During the follow-up of our patients, the vision improved and the best corrected visual acuity (BCVA) at the end of three months was 80 EDTRS letters (corresponding to a vision of 20/50 on
Snellen chart ).
This vision ratio is given according to
Snellen Chart that is basic, mostly used and time saving chart in our daily life.
Snellen chart, light perception, ophthalmoscopy and slit lamp examination were used to diagnose CC.
In a well-lighted room,
Snellen chart was fixed on a wall at eye level.
uncorrected distant vision acuity of 20/40 or worse, with the
Snellen chart the frequency of DVI rose to 35.7%.
Use of the Illiterate E
Snellen Chart might also have influenced the high referral figure in this study, by making it harder for Gr R learners to discern the letters, and highlighting laterality difficulties rather than reduced VA.
Visual acuity was measured with a
Snellen chart, both with spectacle correction and with a pinhole occluder.
Horizontal and vertical heterophoria and the stimulus AC/A ratio were determined in the phoropter using the von Graefe method and a 6 x 6 matrix of 20/20 letters on the clinical, near, reduced
Snellen chart [27].
Testing of visual acuity using the
Snellen Chart (the standard eye chart used by eye care professionals to measure visual acuity) showed a significant improvement from baseline 14/20 to 17/20 after two months of treatment with Pycnogenol.
I tested the same subjects again using a standard
Snellen chart at 20 feet.
Her vision was checked with the
Snellen chart after each treatment, and after the sixth treatment, she was able to read the 20/50 line.
