Optic-pathway glioma: natural history demonstrated by a new empirical score.

30 May 2009 The optic pathway glioma uniquely involves the optic pathway in a relatively constant pattern, allowing for recurrent measurements of its extent and comparison within patients with the same diagnosis. Its natural history, however, is unpredictable. ... Read more...

Detrimental effects of cigarette smoke constituents on physiological development of extraocular and intraocular structures.

16 May 2009 No investigation has yet been accomplished to screen the detrimental effects of cigarette smoke condensate (CSC) and total particular matter solution (TPMS) on embryonic development of extraocular and intraocular structures. In this report, chicken ... Read more...

Neurobrucellosis: a partially treatable cause of vision loss.

29 Apr 2009 Involvement of the central nervous system due to brucellosis is rare and has a broad range of clinical manifestations. Reported here is a case of neurobrucellosis in a 13-year-old boy leading to visual impairment and unilateral hearing loss. Cranial ... Read more...

Technical information about 'Optic Chiasm'

Definition: The X-shaped structure formed by the meeting of the two optic nerves. At the optic chiasm the fibers from the medial part of each retina cross to project to the other side of the brain while the lateral retinal fibers continue on the same side. As a result each half of the brain receives information about the contralateral visual field from both eyes.
