5. Axenfeld-Rieger syndrome
Axenfeld-Rieger syndrome refers to a group of conditions that can impair the development of the eye. The iris and cornea are the most commonly affected parts of the eye in patients who suffer from Axenfeld-Rieger syndrome. Furthermore, half of all patients with Axenfeld-Rieger syndrome will develop glaucoma as well which is a condition that increases the pressure within your eyes — potentially causing various problems such as hyperopia and even vision loss in some extreme cases.
Other symptoms of Axenfeld-Rieger syndrome beyond hyperopia include abnormally small teeth as well as heart defects. The syndrome can be passed down hereditarily. That being said, the severity of the symptoms that the child will experience doesn’t have to be identical to the parents. In some cases, it is less severe, while in other cases it’s more severe, and the severity seems to be random in the way that it varies.
