Relationship Between Visual Field Sensitivity and Retinal Nerve Fiber Layer Thickness Measured by Scanning Laser Polarimetry and Optical Coherence To…

2009

Purpose: To evaluate the correlation between automated achromatic perimetry (AAP) and the output of two retinal nerve fiber layer (RNFL) analysers: scanning laser polarimetry (GDx-VCC) and optical coherence tomography (OCT). Methods: Quantitative RNFL measurements with GDx-VCC and Stratus-OCT were obtained in one eye from 52 healthy subjects, 38 ocular hypertensive (OHT) patients and 94 glaucomatous patients. All patients underwent a complete examination, including AAP using the Swedish interactive threshold algorithm (SITA). The relationship between RNFL measurements and SITA visual field global indices were assessed by means of the following methods: analysis of variance, bivariate Pearso…

Coroideremia: seguimiento durante un año con polarimetría láser

2008

espanolCaso clinico: Presentamos el seguimiento de un caso de coroideremia que fue sometido a tres campos visuales automatizados blanco-blanco y tres polarimetrias laser (PL) con GDx VCC en el transcurso de un ano. Se encontro un deterioro perimetrico en indices y escotomas. En concordancia, los parametros de retardo de la capa de fibras nerviosas de la retina y los mapas cambiaron en un analisis serial avanzado con GDx VCC en los dos ojos. Discusion: El analisis con GDx VCC puede ser un metodo objetivo y cuantitativo para evaluar la progresion de las distrofias coriorretinianas como la coroideremia. EnglishCase report: We report the follow-up of a case of choroideremia who underwent three …
