Dry Eye Disease

Dry Eye Disease (DED)

This condition may also be known as Ocular Surface Disease (OSD). Many people, whether they are aware of it or not, suffer from dry eyes.  Dry eye syndrome (DES) is one of the most common yet most under diagnosed conditions affecting the health of the eye.  The complex nature of dry eye can begin as young as 10 or 11 years old and continues  throughout a patient’s life.

Dry eye syndrome causes more than just discomfort; it can result in permanent damage to the cornea, vision loss, and other problems.  It can also be a symptom of an underlying medical condition.  For these reasons and more, we take dry eye very seriously and you should too.

Types of Dry Eye Syndrome

Tears are comprised of 3 layers: lipid (oil), water and mucus.  The composition of these components is what helps to protect and nourish the surface of our eyes.  The lipid or oil layer prevents the evaporation of the water layer.  The mucus layer helps spread the tears evenly over the eye surface.  When these layers are not functioning properly, the tears can either evaporate too rapidly or they do not reach the entire eye surface, which will then case the symptoms of dry eyes.

There are two predominant forms of dry eye, aqueous and evaporative.

Aqueous Dry Eye

Aqueous dry eye is characterized by tear deficiency.  It occurs when the lacrimal, or water producing glands don’t produce enough of the watery component of tears.  Patients with aqueous dry eye are normally good candidates for Restasis®.

Evaporative Dry Eye

Evaporative dry eye affects 85% of dry eye patients.  It is caused by Meibomian gland dysfunction (MGD), which creates a deficiency in the oil layer of the tear film.  These glands make the lipid or oily part of tears that slows evaporation and keeps the tears stable.  This can be the beginning of other dry eye disease problems including damage to the cornea and sight-related issues.

Diagnosing Dry Eye Syndrome

Dry eye symptoms can be very subtle, patients often go under diagnosed or under treated.  At Center For Sight, we utilize a multi-faceted approach to diagnosing dry eye syndrome.  We combine patient self-assessment, physician administered testing and state-of-the art diagnostic technology to determine the cause, severity and best treatment protocol for each patient’s dry eye condition.  Your diagnostic process may include:

  • SPEED™ Dry Eye Questionnaire
  • Osmolarity Testing (Tear Lab)
  • Lipid Layer Testing (Lipid View)
  • Blinking Pattern Evaluations (LipiView)
  • In-Office testing for Sjogren’s syndrome, if indicated
  • InflammaDry® Testing

Dry Eye Treatment

Dry Eye is more than an inconvenience. Dry Eye is a disease.

Many people suffer for years from the discomfort and pain of Dry Eye Disease Most try various products to manage their disease, and while many of the Over-The-Counter products can provide relief, it is just temporary symptom relief.

Meibomian Gland Dysfunction (MGD) is a leading cause of Dry Eye Disease.1 Dry Eye Disease is rarely due to a lack of the watery part of your tears. 86% of dry eye patients have MGD.2

What is Meibomian Gland Disfunction (MGD)?

Meibomian Gland Dysfunction is a progressive disease of the ocular surface. Long term, failure to treat MGD can lead to chronic discomfort and degradation of vision, significantly impacting quality of life.3

Healthy Meibomian glands that line your upper and lower eyelids secrete oil with every blink. Your Meibomian glands produce the oily part of the tear film needed to protect the surface of your eye by preventing the evaporation of the watery part of your tears. When this function is not working well, your eyes may feel dry. Keeping the function and structure of your Meibomian glands healthy before you become symptomatic is key, as MGD progresses over time.

MDG Oil Secretion comparison

What causes MGD?

MGD is caused by anatomical changes in the Meibomian glands If left untreated, MGD can become progressively worse over time.

Conditions that can contribute to MGD:

Indications and important safety information for TearScience® LipiFlow® Thermal Pulsation System

Caution: Federal USA law restricts this device to sale by or on the order of a physician.

