HA 1Humphrey Automated Visual Field

Your peripheral vision, or side vision, is very important for your visual function, and is also affected by many eye conditions.

Many times, subtle changes in your peripheral vision are not noticed. The Humphrey Automated Visual Field allows us to detect any vision loss that you may not have noticed otherwise.

HA 2This is important for conditions such as Glaucoma, retinal detachments, optic neuritis, retinal blood vessel blockage, brain tumors, ptosis (lid lag), auto-immune conditions like lupus, and many others.

Sitting in front of a concave dome, a computer-driven program flashes small lights at different locations within the dome’s surface, and you press a button when you see the small lights in your peripheral vision. Your responses are compared to age-matched controls to determine the presence of defects within the visual field. The test will detect any loss of peripheral vision and provide a map of that loss which will be helpful in diagnosing the cause.

Normal Results

The peripheral vision is normal in extent.

What Abnormal Results Mean

Abnormal results may indicate diseases or central nervous system problems such as tumors that damage or compress the parts of the brain that deal with vision. Other diseases that may affect the visual field of the eye include diabetes, hyperthyroidism (a condition where the thyroid produces an excess of hormones), hypertension, diseases of the pituitary gland, and multiple sclerosis.

M RTMarco RT 5100 Auto Phoropter

The Marco TRS (Total Refraction System) RT-5100 is the first of its kind in the country.

Replacing the standard refractor, it allows us to control the entire refraction process from a keypad, and move the lenses quickly and accurately without any discomfort to you.

The new technology allows you to spend less time in the exam room, and allows us to get a more accurate refraction.

Your eyes will appreciate the TRS 5100. Refraction is extremely thorough and it decreases the time you need to spend in the chair. A typical, unremarkable refraction, including unaided acuities, subjective refraction, phorias, near testing, and comparison between old and new Rx now averages about 7 minutes. You, the patient, can appreciate the updated technology and actually find more accurate for us to make decisions due to the simultaneous viewing during script refinement.
