  • Excisional Biopsies

    Dr. Jolly uses a small blade (scalpel) to remove an entire lump, an area of abnormal skin, or growth including a portion of normal skin down to or through the fatty layer of skin.  We perform biopsies on lesions, neoplasms, growths and abnormal looking skin areas on the eyelids, conjunctiva and other skin areas around the eye.

  • Pterygium Excision

    Pterygium is a common condition that often affects people who spend a lot of time outdoors.  People with pterygium have a growth of pink, fleshy tissue on the white of the eye. The growth usually forms on the side closest to the nose and grows toward the center of the eye. Pterygium is a noncancerous lesion that usually grows slowly throughout life. It may even stop growing after a certain point. In advanced cases, a pterygium can continue growing until it covers the pupil of the eye and interferes with vision. Dr. Jolly performs an in-office procedure to remove this tissue and uses a conjunctival autograft.  Conjunctival auto-grafting is a surgical technique that is effective and safe procedure for pterygium removal. When the pterygium is removed, the tissue that covers the sclera known as the conjunctiva is also extracted. Auto-grafting replaces the bare sclera with healthy conjunctival tissue that is surgically removed from another part of the eye. That “self-tissue” is then transplanted to the bare sclera and is fixated using glue adhesive.  This helps decrease any pain associated with the procedure and prevents a recurrence of the condition.

  • Fluorescein Angiography

    Intravenous Fluorescein angiography (IVFA) or Fluorescent Angiography (FAG) is a technique for examining the circulation of the retina and choroid using a fluorescent dye and a specialized camera. It involves injection of sodium fluorescein into the systemic circulation, and then an angiogram is obtained by photographing the fluorescence emitted after illumination of the retina with blue light at a wavelength of 490 nanometers. The test uses the dye tracing method.

    The fluorescein dye also reappears in the patient urine, causing the urine to appear darker, and sometimes orange. It can also cause discolouration of the saliva. Fluorescein angiography is one of several health care applications of this dye, all of which have a risk of severe adverse effects. However, fluorescein angiography does not involve the use of ionizing radiation.

  • Optic Disc Photography

    This is photography of the Optic Nerve. The most common use of the Optic Disc Photography is when a patient has a form of Glaucoma. Glaucoma is a disease that damages the Optic Nerve by an increase of the Intraocular Pressure (IOP). Most commonly, elevated IOP is due to not being able to circulate the fluid throughout the eye. As pressure builds, it pushes back on the Optic Nerve and damages the fibers of the Optic Nerve. This causes your peripheral vision to start to deteriorate and can ultimately causing blindness.

    Once the Optic Nerve is damaged by Glaucoma you can never regain your vision. It’s very important to get a check up at least once a year with either an Optometrist or Ophthalmologist because if you start to have Glaucoma, you don’t feel anything. Even though your Intraocular Pressure (IOP) might be high and damaging your optic nerve, you won’t be able to tell or feel any difference – unless the pressure builds up to a dangerous level (>40mmHg) in which case you may experience symptoms of severe headaches, nausea, and vomiting. (The common IOP is usually below 20mmHg.) 

  • Ophthalmic Ultrasound

    A-scan ultrasound biometry, commonly referred to as an A-scan, is routine type of diagnostic test used in ophthalmology. The A-scan provides data on the length of the eye, which is a major determinant in common sight disorders.

  • Corneal Topography

    A non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye’s refractive power, its topography is of critical importance in determining the quality of vision and corneal health.

    The three-dimensional map is therefore a valuable aid to the examining ophthalmologist or optometrist and can assist in the diagnosis and treatment of a number of conditions; in planning cataract surgery and intraocular lens (IOL) implantation (plano or toric IOLs); in planning refractive surgery such as LASIK, and evaluating its results; or in assessing the fit of contact lenses. A development of keratoscopy, corneal topography extends the measurement range from the four points a few millimeters apart that is offered by keratometry to a grid of thousands of points covering the entire cornea. The procedure is carried out in seconds and is completely painless.

  • Optical Coherence Tomography

    Retinal imaging uses special cameras and scanners to make magnified images, or pictures, of the back of your eye. This includes the retina. It’s the part of the eye that’s most responsible for your vision.

    Common imaging methods include:

    • Color and black-and-white photography. A camera magnifies the back of your eye and makes pictures.
    • Optical coherence tomography, or OCT. A scanner uses light waves to form an image of the retina on a computer screen.
    • Ultrasound. This test uses sound waves to form the image.
    • Angiogram. A dye is injected into your arm. It flows through your blood to the blood vessels in your eye. The dye makes the blood vessels in your eye easier to see as your doctor looks at your eyes through the camera.

    A test called fundus autofluorescence is sometimes used. Special lighting lets the doctor see microscopic changes in your eye that are caused by certain conditions.

  • Visual Field Testing

    A perimetry test (visual field test) measures all areas of your eyesight, including your side, or peripheral, vision.

    To do the test, you sit and look inside a bowl-shaped instrument called a perimeter. While you stare at the center of the bowl, lights flash. You press a button each time you see a flash. A computer records the spot of each flash and if you pressed the button when the light flashed in that spot.

