Abstract
Aim of the work
Proper assessment and management of cases with congenital nystagmus either sensory defect or congenital idiopathic that can be attended to Minia University Hospital outpatient clinic.
Conclusion
Congenital nystagmus either SDN or CIN have the same features on basis of nystagmus wave form, so, electrophysiological tests must be done to differentiate between both. And both can be differentiated from the neurological nystagmus by presence of a neurological deficit in the later.
Most congenital SDN/CIN is jerky nystagmus and varies in degrees according to the quick phase fastness.
In our study patients with SDN/CIN were diagnosed, evaluated and managed by different modalities including spectacles, contact lenses, prisms and surgically.
Spectacles and contact lenses proved its efficacy in managing patients with errors of refraction.
Mild head turn can be corrected with prisms.
Large Recti Recession procedure decreases the amplitude of nystagmus, shifts the null zone and compensates the head position for short time management.
Long term follow up is needed to evaluate the surgical results especially the restriction of the gaze movements and recurrence of nystagmus.
Nystagmus never lead to blindness and the problem is being the poor vision especially at school ages.
The present study strongly recommends careful evaluation of nystagmus cases, accurate diagnosis and to insure the best way of managing the cases with congenital nystagmus.
