HIV and Vision: Symptoms, Risks & the Importance of Testing

Visual symptoms are uncommon in early HIV and typically appear only with advanced immunosuppression (CD4 < 100 cells/μL).

HIV-Associated Ocular Conditions

• CMV retinitis: Floaters, flashes, blind spots, vision loss (AIDS-defining).
• Progressive outer retinal necrosis (PORN): Rapid, aggressive retinal necrosis (varicella-zoster).
• HIV retinopathy: Cotton-wool spots, microaneurysms, hemorrhages (non-infectious, microvascular).
• Herpes zoster ophthalmicus: Painful vesicular rash, keratitis, uveitis.
• Ocular syphilis, TB, toxoplasmosis: Opportunistic co-infections.

Symptoms Warranting Urgent Eye Exam

• Blurred or decreased vision
• New floaters/flashes
• Visual field defects (blind spots)
• Photophobia, eye pain, redness
• Color vision changes

Key Points

• Routine dilated eye exams are recommended for all HIV+ patients.
• ART (antiretroviral therapy) preserving CD4 count is the best prevention.
• Negative HIV test with visual symptoms → evaluate for other causes (diabetes, hypertension, autoimmune, etc.).
• Practice safe sex; get tested regularly. Early HIV diagnosis saves vision and lives.
