1/230. Treatment of fibrinous pupillary membrane occlusion following cataract surgery with microruptor laser.A 79-year-old female with rheumatoid arthritis suffered from severe induced iritis with dense fibrinous pupillary membrane occlusion and high intraocular pressure (57 mmHg) following cataract surgery. We used a Nd:YAG laser technique to dissect and move the dense pupillary membrane away and avoid invasive surgical procedures. Postoperatively, we recorded IOP 14 mmHg and visual acuity 20/30.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
2/230. Long-term outcome of aqueous shunt surgery in ten patients with iridocorneal endothelial syndrome.PURPOSE: To report the long-term outcome of ten patients with iridocorneal endothelial (ice) syndrome who underwent aqueous shunt surgery for uncontrolled glaucoma. DESIGN: Noncomparative, retrospective case series. PARTICIPANTS: The authors reviewed charts of ten patients with ice syndrome-related glaucoma who underwent aqueous shunt surgery at one institution between 1987 and 1996. MAIN OUTCOME MEASURES: intraocular pressure (IOP), number of glaucoma medications, and further surgical interventions were measured. RESULTS: With a median follow-up of 55 months, four eyes had adequate IOP control (IOP <21 mm Hg) with one or two medications after the initial aqueous shunt surgery. An additional three eyes achieved adequate IOP control after one or more tube repositionings or revisions of the initial aqueous shunt. In this series, the aqueous shunt surgery most often failed because of blocking of the tube ostium by iris, ice membrane, or membrane-induced tube migration. CONCLUSION: Aqueous shunt surgery appears to be an effective method for IOP lowering in some eyes with ice syndrome-related glaucoma when medical treatment or conventional filtration surgeries fail, but additional glaucoma procedures and/or aqueous shunt revisions and tube repositionings are not uncommon.- - - - - - - - - - ranking = 13.234793574497keywords = eye, ocular (Clic here for more details about this article) |
3/230. Excimer laser photorefractive keratectomy in myopic eyes with corectopia.Corectopia, the eccentric displacement of the pupil, may be associated with other abnormalities such as axial high myopia or ectopia lentis. We report the case of a patient presenting for surgery to correct bilateral myopia of 6.50 diopters (D) associated with corectopia. Excimer laser ablation was decentered and performed on the center of the abnormal pupils. After a 2 year follow-up, best corrected visual acuity was 20/20 with -1.00 D correction in each eye. To our knowledge, this is the first report of excimer laser photorefractive keratectomy for myopia associated with corectopia. The satisfactory results suggest that in abnormally eccentric pupils, excimer laser treatment of myopia may be successful when it is centered on the deviated pupil.- - - - - - - - - - ranking = 20.391322624161keywords = eye (Clic here for more details about this article) |
4/230. Loss of iridolenticular contact in eyes with exfoliation syndrome may protect against glaucoma.PURPOSE: To provide evidence for the hypothesis that dynamic iridolenticular contact predisposes to the development of glaucoma in exfoliation syndrome (XFS). methods: We present four patients with bilateral XFS and unilateral exfoliation glaucoma (XFG) whose normotensive eyes had suffered traumatic loss of dynamic iridolenticular contact. RESULTS: All 4 patients had bilateral XFS and developed XFG only in the untraumatized eyes. One patient had loss of iridolenticular contact in the traumatized eye, two had a nonreactive pupil, and one had had intracapsular cataract extraction at age 28. CONCLUSIONS: Loss of dynamic iridolenticular contact may help to protect against development of glaucoma in eyes with XFS.- - - - - - - - - - ranking = 32.626116198658keywords = eye (Clic here for more details about this article) |
5/230. Cataract surgery combined with implantation of an artificial iris.We describe 6 patients who presented with cataract or aphakia and absent or nonfunctional irides. The etiologies included congenital aniridia, traumatic iris loss, and chronic mydriasis secondary to recurrent herpetic uveitis. In 5 eyes, a prosthetic iris was successfully implanted in combination with small incision cataract surgery. In 2 eyes, a single-piece iris diaphragm and optical lens was implanted. Artificial irides offer a safe alternative for patients who previously had no viable options for iris reconstruction.- - - - - - - - - - ranking = 8.1565290496645keywords = eye (Clic here for more details about this article) |
6/230. Iridocorneal adhesions in patients with the marfan syndrome.marfan syndrome is an autosomal dominant connective tissue disorder characterized by skeletal, cardiovascular, and ocular anomalies. ectopia lentis is the most common ocular manifestation. We report an ocular sign not previously described in marfan syndrome, iridocorneal adhesions secondary to anterior lens subluxation. Three patients with the marfan syndrome had iridocorneal adhesions on slit-lamp examination. One patient developed adhesions following treatment with pilocarpine. She underwent pars plana vitrectomy and lensectomy in both eyes due to progression of the iridocorneal adhesions. Treatment with miotics rotates the lens-iris diaphragm anteriorly and may contribute to the formation of such adhesions. The two other patients remained stable and did not received lensectomy or vitrectomy. Careful slit-lamp examination of the anterior segment should be conducted in patients with dislocated lenses.- - - - - - - - - - ranking = 7.0782645248322keywords = eye, ocular (Clic here for more details about this article) |
