Pattern reversal visual evoked potentials in eyes with macular holes and their fellow eyes.
PURPOSE To investigate whether the pattern reversal visual evoked potential can be useful in the diagnosis and management of macular hole patients. METHODS The pattern reversal visual evoked potential was measured in 66 patients with a macular hole and in 43 healthy control subjects. Check sizes of 34', 17' and 10' were applied. RESULTS Results showed that, for the check sizes of 34', 17' a...
متن کامل4244 Alteration of pattern reversal visual evoked potentials in eyes with macular holes and their fellow eyes
The pattern VEP is frequently abnormal in multiple sclerosis. In this disease the VEP latency is prolonged and the amplitude is reduced. The use of the VEP amplitude in diagnosis is limited because of the large interand intrasubject variability and low signal-to-noise ratio (SNR). Goal of this project is to improve the SNR of VEP’s with alternative averaging procedures, and to investigate wheth...
متن کاملHyperautofluorescent ring in eyes with macular holes
BACKGROUND Fundus autofluorescence studies in eyes with macular holes (MHs) have shown a hyperautofluorescent spot corresponding to the hole and a hypoautofluorescent ring corresponding to the fluid cuff surrounding the hole. The purpose of this report is to present three cases of MH with a different fundus autofluorescence pattern. CASE REPORTS Case 1 was a 62-year-old woman who did not know...
متن کاملWider Retinal Artery Trajectories in Eyes with Macular Hole Than in Fellow Eyes of Patients with Unilateral Idiopathic Macular Hole
PURPOSE To determine whether the width of the retinal artery (RA) trajectory was associated with the presence of a macular hole (MH). METHODS A retrospective cross sectional case-control study was performed. The fundus photographs were rotated 90 degrees, and the coordinates of the best fit curve of the RA trajectory were determined automatically based on these plots using the ImageJ program....
متن کاملValue of hyperventilation in pattern-reversal visual evoked potentials.
The effects of a standard 3 minutes' hyperventilation on the full-field pattern-reversal visual evoked potential (VEP) were studied in 33 normal subjects, 30 definite multiple sclerosis patients and in twenty-five patients with abnormal VEPs due to either tumourous compression of the anterior visual pathways or optic atrophy of other origin. Significantly greater reductions in P100 latency occu...
