Thank you for posting your question.
Epileptic encephalopathy per se means the manifestation of brain damage/affection due to
epilepsy (a disorder of
fits).
Epilepsy could be due to a variety of reasons. It could be due to damage to the developing brain of your child due to insult either before/during or after delivery. It could also be due to a genetic cause.
The drugs iracet and neurolep that you have mentioned are drugs to treat epilepsy while
cortan is a
steroid.
According to the information you have given, your child seems to be have a delay in achievement of social milestones (which include eye contact,social smile, recognition of people, non verbal communication). Apart from this, sole delay in attaining eye contact may also mean that the vision is probably disturbed. This could not only be due to corneal issue (which has been ruled out) but also due to other issues in the eye or brain(probably not ruled out).
Whether your child has a risk of developing
autism or not depends on the study of other developmental milestones ( gross and fine motor and language skills) and also the reason behind the epilepsy.
Thus the first step here would be to find out what kind of epilepsy your child has and what is the reason behind it. Similarly the reason behind absent eye contact should be found out.
It is only by answering the above two questions and by regular monitoring, any more comments can be made on the likely direction of your child's development.
