The relationship between visual field size and electroretinogram amplitude in retinitis pigmentosa.
PURPOSE To determine to what degree visual field size is correlated with electroretinogram (ERG) amplitude among patients with the common forms of retinitis pigmentosa (RP). METHODS Visual field equivalent diameter to the V4e white test light of the Goldmann perimeter was correlated with log ERG amplitude elicited by 0.5 Hz or 30 Hz full-field flashes of white light. Primary analyses were con...
متن کاملContrast sensitivity and color vision in eyes with retinitis pigmentosa and good visual acuity: correlations with SD-OCT findings.
BACKGROUND AND OBJECTIVE To investigate the morphological substrate of the changes in visual function in eyes with retinitis pigmentosa and good visual acuity using spectral-domain optical coherence tomography (SD-OCT). PATIENTS AND METHODS A total of 30 eyes of 17 patients with retinitis pigmentosa and visual acuity of 20/40 or better underwent contrast sensitivity and color vision testing. ...
متن کاملCorrelation between optical coherence tomography and multifocal electroretinogram findings with visual acuity in retinitis pigmentosa
INTRODUCTION Our purpose was to study the correlation between the macular morphology and function in eyes with retinitis pigmentosa (RP). METHODS Sixty-six eyes from 33 patients with RP and with different visual acuity (VA) were studied using optical coherence tomography (OCT) and multifocal electroretinogram (mfERG). Correlation analysis was performed between VA, macular thickness, mfERG amp...
متن کاملMethod for deriving visual field boundaries from OCT scans of patients with retinitis pigmentosa
The location of the loss of the inner segment (IS)/outer segment (OS) border, as seen with frequency domain optical coherence tomography (fdOCT), was determined on fdOCT scans from patients with retinitis pigmentosa. A comparison to visual field loss supported the hypothesis, based upon previous work, that the point at which the IS/OS border disappears provides a structural marker for the edge ...
متن کامل[The relationships between visual disability and visual scores in patients with retinitis pigmentosa].
PURPOSE To evaluate the relationship between visual disability and visual scores in patients with retinitis pigmentosa. METHODS The relationship between visual disability and visual scores (visual acuity and visual field) were investigated in 93 patients with retinitis pigmentosa. The visual disability of each patient was evaluated using a questionnaire (a total of 35 questions in 7 sections ...
