Summary
Systemic drugs can cause eye problems, but serious vision loss is rare. Clinicians must monitor patients for adverse ocular reactions and screen for risks, especially with long-term treatments.
Area of Science:
- Ophthalmology
- Pharmacology
- Clinical Medicine
Background:
- Systemic medications can lead to various ocular adverse effects.
- While most drug-induced eye issues are mild, some can cause irreversible vision impairment.
- Clinicians must be aware of these risks and inform patients.
Purpose of the Study:
- To review potential adverse ocular reactions associated with commonly prescribed systemic drugs.
- To emphasize the importance of patient screening and baseline measurements before initiating therapy.
- To highlight specific drug-induced ocular toxicities and their management.
Main Methods:
- Literature review of systemic drugs with known ocular side effects.
- Analysis of reported cases and clinical guidelines for drug-induced ocular toxicity.
- Categorization of adverse effects by drug class and potential severity.
Main Results:
- Chloroquine retinopathy, amiodarone-induced optic neuropathy, and corticosteroid-induced cataracts are significant risks.
- Ethambutol and high-dose tamoxifen can cause optic neuropathy and maculopathy, respectively.
- Anticholinergic drugs may affect accommodation and pupillary dilation, potentially triggering glaucoma.
Conclusions:
- Proactive patient monitoring and baseline visual assessments are crucial for managing drug-induced ocular toxicity.
- Understanding the cumulative effects of prolonged treatment is essential for preventing irreversible vision loss.
- Early detection and intervention can often reverse or mitigate drug-related ocular damage.
