement at the last follow-up.
Intravitreal bevacizumab is an effective treatment option for CME in CRVO patients. Reinjections at appropriate timing, based on the OCT findings, are important for better visual outcome.
[Show abstract][Hide abstract] ABSTRACT: The present study was undertaken to compare the pterygium recurrence rates after treatment with two different concentrations of topical bevacizumab in those who had undergone a primary pterygium excision. The 90 patients who underwent pterygium excision were enrolled in this prospective, placebo-controlled double-blinded interventional case series. The participants were randomly categorized into 3 groups each consisting of 30 subjects. 24 h after surgery, Group II and Group III received a total of 5 and 10 mg/mL dose of topical bevacizumab, respectively; whereas patients in Group I were administered only a placebo starting a day after surgery. Participants were instructed to instill their topical medicines 4 times a day for 1 week. The patients were examined for pterygium recurrence and complications at postoperative 1, 7, and 14 days as well as each month during the following year. Pterygia recurred in 14 patients (46.7 %) in Group I and in 4 patients (13.3 %) in Group II. No recurrence was observed in Group III during the follow-up period. The Kaplan-Meier survival analysis disclosed a significantly better outcome for those who had been treated with 10 mg/mL concentrations of bevacizumab (Mantel-Cox log rank analysis, P < 0.001). The mean recurrence time was not significantly different between Group I and Group II. No ocular or systemic complication developed till the end of follow-up. Thus, 10 mg/mL concentration of topical bevacizumab was more efficacious than 5 mg/mL dose in preventing pterygium recurrence.
