The problem of treatment of terminal glaucoma in the world's ophthalmology is still a leading one. Despite advances in the study of the normal physiology of intraocular pressure, in drug treatment of glaucoma due to the appearance of new types of drugs, as well as constantly improving types of surgical and laser interventions, terminal glaucoma is still one of the main causes of irreversible blindness. Drug therapy for terminal glaucoma is often ineffective due to marked dystrophic changes in the drainage system of the eye and the ciliary body, and iris scarring. Such patients are usually treated conservatively until pain syndrome appears, and since drug treatment is ineffective while it is developing, surgical intervention is the only option.
