Simple Corneal Abrasion

Question 1

What is the typical history associated with simple corneal abrasion?

Answer 1

Sudden onset of eye pain, tearing, and foreign body sensation. History of trauma to the eye, such as scratching or contact lens wear.

Question 2

What are the key physical examination findings in simple corneal abrasion?

Answer 2

Visible defect in the corneal epithelium with fluorescein staining. Conjunctival redness. Normal pupil reaction and absence of hypopyon.

Question 3

What investigations are necessary for diagnosing simple corneal abrasion?

Answer 3

Clinical diagnosis with fluorescein staining and slit-lamp examination. No further investigations typically needed unless complications are suspected.

Question 4

What are the non-pharmacological management strategies for simple corneal abrasion?

Answer 4

Avoid rubbing the eyes. Use protective eyewear to prevent further injury. Rest the eye and avoid contact lenses until healed.

Question 5

What are the pharmacological management options for simple corneal abrasion?

Answer 5

Topical antibiotic drops or ointment to prevent infection (e.g., erythromycin, polymyxin-bacitracin). Lubricating eye drops for comfort. Oral analgesics if needed for pain management.

Question 6

What are the red flags to look for in simple corneal abrasion patients?

Answer 6

Severe pain not relieved by standard treatment. Vision changes or photophobia. Signs of infection: increased redness, discharge, or swelling.

Question 7

When should a patient with simple corneal abrasion be referred to a specialist?

Answer 7

Refractory symptoms or complications. Suspected retained foreign body. Recurrent corneal abrasions. Need for specialized treatment or further evaluation.

Question 8

What is one key piece of pathophysiology related to simple corneal abrasion?

Answer 8

Loss of corneal epithelial cells due to trauma. Leads to exposure of underlying corneal stroma, resulting in pain and risk of infection.
