Vitrectomy0

pars_plana_vitrectomyVitrectomy is the surgical removal of the vitreous gel from the middle of the eye . It may be done when there is a retinal detachment, because removing the vitreous gel gives your eye doctor (ophthalmologist) better access to the back of the eye. The vitreous gel may also be removed if blood in the vitreous gel (vitreous hemorrhage) does not clear on its own.

During a vitrectomy, the surgeon inserts small instruments into the eye, cuts the vitreous gel, and suctions it out. After removing the vitreous gel, the surgeon may treat the retina with a laser (photocoagulation), cut or remove fibrous or scar tissue from the retina, flatten areas where the retina has become detached, or repair tears or holes in the retina or macula.

At the end of the surgery, silicone oil or a gas is injected into ...

Vision Tests0

Vision TestVision tests check many different functions of the eye. The tests measure your ability to see details at near and far distances, check for gaps or defects in your field of vision, and evaluate your ability to see different colors.

  • Visual acuity tests are the most common tests used to evaluate eyesight. They measure the eye’s ability to see details at near and far distances. The tests usually involve reading letters or looking at symbols of different sizes on an eye chart. Usually, each eye is tested by itself. And then both eyes may be tested together, with and without corrective lenses (if you wear them). Several types of visual acuity tests may be used.
  • Refraction is a test that measures the eyes’ need for corrective lenses (refractive error)...

Visual Field Test0

visual_field_test GlauWhat is a visual field test?

A visual field test is a method of measuring an individual’s entire scope of vision, that is their central and peripheral (side) vision. Visual field testing actually maps the visual fields of each eye individually. The visual field test is a subjective examination, requiring the patient to understand the testing instructions, fully cooperate, and complete the entire test in order to provide useful information.

What is a visual field test used for?

Visual field testing is most frequently used to detect any signs of glaucoma damage to the optic nerve...

Optical Coherence Tomography0

OCT 2What Is Optical Coherence Tomography?

Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-section pictures of your retina, the light-sensitive tissue lining the back of the eye.

Optical coherence tomography (OCT) is an imaging modality analogous to ultrasound, but instead of using the difference in the flight times of acoustic waves (as in ultrasound), it uses light to achieve micrometer axial resolution. OCT is used in many different biomedical applications, with retinal imaging being the most successful and the driving force behind much OCT development. The axial resolution of OCT in retinal tissue is about 1-15 ┬Ám, which is 10 to 100 times better than ultrasound or MRI...

Fluorescein Angiography0

FAWhat Is Fluorescein Angiography?

Fluorescein angiography is a medical procedure used in the diagnosis of retinal problems. A dye is introduced into the bloodstream. When the dye reaches the blood vessels in the eye a series of flash photographs are taken.

An eye angiogram uses fluorescein dye and a camera to take pictures and evaluate the blood flow through the vessels in the back of the eye (retina).

During an eye angiogram, the dye is injected into a vein in your arm. Once injected, it takes about 10 to 15 seconds to circulate through your body. As the dye enters the blood vessels in your eyes, a series of photos are taken to chart the dye’s progress. More pictures are taken after most of the dye has passed through your eyes to see if any of it has leaked out of the blood vessels...

Cyclorefraction0

cycloA cycloplegic refraction is a procedure used to determine a person’s refractive error by temporarily paralyzing the muscles that aid in focusing the eye. Cycloplegic eye drops are used to temporarily paralyze or relax the cililary body, or focusing muscle, of the eyes.

Cycloplegic refraction is sometimes used when testing the vision of young children. Children sometimes subconsciously accommodate their eyes during an eye exam, making the results invalid.

A cycloplegic refraction is also performed as part of a laser vision correction or LASIK consultation to determine the absolute refractive error before proceeding with laser eye surgery.

Why child need cycloplegic refraction?

Because of the high level of accommodative activity found in many children, the cylinder power measured during reti...

Cornea Transplant0

Corneal TransplantA cornea transplant is a surgical procedure to replace part of your cornea with corneal tissue from a donor. Your cornea is the transparent, dome-shaped surface of your eye that accounts for a large part of your eye’s focusing power.

A cornea transplant can restore vision, reduce pain and improve the appearance of a damaged or diseased cornea. A cornea transplant, also called keratoplasty, is typically performed as an outpatient procedure.

Most cornea transplant procedures are successful. But cornea transplant carries a small risk of complications, such as rejection of the donor cornea.

A cornea transplant is most often used to restore vision to a person who has a damaged cornea. A cornea transplant may also relieve pain or other signs and symptoms associated with diseases of the cornea.
