Топография вновь созданных путей оттока при антиглаукомных операциях неоваскулярной глаукомы по данным ультразвуковой биомикроскопии

PURPOSE: The study of UBM capacity in drainage structures control after surgical treatment of neovascular glaucoma. METHODS: The study included 80 patients (80 eyes) with neovascular glaucoma. The mean age of the patients was 60.7±1.9. All patients were divided into two groups depending on the surgical technique: group I (main group) included 40 patients after a deep sclerectomy with xenocollagen drainage implantation (DSE with XDI), group II (control group) - 40 patients after standard deep sclerectomy (DSE). All study subjects underwent standard ophthalmological examination as well as ultrasound biomicroscopy (UBM) (“Paradigm Model P60™ UBM”, USA). The following parameters: filtration bleb - height, area, volume; scleral flap - thickness; intracleral cavity - height, area, volume and anterior chamber depth, anterior chamber angle were measured with the help of ultrasound biomicroscopy. RESULTS: Ultrasound biomicroscopic study helped identify the morphological components of each structure respon sible for postoperative drainage function of the eye after deep sclerectomy with implantation of xenocollagenic drainage in patients with neovascular glaucoma. UBM data research of the anterior segment of the eye in early and long-term follow-up revealed that the proposed modified method of deep sclerectomy with xenocollagen drainage implantation allows forming new constructed ways for intraocular fluid outflow from the anterior chamber in supraciliar, sub-Tenon’s space and subconjuctival spaces. This leads to unobstructed filtration of intraocular fluid and helps prevent scarring of the operation zone. CONCLUSION: Using the ultrasound biomicroscopy in patients with neovascular glaucoma allows monitoring the condition of the drainage system of the eye in the postoperative period in order to ensure the prevention of the postoperative hypertension.
