While it isn’t overly common, there is a type of open-angle glaucoma in kids, referred to as congenital glaucoma, or infantile glaucoma. Inherited, the drainage area does not develop properly before birth. As such, an enhanced pressure within the eye can cause vision loss and an enlarged eye, as the optic nerve is damaged.
Why the enlarged eye? A young child’s eye will get larger as a result of added intraocular pressure, after all, it is more flexible than an adult’s eye.
The bad news is that it can be frightening as a parent to find out that your little one has glaucoma; however, the silver lining is that early detection and treatment (whether that be surgery or medication, etc.) can help to preserve your child or infant’s eyesight.
