Answer

As many as 33% of HIV-infected patients on high-dose rifabutin experience intraocular inflammation, especially when an antifungal azole is used concurrently. Cidofovir causes uveitis in about 25-30% of patients and may lower intraocular pressure in as many as 10% of patients. Although mild uveitis may be treatable with topical corticosteroids, severe uveitis and hypotony can cause permanent visual loss. [19]

High-dose didanosine has been associated with retinal pigment epithelial abnormalities. Intravenous ganciclovir and acyclovir have been associated with corneal epithelial inclusions, whereas atovaquone is associated with corneal subepithelial deposits. With the exception of pigment epithelial changes, these adverse effects can resolve following discontinuation of the drug.
