Angle-closure glaucoma after piggyback intraocular lens implantation.

PURPOSE: To report a case of angle closure glaucoma after piggyback intraocular lens implantation and its treatment. METHODS: The authors present the case of a 75-year-old woman who was seen in the emergency department with angle closure glaucoma. Two years before she had undergone piggyback intraocular lens (IOL) implantation in order to correct a refractive error after cataract surgery. Ultrasound biomicroscopy revealed a closed angle with synechiae in 360 degrees as well as the presence of two IOLs: one in the capsular bag and the other in the ciliary sulcus. Extraction of the anterior IOL was precluded due to the poor endothelial count. Peripheral iridotomy and trabeculectomy were ineffective to lower the intraocular pressure (IOP); the authors decided to implant with an Ahmed valve and to place the valve's tube between the two IOLs to protect the endothelium. RESULTS: After Ahmed valve implantation, IOP maintains stable around 10-12 mmHg without medical treatment. CONCLUSIONS: Ahmed valve implantation is a good option in angle closure glaucoma due to piggyback. The placement of the valve's tube between the two IOLs is a good option to protect corneal endothelium.

Ocular inflammatory signs observed in a cohort of Spanish patients with Behçet disease and ocular inflammation.

PURPOSE: To study the clinical characteristics of a cohort of Spanish patients diagnosed with Behcet disease and who also presented ocular inflammation. METHODS: Thirty cases of Behçet disease were studied retrospectively. The authors studied age distribution, distribution by sex, clinical course, laterality, type of uveitis, secondary glaucoma, corneal involvement, hypopyon, iris-lens synechiae, secondary cataract, cystoid macular edema (CME), and papillitis (optic neuritis). RESULTS: Fourteen of the patients were men and 16 were women (ratio 0.875:1). The mean age of the patients was 35.24 years (+/-10.917; 21-61 years). In 23 patients, the disease course was recurrent. In 9 patients, the disease manifested unilaterally. In 5 patients showing unilateral onset, the contralateral eye became affected. In 2 of the 30 patients, uveitis exclusively affected the anterior segment. In 8 patients, uveitis was solely posterior. There was one case of intermediate uveitis. The remaining 19 patients showed panuveitis. Three had focal chorioretinitis. One had diffuse chorioretinitis. Fifteen showed signs of diffuse vasculitis. Eight patients showed focal vasculitis. CONCLUSIONS: Women were slightly more affected than men, although the authors found no significant correlation between sex and the clinical variables examined. Apart from one unexpected case of intermediate uveitis, the observations are similar to those reported for other patient series.

[Photodynamic therapy in angioid streaks]. / Terapia fotodinámica en estrías angioides.

OBJECTIVE: To evaluate the efficacy and safety of photodynamic therapy in choroidal neovascularization associated with angioid streaks. METHODS: We performed a retrospective study of eleven eyes (eight patients) with subfoveal, juxtafoveal or extrafoveal neovascularization, which received at least one session of photodynamic therapy. Treatment efficacy was evaluated by visual acuity (VA) testing, color photography and fluorescein angiography. The mean follow-up was 13.2 months. RESULTS: Ten eyes presented subfoveal neovascularization, one eye presented juxtafoveal and another eye extrafoveal neovascularization. VA was unchanged in two patients, increased in one patient, and decreased in eight patients following photodynamic therapy. Nine eyes presented conversion to a fibrotic disciform lesion, whereas leakage persisted in two eyes after one session of photodynamic therapy. Recurrence of choroidal neovascularization appeared in three eyes. CONCLUSIONS: Photodynamic therapy in choroidal neovascularization related to angioid streaks does not appear to alter the course of this disease, but it does slow its progression.
