Q12: Congenital lens malformations
Congenital lens malformations are a group of conditions present from birth, that involve abnormalities in the development of the lens of the eye. The lens is a clear structure within the eye that focuses light onto the retina so that images can be seen clearly. When the lens doesn't form correctly, it can lead to a variety of vision problems. These can range from minor blurring of vision, to severe visual impairment. This group of conditions may be caused by genetic factors, maternal illnesses during pregnancy, or exposure to harmful substances before birth. Symptoms depend on the type and severity of the malformation and may include blurry vision, difficulty seeing fine details or bright colors, and issues with glare or night vision. These conditions generally do not progress or worsen over time, since they are a result of how the lens formed before birth. They directly affect the visual system.
