[Glaucoma drainage device obstruction].

PURPOSE: To determine the pathophysiology and to discuss possible solutions for tube obstruction since this is a frequent complication in glaucoma drainage device surgery. MATERIAL AND METHODS: 81 eyes with a glaucoma drainage device (GDD) fitted by our Department during the last twelve years (1991-2002) were retrospectively reviewed and eleven cases of tube obstruction were detected. The treatments included Nd-Yag laser, anterior vitrectomy, blood clot removal and intracamerular rTPA. RESULTS: The obstruction was proximal in ten cases and distal in one. Of the former, the obstruction was caused by a blood clot in six cases, by vitreous in three cases and by a fibrinous membrane in one case. The nature of the distal obstruction was not determined. One case of vitreous obstruction occurred after a posterior capsulotomy with Nd-Yag laser two years after positioning the GDD. Complete success was achieved in five cases, and partial success in three where antiglaucoma therapy had to be maintained postoperatively. Complete failure was found in the other three cases. CONCLUSIONS: The material which most frequently caused the tube obstruction was blood and although in some cases this may resolve spontaneously, clot removal with forceps or rTPA intracameral injection may be helpful. In vitreous obstruction, Nd-Yag laser may temporariril clear the tube, but extensive anterior vitrectomy is required to maintain long-term permeability. We suggest carrying out a small posterior capsulotomy in pseudophakic patients with a GDD.

[Management of encapsulated blebs after glaucoma drainage device surgery].

PURPOSE: We analyse the different options for the management of encapsulated blebs after glaucoma drainage device surgery, specially subconjunctival 5-fluouracil (5-FU) injections with or without associated needling. METHODS: Retrospective review of 20 eyes with encapsulated blebs following glaucoma drainage device surgery. All of the eyes received topical corticosteroids associated to digital massage. Subconjunctival 5-FU was necessary in 10 eyes, associated to needling of the bleb in 5 of them and to capsule excision in 2. RESULTS: Fifteen eyes were considered successes (complete in 10 eyes and uncomplete in 5). Eight of them had been treated with 5-FU (80% success in the 5-FU treated eyes group), associated to needling and/or capsule excision in 4 of them. The remaining 7 eyes were only treated conservatively (70% success with corticoid therapy and digital pressure). CONCLUSIONS: We have obtained in our study very good results using subconjunctival 5-FU injections, associated in complicated or refractory cases to needling revision, in eyes with encapsulated blebs after glaucoma drainage device surgery, with no major complications (Arch Soc Esp Oftalmol 2002; 77: 429-434).

[Incidence of encapsulated bleb after filtering surgery].

OBJECTIVE: To determine the incidence of encapsulated bleb (EB) after filtering surgery, and the risk factors for the development of this complication, especially those related with the surgical procedure. METHODS: Ninety eyes that were submitted to trabeculectomy were prospectively studied. Lens extraction was associated in 56 eyes (62.9%). All patients were followed up for at least 3 months. RESULTS: There were clinical characteristics of encapsulation in 29 eyes (32.3%) and EB with a peak IOP of 25 mmHg or higher in 14 eyes (15.7%). The incidence of EB formation was 20.5% in men and 11.8% in women (p.044). The incidence of EB was higher in the trabeculectomy group alone (24.2%) than in the group in which it was associated to cataract surgery (10.5%) (p.003). There were clinical characteristics of encapsulation in 40.7% of primary open angle glaucoma (p.041). EB was significantly associated with an increased failure rate (21.4%) when compared to normal blebs (5.55% failure rate) (p<.001). CONCLUSIONS: The encapsulated bleb is significantly more frequent in the male gender and thick conjunctivas and in trabeculectomy alone versus trabeculectomy associated to cataract surgery. It means a significantly greater risk of failure after surgery in the short term.

[Congenital hypertrophy of retinal pigment epithelium in familial colonic polyposis. Study of a family].

In the last years the relationship between congenital hypertrophy of retinal pigment epithelium (CHPRE) and familial adenomatous polyposis (FAP) has been described. It has been said that ophthalmoscopy would be a good screening method for following up the relatives of patients with FAP. We present an ophthalmoscopic study of 14 member of a family with FAP. Four members with FAP were operated on in our department. Only a six years-old child, to this date without FAP, presented CHPRE. We review the relationship between FAP and CHPRE, and emphasize the importance of follow-up in FAP specially when CHPRE is present.
