1/39. Endocapsular hematoma: report of a case following glaucoma surgery in a pseudophakic eye.The authors describe a case of an endocapsular hematoma that occurred in a 69-year-old pseudophakic diabetic male following mitomycin C (MMC) augmented trabeculectomy for neovascular glaucoma (NVG). The clinical course of the patient is described, and the unique features of this case are presented and discussed. The endocapsular hematoma absorbed in 6 weeks with conservative management. The patient regained the preoperative visual acuity of 20/30, and his intraocular pressure was controlled without any glaucoma medication. The iris neovascularization regressed. This case is the first report of an endocapsular hematoma following glaucoma filtering surgery in a pseudophakic eye with neovascular glaucoma.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
2/39. 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 = 10keywords = iris (Clic here for more details about this article) |
3/39. Intracorneal inclusion of high-molecular-weight sodium hyaluronate following detachment of Descemet's membrane during viscocanalostomy.PURPOSE: Viscocanalostomy in accordance with Stegmann's technique is a new surgical option in the treatment of glaucoma. There are few reports available describing the specific complications of viscocanalostomy. We report a case of intracorneal inclusion of high-molecular-weight sodium hyaluronate following viscocanalostomy. CASE REPORT: A 66-year-old man with uncontrolled primary open angle glaucoma of his right eye and a history of argon laser trabeculoplasty underwent viscocanalostomy in accordance with Stegmann's technique. During the filling of Schlemm's canal, a limited lysis of Descemet's membrane advanced centrally in the clear cornea adjacent to the site of canalostomy forming an intracorneal bubble of high-molecular-weight sodium hyaluronate. Postsurgical slit-lamp biomicroscopy showed an intracorneal clear bubble within the corneal periphery without evidence of adjacent corneal edema and with no contact between the corneal endothelium and the iris. Follow-up examinations determined that the appearance of the corneal inclusion, essentially, was unchanged, with only a slight tendency of resorption. No signs of corneal scarring or endothelial decompensation could be noted. CONCLUSION: To date, we could not determine a significant corneal damage in conjunction with the described complication. However, it is difficult to predict the long-term clinical course of our patient. Corneal decompensation as a result of possible endothelial toxicity of high-molecular weight sodium hyaluronate as well as spontaneous absorption seem possible.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
4/39. Asymmetric pigment dispersion in a patient with the unilateral Adie pupil.PURPOSE: Pigmentary glaucoma is a bilateral disorder. When it occurs asymmetrically or unilaterally, a cause should be sought because it may help us to understand the pathophysiology of this condition better. We describe a patient with unilateral pigmentary glaucoma and the Adie pupil in the same eye and discuss the possible role of the Adie pupil in the development of the pigmentary glaucoma. methods: A case report. A 37-year-old woman presented with asymmetric pigment dispersion resulting in pigmentary glaucoma in the right eye and an unilateral Adie pupil in the same eye. RESULTS: We believe that the dilated Adie pupil in the right eye might have resulted in a decreased amount of relative pupillary block. This, then, might have led to an increased contact between the posterior iris and the zonules, resulting in greater pigment dispersion and trabecular obstruction in the right eye. CONCLUSION: It has been proposed that the pigment is liberated from the iris pigment epithelium because of the mechanical rubbing of the posterior iris against the anterior zonular packets. Our case supports this proposed mechanism of pigment release.- - - - - - - - - - ranking = 3keywords = iris (Clic here for more details about this article) |
5/39. Latanoprost-induced iris heterochromia and open-angle glaucoma: a clinicopathologic report.PURPOSE: To report the histopathologic and immunohistochemical findings from the iridectomy specimen of a patient with acquired unilateral iris heterochromia due to latanoprost. PATIENT AND methods: A 45-year-old woman with open-angle glaucoma and unilateral iris heterochromia was evaluated for uncontrolled intraocular pressure increase. Subsequently, the patient underwent trabeculectomy with mitomycin C and an iridectomy specimen was obtained for analysis. RESULTS: The histopathologic analysis of the iridectomy specimen did not reveal any nuclear atypia, nuclear crowding, or mitotic figures. Immunohistochemical studies showed that the iris melanocytes were negative for HMB45 and S-100, and weakly positive for Melan A. CONCLUSION: Latanoprost-associated iris color change may exhibit a diffuse, uniform, dark velvet-brown appearance, thereby simulating diffuse iris melanoma. Histopathologic and immunohistochemical analysis confirmed the benign characteristics of the affected iris melanocytes.- - - - - - - - - - ranking = 10keywords = iris (Clic here for more details about this article) |
