1/14. True exfoliation of the lens capsule.True exfoliation or lamellar delamination of the lens capsule is a rare disorder in which the lens capsule is thickened and the superficial portion of the lens capsule splits from the deeper layer and extends into the anterior chamber. The pathogenesis of this disorder is not clear, but intense infrared radiation has been thought to be the main causative factor. We describe a patient with a history of heat exposure who had a cataract and was found to have bilateral delamination of the anterior lens capsule. Findings from light microscopy and scanning and transmission electron microscopy demonstrated a lamellar separation of the anterior portion of the lens capsule, confirming the diagnosis of true exfoliation.- - - - - - - - - - ranking = 1keywords = capsule (Clic here for more details about this article) |
2/14. Visually significant cystoid macular edema in pseudophakic and aphakic patients with glaucoma receiving latanoprost.PURPOSE: To investigate the incidence of visually significant cystoid macular edema associated with the use of latanoprost in patients with glaucoma after cataract surgery. patients AND methods: This is a multicenter, retrospective study of 185 patients, of whom 173 were pseudophakic (212 eyes) and 12 were aphakic (13 eyes), who were treated for glaucoma with latanoprost 0.005%. The posterior lens capsule was intact in 125 eyes, open or absent as a result of surgery in 25 eyes, and status-post-yttrium-aluminum-garnet capsulotomy in 75 eyes. visual acuity was documented before and after initiating latanoprost therapy, and patients with a reduction of two or more lines on the Snellen chart were examined by fluorescein angiography for cystoid macular edema. RESULTS: Visual reduction was documented in four (2.16%) patients. Three of the four patients had cystoid macular edema, and the fourth was thought to have lost a central island of vision from glaucoma. The three patients with cystoid macular edema all had ruptured posterior capsules, requiring anterior vitrectomy, and one had a previous episode of cystoid macular edema 3 years before starting latanoprost therapy. CONCLUSION: These findings suggest that visually significant cystoid macular edema associated with latanoprost therapy in pseudophakic or aphakic patients is uncommon. If there is a cause-and-effect relationship between latanoprost therapy and clinically significant cystoid macular edema, the incidence appears to be low.- - - - - - - - - - ranking = 0.22222222222222keywords = capsule (Clic here for more details about this article) |
3/14. True exfoliation of the lens capsule following uveitis.PURPOSE: To report a rare case of true exfoliation of the lens capsule following panuveitis, with slit-lamp photographs before and following the development of the true exfoliation. methods: Case report. review of the history and clinical features of a 70-year-old woman who developed true exfoliation during the treatment for panuveitis. RESULTS: After 7 months of treatment for bilateral panuveitis with topical steroid and tropicamide, the patient developed a thin, transparent membrane arising on the lens surface in the right eye. A diagnosis of true exfoliation of the lens capsule was made. CONCLUSIONS: True exfoliation of the lens capsule following uveitis may occur due to the weakening of the anterior capsule by metabolic disorder caused by uveitis and precipitated by repeated mydriasis.- - - - - - - - - - ranking = 0.88888888888889keywords = capsule (Clic here for more details about this article) |
4/14. Pigment dispersion with elevated intraocular pressure after AcrySof intraocular lens implantation in the ciliary sulcus.A 45-year-old white woman had phacoemulsification with intraocular lens (IOL) implantation. The surgery was routine except for a linear tear in the posterior capsule; there was no disruption of the anterior vitreous face. After residual soft lens matter was removed, an AcrySof IOL was placed in the ciliary sulcus. One month postoperatively, the patient presented with an intraocular pressure (IOP) of 30 mm Hg and signs of pigment dispersion with 360 degrees of heavy pigmentation of the trabecular meshwork and iris transillumination defects. intraocular pressure was controlled with a topical beta-blocker. The optic disc appearance and visual field remained normal, but the uniocular hyperpigmentation of the trabecular meshwork was still present. We hypothesize that the sharp square edge of the AcrySof IOL increases the risk of a chafing effect on the posterior iris pigment and advocate that this IOL be placed in the capsular bag and ideally have 360 degrees of protective overlapping of the anterior capsule over the edge of the optic.- - - - - - - - - - ranking = 0.22222222222222keywords = capsule (Clic here for more details about this article) |
