  1. The values are divided in the total sample and the three different visual acuities. It becomes clear that total direct costs, direct medical and direct non-medical cost increase with a lower visual acuity apart from the visual acuity >0.3 to the visual acuity ≤0.3 - >0.1. Concerning the intangible costs of the different caregivers, it gets clear, that there is no significant strain difference
