Summary
Long-term high-dose beta-carotene and canthaxanthin treatment for polymorphous light eruption can lead to yellow crystalline deposits in the macula. This may cause mild visual acuity and dark adaptation impairment.
Area of Science:
- Ophthalmology
- Dermatology
- Toxicology
Background:
- Polymorphous light eruption (PMLE) is a common photodermatosis.
- Beta-carotene and canthaxanthin are carotenoids used for PMLE treatment.
- Long-term high-dose supplementation requires monitoring for potential side effects.
Observation:
- A 55-year-old Turkish patient with PMLE was treated with high-dose beta-carotene and canthaxanthin for over 6 years.
- Fundus examination revealed dense, bright yellow crystalline deposits around the maculae.
- The patient reported a slight decrease in visual acuity and dark adaptation.
Findings:
- Long-term high-dose beta-carotene and canthaxanthin supplementation can result in ocular deposition.
- These deposits, appearing as glistening yellow crystals in the macula, are associated with mild visual disturbances.
- The findings suggest a potential link between carotenoid accumulation and retinal function.
Implications:
- This case highlights the importance of monitoring ocular health in patients on long-term high-dose carotenoid therapy.
- Ophthalmologists should be aware of potential carotenoid deposition and its visual consequences.
- Further research is needed to understand the mechanism and clinical significance of these ocular findings.