Indications: The TearScience® LipiFlow® Thermal Pulsation System is intended for the application of localized heat and pressure therapy in adult patients with chronic cystic conditions of the eyelids, including meibomian gland dysfunction (MGD), also known as evaporative dry eye or lipid deficiency dry eye.

Contraindications: Do not use the TearScience® LipiFlow® System in patients with the following conditions. Use of the device in patients with these conditions may cause injury. Safety and effectiveness of the device have not been studied in patients with these conditions. Ocular surgery within prior 3 months, including intraocular, oculo-plastic, corneal or refractive surgery procedure. Ocular injury within prior 3 months. Ocular herpes of eye or eyelid within prior 3 months. Active ocular infection (e.g., viral, bacterial, mycobacterial, protozoan, or fungal infection of the cornea, conjunctiva, lacrimal gland, lacrimal sac, or eyelids including a hordeolum or stye). Active ocular inflammation or history of chronic, recurrent ocular inflammation within prior 3 months (e.g., retinitis, macular inflammation, choroiditis, uveitis, iritis, scleritis, episcleritis, keratitis). Eyelid abnormalities that affect lid function (e.g., entropion, ectropion, tumor, edema, blepharospasm, lagophthalmos, severe trichiasis, severe ptosis). Ocular surface abnormality that may compromise corneal integrity (e.g., prior chemical burn, recurrent corneal erosion, corneal epithelial defect, Grade 3 corneal fluorescein staining, or map dot fingerprint dystrophy).

Precautions: The Activator or Activator II (Disposable) may not fit all eyes, such as eyes with small palpebral fornices. Use of the TearScience® LipiFlow® System in patients with the following conditions may result in reduced treatment effectiveness because these conditions may cause ocular symptoms unrelated to cystic meibomian glands and require other medical management. Safety and effectiveness of the device have not been studied in patients with these conditions. Moderate to severe (Grade 2-4) allergic, vernal or giant papillary conjunctivitis. Severe (Grade 3 or 4) eyelid inflammation (e.g., blepharochalasis, staphylococcal blepharitis or seborrheic blepharitis). Patients with severe eyelid inflammation should be treated medically prior to device use. Systemic disease conditions that cause dry eye (e.g., Stevens-Johnson syndrome, vitamin A deficiency, rheumatoid arthritis, Wegener’s granulomatosis, sarcoidosis, leukemia, Riley-Day syndrome, systemic lupus erythematosus, Sjögren’s syndrome). Taking medications known to cause dryness (e.g., isotretinoin (Accutane®) and systemic antihistamines). Esthetic eyelid and eyelash procedures (e.g., blepharoplasty, lash extensions, eyelid tattooing). In addition, the treatment procedure may loosen previously inserted punctal plugs, which may worsen the patient’s dry eye symptoms.

Adverse Effects: Potential adverse effects that may occur as a result of the procedure include, but are not limited to, the onset or increase in: Eyelid/eye pain requiring discontinuation of the treatment procedure; Eyelid irritation or inflammation (e.g., edema, bruising, blood blister, dermatitis, hordeolum or chalazion); Ocular surface irritation or inflammation (e.g., corneal abrasion, conjunctival edema or conjunctival injection (hyperemia)); and Ocular symptoms (e.g., burning, stinging, tearing, itching, discharge, redness, foreign body sensation, visual disturbance, sensitivity to light). Potential serious adverse events (defined as permanent impairment or damage to a body structure or function or necessitates medical or surgical intervention to preclude permanent impairment or damage to a body structure or function) that are not anticipated because of the device mitigations to prevent occurrence include: Thermal injury to the eyelid or eye, including conjunctiva, cornea or lens; Physical pressure-induced injury to the eyelid; and Ocular surface (corneal) infection.

ATTENTION: Reference the TearScience® LipiFlow® Thermal Pulsation System Instructions for Use for a complete listing of indications, warnings, and precautions.
