  • Active neovascular AMD in the study eye
  • Intravitreal dose of 0.5 mg ranibizumab or 2 mg aflibercept required, as per current clinical guidelines
  • Venous access that is sufficient to allow easy blood sampling on a frequent basis
  • Able to give written consent
  • Willingness to comply with all study procedures
  • Are the trial subjects under 18? no
  • Number of subjects for this age range: 0
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range 62
  • F.1.3 Elderly (>=65 years) yes

排除标准

  • Myopia greater than 8 dioptres in the study eye
  • Axial length of eye under 20mm or over 26mm
  • Aphakia in study eye
  • Pseudophakia with a defect in the posterior capsule
  • Glaucoma in study eye
  • Current renal dialysis
  • Presence of inflammatory eye conditions, such as uveitis, or systemic conditions likely to elevate CRP.
  • Intraocular surgery within 6 months of enrolment, except for routine phacoemulsification cataract surgery that may occur within 4 months of enrolment
  • Current treatment for wet age-related macular degeneration with an intravitreal agent other than ranibizumab or aflibercept in the study eye. Patients expected to change their anti-VEGF agent during the sampling period are also excluded.
  • Known significant allergy to ranibizumab or aflibercept
  • Participants who, in the opinion of the Investigator, would not be willing or able to comply with the study protocol or provide informed consent.
  • Patients with severe anaemia
  • Patients who have received anti-VEGF therapy in either eye within 8 weeks of enrolment, or who are likely to require anti-VEGF treatment in the fellow eye during the course of venous sampling. Note that the final venous sample at 4 weeks can be undertaken on the same day as an anti-VEGF injection, but must be taken prior to any injection.
  • Patients presently taking any topical (skin or eye), periocular, intraocular, local or systemic treatment with immunosuppressive or anti-inflammatory agents, such as steroids, steroid sparing agents, and NSAIDs. Patients who have received any of these agents within 2 months prior to enrolment are also excluded, as are those thought likely to receive these medications during the course of venous sampling.
