Summary
Intranasal cocaine abuse can trigger acute angle-closure glaucoma in susceptible individuals. Prompt Nd:YAG laser peripheral iridotomy successfully treated this glaucoma case.
Area of Science:
- Ophthalmology
- Toxicology
Background:
- Acute angle-closure glaucoma (AACG) is an ophthalmic emergency.
- Intranasal drug abuse is a growing public health concern.
Observation:
- A 55-year-old male presented with acute angle-closure glaucoma in his right eye.
- The onset of glaucoma symptoms coincided with recent intranasal cocaine use.
Findings:
- Cocaine use was identified as the likely trigger for AACG.
- The patient's glaucoma resolved following Nd:YAG laser peripheral iridotomy.
Implications:
- Cocaine-induced mydriasis can precipitate angle closure in predisposed eyes.
- Awareness of this association is crucial for emergency room physicians and ophthalmologists.
- Screening for substance abuse may be warranted in patients with unexplained AACG.
