The mean MRD1 measurement before ptosis repair surgery was 1.65mm (±0.82), with significantly higher MRD1 after a long post-operatively period, of 3.2mm (±1.03) (Matched pairs,p<0.001). The mean total GBI score was 57.48 (±4.72) out of 90, after an average follow up period of 712...
visual stimulus deprivation was assumed to be the main cause of amblyopia in three eyes (21 %). In the rest 11 eyes (79 %), refractive error was assumed to be the main cause of amblyopia. 1 eye had severe hyperopia (>10 dioptre) and 1 eye had severe myopia (<−10 dioptre). ...
Figure 2: Measurement of the vertical palpebralaperture B. Margin–reflex distance1 (MRD1)The distance between the upper eyelid margin and the corneal reflex of a pen torchlight held by the examiner on which the patient fixates; the normal measurement is 4–5 mm (fig 3 a & b). The...
Margin reflex distance 1 (MRD1) is an accepted clinical measure of ptosis and is typically assessed using a hand-held ruler. In this work, we develop an AI model that enables automated measurement of MRD1 in self-recorded video clips collected using patient smartphones. Methods A 3...
