Sensitivity, specificity and unweighted kappa were used to determine accuracy of AG. Logistic regression was used to explore risk factors associated with AM. The sensitivity and specificity of AG were 40% and 100%, respectively. The agreement of AG and HVF 10-2 was poor with kappa of 0.4. Creatinine clearance < 60 ml/min/1.73 m2 and bilateral macular abnormality were associated with AM at the same odds ratio of 8.9 (95% confidence interval: 1.3 to 61.2). AG may be used as an additional test between ocular evaluation visits providing the availability and low cost. Patients with renal impairment and bilateral macular abnormality are associated with AM.Mahidol UniversityMedicineArticleSCOPUS
