Total quality Insulin resistance is not being treated Roy Taylor in Newcastle has shown an 90% reduction in blindness DT1 …70% screening…we need to improve our screening…good, but needs to be better I estimate can reduce blindness rate by 90% from current levels…organisation, without much extra expenditure Also know that basal bolus insulin reduces retinopathy to ~33% Laser pre-proliferative..controversial …lighter laser much earlier, + good control Intravitreal Triamcinolone…
Intravitreal Triamcinolone For diffuse macular oedema (laser is not effective) temporary Increases eye pressure …small % very high, rarely infection
Rapid control in type 2 (or type 1) Danger time…transfering to insulin Suggesting gradual improvement in control (really important never to let control get poor in the first pace) Do all diabetes practice nurses know this?
