If the foreign body fully penetrates into the anterior or posterior chambers, then it is officially an intraocular foreign body. In this case, eye morbidity is much more common. Damage to the iris, lens, and retina can occur and severely damage vision.Any intraocular foreign body can lead to infection and endophthalmitis, a serious condition possibly leading to loss of the eye.amage to the iris, lens, and retina can occur and severely damage vision.

The perimeter of a square would be the sum of the lengths of the sides of the square. Since all sides of a square are equal in length, the perimeter would be 4 times the length of one side of the square. In the example above, the perimeter would be 20 units. The perimeter of any equilateral or equal sided polygon is the number of sides of that polygon times the length of one side. The chart below:
The perimeter is the distance around a closed plane figure. P = 2(l + w) where l is the length and w is the width of the rectangle. Find the perimeter of a rectangular field of length 45 m and width 35 m. So, the perimeter is 160 m.
