Product Details:ZABBYS Maddox Wing TEST

• Maddox Wing a quantitative and subjective method of measuring the size of a strabismic deviation by dissociation of the eyes brought about by two septa which are placed in such a way as to present fields to either eye separated by a diaphragm at the centre.

Maddox Wing Test This apparatus affords a rapid means of detecting the presence of heterophoria near vision and measuring its amount in prism dioptres, on the horizontal and vertical scales. Procedure The patient rests the face-piece on his or her nose and looks through the two slits. The  upper  oblique  wing  divides  the  visual  field  into  two  halves  so  that  the  left  eye  sees the  scale  towards  which  the  white  arrow  points  and  the  right  eye  sees  the  arrow.  The character  and  degree  of  the  deviation  can  then  be  determined  at  once  from  the  apparent position of the arrow on the scale. The  vertical  screen  cuts  off  the  red  arrow  from  the  left  eye  and  the  red  vertical  scale  from the  right  eye,  so  that  any  vertical  deviation  can  be  detected  rapidly  and  measured  from the apparent position of the red arrow on the vertical scale. Cyclophoria,  if  present,  can  be  measured  by  adjusting  the  moveable  wire  forming  the shaft of the red arrow until it appears to the patient to be parallel with the horizontal scale. When  carrying  out  the  Maddox  Wing  Test  the  apparatus  should  be  directed  downwards so  that  the  eyes  are  in  a  position  similar  to  that  adopted  in  near  vision  under  normal ‘every day’ conditions. Cleaning Instructions Clean with warm soapy water using a clean soft cloth.
