The study describes cases of patients screened for worse vision and headaches. We are trying to point out we can measure minus diopters even at latent hypemetropes. These patients come to a doctor for a variety of problems that may be caused by inadequate correction of ametropia. It is necessary to know about this possibility, and rather perform cycloplegia in sporadic cases.
Patients were measured at autorefractometer without mydriasis, and then after using UNITROPIC 1% or CYCLOGYL 1%. Both of these substances induce cycloplegia. Visual acuity with the best correction was tested with and without cycloplegia.
After cycloplegia, a significant change in both objective and subjective refraction was detected in most of the selected patients. This change was within the meaning of a shift to hyperopia. Subsequent adjustment correction led to resolving of problems.
The work should highlight the necessity of an individual approach of prescription of the best correction. Not always an autorefractometer gives correct information, the real-needed correction is completely different in some cases.
该研究描述了因视力下降和头痛而接受筛查的患者案例。我们试图指出,即使对于潜在远视患者,我们也能够测量负屈光度。这些患者因屈光不正矫正不足可能引发各种问题而前来就医。有必要了解这种可能性,并且在散发病例中最好进行睫状肌麻痹验光。
患者在未散瞳的情况下使用自动验光仪进行测量,然后使用1%复方托吡卡胺或1%阿托品眼膏后再次测量。这两种药物均可诱发睫状肌麻痹。在有或没有睫状肌麻痹的情况下测试最佳矫正视力。
在大多数选定患者中,睫状肌麻痹后客观和主观验光均出现显著变化。这种变化表现为向远视方向偏移。随后调整矫正措施后问题得到解决。
该研究应强调采用个性化方法开具最佳矫正处方的必要性。自动验光仪并非总能提供正确信息,在某些情况下实际所需的矫正与自动验光仪结果完全不同。
