Humphrey Visual Field (HVF)
Computerizedcentral to peripheral visual field testing. Diagnostic testing for glaucoma, stroke, diabetes, brain tumor, ptosis, pseudotumor, optic neuritis and many otherdiseases. Usually takes5 to 7 minutes per eye. Sit comfortably(one eye patched at a time) while you press a button each time you see a light appear.
Fluorescein Angiography (FA)
Diagnosticprocedure in which a rapid sequence of photographs are taken to document the blood circulation of the retina and choroid. The dye is usually injected into a vein in the arm, forearm or hand. This procedure takes approximately 20 minutes.
Documentation of retina (posterior segment)
Slit Lamp Photography
Documentation of lid cornea, conjunctiva, lens (anterior segment of the eye)
Optical Coherent Tomography (OCT)
A very mild beam of laserscans through the layers of the retina, making a picture. This helps your physician see exactly what is going on in your eye. Macular swelling, macular holes, macular degeneration, macular puckers and glaucomaare just some of theconditions that enable the doctor to treat and follow the progress of treatment. This procedure takes about 10 minutes. The patient is seated comfortably with their chin and forehead resting while they look into a computeras it scans the retina.
Topographical map of the front surface of the eye shows the doctor how much and where your astigmatism lies. Usually takes 5 minutes.
Optical Coherent Biometry (OCB)
Themost up-to-dateform of measuring eyes for cataract surgery. Instead of ultrasound, this computer uses a mild beam of laser to measure the axial length and corneal measurements.This has its ownprogram for calculating the proper intraocular lens powers. This procedure takes 10 to 30 minutes. If the cataract is very dense, we are able to double-check the measurements with ultrasound. The patient sits in a chair, chin and forehead placed comfortably while several scans are taken of each eye.
One dimensional ultrasoundmeasurements of the eye usedto determine thepowerof intraocular lensimplants thatreplace the natural lens of the eye duringcataract surgery. Procedure takes 20 to 40 minutes. The usual measurements are corneal, white to white,and axial length. These numbers are placed in two or more computer programs that calculate the power of the intraocular lenses for each patient.
Ultrasounduses sound waves that make a picture of the internal structure of the eye. The doctor cansee the presence of retinal detachment, retinal holes, tears, foreign material,hemorrhages, anterior and posterior lesions.Standardized A-scan helps determine the difference in tissue, i.e. malignant melanoma as opposed to metastatic tumors or a benign nevus. This procedure takes about 20 to 40 minutes. Patient is in a comfortable chair while this procedure is performed.
