Illinois Eye Associates offers a variety of technologically advanced special testing

Visual field testing is important in the diagnosis and management of glaucoma, as well as other ocular diseases. It is used to confirm that glaucoma has affected the visual field, to evaluate the severity, and to monitor for progression. An automated instrument is used to map the visual fields. The patient looks straight ahead into a bowl-shaped area and the instrument's computer randomly flashes points of light around different places in the bowl. The patient clicks a switch whenever he/she sees the light, which varies in brightness.

At Illinois Eye Associates, photographs of the back of the eye may be used, if necessary, to document the health of the optic nerve, vitreous, macula, retina and its blood vessels. The photographs are used for comparison, documentation, and sometimes to diagnose certain eye conditions.
Because fundus photography is a highly specialized form of medical imaging, it can’t be done with an ordinary camera. It requires a customized camera that is mounted to a microscope with intricate lenses and mirrors. These high-powered lenses are designed so the photographer can visualize the back of the eye by focusing light through the cornea, pupil and lens.

In the fitting of contact lenses and in certain ocular diseases, it is helpful to know the precise shape of the cornea. Several methods of measuring the corneal shape have been used. A corneal topographer is a computer which uses a “snap shot” image of the cornea to produce a printout of the corneal shape using colors to identify different steepnesses, much like a topographic map of the earth describes changes in the land surface. The doctor can use these maps to evaluate the corneal size, shape, and steepness.
