Astigmatism is a common, mild and easily treatable imperfection in the curvature of your eye. The condition can cause blurred vision. Astigmatism occurs when the front surface of your eye (cornea) or the lens, inside your eye, has a slightly different surface curvature in one direction from the other. Instead of being even and smooth in all directions, the surface may have some areas that are flatter or steeper.

Hydrocephalus occurs when excess fluid builds up in brain, most often because of an obstruction preventing proper fluid drainage. The excess fluid can push fragile brain tissues up against the skull ? causing brain damage and, if left untreated, even death. Hydrocephalus is sometimes present at birth, although it may develop later. The excessive accumulation of CSF results in an abnormal widening of spaces in the brain called ventricles. This widening creates potentially harmful pressure on the tissues of the brain.
