Bariatric procedures, associated with gastrointestinal malabsorption of vitamins and microelements, may constitute a risk factor for nutritional optic neuropathy (NON). We present a case of a 34-year-old female patient who developed bilateral NON after sleeve gastrectomy. Despite postoperative ophthalmological supervision, 10 months after the procedure the woman presented with a bilateral decre...

PURPOSE To report a case of bilateral ophthalmic artery occlusion in rhino-orbito-cerebral mucormycosis. METHODS Reviewed clinical charts, photographs, and fluorescein angiography RESULTS An 89-year-old man with poorly controlled diabetes developed sudden bilateral ptosis, complete ophthalmoplegia of the right eye, and superior rectus palsy of the left eye. Brain and orbit magnetic resonanc...

A 55-year-old woman was referred to our clinic because of a one-week history of visual loss and raised intraocular pressure in the left eye followed 4 days later by visual loss in the right eye. Slit-lamp examination showed bilateral conjunctival hyperemia, slight diffuse corneal edema, shallow anterior chamber and fixed and dilated pupil in both eyes. Splitting of the anterior layers of the ir...

Bilateral symmetry of disorders of vision is examined in 60 typical patients with retinitis pigmentosa. We observed a very high degree of interocular congruence in the patterns of both kinetic visual field defects and threshold profiles and in abnormalities of foveal colour discrimination and visual acuity. Abnormalities of foveal colour vision are highly correlated with the extent of visual ...

CONTEXT Leber's hereditary optic neuropathy is an important cause of progressive painless visual loss among young male patients. OBJECTIVE To report on a case of a young patient with a clinical and neurophysiological condition suggestive of Leber's hereditary optic neuropathy, confirmed by genetic testing. CASE REPORT We describe a 17-year-old male with progressive bilateral visual loss. Tw...

PURPOSE To determine the sources of binocular visual field loss most strongly associated with falls in a cohort of older women. METHODS In the Study of Osteoporotic Fractures, women with severe binocular visual field loss had an increased risk of two or more falls during the 12 months following the eye examination. The lens and fundus photographs of the 422 women with severe binocular visual ...

The electroretinogram (ERG) and the pattern visual evoked responses (VER) obtained from patients with suspected primary optic nerve lesions have been analysed. Patients with hereditary optic atrophy or optic nerve lesions with retinal disease or with systemic disorders were excluded from the analysis. According to the results of the ERG functions and VER, 83 patients with suspected primary opti...

INTRODUCTION Nutritional optic neuropathies are uncommon and can be associated with gradual visual loss and optic atrophy or sudden vision loss and optic disc swelling. CASE PRESENTATION A 44-year-old woman presented with a 4-week history of progressive visual loss and was noted to have bilateral retrobulbar optic neuropathy. No other clinical abnormality was noted. Investigations revealed se...

Leber inherited optic neuropathy (LHON) is characterized by subacute bilateral loss of central vision due to dysfunction and loss of retinal ganglion cells (RGCs). Comprehensive visual electrophysiological investigations (including pattern reversal visual evoked potentials, pattern electroretinography and the photopic negative response) performed on 13 patients with acute and chronic LHON indic...
