Diagnosis
An infection of the eye can present itself with typical symptoms, in addition to pus in or on the eye, a painful, reddish eye can also appear. As a layman, it can be difficult to find the cause of a suppurating eye. A visit to a doctor is therefore advisable. In the case of conjunctivitis, a single glance is often enough for the specialist, but he can also carry out special examinations to find the cause
Associated symptoms
In addition to pus in the eye, other symptoms can be seen, especially in inflammation of the conjunctiva. These include an itching or burning sensation, a reddened eye, a foreign body sensation, sensitivity to light and increased lacrimation. Not all of these symptoms are always present when the conjunctiva is infected.
In the case of a barleycorn, swelling of the eyelid may also occur. A small nodule with pustule on the eyelid appears on a reddened background. Pain with pus in the eye usually indicates an inflammation of the eye.
For example, uveitis (inflammation of the vascular skin of the eye) can lead to pain in the eye. Depending on whether the front part of the eye (iritis = inflammation of the iris), the middle part of the eye (cyclitis = inflammation of the ciliary body = middle eye skin) or the back part of the eye (chorioiditis = inflammation of the choroid, retinitis = inflammation of the retina, vitritis = inflammation of the vitreous body) is affected, the pain can be located at different sites. Often, however, the pain is not easily attributable to the entire eye.
In addition, they can radiate into different regions (usually forehead and temple) and thus cause additional headaches. Fever is in most cases a sign of an infection that affects the whole body. At first, the infection occurs at one point, where the skin reddens, swelling and overheating occurs.
When the entire immune system is activated to fight the cause of the infection, fever typically occurs. This helps the body to fight the pathogens. If fever and pus occur in the eye at the same time, there are two possible explanations: There may be a systemic disease (affecting the whole body) (this can be a cold, for example), which leads to fever and at the same time triggers an eye disease with pus formation. The other explanation would be an infection of the eye, which spreads from there and increasingly demands the entire immune system to fight it.
