The pupillary reaction checked with the help of a torch light, gives a lot of information on the health of the nerve at the back of the eye.
The extra ocular movements of the eyes are synchronised movements which involve many cranial nerves and results in binocular vision and improved range of vision.
The diagnosis of squint (latent or manifest) is made through a set of tests which involve seeing the movement of the eyes.
Forward bulging of the eyes called proptosis is also detected during the external examination of the eyes.
Please Note......
The external examination gives a wealth of information in diagnosing neuro-ophthalmology conditions, squint, pseudo squint, nerve palsies, thyroid eye disease, orbital tumours and much more.
