Overview
The authors studied how the eye surface recovers after ptosis or ectropion surgery, looking for factors before surgery that predict incomplete recovery of symptoms. They followed 50 eyes of 32 patients (23 ptosis eyes, 27 ectropion eyes) at two Italian centers, testing the eye surface before surgery and at 1 week, 1 month and 3 months after, using the OSDI symptom questionnaire, the Schirmer tear test, tear breakup time and corneal surface staining.
Findings
- 50 eyes of 32 patients, mean age 73.0 ± 13.9 years, 44% female; 23 ptosis eyes, 27 ectropion eyes.
- Tested before surgery and at 1 week, 1 month and 3 months after.
- At 3 months, OSDI symptom score fell by a median 11.0 points (p < 0.001); Oxford corneal staining score fell by 0.96 grades (p < 0.001).
- Ectropion patients improved more on OSDI than ptosis patients (median 21 vs. 2 points, p = 0.002) but reached similar final scores (median 16 vs. 18, p = 0.715).
- Pre-existing dry eye disease found in 10 of 32 patients (32%), all with severe baseline disease.
- 100% of patients with pre-existing dry eye reached the minimal clinically important symptom improvement, versus 33% of patients without it (p < 0.001).
- 50% of patients with pre-existing dry eye still had moderate symptoms (OSDI ≥ 23) at 3 months, versus 19% of those without it (p = 0.105).
- Overall course was biphasic: symptoms briefly worsened at 1 week, then improved progressively to 3 months.
What it means for a patient
- Surgery to fix a droopy eyelid (ptosis) or an outward-turning eyelid (ectropion) tends to make the eye surface feel better within 3 months, though it may feel worse in the first week.
- A patient with pre-existing dry eye before surgery still gets a meaningful improvement, but is more likely to still have moderate eye-surface symptoms 3 months out.
- This information supports counseling patients with severe dry eye beforehand on realistic expectations and possibly more intensive perioperative eye-surface care, though the authors say this needs to be tested in a randomized trial.
- Findings come from 50 eyes at two centers, not a large multi-center trial.
Why this paper matters
It measures, with numbers, how much the eye surface improves after ptosis and ectropion surgery, and shows that pre-existing dry eye disease predicts a higher chance of lingering, though still improved, symptoms.
Terms
- OSDI (Ocular Surface Disease Index): a patient questionnaire scoring dry eye symptoms.
- Schirmer I test: a strip-of-paper test measuring tear production.
- Tear breakup time (NI-BUT): how long the tear film stays intact over the eye before it breaks up.
- Oxford staining score: a scored measure of dye staining on the corneal surface, indicating surface damage.
- Ectropion: the eyelid margin turning outward, away from the eye.
- Minimal clinically important difference: the smallest symptom-score change patients notice as meaningful.
