Secondary traumatic aniridic glaucoma: pathogenesis and treatment modalities

Ocular hypertension resulting from eye injuries occurs in 0.78–6.2%. Penetrating eye injuries rank first (22.5%), and blunt eye traumas rank second (7.65%). This paper addresses recent data on various surgical techniques for secondary traumatic aniridic glaucoma, their pros, and cons. When selecting a surgical technique, a differentiated approach should be followed depending on traumatic lesions of the anterior segment and hydrodynamics. Sometimes, implantation of a prosthetic iris device with an intraocular lens (to close iris defect and restore the diaphragmic function of the iris) triggers the onset of secondary glaucoma after iris injury. In uncontrolled intraocular pressure in the early postoperative period and preserved at least one-third of the iris, a non-penetrating deep sclerectomy can be performed. In extensive tissue damage (less than one-third of the iris is preserved), implantation of glaucoma drainage devices is a pathogenetically oriented strategy. Keywords: traumatic glaucoma, aniridia, secondary glaucoma, glaucoma surgery, prosthetic iris device with an intraocular lens.
