Summary
Stimulant abuse, particularly methamphetamine, can lead to ischemic stroke. This case highlights central retinal artery occlusion as a risk associated with intranasal drug use, warranting toxicology screening.
Area of Science:
- Ophthalmology
- Neurology
- Toxicology
Background:
- Stimulant drug abuse is a known risk factor for cerebrovascular events, including ischemic stroke.
- Central retinal artery occlusion (CRAO) is a rare but serious condition causing sudden vision loss.
- Intranasal drug administration bypasses first-pass metabolism, potentially increasing cardiovascular risks.
Purpose of the Study:
- To report a case of central retinal artery occlusion (CRAO) in a patient with a history of intranasal methamphetamine use.
- To emphasize the association between stimulant abuse and ischemic events affecting the eye.
- To highlight the importance of considering toxicology testing in patients with unexplained acute visual loss.
Main Methods:
- Case report of a 43-year-old female patient.
- Clinical presentation and ophthalmologic examination findings.
- Review of patient's substance use history and toxicology results.
Main Results:
- The patient presented with sudden, severe, and painless vision loss in one eye.
- Diagnosis of central retinal artery occlusion (CRAO) was confirmed.
- Toxicology testing revealed the presence of methamphetamine.
Conclusions:
- Intranasal methamphetamine use can precipitate central retinal artery occlusion (CRAO) in young to middle-aged adults.
- Acute visual loss in the context of suspected substance abuse should prompt urgent toxicology screening.
- This case underscores the potential for stimulant-induced vascular complications beyond the brain.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
