Abstract
Background
Perfluorohexyloctane (PFHO) acts to prevent the evaporation of the tear film. It has the potential to limit friction related issues between the eye lid margin and the ocular surface. Prior to the present work, this had not yet been evaluated.
Objective
To examine the potential of using perfluorohexyloctane for reducing the signs and symptoms of lid wiper epitheliopathy (LWE).
Methods
Data were collected at 4 visits spanning 2 months. Patients who had symptomatic dry eye and a LWE score of ≥1.0 on the Korb LWE scale were recruited. Participants were randomized to PFHO 4 times a day or no treatment. Lid wiper epitheliopathy was graded at each visit with the Korb and photographic LWE (PLWE) scales. Symptoms were assessed using the Standard Patient Evaluation of Eye Dryness questionnaire and visual analog scales (0–100).
Results
A total of 52 participants were enrolled (mean ± SD age, 49.7 ± 15.7 years; 79% female). Right eyes in the treatment group were significantly more likely to show an improvement of ≥0.5-units in PLWE scores at 2 months than the no treatment group (P = 0.04), but no left eye differences were noted. Korb and PLWE scores were significantly better in the treatment group compared with the no treatment group starting at 2 weeks and remained so for the duration of the study (all P < 0.001). Standard Patient Evaluation of Eye Dryness scores and dry eye symptoms were significantly better in the treatment than in the no treatment group at the 2-month visit (all P ≤ 0.01).
Conclusions
Perfluorohexyloctane significantly reduced LWE and improved dry eye symptoms compared with no treatment, suggesting that PFHO may enhance ocular lubrication and reduce friction-related damage. Masked, randomized, trials are still needed to compare PFHO to other treatments in participants with LWE to support generalizability of results. ClinicalTrials.gov study NCT06671041.
期刊介绍:
We also encourage the submission of manuscripts presenting preclinical and very preliminary research that may stimulate further investigation of potentially relevant findings, as well as in-depth review articles on specific therapies or disease states, and applied health delivery or pharmacoeconomics.
CTR encourages and supports the submission of manuscripts describing:
• Interventions designed to understand or improve human health, disease treatment or disease prevention;
• Studies that focus on problems that are uncommon in resource-rich countries;
• Research that is "under-published" because of limited access to monetary resources such as English language support and Open Access fees (CTR offers deeply discounted English language editing);
• Republication of articles previously published in non-English journals (eg, evidence-based guidelines) which could be useful if translated into English;
• Preclinical and clinical product development studies that are not pursued for further investigation based upon early phase results.
