Ophthalmology deals with eye diseases and anatomy. An ophthalmologist can perform eye exams and surgery. Ophthalmic instruments are used for diagnosis and surgery, including the ophthalmoscope, fundus camera, and slit lamp. Regular eye exams are important to prevent vision loss.
Ophthalmology is a medical specialty that deals with the eyes, including eye diseases and the anatomy of the eye. A specialist who practices this type of medicine is called an ophthalmologist, and such a specialist can perform eye exams to detect, diagnose, and evaluate various types of eye diseases, and can also correct these conditions through surgery. The term ophthalmic instrument often refers to a diagnostic eye equipment used to examine the eye, such as the tonometer, which measures the pressure within the eye, or the phoropter, which is used to determine the correct prescription for eyeglasses or contact lenses. Ophthalmic instrument may also refer to ocular instruments used during surgery, such as an eye speculum and iris forceps. Common eye diseases that can be detected and evaluated using ophthalmic instruments include retinal detachment, which can lead to vision loss, and glaucoma, which involves damage to the optic nerve.
An ophthalmic instrument used for diagnostic purposes is usually non-invasive. Some instruments shine a bright light into the eye, and sometimes eye drops or other medications are used to dilate the pupil or relax the eye muscles when using a particular eye instrument. In many cases, ophthalmic instruments are part of the regular optometric equipment used during eye exams at an optometrist’s office. A surgical ophthalmic instrument, such as forceps, pliers, or specialized scissors, is usually only used under local or general anesthesia.
A commonly used ophthalmic instrument is the ophthalmoscope. It is used during a regular eye exam and allows the optometrist or ophthalmologist to see the retina at the back of the eye. This is done to check for retinal detachment, as well as other damage to the retina. This ophthalmic instrument is also used to examine the vitreous humor, a jelly-like liquid inside the eyeball, to detect any changes that may cause vision problems. An ophthalmic instrument used for a similar purpose is the fundus camera, which takes photographs of the inside of the eye to monitor or detect eye disease.
Another common ophthalmic instrument is the ophthalmometer, which helps diagnose astigmatism. There is also the slit lamp which is used to examine various external parts of the eye, including the eyelids, iris and white of the eye, and also the internal parts such as the cornea and lens. Certain diseases and conditions, such as metellium diabetes, high blood pressure, and extreme nearsightedness, increase the risk of serious eye disease and subsequent vision loss. Regular eye exams are especially important in these cases to avoid vision loss and blindness.
