Chronic fluid misdirection syndrome of aqueous humor after phacoemulsification: diagnosis, treatment and asscociated factors.

The chronic fluid misdirection syndrome of aqueous humor is a rare and serious condition if not treated promptly. The case is presented of a woman attending the emergency department with an intraocular pressure of 43.00mmHg and shallow anterior chamber in her left eye. As clinical history of interest, she had cataract surgery in that eye several weeks before. Following the suspicion of malignant glaucoma, a capsulotomy and iridotomy were performed with an unfavourable outcome. For this reason, it was decided to perform a central vitrectomy, but the patient did not respond to this surgical treatment either. A second surgery was then performed with peripheral vitrectomy, anterior hyaloidectomy, zonulectomy, and iridectomy, obtaining good results. Finally, a decrease in intraocular pressure, and an opening of camerular angle were achieved. Thus, if malignant glaucoma is not resolved in medical consultation with iridotomy and capsulotomy, a vitrectomy, creating a unique chamber that restores the fluid mechanics of the aqueous humor, will be needed.
