Purpose: It was the main purpose of this study to investigate the influence of the moistening solution on TBUT measurements in an asymptomatic population.; Methods: An online survey was employed to determine the compliance of Spanish eye care practitioners with the recommended normalized procedure to administer TBUT. For the purpose of examining the clinical relevance of discrepancies from the recommended procedure, a randomized, double-masked, bilateral study was designed in which a micropipette was used to moisten fluorescein strips with a controlled volume of six different solutions, commonly available in the contact lens office, and TBUT was measured in 58 non-dry eye (OSDI < 15) subjects (age from 19 to 32 years).; Results: Results from the online survey revealed that 64% of Spanish practitioners frequently use (or have used) different solutions to moisten fluorescein strips during TBUT assessment. Statistically significant differences in TBUT values were found between the various solutions as a whole (chi(2) = 198.384, p < 0.001), as well as between all solutions when explored pair-wise (all p < 0.001), except for the two saline solutions.; Conclusions: The present findings support the relevance of selecting the appropriate solution when conducting TBUT for the evaluation of the tear film. Deviations from the recommended procedure may result in misdiagnosis of dry eye and unnecessary patient referral. (C) 2015 British Contact Lens Association. Published by Elsevier Ltd.

The Universitat Politecnica de Catalunya, UPC-BARCELONATECH (http://www.upc.edu), is a technical university that teaches engineering, architecture and optometry degrees. RIMA project (http://www.upc.edu/rima) has been created as a meeting point for Communities of Practice (C&P) at UPC-BARCELONATECH in research devoted to teaching and learning methodologies. RIMA project includes Student Portfolio Community of Practice, GTPoE, focused on portfolio design models and templates. The main goal of GTPoE is to help teachers and students in developing portfolios as an authentic and holistic assessment tool in the frame of European Higher Education Area (EHEA) degrees and masters. GTPoE allow teachers and students to show and share works and examples according to Autonomous Learning (AL) level, as well as exchange experiences and results by creating a Decalogue of Good Teaching Practices, to improve students' portfolio performance. This work provides an approximation to research, based on fundamental aspects that a lecturer might consider to include in a student learning portfolio optimised for common activities in engineering and optometry degrees, essentially describing a relation of good practices. Portfolio experience can be easier applied to other subjects once the GTPoE site contains storage of some examples of using the portfolio in subjects in engineering and optometry degrees. This collection will be also very resourceful for other lecturers and students who have to introduce the tool. Generally, portfolio activity assessment is carried out by means of a survey, in which students can identify the strengths and weaknesses to guarantee the continuous improvement of their performance through portfolio development, in a progressive way to integrate academic knowledge and professional skills.
