  1. 1Differences of minimum temperature of equivalent fingers of both feet measured at the same phalange.
  2. 2Thermal measurement upon admission.
  3. 3Thermal values after physiotherapy treatment.
  4. 4 Difference above 0.6°C, defined by Morgan et al. [16] as the upper limit for 95% of the normal population. Analysed by a randomisation test [17], the differences between damaged and healthy eyes are statistically significant (p=0.036).
  5. Cases 1–3. Thermographic measurements of healthy and damaged fingers, legs, wings and eyes of the three clinical cases and the eyes of six healthy Lammergeiers.
