Periorbital cellulitis

Periorbital cellulitis is an infection of the skin and tissues surrounding the eye. This condition is also known as preseptal cellulitis. It is a common and potentially serious infection that can affect individuals of all ages, but is most common in children.

Causes

Periorbital cellulitis is usually caused by a bacterial infection. The most common bacteria that cause this condition are Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus. These bacteria can enter the skin and tissues around the eye through a break in the skin, such as a cut, scratch, or insect bite. In some cases, the infection can spread from a nearby site, such as the sinuses.

Symptoms

The main symptoms of periorbital cellulitis include redness, swelling, and tenderness around the eye. Other symptoms can include fever, pain, and a general feeling of being unwell. In severe cases, the infection can spread to the eye itself, causing orbital cellulitis, which is a more serious condition that can lead to vision loss.

Diagnosis

Periorbital cellulitis is usually diagnosed based on the symptoms and a physical examination. In some cases, a blood test or imaging tests such as a CT scan or MRI may be needed to confirm the diagnosis and rule out other conditions.

Treatment

Treatment for periorbital cellulitis usually involves antibiotics to fight the bacterial infection. In severe cases, hospitalization and intravenous antibiotics may be needed. It is important to start treatment as soon as possible to prevent complications.

Prevention

Prevention of periorbital cellulitis involves good hygiene practices to prevent skin infections, such as washing hands regularly and treating cuts and scratches promptly. Vaccination against Streptococcus pneumoniae and Haemophilus influenzae can also help prevent these infections.