7/230. Histopathological findings of X-linked retinoschisis with neovascular glaucoma.BACKGROUND: X-linked retinoschisis (XLRS) is rarely complicated by neovascular glaucoma. Only a few reports of XLRS histopathological findings with neovascular glaucoma have been published. methods: A 41-year-old man with XLRS complicated by neovascular glaucoma in his left eye was examined with electroretinography, B-scan, ultrasound biomicroscopy and computed tomography. He was examined by ophthalmoscopy and fluorescein angiography in the other eye. An enucleation was performed in his left eye due to uncontrollable high intraocular pressure and persistent ocular pain. We examined the enucleated eye histopathologically. RESULTS: Examination of the enucleated eye showed nuclear sclerosis of the lens, pigmented retrolental membrane and retinoschisis which separated the inner layer of the retina and made a large space in the vitreous cavity without any apparent detachment of the outer layers of the retina. Sclerotic vessels were present histopathologically in both the inner and outer layers of the retina. There was a peripheral anterior synechia, ectropion uveae and a fibrovascular membrane, which contained many lumina of neovascularization, indicating marked rubeosis iridis. Small cystic spaces were observed in both the schitic retina in the peripheral region and the foveal schisis at the outer layer of the retina. The photoreceptor cells had become markedly atrophied and multiple regions of calcification were observed. The optic nerve showed severe atrophy with gliosis, but the central retinal artery and vein were still open within the nerve. CONCLUSIONS: These histopathological findings suggest that rubeosis iridis may have developed secondarily to retinal ischemia due to occlusion of the retinal blood vessels.- - - - - - - - - - ranking = 22.391322624161keywords = eye, ocular (Clic here for more details about this article) |
8/230. Laser iridocystotomy for bilateral acute angle-closure glaucoma secondary to iris cysts.PURPOSE: To report laser iridocystotomy for bilateral acute angle-closure glaucoma secondary to peripheral iris cysts. METHOD: Case report. RESULTS: In a 55-year-old man with increased bilateral intraocular pressure, gonioscopy revealed varied angle narrowing. Bilateral angle-closure glaucoma secondary to peripheral iris cysts was diagnosed by ultrasound biomicroscopy. The peripheral iris cysts could not be seen in mydriasis by gonioscopy. Therefore, we decided to perform laser iridocystotomy with argon and Nd:YAG laser. Collapse of the cysts after laser treatment was demonstrated by ultrasound biomicroscopy. At follow-up, 9 months after laser treatment, intraocular pressure had dropped below 20 mm Hg in both eyes without further therapy. The iris cysts did not recur, which was demonstrated by ultrasound biomicroscopy. CONCLUSIONS: Peripheral iris cysts may produce angle closure and may cause secondary angle-closure glaucoma. If transpupillary laser cystotomy is not possible, laser iridocystotomy may produce collapse of the iris cysts and correction of secondary angle closure.- - - - - - - - - - ranking = 6.0782645248322keywords = eye, ocular (Clic here for more details about this article) |
9/230. Latanoprost-induced iris color darkening: a case report with long-term follow-up.PURPOSE: To determine the effect on iris color of discontinuing latanoprost (LP) treatment in a patient with pronounced iris color darkening, and to assess the possible role of sympathetic innervation. methods: In a patient demonstrating pronounced iris color darkening in both eyes after treatment with LP for 6 months, magnified iris color photographs were taken at 3- to 6-month intervals for 5 years after discontinuation of LP treatment. Pupillary testing for sympathetic insufficiency was performed with cocaine 10% or hydroxyamphetamine 1%. RESULTS: The iris color did not appreciably change after discontinuing LP. The cocaine-induced increase in pupillary diameter was considerably greater for the control subject than for the patient who demonstrated the LP-induced color change. CONCLUSIONS: Latanoprost-induced iris color darkening does not appreciably change for several years after discontinuing treatment. Some eyes that show LP-induced darkening may have relative ocular sympathetic insufficiency.- - - - - - - - - - ranking = 9.1565290496645keywords = eye, ocular (Clic here for more details about this article) |
10/230. Hamartomas of the iris and ciliary epithelium in tuberous sclerosis complex.Astrocytic hamartomas of the retina are the principal ocular manifestation of tuberous sclerosis complex. iris abnormalities are rare in tuberous sclerosis complex and include focal areas of stromal depigmentation and atypical colobomata. We describe 2 patients who were found on histopathological examination to have lesions consistent with hamartomas of the iris pigment epithelium and ciliary body epithelium. iris abnormalities, including pupillary irregularities, were noted on clinical examination prior to the development of iris neovascularization in both patients. These observations suggest that iris abnormalities, including atypical colobomas, may be caused by hamartomas of the iris pigment epithelium and ciliary epithelium in some patients with tuberous sclerosis complex. To our knowledge, hamartomas of tissues derived from the anterior part of the neuroectodermal optic cup have not been reported in cases of tuberous sclerosis complex.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
