Cataracts are the greying or opacity of the crystalline lens, which can be caused in children by intrauterine infections, metabolic disorders, and genetically transmitted syndromes. [56] Cataracts are the leading cause of child and adult blindness that doubles in prevalence with every ten years after the age of 40. [57]
Cataract surgery is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [3] Over time, metabolic changes of the crystalline lens fibres lead to the development of a cataract, causing impairment or loss of vision.
The most common congenital infection to cause congenital cataracts is Rubella. [4] Rubella is especially common, with a higher incidence in India. [4] Rubella is characterized by a triad of features: congenital cataracts, sensorineural hearing loss, and patent ductus arteriosus (a congenital heart condition). [4] Trauma can cause cataracts in ...
Intraocular hemorrhage may be caused by physical trauma (direct injury to the eye); ocular surgery (such as to repair cataracts); or other diseases, injuries, or disorders (such as diabetes, hypertension, or shaken baby syndrome). [2] Severe bleeding may cause high pressure inside the eye, leading to blindness.
Central cataracts, due to the lens clouding, disperses the light before it can reach the retina and is a common cause of hemeralopia and photoaversion in the elderly. Cancer-associated retinopathy (CAR), seen when certain cancers incite the production of deleterious antibodies against retinal components, may cause hemeralopia.
The primary causes include post-cataract surgery, certain medications, and, less commonly, neurological or ophthalmological conditions. Post-cataract surgery is a common cause, as replacing the natural lens with a synthetic one increases exposure to blue light, leading to temporary blue-tinted vision. This effect usually resolves as the eye adapts.
