Problems solved by technology

Blepharitis, an inflammation of the edge of the eyelid, is a common clinical problem.
However, even invasive treatments such as surgery often result in no significant improvement, and/or a recurrence of the demodex infestation.
The demodex mite burrows into hair follicles and sebaceous glands of the animal, the mite often causing severe dermatitis, infection, and discomfort.
Demodetic mange, particularly in dogs, presents a difficult clinical problem for veterinarians, as it can involve the face and the entire body of the animal in some cases.
Existing treatments can be expensive and are not al

case example no.1

Case Example No. 1

[0141]A 68 year-old female complained of foreign body sensation, redness and itching in the left eye for 2 years. On Feb. 4, 2004, she received surgery to remove primary pterygium and reconstruction with amniotic membrane transplantation. The pterygium recurred on May 4, 2004, and she received another pterygium removal and reconstruction with conjunctival autograft from the right eye. Nevertheless, the pterygium recurred shortly afterwards, and she was referred to Ocular Surface Center for being considered for re-operation for her multi-recurrent pterygium (FIG. 6A). On Jul. 7, 2004, besides recurrent pterygium, she was found to have meibomian gland dysfunction, conjunctivochalasis, and aqueous tear and lipid tear deficiency dry eye. Furthermore, her lashes were loaded with diffuse cylindrical dandruff (CD) (FIG. 6B). The diagnosis of ocular demodicosis was made because of a high demodex count of 19 per 8 lashes (i.e., 19 demodex mites found in a total of 8 lashes ...

Case Example No. 2

[0144]An 81 year-old male complained of dryness in the left eye worse than the right eye and chronic irritation for the past 4 years. His left eye received 6 times of glaucoma drainage implant surgeries for primary open angle glaucoma. On Nov. 11, 2002, he was referred to Ocular Surface Center and was found to have exposure keratopathy due to ectropion, misdirected lashes, cicatricial keratoconjunctivitis (thought to be due to old trachoma), meibomian gland dysfunction with lipid tear deficient (LTD) dry eye, and delayed tear clearance in both eyes. His conjunctiva was inflamed. His left eye was treated with non-preserved 1% methylprednisolone drops, and then with symblepharonlysis, formix reconstruction, intraoperative application of mitomycin C, and amniotic membrane transplantation on Jan. 17, 2003. He also received subconjunctival injection of long-acting steroid (Keralog®) in the left eye on Jan. 7, 2003 and horizontal lid tightening of both lower lids on May ...

Case Example No. 3

[0146]A 55 year-old female complained of foreign body sensation and irritation in the left eye worse than the right eye for 5 years. She received bilateral upper lid blepharoplasty in 1998, and surgical excision of conjunctival cysts for 3 times, epilation of trichiasis, and insertion of punctual plugs in 2002. Because of persistent foreign body sensation and chronic irritation, she was referred to Ocular Surface Center and found on Jul. 17, 2002 to have trichiasis (2 on the left upper lid), meibomian gland dysfunction, and lipid tear deficient dry eye. She received 0.2% non-preserved dexamethasone eye drops, epilation, subconjunctival injection of long-acting steroid (KERALOG®). On Aug. 12, 2004, she received excision of conjunctivochalasis and reconstruction with amniotic membrane transplantation in the left eye, and wore a bandage contact lens postoperatively. Despite these treatments, she continued to complain of these symptoms. On Nov. 15, 2004, her lashes wer...

Abstract

The present invention relates to a method for treating a disorder chosen from ocular Demodex, Demodex-induced blepharitis, rosacea, acne, and meibomian gland dysfunction in a patient in need thereof, comprising administering to the patient a composition comprising a therapeutically effective amount of a substance chosen from at least one of an isoprenoidal essential oil such as Tea Tree Oil; Terpinen-4-ol; (+)-Carvone; alpha-Terpineol; Cardinene; d-Carvone; l-Carvone; gamma-Terpinene; alpha-Terpinene; 1,8-Cineole; alpha-Terpineol; para-Cimene; alpha-Pinene; Limonene; (R)-(+)-Limonene; alpha-Thugene; Eucalyptol; (+)-Ledene; Cuminic Aldehyde; and Myrcene; the administration comprising contacting or scrubbing an affected area of skin or hair, or eyelid margin and lashes of the patient with the composition; also disclosed are a method for treating mange and mite infestations on a mammalian animal; and kits for in-office and at home treatments of the disorders.

Description

RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 676,692 filed on Apr. 30, 2005, the teachings of which are incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION[0002]Blepharitis, an inflammation of the edge of the eyelid, is a common clinical problem. Blepharitis occurs as an ulcerous (staph) form or nonulcerous (seborrheic) form, or as a combination of both forms. Mixed blepharitis is seborrheic with associated staph. Patients who suffer from blepharitis as a result of an ocular demodex infestation often present with a number of symptoms such as a foreign body sensation, redness and itching. The symptoms can become severe enough that the patient may require surgery to achieve relief. However, even invasive treatments such as surgery often result in no significant improvement, and / or a recurrence of the demodex infestation.[0003]Demodex mites, Class Arachnid and Order Acarina, are elongated ectoparasites. A...
