Homonymous hemianopsia caused by chiasmal compression due to intracranial aneurysm.
Two cases of homonymous hemianopsia caused by chiasmal compression due to in tracranial aneurysm are presented. Both cases are aneurysms of the internal carotid artery and these aneurysms developed to the median direction. Visual field defects in both cases were incongruous homonymous hemianopsia without macular sparing. It should be noted that when homonymous hemianopsia is present without any...
متن کاملVisual prognostic value of the pattern electroretinogram in chiasmal compression.
BACKGROUND/AIMS The visual loss associated with compression of the optic chiasm by pituitary tumours may be transient or permanent, possibly related to the extent of irreversible retrograde degeneration to the retinal ganglion cells. The pattern electroretinogram (PERG) N95 component is thought to rise in relation to retinal ganglion cell function and hence may be a potential prognostic indicat...

2 were 2.23 (95% confidence interval, 1.34-3.70) times as likely to be aware of EBPs as those in group 1 in treating HSV stromal keratitis. Clinicians in group 3 were 2.92 (95% confidence interval, 1.70-5.01) and 2.27 (95% confidence interval, 1.29-3.98) times as likely to be aware of EBPs as their group 1 counterparts in treating HSV stromal keratitis and preventing recurrent HSV stromal kerat...
متن کاملMacular Ganglion Cell Analysis Determined by Cirrus HD Optical Coherence Tomography for Early Detecting Chiasmal Compression.
PURPOSE To evaluate the performance of macular ganglion cell-inner plexiform layer (mGCIPL) measurement with Cirrus high-definition (HD) optical coherence tomography (OCT) for early detection of optic chiasmal compression. METHODS Forty-six eyes of 46 patients with optic chiasmal compression caused by a pituitary adenoma (PA group), 31 eyes of 31 patients with normal tension glaucoma (NTG gro...
متن کاملVisual prognostic value of optical coherence tomography and photopic negative response in chiasmal compression.
PURPOSE To investigate the potential of the optical coherence tomography (OCT) measurement of retinal nerve fiber layer (RNFL) thickness and ganglion cell complex (GCC) area and photopic negative response (PhNR) for predicting postoperative visual outcome in chiasmal compression, prospectively. METHODS Eighteen eyes of 18 patients undergoing chiasmal decompression surgery were prospectively a...
