  patients with type 1 demonstrated some degree of

  diabetic retinopathy

• After 20 years of diabetes mellitus, nearly 99% of

  patients with type 2 demonstrated some degree of

  diabetic retinopathy

• Proliferative diabetic retinopathy was found in 50% of type 1

abnormality:

• Intraretinal microvascular abnormality

• capillary leakage (macular edema)

• sequelae from ischemia-induced neovascularization

Which of the following treatment criteria for clinically significant macular edema according to ETDRS ?

• retinal thickening located outside 500 μm of the center of the macula

• hard exudates at or within 500 μm of the center without thickening of adjacent retina

• hard exudates outside 500 μm of the center if associated with thickening of adjacent retina

• a zone of thickening larger than 1 disc area if located within 1 disc diameter of the center of the macula

Female 52 years old with type 2 DM came to eye clinic for diabetic retinopathy screening. Her VA was 6/9 in both eyes. Funduscopy examination of her right eye revealed intraretinal haemorrhages in two quadrants and some hard exudates. Funduscopy examination of her left eye revealed intraretinal haemorrhages in three quadrants, some hard exudates, and venous beading in 1 quadrant. When is the suggested follow up time for this patient?

• 6 months

• 3 months

• 2 months

• 1 month
