Viral eye infections can cause discomfort and blurred vision. Depending on the site and form of infection that develops, the doctor might provide a drop to lessen the discomfort.
Close look on the different types of viral eye infections
Viral conjunctivitis or pink eye occurs if the conjunctiva which is the transparent tissue covering the white part of the eye and lines the underside of the eyelids turns red due to a virus. There is also irritation, itchiness and drainage from the eye. In addition, the eyelids are swollen along with light sensitivity.
The condition is generally due to common cold and can easily spread to others. In most cases, the doctor might allow the virus to settle on its own. In severe cases, a steroid eye drop might be prescribed by the doctor to lessen the symptoms.
Generally, ocular herpes affects the cornea. The herpes simplex virus is known to cause the formation of cold sores on the face as well as trigger a viral eye infection.
In most instances, the condition causes redness, light sensitivity, discomfort and visual changes. If the infection involves the deep layers of the cornea, scarring is likely and can cause lasting damage to vision.
A corneal ulcer or open wound on the cornea might be due to a virus or complication from ocular herpes. The wound might also stem from an eye injury and a virus might infect the ulcer.
The usual indications include irritation, pain, excessive tearing and light sensitivity. When looking in a mirror, there is a white, foggy region on the cornea which indicates an ulcer.
The doctor will prescribe an eye drop to deal with the cause of the ulcer. A bandage lens might be recommended which covers the open ulcer. This works by reducing the discomfort as well as promote healing.
