MUNAYCO-GUILLEN, Fernando et al. Placement of Ahmed Valve through the pars plana for the management of refractory uveitic glaucoma. Acta méd. Peru [online]. 2018, vol.35, n.3, pp.180-183. ISSN 1728-5917.

Uveitis is the third preventable cause of blindness, and uveitic glaucoma is one of its complications. We present the case of a 25-year old female patient who underwent an extracapsular lens excision and AO trabeculectomy, and afterwards bilateral cyclocryotherapy was performed. The underlying inflammatory condition was controlled, and the intraocular pressure (IOP) in the right eye was also controlled for seven years, although she later lost sight (pthisis bulbi). The left eye remained in a stable condition for 15 years, but afterwards it developed 50 mm Hg IOP, so an Ahmed Valve through the pars plana was placed, after having performed a vitrectomy because of the anatomic alterations in the anterior segment. The IOP got controlled and 20/70 vision using glasses was attained, without the use of an ocular antihypertensive compound. Adequate management of the underlying disease and the use of valve drainage systems constitute the best choice for the management of uveitic glaucoma. A good approach option is placing the device through the pars plana, after having performed a vitrectomy.
