Efficiency of Xalatamax in treating the initial stage of primary open-angle glaucoma
PURPOSE: To evaluate the efficacy of latanoprost 0.005% treatment for patients with primary open-angle glaucoma during follow-up from the positions of individual IOP level achievement, eye hemodynamics improvement and visual functions stabilization. METHODS: The study included 186 patients with an initial stage of primary open-angle glaucoma (186 eyes) with pseudoexfoliative syndrome. The average age of the patients was 60.4±0.6 years. RESULTS: Individual IOP level was achieved in 119 patients with initial stage primary open-angle glaucoma (119 eyes) - 64% of cases. After latanoprost 0.005% instillation the average IOP value in patients with glaucoma decreased from 22.4±0.7 mm Hg to 15.1±0.7 mm Hg, totaling a decrease of 7.3 mmHg (32.6%) from baseline IOP and fitting into the tolerable IOP green zone (t=7.4; p=0.001). In 67 patients with glaucoma (67 eyes) required a combined drug treatment to reach a needed IOP level. Ophtalmosphygmography showed a significant improvement of hemodynamic parameters of the eyes after intraocular pressure reduction to tolerable IOP level (p=0.001). CONCLUSION: Ophthalmosphygmography parameters (intraocular vessels elasticity index, eye blood supply adequacy index) can be used as hemodynamic criteria in evaluating the effectiveness of primary open-angle glaucoma patients treatment. Glaucoma process stabilization was observed in 95.8% of patients with initial stage of primary open-angle glaucoma after IOP reduction to the individual tolerance level due to latanoprost 0.005% instillation.
