The results for the left eye were a best corrected visual acuity (BCVA) of 0.4 (-14.0/-0.5/90 ), an unremarkable ultrasound with an axial length of 22.99 mm and an anterior chamber depth of 2.99 mm (Fig. 1a), unremarkable biometry (Fig. 1b) findings, anterior lenticonus visible with a Pentacam camera system (Oculus Inc., Menlo Park, CA, USA) (Fig. 1c), oil droplet sign, and anterior lenticonus seen in a slit lamp examination (Fig. 2a, Fig. 2b), and distorted and blurred fundus images with discernable but unclear dots and flecks (Fig. 3a-c).
Left eye slit lamp examination revealing (a) oil droplet sign, and (b) anterior lenticonus.
