H02.05 Trichiasis without entropion

Name of the Condition

• Trichiasis without entropion

Summary

Trichiasis is a condition where eyelashes grow inward toward the eye, irritating the cornea and conjunctiva. This occurs without entropion, a condition where the eyelid itself turns inward. The misdirected lashes can cause discomfort and potential damage to the eye surface if left untreated.

Causes

Trichiasis can result from chronic inflammation, infection, eye trauma, or be idiopathic (no known cause). It may also develop secondary to scarring or structural changes in the eyelid.

Risk Factors

• Prior eye infections, such as trachoma
• Chronic blepharitis (inflammation of the eyelid)
• Eye trauma or surgeries
• Autoimmune conditions affecting the eyes
• Aging-related eyelid changes

Symptoms

• Redness and irritation in the eye
• Persistent sensation of a foreign body in the eye
• Tearing or watery eye
• Sensitivity to light
• Possible corneal damage if untreated

Diagnosis

Physical examination by an ophthalmologist or optometrist. Slit-lamp examination to assess eyelash position and eye surface. Evaluation to rule out entropion or other eyelid abnormalities.

Treatment Options

• Epilation: Temporary removal of misdirected lashes
• Electrolysis or laser treatment: Permanent follicle destruction
• Cryotherapy: Freezing technique for lash removal
• Surgery: Realignment of eyelash growth or eyelid margin adjustment

Prognosis and Follow-Up

With appropriate treatment, symptoms typically improve, and further damage to the eye can be prevented. Follow-up may be needed to monitor for recurrence or complications.

Complications

• Corneal abrasions or ulcers
• Infection
• Vision impairment if corneal damage occurs
• Chronic eye irritation

Lifestyle & Prevention

• Avoid rubbing the eyes to prevent further irritation
• Maintain good eyelid hygiene to reduce inflammation
• Protect the eyes from trauma or foreign objects
• Seek prompt treatment for eye infections or inflammation

When to Seek Professional Help

• Persistent eye irritation or discomfort
• Visible misdirected eyelashes
• Signs of corneal damage (e.g., pain, blurred vision)
• Recurrence after treatment

Tips for Medical Coders

• Use H02.05 for trichiasis without entropion. Ensure documentation specifies the absence of entropion to distinguish from combined conditions. Verify eyelid or eye laterality if applicable for more specific codes.
