- W3118202335 abstract "Introduction. Neovascular glaucoma (NVG) is one of the most prognostically unfavorable forms of the glaucomatous process. The leading pathogenetic mechanism for the development of NVH is hypoxia of the inner layers of the retina, leading to the development of endothelial vascular growth factors (VEGF), which induce neovascular proliferation. In the presence of newly formed vessels in the corner of the anterior chamber, the use of traditional surgical methods for treating glaucoma is limited. That is why the search for a new pathogenetically oriented methods for the treatment of NVH is still acute issue in ophthalmology. Purpose. To evaluate the preliminary results of combined treatment, including intraocular introduction of anti-VEGF therapies (ranibizumab) and micropulse cyclophotocoagulation, in patients with secondary neovascular glaucoma. Materials and methods. The study included 15 patients (15 eyes) with secondary neovascular glaucoma. The value of intraocular pressure (IOP) before surgery ranged from 28 to 44 mm Hg. (average 36.3 ± 4.4 mm Hg), the number of hypotensive drops was 3.5 ± 0.5. The combine treat of patients including the intraocular administration of a VEGF inhibitor (ranibizumab) and through 7-14 days transscleral diode-laser cyclophotocoagulation in micropulse mode on the device «Cyclo G6 Glaucoma Laser System» (IRIDEX, USA) with a laser power of 2000 mW, an exposition of 160 s (80 s in each hemisphere) and a duty cycle of 31.3%. Results. All treatment procedures were performed without complications. By 6 months of follow-up, the average IOP level was 26.9 ± 3.3 mm Hg, the number of hypotensive drops was reduced to 2.7 ± 0.7 drugs. By 1 month of observation, a decrease in the number of newly formed vessels of the iris was achived in all patients. According to ultrasound biomicroscopy, the thickness of the ciliary body (CT) before treatment was on average 0.58 ± 0.14 mm. By 6 months of follow-up, no cases of postoperative atrophy of CT was diagnosed, the thickness of the CT was on average 0.53 ± 0.11 mm. According to the data of optical coherence tomography in the angiography mode, in all cases there was a positive dynamic in 1 month after combined treatment - a significant decrease in macular edema, the area of the retinal nonperfusion zone and the number of newly formed vessels. Conclusion. Combined treatment of patients with secondary neovascular glaucoma, including intraocular introduction of anti-VEGF therapies and micropulse cyclophotocoagulation, is an effective and safe method for reducing IOP." @default.
