Combining break-up time and Rose bengal scores improves predicting treatment effectiveness for dry eye disease (keratoconjunctivitis sicca). This combined approach offers clinical value where individual tests fall short.

Area of Science:

  • Ophthalmology
  • Clinical Medicine
  • Diagnostic Testing

Background:

  • Keratoconjunctivitis sicca (dry eye disease) diagnosis and treatment monitoring can be challenging.
  • Existing diagnostic tests like tear break-up time and Rose bengal staining have limitations in predicting treatment response individually.

Purpose of the Study:

  • To evaluate the combined predictive value of tear break-up time and Rose bengal score for treatment effect in keratoconjunctivitis sicca.
  • To determine if a combined analysis offers superior clinical utility compared to individual tests.

Main Methods:

  • Partial regression analysis was employed.
  • Data from 35 patients with varying severity of keratoconjunctivitis sicca were analyzed.
  • Tear break-up time values and Rose bengal scores were correlated with treatment outcomes.

Main Results:

  • Individual tests (break-up time, Rose bengal score) showed significant scatter and were poor predictors of treatment effect.
  • Analyzing break-up time and Rose bengal score together in a partial regression model yielded an adequate prediction of treatment effect.
  • The combined analysis demonstrated clinical value in predicting treatment outcomes.

Conclusions:

  • Neither tear break-up time nor Rose bengal score alone reliably predicts treatment effectiveness in keratoconjunctivitis sicca.
  • A combined analysis of these diagnostic measures provides a clinically valuable prediction of treatment response for dry eye disease.
