Abstract

PURPOSE
To investigate the advantages of ultrawide-field fluorescein angiography (FA) over the standard fundus examination in the evaluation of diabetic retinopathy (DR).
METHODS
Ultrawide-field FAs were obtained in 118 eyes of 59 diabetic patients; 11 eyes with no DR, 71 eyes with nonproliferative diabetic retinopathy (NPDR), and 36 eyes with proliferative diabetic retinopathy (PDR), diagnosed by the standard method. The presence of peripheral abnormal lesions beyond the standard seven fields was examined.
RESULTS
Ultrawide-field FA images demonstrated peripheral microaneurysms in six (54.5%) of 11 eyes with no DR and all eyes with moderate to severe NPDR and PDR. Peripheral retinal neovascularizations were detected in three (4.2%) of 71 eyes with NPDR and in 13 (36.1%) of 36 eyes with PDR. Peripheral vascular nonperfusion and vascular leakage were found in two-thirds of eyes with severe NPDR and PDR.
CONCLUSIONS
Ultrawide-field FA demonstrates peripheral lesions beyond standard fields, which can allow early detection and a close evaluation of DR.

  Fig. 1 (A,B) Ultrawide-field fluorescein angiography shows peripheral microaneurysms (arrows) outside the seven standard Early Treatment Diabetic Retinopathy Study (ETDRS) fields in eyes diagnosed as normal fundus with the standard fundus examination. (C,D) Peripheral retinal neovascularizations (arrows) were found outside the standard seven ETDRS fields in eyes diagnosed as nonproliferative diabetic retinopathy by the standard method. (E,F) Multiple lesions of neovascularization (arrows), vascular leakage (blank arrows), and nonperfusion (arrow heads) observed beyond the borders of standard fields in ultrawide-field fluorescein angiography.
