RETINAL THICKNESS IN THE MACULAR REGION IN NORM AT A YOUNG AGE ^{[№ 12 ' 2015]}
The purpose of the study was to obtain normative parameters retinal thickness in the macular region. The thickness of the retina was measured at 76 ophthalmological healthy volunteers using an optical coherence tomograph Cirrus HD-OCT 5000. Used a standard protocol Macula Cube 512 х 128. For the center of the macula (within 1 mm) average thickness of the retina was 249.41 μm ± 15.50 μm (220–284 μm). Macula (within 1 to 3 mm): upper — 324.16 μm ± 11.72 μm (296–347 μμm), nasal — 323.03 μm ± 11.90 μm (296–348 μm), lower — 320.31 μm ± 10.78 μm (293–339 μm), temporal — 310.41 μ m ± 13.57 μm (265–344 μ m). For a perimacular region (within 3–6 mm): upper — 279.79 μm ± 10.97 μm (250–305 μm), nasal — 295.49 μm ± 10.97 μm (273–319 μm), lower — 269.20 μm ± 9.86 μm (248–295 μm), temporal — 263.99 μm ± 10.24 μm (242–287 μm). The average thickness of the retina was 281.66 μm ± 9.34 μm (259–298 μm), the average volume of the retina within the investigated region — 10.14 mm³ ± 0.34 mm³ (9.3–10.7 mm³). There were significant differences between the thickness of the retina in the central sectors and in nasal and temporal sectorsperimacular region between men and women: women have lower value. These indicators can be used as reference values to assess the reduction in the thickness of the retina as a result of various degenerative processes, or to determine the degree of increase in retinal thickness at its swelling.
