In the English county of Norfolk, a girl was born without an iris and is forced to wear sunglasses every day. This is reported by the Daily Mail. Two-year-old Rhiannon Kay suffers from a rare congenital aniridia disease that is associated with photophobia. Due to the lack of an iris, her eyes cannot control the intensity of the incoming light. Parents are careful to ensure that the blinds are lowered in the house during the daytime. Going out, the girl wears a hat and sunglasses at any time of the year.
With age, young Kay developed nystagmus (involuntary repetitive eye movements of high frequency) and cataracts. In addition, the girl has myopia. Doctors say that aniridia can trigger kidney cancer. "It's scary to assume that your child can get cancer," admitted the girl's 36-year-old mother Teresa Kay (Teresa Kay). “However, she has such a keen hearing. She can hear a car stop at our house, although I cannot hear it,”Teresa said.
Aniridia occurs in only one in 75,000 children around the world. The disease is accompanied by a pronounced decrease in visual acuity, photophobia, horizontal nystagmus and sometimes congenital glaucoma. In April, a resident of the British city of Kingston-Veneer-Hull was reported to have avoided sunlight for his entire life due to a rare hereditary disease. At 18 months old, Joshua Barnfather was diagnosed with pigment xeroderma, a mutation that increases sensitivity to ultraviolet radiation.
