估计白内障患者尤其是晶体浓密混浊者的视网膜状态和黄斑机能,是困难的。较为常用的方法是查光定位或色觉,但这些方法对浓密的白内障是不可靠的。视网膜电流图和视诱发电位虽然可靠,但设备复杂,且需培训操作人员。作者认为两种新的主观检查法,即蓝视野内视试验(BFE)和Lotmar氏视力表试验,设备简单,检查速度快,容易操作,可以广泛应用。病例和方法:作者检查了60例60眼,全部都是在全麻或局麻下行囊内冷冻摘出术,术中、术后均无并发症。术前进行全面的客观检查和功能检查,包括BFE试验和Lotmar氏
It is difficult to estimate the retinal status and macular function of cataract patients, especially those with crystal-dense turbidity. The more common method is to locate the light or color vision, but these methods are not reliable for dense cataracts. Although the retinal current pattern and apparent evoked potential are reliable, the equipment is complex and requires training of operators. The authors believe that two new subjective tests, the Blue Field Visual Field Test (BFE) and Lotmar’s Eye Chart Test, are simple devices, fast inspection, easy to operate and widely available. Cases and Methods: The authors examined 60 cases of 60 eyes, all under general anesthesia or intracapsular cyst by frozen extraction surgery, intraoperative and postoperative complications. Preoperative comprehensive objective examination and functional tests, including the BFE test and Lotmar’s
