Using retro-mode imaging (RMI) and fundus autofluorescence (FAF) can be helpful in characterizing retinal dystrophies.
Using retro-mode imaging (RMI) and fundus autofluorescence (FAF) can be helpful in characterizing retinal dystrophies, according to a paper featured in the journal Bio Med. Central Ophthalmology.
A team led by Dr Battaglia Parodi Maurizio, Department of Ophthalmology, University Vita-Salute, Scientific Institute San Raffaele, Milan, Italy, included 18 consecutive patients with retinal dystrophies.
Each participant underwent ophthalmological assessments including best corrected visual acuity with ETDRS charts, blue-light fundus autofluorescence, (BL-FAF), near-infrared fundus autofluorescence (NIR-FAF) and RMI. The primary outcome was abnormal patterns on RMI and the secondary outcome was the correlation between BL-FAF findings and NIR-FAF findings.
The results revealed that the main feature of RMI is represented by a pseudo-3D pattern of all the posterior pole lesions. There were no fixed correlations between RMI, BL-AF and NIR-AF imaging. The non-invasive diagnostic tools could obtain additional information on clinical setting and patients monitoring.
