On ocular examination, visual acuity was 6/6 in the right eye and counting fingers
(CF) in the left eye.
The extension cohort will include patients with hand motion and counting fingers
levels of visual acuity.
Visual acuity (VA) was counting fingers
from 4 meters.
In this post-hoc analysis, visual acuity data were revisited using the Lange method, which is a less conservative off-chart vision scale when quantifying the difference between counting fingers
and hand motions.
Vision in her left eye was down to counting fingers
at one metre.
His examination showed that his best corrected visual acuity (BCVA) was counting fingers
from 1 meter distance in the right eye, 20/20 in the left eye.
Patients' visual acuity ranged from counting fingers
to 50 cm to 0.4; only the youngest patient (number 1), 16 years old, had the visual acuity better than 0.1 (Table 1).
There was also publication on 5 patients with Lebers Hereditary Optic Neuropathy (LHON) treated in SCOTS with visual acuity gains on the Early Treatment Diabetic Retinopathy Study (ETDRS) of up to 35 letters with Snellen acuity improvements from hand motion to 20/200 and from counting fingers
With regard to visual acuity based on Snellen 6m chart, 83 eyes (69.7%) had a VA exceeding 6/12 (Group I), 12 eyes (10.08%) had VA in the range of 6/18-6/36 (Group II), 9 eyes (7.56%) had VA of 6/60- counting fingers
(Group III), 10 eyes (8.4%) responded correctly to hand movement- light perception (group IV) and 5 eyes (4.2%) had no light perception (group V).
After the completion of treatment, 590(52.21%) of the eyes just retained visual acuity of not more than counting fingers
and 126(11.15%) patients lost their globe.
Mean pre op BCVA was counting fingers
(CF) and mean post op value of BCVA was 3/60.
Sixty eyes (48.8%) were classified as counting fingers
