  1. Decreased vessel density is associated with impaired visual sensitivity in the early stage of normal-tension glaucoma.
  2. Patterns of retinal vasculature changes differ between normal-tension glaucoma and primary angle-closure glaucoma.
  3. Lower retinal vasculature density at baseline is associated with faster progression of normal-tension glaucoma.
  4. Vascular changes develop prior to retinal nerve fibre layer (RNFL) thinning in normal-tension glaucoma, whereas RNFL thinning develops prior to vascular changes in primary angle-closure glaucoma.
