- - - - Bloods
        FBC, U+E, LFTs, clotting,
        glucose (DM), lipids
        Immune screen (ANCA, ANA)
      - Bedside
        Obs (HTN, fever if vasculitis)
      - Imaging
        Fundus fluorescein angiogram (degree of ischemia)
  - - - Panretinal photocoagulation
        Indication: ASAP for CRVO
        MOA: stops bleeding vessels
      - Intravitreal anti-VEGF
        Indication: macular oedema
        E.g. bevacizumab, ranibizumab
        MOA: reduces inflammation in the retina
      - Intravitreal steroids
        Indication: macular oedema
        MOA: implant, reduces inflammation
- - - - Aqueous drainage
        Indication: ASAP if <12h start
        MOA: drain aqueous to aid vessel perfusion
    - - CA inhibitor
        Indication: ASAP if <8-12h
        E.g. IV acetazolamide
        MOA: inhibits aqueous production,
        reducing IOP and aiding drainage of vessels
      - Aspirin
        Indication: all patients
        MOA: antiplatelet, reduces risk further clots
