Ischemic Optic Neuropathies

The Prevalence of diabetic optic neuropathy in type 2 diabetes mellitus

“…A history of poor metabolic control present in 50% of patients. 1 In our patients the poor metabolic control represents 63(71%) patients which are comparable to this finding.…”

“…1 It is noticed in our patients that diabetic optic neuropathy not related to the severity of diabetic retinopathy as we have 50% of cases not associated with significant diabetic retinopathy, Also it is noticed in one study that optic disk edema does not correlate with the degree of diabetic retinopathy. 12 More reports that are recent suggest that older patients and patients with type 2 diabetes may actually comprise the majority of cases.…”

“…Diabetic papillopathy may also be seen in patients with adult-onset diabetes mellitus. 1 Acute optic disc edema associated with diabetes, or diabetic papillopathy, usually occurs in the second to fourth decades of life and generally shows no correlation with the severity of diabetic retinopathy. It is typically associated with mild loss of vision (≥20/50) and the visual field may be normal or may show defects, such as an increased blind spot, arcuate scotomas, or altitudinal scotomas.…”

“…optic nerve diseases: Diabetic papillopathy depends on clinical examination visual acuity which is mildly affected with Fundoscopy that shows variable disc hyperemia and pallor. 1 Non-arteritic anterior ischemic optic neuropathy (NAION) is characterized by the following triad: abrupt (usually monocular), painless loss of vision; optic disc swelling with or without surface hemorrhages and cotton-wool spots; and nerve fiber bundle defects in the visual field of the affected eye. 4 Primary open angle glaucoma (POAG) also known as chronic simple glaucoma of adult onset and is typically characterized by slowly progressive raised intraocular pressure (>21 mmHg recorded on at least a few occasions) associated with characteristic optic disc cupping and specific visual field defects.…”
