Corneal abrasion and perioperative eye injury
Stem
A 62-year-old woman, 74 kg, had a 4-hour robotic hysterectomy in steep Trendelenburg with her eyelids taped. Forty minutes into recovery she reports severe pain in her left eye, as if sand is in it, with tearing and light sensitivity; she rubbed her eyes vigorously on waking while still on face-mask oxygen. Her vision is slightly blurred on the left.
Question
What is the likely diagnosis, and how do you manage her?
Ideal answer
HeadlineMost likely a corneal abrasion, but I exclude sight-threatening causes first, then treat the pain and tell her what happened.
- Check acuity, pupils and redness in both eyes, because a fixed or irregular pupil, or visual loss, is not an abrasion and needs urgent ophthalmology.1
- Fluorescein stain under blue light, because it confirms the epithelial defect; a drop of topical anesthetic allows the examination.
- Antibiotic ointment and NSAID analgesia, because most abrasions heal within 24–72 hours; topical diclofenac 0.1% reduces pain and photophobia.1
- Ophthalmology review if not better by 24–48 hours, or sooner for worsening pain or vision.1
- Disclose, document and follow up, because it is a complication of her anesthetic care and she will remember the pain.
Watch for: worsening vision, a fixed mid-dilated pupil, hyphema, or pain still present after 48 hours.
Breaking down the answer
- Why it happens — anesthesia abolishes the blink reflex and reduces tear production; injury comes from exposure, rubbing, masks, drapes, badges or the laryngoscope.1 Changes if: the eye was dry and exposed, then exposure keratopathy is the mechanism.
- Risk factors — general anesthesia, age, procedures over 1 hour, prone or Trendelenburg position, blood loss and oxygen in recovery.1 Laparoscopic hysterectomy carried about four times, and robotic about 6.5 times, the risk of open surgery.2
- Differential that changes everything — chemical injury from prep solution, and posterior ischemic optic neuropathy after long cases with blood loss, hypotension or hypoxia;1 acute angle-closure glaucoma gives a hard eye and a mid-dilated pupil.
- Topical anesthetic at home — traditionally forbidden for delayed healing and misuse; a 2016 guideline cited in the review allows tetracaine every 30 minutes for the first 24 hours.1 I prescribe oral and topical NSAIDs and leave dispensing to ophthalmology.
- How common — reported rates span 0.02% to 59% depending on protection; the pooled rate is about 0.64%, and it is the most common perioperative eye injury in closed claims.1
Follow-up question
Your quality committee notes that corneal abrasions doubled after the robotic program began, and the chair asks you to fix it. What do you propose?
Follow-up answer
HeadlineThis is a measurable, preventable harm; I propose a standardized eye-protection bundle with education and audit.
Baseline rate per 1000 anesthetics by procedure and position, then a bundle: lids closed and covered with bio-occlusive dressings or tape at induction, protection kept on until the patient is awake, no face-mask oxygen in recovery unless needed, and staff taught to watch for eye rubbing.1 Bio-occlusive dressings had the lowest reported rate, 0.02%, versus 59% with manual closure.1 One improvement program halved its injury rate, from 1.51 to 0.79 per 1000.1 I re-measure quarterly and report back.
Pitfalls that cost points
- Checking only the upper eye in the lateral position; lateral and prone positioning are independent risk factors.1
- Skipping disclosure because "it heals in two days"; patients recall this pain vividly, and eye claims are common.
- Relying on lubricating gel alone; one trial found a polyacrylic gel caused the most epithelial abnormalities in prone patients.1
Rapid-fire
Q: Classic symptoms? A: Eye pain, foreign-body sensation, tearing, redness, photophobia and blurred vision, usually in the early postoperative period.1
Q: Which anesthetic carries most eye injuries in closed claims? A: General anesthesia, 83%, then monitored anesthesia care 11% and regional blocks 7%.1
Q: Share of anesthesia malpractice cases involving the eye? A: About 3–8%.1
Q: How long does healing take? A: Usually 24–48 hours, almost always under 72; failure to heal by 72 hours needs ophthalmology.1
