The present invention relates generally to an apparatus, and method for treating dry and irritated eye conditions. More specifically, it relates to an apparatus and a method of altering the heat and moisture around the eyes of users to reduce the discomfort of dry eye syndrome and/or burns to the eyes.
Dry eye syndrome is one of the most commonly treated eye problems in the world. Dry eye syndrome is also known as keratitis sicca, keratoconjunctivitis sicca (KCS) xerophthalmia, and lacrimal insufficiency. It is estimated that over thirty million persons worldwide suffer from severe dry eye conditions, e.g., Dry Eye Syndrome or Chronic Dry Eye Disease (CDED), both clinically known as keratoconjuctivitis sicca. CDED is a condition that results from inflammation of the eye, as well as inflammation of the tear-producing glands. This inflammation decreases the eyes' ability to produce natural tears, which help protect the eyes from irritation and keep them moisturized and lubricated. Persons who suffer from CDED often experience constant pain from eye irritation, including a sandy or gritty sensation that, if untreated, can lead to scarring or ulceration of the cornea, which can lead to a partial or total loss of vision.
Dry eye syndrome typically results from deficiency in the quality or quantity of tears produced by the patient. Precorneal tear film of eyes has traditionally been considered to have a three-layered structure. The closest to the cornea lies the mucin, or mucus layer. The mucin layer provides an interface between the corneal epithelium and the remainder of the tear film. Overlying the mucin layer is the watery aqueous layer, which is the thickest layer of the three. The outermost layer of the precorneal tear film is the lipid layer. The lipid layer is an oily film that reduces evaporation from the aqueous layer beneath it. The middle aqueous layer provides moisture to the corneal tissue, carries important nutrients, and serves to remove metabolic waste produced by the cornea. Deficiency in any of the three layers of the precorneal tear film can result in complaints of dry, gritty feeling or burning eyes. The mucin that forms the mucin layer, nearest to the cornea, is secreted by goblet cells in the conjunctiva. The conjunctiva is the transparent tissue that covers the sciera and the backside of the eyelids. The mucin layer functions to decrease surface tension of the tear film. In addition, the cornea itself is hydrophobic. Without the mucin layer to provide a bridge between the cornea and the aqueous layer, the aqueous layer would bead up and allow dry spot formation on the cornea. The aqueous layer is secreted primarily by the glands of Wolfring and Krause located in the eyelid margin. The aqueous layer helps provide an optically smooth, transparent surface to the precorneal tear film. The lipid layer is secreted by the meibomian glands, and the glands of Zeiss and Moll. The glands of Zeiss and Moll are also located at the eyelid margin.
Most cases of CDED result from normal aging of the eye, however, CDED or dry, irritated, tired eyes can occur at any age. It is estimated that nearly 75% of people over the age of 65 will experience CDED conditions. CDED occurs in both men and women, however, it is most common in women who are post-menopausal or pregnant. Approximately 30 million people, of which approximately 90% are women, have CDED as a consequence of Sjδgren's syndrome, which is a chronic, slowly progressive autoimmune disease characterized by dryness of the eyes and mouth and recurrent salivary enlargement. Other diseases, such as rheumatoid arthritis, lupus, scleroderma, and thyroid disease, can also cause CDED. In addition, health, environmental, and lifestyle conditions can also cause CDED. For example, people suffering from allergies and persons, who wear contact lenses, have a greater risk of developing CDED. Other circumstances that significantly dry, irritate, and fatigue the eye include the continuous computer use, low humidity environments, such as flying in an airplane, in which the relative humidity is typically between 5% to 15%, use of certain medications, after eye surgery and due to the usage of certain medical conditions, such as bletharitis i.e. the inflammation of the eyelids.
Blinking is essential to maintenance of the precorneal tear film. During each blink, the eyelid wipes over the surface of the cornea, smoothing the mucin layer and spreading the overlying aqueous and lipid layers to provide a completely wetted surface. In between blinks, the tear film thins due to evaporation of the aqueous layer. If evaporation is excessive, dry spots may form on the surface of the cornea. Deficiency, or imperfect quality, of any of the three component layers can lead to dry eye symptoms. Many systemic and external factors can contribute to dry eye syndrome. For example, Sjogren's syndrome is associated with arthritic diseases in combination with dry eye and dry mouth. Deficiency of Vitamin A, use of oral contraceptives and environmental factors can all contribute to dry eye syndrome. The adnexa of the eye may also be involved in dry eye syndrome. The adnexa of the eye include the structures surrounding the eye such as the eyelids, eyelashes, the tear drainage and tear production structures. Blepharitis commonly contributes to dry eye syndrome. Blepharitis typically results from bacterial infection of the tiny glands in the margin of the eyelid. These glands include the glands of Zeiss, Moll and Wolfring as well as the meibomian glands. Most commonly, the affected glands are the meibomian glands. In bacterial blepharitis, bacterial infection causes the meibomian glands to become plugged, and thus not be able to produce a normal lipid layer to contribute to the tear film. Some bacteria that infect the glands also secrete exotoxins that seep out of the glands into the eye and injure the corneal epithelium.
Treatments of dry eye syndrome vary depending upon the type of presentation. The most common treatment for dry eye syndrome is the use of artificial tear supplements to provide additional moisture and lubrication to the corneal surface. Artificial tear eye drops are placed on the eye by the patient. Artificial tear supplements must be used regularly and often to be effective. In some other cases, lubricant ointments are also be employed. Ointments are usually used at bedtime because they tend to be messy and blur vision. For some patients, even the use of ointments is not sufficient to provide comfort during sleep.
In some instances, one treatment for dry eye syndrome is to partially or completely close one or more lacrimal puncta to reduce tear outflow into the lacrimal drainage apparatus. Traditionally, this closure was accomplished surgically or by cautery. In the last decade, however, temporary and permanent punctal occlusion plugs have been utilized. Permanent punctal plugs are typically made from surgical silicone; temporary plugs are generally made of soluble collagen. Collagen plugs dissolve over a period of days and are helpful in diagnosis. Punctal plugs are placed into the lacrimal puncta, or lacrimal drainage ducts. The plugs impede the outflow of tears from the eye. This approach slows the outflow of tears and retains them in the eyes longer, often relieving symptoms. Punctal plugs have the distinct advantage of being readily removable and avoid the issues of scar formation.
Patients who have severe dry eye syndrome often suffer disrupted sleep because they cannot go for longer than an hour or so without applying tear supplements to the eyes. This can lead to pronounced sleep deprivation and a consequent reduction in quality of life. Different methods as stated above have been employed to treat the dry eye syndrome. For example, U.S. Pat. No. 9,724,230 discloses a method and apparatus for the treatment of dry eye syndrome using adhesive strips that is specifically contoured or shaped to adhere to selected regions around a patient's eyes. Similarly, U. S. Pat. No. 7,186,233 discloses a method for treating dry-eye syndrome includes collecting fluid from inside the eye; and transporting the collected fluid into the fornix of the eyelid such that with each blink, fluid accumulated in the fornix is spread over the eye.
Despite the many treatment options are available, there remains no cure for dry eye syndrome. Many patients still suffer from substantial and even debilitating discomfort because of dry eye syndrome. Very few treatment options exist to provide comfort for dry eye syndrome and burns to the eyes of patients during sleep. Thus there is a need for an apparatus, system and method for treating dry, burns to the eyes and irritated eye conditions.
