TitleNonglaucomatous optic nerve atrophy
PurposeTo determine the frequency and clinical characteristics of nonglaucomatous optic nerve atrophy in Congolese patients.
MethodsA cross-sectional study performed between January 2005 and August 2016 at a general practice of ophthalmology in Kinshasa. All patients with the diagnosis of nonglaucomatous optic nerve atrophy examined during the study period were included in the study. All the patients had an interview and a physical examination, including a detailed neurologic examination, a comprehensive ophthalmologic examination, which included inspection of adnexa, visual acuity measurement, pupillary reaction, biomicroscopy, funduscopy and measurement of the intraocular pressure, visual field evaluation . In some cases, computed tomographic scanning or magnetic resonance scanning were necessary (to rule out a compressive optic neuropathy). The diagnosis of nonglaucomatous optic nerve atrophy was based not only on changes in the appearance of the optic nerve head but also specifically on alterations in its function.
ResultsOut of 17469 patients seen during the study period, 132 patients were diagnosed with nonglaucomatous optic atrophy, for a frequency of 0.76%. There were 76 males and 56 females with a male:female of 1.3:1. Their ages ranged from 1 to 89 years with a mean age of 5019 years. The etiology was unknown in 55%. Nonglaucomatous optic atrophy was associated with, in most cases, chorioretinal disease, trauma, toxic lesion, vascular disease and tumor lesions.
ConclusionA thoroughly investigation is needed to make diagnostic etiology of a nonglaucomatous optic atrophy.
