生理盲点测定:(Physiological Blind Spot Determination)生理性盲点,通常是指视盘区域。

断人体维生素A营养状况的指标之一。测定时用阈值视标在颞侧水平径线15°处静点呈现约1s,确信受检眼未看见后向8个方向放射移动视标,记录从不可见区到可见区的交点,8个交点的连线即生理盲点范围。根据测得生理盲点范围的大小,判断体内维生素A的水平。若维生素A供给不足,生理盲点扩大。此时若给予大剂量维生素A,则24h可缩小至正常范围。

Break one of target of state of nutrition of A of human body vitamin. Mark is inspected with threshold value when determining in line of path of Nie side level 15 ° are in quiet place to appear make an appointment with 1s, believe firmly look getting check did not see backward 8 direction are radiative and mobile inspect mark, the record arrives from sightless area the node of visible area, of 8 node connect a line namely physiology scotoma limits. The basis measures the volume that gets physiology scotoma range, judge the level of A of the vitamin inside body. Be like vitamin A supply deficiency, physiology scotoma expands. Right now if give large dose vitamin A, criterion 24h can narrow to normal limits.
