Advanced visual field loss secondary to optic nerve head drusen: case report and literature review.

Background: Optic nerve head drusen (ONHD) is a relatively uncommon condition that results from calcific degeneration of axons within the optic nerve. The abnormal drusen bodies can enlarge, compressing normal nerve structures, and ultimately may result in vision loss. Drusen often are discovered through clinical evaluation with a dilated funduscopic examination.

Ocular manifestations of AIDS: new considerations for patients using highly active anti-retroviral therapy (HAART).

Highly active anti-retroviral therapy (HAART) effectively restores the immune system and lowers the viral load in patients with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). Since widespread use of HAART drugs began in 1996, many AIDS patients are living longer and enjoying a higher quality of life. The incidence of AIDS-related ophthalmic infections, such as cytomegalovirus (CMV) retinitis, have declined sharply.
