To evaluate visual function in patients with NPDR, diabetics with no DR (NDR) and compare with normal controls.
Eye Research Center, Farabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran
In a cross sectional study, patients with DM2 were assigned as cases (including NDR, mild NPDR and moderate-severe NPDR) and normal patients were included as controls. All the cases and controls had BCVA of 20/20, having same stages of DR in both eyes and absence of any other ocular pathologic condition except DR. All the cases and the controls were evaluated for the color vision, stereopsis, photostress recovery time, color comparison, brightness comparison, and contrast sensitivity with and without glare.
A total of 92 participants, with a matched age and sex distribution (case and control46.16±8.46 and 41.64±10.10 years and 40.7% and 44.0%malerespectively) were evaluated. A correlation was observed between color cap separation mistake(r=0.291,P=0.018), stereopsis(r=0.492,P<0.001), photostress recovery time (r=0.306,P=0.015), AULCSF with(r= -0.395,P=0.001) and without(r= -0.435,P<0.001) glare and the stage of diabetic retinopathy. This study also demonstrated a significant difference between the control and NDR group in the mean of stereopsis (P<0.001), brightness comparison (P=0.022), AULCSFs without glare (P=0.026).
This study showed the more severe the stage of DR, the more decrement in visual function, even in NDR with normal visual acuity.
