What is Corneal Ulcer?
A corneal ulcer is an open sore on the cornea, the clear front surface of the eye. It's often caused by an infection and can lead to severe vision impairment if untreated.
Causes of Corneal Ulcers
Common causes include bacterial, viral, fungal, or parasitic infections. Improper contact lens use, eye injuries, and weakened immune systems significantly increase the risk.
Symptoms to Recognize
Symptoms include severe pain, redness, pus or discharge, blurred vision, swelling, itching, and light sensitivity. Prompt recognition and treatment are crucial for recovery.
Diagnosis Techniques
Diagnosis involves examining the eye under a slit lamp. Dyes like fluorescein may be used to highlight the ulcer. A sample may be taken for laboratory analysis.
Treatment Options
Treatment typically includes antibiotic, antifungal, or antiviral medication. In severe cases, surgery may be necessary. Timely intervention can prevent complications such as blindness.
Prevention Strategies
Proper contact lens hygiene, wearing eye protection, avoiding touching the eyes with dirty hands, and early treatment of eye infections can prevent corneal ulcers.
Research and Innovations
Recent advances include the use of collagen cross-linking to strengthen the cornea, novel drug-delivery systems, and the development of artificial corneas for transplantation.
