Ocular Anatomy

By Dr. Dinesh Kumar Ramesh Chandra

The eyes are one of the most complex and highly specialized sensory organs in our body. It is about 1 inch in diameter and has a volume of about 3-4 cc. They are situated within the large bony sockets called orbital cavity. The cavity is formed by 7 bones namely maxilla, palatine, zygomatic, sphenoid, frontal, ethmoid and lacrimal bone.

The eye ball is located beneath the forebrain and above the maxillary sinus. Each eye has 6 muscles attach to it and is protected by the eyelids and the tough bony orbital rim.

It is very important that we take care of our eyes by practicing good eating habits and going for regular check-ups. Please do not take your eyes for granted as damage to the eyes can be permanent or irreversible. So, go for a comprehensive eye examination today.

The image below shows the 6 muscles attached to the eyes.(4 rectus muscle and 2 oblique muscle) which is responsible for the various eye movements.
