“…Corneal decompansation following placement of drainage implants has been reported up to 27% of eyes. [17][18][19][20][21] In our patients corneal decompansation was not a major contributing factor for loss of vision and tube failure.…”

Aims To evaluate the surgical success results of Ahmed glaucoma valve (AGV) and Molteno single-plate implant (MSPI) in cases of neovascular glaucoma (NVG). Methods Between May 1997 and May 2002, 38 of 38 NVG patients that underwent implantation of AGV and 27 eyes of 27 NVG patients that underwent MSPI (a total 65 eyes of 65 patients) included to the study. Results The cumulative probabilities of success were 63.2% at 1 year, 56.2% at 2 years, 43.2% at 3 years, 37.8% at 4 years, and 25.2% at 5 years in AGV group whereas the cumulative probabilities of success were 37.0% at 1 year, 29.6% at 2 years, 29.6% at 3 years, 29.6% at 4 years, and 29.6% at 5 years in MSPI group (P ¼ 0.141). Preoperative visual acuity o2/200 (P ¼ 0.003), diagnosis of diabetes mellitius (P ¼ 0.050), and preoperative IOP Z35 mmHg (P ¼ 0.038) were found to be poor prognostic factors for surgical success. Conclusions Both AGV and single plate MSPI were successful for early and intermediate-term of IOP control but in long term both implants were failed to achieve control of IOP in patients with NVG.

“…While it is effective in controlling intra-ocular pressure (IOP) [2,4,5], trabeculectomy can lead to potentially sight-threatening complications [6,7]. In an attempt to lower the incidence of such complications, other techniques based on the concept of nonperforating filtration surgery (NPFS), were developed.…”

The efficacy and safety of a newly designed Ex-PRESS X-200 drainage device for the surgical treatment of glaucoma was evaluated. A clinical, prospective, monocentric, non-randomised, unmasked study on patients with medically uncontrolled glaucoma was performed. A superficial scleral flap was created. A posterior deep sclerectomy (DS) was dissected without opening the Schlemm's canal and an Ex-PRESS X-200 device was inserted under the scleral flap into the anterior chamber to drain aqueous humour into the intrascleral space. Biomicroscopy, best-corrected visual acuity (BCVA), applanation intra-ocular pressure (IOP) measurements, and fundus examination were performed before surgery, on the first day, the first week, and 1, 2, 3, 6, 12 and 18 months after surgery. The mean follow-up was 18.6 ± 2.4 months (mean ± SD) for the 26 eyes that were treated with the Ex-PRESS X-200 device. Preoperatively, the mean BCVA was 0.6 ± 0.3, the mean IOP was 22.0 ± 5.1 mmHg, and the mean number of medications per patients was 2.8 ± 0.8. Eighteen months after surgery the mean BCVA was 0.5 ± 0.4, the mean IOP was reduced to 12.0 ± 3.9 mmHg, and the mean number of medications per patient was 0.6 ± 1.2. Eighty-five percent of patients achieved an IOP \ 18 mmHg with or without medication and 69% without medication. Post-operative complications were hyphaema (15%), Seidel (15%), encysted blebs (54%) and bleb fibrosis in 8% of patients. Mitomycin C(MMC) was administered to 15 patients (58%) with needling being performed on 10 (38%) of these patients. Mid-term results of DS with the Ex-PRESS X-200 implant demonstrated its efficacy in controlling IOP with few post-operative complications in difficult eyes with an increased risk of surgery failure.

RESUMENObjetivos: Analizar los resultados a medio plazo de los dispositivos de drenaje para glaucoma (DDG) en cuanto a control de la presión intraocular (PIO), del glaucoma y del mantenimiento de la visión preoperatoria. Métodos: Estudio de cohortes retrospectivo de 86 ojos de 77 pacientes en los que se ha implantado un DDG. Se ha empleado estadística descriptiva y aná-lisis de supervivencia. Resultados: Se han considerado como éxito 53 ojos (61,6%), completo (sin tratamiento) en 34 ojos (39,5%); y relativo (con tratamiento) en 19 ojos (22,1%). Las causas de fracaso han sido: mal control de la PIO en 13 ojos -(15,1%), y complicaciones en 20 ojos (23,2%) con reducción severa o pér-dida de visión (extrusión del reservorio, hemorragia supracoroidea, desprendimiento de retina). Se ha obtenido control de la PIO en 66 ojos (76,7%), en 47 de ellos sin tratamiento (54,6%), aunque 13 de estos han sido fracasos por complicaciones. A pesar del control de la PIO, en siete ojos (8,1%) se ha observado progresión del glaucoma. En cuanto a la visión, en 46 ojos (53,5%) se ha mantenido estable y en 40 ha disminuido 3 o más líneas (46,5%), siendo la causa más frecuente la descompensación cor-ARTÍCULO ORIGINAL ABSTRACT 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.
