welcome to health care magic
Thanks for query
You have upper eyelid coloboma
which is congenital..
In this condition due to exposure to air even when eyes are closed,,,dryness of cornea and conjunctiva
will occur,,cornea will damage(corneal xerosis) and it will case vision loss
in due course of time.
You have to use artificial tears
to make cornea and conjunctiva wet..and also keep patching the eye in the night..and during sleep.
If the coloboma is small enough then you can manage with artificial tears ...
If the defect is large then go for surgical correction..
There is a modified Hughes procedure for this..Consult Ophthalmologist
for further suggestions..
Go for CT skull and orbits.,why because the condition is associated with other congenital anomalies.
Hope you got answer from me.
