- Status
- COMPLETED
- Sex
- All
- Target Recruitment
- 255
Inclusion criteria for patients:
- Aged 60 years or over at the time of GA diagnosis
- Patients providing informed consent to participate in the study; if the patient is physically incapable of completing the electronic consent form, the form can be completed by a legally acceptable representative of the patient (including an impartial witness, where required)
- Patients first diagnosed with GA in at least 1 eye between 3 and 10 years prior to index date
- For patients with unilateral GA, the other eye should show signs of AMD (i.e., the non-GA eye should present with at least drusen, reticular pseudodrusen, or wet-AMD)
Inclusion criteria for caregivers:
- Aged 18 years or over at the time of consent
- Caregivers who self-identify as the primary caregiver for a patient for whom documented informed consent for inclusion in the study has been obtained
Exclusion criteria for patients:
- Patients diagnosed with GA due to causes other than AMD (e.g., monogenetic macular dystrophies [Stargardt disease, other], toxic maculopathies) in either eye
- GA with any concurrent intraocular condition that in the opinion of the treating physician would require surgical or intravitreal intervention (for the prevention or treatment of visual loss) during the study or might impact the interpretation of routine clinical assessments e.g., glaucoma, cataract, proliferative diabetic retinopathy. Patients first diagnosed with GA less than 3 years prior to the date of consent
- Patients who have not attended a healthcare institution for the management of GA following diagnosis of GA (a minimum of 2 routine clinical visits for monitoring of GA that included assessment of at least BCVA should be documented in the medical records)
- Patients who have been enrolled in an interventional clinical trial in which they received medication for any retinal condition (note: patients with bilateral GA should be excluded only if both eyes received the pharmacological intervention)
Exclusion criteria for caregivers:
- Caregivers for whom documented informed consent has not been obtained for participation in the GALTOS survey
- Caregivers with any significant mental incapacity that would prevent them from participating in the survey
- Paid caregivers

Mean change in functional parameters in patients with microperimetry assessments Through study completion; between 4 and 11 years Mean/Median and Mean change in number of scotoma points.
- Secondary Outcome Measures
Name Time Method Proportion of GA eyes with presence of selected characteristics Through study completion; between 4 and 11 years Proportion of GA eyes with presence of any of the following: nAMD, drusen, pseudodrusen, foveal involvement, unifocal/multifocal GA, hypopigmentation
Proportion of non-GA eyes with presence of AMD Through study completion; between 4 and 11 years Proportion of non-GA eyes with presence of any of the following: early/intermediate AMD, nAMD, MNV
Mortality rate From enrollment until end of follow-up; 12 (+6) months after the follow-up period. Mortality rate during study follow-up
GA-related HCRU during the observation period Through study completion; between 4 and 11 years number of prescribed vision aids, per participant
Financial impact of GA on patients and caregivers From enrollment until end of follow-up; 12 (+6) months after the follow-up period. Selected items of the GALTOS survey (including the cost, in the past 12 months, associated to prescriptions, assistive devices, healthcare-related travel, etc.)
Associations between patient characteristics and disease progression/functional outcomes and/or clinical/anatomical/functional outcome measures Through study completion; between 4 and 11 years Measures of association such as correlation coefficients, chi-square statistic, and potentially coefficients from multivariate analysis methods characterizing the relationships of interest
Patient-reported HRQoL From enrollment until end of follow-up; 12 (+6) months after the follow-up period. Score of the AQoL-7D for Australian sites only.
Patient-reported performance From enrollment until end of follow-up; 12 (+6) months after the follow-up period. Scores/answers to the GALTOS survey.
Assisted-care patient journey From enrollment until end of follow-up; 12 (+6) months after the follow-up period. mean/median time from GA diagnosis to first type of assistance
