This is a case of typical congenital nystagmus with null
point ( at the extreme right gaze ) , this is the point
of the least oscillation and the best VA .
Surgery for nystagmus can be indicated in several
clinical situations. Before considering surgery,
pathologic causes for nystagmus must be ruled out.
Red flags for pathologic nystagmus include:
vertical nystagmus, asymmetric nystagmus, acquired nystagmus, intermittent nystagmus, and nystagmus
associated with other neurological signs.
Surgery for nystagmus causing a
consistently present abnormal head posture is performed
to relocate the position of decreased nystagmus to the primary gaze position.
This can be accomplished by various
means with recession/resection procedures ,
(Kestenbaum/Anderson) procedure
being
the most common. Surgery can be done for
both vertical and horizontal types of nystagmus.
If Nystagmus with null point is
accompanied with horizontal deviation , another
calculation to be added to
(Kestenbaum/Anderson)
procedure .
