OBJECTIVE: This prospective study aims to evaluate how the vascular involvement of the optic disc, emphasised by angiofluorography (AFG), correlates with morphologic lesions observed by Heidelberg retinal tomography (HRT) II.
METHOD: AFG (Visucam Zeiss) and HRT II (with Moorfields regression and keratometry) have been performed on the study group -50 pts. with POAG- and in the control group -25 healthy subjects. Correlations have been calculated with Student (t) and Fisher tests. The value of p<0,05 was considered statistically significant.
RESULTS AND CONCLUSIONS: The number and size of hypo-fluorescent areas are significantly bigger in POAG pts. than in healthy subjects. They correlate with the involvement of retinal nerve fibers and C/D value. In POAG pts., areas of hypo-fluorescence are located mainly on the excavation's walls and the neuroretinal ring. Localization on the excavation's floor is not pathological, since it was also observed in the control group. The vascular involvement shown by angiofluorography significantly correlates with morphologic lesions observed by HRT II.
