Multiple causes such as allergies pollutants chemicals viral bacterial and conjunctivitis. If persistent should be investigated.

An inflammation of the iris resulting in blurred vision excessive tearing a small pupil and a red eye.

Iris

admin — Fri, 15 Jan 2010 10:05:35 +0000

The ring of tissue between the cornea and the crystalline lens whose various pigmentation gives rise to its colour. Fair skinned people tend to have blue or green eyes while brown eyes and dark skin combine.

The central hole (pupil) varies in size dependant on the intensity of the light. However,the lighter the iris pigmentation generally the more light sensitive the eye.

Intraocular Pressure (IOP)

The measurement of the pressure of the fluid in the eye by means of a tonometer. Especially important in the monitoring of glaucoma due to the fact that the patient is often unaware of the condition being present until permanent damage has taken place.

Intraocular Lens (IOL)

A plastic lens replacing the removed crystalline lens during a cataract operation.

The new implanted lens will have its power accurately calculated to eliminate the need for distance spectacles regardless of the prescription prior to the operation. Can be used in refractive surgery (clear lens extraction) however, until the multi-focal implant has been perfected the patient will require reading spectacles due to the loss of the eyes focusing system regardless of age.

Intra-capsular Cataract Extration

Surgical removal of the entire crystalline lens. Has more or less been superseded by more advanced methods.

Infant Visual Development

There are 3 stages of Infant Visual Development:

At birth patterns of light and dark but objects are out of focus and blurred.
Birth to 4 months the eyes begin to work together and the vision becomes less blurred with the depth of focus increasing while the development of colour vision is almost up to adult standard.
4 to 6 months coordinated eye and hand and eye movements and skills develop however,it is nateral for one of the eyes to appear on occasions to be out of alignment. Should be investigated if persists.