5/14. Late onset lens particle glaucoma as a consequence of spontaneous dislocation of an intraocular lens in pseudoexfoliation syndrome.PURPOSE: To report acute onset lens particle glaucoma associated with pseudoexfoliation-related dislocation of an intraocular lens implant 12 years after cataract surgery. methods: Case report. RESULTS: An 80-year-old woman presented with acute onset of left eye pain that was associated with white fleck-like particles circulating in the anterior chamber and an intraocular pressure of 48 mm Hg. The posterior chamber intraocular lens within the capsular bag was positioned more posteriorly to the iris plane than usual, and pseudoexfoliative material was present on the lens capsule and the zonules. anterior chamber aspirate confirmed the presence of lens cortical fibers. CONCLUSION: Spontaneous dislocation of the posterior chamber intraocular lens in patients with pseudoexfoliation syndrome several years after cataract surgery may liberate lens cortical material, causing lens particle glaucoma.- - - - - - - - - - ranking = 0.11111111111111keywords = capsule (Clic here for more details about this article) |
6/14. Anterior capsular phimosis in eyes with a capsular tension ring.A 64-year-old woman with zonular weakness in the left eye and a 79-year-old man with bilateral pseudoexfoliation and intraoperative zonular dehiscence had phacoemulsification with in-the-bag implantation of a single-piece poly(methyl methacrylate) intraocular lens (IOL) and a capsular tension ring. Ten to 12 weeks postoperatively, all 3 eyes developed significant visual loss secondary to capsule shrinkage and occlusion of the capsulorhexis opening. All eyes had a neodymium:YAG laser radial anterior capsulotomy, anterior capsulectomy, or both. visual acuity was restored in all eyes despite slight IOL decentration.- - - - - - - - - - ranking = 0.22222222222222keywords = capsule (Clic here for more details about this article) |
7/14. Complete anterior capsule contraction after phacoemulsification with acrylic intraocular lens and endocapsular ring implantation.A 69-year-old man with pseudoexfoliation syndrome and bilateral cataract had phacoemulsification with continuous curvilinear capsulorhexis and implantation of a morcher endocapsular ring and AcrySof acrylic intraocular lens (IOL) (Alcon). Two months later, the patient had vision loss in the left eye with a visual acuity of 20/500. He presented with anterior capsule fibrosis in both eyes, with complete occlusion of the capsule opening in the left eye and mild occlusion in the right eye. After a neodymium:YAG laser anterior capsulotomy in the left eye, visual acuity was 20/20. This case shows that endocapsular ring implantation does not prevent anterior capsule contraction syndrome but can prevent IOL decentration.- - - - - - - - - - ranking = 0.77777777777778keywords = capsule (Clic here for more details about this article) |
8/14. Dense pigmentation of the posterior lens capsule associated with the pigment dispersion syndrome.PURPOSE: To report an unusual case of pigment dispersion syndrome associated with unilateral dense pigmentation of the posterior lens capsule. methods: Case report. RESULTS: A 59-year-old male with bilateral pigment dispersion syndrome presented with progressive decrease in visual acuity in the left eye over the past 10 to 20 years. Clinical examination revealed the typical findings of pigment dispersion syndrome including the presence of bilateral Krunkenberg spindles, iris transillumination defects, and heavy trabecular meshwork pigmentation. Of note, there was remarkably dense pigmentation of the posterior lens capsule in the eye with decreased visual acuity. CONCLUSION: Pigmentation of the posterior lens capsule may be a rare finding associated with pigment dispersion syndrome. Such a finding suggests that there may be aqueous flow into the retrolental space in some patients with this condition. The optimal treatment of this unusual condition remains undetermined.- - - - - - - - - - ranking = 0.77777777777778keywords = capsule (Clic here for more details about this article) |
9/14. Anterior "lenticonus" in exfoliation syndrome.Presence of exfoliation syndrome (XFS) is associated with an increased risk of complications during cataract surgery. This risk is, in part, dependent on the severity of XFS. We describe a central bulge ("lenticonus") in the anterior lens capsule of some eyes with XFS. This finding is associated with very fragile zonules and a high risk for intraoperative zonular dialysis.- - - - - - - - - - ranking = 0.11111111111111keywords = capsule (Clic here for more details about this article) |
10/14. Posteriorly dislocated capsular tension ring.A 69-year-old man who had pseudoexfoliation and significant nuclear cataract underwent cataract surgery in his right eye. At the beginning of the phacoemulsification, inferior zonulolysis was observed and a capsular tension ring was implanted. Anterior vitrectomy was also performed because of vitreous in the anterior chamber at the end of surgery. A tear in the posterior capsule could not be identified. Three days after surgery, the capsular tension ring was observed partially in the anterior vitreous. A 3-port pars plana vitrectomy was performed and the ring was removed. Three weeks later, the eye developed retinal detachment and was successfully repaired. Retinal complications can develop if the capsular tension ring moves into the vitreous.- - - - - - - - - - ranking = 0.11111111111111keywords = capsule (Clic here for more details about this article) |
