1/9. Accelerated ocular neovascularisation in diabetics following posterior chamber lens implantation.Two well controlled non-insulin dependent diabetics with background retinopathy underwent endocapsular lens extraction with in-the-bag posterior chamber implantation. In the postoperative period rubeosis iridis set in abruptly. The fellow eyes showed no progression of retinopathy and the diabetic status showed no deterioration. The cause of neovascularisation and the role of intra- versus extracapsular extraction with implantation are discussed.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/9. Rubeosis capsulare.Two patients with diabetes had extracapsular cataract extraction with intraocular lens (IOL) implantation. Both developed rubeosis iridis and neovascularization within the lens capsule supporting the IOL, a condition we have termed rubeosis capsular. argon laser treatment was ineffective in both patients. One patient was successfully treated by virectomy with endophotocoagulation. The other patient had a vitrectomy which was followed by a fibrinoid reaction, continued inflammation, rubeosis, and phthisis bulbi.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
3/9. Neovascular glaucoma following neodymium-YAG laser posterior capsulotomy.iris neovascularization and neovascular glaucoma were diagnosed in three diabetic patients following neodymium-YAG laser posterior capsulotomy. Each of the patients had previously undergone an uncomplicated extracapsular cataract extraction with insertion of a posterior chamber lens implant. These occurrences are consistent with the hypothesis that the posterior lens capsule may serve as a protective barrier to a diffusible vasoproliferative factor from the vitreous or retina. Both the beneficial optical effects and the potential adverse effects should be carefully considered prior to performing neodymium-YAG laser posterior capsulotomy in diabetic patients or other patients with ischemia in the fundus. Following neodymium-YAG laser posterior capsulotomy, these eyes should be closely followed up for signs of neovascularization and possible panretinal photocoagulation.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
4/9. Effects of extracapsular cataract extraction with posterior chamber lens implantation on the development of neovascular glaucoma in diabetics.We retrospectively reviewed four cases of extracapsular cataract extraction with implantation of a posterior chamber intraocular lens into diabetics. All four developed postoperative iris rubeosis and neovascular glaucoma; three of the cases had a poor visual outcome. The implant surgeon must show discretion in deciding to implant an intraocular lens in diabetics whether or not they are noninsulin dependent and well controlled, understanding the serious complications that may result from progression of diabetic retinopathy and rubeosis iridis.- - - - - - - - - - ranking = 2.5keywords = extraction (Clic here for more details about this article) |
5/9. Intraocular hemorrhage from wound neovascularization years after anterior segment surgery (Swan syndrome).At the Mayo Clinic from 1972 to 1986, 15 patients (17 eyes) had intraocular hemorrhage due to neovascularization of the stromal wound years after anterior segment surgery (Swan syndrome). Months to years after surgery patients complained of low-grade blurring that was painless and transient. The hemorrhage was seen after intracapsular cataract extraction, and one third of the patients had had an intraocular lens implant. Of the 15 patients 14 were referred, 6 for vitreous hemorrhage, 5 for recurrent hyphema, 2 for amaurosis fugax and 1 for recurrent uveitis. The average time between surgery and presentation was 4 years. The initial visual acuity was better than 20/40 in 15 eyes (extremes 20/20 and hand movement), and intraocular pressure was elevated above 30 mm Hg in 2 eyes. Treatment included periodic observation (in 10 eyes), goniophotocoagulation (in 7) and limbal cryopexy (in 3). After a mean follow-up period of 3 years all 17 eyes showed normal acuity and intraocular pressure. No patient had intractable glaucoma or phthisis.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
6/9. Subretinal neovascularization in a pseudophakic eye treated with krypton laser photocoagulation. A clinicopathologic case report.A 76-year-old myopic woman who had undergone bilateral extracapsular cataract extractions and received posterior intraocular lens implants underwent two sessions of krypton laser photocoagulation for subretinal neovascularization secondary to age-related macular degeneration in her right eye. The patient expired and histopathologic examination of her treated eye showed a posterior chamber intraocular lens with both haptics in the ciliary sulcus, areas of macular degeneration, evidence of krypton laser photocoagulation including a full-thickness retinal scar, and an area of clinically unsuspected subretinal neovascularization.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
7/9. Extended-wear aphakic soft contact lenses after penetrating keratoplasty.Seven patients undergoing aphakic keratoplasty or combined keratoplasty and cataract extraction were fitted with a single type of high-water-content, extended-wear, aphakic soft contact lens (Permalens). Six patients were fitted early after keratoplasty, ie, before the removal of the sutures and while they were still receiving corticosteroid drops (1% prednisolone acetate). The patients were followed up at close intervals with high-magnification serial corneal photography. Complications of extended wear included superficial neovascularization, punctate epithelial keratitis, and variable visual acuity. Our results suggest that although extended-wear aphakic soft contact lenses may be an acceptance form of visual rehabilitation in selected patients who undergo transplantation, they are frequently problematic. In addition, fitting of these lenses should be withheld until after the removal of the sutures, and patients should be followed up at closer intervals than the patients with extended-wear aphakic soft contact lenses who have not undergone keratoplasty.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
8/9. Choroidoretinal neovascularisation following radon seed treatment of retinoblastoma in two patients.Two patients who developed localised radiation retinopathy many years after brachytherapy for retinoblastoma are described. In both patients extracapsular cataract extraction and YAG laser capsulotomy were followed by preretinal and vitreous haemorrhage and in one patient there was deterioration of existing radiation retinopathy with macular oedema. Premacular and vitreous haemorrhage occurred from focal, preretinal neovascular membranes which appeared to originate from residual choroidal vascular radicals. Laser photocoagulation was successful in ablating preretinal neovascular membranes and limiting the extent of macular oedema from incompetent retinal capillaries adjacent to the atrophic macular scars.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
9/9. Anterior hyaloidal fibrovascular proliferation after extracapsular cataract extraction in diabetic eyes.Four patients with proliferative diabetic retinopathy developed anterior hyaloidal fibrovascular proliferation after extracapsular cataract extraction and posterior chamber lens implantation. This complication of cataract extraction has been described after vitrectomy in diabetic eyes. risk factors for this entity after extracapsular cataract extraction include proliferative diabetic retinopathy, iris neovascularization, and anterior ischemic retina. Anterior hyaloidal fibrovascular proliferation was observed an average of 12 months postoperatively and affected vision in one of four patients. No progression was seen within an average of six months of follow-up, and no complications such as traction retinal detachment and vitreous hemorrhage developed.- - - - - - - - - - ranking = 3.5keywords = extraction (Clic here for more details about this article) |
