Effects of Antiplatelet and Antioxidant Agents on Drusen Progression: A Pilot, Prospective Cohort Study
Navamindradhiraj University
174 participants
Dec 1, 2023
INTERVENTIONAL
Summary
The aim of this clinical trial is to evaluate the effect of low doses of antiplatelet medications (aspirin 81 mg/day or clopidogrel 75 mg/day) with or without a combination of antioxidants (N-acetylcysteine 600 mg/day) in a dry AMD patient with large drusen. Participants will divided in to three groups. * Participants who were already taking low dose antiplatelet medications. * Participants who take the antiplatelet drug mentioned above in addition to the antioxidant prescribed by the investigator * Participants does not use any medications.

- Patients can evaluate SD-OCT (Spectral domain optical coherence tomography), OCT angiography, and best-corrected visual acuity.
- Age range: 50-85 years
- Patients who have previously used antiplatelet drugs.
Exclusion Criteria4
