Ocular fluorometry: standardization and instrumentation development. A Concerted Action in the European Community (EUROEYE)

A Concerted Action on Ocular Fluorometry, stressing standardization and instrumentation development has been funded by the European Community. Agreement was reached on harmonization of protocols. The results obtained show that the protocols proposed for Clinical Ocular Fluorometry were generally appropriate and may be followed closely, with reproducible and meaningful results. In each group, areas for improvement could, however, be detected, particularly regarding facility of use of the newly developed softwares. The success of the ECNOF was very rewarding and every effort is being made to consolidate this success in the publication and dissemination of the agreed guidelines and results. The field of Ocular Fluorometry appears to have even more potential than was apparent at the beginning of this Concerted Action. The needs for instrumentation development have been clarified and four main directions where progress has been achieved are identifiable: spectral fluorescence analysis of naturally occurring ocular fluorophores, light scattering analysis of ocular structures and fluids, improved axial resolution for better quantification of ocular permeabilities and, finally, development of simple routine clinical instrumentation. Corneal and lens natural fluorescence appear extremely promising as indicators of disease status, particularly in diabetes. Blood-retinal barrier permeability has the potential to become a screening test isolating the eyes at risk for developing diabetic blindness and, therefore needing closer follow-up and earlier treatment. Light scattering methodologies particularly in association with ocular fluorometry, may allow improved monitorization of chronic inflammation, better therapeutical management of a variety a sight-threatening diseases.
