To evaluate the utility of widefield imaging in the diagnosis and management of retinal dystrophies in a paediatric population
Manchester Royal Eye Hospital, Oxford Road, Manchester, U.K., M13 9WL
19 non-consecutive patients aged 4 to 17 years with retinal dystrophies were imaged. Optos® images were obtained through a fully dilated pupil allowing for the assessment and documentation of up to 200 internal degrees of the retina at one time and in correct orientation with a simultaneous view of the posterior pole, equatorial retina and periphery, via the use of low-powered laser wavelengths (532nm and 633nm) which allow simultaneous pseudocolour, green-free and red-free imaging. A 532 nm wavelength laser allowed for widefield autofluorescence. Individual laser separation allowed for review of each chorio-retinal layer.
Retinal dystrophies (n=19), consisting of X-linked Retinitis Pigmentosa (2); Rod-cone (2); cone-rod (3); achromatopsia (1); X-linked retinoschisis (2); congenital stationary night blindness (2); Ushers syndrome (2); Gyrate atrophy (2); and mucopolysaccharidosis II (1); Doyne’s Honeycomb retinal dystrophy(1); unknown foveo-macular dystrophy (1) and unknown retinal dystrophy (1).
Optos® Widefield Retinal Imaging allowed easier and rapid identification of retinal dystrophies when compared to standard biomicroscopy and fundus photography, with objective and effective recording of central and peripheral chorio-retinal dystrophies in children. Compared to standard retinal imaging, Optos enabled greater consistency in image quality between central and peripheral retinal images in children with moderate levels of co-operation.
