Viral conjunctivitis

The main symptoms of viral conjunctivitis are some symptoms that appear during the incubation period of seven to twelve days, mainly conjunctival congestion and watery secretions, and some swelling symptoms of the upper and lower eyelids before going to bed. In daily life, the main symptoms are corneal bleeding. Severe viral conjunctivitis has some backlighting and foreign body sensation, which are mainly caused by viral invasion. Secondary bacterial infection is also relatively common.

Viral conjunctivitis is also a common conjunctivitis. The main treatment method is cleaning with saline solution and taking some medications. When trying to move, you must prevent infection and develop some hygienic habits. In addition, you must note that viral conjunctivitis is highly contagious.

Patients with severe viral conjunctivitis may complain of significant photophobia and foreign body sensation, and the conjunctival surface of the patient may have fibrinous pseudomembranes and inflammatory cells and/or focal corneal inflammation. Even after conjunctivitis subsides, slit-lamp examination may reveal residual corneal scarring (0.5-1.0 mm) for 2 years or more. This corneal scarring occasionally causes decreased vision and significant glare.

Although viral conjunctivitis can be cultured, special tissue culture equipment is required to grow the virus. Secondary bacterial infection is rare. If any components such as purulent discharge are consistent with bacterial conjunctivitis, bacterial cultures should be obtained. The smear may be examined microscopically and stained with Gram stain to identify bacteria and with Giemsa stain to determine leukocyte reactions.

Viral conjunctivitis is a common conjunctivitis that can be caused by a variety of viruses and can be clinically divided into two groups:

One group: acute follicular conjunctivitis as the main manifestation, including epidemic keratoconjunctivitis, epidemic hemorrhagic conjunctivitis, pharyngoconjunctivitis, herpes simplex conjunctivitis and Newcastle disease conjunctivitis.

One group: manifested as relatively subacute or chronic conjunctivitis, including molluscum contagiosum blepharoconjunctivitis, varicella-zoster blepharoconjunctivitis, measles keratoconjunctivitis, etc. Mild viral conjunctivitis is rapidly self-limiting, while severe cases may cause severe systemic symptoms. Except for the typical cases, the clinical manifestations vary greatly, which is related to the virulence of the pathogenic virus and the individual's immune status.

The above are common phenomena of viral conjunctivitis. There are many things to note. Patients should be isolated and not go to public places to infect others. At this time, their own resistance is also very easy to be infected with some other types of diseases. Therefore, patients should pay attention to rest, eat a light diet, pay attention to hygiene and develop some other good hygiene habits.
