No glaucoma, a elevação da pressão intraocular (PIO) é considerada o principal fator de risco modificável para o desenvolvimento e a progressão da neuropatia óptica glaucomatosa.(,) A PIO se eleva a partir de uma obstrução progressiva na via de drenagem convencional do humor aquoso, a via trabecular.(-) O humor aquoso, produzido nos processos ciliares no corpo ciliar, é lançado na câmara posterior. A secreção de humor aquoso segue um ritmo circadiano variando de cerca de 2,5 a 3,0µL por minuto, […]

ABSTRACT Throughout life, the lens produces new fibers arranged concentrically, which increase its anteroposterior diameter and weight, making its nucleus more compact and hardened. Hypermature cataract is an advanced stage of this fiber proliferation, which can trigger a variety of complications. Spontaneous rupture of the anterior lens capsule evolving with anterior displacement of the nucleus is a rare complication, with few cases published in the literature. We describe the case of a 68-year-old female patient, who presented spontaneous rupture of […]
