No corneal reflex

No corneal reflex is a condition in which the eyes do not respond to a stimulus, such as a finger or cotton swab, placed on the cornea. This is usually a sign of damage to the facial nerve or a decrease in the sensation of the cornea. It may also be caused by a lack of tear production, which can lead to dryness and irritation of the cornea. In severe cases, the lack of corneal reflex can lead to vision loss. Symptoms may include decreased blinking, a feeling of pressure in the eye, and pain or discomfort when looking at bright lights.
