1. Ocular Biomicroscopy
This imaging test includes the use of a digital ocular biomicroscope to inspect eye structures like the lids, lashes, conjunctiva, sclera, cornea, iris, and lens for possible diseases like conjunctivitis, cataract, stye, and other eye diseases.
2. Retinal Photography
This imaging test includes the use of a retinal photographer to evaluate the optic disc, macula, and retinal blood vessels for diseases like retinal detachments, diabetic or hypertensive eye disease, glaucoma, macular degeneration, and other internal eye diseases.
3. Corneal Topography
Corneal topography is a special imaging technique that maps the surface of the cornea, the clear outermost covering of the eye. It works much like a 3D (three-dimensional) map that helps visualize the curvature of the cornea. It is a useful guide to help determine appropriate management for individuals with high astigmatism and corneal diseases like keratoconus, keratoglobus, keratomalacia, etc.
4. Dry eye screening
Dry eye screening is used to assess the presence of keratoconjunctivitis sicca (dry eyes). Dry eyes occur when the tear glands do not function properly, due to age, certain diseases, medications, low humidity, and dusty environment. Untreated dry eyes can lead to eye infections, eye inflammations, corneal scarring, corneal ulcers, and vision loss.
5. Glaucoma Screening
Ocular biomicroscopy is used to determine the depth of the iridocorneal angle. Individuals with shallow iridocorneal angles are prone to develop closed angle glaucoma.
Tonometry test is used to measure the pressure inside the eyes. Individuals with high intraocular pressure are prone to develop glaucoma if not managed early.
6. Cornea, Lens, and Vitreous Opacities Screening
Retro-illumination imaging is used to assess the presence of foreign bodies in the cornea, corneal dystrophies, corneal edema, and corneal scars. It is also used to assess the location and severity of cataracts, especially cortical and subcapsular cataracts, as well as opacities in the vitreous gel of the eye.
