Effect of Hemodialysis on Retinal Thickness in Patients with Diabetic Retinopathy, with and without Macular Edema, Using Optical Coherence Tomography

Table 4

Difference between retinal thicknesses in different parts of the eye before and after hemodialysis in diabetic retinopathy patients with (Group A) and without (Group B) macular edema.

Parameter	Group A	Group B	value
Difference of retinal thickness in the foveal area	−8.39 ± 38.69	1.75 ± 10.95	0.354
Difference of retinal thickness in the perifoveal area	−7.21 ± 25.42	−1.68 ± 16.11	0.497
Difference of retinal thickness in the peripheral macular area	2.21 ± 10.45	−3.29 ± 21.21	0.392
