In claims from social law, evaluation by the treating physician is often mandatory. He is obliged to provide information at the request of the social insurance carrier. Ophthalmologists are required to independently and objectively assess medical conditions, apart from a routine visit, and pass the data on to the consultants at the pension office in a understandable way. Functional impairment must be explained on the basis of morphology, diagnosis and examination results so that it becomes impartially comprehensible. Basically, examination results must be presented according to the standards of medical evaluation, such as DIN 58220 visual acuity testing and visual fields analogous to manual-kinetic perimetry by Goldmann perimeter or approved comparable methods of visual field testing. Results that are not compliant with the official standards need to be identified accordingly.
