My grand daughter has a unilateral congenital cataract. She is nine years old, we started patching the normal eye at six months of age...her ophthalmologist at Seattle children's hospital recommended patching only and not surgery. In the past year the family has noticed significant drifting in her eye. We took her for an exam and her vision had deteriorated significantly. The cataract has increased in size and the dr is now recommending surgery. I would like to know how great are the risks for developing glaucoma after surgery. We still don't know if surgery will restore her vision to the previous 20/60 that it was at age 5...she now has 20/200. We really would like to know if the benefits will outweigh the risks of the surgery.
The risk of glaucoma, assuming the eye is not particularly small, otherwise malformed, or affected by persistent fetal vasculature, is quiet small at this age. Perhaps less than 5-10%. Not doing the surgery is 100% chance of permanent legal blindness.
