...The Eye in CHARGE
Structural & Sensorial Deficit Association With Visual Functioning
- APSEA functional vision assessment was possible in 6/8 patients
- 83% did not attend to distant objects
- 50% had difficulty maintaining eye contact
- 83% brought objects close to their face to view them and 66% showed little interest in objects located superiorly
- 16% of patients had difficulty scanning an object
- visual deficits good indication of functional ability
- patients wtih least visual deficity performed the greatest number of opththalmologic, orthoptic, electrodiagnositcic, neurologic and APSEA tests--they had greater then 6/60 vision in at least one eye no optic nerve involement if coloboma present (37%)
- Greatest impaired where little testing was possible typically had extensive bilaeral chorioretinal colobomas involving ON OU (37%)
Conclusion
- frequent findings are bilateral VIII, VII, I nerve and isolated RIO involvement
- bilateral chorioretinal coloboma is a frequent feature
- astigmatism and anisometropia are common
- strabismus and amblyopia is a common feature
- further longitudinal studies are needed to answer our final two questions:
1. Are some of the performance on visual function tests neurologic in nature as opposed to related to visual deficits
2. What behavioral characteristics of CHARGE syndrome are related to visual function
Conclusion
It is clear that early recognition and managment of sensory problems (visual and auditory) is crucial in order to ensure the best psychomotor development.
