Pulsarperimetrie

Abstract

We present a review and update on Pulsar perimetry, which combines temporal frequency, contrast and spatial frequency stimuli. The effects of age, visual acuity, and learning on results are described. Data on threshold fluctuation, signal-to-noise ratio, and the possibility of reducing noise with filtering techniques are provided. We describe its dynamic range and the possibility of compensating for profound defects. Finally, we show the results obtained in normal patients and in those with ocular hypertension or initial glaucoma, as well as an analysis of glaucoma progression.

Computer perimetry in the diagnosis of primary open-angle glaucoma

“…Этот тест основан на предъявлении в течение 500 мс в различных точках ЦПЗ (до 30° от точки фиксации) концентрического стимула размером 5°, пульсирующего с временной частотой 10 Гц, и выполняется при остроте зрения не ниже 0,7. По данным некоторых авторов, результаты Pulsar-периметрии обладают высокой специфичностью (72-95 %) [20,21].…”
