Sažetak
The aim of study was to establish which level of myopic refractive error influences visual field defects in automated static perimetry, if these defects are typical, and if optimal correction normalized the visual field. The study included 100 patients (200 eyes) divided into three groups according to the severity of the myopic refractive error: group A (till –3.25 Dsph), group B (–3.50 Dsph to –5.25 Dsph) and group C (–5.50 Dsph to –8.00 Dsph). The control group included 20
emmetropes (40 eyes). This study confirms that optimal corrected and uncorrected myopia up to –3.25 Dsph does not produce
quantitative visual field defects, when tested by static automated perimetry. Even in optimally corrected myopics, with myopia higher than –5.50 Dsph, visual field defects on gray scale can be found. Defects are in the intermediary zone with more prominent defects in the upper quadrants. Visual field indices (MD, MS, LV, RF) were completely normalized.
