Goggle technique effective in measuring oxygen consumption

A technique using a goggle with an oxygen sensitive material on the inner surface has been demonstrated to be a successful non-contact method for assessing oxygen uptake of the whole anterior eye, in a recent study published in Contact Lens & Anterior Eye.

A team led by Dr Shehzad A. Naroo et al., Life and Health Sciences, Ophthalmic Research Group, Aston University, Birmingham, UK, studied the oxygen depletion of the unrestricted eyes of 10 patients.

Each measurement was conducted over a 3-minute period using a goggle with oxygen sensitive material contained in the inner surface. The goggle was positioned on the eye and the volume in the goggle and bone structure was recorded by water volume displacement and the output corrected to O₂% reduction/cm³. Measurements were taken in both open and closed–eye conditions.

The results demonstrated that the mean oxygen depletion during open eye state was 3.10 ± 1.51 O₂% cm³. Using the goggle proved to be a non-invasive, non-contact technique for the measurement of oxygen consumption.
