1/6. Photocoagulation of iris nevus to control recurrent hyphema.

    PURPOSE: To report a case of recurrent hyphema caused by an iris nevus that was successfully treated with photocoagulation. METHOD: Case report. In a 30-year-old woman with recurrent hyphema secondary to an iris nevus, photocoagulation was applied to the iris nevus. RESULTS: Before photocoagulation of the iris nevus, the patient had increasing frequency of hyphema episodes. After treatment, no hyphema episodes occurred during 13 months of observation. CONCLUSION: Photocoagulation of the surface of an iris nevus may prevent recurrent hyphema.

2/6. iris varix simulating an iris melanoma.

    iris varix is rare and little is known about its clinical characteristics. We treated a thrombosed iris varix that simulated an iris melanoma. A 53-year-old man developed a dark brown iris mass and hyphema in his left eye. Ultrasound biomicroscopy revealed a circumscribed mass of the iris stroma. Because of suspicion for melanoma, it was removed by sector iridectomy. Histopathologic examination disclosed an extensive focus of stromal hemorrhage, partially surrounded by endothelial cells that showed immunoreactivity to vascular markers. The histopathologic diagnosis was thrombosed iris varix. iris varix is a rare condition that should be included in the differential diagnosis of iris melanoma.

3/6. Cavernous hemangioma of the iris in an infant.

    iris hemangioma is a rare intraocular tumor which can present with spontaneous hyphema. Juvenile xanthogranuloma, malignant melanoma with proliferation of vessels or hemorrhages in the region of cystic degeneration, and inflammatory granulomas are frequently confused with the true hemangiomas. Some authors have even questioned the very existence of iris hemangioma. Clinical case reports of iris hemangiomas with histopathologic evidence and clinical course after surgery are uncommon. We could not find any reports of iris vascular tumors confirmed using immunohistochemical staining with vascular markers. We report a case of a cavernous hemangioma of the iris in a 3-month-old infant treated surgically, and the histopathological findings and immunohistochemical analysis with vascular markers (factor viii and CD34) are also shown.

4/6. Management of prominent iris vascular tufts causing recurrent spontaneous hyphema.

    PURPOSE: To report the management of recurrent, spontaneous hyphema associated with florid iris vascular tufts in a patient presenting for cataract surgery. methods: Interventional case report and review of the literature; presentation of clinical findings, iris angiography, and the argon laser regimen used to minimize potential corneal complications with increased total treatment energy. RESULTS: An 80-year-old man with a 20-year history of bilateral, recurrent, spontaneous hyphema associated with extensive iris vascular tufts presented with visually significant cataracts. Serial argon laser photocoagulation treatment of the prominent, circumferential iris vascular tufts of the left eye arrested further episodes of spontaneous hyphema and facilitated uneventful cataract surgery. argon laser parameters were titrated to therapeutic effect during the initial treatment sessions, and sectoral photocoagulation of the circumferential vascular tufts was performed during a 5-month period to accommodate increased laser power and energy. The total energy required to complete treatment of the extensive lesions was substantially more than that in similar previous reports; however, no adverse corneal complications were associated with the laser therapy. CONCLUSIONS: This case appears to represent the first description of chronic, bilateral, recurrent spontaneous hyphema associated with iris vascular tufts. argon laser treatment of symptomatic iris vascular tufts promotes resolution of recurrent, spontaneous hyphema and may serve to mitigate the risk of hemorrhage from these lesions during subsequent intraocular surgery. Conservative management of increased total treatment energy may minimize the potential risk of corneal decompensation with argon laser therapy.

5/6. iris cavernous hemangioma in a patient with recurrent hyphema.

    A 41-year-old woman presented with a hyphema in her right eye. Clinical examination revealed a vascular lesion of the iris that had enlarged over a 6-month period. The patient had no other evidence of ocular or cutaneous vascular malformations. Subsequently she experienced recurrent episodes of spontaneous hyphema, and there was objective evidence of growth of the lesion. Consequently, the lesion was excised by means of a sector iridectomy. Histopathological examination showed several large vascular compartments separated by thin, fibrous septa and lined by endothelium, consistent with a cavernous hemangioma. A benign iris melanocytic lesion was identified adjacent to the cavernous hemangioma. The intraocular pressure in the affected eye remained normal after the lesion was removed. After 6 months of follow-up no new hyphemas had developed. iris cavernous hemangioma should be added to the differential diagnosis of recurrent hyphema.

6/6. Histopathology of the eye in diffuse neonatal hemangiomatosis.

    PURPOSE: To report the ocular presentation and histopathology of a patient with diffuse neonatal hemangiomatosis. methods: Case report. A 3.7-kg female was born at term. Multiple hemangiomas were present, and the patient died 39 days after birth. RESULTS: Widespread cutaneous and visceral hemangiomas were present. Ophthalmic examination disclosed bilateral eyelid and conjunctival hemangiomas. The right eye had multiple iris hemangiomas, hyphema, vitreous hemorrhage, and discrete subretinal lesions. Histopathology of the right eye demonstrated hemangiomas involving the iris, ciliary body, and ciliary processes. CONCLUSION: Diffuse neonatal hemangiomatosis was associated with ophthalmic findings of multiple hemangiomas involving eyelid, conjunctiva, iris, ciliary body, and ciliary processes.
