Eye discharge, or conjunctival discharge. As shown in the figure: Increased eye discharge is often seen in inflammatory conditions of the eye, the most common causes being acute conjunctivitis and chronic dacryocystitis. 1. Conjunctivitis: It is one of the most common diseases of the eye. Conjunctival secretions can be purulent, mucopurulent or plasmacytic. The nature of the discharge varies with different types of conjunctivitis. In bacterial or chlamydial infections, conjunctival secretions tend to be viscous and yellowish-white; mucopurulent secretions can cling to the eyelashes, thus causing the lid margins to stick together, and patients can wake up in the morning and have difficulty opening their eyes; allergic conjunctivitis secretions are viscous and filmy; and viral conjunctivitis secretions are aqueous or plasmacy. Patients with conjunctivitis, in addition to increased ocular discharge, often accompanied by foreign body sensation, burning sensation, itching, tearing and other symptoms, if the lesion involves the cornea, there will also be photophobia, blurred vision and other symptoms. 2, chronic dacryocystitis: is the most common of the lacrimal sac lesions, mostly secondary to nasolacrimal duct narrowing or obstruction, tear retention within the tear sac, accompanied by bacterial infection caused, mostly unilateral onset. Patients with chronic lacrimal sac disease, in addition to excessive eye stool, are often accompanied by tearing and eczema on the skin of the lower lid. When pressing the inner corner of the affected eye, sometimes mucus or mucopurulent secretions flow from the tear dots (chronic lacrimal sac disease can be diagnosed by tear duct flushing examination). 3. Other common eye diseases: hyperemia can also be seen in eye diseases such as keratitis, internal mydriasis, ocular trauma, and lid entropion.
