a 22 year-old woman presented with gradual visual loss in her right eye since 1990. medical and family histories were unremarkable. her visual acuity was 20/80 and 20/20 in right and left eyes respectively. slit lamp examination was quite normal with no relative afferent papillary defect.fundi of both eyes revealed subretinal lesion with optic nerve head involvement and subretinal fluid in papi...
Cavernous hemangioma of the optic chiasm is extremely rare, representing 1% or less of all cavernous hemangioma.1 Klein et al described the earliest reported lesion in 1979.2 Patients typically present with chiasmal apoplexy, characterized by sudden visual disturbance, headache, retro-orbital pain, and nausea.3 Acute dysfunction of the chiasm and/or optic nerve has been called chiasmatic apople...
A case of an hemorrhagic cavernous hemangioma of the optic chiasma and the adjacent optic nerve in a 23-year-old woman is reported. The visual disturbance has subacute onset following a sudden lateralized headache. Through a fronto-pterional approach, an intrachiasmal hematoma was evacuated. A small cavernous hemangioma was found in the hematoma cavity, and it was totally removed. Visual sympto...
A 69-year-old woman presented with generalized myasthenia gravis and a left orbital cavernous hemangioma (OCH), which elevated the optic nerve and displaced the external eye muscles. Cyclosporine treatment induced a gradual size reduction in the OCH, and consequently contributed to improved external ocular symptoms in combination with immunosuppressant effects.
Polypoidal choroidal vasculopathy has also been described in different pathological conditions including central serous chorioretinopathy(5), circumscribed choroidal hemangioma(6); melanocytoma of the optic nerve(7); pathological myopia and staphyloma(8); or choroidal osteoma(9). PCV seems to behave more like a neovasculopathy occurring in a variety of different diagnoses than a distinct abnorm...
We describe a case of a venous hemangioma that arose in the optic nerve sheath of the orbital apex in a 28-year-old man who presented with progressive vision loss. To the best of our knowledge, this is the first reported case of a venous hemangioma occurring at this location. A definitive diagnosis and partial excision was achieved via an endoscopic transsphenoethmoid approach with interactive,...
purpose: to report a case of unilateral severe visual loss and bilateral optic disc cupping secondary to brain metastasis of bronchogenic carcinoma patient and findings: a 48 year-old woman presented with severe visual loss of left eye without redness or pain or any systemic findings .clinical findings included decreased visual acuity of left eye to 4 m cf and (+3) positive marcus-gunn reflex ....
Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases. Furtherm...
Abstract Vascular anomalies grouped into vascular tumors (hemangioma) (HI) and malformation (VM) are benign lesions that difficult to distinguish from one another clinically often confused with each other at histopathology. This confusing terminology leads improper diagnosis, illogical treatment, misdirected research. study aimed GLUT 1, S-100, nerve bundle differentiate hemangioma malformation...
