“…Occlusion of the PCA commonly produces macula-sparing hemianopsia and rarely causes HMV, since it likely damages the anterior part of the calcarine cortex and spares the tip of the occipital lobe [5][6][7][8][9]. This view has been widely accepted in the field of neuro-ophthalmology for years [3,4].…”

“…According to textbooks of neuro-ophthalmology, ischemic stroke rarely causes HMV [3,4]. The manifestation of HMV in stroke has been reported by several authors as a case report [5][6][7][8][9], but has never been studied systematically in a group of patients. We retrospectively studied the results of Goldmann's visual field tests in patients with infarction of the posterior cerebral artery (PCA) territory to elucidate the incidence of HMV and the location of lesions producing this visual manifestation.…”

It is generally believed that a homonymous defect of macular vision (HMV) is caused by a small lesion restricted to the occipital lobe tip and rarely results from ischemic stroke. The incidence of HMV was studied retrospectively in 54 patients with infarction of the posterior cerebral artery territory who underwent Goldmann’s visual field test. HMV was found in 6 patients (11%). In all of them, HMV was first dismissed due to a confrontation test of visual fields at the bedside and later detected by Goldmann’s visual field test. All had a relatively large infarction extending from the occipital lobe tip to the posterior part of the calcarine cortex and/or the neighboring subcortical regions. Stroke-induced HMV can be caused by a large lesion involving the occipital pole and may not be so rare as generally considered.

Bilateral central scotoma with preservation of central vision in 2 patients following caesarian section under spinal anesthesia

1987

View full text Add to dashboard Cite

Two female patients are described with acute bilateral central scotomata with preservation of central vision following spinal anesthesia. Both patients had a temporary drop in systemic blood pressure and underwent caesarean section with moderate blood loss. In order to explain the visual field defects extensive ophthalmological examination and CT-scanning with nuclear magnetic resonance imaging were performed. The hypothetical explanation for the visual field defects is transient macular ischemia.

“…In other previous cases of bilateral homonymous hemianopia, various degrees of macular sparing 6,7,[20][21][22][23] or quadrant sparing, 23 which could be asymmetrical, have been described. This is the first report of complete unilateral sparing of the vertical meridian in a case of bilateral homonymous hemianopia.…”
