PURPOSE: To demonstrate a possible correlation between corneal ectasia and vitamin C deficiency.
METHODS: Case series.
RESULTS: This case series covers 3 patients with atypical features of corneal ectasia. All 3 had a peculiar general history and visited our tertiary ophthalmology department complaining about decreased visual acuity. Corneal tomography by Scheimpflug imaging (Pentacam) indicated an irregular astigmatism congruent with a corneal ectasia. A blood test diagnosed vitamin C deficiency.
CONCLUSIONS: To the best of our knowledge, this is the first time a possible correlation between corneal ectasia and vitamin C deficiency is established. Although more research is of course of the essence, it proves useful to determine vitamin C plasma levels in patients presenting with atypical ectasia. To the extent that vitamin C deficiency is indeed diagnosed, it should be substituted orally.
