Visual 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...
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...
متن کاملRelationship between optical coherence tomography, pattern electroretinogram and automated perimetry in eyes with temporal hemianopia from chiasmal compression.
PURPOSE To evaluate the relationship between pattern electroretinogram (PERG) amplitude, macular and retinal nerve fiber layer (RNFL) thickness by optical coherence tomography (OCT), and visual field (VF) loss on standard automated perimetry (SAP) in eyes with temporal hemianopia from chiasmal compression. METHODS Forty-one eyes from 41 patients with permanent temporal VF defects from chiasma...
متن کاملPrognostic value of the electroretinogram in severe recent ocular trauma.
In patients suffering from severe recent ocular trauma it is important to know the extent of the retinal damage before assessing the possible recovery of visual function. Ophthalmoscopic examination of the fundus is often impossible because of opacities of the ocular media caused by the trauma. In such cases the electroretinogram (ERG) is of value in assessing the state of the retina, but very ...
متن کاملthe role of visual aids and translation in teaching vocabulary in est
the present study investigated the effect of the two vocabulary teaching techniques in est, namely the use of translation and the use of visual aids as two separate vocabulary teaching techniques. to answer the question of the study, a pretest (michigan test) was administered to the 58 randomly selected est students at khajeh nasiredin tusi university, faculty of mechanics. after the homogeneit...
