Case 69 Teaching Points

  • Disease can exist as either a congenital form (mild form of Coats disease) or an acquired form seen most commonly in middle-aged patients
  • Six different classifications based upon location of abnormal vessels and other factors, such as presence of an exudative component. This case falls into group 2, bilateral acquired parafoveal telangiectasis, which is the most common group.
  • Most common location is temporal to the foveolar avascular zone, which may be a watershed area of retinal circulation
  • An association with diabetes has been suggested but needs to be studied further
  • Treatments are currently limited as photocoagulation has not been shown to be beneficial
