Slit Lamp is a stereoscopic biomicroscope that emits a focused beam of light with variable height, width and angle. This unique instrument allows the three-dimensional display of the delicate anatomy of the parts and the anterior part of the eye. With the help of a special hand-held lens, the examiner can also see the posterior part of the eye. With the use of an angular contact lens, the iridocorneal angle can be examined as well.

The Slit Lamp is therefore the mainstay of the integrated ophthalmological examination, allowing ophthalmologists to evaluate each anatomical compartment of the eye. Although the knowledge of the Slit Lamp requires time and experience, its basic use for the treatment of common eye complaints is a useful qualification for medical students as well as physicians.

Slit Lamp: what can be examined?

  1. Periopthalmic area and Orbit: Can be evaluated for defects such as basal cell carcinoma or squamus cell carcinoma.
  2. Eyelids and Eyelashes: Among conditions that can be diagnosed are chalazion, hordeolum, trichiasis, etc.
  3. Conjunctiva and Sclera: The tiny vessels of the Conjunctiva, the Sclera and the Episclera can be examined with appropriate lighting and angle of the beam to differentiate diseases such as episcleritis, scleritis and conjunctivitis.
  4. Cornea: A thorough examination of the Cornea involves a slow scan from the temple to the nasal portion across the entire surface, at low magnification, noting any abnormalities in the thickness or transparency of the Cornea, localization of endothelial sediments, epithelial abrasions, dendritic ulcers and a plethora of other pathologies related to infectious systemic and autoimmune causes.
  5. Iris: Nevi and neovascularization of the Iris, which is a sign of advanced ocular pathology, can be examined.
  6. Crystalline Lens: Blurring and pathology of the Lens lead to vision loss, especially in older people (Cataracts), but the clarity of the Lens can also be altered by systemic disease or chronic cortisone intake.

Slit Lamp – Fundoscopy: What is it and why is it important

Fundoscopy, especially when the pupils are dilated for a more complete view of the entire retina, allows for examination of the retina to help diagnose conditions and identify risk factors for potential vision loss associated with the retina.

For example, patients with diabetes should have an annual dilated fundus examination to check the retina for signs of diabetic retinopathy that could lead to permanent or difficult-to-treat vision loss.

Signs of diabetic retinopathy, which is often a sign also of systemic disease associated with diabetes, include bleeding, inflammation, lack of oxygen, and other problems with the retina that can lead to permanent vision loss.

Fundoscopy can help diagnose a variety of other diseases, such as diagnosing ocular inflammations and infections that require treatment to maintain vision, but also diagnoses inherited dystrophies, such as Stargardt Disease and Retinitis Pigmentosa. Fundoscopy plays an equally important role in the diagnosis of Age-Related Macular Degeneration, in combination with Optical Coherence Tomography (O.C.T.).

Orasis Acupuncture Institute

The Orasis Acupuncture Institute is equipped with a Visual Field machine. The relevant ophthalmological examinations are performed by the Ophthalmologist – Acupuncturist of the Institute.

The action of acupuncture, based on existing data and operated by a qualified Doctor – Acupuncturist, may improve the microcirculation that supplies the optic nerve, resulting in some possible small improvement in the patient’s visual field.