    At the end of the test, a printout shows if there are areas of your vision where you did not see the flashes of light. These are areas of vision loss. Loss of peripheral vision is often an early sign of glaucoma.

  • Eyelid Surgery


    Blepharoplasty, commonly called an “eyelid lift”  includes surgery to repair droopy eyelids that may involve removing excess skin, muscle and fat.

    As you age, your eyelids stretch, and the muscles supporting them weaken. As a result, excess fat may gather above and below your eyelids, causing sagging eyebrows, droopy upper lids and bags under your eyes.  Severe sagging skin around your eyes can reduce your side vision (peripheral vision), especially the upper and outer parts of your field of vision. Blepharoplasty can reduce or eliminate these vision problems.

    Blepharoplasty is usually done in our office or at an outpatient facility.  To help decide if blepharoplasty is right for you, find out what you can realistically expect and explore the benefits and risks of blepharoplasty.

    Ectropion Repair

    Ectropion is a condition in which your eyelid — typically the lower lid — turns out. This leaves the inner eyelid surface exposed and prone to irritation. Ectropion is more common in older adults.

    In severe ectropion, the entire length of the eyelid is turned out. When ectropion is less severe, only one segment of the eyelid sags away from the eye.

    Artificial tears and lubricating ointments can help relieve the symptoms caused by ectropion until you can have surgery to correct the condition.

    Entropion Repair

    Entropion is a condition in which your eyelid turns inward so that your eyelashes and skin rub against the eye surface, causing irritation and discomfort.

    When you have entropion, your eyelid may be turned in all the time or it may only turn inward when you blink forcibly or tightly squeeze your eyelids shut. Entropion occurs most often in older adults, and it generally affects only your lower eyelid.

    Artificial tears and lubricating ointments can help relieve symptoms of entropion, but you’ll often need surgery to correct it. Left untreated, entropion can cause damage to the clear part of your eye (cornea) and lead to eye infections and vision loss.

  • Contact Lens Fittings

    Contact lenses are small plastic or silicone discs shaped to correct refractive errors. After your doctor tests your vision, he or she will write a prescription for the lens you need. Your prescription may change over time.

    Contacts are placed directly on the eye, where they float on a film of tears in front of the cornea. Correct design and fitting of the lenses are essential for comfort, safety, and accurate correction.

    Improvements in contact lenses have made them more comfortable and easier to wear. Millions of people wear contact lenses, and most wear soft lenses. For these people, contact lenses offer a relatively safe and effective way of correcting vision problems.

Additional Definitions

  • Dry Eye

    Dry eyes occur when the eyes do not produce enough tears to lubricate the eye. Symptoms include pain, itching, redness, blurry vision, and more. Causes may include aging, medication side effects, diseases, and eye structure problems. Treatments involve eyedrops, punctal occlusions, medications, and/or surgery.

  • Glaucoma

    glaucoma developmentGlaucoma is the name for a group of eye diseases that damage the optic nerve. This nerve carries information from the eye to the brain. When the nerve is damaged, you can lose your vision.

    Glaucoma is one of the most common causes of legal blindness in the world. At first, people with glaucoma lose side (peripheral) vision. But if the disease isn’t treated, vision loss may get worse. This can lead to total blindness over time.

    There are three types of glaucoma.

    • Open-angle glaucoma (OAG) is the most common form in the United States and Canada. (In other parts of the world, it’s less common.) It usually affects both eyes at the same time. Your vision gradually gets worse. But it gets worse so slowly that you may not notice it.
    • Closed-angle glaucoma (CAG) isn’t very common in the U.S. and Canada. It usually affects one eye at time. CAG can happen suddenly and be a medical emergency.
    • Congenital glaucoma is a rare form of glaucoma that some infants have at birth. Some children and young adults can also get a type of the disease.

    The exact cause isn’t known. Experts think that increased pressure in the eye (intraocular pressure) may cause the nerve damage in many cases. But some people who have glaucoma have normal eye pressure.

  • Diabetic Eye Disease

    diabetic eye diseaseAs our population ages, vision loss from eye diseases is increasing.

    According to the National Eye Institute (NEI):

    • About 3.3 million Americans aged 40 or older are blind or have low vision. This is about 1 in every 28 people.
    • By 2020, that number could be 5.5 million — a 60% increase.

    NEI has identified the most common eye diseases in people over age 40 as:

    • Age-related macular degeneration
    • Cataracts
    • Diabetic eye disease
    • Glaucoma

    To catch eye conditions early and help prevent vision loss, your doctor may recommend an eye exam every two years or more often after age 60, or if you are at high risk for an eye problem.

  • Macular Degeneration

    macular degenerationMacular degeneration (AMD) is caused by deterioration of the retina and can severely impair vision. There is no cure for macular degeneration, but it can be treated with vitamins, laser therapy, medications, and vision aids.

    Your Eyes and Age-Related Macular Degeneration

    Age-related macular degeneration (AMD) damages, then destroys, central vision, your “straight-ahead,” finely detailed vision. This eye disease takes two forms, dry and wet. About 90% of AMD cases are dry. The remaining 10% are wet, a more advanced form. Wet AMD is more damaging, causing about 90% of serious vision loss.
