JWann (M/26) came for eye examination, with complaints of blurry far vision with existing glasses of 10years.
Vision without glasses
R: cannot see 6/120
L: cannot see 6/120
Vision with existing glasses
R: -3.00/-2.00×180 (6/18-)
L: -5.25/-1.75×170 (6/9-)
Examination shows:
R: -4.00/-2.00×5 (6/6) [R: dominant right eye]
L: -5.75/-1.75×165 (6/6)
Add: +1.00
Retinoscopy
R: -4.00/-2.00×5
L: -5.75/-1.75×165
Other assessments show:
Examination of Eye Alignment/Vergence (Cover Test)
NMD @ Distance
small EP, fast recovery @ Near
(normal value: orthophoria/NMD-No Movement Detected or small XP, fast recovery)
EP = Esophoria is misalignment of the eye, eye is deviated inwards
XP = Exophoria is misalignment of the eye, eye is deviated outwards
Examination of Eye Alignment/Posture (Howell Card) by 6^ Base Down on Right eye
Distance:0
Near: 1 EP (yellow part)
+1.00 Near: 0 – 2 XP (blue part)
(normal value: 0-1 EP or 0-3 XP @Distance and 0-6 XP @Near)
EP = Esophoria is misalignment of the eye, eye is deviated inwards
XP = Exophoria is misalignment of the eye, eye is deviated outwards
NRA (Accommodation analysis – ability to relax accommodation) by plus lens
+1.75
(normal value: +1.50 to +2.50)
PRA (Accommodation analysis – ability to stimulate accommodation) by minus lens
-0.75
(normal value: -1.37 to -3.37)
Facility (Accommodation facility – ability to change focus: far to near or near to far) by Flipper +/- 2.00
R: 9 cycle per minit(cpm), difficult with minus lens
L: 9 cycle per minit(cpm), difficult with minus lens
BE: 4 cycle per minit(cpm), difficult with minus lens
+1.00 BE: 7 cycle per minit(cpm)
(normal value:
Monocular or R/L: 6cpm to 16cpm
Binocular or BE-both eyes: 4cpm to 14cpm)
JWann is slightly esophoric at near. When tested with added plus lenses of +1.00 at near, his near posture is normalised to 0-2 exophoria. The same goes to his accommodation facility.. in which he can change fixation & clear his focus even faster about double the efficiency with the added plus lens.
Getting an annual eye examination (if not once in 2years max) is absolutely a necessity. We want to ensure that our eyes are pampered with optimum vision, showered with love & care regularly.
Let us be in touch with your eye care practitioner, we collaborate & go together along the journey in prioritising our own eyes & vision, because we take charge of it. Not only we can do much more to minimise avoidable blindness (just by having you coming into our practice) and so with the absolutely pressing concern now is to prevent being myopic or worse highly myopic.. because….. research has predicted that half of the world population will be myopic by 2050.. this is alarming and it is about us.
