PURPOSE: It is known that macula can be affected adversely in glaucoma. In this study, we aimed to evaluate the functional and morphologic changes of macula in patients having glaucoma using Microperimeter-1 (MP-1), Humphrey field analyzer (HFA), and Heidelberg Retina Tomograph II (HRT-II). MATERIALS AND METHODS: This prospective study consisted of 43 patients having primary open angle glaucoma. Control group consisted of 26 normal cases. Macular threshold was evaluated with HFA macula threshold test and MP-1 Humphrey macula pattern. Morphometric evaluation of macula was performed with HRT-II. The results were evaluated by independent samples t test and receiver operator curves. RESULTS: Macular sensitivity was lower in patients having glaucoma with both HFA and MP-1 in all quadrants (P=0.003 for HFA and P=0.002 for MP-1). The macular thickness measurements obtained with HRT-II was not significant between glaucoma patients and control group (P=0.153). The difference between HFA and MP-1, HFA and HRT-II, MP-1 and HRT-II was not statistically significant (P=0.302, 0.110, and 0.481, respectively). CONCLUSIONS: Perimetric macular changes can occur while macular topographic remains stable in patients with glaucoma. MP-1 correlates with HFA in detecting glaucomatous visual field defect in macular area.
