Ophthalmic imaging modalities are valuable tools for testing, documentation, and diagnosis of pathological changes in the eye. These modalities quickly provide data that aid physicians and others involved in the treatment process.
A fluorescein angiography is a medical procedure in which a fluorescent dye is injected into the bloodstream. The dye highlights the blood vessels in the back of the eye so they can be photographed. In cases of retinal or choroidal disorders, and in some neuro-ophthalmology cases, fluorescien angiography allows physicians to see normal and abnormal patterns of blood flow to the eye, often providing critical that allow physician to determine the diagnosis.
Optical Coherence Tomography (OCT):
This is a scanning laser procedure) that takes high-resolution images of the structures of the eye. It can provide documentation of the presence of fluid in the retina, swelling of the optic nerve and retinal nerve fiber density for tracking the course of glaucoma, verifying efficacy of treatment. OCT can also help in the diagnosis and management of certain forms of glaucoma and many other anterior segment diseases.
The photography service at the Cizik Eye Clinic also provides fundus photography, which records digital images of the retina; slit-lamp photography, which offers images of the cornea, iris, and lens; and external photography to record unbalanced muscles, malpositioned eyelids, traumatic injuries, and configuration of orbits.
The Ultrasonography unit at the Cizik Eye Clinic provides noninvasive diagnostic testing and evaluations of adults and children. Ultrasonography permits identification of ocular and orbital lesions such as tumors, retinal detachments, hemorrhages, or foreign bodies within the eye that cannot be detected by conventional examination procedure.
Confocal microscopy is a noninvasive technique that permits in vivo visualization of the entire corneal thickness. The precise measurements that are possible with this technique permit localization of intracorneal disease processes.
