Capacidad diagnóstica del HRT-II y de las perimetrías TOP, PULSAR y FDT en pacientes sospechosos de sufrir glaucoma

Abstract

The most effective indices were maximum contour elevation, reference height and PULSAR-sLV, although the inclusion of the optic nerve head assessment in the selection of the GS sample may have favored the HRT-II results.

Oculus–Spark Perimetry Compared with 3 Procedures of Glaucoma Morphologic Analysis (GDx, HRT, and OCT)

“…initial stages of glaucoma, retinal dysfunction manifests as alterations in the homogeneity of responses more than as the presence of evident defects. This has been shown in examinations using the TOP strategy with both conventional stimuli (18)(19)(20) and Pulsar stimuli (21)(22)(23). The present study with the Spark strategy showed that MD obtained the maximum diagnostic capacity, but PSD was not significantly different from MD and also from the best morphologic indices and possibly even better, when these indices were sensitive to optic disc size.…”

Detection of morphological and functional progression in initial glaucoma

“…This, and the relative agreement in diagnoses of progression, suggests that TNT manages to detect progression more efficiently than the other procedures analysed. The slopes proved significantly more pronounced in Pulsar, possibly due to its greater sensitivity to glaucomatous damage,9 20 21 but also because of greater stability of its results with respect to WW and FDT,22 as well as the perimetric strategy it uses 23 24…”

Vergleich der Ergebnisse der Flimmerperimetrie (Prototyp versus kommerziellem Perimeter)

“…Der dargebotene Bewegungsreiz stimuliert das Kontrastsehen sowie die zeitliche und räumliche Auflösung, wodurch das magno-und parvozelluläre Ganglienzellensystem stimuliert werden, mit stärkerer Reizung des magnozellulären Systems [11]. Die Pulsar-Perimetrie kann initiale glaukomatöse Defekte bei okulärer Hypertension aufdecken, obwohl noch keine morphologischen oder funktionellen Anzeichen eines glaukomatösen Schadens nachweisbar sind [14][15][16][17][18]. Zusätzlich zeigte es sich vorteilhaft beim juvenilen Glaukom [19] und Offenwinkelglaukom [20,21] sowie insbesondere beim frühen Glaukom [22].…”
