A new and practical test for contrast sensitivity (Arden gratings) was evaluated in retinal diseases and found to be a more sensitive indicator of dysfunction than Snellen acuity. Most patients with acuity of 20/30 or better (e.g., with retinitis pigmentosa or toxic retinopathy) showed diminished sensitivity to finely spaced gratings, while patients with poor acuity (e.g., with cone dystrophy) showed normal sensitivity to coarsely spaced gratings. Grating tests may allow earlier diagnosis and more precise follow-up of retinal disease, but their specificity for particular disorders remains to be established.
一种用于检测对比敏感度的新型实用测试（阿登光栅）在视网膜疾病中进行了评估，结果发现它是比斯内伦视力更敏感的功能障碍指标。大多数视力为20/30或更好的患者（如患有色素性视网膜炎或中毒性视网膜病）对精细间隔光栅的敏感度降低，而视力较差的患者（如患有视锥细胞营养不良）对粗间隔光栅的敏感度正常。光栅测试可能有助于视网膜疾病的早期诊断和更精确的随访，但它们对特定疾病的特异性仍有待确定。
