[Temporary vision disorders, accentuated by deficient illness adjustment].

A medical expert's opinion had to be given on five patients complaining about temporary visual disturbances. 1. Haze caused by keratoconjunctivitis sicca; 2. changing refraction related to diabetes; 3. phosphenes in a paralyzed monoculus; 4. double vision with fatigue in myasthenia; 5. presumed elevation of the risk for accidents in congenital nystagmus. The loss of earning capacity in these cases should be calculated as the mean of the earning capacity during the phases of least and maximal disturbance, if it is not yet included in the loss caused by additional stationary defects. Psychological adaptation to or an additional disturbance by the disease has to be considered and may justify a higher loss of earning capacity.
