  1. BCVA best-corrected visual acuity, EDTRS Early Treatment Diabetic Retinopathy Study, EQ-5D EuroQoL five dimensions questionnaire, IEC, Independent Ethics Committee, IOP intraocular pressure, NEI-VFQ-25 National Eye Institute Visual Function questionnaire 25, RAPD relative afferent pupillary defect, SD-OCT spectral domain optical coherence tomography
  2. aPregnancy tests may also be repeated as per request of IECs or if required by local regulations. Only applicable for women of childbearing potential
  3. bOptional at all other visits: only if neovascularisation is suspected in slit lamp examination, gonioscopy or indirect ophthalmoscopy
  4. cIOP measurement by Goldmann applanation tonometry can be performed at any time of the day at the screening visit, V9 and at an unscheduled visit. The time (±1 h) of IOP measurement at the baseline visit is mandatory for all other visits (V3–V8)
  5. dPerimetry can be skipped if eligibility is fulfilled by other criteria
