1/151. listeria monocytogenes endophthalmitis with a black hypopyon.A 68-year-old woman had a marked decrease in visual acuity, increased intraocular pressure, and acute iridocyclitis. She developed a pigmented hypopyon simulating an occult intraocular melanoma. Two anterior chamber paracenteses showed growth of listeria monocytogenes. The patient received systemic intravenous penicillin, topical fortified gentamicin sulfate drops, and intraocular injections of cephaloridine. On discharge from the hospital after a two-week stay, visual acuity had improved and intraocular pressure had decreased.- - - - - - - - - - ranking = 1keywords = pigment (Clic here for more details about this article) |
2/151. Posterior scleral choristoma in the organoid nevus syndrome (linear nevus sebaceus of Jadassohn).PURPOSE: To highlight the association of posterior osseous and/or cartilaginous ocular choristomas with epibulbar choristomas and the nevus sebaceus of Jadassohn. DESIGN: Small case series. PARTICIPANTS: Four patients with the organoid nevus syndrome. methods: Clinical and histopathologic studies in four patients with epibulbar lesions and nevus sebaceus of Jadassohn. MAIN OUTCOME MEASURES: Ophthalmoscopic findings of peripapillary lesions. Computed tomographic and ultrasonographic characteristic of posterior scleral lesions. Ocular histopathologic findings in one globe from one of the study subjects. RESULTS: Three patients had the triad of posterior osseous/cartilaginous ocular choristomas, anterior epibulbar choristomas, and nevus sebaceus of Jadassohn and one patient had anterior epibulbar choristomas and posterior osseous/cartilaginous ocular choristomas. ultrasonography and computed tomography were valuable in detecting scleral ossification or epibulbar cartilage or both. The ophthalmoscopic findings were similar to those of a choroidal osteoma. CONCLUSIONS: The presence of posterior osseous/cartilaginous ocular choristomas in a patient with epilepsy or epibulbar lesions or both suggests the diagnosis of nevus sebaceus of Jadassohn. Osseous/cartilaginous ocular choristomas should be suspected in patients with nevus sebaceus of Jadassohn and peripapillary hypopigmented fundus lesions.- - - - - - - - - - ranking = 1keywords = pigment (Clic here for more details about this article) |
3/151. adenoma of the pigmented ciliary epithelium: ultrastructural and immunohistochemical findings.We report the clinical and histological findings in a tumor of the pigmented ciliary epithelium. The tumor was detected because it had caused a unilateral cataract, and it was removed by local resection because a malignant melanoma could not be excluded. The diagnosis was established by light microscopy, and additional immunohistochemical and detailed ultrastructural studies were performed. The so-called foam cells which are considered typical of these adenomas appear to be mostly light microscopic artifacts and had no ultrastructural equivalent in the sections examined from our tumor. Our results also strongly support the hypothesis that no true glandular elements are formed and that, apart from the neoplastic tissue architecture, most of the pathological findings are related to melanosomes.- - - - - - - - - - ranking = 5keywords = pigment (Clic here for more details about this article) |
4/151. Compound nevus of the cornea simulating a foreign body.PURPOSE: To report a corneal nevus, without conjunctival involvement, that clinically simulated a metallic foreign body. methods: Case report with clinicopathologic correlation. RESULTS: A 22-year-old man developed a superficial pigmented lesion of his left cornea. It was suspected to be a chronically retained foreign body, but a melanocytic neoplasm could not be excluded. The lesion was removed by lamellar keratectomy and proved histopathologically to be a compound nevus of the cornea, without conjunctival involvement. CONCLUSIONS: Melanocytic nevus can rarely occur in the cornea. Involvement of the cornea by a melanocytic lesion does not necessarily imply a malignant melanoma.- - - - - - - - - - ranking = 1keywords = pigment (Clic here for more details about this article) |
5/151. Ocular-central nervous system lymphoma mimicking posterior scleritis with exudative retinal detachment.OBJECTIVE: We describe an unusual ocular presentation of ocular-central nervous system lymphoma in a young patient. DESIGN: Interventional case report and literature review. methods: A previously well 24-year-old white woman presented with left eye pain and reduced vision. Episcleral injection, globe tenderness, an afferent pupil defect, and exudative retinal detachment were present. Computed tomographic scan of the head and orbits demonstrated scleral thickening, retinal detachment, and no other abnormality. A provisional diagnosis of posterior scleritis with exudative retinal detachment was made. Investigation for underlying connective tissue diseases was negative. There was an initial prompt response to corticosteroid therapy. The patient's symptoms and signs then recurred, and a left third cranial nerve palsy developed. Systemic investigations including lumbar puncture ultimately led to the diagnosis of primary T-cell central nervous system (CNS) lymphoma. serologic tests for human immunodeficiency virus were negative. MAIN OUTCOME MEASURES AND RESULTS: The patient underwent orbital and cranial irradiation and intrathecal and systemic chemotherapy. Despite an initial response to treatment, she returned with a recurrence of the lymphoma in the anterior segment of the left eye. Her systemic disease progressed rapidly, and she died shortly thereafter. CONCLUSIONS: This patient's young age and initial presentation mimicking posterior scleritis with unilateral exudative retinal detachment, without evidence of vitreous involvement, are highly unusual for ocular involvement in primary CNS lymphoma. A review of the literature highlights the atypical nature of this presentation.- - - - - - - - - - ranking = 73.15628214817keywords = detachment, retinal detachment (Clic here for more details about this article) |
