Fine Structural Evaluation of the Iris After Unilateral Treatment With Latanoprost in Patients Undergoing Bilateral Trabeculectomy (The Mainz II Stud…
2003
Objective To investigate by masked electron microscopy whether 6 months of topical latanoprost caused pathological changes in the peripheral iris of patients with glaucoma. Methods Seventeen patients with bilateral primary open-angle glaucoma requiring trabeculectomy were recruited for this study. The iridectomy taken during surgery on the first eye served as a control. The second test eye was treated topically with latanoprost for 6 months before its trabeculectomy. Fourteen patients completed the treatment arm of the study, and 1 of these underwent marked color change. As a result, 31 iridectomy specimens were fixed, coded, and evaluated. Results The specimens were evaluated for evidence …
Clinical outcomes after implantation of a posterior chamber collagen copolymer phakic intraocular lens with a central hole for myopic correction.
2013
Purpose To evaluate the efficacy, predictability, safety, and stability of a new-model posterior chamber Implantable Collamer Lens phakic intraocular lens (pIOL) (V4c Visian) to correct myopia. Setting Private practice, Oviedo, Spain. Design Case series. Methods This study enrolled patients who had implantation of a new pIOL design with a central hole for more natural aqueous flow, eliminating the need for neodymium:YAG iridotomy or peripheral iridectomy. The uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refractive error, intraocular pressure (IOP), endothelial cell count, central vault, and adverse events were evaluated 6 months postoperatively. Results The study enroll…
Latanoprost-induced iris darkening: a morphometric study of human peripheral iridectomies.
2003
Abstract Purpose. This microscopic study was undertaken to compare the melanocytes of peripheral iridectomy specimens from two eyes that had latanoprost-induced iris darkening (LIID) with iridectomies taken from the fellow untreated eyes. Methods. The two patients in this study were the ones who underwent LIID in the latanoprost treated eye from a series of 17 patients requiring bilateral trabeculectomy. The first trabeculectomy procedure provided a control peripheral iridectomy for each patient, whereas the second eye was treated with once daily 50 μg ml−1 latanoprost drops for 6 months. The four peripheral iridectomy specimens from the two LIID patients were subjected to quantitative morp…
