Reflex Conjunctival

Description:

The conjunctival reflex or conjunctival reflexes are **a set of reflex changes in the vascular pattern and reactions of tear fluid to pressure on the eyeball** with the eyelids closed. Reflexes appear when the sensitive nerve endings of the conjunctiva, which are located on the nasal surface of the eyeball, are irritated. Conjunctival reflexes are measured by applying pressure to the eye with the eyelids closed. The nature of the reflex reaction indicates the state of the parasympathetic, sympathetic nervous system of the eye, the state of all links in the reflex arc chain. A change in the conjunctival reflex is possible with corneal ulcers, tuberculous blepharitis, purulent conjunctivitis, tumors of the inner lining of the fundus, etc.

In the normal state of the autonomic nervous system, the reflex reaction of the conjunctiva is assessed when exposed to various factors and under various conditions. It should be noted that some researchers still do not recognize the need for this reflex. But from the point of view of modern ophthalmology, diagnosis is extremely important; it is more informative and reliable than different examination methods. How to measure the conjunctival reflex
