[Clinical value of ab-interno trabecular surgery in the management of glaucoma].

Ab-interno trabecular surgery does not damage sclera and conjunctiva in glaucoma patients and does not prejudice subsequent anti-glaucomatous filtration or drainage device surgery. As only trabecular resistance is surgically modified, the level of intraocular pressure (IOP) can usually not be reduced in the lower teens. Consequently, incisional ab-interno trabecular surgery is a valuable option in early glaucoma stages with moderate IOP elevation, especially in combination with cataract surgery. Ab-interno trabecular surgery is an insufficient surgical tool in normal pressure glaucoma, but also in glaucoma patients with very high IOP peaks. Georg Thieme Verlag KG Stuttgart · New York.
