Background:Data on the serum vitamin D3levels of vernal keratoconjunctivitis (VKC) children are not known well
in Central Africa. Children with vernalkeratoconjunctivitis are less exposed to sunlight. There
is no study that shows the breadth of the serum vitamin D3 levels of vernal
keratoconjunctivitis children and normal in our setting. Purpose: This
study aimed to compare the serum 25-hydroxyvitamin D [25(OH)D3] levels of children with and
without VKC. Methods: An observational, case-control study was performed
from September 2019 to February 2020 in the Ophthalmology Department and the
Clinical Biology Department of the University Hospital of Kinshasa. The case group was recruited
consecutively in the consultation while the control group was enrolled in the
nearest Rehoboth school complex using a systematic sample method (k = 4) on the
presence register. Both cases and controls underwent the routine
ophthalmological examination of the anterior segment and serum vitamin D3levels
were measured in both cases and controls using Mindray Chimic-Luminescence
(CL)-1200i.Data were entered in Microsoft Sheets and
analyzed using SPSS version 20.0.The Mann-Whitney-U test (M-U), and the t-Student test w
