Thygeson's SPK

      also called:

  • Thygeson's Superficial Punctate Keratitis (SPK), 

  • Thygeson's Superficial Punctate Keratopathy (SPK),

  • TSPK

                                    This page was last updated 05 January, 2009

People with Thygeson's sometimes wait years before being correctly diagnosed. Unfortunately, after receiving a correct diagnosis, it is hard to find information about Thygeson's because TSPK is a rare disease.

As I find new, scientifically sound information or useful web sites I'll add that new information. I welcome your input.

What does Thygeson's look like?  Jump here to see Elena's photos.

 In this photo the eye is illuminated by a slit-lamp. Thygeson's SPK is seen as the tiny lesions -- the white dots -- highlighted to the right of  the yellow arrow.  In many cases the person you see for your eye care may use rose bengal dye to verify the diagnosis.

 Typical Treatment

Comments

Corneal bandages (soft contact lenses)

Commonly used. Treats the symptoms, but isn't a cure.

NOTE: You cannot combine Lotemax and soft contact lenses (As with all ophthalmic preparations containing benzalkonium chloride, patients should be advised not to wear soft contact lenses when using LOTEMAX."

Topical Steroids (Click here to learn more about a particular medication )

Commonly used. Treats the symptoms, but isn't a cure.

   
Experimental treatments that haven't been fully investigated Comments

Cyclosporine

Limited clinical research; not yet a proven treatment. October 2003: Some new developments: RESTASIS™ ophthalmic emulsion may help. Click here for details.

Laser Surgery

   Confocal Microscopy of Thygeson's Superficial Punctate Keratopathy.

Laser surgery example: Photorefractive keratectomy (PRK) combined with phototherapeutic keratectomy (PTK) as a treatment.

Experimental, some single-case reports, limited clinical research, but not yet proven.

Possible connection between Bowman's Layer and TSPK

TREATMENT OPTIONS:

 Treatment

Comments

Corneal bandages (soft contact lenses)

Commonly used; treats symptoms, doesn't cure

Topical Steroids -- corticosteroid eye drops

(U.S. National Library of Medicine for more information) or click the FDA link below (you will need to enter the name of the drug or medication once you get to the FDA site)

 

    Fluorometholone ophthalmic -- Marketed as FML Forte Liquifilm® (Allergan) or Flarex® (Alcon).

    Loteprednol -- Marketed as  Alrex®  (loteprednol etabonate ophthalmic suspension 0.2%) or Lotemax®(loteprednol etabonate ophthalmic suspension 0.5%)

Commonly used; treats symptoms, doesn't cure. Use only as needed and with care to avoid or minimize side effects, such as patients with diabetes being more likely to develop cataracts or glaucoma with use of corticosteroids. If used long-term, have an ophthalmologist check interior eye pressure every 6-12 months.

 

NOTE: You cannot combine Lotemax and soft contact lenses (As with all ophthalmic preparations containing benzalkonium chloride, patients should be advised not to wear soft contact lenses when using LOTEMAX."
 

Cyclosporine

Experimental and unproven. A 1999 investigation in Germany found positive results in 70% of patients.  And check out another case from James Freund. 

Also: October 2003: Some new developments: RESTASIS™ ophthalmic emulsion may help. Click here for details.

Laser Surgery

Experimental, anecdotal, but not yet proven. PTK 1999 update. (Refer also to the journal  Cornea , 20(4): 425-426, 2001) If you go there, do a search under Thygeson's and his article abstract will pop up.

This other article is a case study of only one patient. It suggests promising results, though the treatment has not yet been evaluated in a controlled study.

Corneal Bandages (Soft Contact Lens) and Topical Steroid Drops are most commonly prescribed for symptom treatment, but do not eliminate the cause.

Cyclosporine...

New report 23 Dec 2008:

Hasanreisoglu , Murat;  and Avisar , Rahamim; Long-term topical cyclosporin A therapy in Thygeson's superficial punctate keratitis: a case report,   Cases Journal 2008, 1:415doi:10.1186/1757-1626-1-415, Published: 23 December 2008

Clinical investigation: Topical cyclosporine A in Thygeson's superficial punctate keratitis;        T. Reinhard, Rainer Sundmacher; Eye Hospital, Heinrich Heine University, Moorenstraße 5, D-40225 Düsseldorf, Germany Tel. +49-0211-8117320, fax: +49-0211-811 6241; 9 March 1998

The March 1999 issue of PRIMARY CARE OPTOMETRY NEWS has an article on page 21 about Dr. James Freund in New Albany, Indiana. He reports that a 1% Cyclosporine solution has been effective in eliminating Thygeson's SPK symptoms.

January 2002 update:

"Treating Thygeson's with cyclosporin. To date it has proved the most effective means of treatment for the condition and the drug is becoming more readily available by pharmacist. I have one patient who is a veterinarian using cyclosporin (Optimune) with great success. It is equally effective in relieving symptoms keratitis sicca associated with Thygeson's. Thank you for referencing my article in primary care optometry March 1999. If you run into patients having difficulty locating cyclosporin please direct them to my website so they can contact me. www.dr4ureyes.com Warmest regards, James Freund"

You can obtain cyclosporine, with your doctor's prescription, from Leiter's Pharmacy, in San Jose, California.

In Spring 2000, two Connecticut 7th graders decided to do a science fair project on Thygeson's. These kids did a great job. They won a 3rd prize in the fair. Their site's archived links are old. Click here to check it out.bigline8.gif (2060 bytes)
