Objective:
To illustrate the role of non-contact widefield retinal imaging (NC-WFI) of retinopathy of prematurity (ROP) using the Clarus 700 high resolution true colour reflectance imaging.
Methods:
All babies were examined by the vitreoretinal faculty in a tertiary eye care centre from a period of March 2021 to November 2021 using the indirect ophthalmoscope after pupillary dilatation. ROP grading was done according to the revised ICROP (2005) classification. NC-WFI was then performed using the Clarus 700 high resolution true colour reflectance imaging (Carl Zeiss Meditec, Dublin, CA) in the retina diagnostic set up of a tertiary eye care centre.
Results:
A total of 22 babies (44 eyes) underwent NC-WFI from March 2021 to November 2021. 13 unique cases of retinopathy of prematurity with images captured on Clarus 700 and the clinical summary is described.
Conclusion:
Clarus is a non-contact wide field imaging (NC-WFI) system that can capture high resolution and true colour images (images of the fundus appear similar colour to direct observation by ophthalmoscopy) helping in more accurate diagnosis and grading of the severity of ROP.
