Assessment of Normal Occular Volume Using Magnetic Resonance Imaging

Abstract

At the level of lens the transverse and AP diameters of right and left eyeballs were measured and the data obtained from the both eye were compared in relation to size, gender and age Results: The mean (mean ± 2 SD) ocular volume for right eye 5967.17 mm3 ± 1064.58 mm3 and for the left eye was 6025.4 mm3 ± 1455.81 mm3. The mean ocular volumes were different for either eyeball and sex (in males the right eye was 6057.79 mm3, left eye was 5980.02 mm3; while in females the right eye was 5829.74 mm3, left eye was 6141.4 mm3). Mean transverse diameter of the eyeball is 22.8 ± 1.1 mm. Mean antero posterior diameter of the eyeball is 22.4 ± 0.9 mm. Conclusion:The human adult eye approximately measures 22.8 ± 1.1 mm (transverse) and 22.4 ± 0.9 mm (axial) with no significant difference between sexes and age groups. These data can be helpful in ophthalmological, oculoplastic, and neurological practice. We noted that males had slightly bigger eyeballs size in comparison to females.
