Visual field defectThe aim of this study was to describe the ocular findings of an 8-year-old girl with bilateral superior segmental optic nerve hypoplasia (SSONH) whose mother had a history of Type 1 diabetes mellitus and to review the prior literature concerning this association. Neuro...
This is the first case report of a superior segmental optic hypoplasia (SSOH) combined with normal-tension glaucoma accompanied by a progressive glaucomatous visual field defect. A 40-year-old man, incidentally diagnosed as having bilateral SSOH, had disc hemorrhage associated with expansion of the...
DB, the first blindsight case to be tested extensively (Weiskrantz, 1986) has demonstrated the ability to detect and discriminate a range of visual stimuli presented within his perimetrically blind visual field defect. In a temporal two alternative forced choice (2AFC) detection experiment we have...
In patients, posterior lesions involving the homolog of MST produce a deficit in tracking similar to that in monkey, with impairment of ipsilateral pursuit, and a defect of motion processing affecting the contralateral visual hemifield (Thurston et al., 1988; Morrow and Sharpe, 1993; Barton et ...
In patients with damage to the primary visual cortex (V1), residual vision can guide goal-directed movements to targets in the blind field without awareness. This phenomenon has been termed blindsight, and its neural mechanisms are controversial. There s
Peripapillary and Macular Vessel Density in Patients with Glaucoma and Single-Hemifield Visual Field Defect. To compare hemifield differences in the vessel density of the peripapillary and macula in open-angle glaucoma eyes with visual field (VF) defect confined t... A Yarmohammadi,LM Zangwill,A ...
Sub-wavelength antireflection moth-eye structures were fabricated with Nickel mold using Roll-to-Plate (R2P) ultraviolet nanoimprint lithography (UV-NIL) on transparent polycarbonate (PC) substrates. Samples with well replicated patterns established an a
The Superior Mesenteric Vein is a blood vessel that is more tolerant to ligation compared to other veins, such as the SMV, and can be safely ligated when necessary. AI generated definition based on:Vascular Medicine: A Companion to Braunwald's Heart Disease (Second Edition),2013 ...
The rat femoral epicondylar defect was used for investigation as previously described [13]. Briefly, 300–350 g SD rats achieved general anesthesia with an intraperitoneal injection of 4% pentobarbital sodium (40 mg/kg body weight). A sterile field was created before local administration of 1% ...
The patients with SSOH usually have relatively good visual acuities with specific visual field changes of inferior altitudinal or sector defect connecting to the blind spot, and often are misdiagnosed as glaucomatous optic neuropathy (GON). GON, a progressive disease of the optic nerve head and ...
