Visual Field Analysis

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

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.

Cerium Precision Tinted Lenses

Have you ever looked at a pattern for example on a carpet and the pattern seems to be doing strange things like vibrating or seems to be moving. To some, Lines of text on a page can produce a similar illusion. . Patients describe he text as moving, lines going through the text,. reading is more comfortable in low light,. Even headaches have been reported. This results in slow readers as the illusion is distracting. This is call perceptual distortion.

Glaucoma

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.

Wide Field Retinal Imaging

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.

What is Orthokeratology?

Simply speaking, this is a contact lens that you wear so you do not have to wear contact lenses — During your waking hours that is . Confused, well let me be more clear. This is a night time lens, worn overnight, it gently molds the shape of your cornea, causing it to flatten, thus changing the refractive state of your eyes. This flattening is similar to the flattening done with a laser in a procedure called Lasik.
