Biometry
Biometry is the process of measuring the power of the cornea (keratometry) and the length of the eye, and using this data to determine the ideal intraocular lens power. If this calculation is not performed, or if it is inaccurate, then patients may be left with a significant refractive error.
Fundus Fluorescein Angiography (FFA)
Fundus fluorescein angiography (FFA) is an invasive diagnostic procedure. It helps to assess the anatomy, physiology, and pathology of retinal and choroidal circulation. It aids in the diagnosis of various ocular pathologies. It contributes to decision-making when planning the management of ocular pathology.
Optical Coherence Tomography (OCT)
Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina. With OCT, your ophthalmologist can see each of the retina’s distinctive layers. This allows your ophthalmologist to map and measure their thickness. These measurements help with diagnosis. They also provide treatment guidance for glaucoma and diseases of the retina.
Color Fundus Photography (CFP)
Color Fundus Retinal Photography uses a fundus camera to record color images of the condition of the interior surface of the eye, in order to document the presence of disorders and monitor their change over time.
Visual Field Analysis (VFA)
perimetry test (visual field test) is a method of measuring an individual’s entire scope of vision, that is their central and peripheral (side) vision. Visual field testing actually maps the visual fields of each eye individually. It can help find certain patterns of vision loss. This may mean a certain type of eye disease is present.
It is a good test to find vision loss caused by the eye disease- glaucoma. Regular perimetry tests can be used to see if treatment for glaucoma is preventing further vision loss.
B-Scan/Ultrasound
B-scan ultrasonography is an important adjuvant for the clinical assessment of various ocular and orbital diseases. With understanding of the indications for ultrasonography and proper examination technique, one can gather a vast amount of information not possible with clinical examination alone. This article is designed to describe the principles, techniques, and indications for echographic examination, as well as to provide a general understanding of echographic characteristics of various ocular pathologies.
Biometry
This is a test to measure the shape and size of the eye. It is commonly used to calculate the power of intraocular lens (IOL) implants required for cataract and refractive surgery. Biometry can be performed using either optical coherence interferometry or ultrasound technology.
CCT
Corneal pachymetry is the process of measuring the thickness of the cornea. A pachymeter is a medical device used to measure the thickness of the eye’s cornea. It is used to perform corneal pachymetry prior to refractive surgery, for Keratoconus screening, LRI surgery and is useful in screening for patients suspected of developing glaucoma among other uses.
ECG
An electrocardiogram (ECG or EKG) records the electrical signal from the heart to check for different heart conditions. Electrodes are placed on the chest to record the heart's electrical signals, which cause the heart to beat. The signals are shown as waves on an attached computer monitor or printer.
