OPTOS/RHA Retinal Exam

Dr. Frazee highly recommends Optomap/ RHA retinal screenings because:

  • It allows for enlargement of image to see more detailed view of the retina.

  • RHA provides segmented views 10 layers deep, that a dilated exam cannot

  • It takes just a few minutes start-to-finish, rather than approximately 45 minutes with dilation.

  • You leave the office with vision intact, rather than with light-sensitivity and blur for 4-6 hrs(dilation)

  • Creates a permanent record

  • Allows for future comparisons--we can compare this year’s image to next year’s image—side by side

  • Can be reviewed by other doctors, if necessary for medical conditions or co-management between surgeons

Annual eye exams are vital to maintaining your vision and overall health. Our optometry practice in Richardson, TX offer the optomap® Retinal Exam as an important part of our eye exams. The optomap® Retinal Exam produces an image that is as unique as you fingerprint and provides us with a wide view to look at the health of your retina. The retina is the part of your eye that captures the image of what you are looking at, similar to film in a camera. 

Many eye problems can develop without you knowing. You may not even notice any change in your sight. But, diseases such as macular degeneration, glaucoma, retinal tears or detachments, and other health problems such as diabetes and high blood pressure can be seen with a thorough exam of the retina.  

An optomap® Retinal Exam provides:

  • A scan to show a healthy eye or detect disease.

  • A view of the retina, giving your doctor a more detailed view than he/she can get by other means.

  • The opportunity for you to view and discuss the optomap® image of your eye with your doctor at the time of your exam.

  • A permanent record for your file, which allows us to view your images each year to look for changes.  

The optomap® Retinal Exam is fast, easy, and comfortable for all ages.  To have the exam, you simply look into the device one eye at a time and you will see a comfortable flash of light to let you know the image of your retina has been taken. The optomap® image is shown immediately on a computer screen so we can review it with you.

The RHA™ is a multi-spectral imaging digital ophthalmoscope with a patented optical system that captures high resolution image data through the retinal and subretinal layers. Multi-spectral imaging extends the simple color based analysis eye care professionals use to distinguish between ocular structures. It both expands the examination wavelength range from green to invisible near infrared wavelengths of light and generates the probe wavelengths to separate specific spectral regions for enhanced visibility and discrimination. The combination of the images and extracted data points provides an enhanced view of the retina.


Dilation, the traditional method, requires eye drops that enlarge the pupil area and blurs your near vision for approximately 4 to 6 hours and can cause light sensitivity for that duration. The drops require 30 minutes to take affect and then another 10 to 15 minutes of evaluation with a bright light source and a magnifying lens. The resulting clinical evaluation is similar to the Optomap, if the clinician is experienced, patient is cooperative and pupil dilation is maximized. A comprehensive dilation is achieved through 8 to 10 individual inverted views of each retina that is manually documented on the exam form by your physician.

Retinal imaging and dilation are complementary forms of examination, one does not preclude the other and both forms may be used at the time of examination for the most comprehensive view of the retina.

The RHA’s™ multi-spectral imaging and patented software allow you to benefit from comprehensive high resolution image data sets which highlight key eye health features:

  • Patented multi-spectral imaging creates an extensive set of images and maps highlighting key structures indicative of your retinal and systemic health.

  • The Annidis RHA Report™ presents the image data for detailed and comprehensive analysis by your eye care professional  at the initial and subsequent visits.

  • The images and RHA ReportTM allow the eye care professional to study the data and determine the proper course of action to manage your eye health.

Imagine making your detailed eye health record available to all your health care providers, even if you move from place to place or clinic to clinic. Record portability and standardization means that your record is available if referrals to other health professionals are required.

Visual Evoked Potential

VEP measures the electrical activity in the vision system. When light from an image enters your eye, it is converted into electrical energy at the retina and travels through the optic nerve to the visual cortex of the brain which processes vision. The Diopsys® NOVA-VEP test measures the strength of the signal reaching your visual cortex and how fast it gets there. The VEP technology in the Diopsys® NOVA device helps determine how your eyes communicate with your brain in a way that no other instrument or vision test can.

Pentacam is a simple, painless test to measure multiple parameters of the cornea; including corneal thickness, curvature of the front and back surface of the cornea, anterior chamber depth and various other dimensions of the anterior segment. Common uses of the Pentacam aid in contact lens fitting, refractive surgery, cataracts, and glaucoma.

Cirrus OCT:  "The Standard of Care for the Assessment and Treatment of Most Retinal Diseases"

eye doctor Richardson, TX

The OCT allows for detection of other diseases such as macular holes, hypertensive retinopathy and even optic nerve damage. Using an OCT allows for early treatment in patients and dramatically improves the success of these treatments, especially in diseases such as wet macular degeneration – where the eye disease progresses rapidly.

Humphrey Visual Field

The Field Analyzer is an important tool to detect and follow glaucoma and many other ocular conditions.  Patients who either have glaucoma or are suspected of having glaucoma will undergo repeated testing with this instrument.

The procedure is performed quickly and easily in approximately 15 minutes.  During the test lights of varying intensities appear in different parts of the visual field while the patient’s eye is focused on a central spot.  The results are compared against the normal healthy eye in order to determine if any damage has occurred.
