Keratitis

Definition:

Keratitis refers to the inflammation of the cornea, which is the clear, dome-shaped front surface of the eye. It can occur as a result of various causes, including infections, injuries, or underlying conditions. Keratitis can be painful and may lead to vision impairment or even permanent vision loss if left untreated.

Causes of Keratitis:

• Infections: Bacterial, viral, or fungal infections can lead to keratitis. Examples include herpes simplex virus (HSV) keratitis, bacterial keratitis, or fungal keratitis.
• Injury: Trauma to the cornea, such as scratches, cuts, or foreign body intrusion, can cause keratitis.
• Underlying conditions: Certain underlying conditions, such as dry eyes, autoimmune diseases, or reduced tear production, can increase the risk of developing keratitis.
• Contact lens wear: Improper use or maintenance of contact lenses can introduce bacteria or irritants to the eye, leading to contact lens-related keratitis.

Symptoms of Keratitis:

• Eye redness
• Eye pain or discomfort
• Blurred or hazy vision
• Sensitivity to light (photophobia)
• Excessive tearing
• Inflammation or swelling of the eye
• Foreign body sensation
• Watery or purulent discharge from the eye

Treatment of Keratitis:

The treatment approach for keratitis depends on the cause and severity of the condition. It may involve:

• Prescription eye drops or ointments to reduce inflammation and fight infection
• Oral medications in severe cases
• Removal of foreign bodies or debris from the eye
• Management of underlying conditions contributing to keratitis
• Close monitoring and follow-up with an eye care professional
• In some cases, surgery or corneal transplantation may be necessary

It is important to seek prompt medical attention if you experience symptoms of keratitis to prevent complications and preserve your vision.
