Investigating the frequency characteristics of the electroretinogram signal in patients with central retinal vein occlusion
Background: Central retinal vein occlusion (CRVO) is the second most common retinal vascular disorder after diabetic retinopathy. In this study, we tried to examine the potentials of time-frequency methods for differentiating the eyes with CRVO. Materials and methods: Twenty patients with unilateral CRVO were included in this study. Their contralateral normal eyes were considered as the control...
متن کاملMultifocal electroretinographic features of central retinal vein occlusion.
PURPOSE To determine the features of wide-field multifocal electroretinography (WF-mfERG) recorded in patients with central retinal vein occlusion (CRVO) and to compare WF-mfERG responses of the affected and fellow eyes. In addition, WF-mfERG responses were also compared by using standard electroretinography (ERG). METHODS WF-mfERG and ERG responses were recorded from both eyes of 56 patients...
متن کاملSulfur Mustard Exposure and Non-Ischemic Central Retinal Vein Occlusion
A 41-year-old man was referred with a complaint of visual loss in his left eye and his best corrected visual acuity was 20/80. Slit lamp examination showed arborizing conjunctival vessels and dry eye. Fundus examination and fluorescein angiography revealed a non-ischemic central retinal vein occlusion. Cardiovascular, rheumatologic, and hematologic work up showed no abnormal findings. An ascert...
متن کاملBranch Retinal Vein Occlusion followed by Central Retinal Vein Occlusion
A 59-year-old woman with history of noninsulin dependent diabetes mellitus and systemic hypertension presented with decreased vision in her left eye since 2 months ago. Bestcorrected visual acuity (BCVA) was 20/20 and 20/400 in the right and left eyes respectively. Relative afferent pupillary defect was negative. Anterior segment examination was unremarkable except for mild posterior subcapsula...
متن کاملmultifocal electroretinography in the assessment of eyes with central retinal vein occlusion
data suggest that the multifocal electroretinography (mferg) may have a role in the assessment of patients with central retinal vein occlusion (crvo). to explore the mferg responses in patients with crvo. mferg responses were recorded at 61 discrete retinal locations from both eyes of 25 patients diagnosed with retinal vein occlusions within 3 weeks of onset. the latencies and amplitudes of ave...
