  • Characteristics of fundus autofluorescence in primary retinitis pigmentosa and its relationship with visual fields

    Objective To observe the characteristics of fundus autofluorescence (AF) in short wavelength AF (SW-AF) and Near Infrared AF (NIR-AF), and their relationship with visual fields. Methods Twelve patients (24 eyes) with primary RP were enrolled in this study. The patients included nine males (18 eyes) and three females (six eyes). The patients aged from 15 to 69 years, with a mean age of (35.33plusmn;15.03) years. All the patients were examined for color photography, SW-AF, NIR-AF, visual fields and optical coherence tomography examination. Results There were hyper-AF ring of varying sizes in posterior pole by SW-AF and NIR-AF examinations. The area of hypo-AF which located in SW-AF hyper-AF ring had a positive correlation with the area of hyper-AF in the NIR-AF (r=0.662,P<0.05). OCT showed that outside the hyper-AF ring, there were disconnected inner segment/outer segment (IS/OS) junction and external limiting membrane, and thinned outer nuclear layer and retinal pigment epithelium. Peripheral retinal osteocytes-like pigmentation showed non fluorescence in SW-AF and NIR-AF. The plaque-like area showed mottled and low fluorescence examined by SW-AF. SW-AF hyper-AF ring had a positive correlation with visual fields (r=0.492,P<0.05). Conclusions The area of hypo-AF inside of the SW-AF hyper-AF ring is related to visual fields in RP patients. The retinal structures in the hypo-AF area inside of the SW-AF hyper-AF ring, and in the NIR-AF hyper-AF region are normal.
