Abstract
Introduction
Bitemporal hemianopia is usually caused by chiasmal pathology. Rarely, chorioretinal lesions may develop symmetrically in both eyes and mimic chiasmopathy.
Methods
This case series included three patients who presented to a tertiary neuro-ophthalmology centre with bitemporal hemianopic defects between 2021 and 2023 and were subsequently diagnosed with bilateral chorioretinopathy. All patients received comprehensive examinations from a fellowship-trained neuro-ophthalmologist and uveitis specialist to rule out other causes of visual dysfunction.
Results
Three males aged 64, 62, and 72 years were included. All patients showed bitemporal hemianopic defects crossing the vertical midline on automated perimetry and binasal thinning of the macular ganglion cell complex on spectral-domain optical coherence tomography (OCT). Fundus autofluorescence (FAF) showed classical features of acute zonal occult outer retinopathy (AZOOR) in two patients and central serous chorioretinopathy (CSCR) in another. AZOOR diagnosis was preceded by neuroimaging in both cases, whereas the patient with CSCR had longstanding, electroretinography-confirmed lesions and did not require neuroimaging. Fundus appearance and visual field defects remained stable in all patients across 3–6 months of follow-up.
Conclusions
Bilateral chorioretinopathy should be considered in the differential diagnosis of bitemporal hemianopia in specific cases, including when visual field defects cross the vertical midline and when neuroimaging fails to reveal chiasmal pathology. FAF and macular OCT have high diagnostic yield as initial investigations.
期刊介绍:
The Journal of the Neurological Sciences provides a medium for the prompt publication of original articles in neurology and neuroscience from around the world. JNS places special emphasis on articles that: 1) provide guidance to clinicians around the world (Best Practices, Global Neurology); 2) report cutting-edge science related to neurology (Basic and Translational Sciences); 3) educate readers about relevant and practical clinical outcomes in neurology (Outcomes Research); and 4) summarize or editorialize the current state of the literature (Reviews, Commentaries, and Editorials).
JNS accepts most types of manuscripts for consideration including original research papers, short communications, reviews, book reviews, letters to the Editor, opinions and editorials. Topics considered will be from neurology-related fields that are of interest to practicing physicians around the world. Examples include neuromuscular diseases, demyelination, atrophies, dementia, neoplasms, infections, epilepsies, disturbances of consciousness, stroke and cerebral circulation, growth and development, plasticity and intermediary metabolism.
