"Through My Lenses"
Salamwhy do you decide to prescribe plus rx on this pt even she is suffering exotropia?
@The Travelertq my fren for willingly posted this case =))slm,we decided to prescribe modify plus RX in order for this little ling-ling can achieve best vision acuity since she's now is in kindergarten and need sharp vision to do a lots of distance and near tasks. in addition we also found stability in refraction power during last 3 visit..for time being, with this RX doesn't help her on correcting XT....
it is because:-retinoscopy inidicated she is hyperopia -with the ret RX her vision improved significantly esp at near- plus power( hyperopia) is mainly to prevent amblyopia-PCT with plus Rx given (hyperopia) is the same magnitude as PCT without plus Rx (plus Rx dont interrupt/worsen her magnitude of XT
Happy discussing here
miss farahiyah....-->" =)) ??" (bruno mar- u can counting on me :)based on my previous statement - plus rx is given mainly to prevent amblyopia while not disrupt/worsen her XT ..my justification :-her XT is 25pd BI (dist) & 40ps BI (near) is very large deviation..-so i guess,her accommodation convergence (low AC/A) unable to sustain/inadequate for her to get the the clear image..thus produce blurred image..-so the correction for Rx is important prevent amblyopia (eventhough plus Rx)- beside,Rx correction is useful to stimulate the sensory conditions before surgery.....kn?
also...agreed with farahiyah...Plus Rx not for correcting her XT~~~~ (^^)vwhat if (with u/correct).. -the plus Rx worsen her XT but maintain VA..or..-the plus Rx reduce VA but maintain the XT magnitude?which we should concern more? VA( prevent amblyopia) or her magnitude XT?hohoo~~~ =((
to decide which one is more crucial, you must remember the step of giving treatment on pt..pls someone list down n elobrate them forall the readers
hi everyone,,,=)as we know the main crucial things is to maintain the VA as if the VA reduce, the eyes will become lazy eye and the patient wouldn't notice when the eye deviate as the eye is no longer functioning well and she will tend to use the better eye..this will result to constant deviation and even become larger in magnitude..the step on giving vision therapy are as below: 1. correct refractive error 2. equalise VA 3. equalise accomodation 4. increase smooth vergence 5. increase step vergence 6. fusionanyway, this is from my perspective if there are mistakes or any other answer, i will be happy to hear..tq..(^_^)
oh ya thanks to lovely arifah, as she willing to post this case...=)
salam guys... i would like to add 1 step on vision therapy given by huda. if i'm not mistaken, the 4th step should be create physiological diplopia.after we increasing the diplopia awareness, then we can improve the vergence....:D then, try to focus as close as possible. just wanna share, for vision therapy for divergence excess we can use Brock String and for near XT we use Dot card :)
