Egorova E.V., Lubimova T.S., Milingert A.V., Opletina A.V. CHANGES OF ANATOMO-TOPOGRAPHIC EYE PARAMETERS IN CASES OF MIXED GLAUCOMA AFTER LASER IRIDECTOMYThe examination was performed in 146 eyes (146 patients) with the first mixed glaucoma. The narrow anterior chamber angle with segmental its closing was revealed in all cases and was accompanied with the anterior chamber depth decreasing and the displacement of irido-lens diaphragm forward due to increasing lens thickness. The anterior chamber depth remained shallow after laser iridectomy in 86 eyes out off 146 (35.8%) and it was accompanied with the small opening of the anterior chamber angle(7.2 -11. degrees). The absence of sufficient efficacy of laser iridectomy was due to lens component significance in mechanism of mixed glaucoma.Key words: combined form of primary open-angle glaucoma, laser iridectomy, shallow anterior chamber, lens-iris diaphragm, anterior chamber angle.
