1/14. Surgical removal of choroidal neovascular membranes after laser photocoagulation for diabetic maculopathy.PURPOSE: Choroidal neovascularisation (CNV) occurs rarely following laser photocoagulation for macular oedema in diabetic retinopathy, and its management is not well established. We report the clinical course and visual outcomes in a series of patients who underwent surgical extraction of the CNV membrane. methods: A retrospective review of 4 cases was carried out. RESULTS: Two women and 2 men, mean age 59.5 (range 58-62) years, were reviewed. The CNV developed 2-24 (mean 11) months after laser coagulation and resulted in decreased visual acuity to between 6/60 and HM. All underwent pars plana vitrectomy, extraction of the CNV membrane and fluid-air exchange. Follow-up ranged between 9 and 48 months. In 2 patients, the vision improved by 4 and 1 Snellen lines respectively and remained stable, in 1 patient it improved by 1 line initially but then regressed to CF, and in 1 patient it remained unchanged. recurrence of CNV occurred in only 1 patient. Histological characteristics were those of CNV without evidence of photoreceptors. CONCLUSIONS: This study shows that surgical removal of post-laser CNV is technically feasible despite the previous laser scars and may have beneficial outcome. This surgical approach may provide a therapeutic option in such patients.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/14. Progressive opacification of hydrophilic acrylic intraocular lenses in diabetic patients.Four patients with diabetes mellitus had cataract extraction with implantation of a hydrophilic acrylic intraocular lens (IOL) (ACRL-C160, Ophthalmed). The IOLs showed progressive and generalized opacification 10 to 20 months after implantation, decreasing visual acuity. All 4 IOLs were removed. By light microscopic examination, the IOL surfaces were wrinkled and encrusted with microspheres. Electron microscopy revealed the material to be crystalline in nature. Energy dispersive x-ray spectrum analysis showed that the deposits were mainly composed of calcium and phosphate.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
3/14. 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) |
4/14. 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) |
5/14. Ectopic hematopoiesis in the human iris.Hematopoietic islands of erythroblastic precursor cells with mitotic activity were found pathologically in the distorted iris of a 35-year-old diabetic male. The eye had been enucleated for absolute hemorrhagic glaucoma occurring secondary to central vein occlusion and complicating previous vitrectomy, repair of retinal detachment and extracapsular cataract extraction.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
6/14. Proliferative retinopathy after 60 years of complication-free diabetes.A patient developed proliferative retinopathy after more than 60 years of complication-free diabetes. This may have been precipitated by an episode of ketosis or by cataract extraction, and emphasizes the need for persistent vigilance in examination for retinopathy.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
7/14. Unplanned extracapsular cataract extraction in postvitrectomy eyes.A 70-year-old man, a 59-year-old woman, and a 57-year-old woman underwent pars plana vitrectomy. In all three cases, cataracts developed in the eyes that had been operated on. During cataract extraction, which included massage of the globe after retrobulbar anesthesia and a conventional ab externo incision, loss of lens material into the vitreous cavity occurred in all three postvitrectomy eyes.- - - - - - - - - - ranking = 2.5keywords = extraction (Clic here for more details about this article) |
8/14. Effect of cataract surgery and intraocular lenses on diabetic retinopathy.We reviewed a series of 137 cataract extractions with intraocular lenses (IOLs) in patients with diabetes, mellitus between 1977 and 1983. All patients were followed for an average of 36 months to determine if they subsequently showed progression of diabetic retinopathy. Divided into groups according to the type of procedure and IOL received, they were compared for age, sex, duration of diabetes, treatment required for the diabetes, intraoperative complications, and follow-up period. patients who had intracapsular cataract extractions with anterior chamber IOLs were three times as likely to show proliferative retinopathy as those who had extracapsular cataract extractions with posterior chamber IOLs. insulin-dependent patients were three to four times more likely to show progression to proliferation than noninsulin dependent patients. We conclude that, while some procedures are riskier for the diabetic eye, extracapsular lens extraction with implantation of a posterior chamber lens does not imply an increased risk of development of proliferative retinopathy.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
9/14. Progression of nonproliferative diabetic retinopathy following cataract extraction.Eight patients experienced progression of nonproliferative diabetic retinopathy following cataract extraction. Six patients underwent an uncomplicated extracapsular cataract extraction with placement of a posterior chamber intraocular lens, and in two patients, surgery was complicated by vitreous loss. In each case the retinopathy progressed to a severe exudative form of diabetic macular edema, characterized by diffuse retinal thickening and fluorescein leakage with increased dot and blot hemorrhages and lipid deposition. In all patients, clinically significant macular edema developed in the eye that had been operated on, and six patients received laser photocoagulation for this condition. Final visual acuity was worse than preoperative visual acuity in six of eight patients, and it was unchanged in two of six patients. No patient achieved a visual acuity better than 20/50. The fellow eyes, which were not operated on, remained stable during the follow-up period.- - - - - - - - - - ranking = 3keywords = extraction (Clic here for more details about this article) |
10/14. Nontraumatic ghost cell glaucoma--a case report.Ghost cell glaucoma (GCG) has recently been described following vitrectomy, cataract extraction, and penetrating or blunt trauma. We describe the occurrence of GCG in a phakic eye with no prior ocular trauma or surgery following vitreous hemorrhage from diabetic retinopathy. We postulate the occurrence of a spontaneous rupture of the anterior hyaloid face which allowed passage of ghost cells into the anterior chamber. A therapeutic vitrectomy was complicated by intraoperative vitreous hemorrhage. Two weeks postvitrectomy, GCG recurred and was successfully controlled by irrigation through an anterior chamber approach. This is the procedure of choice in GCG following vitrectomy and may eliminate the need for a second vitrectomy.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
