Summary
Reduced corneal sensitivity and poor tear function are linked to recurrent corneal erosion syndrome (RCES) after trauma. Improvement in these functions may decrease RCES recurrence.
Area of Science:
- Ophthalmology
- Corneal Disease
- Ocular Surface
Background:
- Posttraumatic recurrent corneal erosion syndrome (RCES) significantly impacts ocular health.
- Understanding factors influencing RCES prognosis is crucial for effective management.
Purpose of the Study:
- To investigate the association between corneal sensitivity, tear function, and the prognosis of posttraumatic RCES.
- To compare outcomes between diseased and healthy fellow eyes.
Main Methods:
- Retrospective enrollment of 31 patients with unilateral RCES and ocular trauma history.
- Corneal sensitivity, tear break-up time, and Schirmer test performed at 3 intervals post-trauma.
- Patients categorized into Group A (>2 recurrences) and Group B (2 recurrences).
Main Results:
- Diseased eyes exhibited lower corneal sensitivity and tear function (tear break-up time, Schirmer test) compared to fellow eyes in both groups.
- Group B showed recovery of corneal sensitivity and Schirmer test values over time.
- Corneal sensitivity and tear function were diminished in eyes with RCES.
Conclusions:
- Impaired corneal sensitivity and tear function are associated with posttraumatic RCES.
- Recovery of corneal sensitivity and tear function may correlate with reduced RCES recurrence.