6/39. iris synechia after laser goniopuncture in a patient having deep sclerectomy with a collagen implant.neodymium:YAG (Nd:YAG) goniopuncture is an efficient and safe treatment for low filtration through the trabeculo-Descemet's membrane after deep sclerectomy with a collagen implant (DSCI). The only reported complication of this procedure is choroidal detachment. However, we found an iris synechia in a patient whose intraocular pressure (IOP) was elevated again 1 month after Nd:YAG goniopuncture. Synechiolysis and peripheral iridectomy with Nd:YAG and argon lasers effectively removed the iris synechia, and IOP immediately dropped to the normal range. We believe that iris synechia is a potential complication that may cause elevated IOP after laser goniopuncture in patients having DSCI.- - - - - - - - - - ranking = 3keywords = iris (Clic here for more details about this article) |
7/39. Acute haptic-induced pigmentary glaucoma with an AcrySof intraocular lens.A 49-year-old man had uneventful endocapsular phacoemulsification with in-the-bag implantation of an AcrySof SA60AT single-piece intraocular lens (IOL) (Alcon) in the right eye. Twenty-seven days postoperatively, he presented with ocular pain, intraocular pressure of 48 mm Hg, 360 degrees of hyperpigmentation of the trabecular meshwork, and iris pigment epithelial atrophy in the region of the upper temporal haptic, which had dislocated into the sulcus. The patient made an excellent recovery following IOL removal and exchange. Scanning electron microscopy of the explanted IOL demonstrated that the haptic had a rough lateral surface and anterolateral edge. We do not think this IOL should be implanted in the sulcus placement of the heptics. In this article, we report the case of a patient with an AcrySof SA60ATIOL (Alcon) who developed acute pigmentary glaucoma when the inferior haptic slipped out of the bag and came into contact with the pigmented iris and ciliary body.- - - - - - - - - - ranking = 2keywords = iris (Clic here for more details about this article) |
8/39. iris cyst secondary to latanoprost mimicking iris melanoma.PURPOSE: To report an ocular side effect of topical latanoprost therapy. DESIGN: Single interventional case report. methods: A 73-year-old woman on latanoprost for primary open-angle glaucoma developed an iris cyst simulating an iris melanoma. RESULTS: The lesion disappeared over 8 weeks when latanoprost was stopped. CONCLUSIONS: In managing patients with iris-pigmented lesions, the list of medications should be reviewed. If the patient takes latanoprost, a trial off latanoprost is warranted.- - - - - - - - - - ranking = 7keywords = iris (Clic here for more details about this article) |
9/39. iris prolapse at the surgical site: a late complication of nonpenetrating deep sclerectomy.To investigate the occurrence and management of late-onset iris prolapse through the surgical wound after nonpenetrating deep sclerectomy. Two cases of iris prolapse that presented 8 and 10 months, respectively, after surgery for glaucoma were reviewed. One of the cases was associated with mild trauma. The postoperative follow-up was 5 and 24 months, respectively. The iris tissue bulge did not progress and there were no other complications. The visual acuity was not affected and the intraocular pressure was controlled with medical therapy. These cases demonstrate that the eye is weaker than normal at the surgical site after nonpenetrating deep sclerectomy, allowing iris protrusion. iris prolapse should be added to the list of late postoperative complications of nonpenetrating deep sclerectomy.- - - - - - - - - - ranking = 4keywords = iris (Clic here for more details about this article) |
10/39. Interstitial keratitis and iridoschisis in congenital syphilis.Bilateral interstitial keratitis and iridoschisis are reported in four cases with extraocular stigmata of congenital syphilis and positive syphilis serology. The iridoschisis was extensive in two cases giving the iris an unusual ragged appearance, while it was slight in one case. Iridoschisis may suggest the diagnosis of congenital syphilis, especially when interstitial keratitis is mild. Chronic open-angle glaucoma should be excluded in all patients with interstitial keratitis and iridoschisis.- - - - - - - - - - ranking = 1keywords = iris (Clic here for more details about this article) |
