Diffuse glaucomatous structural and functional damage in the hemifield without significant pattern loss.

30 Oct 2009 OBJECTIVES: To compare the retinal nerve fiber layer (RNFL) thickness and retinal sensitivity in the normal visual hemifield of glaucomatous eyes with localized visual field loss with those of normal eyes and eyes with suspected glaucoma, and to ... Read more...

Prediction of functional loss in glaucoma from progressive optic disc damage.

29 Sep 2009 OBJECTIVE: To evaluate the ability of progressive optic disc damage detected by assessment of longitudinal stereophotographs to predict future development of functional loss in those with suspected glaucoma. METHODS: The study included 639 eyes of ... Read more...

Racial variability of glaucoma risk factors between African Caribbeans and Caucasians in a Canadian urban screening population.

29 Sep 2009 BACKGROUND: The significance of race in the development and progression of glaucoma remains controversial, although in most cases the evidence shows greater prevalence and progression of the disease in African American populations. The purpose of ... Read more...

Technical information about 'Optic Disk'

Definition: The portion of the optic nerve seen in the fundus with the ophthalmoscope. It is formed by the meeting of all the retinal ganglion cell axons as they enter the optic nerve.
