Patients using thyroxine had also increased incidence of ARMD than non using of thyroxine. There were statistically higher significant percent of marriage, educational level and smoking in patients with thyroid disorders with ARMD than euthyroid (p=0.03. 0.06, 0.001 respectively). In thyroid disorders patients, there were a significant differences between patients had ARMD or had not as regard diabetes, hypertension and cholesterol level (p=0.04, 0.09, 0.03 respectively).
