The Effect of Ocular Lubricant Eyedrops on Lid Parallel Conjunctival Folds and Other Signs and Symptoms of Dry Eye

• Status: Completed
• Trial end date: 2010-02-01
• Target enrollment: 0
• Participant gender: All

Summary

Purpose To try to establish whether lid-parallel conjunctival folds (LIPCOF) can be influenced by increased lubrication with rewetting and lubricating eyedrops containing hydroxypropyl-guar, which has proven lubricating effect.

Methods During summer and fall of 2009, 16 ophthalmologists from various regions of Croatia investigated the effect of topical therapy with lubricating eyedrops on the signs and symptoms of dry eye, with the special emphasis on lid-parallel conjunctival folds (LIPCOF). 229 patients were enrolled in the study.

Results After 14 days of therapy with lubricating eyedrops containing hydroxypropyl-guar, statistically significant reduction of LIPCOF grade was observed, as well as the reduction of symptoms and other signs of dysfunctional tear syndrome (TBUT, Schirmer test, conjunctival hyperemia).

Conclusion Results of this study have shown positive influence of lubricating eyedrops containing hydroxypropyl-guar on signs and symptoms of dysfunctional tear syndrome even after only 14 days of treatment. It is of particular interest that LIPCOF grade was statistically significantly decreased, pointing at increased friction and decreased ocular surface lubrication as possible causes of its appearance.

Having this in mind, every clinician involved in dysfunctional tear syndrome treatment must also think about lubrication as integral part of treating this condition.

Criteria

Inclusion Criteria:

Ocular foreign body sensation, burning or stinging, complaints more pronounced in winter, windy conditions, during computer work, being bilateral, of the duration longer than three months, visual acuity fluctuations depending on blinking after longer reading or computer work, and tearing in cold weather, in the morning, after longer reading or computer work. Patients were also asked whether the symptoms were more pronounced in the morning or evening. The main enrollment criterion was the score of the above listed symptoms 15 or higher.

Exclusion Criteria:

Pregnant women, children, chronic eye patients on continuous topical therapy during previous month (i.e.glaucoma) and patients suffering from any acute eye disease and therefore on topical or systemic therapy in the previous month were excluded from the study.
