The Prevalence of Cataract in Children.

Cataract is the leading cause of childhood blindness in developing countries. Early detection and treatment of childhood cataracts can reduce the burden of blindness in the nation. Often the etiology of pediatric cataract is idiopathic; however, genetics play a role in the development of congenital cataract. According to epidemiologists, one-fourth of cases of congenital cataracts are hereditary. Gene responsible for the development of cataract is identified using gene mapping, which helps to prevent future blindness in the family. Cataracts can also present with systemic disease, microphthalmia, microcornea, and aniridia. The presentation of cataracts varies in individuals, some are symptomatic while others are asymptomatic. Parents after noticing strabismus and leukocoria bring their children to an ophthalmologist. Early diagnosis can restore visual function in cases of congenital cataract. In young babies, the type of cataract is determined using slit-lamp examination and examination under anesthesia in OR. Most cases of pediatric cataracts are accidental findings during routine checkups. On direct ophthalmoscopy, red reflex is not appreciated in cases of cataracts. Advancing technology changes the ophthalmologist's approach to pediatric cataract surgery, improving postoperative refractory function. In children, minor incision surgery was preferred to heal early. An appropriate choice of intraocular lens (IOL) should be made for implantation in a child's eye to avoid postimplanted complications. Inflammation and amblyopia affect the outcome of treatment. Complications of cataract surgery include posterior capsule opacification, glaucoma, inflammation, and uveitis.
