THE CORRELATION BETWEEN THE VISUAL FIELD CHANGES AND SCANNING LASER OPHTHALMOSCOPE PARAMETERS IN PRIMARY OPEN ANGLE GLAUCOMA

Abstract

The currently accepted definition of glaucoma requires the presence of glaucomatous field defect in conjunction with corresponding ONH and RNFL defects. However, it has been widely reported that clinically detectable glaucomatous change in the ONH may precede the onset of white to white visual field defects by up to several years.

One of the major challenges in the management of glaucoma is the early detection of the disease. This may be delayed if diagnosis is made on the basis of the development of a reproducible visual field defect.

Recently, confocal SLO has been used both quantitatively and qualitatively to assess the ONH and the neuroretinal rim. Analysis of the ONH morphometric variables may give us a more objective means of assessment than the currently available methods of visual field analysis.

Our study included 20 eyes of 14 patients with POAG. All patients were evaluated by full medical and ophthalmological examination. Patients were also evaluated by the HRT and the Humphrey instrument twice with 6 months interval and the changes in both instruments were evaluated and correlated.
