BACKGROUND To describe the first reported case of toxic optic neuropathy secondary to docetaxel (Taxotere®) chemotherapy. CASE PRESENTATION A 53-year-old female presented with predominantly unilateral visual loss, but extensive bilateral visual field defects and bilateral optic nerve head swelling 2 weeks after first dose of docetaxel (Taxotere®) and trastuzumab (Herceptin®) chemotherapy for ...
A retrospective analysis of clinical profiles of 20 patients with anterior and posterior ischemic optic neuropathy and diabetic papillopathy was used to evaluate optic neuropathy in diabetes. We found that vascular optic neuropathy in diabetic patients resulted from microangiopathy, macroangiopathy, and certain structural factors in the optic nerve head.
In order to determine whether a possible barrier exists to diffusion of tracer into the optic nerve during development and to provide a basis for later studies of retrograde axonal transport in embryonic nerves, we studied the diffusion of horseradish peroxidase (HRP) into the nerve after vitreal injections in chicks ranging in age from embryonic day 6 to 3 days after hatching. We found that HR...

Shlomo Dotan, MD Department of Ophthalmology, Hebrew University Hadassah Medical Center, Jerusalem, Israel ABSTRACT Purpose: To demonstrate that slow-growing intracranial suprasellar mass lesions can be associated with optic disc cupping, clinically indistinguishable from glaucomatous optic neuropathy. Cases: At a neuro-ophthalmology tertiary clinic, a retrospective chart review identified four...
Clinically the presence of nerve fibre bundle defects in glaucoma and non-glaucomatous lesions, and altitudinal or vertical hemianopias in pre-chiasmal lesions has been known for a long time. These suggest a sectoral lesion in the optic nerve or retina. In the majority of such cases, no retinal lesion is seen to account for these visual field defects. It has been presumed that the lesion lies i...
