Resumen
MERINO-DE-PALACIOS, C. et al. Intermediate-term outcome of glaucoma drainage devices. Arch Soc Esp Oftalmol [online]. 2008, vol.83, n.1, pp.15-22. ISSN 0365-6691.
Objective: To study the intermediate-term results of glaucoma drainage devices (DDG) with respect to control of intraocular pressure (IOP), control of glaucoma, and maintenance of pre-operative visual acuity. Methods: This was a retrospective cohort study of 86 eyes in 77 patients in whom a DDG was implanted, using descriptive statistics and survival analysis. Results: Success was achieved in 53 eyes (61.6%), complete (without treatment) in 34 eyes (39.5%) and qualified (needing treatment) in 19 eyes (22.1%). In the 33 eyes where the DDG treatment was unsuccessful, poor IOP control occurred in 13 eyes - (15.1%), and complications occurred in 20 eyes (23.2%) resulting in a severe reduction or loss of visual acuity (plate exposure, suprachoroidal hemorrhage, retinal detachment). IOP control was obtained in 66 eyes (76.7%), 47 of them without treatment (54.6%), although on 13 occasions the overall treatment failed due to complications occurring. Despite IOP control, glaucoma progression occurred in 7 eyes (8.1%). Preoperative vision was maintained in 46 eyes (53.5%), but decreased by 3 or more lines in 20 eyes (46.5%); bullous kerathopathy was the most frequent cause of the worsening. Loss of light perception occurred in 21 eyes (24.4%) and 4 eyes (4.6%) were eviscerated. Conclusions: DDG are an effective surgical option for control of IOP when conventional surgery has a poor prognosis, but they are associated with an increased risk of serious complications and loss of visual acuity in a significant proportion of cases.
