Purpose:
|
To evaluate visual function in patients with NPDR, diabetics with no diabetic retinopathy (NDR) and compare with normals.
|
|
Methods:
|
In a cross sectional study, patients with type II (DM2) were assigned as case group (including NDR, mild NPDR and moderate-severe NPDR) and normals were included as controls. All cases and controls had BCVA of 20/20, having same stages of diabetic retinopathy in both eyes and absence of any other ocular pathologic condition except DR. All cases and controls were evaluated for color vision, stereopsis, photostress recovery time, color comparison, brightness comparison and contrast sensitivity with and without glare.

|
Results:
|
A total of 92 participants, with a matched age and sex distribution (case and control 46.16±8.46 and 41.64±10.10 years and 40.7% and 44.0%male respectively) 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), area under log contrast sensitivity (log CS) function (AULCSF) with(r=-0.395,P=0.001) and without (r=-0.435,P<0.001) glare and stage of DR. This study also demonstrated a significant difference between control and NDR group in mean of stereopsis (P<0.001), brightness comparison (P=0.022), AULCSFs without (P=0.026) glare.

|
Conclusion:
|
This study showed more severe stage of DR, more decrement in visual function, even in NDR with normal VA.
