The anterior choroidal artery has several kinds of variations. Among them, the transposition of anterior choroidal artery and posterior communicating artery origins has been extremely rare. We report a case with cerebral aneurysm arising from posterior communicating artery which origin was distal to the anterior choroidal artery and review the relevant literature.

Choroidal melanoma primarily metastasizes to the liver. Isolated extrahepatic metastases have rarely been reported and they generally resulted in death within 6 months. We describe a patient who developed an isolated brain metastasis 27 years after his left eye was enucleated for choroidal melanoma. The metastasis was successfully treated with surgery and radiotherapy. The patient is alive and ...

Choroidal hemangioma is a rare congenital ocular tumor that can present as either circumscribed or diffuse. Circumscribed choroidal hemangioma (CCH) typically manifests as a red-orange mass within the posterior pole and appears similar to other ocular conditions, such as choroidal melanoma and choroidal metastasis. Proper diagnosis is crucial and is aided by the use of ancillary testing. CCH it...

Choroidal osteoma has been reported to be unilateral in approximately 80% of cases diagnosed with this condition. Herein we report the clinical characteristics and multimodal imaging findings in a rare case of bilateral multifocal choroidal osteoma. A 32-year-old female presented with decreased visual acuity (VA) in the right eye (20/100), though she had normal VA (20/20) in the left eye. Ophth...

Photodynamic therapy (PDT) has been used for treatment of various intraocular tumors including choroidal hemangioma, vasoproliferative tumor, amelanotic choroidal melanoma and choroidal neovascular membrane due to choroidal osteoma. This case report documents the effect of PDT for a presumed acquired retinal astrocytoma. A 42-year-old female with a juxtapapillary acquired astrocytoma was treate...

During a prospective study of age-related macular degeneration, evidence of diffuse Bruch's membrane disease was sought using fluorescein angiographic evidence of a prolonged choroidal filling phase. Dark-adapted static perimetry was done on eight eyes with this angiographic sign and on six eyes with a similar number of drusen but no manifest choroidal perfusion abnormality. Scotopic threshold ...

Posterior scleritis is a rare underdiagnosed condition that can potentially cause blindness. Its varied presentations lead to delayed or incorrect treatment. We present here the cases of two patients with nodular posterior scleritis mimicking a choroidal metastasis. Two female patients presented with a sudden unilateral visual loss associated with ocular pain. Fundus examination revealed tempor...

PURPOSE To describe a patient with Osler-Rendu-Weber syndrome who developed a nonsimultaneous intraoperative choroidal hemorrhage in each eye. METHOD Interventional case report. A 65-year-old Caucasian woman with Osler-Rendu-Weber syndrome developed a choroidal hemorrhage in the left eye during vitrectomy for a complicated retinal detachment with a poor visual outcome. Fifteen years later, sh...

To evaluate correlations between choroidal abnormalities, Lisch nodules, and age in patients with neurofibromatosis type 1 (NF1), we examined ten cases with NF1 using near-infrared reflectance imaging. Patients ranged in age from 4 to 39 years. The angle used for near-infrared reflectance imaging was 55°. We counted the total number of choroidal abnormalities in an area within a 55° angle cente...
