Diabetic Eye Disease Flashcards
Diabetic Retinopathy (DR)
Can be non-?(NPDR) or ?(PDR).
PDR is more common in type ? diabetes.
Risk factors are poor ?, ?, ? and ?.
proliferative 2 control HTN smoking pregnancy
NPDR;
Usually ?, and always occurs at some severity after ?-?y of DM.
Features on fundoscopy;
o Micro-?.
o ?: due to leaky vasculature.
o Haemorrhages: ?, ?, ? shaped.
o ? ? spots (>? indicates ‘pre-proliferative’ retinopathy).
Can progress into ? diabetic retinopathy.
Management is with good ? ?.

PDR;
Characterised by the development of ? ?on the optic ? or ? as a response to significant retinal ?.
o ? leads to vascular endothelial growth factor (VEGF) ?.
The vessels are ?, and likely to ? with the traction that occurs when they are growing forward to give a pre-? or ? haemorrhage.
o Manifests as a sudden ? in ?.

PDR
If untreated, the blood vessels will cause ? and a tractional retinal ?, again leading to loss of ?.
They can also cause ? ? ? glaucoma due to ? neovascularization, known as rubeosis iridis.

PDR
Management;
PDR is treated with pan-? ?.
o Aim is to reduce the ? drive and ?production.
? can be used to remove persistent ?haemorrhage

Diabetic Maculopathy;
Diabetic maculopathy is more common in type ? diabetes.
o Specific type of retinopathy that affects the macula.
o Typically presents as ? of the vision.
There are three subtypes; ?, ? and ?. .
Management is with focal ? to stop focal ?, but ? maculopathies require more complex treatments.

Cataract formation.
Increased rates of ?-related cataracts in diabetics.
o ? sub-? cataracts are the most common.
Symptoms are trouble with ? sunlight/ headlights and ? vision .

Glaucoma.
Increased incidence of ? ? angle glaucoma in diabetics.
This is ? until the patient has extremely restricted visual ?.
