Inclusion criteria

* Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the study * Age \>=60 years * Ability (including a sufficient general health status according to investigators judgement) and willingness to undertake all scheduled visits and assessments including predefined methodology and standards utilizing microperimetry GA secondary to AMD with no evidence of prior or active choroidal neovascularization (CNV) in the study eye * GA lesion in the study eye must reside completely within the FAF imaging field (Field 2- 30 degree image centered on the fovea) * BCVA of 20/63 or better (Snellen equivalent) using ETDRS charts at starting distance of 4 m in the study eye * Well demarcated area(s) of GA secondary to AMD with no evidence of prior or active CNV in the study eye * The total GA lesion size \>=1.2 mm\^2 (approximately \>=0.5 disc area \[DA\]) and \<=17.78 mm\^2 (approximately \<=7 DA) and must reside completely within the FAF imaging field (Field 2-30 degree image centered on the fovea) * If GA is multifocal, at least 1 focal lesion must be \>=1.2 mm\^2 (approximately \>=0.5 DA) * Sufficiently clear ocular media, adequate pupillary dilation, and fixation to permit quality fundus imaging in the study eye

Exclusion criteria

* GA in either eye due to causes other than AMD (for example, monogenetic macular dystrophies \[e.g., Stargardt disease, cone rod dystrophy\] or toxic maculopathies \[e.g., chloroquine/hydroxychloroquine maculopathy\]) * Receiving active treatment in any studies of investigational drugs for GA/dry AMD in the study eye * Mean sensitivity difference \> 3 dB between the two microperimetry examinations in the screening visit. * History of vitrectomy surgery, submacular surgery, or other surgical intervention for AMD in the study eye * Previous laser photocoagulation for CNV, diabetic macular edema, retinal vein occlusion, and proliferative diabetic retinopathy in the study eye * Prior treatment with Visudyne ®, external-beam radiation therapy, or transpupillary thermotherapy in the study eye * History of prophylactic subthreshold laser treatment for AMD in the study eye * Further criteria apply.

Recruitment details

A biomarker evaluation study in patients with geographic atrophy secondary to age-related macular degeneration (AMD) evaluating the use of microperimetry (fundus-controlled perimetry) and Swept Source-Optical Coherence Tomography in assessing changes in retinal sensitivity and anatomy over observation period of 48 weeks.

Pre-assignment details

All subjects were screened for eligibility prior to participation in the trial. Subjects attended a specialist site which ensured that they (the subjects) strictly met all inclusion and none of the exclusion criteria. Subjects were not to be allocated to a treatment group if any of the entry criteria were violated.

Participants by arm

ArmCount
All Enrolled
All enrolled participants who had geographic atrophy secondary to age-related macular degeneration, signed informed consent for this trial, and met all inclusion criteria and none of the exclusion criteria, for evaluating the usage of microperimetry and Swept Source - Optical Coherence Tomography (SS-OCT) in assessing the natural changes of retinal sensitivity and anatomy in the retina. Each participant was planned to be observed for an observation period of 48 weeks after screening visit. During the observation period, 4 visits were planned to be taken at Week 0, 12, 24, and 48 of the observation period.
