Abstract
Purpose: :
To our knowledge, this study will be the first to identify the association between BMI and visual acuity among a keratoconus population.
Methods: :
A retrospective chart review of patients with the known diagnosis of keratoconus was performed and the past medical histories were examined for height, weight and visual acuity. Visual acuity was converted into LogMAR and body mass indices were calculated. The correlation coefficient was determined between patients with no history penetrating keratoplasty (PKP) and patients with a positive history for PKP.
Results: :
The correlation coefficient comparing obesity to visual acuity in patient with no history of PKP (n=36) was: -0.03 (p=0.86). The correlation coefficient in population with a positive history of PKP (n=16) was: 0.17 (p=0.53).
