Ocular inspection is often applied by people who would want to peruse an object. But in the event that your eyes need assistance by form of eyeglasses, you would first have to undergo a particular procedure before you could lay your hands on your glasses. Since there’s a process, you can at the very least expect some instruments that would serve as sustenance to the procedure. In ophthalmology they have the so called, slit lamps.

Slit lamps and ophthalmology

Basically, a slit lamp is an instrument that consists of a high-quantity light supply especially created to focus in giving luminosity as a breach. It is often used in cahoots with a microscope. The lamps’ function is to expedite for testing procedures as it gazes at the anterior portion or the frontal make-up of the human eye, which composes of the sclera, eyelid, natural crystalline lens, cornea and the conjunctiva.

There exists the ‘binocular slit-lamp examination’ which presents a stereoscopic amplified perspective of the eye make-up in a conspicuous detail, for it enables one to provide concise anatomical analogy which experts use in order to adapt for distinct eye circumstances.

Bunched up with specialized lenses such as the Gonioscopy single-mirror or the Zeiss 4-mirror lens utilized particularly for angle structures, Goldmann 3-mirror lens together with the +90D lens, the +66D lens, the +78D lens and the Hruby (-56D) lenses. With all these lenses working in harmony, the expert would be able to have a fully-detailed observation of the retinal composition.

The slit lamp examination

The procedure in testing and using the slit lamp is a much uncomplicated one. As the patient is requested to sit to undergo this examination, he would be asked by the expert to lay his chin and his forehead on leather padding that supports and keeps the head in a steady position. While using a biomicroscope, the professional would then carry out with the testing of the eye of the patient.

A dainty band of paper that is tainted with fluorescein, which is a dye usually orange in color, would touch the edge of the eye. The stain’s purpose is to break the film on the exterior of the eye so as to be able to help in the examination. In the end the dye is expected to be washed out by the patient’s tears.

The following test would involve the application of drops inside the eye for the purpose of instigating the patient’s eye to dilate. A length of 15 to 20 minutes is the standard time when the eyes should be soaked to the drops. After the process the same procedure is done once again for the intention of examining the back area of the eyes.

At this point the patient is expected to encounter a little bit of light responsiveness and is assumed to last for a couple of hours subsequent to the examination. The drops that have been previously applied may cause the eyes of the patient to experience a boost in pressure on his eyes, which might eventually lead to pain and probably squeamishness.

Though this case is utterly rare, patients’ who are suffering from this condition are recommended to seek medical consideration at once. Adults compared to children don’t need any particular preparation for this examination. It is the children however who are in need for such preparations subject to the child’s age, experiences, level of trust and interests.

Purpose of the slit lamp examination

In medicine, most if not all the examinations are employed so as to diagnose any case of body dysfunction/ the slit exam is often used to determine any ailment in the human eyes which includes: keratonocus, retinal detachment, uveitis, cataract, presbyopia, retinitis pigmentosa, Wilson’s disease, mascular degeneration, Fuchs’ dystrophy and the Retinal vessel occlusion

History of slit lamps

During the early 1900s an astonishing event took place; it is when an ophthalmologist was awarded a Nobel Piece Prize in the field of Medicine. The name of the ophthalmologist was Alvar Gullstrand who is an ophthalmology professor at the University of Uppsala located in Sweden and later on moved to the city of Stockholm.

In his award it is showed that his contribution was included in the discipline of eye dioptrics. Among his principal accomplishment was his creation of the popularly used Gullstrand slit lamp. The slit lamp he created serves as a biomicroscope with exclusive optics as its additional feature, it allows the expert to conduct am itemized microcopic exam of the patient’s eye in a clinical setting.
