Name of the Condition

• Punctate keratitis
• Also known as: Punctate epithelial keratopathy

Summary

Punctate keratitis is an eye condition characterized by small, dot-like lesions on the cornea of the left eye. These lesions can cause discomfort and affect vision if not properly managed.

Causes

• Infections, such as those caused by adenoviruses or herpes simplex virus.
• Prolonged contact lens wear or improper lens hygiene.
• Dry eyes or exposure to environmental irritants.
• Use of certain medications or eye drops.

Risk Factors

• Overuse or mishandling of contact lenses.
• Pre-existing dry eye conditions.
• Exposure to infectious agents or harsh environmental conditions.
• Previous eye injuries or surgeries.

Symptoms

• Eye redness and irritation.
• Watery eyes or excessive tearing.
• Sensitivity to light (photophobia).
• Blurred or reduced vision.
• Foreign body sensation in the eye.

Diagnosis

• Comprehensive eye examination by an ophthalmologist.
• Use of special eye stains (e.g., fluorescein) to highlight corneal lesions.
• Visual acuity tests and slit-lamp examination.

Treatment Options

• Artificial tears and lubricants: Help alleviate dryness and discomfort.
• Antiviral or antibiotic eye drops: Used if an infection is present.
• Patching or bandage contact lenses: May offer temporary relief from symptoms.
• Anti-inflammatory medications: To reduce swelling and irritation.

Prognosis and Follow-Up

• With appropriate treatment, symptoms often improve within a few days to weeks.
• Regular follow-up with an eye care professional is crucial to monitor healing and prevent recurrence.

Complications

• Persistent discomfort or chronic dry eye syndrome.
• Corneal scarring leading to vision impairment.
• Increased risk for secondary infections.

Lifestyle & Prevention

• Maintain proper contact lens hygiene and reduce wear time.
• Use protective eyewear in harsh environmental conditions.
• Stay well-hydrated and use humidifiers to maintain moisture levels.
• Regular eye check-ups to catch early signs of corneal issues.

When to Seek Professional Help

• Sudden or severe eye pain.
• Rapid loss of vision.
• Persistent redness or discharge that does not improve with over-the-counter treatments.

• Take note of any underlying causes noted in patient records that might impact coding.
• Verify all symptoms and treatment documentation to ensure comprehensive coding accuracy.