6/151. A case of glaucoma associated with sturge-weber syndrome and nevus of ota.The sturge-weber syndrome consists of a unilateral port-wine hemangioma of the skin along the trigeminal distribution and is accompanied by an ipsilateral leptomeningeal angioma. glaucoma is present in approximately half of the cases. The nevus of ota is a melanocytic pigmentary disorder, most commonly involving the area innervated by the trigeminal nerve. Elevated intraocular pressure, with or without glaucomatous damage, is observed in 10% of the cases. We report the first case of glaucoma associated with sturge-weber syndrome and nevus of ota in korea.- - - - - - - - - - ranking = 1keywords = pigment (Clic here for more details about this article) |
7/151. scleral buckling in retinoblastoma: case report.In the course of treating retinoblastoma in a monocular child, a progressive retinal detachment occurred. Although no retinal break was demonstrated, several clinical features suggested that the detachment was rhegmatogenous. A successful scleral buckling procedure was performed without adverse sequelae. The rationale for this approach is discussed.- - - - - - - - - - ranking = 15.406095249061keywords = detachment, retinal detachment (Clic here for more details about this article) |
8/151. anterior chamber infiltrates associated with systemic lymphoma: report of two cases and review of the literature.PURPOSE: To describe the clinicopathologic features of two patients with systemic lymphoma who developed anterior chamber (AC) infiltrates of lymphoma cells. DESIGN: Two case reports and literature review. methods: The clinical and pathologic findings in two patients with AC infiltrates secondary to systemic B-cell lymphoma are reviewed. MAIN OUTCOME MEASUREMENTS: Clinical observation and cytologic/flow cytometric examination of the infiltrate after AC aspiration. RESULTS: One patient presented with uveal infiltration, an exudative retinal detachment and an AC infiltrate. Systemic evaluation revealed a follicular lymphoma involving several groups of lymph nodes. The second patient with a known history of abdominal lymphoma was found to have blurred vision, photophobia and an AC infiltrate. Flow cytometric analysis of the AC infiltrate in both patients showed phenotypes consistent with the patients' systemic lymphomas. CONCLUSIONS: A pseudohypopyon in an adult may represent either the initial manifestation or a later complication of systemic lymphoma, similar to what has been reported in acute leukemia.- - - - - - - - - - ranking = 9.6250311498515keywords = detachment, retinal detachment (Clic here for more details about this article) |
9/151. A unique case of primary corneal melanoma.PURPOSE: To report a unique case of primary corneal melanoma. methods: A 59-year-old white woman underwent keratectomy to remove a pigmented rapidly enlarging growth on the corner of her left eye. The specimen was submitted for histopathologic examination. RESULTS: Ophthalmic examination disclosed no association with limbal or conjunctival melanocytic abnormalities. Histopathologic studies demonstrated nodular malignant melanoma. CONCLUSION: Possible development of primary corneal melanoma should be considered in diagnosing all cases with a past history of corneal melanin pigmentation.- - - - - - - - - - ranking = 2keywords = pigment (Clic here for more details about this article) |
10/151. Metastatic cutaneous melanoma to the vitreous cavity masquerading as intermediate uveitis.PURPOSE: To report a patient with metastatic cutaneous melanoma (MCM) presenting as intermediate uveitis. methods: We examined a 49-year-old man with malignant cutaneous melanoma and central nervous system (CNS) metastasis who was initially treated for bilateral intermediate uveitis. Biomicroscopic examination disclosed a normal anterior segment and vitreous organization with red blood cells (RBC) and some non-pigmented cells in both eyes. Funduscopy disclosed a retinal metastasis in the right eye, but vitreous organization precluded visualization of the retina in the left eye. RESULTS: The first diagnostic vitrectomy was negative for malignant cells in the left eye. However, progressive worsening of the condition persuaded us to repeat vitrectomy in the left eye and to do it in the right eye too. Vitreous samples were positive for malignant melanoma cells in both eyes. CONCLUSIONS: Metastatic cutaneous melanoma to the vitreous cavity is exceedingly rare and may masquerade as intermediate uveitis. It should be considered in the differential diagnosis of unusual uveitis and masquerade syndromes.- - - - - - - - - - ranking = 1keywords = pigment (Clic here for more details about this article) |
