    Summary
    This summary is machine-generated.

    Self-injecting methylphenidate (Ritalin) can lead to intraretinal talc emboli, causing vision loss. This study details the clinical syndrome and pathogenesis of these retinal emboli.

    Area of Science:

    • Ophthalmology
    • Toxicology
    • Pharmacology

    Background:

    • Methylphenidate (Ritalin) abuse via self-injection is a growing concern.
    • Intraretinal talc emboli are a known complication of intravenous drug abuse.

    Observation:

    • Twelve patients presenting with bilateral intraretinal talc emboli were studied.
    • All patients reported long-term, high-dose self-injection of methylphenidate.
    • Ophthalmoscopic examination revealed characteristic yellow-white particles in the macular area.

    Findings:

    • Two patients experienced reduced vision due to retinal vascular occlusion.
    • The study presents the clinical syndrome, ophthalmoscopic appearance, and fluorescein angiographic findings.
    • Pathogenesis of self-injected retinal emboli is discussed.
