ABSTRACT
BACKGROUND Patients with keratoconus are at increased risk of developing cataract at a younger age compared to the normal population. Predisposing factors include atopy and topical steroid use. In this case series we report the novel observation of splinter-shaped cortical cataract in 16 eyes of 14 patients with keratoconus in the absence of other risk factors of cataract development from a single center in Riyadh, Saudi Arabia. CASE REPORT This is a retrospective review of 16 eyes of 14 patients diagnosed with keratoconus and found to have splinter cortical cataract. Twelve patients had unilateral and 2 patients had bilateral splinter cortical cataract in the inferotemporal quadrant of the crystalline lens. Thirteen eyes (81.25%) had clinically proven keratoconus and 3 eyes (18.75%) were keratoconus suspects. All patients affirmed frequent eye rubbing and 62.5% of eyes had a history of vernal keratoconjunctivitis. Best corrected visual acuity (BCVA) by the logarithm of the minimum angle of resolution (LogMAR) was reported between 0 to 0.2 in 69% of eyes (11 eyes) and 4 eyes (25%) had BCVA of 0.3 to 0.6, and 1 eye (6%) had BCVA of 1.3. CONCLUSIONS Splinter-shaped cortical cataract could be a sign of frequent eye rubbing. Careful examination of the crystalline lens with dilated pupil may reveal peripheral cortical opacities in the inferotemporal quadrant, which can alert the physician that the patient has habitual eye rubbing and is at increased risk of keratoconus development or progression.
