To analyze statistically the real effectiveness of TNO stereotest for the diagnosis of microesotropia in young patients in daily practice.
We considered 312 patients whose age ranged from 3 to 18 years (mean age 7.5 years) suspected to be microesotropic. All underwent a full orthoptic and ophthalmologic examination. The TNO stereotest was presented at a distance of 40 cm with the patient wearing red-green glasses. The Paliaga 8-D base-in test was considered the gold standard diagnostic test to detect microesotropia.
The specificity of the TNO stereotest from the collected data was 98%, the sensitivity 94%, the positive predictive value 80%, the negative predictive value 99%, and the likelihood ratio 47.
It is important to use the TNO stereotest in clinical daily practice to detect microesotropia, but considering some bias: the age of the young patients, the difficulties encountered in understanding some figures, and the presence of a stereoscopic status even in microtropic subjects.
