Q13: Congenital malformations of anterior segment of eye
Congenital malformations of the anterior segment of the eye refer to a group of conditions present from birth which impact the front part of the eye, specifically the area from the back surface of the cornea to the front surface of the lens. These disorders can include inherited defects of the cornea, iris, lens, ciliary body, or aqueous fluid pathways. Such defects could be due to genetic reasons or environmental factors during pregnancy. Common symptoms for these conditions may include blurry vision, sensitivity to light, eye discomfort, or the appearance of halos around lights. These conditions may affect a person's visual acuity and could progress, worsening over time if left untreated. Conditions affecting this area of the eye can have serious impacts on the individual's vision and overall eye health.
