Demi (F/8) datang untuk pemeriksaan mata, mengadu kabur tengok jauh sejak baru-baru ini. Demi kata adakalanya sakit mata & spek tak selesa pakai tengok phone. Mama kata beliau pakai spek ke sekolah saja & adakalanya pakai spek hadap hp jugak.. dan perasan phone dipegang dekat dengan mata.
Tahap penglihatan tanpa cermin:
R: 6/9-
L: 6/21-
Pemeriksaan menunjukkan:
R: -0.25/-0.50×10 (6/6) [+1.00 blur lens test 6/12-]
L: -1.00/-0.25×180 (6/6) [+1.00 blur lens test 6/15-] [L: mata kiri dominan] L>R
Add: +1.00 (R>L)
When we reduce -0.25 shortsightedness binocularly, vision is fine too
Pemeriksaan lain menunjukkan:
Pemeriksaan Alignment Mata (Cover Test)
NMD @ jauh
small XP, fast recovery @ dekat
– her eyes flutter horizontally (big movement) sometimes
(normal value: orthophoria/NMD-No Movement Detected atau small XP fast recovery)
Pemeriksaan Alignment/Postur Mata (Howell Card) by 6^ Base Down on Right eye
Jauh: 0
Dekat: 4 – 6 XP (bahagian biru) -> 20 XP (extreme of blue) <-> 0 <-> 20 EP (extreme of yellow)
(normal value: 0 – 1 EP or 0 – 3 XP @Jauh & 0 – 6 XP @Dekat)
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 (Maddox Rod)
Jauh: 3 BI
Dekat: orthophoria
(normal value: 0-1 EP or 0-3 XP @Distance and 0-6 XP @Near)
BO/EP = Base Out/Esophoria is misalignment of the eye, eye is deviated inwards
BI/XP = Base In/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
8/10cm, TTN, TTN, 8/12cm, 8/13cm, TTN, 9/14cm
+1.00 NPC: same findings
(normal value: less than 10cm or to the nose, TTN)
Jump Convergence
– slow & hesitant convergence movement, especially left eye
AA (Accommodation/Focusing – eye stamina/ability of eye to focus & sustain seeing near clearly) by RAF rule
R: 22 YO, 22 YO, 22 YO
L: 22 YO, 24 YO, 26 YO
(normal value: AA/usia mata ikutkan usia, YO=years old)
NRA (accommodation analysis – ability to relax accommodation with plus lenses)
+2.50
(normal value: +1.50 to +2.50)
PRA (accommodation analysis – ability to stimulate accommodation with minus lenses)
-0.25
(normal value: -1.37 to -3.37)
MEM (Accommodation lag – to measure accommodation response seeing near target)
R: +1.25
L: +1.50 (dim reflex)
(normal value: +0.25 to +0.75)
Facility (Accommodation facility – ability to change focus: far to near or near to far) by Flipper +/- 2.00 held at 18cm
BE: 13 cycle per minit(cpm), difficult minus lens(2nd lens)
R: 16 cycle per minit(cpm), difficult minus lens(2nd lens)
L: 16 cycle per minit(cpm), difficult minus lens(2nd lens)
– when flipper +/-2.00 held at further away, failed minus lens
(normal value: 1 cycle = 2 perkataan dibaca
Monocular or R/L: 6cpm to 16cpm
Binocular or BE-both eyes: 4cpm to 14cpm)
Demi berasal dari Sabah.. datang untuk cuti sekolah.. spek tidak dibawa & beliau dibawa mama & nenek, our customer friend aunt Lucy to us for eye examination. Memandangkan yang komplen ini baru-baru ini saja, kita reinforce proper visual hygiene.. betapa pentingnya untuk kita pegang phone dalam jarak yang sihat(jarak siku kita) dengan mesti ambil rehat antara masa skrin. We cannot emphasise enough in holding phone at a healthy Harmon distance & taking a regular break in between screen time. Nampaknya, stamina mata Demi ada kurang tapi komplen mata baru-baru ini saja, kita nasihatkan untuk pantau balik selepas buka sekolah nanti sekiranya beliau masih ada komplen yang sama.
