“…OTL is a relatively rare clinical entity, and previous publications present case series with various etiologies as summarized in Table 1 . Monteiro and Hokazone ( 22 ) described two cases in young patients, one due to trauma and the other a diagnosed tumor. Kanamori et al ( 23 ) reported trauma, arterio-venous malformation, and two cases of malignancy resulting in right homonymous hemianopia due to left OTL.…”

Optic tract lesions (OTL) are often difficult to diagnose. We suggest an algorithm to simplify the often-challenging diagnosis of OTL. Clinical and imaging data were retrospectively collected from the electronic files of 6 patients diagnosed with OTL at a tertiary medical center in 2016–2020. The series included 4 children and 2 adults with an OTL caused by a glioma (n = 5) or motor vehicle accident (n = 1). Magnetic resonance imaging (MRI) revealed a suprasellar glioma involving the chiasm and tract alone (n = 1) and the ipsilateral optic nerve (n = 2) and only optic tract (3). Perimetry showed incongruent homonymous hemianopia in 3 patients. In two patients, perimetry could only be performed in one eye, and demonstrated hemianopia. In one patient perimetry was unreliable. Fundus examination revealed bow-tie atrophy in all patients. On optical coherence tomography (OCT) of the peripapillary retinal nerve fiber layer (RNFL) horizontal thinning was observed in the contralateral eye (n = 6). By presenting the information in a predefined order—visual field damage, OCT RNFL thickness, and MRI—the diagnosis could be easily reached even in children, and when other structures like the chiasm were involved. Fundus photographs easily detect bow tie atrophy in children. Systematic presentation of the data in a predefined order can ease the diagnostic process of OTLs.

“…(86) No olho da hemianopsia nasal evidenciou-se a perda de fibras nos quadrantes superior e inferior do disco óptico, acometendo, portanto, as fibras da retina temporal que penetram o olho pelas arcadas superior e inferior. Os casos serviram para confirmar o valor da TCO na identificação da perda neural nestes pacientes.…”

Avaliação da camada de fibras nervosas da retina nas afecções neuroftalmológicas da via óptica anterior Retinal nerve fiber evaluation in neuro-ophthalmic diseases of the anterior visual pathwayMário Luiz Ribeiro Monteiro* RESUMOA avaliação da camada de fibras nervosas da retina tem grande importância no diagnóstico e acompanhamento de várias afecções da via óptica anterior. Nesta revisão, discutiremos os principais métodos de análise clínica e instrumental da camada de fibras nervosas da retina e revisamos os principais achados encontrados nas afecções da via óptica anterior incluindo lesões inflamatórias, isquêmicas, tóxicas, hereditárias, compressivas e traumáticas do nervo óptico, as lesões do quiasma óptico, as do trato óptico e aquelas do corpo geniculado lateral.Descritores: Camada de fibras nervosas da retina; Neuropatias ópticas; Quiasma; Trato óptico; Corpo geniculado lateral; Tomografia de coerência óptica ABSTRACTRetinal nerve fiber evaluation is important in the diagnosis and management of several diseases of the anterior visual pathway. In this report we review the clinical findings and the current techonologies avalilable to analyse the retinal nerve fiber layer. We furthermore review the main findings in several disease of the anterior visual pathways including inflammatory, ischemic, toxics, hereditary, compressive and traumatic optic neuropathies as well as lesion of the optic chiasm, optic tract and lateral geniculate body.
