Ophthalmic Diagnostic & Imaging Services
You and your physicians may benefit from one or more diagnostic studies which are available in our state-of-the art Ophthalmic Diagnostic & Imaging Center.
Comprehensive Dilated Eye Exam
The comprehensive exam includes the following:
Eye & vision health assessment: Our specialists recommend routine annual or biannual eye exams. Family history, previous medical, eye or vision issues and environment are noted. Current symptoms if any, blurry vision, medications along with any other considerations are discussed.
General eye function tests: These include evaluation for depth perception, color vision, light responsiveness, peripheral vision, eye muscle function, focusing, movement, and coordination.
Visual acuity test. Use of eye chart test to measure distance sight.
Visual Field Assessment. Measurement of peripheral vision. Loss of peripheral vision can be a sign of glaucoma.
Dilated eye exam. Drops are used to dilate the pupil to examine the retina and optic nerve. With the use of a special magnifying lens, our specialists inspect the retina and optic nerve for signs of damage and other eye issues.
Tonometry. This is the measurement of internal eye pressure using a tonometer. Numbing eye drops may be used. The tonometer measures pressure inside the eye to detect glaucoma.
Echography: Ultrasound evaluation of the eye and orbit are often helpful in diagnosing and monitoring eye and orbital disorders, including, but not limited to: retinal disease, orbital inflammatory disease, thyroid eye disease, double vision, orbital injuries and orbital tumors.
Pachymetry is an ultrasonic measurement of corneal thickness, which is helpful in monitoring corneal disease or glaucoma.
Gonioscopy is a physician-performed evaluation of the “angle” of the eye, improving assessment and treatment of glaucoma.
Biometry and Lens Calculation with use of the IOLMaster is a technology which has improved surgical planning and accuracy in the selection of lens implant power, in association with cataract surgery.
Fundus photography: High resolution digital photography of the optic nerve and retina for purposes of diagnosis and documentation.
Visual Field Assessment
The visual field refers to the entire area that can be seen when the eyes are focused on a single point. While vision in the middle of the visual field is sharpest, the field of visions extends in all directions.
Blind spots called scotomas indicative of other eye disease can be detected using the visual field assessment. Their shape and characteristics can diagnose issues such as glaucoma, nerve damage or damage to the retina. In addition, neurological conditions such as strokes or tumors are closely linked to the visual field and stroke or tumor location in the brain can often be determined by the size, shape and site of the visual field defect.
Abnormalities in vision or peripheral vision may be detected via visual field analysis. Such abnormalities may be indicative of eye or brain disease. Visual field testing is often requested in screening for or evaluating glaucoma, other optic nerve disorders, retinal disorders or brain disease. We have a variety of techniques and technologies available, which are tailored to your and your physician’s needs, including Goldmann perimetry, Humphrey perimetry and Octopus perimetry. We are one of the few centers in the nation with Goldmann perimetry, which is of particular value in the evaluation and monitoring of neuro-ophthalmic disorders.
Optical Coherence Tomography (OCT)
The retina is made up of distinct layers. Optical coherence tomography (OCT) is a non-invasive imaging test that allows our specialists to map and measure the thickness of each layer to assess the anatomy and health of the optic nerve, retinal nerve fiber layer, retinal ganglion cell layer and macula. OCT has proven to be a valuable tool in the diagnosis and management of both vision disorders and brain disorders. Within the last few years, it has been determined that measurement of the retinal ganglion cell layer is a direct indication of brain health and disease, and it has become a useful adjunct in the monitoring of many brain disorders, even in the absence of visual symptoms.
High Resolution CT
High resolution computerized tomography (CT) scans use X-rays taken from different angles along with computer processing to generate cross-sectional images of the bony eye socket, blood vessels and soft tissues in the eye. CT scans are more comprehensive than X-rays alone. CT scans help diagnose internal injuries from trauma and disease affecting the eye.
The data from CT scans are stored as electronic images that can be viewed on a computer. Our experts are able to review these images and recommend a course of treatment depending on the information gathered during the scan.
- Visualization of muscle or bone issues including bone tumors and fractures
- Detection of internal injuries and internal bleeding
- Detection of tumor, infection or blood clot causing eye condition
- Recommendations for minimally invasive surgery, biopsy or other therapy
- Detection of cancer or other underlying causes of disorder
