Abstract |
PURPOSE Although a number of clinical parameters are well known to affect dry eye (DE) disease, it is unknown which factor mostly affects the discomfort of DE. Blepharitis is recognized as one of the leading causes of evaporative-type DE disease, but there have been no large-scale study to investigate the effect of blepharitis on DE symptoms. The purpose of this study was to evaluate the factors influencing subjective ocular discomfort in DE patients with blepharitis and to determine which parameter is most highly related to severity of blepharitis. METHODS: This investigation was a cross-sectional, clinical study. The test population consisted of DE patients suffering from moderate blepharitis. Seventy-three subjects aged 22 to 81 years (mean age 56.36) were enrolled, 49 of whom completed the investigation on a total of 49 eyes. A detailed assessment was conducted, including history taking, visual analog scale (VAS) pain scoring, ocular surface disease index (OSDI) questionnaire, blepharitis severity grading (score 0-4), conjunctival, corneal fluorescein staining (score 0-4), and tear break up time (TBUT) assessment. RESULTS: The results revealed significant correlations between subjective symptoms and blepharitis severity. Significant increases in overall VAS score, OSDI score (p = 0.031, p = 0.006) were recorded in DE patients with severe blepharitis. Conjunctival erosion was significantly related to VAS score (p = 0.016). Other parameters were not significantly related with VAS and OSDI scores. Additionally, conjunctival erosion was related with blepharitis severity (p < 0.0001), and corneal erosion was not correlated with blepharitis severity. TBUT also did not show any statistical correlation with blepharitis. CONCLUSIONS: Our results showed that blepharitis severity is the main factor influencing subjective pain and discomfort in DE patients, although blepharitis severity was not related with the known clinical parameters of DE such as corneal erosion and TBUT. This study indicates that targeting treatment for blepharitis can significantly improve quality of life for patients suffering from DE disease. |
