Types of eye infections and symptoms:
Conjunctivitis (Pink Eye)
Conjunctivitis, commonly known as pink eye, is a highly contagious eye infection characterized by redness, itching, and discharge in the eye. The condition can be caused by viruses, bacteria, or allergens. Viral conjunctivitis is often accompanied by a watery discharge, while bacterial conjunctivitis may lead to a yellowish-green discharge. Allergic conjunctivitis, on the other hand, typically causes itching, redness, and tearing.
Stye (Hordeolum)
A stye, or hordeolum, is a common eye infection that occurs in the eyelid. It appears as a red, painful lump near the edge of the eyelid and is often caused by bacterial infection of the oil glands. Styes may be filled with pus and can cause discomfort, swelling, and tenderness in the affected area.
Blepharitis
Blepharitis is a chronic inflammation of the eyelids that can lead to eye irritation, redness, and crusting along the eyelid margins. It is commonly caused by bacterial overgrowth or skin conditions such as seborrheic dermatitis. People with blepharitis may experience itchy eyelids, oil gland dysfunction, and flaky debris on the eyelashes.
Corneal Infections
Corneal infections, such as keratitis, involve inflammation of the cornea and can result from bacterial, viral, or fungal infections. Symptoms may include eye pain, redness, blurred vision, and sensitivity to light. Keratitis is a serious condition that requires prompt treatment to prevent vision loss or complications.
Uveitis
Uveitis is an inflammatory condition affecting the uvea, the middle layer of the eye. It can be caused by infections, autoimmune diseases, or inflammatory disorders. Symptoms of uveitis may include eye pain, redness, blurred vision, and light sensitivity. Prompt diagnosis and treatment are essential to manage uveitis and prevent complications.
