Abstract:AIM:To evaluate the clinical curative effect of intravitreal Avastin injection for the treatment of neovascular glaucoma. METHODS:There were 23 neovascular glaucoma patients(23 eyes) whose visual acuity was higher than counting fingers treated in our hospital from January 2007 to October 2011. After intravitreal Avastin injection, the change of iris neovessels was observed. When the neovessels subsided in 3-7 days, the anti-glaucoma operation was performed. The intraocular pressure, visual acuity, change of neovessels, inflammatory reaction, complications were observed and followed up 12-24months. RESULTS:In the 23 eyes, there were 21 eyes that iris neovessels subsided in 3-5 days after injection, the effective rate was 91.30%. There were 2 eyes that iris neovessels thinned in 5 days, atrophied in 7 days, and subsided in 2 weeks. The difference of intraocular pressure was less than 2mmHg before and after the Avastin injection. There were no complications and adverse reaction after Avastin injected in 23 eyes, then performed compound trabeculectomy. In the following up days of 12-24 months, there were 18 eyes intraocular pressure in normal range without anti-glaucoma medicine; there were 3 eyes intraocular pressure below 21mmHg adding 2 kinds of anti-glaucoma medicine and 2 eyes intraocular pressure below 21mmHg adding 3 kinds of anti-glaucoma medicine. CONCLUSION:Intravitreal Avastin injection can subside or atrophy the neovessels of neovascular glaucoma, then filtered operation were performed on patients, which avoids intra- or postoperative hemorrhage, destructive operation and preserves better visual acuity and controls intraocular pressure. The complications were treated postoperatively and visual function was protected.
