Corneal ulcers are a serious eye condition that can lead to permanent vision loss if not treated promptly. In Karachi, where environmental factors like dust, humidity, and contact lens use are common, understanding the causes and symptoms of corneal ulcers is essential for protecting your eyes.
What Are Corneal Ulcers?
A corneal ulcer is an open sore on the cornea — the transparent front layer of the eye. It typically develops due to infections from bacteria, viruses, fungi, or parasites. Injuries to the eye, such as scratches from foreign objects or improper contact lens use, can also allow harmful microorganisms to enter and cause an ulcer.
Common Causes
- Bacterial infections – Often linked to contact lens wear, especially overnight use.
- Viral infections – Such as herpes simplex virus, which can reactivate over time.
- Fungal infections – More common in warm, humid climates and agricultural settings.
- Trauma or injury – Even minor scratches can lead to ulcers if untreated.
- Dry eyes or eyelid disorders – Conditions that reduce tear production can increase the risk.
Symptoms to Watch For
Early diagnosis is critical. Signs of corneal ulcers may include:
- Severe eye pain or redness
- Blurred or decreased vision
- Tearing or discharge
- Sensitivity to light
- A white or gray spot visible on the cornea
If any of these symptoms occur, seek immediate professional care to avoid complications.
Treatment Options
Treatment depends on the cause of the ulcer. Common approaches include:
- Antibiotic, antiviral, or antifungal eye drops to target infections
- Pain relief and anti-inflammatory medication to ease discomfort
- Protective eye shields to prevent further injury during healing
- Surgical options, such as corneal transplantation, for severe or unresponsive cases
Prompt medical attention can prevent vision loss and complications.
