Visual Field testing is an important diagnostic tool in the assessment of the eye’s visual fields. A normal visual field as measured from the central fixation point is 90 degrees temporally, 50 degrees nasally, 50 degrees superiorly and 60 degrees inferiorly. Many eye conditions can cause a narrowing of the field of vision, examples are Retinitis Pigmentosa, Glaucoma, etc. Other conditions for example Macular degeneration will only affect central vision. Even space occupying lesions, for example tumors in the brain may cause abnormal patterns in the visual fields.

Optical Coherence Tomography Analysis is much like Ultra-Sound, except that it uses light instead of sound. This instrument is able to make 3-dimensional images of the Retina. The layers that make up the retina are easily visualized, the location of any abnormalities within the retina can then be identified. Eye conditions, for example Central Serous Retinopathy, Glaucoma may be diagnosed and monitored.

Glaucoma presents in many forms. Most common are open and closed angle Glaucoma. Intraocular Pressure (IOP) in excess of 21mmhg, is a sign that requires close monitoring. Observation of the optic nerves is a must during any eye examination as low IOP can also result in Glaucoma.

The Optos Daytona was designed to assist eye care professionals to diagnose and manage diseases of the retina. It produces a 200 degree image of the retina, wide enough to image almost all of the retina, without the need for dilation.
