ABSTRACT
We quantitatively analyzed the changes of the(retinal) threshold sensitivities between normal status and dilated emmetropic status, and between dilated emmetropic status and -1.0D induced myopic status. Three consecutive visual field examinations by Humphrey Field Analyzer C-30-2 threshold test and STATPAC program were performed in 36 eyes of 21 normal subjects who ranged in age from 23 to 40 years. The results were as follows 1) There was a statistically significant decrease (0.87 +/- 0.91dB) in the mean threshold sensitivity within the central 30 degrees at the dilated emmetropic status(27.90dB) as compared with the normal status(28.77dB) (p=0.0001). 2) There was a statistically significant decrease(0.99 +/- 0.61dB) at -1.0D induced myopic status(26.91dB) as compared with the dilated emmetropic status(27.90dB) (p=0.0001). 3) After dilation, the mean threshold sensitivity between 20 and 30 degrees of field showed statistically significant decrease as compared with thosE' within the central 20 degrees of visual field(p0.05). Therefore, we emphasize the importance of consistent pupillary size and correct refractive state in performing the serial automated visual field tests.
