Changes of Retinal Nerve Fiber Layer Thickness Around Optic Disc and Macular Retinal Thick-ness in Patients with Type 2 Diabetes Mellitus Observed by Optical Coherence Tomography
Abstract:To observe the changes of retinal nerve fiber layer (RNFL ) thickness around optic disc and macular retinal thickness in patients with type 2 diabetes mellitus (T2DM ) by optical coherence tomography (OCT) .[Methods]OCT was used to measure the changes of RNFL thickness around optic disc and macular retinal thickness in normal control group ,non-diabetic retinopathy (NDR) group and non-proliferative diabetic retinopathy (NPDR) group .[Results]RNFL thickness beside optic papilla in NDR group was thinner than that in control group , but that in NPDR group was thicker than that in control group .Macular retinal thickness in NDR group was thinner than that in control group ,but that in NPDR group was thicker than that in control group .[Conclusion] OCT can quantitatively observe the changes of RNFL thickness around optic disc and macular retinal thickness ,and is a reliable method for the diagnosis and treatment of diabetic retinopathy .
