Case report
We report a rare case of a 17-year-old patient who presented to our ophthalmology department with a sudden onset decreased visual acuity in the right eye. His best corrected visual acuity (BCVA) was 0.5/10 in the right eye and 10/10 in the left eye. No relevant medical history was noted except for cannabis consumption the day before his presentation. There was no history of trauma as well.
Slit-lamp examination of the anterior segment was unremarkable. Fundus examination revealed a peripapillary
Discussion
Retinal arterial macroaneurysms are localized dilatations of retinal arteries, measuring 100 to 250 μm in diameter, typically located in the posterior segment within the first three orders of bifurcations of the central retinal arterioles [1]. They are rare, with an estimated prevalence of 1 in 4500 individuals [2] and are most frequently observed in women over 60 years old with systemic hypertension [3]. RAMs are classified into three types: quiescent (asymptomatic), hemorrhagic (associated with
Conclusion
Our findings align with emerging evidence of cannabis-associated vascular dysregulation and suggest that cannabis use should be considered as a potential risk factor in young patients presenting with retinal hemorrhages of unclear etiology. Further research is needed to clarify cannabis implications on retinal vascular integrity.
