Abstract
INTRODUCTION: The aim of this observation study was to determine whether regression of lid-parallel conjunctival folds (LIPCOF) can be induced by repeated and intensive treatment with a gel-forming tear substitute. METHODS: In cooperation with the referring ophthalmologists, patients suffering from advanced dry eye condition were recruited. LIPCOF grades from 1 to 3 were included. Tear film break-up time (BUT) had to be less than 10 sec and the Schirmer-I test less than 10 mm. All patients recruited had been using watery tear substitutes. Examinations including visual acuity, slit lamp, fluorescein test, Schirmer-I test, BUT, LIPCOF were performed at baseline and after 2 weeks and 2 months. All examinations were done by the same physician at the Dietrich-Bonhoeffer Eye Hospital of Neubrandenburg. Exclusion criteria were severe eye diseases such as glaucoma, cataract, retinal detachment, history of intraocular or conjunctival surgery and disorders of the eye lids. Pretreatment with gels was not allowed. In the study, patients were treated with Liposic Eye Gel at least three times a day for a period of two months. RESULTS: LIPCOFs regressed in 10 eyes of 5 patients (1 x male, 4 x female) from a mean grade of 2.58 at baseline to 2.29 after 2 months under Liposic treatment. This improvement is statistically significant (n = 10, p = 0.04). Schirmer-I test results had improved in the same time period from a mean of 6.4 mm at baseline to a mean of 8.1 mm after 2 months (n. s., n = 10, p = 0.73). BUT improved from a mean of 12.5 sec at baseline to a mean of 17.5 sec at the 2-month follow-up (n. s., n = 10, p = 0,085). In one patient the cornea was fluorescein-positive at baseline and stayed so throughout the follow-up. Liposic Gel was used by the patients between 3 to 8 times per day. Tolerance was excellent. DISCUSSION: The study results show that the morphological signs of the dry-eye condition like LIPCOFs can be reversed by intensive treatment with Liposic Gel. The improvements in BUT and Schirmer-I test results confirm the adherence of the patients to the treatment schedule. CONCLUSION: This pilot study provides the statistical data necessary for designing a major treatment study to prove not only the reversibility of LIPCOF, but also the dependence of the possible improvement on the grade of LIPCOF stage on the age of the patient and on other criteria.
