A Cross Sectional Study to Determine Periocular Parameters in Newborns At Different Gestational Age

Abstract

Background: A nomogram of periocular measurements of newborn babies has its clinical implication in delineation
of many syndromes.
Aim: To measure periocular parameters like inner canthal distance (ICD), outer canthal distance (OCD), inter
pupillary distance (IPD) in newborns at different gestational age which will help in clinical evaluation of hypo and
hypertelorism.
Materials &Methods: This is a hospital based observational, cross-sectional study in a secondary care hospital of
West Bengal. The study was carried among 250 newborns with gestational period ranging from 32 weeks to 42
weeks who were born in obstetric department of the hospital during a period of 8 months. Ocular dimensions in
newborns at different gestational age groups were measured on day 2, and the values are presented as mean +/- SD
values for different gestational age groups. The data was collected by using structured schedule and was entered
in the Microsoft excel sheets and statistically analysed by SPSS 24.0 and Graph Pad Prism version 5. Results: No
significant difference noted between values of boy and girl babies. The values of different eye measurements have
shown a positive correlation with gestational age and birth weight. To the best of our knowledge, till date there
is only one such study from India.
