Hi Welcome to HCM. I can understand the tough time you are going through with your child. Unfortunately, as your ophthalmologist has told, there is no surgery to reverse the microphthalmia. But, there are a couple of points to consider in your child. 1. The early intervention: The first few years of a child’s development are the most important.  Partially-sighted can experience delays in some areas of their development.  Early Intervention programs provide educational support and information to families that have a young child with impaired vision through, Orientation & Mobility training (O&M). All of your child’s specialists/therapists will work together with the family to maximize a child’s development and helps them reach their full potential.  2. In microphthalmia or too small eye,the bones around the eye called the bony socket,may not grow properly. An opinion of an oculoplastic surgeon must be sought for cosmetic correction of the sockets/ scleral shell/ prosthesis if required. 3. Regular visits with your ophthalmologist should be kept in mind, to monitor treatable conditions like cataract ( for surgical extraction) and retinal detachment( for surgical intervention) and most importantly, to make sure the good eye is maintained Good. 4. A protective glass with polycarbonate lens can be worn in the Good eye to prevent any injury. Hope this helps and take care.
