To investigate the association between fundus autofluorescence (FAF) and retinal structure and function in retinitis pigmentosa (RP). For image acquisition, HRA2 (Heidelberg Engineering) and 3D-OCT1000 (Topcon Corp.) were used. Based on FAF examination, 88 eyes of 44 RP patients were categorized into three types. The area within the hyperautofluorescent ring and the area of preserved retinal autofluorescence with FAF was calculated. The association between the pattern of FAF and the residual area of the junction between the inner and outer segments of the photoreceptors (IS/OS line), and the relationship between the area within hyperautofluorescent ring, the area of preserved retinal autofluorescence and the mean deviation (MD) of static perimetry were assessed. Twenty-four eyes were with preserved retinal autofluorescence without hyperautofluorescent ring, 54 eyes were with hyperautofluorescent ring and ten eyes were with abnormal foveal autofluorescence both in the fovea and the periphery of the 30A degrees scan. In the first type, the IS/OS line was clearly detected. In the second type, the residual area of the partially distinct IS/OS line corresponded with the area within hyperautofluorescent ring with significant correlation between the area within hyperautofluorescent ring and the MD (R-2 = 0.705, p < 0.001); however, there was no correlation between the area of preserved retinal autofluorescence and the MD, or between the area of preserved retinal autofluorescence and the area within hyperautofluorescent ring. In the third type, the IS/OS line was completely absent. The residual IS/OS line can be found in the area inside the hyperautofluorescent ring and correlates with residual visual function.
