Abstract
Purpose: :
To evaluate the utility of widefield imaging in the diagnosis and management of retinal conditions in a paediatric population.
Methods: :
Thirty-one non-consecutive patients aged 13-months to 16 years 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 simultaneous view of the posterior pole, equatorial retina and periphery. Use of low-powered laser wavelengths (532nm and 633nm) that scan allowing simultaneous colour, green-free, red-free and green imaging. A 532 nm wavelength laser allowed for widefield autofluorescence. Individual laser separation allowed for review of each chorio-retinal layer.
Results: :
Patients were categorized according to disease: 12 retinal dystrophies, 6 vitreoretinopathies, 3 Coat’s disease, 2 retinoblastomas, 2 ocular trauma and 1 each of oculocutaneous albinism, myelinated nerve-fibres, epiretinal membrane, congenital hypertrophy of the retinal pigment epithelium, choroidal naevus and post-operative retinal detachment evaluation.
Conclusions: :
Optos® Widefield Retinal Imaging allowed easier and rapid identification of lesions when compared to standard biomicroscopy and fundus photography, with objective and effective recording of central and peripheral chorio-retinal lesions as well as vitreous abnormalities 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.
