Ern (F/10) came for eye examination, complaining slightly blurry far vision seeing whiteboard at school and tired eyes during near work. Mother said that she will remove glasses to see near.
Vision with existing glasses 3years: (of cycloplegic refraction, power after put eye drop – obtained from eye specialist clinic)
R: -3.00/-0.75×170 (6/7.5-)
L: -3.25/-0.75X175 (6/7.5-)
Examination shows:
R: -3.25/-0.75×170 (6/6)
L: -3.50/-0.75×175 (6/6)
Relax Add: +2.00
Other assessments show:
Examination of Eye Alignment/Vergence (Cover Test)
EP @Distance & Near (Near > Distance)
(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
NPC (Convergence – ability of eye to maintain a single clear near image) by RAF rule
7cm, 7cm, 7cm (Right eye moved in nasally/partially not seen – eye converges too much during convergence)
(normal value: less than 7.5cm)
Examination of 3D Vision/Stereopsis (Titmus Fly)
20″
(normal value: 20″)
Examination of Eye Alignment (Howell Card)
Distance: 3 EP
Near: 3 -> 7 -> 9 EP
+1.00 Near: 3 -> 5 EP
+2.00 Near: 1 -> 3 EP
(normal value: 1 EP-0 or 0-3 XP @Distance; 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
Ern may have Convergence Excess or Basic Esophoria at Distance & Near. We will let her wear optimum correction with Relax Add +2.00 full time.
We will see her again after she wears the new glasses for 4-6weeks.
