摘要
目的探讨近视眼患者中心视野的改变情况。方法对眼底相对正常的近视眼患者53例105眼进行中心视野(OCTOPUS101视野计32检测程序)检查并对视野指标进行分组比较。结果近视眼平均敏感度(MS)低于正常,而平均缺损(MD)及丢失方差(LV)超出正常水准。近视程度与视力及MS成中高度负相关、与MD成中度正相关,均P<0.01),与LV无相关关系。54眼中51.43%的近视眼出现了视野损害,视野损害率随近视程度的增加而上升,差异有高度统计学意义(P<0.01)。视野损害类型可归纳为中心暗点及类青光眼损害。结论近视眼患者存在中心视野损害,且在中度近视这种损害已很常见,视野损害完全可发生在眼底正常的近视眼。建议如同对青光眼一样对近视患者进行定期的视野检查以指导其早期诊断和干预。
Objective To study the changes of the centric threshold perimetry in myopia. Methods Fifty-three cases（105 eyes） of myopia with no posterior polar retinal changes under ophthalmoscopic examination were divided into groups based on their degree. The centric threshold perimetry of all eyes were tested by OCTOPUS 101 and compared. Results Mean sensitivity （MS）, mean defect （MD） and loss variance （LV）of myopia were abnormal. That degree of myopia was significantly negatively correlated with MS and visual acuity, while was positively correlated with MD and was not correlated with LV. Fifty-four eyes （51.43%） showed field abnormalities and the rate of the abnormality increased with the degree of myopia. The difference was significant exists in myopia, especially is common in middle and high degree myopia. Such impairment can occur in myopia with no posterior polar retinal changes under ophthalmoscopic examination. It is suggested that making centric threshold perimetry test as regular in myopia as in glaucoma. It is helpful in early diagnosis and treatment of myopia.
