Repeat glaucoma surgery: modern view of the problem

Abstract

Glaucoma surgery is the most effective way to achieve target levels of intraocular pressure. However, it has significant advantages and disadvantages. The main disadvantage is the temporary nature of its hypotensive effect. The onset of surgical failure can occur at various times after the intervention. A correct assessment of the operation timing and risk factors for excessive scarring, as well as correct perioperative therapy, can prolong the effectiveness of the surgery and reduce the number of repeat operations.With a wide choice of surgical treatment methods, trabeculectomy remains the most frequently performed intervention. Its effect is better understood and can be considered more controllable. If the surgical treatment of glaucoma is ineffective, it is possible to prescribe a "restart" therapy, activate previously formed outflow tracts, and perform a second intervention. The development of needling technology makes it possible to delay repeat interventions, prolonging the hypotensive effect of the initial operation.
