ABSTRACT Normal-tension glaucoma (NTG) is a glaucomatous optic neuropathy that occurs in the absence of intraocular hypertension, and its pathophysiology is not solely dependent on pressure-related factors. Extrinsic mechanisms, such as autonomic dysfunction and microvascular hemodynamic alterations, have been implicated in its progression, with obstructive sleep apnea (OSA) standing out as an important contributing factor. We report the case of a patient with NTG and severe OSA confirmed by polysomnography, who exhibited progressive structural and functional loss despite controlled intraocular […]

ABSTRACT We present a case of an autosomal dominant optic neuropathy, known as Kjer’s disease. The condition can manifest since childhood, presenting with bilateral symmetric optic atrophy and progressive vision loss. Genetics play a crucial role in the differential diagnosis, due to the association with the OPA-1 gene. In this report, we describe the case of a young vegan woman, initially diagnosed with optic neuropathy due to nutritional deficiency, but with laboratory tests within normal limits and a significant family […]

ABSTRACT Objective: This systematic review aimed to investigate the prevalence and incidence of optic neuropathy in older adults. Methods: A search was conducted in the following databases: Medline/Pubmed, Embase, Scielo, and BVS, and data extraction for this review encompassed the period up until March 2023, using MeSH terms and Boolean operators. The selected search strategy and methods were registered in the PROSPERO database (#CRD42023403901). Results: Twelve articles were included for analysis, comprising four case-control studies and seven cohort studies. The […]

ABSTRACT Although coloboma of optic nerve head and/or chorioretinal tissue is not uncommon, duplication or pseudoduplication of the optic disc is rare. Here we report a rare case of pseudotripling of optic disc in a 50-year-old asymptomatic male patient. Orbital magnetic resonance image confirmed presence of only one optic nerve.

Objectives: To correlate ophthalmoscopic and cardiovascular parameters in patients diagnosed with low-output heart failure (HFrEF) and to evaluate the association between HFrEF and glaucoma-suggestive alterations in the optic nerve. Methods: Descriptive, observational and prospective study, composed of 30 patients diagnosed with HFrEF. The patients were submitted to ophthalmologic examination, which included biomicroscopy, visual acuity, gonioscopy, intraocular pressure (IOP) and central corneal thickness (CCT) measurement. Their cardiovascular parameters evaluation, such as mean arterial pressure (MAP), left ventricular ejection fraction (LVEF), comorbidities […]

The purpose of this research is to describe a clinical study of a male patient who experienced late-blindness due to traumatic optic neuropathy after getting into a bicycle accident. It is stressed the importance of performing pupillary/reflexes examination and computed tomography scan in order to diagnose “transorbitário” foreign body. It is also cover its surgical removal as well as an interdisciplinary approach and clinical evolution.

O glaucoma compreende um grupo de neuropatias ópticas progressivas que tem em comum a degeneração lenta e progressiva das células ganglionares e seus axônios, resultando em aparência única do disco óptico e, simultaneamente, um padrão correspondente de perda visual. Biomarcadores são características medidas objetivamente e avaliadas como indicadores de processo biológico normal, processos patológicos ou respostas farmacológicas à uma intervenção terapêutica. Vários marcadores biológicos foram associados com glaucoma, especialmente os genéticos, proteômicos, autoimunes e outros biomarcadores moleculares, embora a maioria […]

Dolichoectasia of the internal carotid artery (ICA) is a rare condition that may be associated with neuro-ophthalmic manifestations, such as loss of visual acuity and visual field resulting from compression of the optic nerve (ON). The aim is to report a 67-year-old male patient with primary open-angle glaucoma (POAG) with atypical evolution, asymmetry of cupping and increased pallor of the rim of the left ON, due to compressive optic neuropathy by the dolichoectatic segment. The diagnosis was based on clinical […]
