Inclusion criteria

for healthy subjects * Men and Women aged 18 and older * Written informed consent * Normal findings in the medical history unless the investigator considers an abnormality to be clinically irrelevant * Normal ophthalmological findings unless the investigator considers an abnormality to be clinically irrelevant Inclusion criteria for macular disease patients * Men and Women aged 18 and older * Written informed consent * Presence of a macular disease (such as dry or exudative age-related macular degeneration, diabetic maculopathy, epiretinal membrane) Any of the following will exclude a subject from the study: * Any opacities (corneal scar, dense cataract) which interferes with the study relevant measurements * Visual acuity \< 0.1 (Snellen)

Design outcomes

Primary

Measure	Time frame	Description
Reproducibility of retinal sensitivity measurements using microperimetry	Two measurement within one week	Two study measurements are scheduled within one week. Test-retest reproducibility will be assessed for retinal sensitivity using the coefficient of repeatability and Bland-Altman diagrams.

Secondary

Measure	Time frame	Description
Comparison of reproducibility of retinal sensitivity measurements assessed with microperimetry and conventional perimetry	Two measurement within one week	In addition to microperimetry conventional perimetry will be performed and reproducibility of both devices will be compared.
