To determine the anterior-posterior diameter of both eye balls by use of magnetic resonance imaging (MRI) and to find out possible association between the ocular anterior-posterior diameter with inter-zygomatic length, age and sex of healthy individuals.
Retrospective study of ocular APD and inter zygomatic length (IZL) was carried out in Department of Radiology. About 403 cases with normal MRI findings of brain and orbit were retrospectively analyzed by two senior radiologists independently keeping in view of inter observer variability. Study includes T2 weighted axial imaging of brain and orbit from January 2017 to Jan 2019. Data were analyzed using SPSS software version 22.0 for Microsoft Windows 10.
The normal anterior-posterior diameter of the right and left globe of male person were 22.97 ± 0.946 mm and 22.94± 0.928 respectively. The normal anterior-posterior diameter of the right and left globe of female person were 22.48 ± 0.919 mm and 22.42± 0.921 respectively. The IZL was 97.6±4.297 and 94.05±4.277 in male and female individual respectively. Male individuals had higher ocular APD and IZL than female individuals (P < 0.001).
The normal ocular APD will help the clinicians, ophthalmologists and radiologist to quantitatively evaluate patients with abnormal ocular size and/or refractive errors.
