CHAVIANO LEON, Gelen et al. Baerveldt valve implantation in a case of refractory glaucoma. Rev Cubana Oftalmol [online]. 2020, vol.33, n.4  Epub 08-Feb-2021. ISSN 1561-3070.

A case is presented of a female 52-year-old patient with a history of bronchial asthma, myopia and juvenile glaucoma diagnosed at age 22. Two trabeculectomies were performed on the left eye and one on the right eye. In the year 2008 the patient underwent phacoemulsification surgery plus intraocular lens implantation in both eyes. She attended our service a year ago, reporting progressive vision reduction. Ophthalmological examination revealed best corrected visual acuity of 0.4 and intraocular pressure of 30 and 23.5 mm/Hg for either eye, with maximum tolerated hypotensive therapy. Funduscopy showed advanced glaucomatous damage, greater in the left eye. The treatment option selected was transcleral cyclophotocoagulation in two quadrants of the right eye. At 6 months intraocular pressure was 30 and 18 mm/Hg, and it was decided to implant a Baerveldt valve in the upper temporal quadrant of the right eye. Ophthalmological examination results at 7 days postoperative were intraocular pressure 5 mm/Hg, grade III athalamia and best corrected visual acuity 0.2. The treatment indicated was a cycloplegic mydriatic and topical and systemic anti-inflammatories. Ocular status improvement was achieved at 15 days. Satisfactory visual acuity and an intraocular pressure of 12 mm/Hg were obtained at 3 months postoperative. The Baerveldt drainage device is effective to achieve intraocular pressure reduction in refractory glaucoma.
