An eye doctor is a person who offers a medical service related to vision or the eyes. In simple terms, it is any health care worker engaged in eye health care, from one having a very limited amount of formal post-secondary education to highly trained practitioners with a Ph.D. degree. Eye doctors usually perform diagnostic and treatment roles for their patients and have an expertise in treating various eye diseases. Here are some basic job descriptions of eye doctors that will help you understand the breadth of this eye-care field.
An eye doctor might diagnose a patient's eye problems with the help of a variety of visual field testing procedures like the refraction assessment. This refers to detecting irregularities in the patient's vision through eye-exams or with the help of specialized instruments like ophthalmoscopes and glasses. Refraction affects the natural curvature of the eye and develops as a person grows older. A person can experience any vision loss according to the degree of its severity.
The visual field diagnose is used to detect any abnormalities in the patient's vision and thus helps the eye doctor to provide suitable treatment. The patient's eyes undergo a complete examination under the eye doctor's supervision, including comprehensive laboratory tests to measure and isolate the cause of any dysfunction. These include complete blood count, a complete eye examination, laboratory tests for viral, bacterial and fungal infections and tests for underlying diseases such as diabetes, hypertension and family medical history. For severe cases, patients are treated with artificial intraocular pressure, or IOP, which is a pump applied to the eye to correct the internal pressure within the eye and prevent optic nerve damage.
Another important service that an eye doctor performs is the routine retinal examination. This is the exam that is done on every patient to determine the eye disease and monitor the health of the retina. The eye doctor uses various techniques to perform the exam, such as Computerized Tomography (CT) Scanning, Fluorescent Scintillation, and Venopacity Anomaly Screening. All these methods use a laser or other high-tech tools to examine the retina. Depending on the type of exam required, a certain amount of preparation is needed before the actual exam takes place.
Many times, eye doctors may use eye drops to perform the exam. This product contain the dye for assessing the eye disease, along with other chemicals for removing or neutralizing harmful bacteria or irritants, if present. Eye drops should always be prescribed by your ophthalmologist. If you have any allergies or other medical condition, it is best not to administer medicine through eye drops. If eye drops are administered, make sure to contact your doctor immediately.
Some ophthalmologists also recommend or prescribe reading glasses or contact lenses for some patients. These glasses or contacts can be used to help correct a patient's vision, as well as to enhance their facial features, since glasses or contacts might block some rays of light from entering the eyes. These are generally worn while the patient sleeps. If the eye doctor thinks that a patient might benefit from either glasses or contacts, he or she will usually let them know about their options and recommend the best option.
