Has anyone used Dr. Mark Preslan in Baltimore? My DS is about 3 months and his right eye is slightly crossed. I've read they generally fix themselves, but if they still have it by 3 to 4 months old to see I pediatric ophthalmologist. I just checked the CareFirst website and looks like he is the only one within 10 miles of us that specializes in pediatrics. Just wondering if anyone has used him or have other dr recommendations. Thanks.
