What causes sweaty eyes

Many people will find that their eyes sweat. In fact, this situation is not because the eyes sweat due to hot weather. In addition, eye secretions increased and tears appeared. This symptom is usually caused by conjunctivitis. Patients can go to the hospital for relevant treatment. It is very easy to determine whether you have conjunctivitis. You can make your own judgment by understanding the symptoms of conjunctivitis.

Clinical manifestations

Conjunctival congestion and increased secretions are common characteristics of various conjunctivitis. The inflammation can occur in one eye or both eyes simultaneously/sequentially.

1. Symptoms

The affected eye may experience a foreign body sensation, burning sensation, heavy eyelids, and increased secretions. When the lesion involves the cornea, photophobia, tearing, and varying degrees of vision loss may occur.

2. Physical signs

The signs of conjunctivitis are an important basis for the correct diagnosis of various conjunctivitis.

(1) Conjunctival congestion The characteristic of conjunctival vascular congestion is that the closer to the dome, the more obvious the congestion. The blood vessels are distributed in a reticular manner, bright red in color, and can extend into the periphery of the cornea to form corneal pannus.

(2) Purulent discharge is common in gonococcal conjunctivitis; mucopurulent or catarrhal discharge is common in bacterial or chlamydial conjunctivitis, and often adheres firmly to the eyelashes, making it difficult to open the eyelids in the morning; watery discharge is usually seen in viral conjunctivitis.

(3) Conjunctival edema. Conjunctival inflammation causes conjunctival blood vessel dilation and exudation, leading to tissue edema. Because the bulbar conjunctiva and fornix conjunctiva tissues are loose, they bulge out significantly when edematous.

(4) Subconjunctival hemorrhage is mostly in the form of dots or small patches. Epidemic hemorrhagic conjunctivitis caused by viruses is often accompanied by subconjunctival hemorrhage.

(5) The papilla is a nonspecific sign of conjunctival inflammation and can be located on the palpebral conjunctiva or corneal limbus. It presents as a raised polygonal mosaic appearance with areas of hyperemia separated by pale grooves.

(6) Follicles Follicles are yellow-white, smooth, round protrusions with a diameter of 0.5 to 2.0 mm. However, in some cases, such as chlamydial conjunctivitis, larger follicles may also appear. Viral conjunctivitis and chlamydial conjunctivitis are often accompanied by obvious follicle formation and are called acute follicular conjunctivitis or chronic follicular conjunctivitis.

(7) Membrane and pseudomembrane Membrane is a cellulose exudate attached to the surface of the conjunctiva. Pseudomembrane is easy to peel off, while true membrane is not easy to separate. After forced peeling, the wound will bleed. The essential difference between the two lies in the difference in the degree of inflammatory response. The inflammatory response of true membrane is more severe. Corynebacterium diphtheriae causes severe membranous conjunctivitis; β-hemolytic streptococci, Klebsiella pneumoniae, gonococci, adenovirus, inclusion bodies, etc. can all cause membranous or pseudomembranous conjunctivitis.

(8) Damage to scar matrix tissue is the histological basis of conjunctival scar formation. Early manifestations of conjunctival scarring include narrowing of the conjunctival fornix and subepithelial fibrosis of the conjunctiva.

(9) Swollen preauricular lymph nodes Viral conjunctivitis is often accompanied by swollen preauricular lymph nodes.

(10) Pseudoptosis is caused by hypertrophy of the upper eyelid tissue due to cell infiltration or scar formation, resulting in mild ptosis, which is more common in the late stage of trachoma.

(11) Conjunctival granuloma is less common and can be seen in chronic inflammation caused by tuberculosis, leprosy, syphilis and rickettsia.
