Prostaglandin analogs (PGAs) can cause reversible conjunctival hyperpigmentation in patients with ocular hypertension. Discontinuing PGAs led to significant improvement in this condition, highlighting its potential reversibility.
Area of Science:
- Ophthalmology
- Dermatology
Background:
- Ocular hypertension management often involves prostaglandin analogs (PGAs).
- Conjunctival hyperpigmentation is a potential side effect of certain medications.
Observation:
- A 54-year-old male with ocular hypertension developed bilateral limbal conjunctival hyperpigmentation after six years of PGA use.
- The hyperpigmentation progressively increased over time.
Findings:
- Discontinuation of travoprost (a PGA) and switching to brinzolamide resulted in significant improvement of conjunctival pigmentation within a year.
- This case represents the first documented instance of PGA-induced conjunctival pigmentation that reversed upon medication cessation.
Implications:
- Clinicians should consider PGA-induced conjunctival hyperpigmentation as a reversible condition.
- Awareness of this side effect is crucial when evaluating conjunctival melanocytic lesions in patients using PGAs.
- This finding may influence long-term treatment strategies for ocular hypertension.
