Abstract :
Aim:
This study aims at finding an effective optical low
vision device for near, which will enhance the reading
speed in patients with dry ARMD.
Objectives:
To suggest the most suitable optical low vision
device for near at reading.
Methods:
43 patients with dry ARMD were taken with
detailed history taken. BCVA done for distance with Log
MAR and for near with Bailey Lovie chart. Calculation
for magnification done for near. After LVDs trial done
for near the MN read chart was given to the patient to
read the chart with each given devices (Stand, Hand-
held, Bar, Dome and Spectacle magnifiers) for reading
and the time taken to read the chart was noted. The
reading speed was calculated as a words per minute
(WPM). Reading acuity and critical print size were also
calculated with each device.Results:
The mean magnification for all the five magnifiers
(Stand, Hand-held, Bar, Dome and Spectacle magnifiers)
was 3.2±0.79. The maximum reading speed in wpm was
found with Hand-Held magnifier (127.33 ± 43.25)
whereas minimum reading speed was with bar magnifier
(89.07 ± 51.46). All these patient (N=43) had a best
corrected visual acuity between 0.48 to 1 log MAR in the
better seeing eye.
Conclusion:
All magnifiers shows the better and functional
reading speed in all the Dry ARMD patients taken.
Although the average reading speed was high with hand-
held magnifier. So, we can conclude that every
magnifiers are equally better in case of reading speed
and any of them can be suggested to these patients
depending upon their comfortability.
