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:
Perimeter of a Circle. Perimeter is the distance around a closed figure and is typically measured in millimetres (mm), centimetres (cm), metres (m) and kilometres (km). These units are related as follows: 10 mm = 1 cm 100 cm = 1 m 1000 m = 1 km The word 'perimeter' is also sometimes used instead of circumference.olution: Given that: Diameter of the circle (D) = 4.4 cm. We know the formula to find the perimeter of the circle if the diameter is given, namely ÏÂ· D. Substitute the diameter 4.4 and Pi value as 3.14 in the above formula.
