Abstract Details

Purpose:

To analyze the correlation between Ocular Surface Disease Index (OSDI) questionnaire score and average bulbar redness (BR) measured by Keratograph 5M(K5M) in limbal stem cell deficiency (LSCD) patients.

Setting:

We studied LSCD patients diagnosed according to Dua clinical criteria belonging to the Ocular Surface Unit of Virgen Macarena and Virgen del Rocio Hospitals (Seville, Spain).

Methods:

38 patients (76 eyes) were analyzed with a mean age of 54.63 years. Each subject completed OSDI questionnaire and an ocular surface evaluation was performed by K5M. OSDI (0 to 100 points) is a questionnaire that measures ocular surface symptoms and its patient's daily life impact. The K5M detects and automatically classifies bulbar, limbal and average redness (from 0 to 4), with a high inter- and intra repeatability. OSDI score and average BR were analyzed using Pearson correlation coefficient to establish whether there was a relationship between them.

Results:

Means were 47.5 (25.8) for OSDI score and 1.72 (0.78) for average BR. Pearson correlation coefficient showed no linear relationship between both variables (r = 0.097; p = 0.453).

Conclusions:

OSDI and average BR measured by K5M are not correlated in LSCD patients.
