Die Behandlung der Keratitis superficialis chronica des Hundes mit Strontium-90

Abstract

Corneal pannus is responsive to radiation therapy with Sr-90 and long-term benefit can be achieved. Side effects are minimal. Optimal sequencing of therapy and dosage still have to be examined.

Adjunctive cryotherapy for pigmentary keratitis in dogs: a study of 16 corneas

“…The cornea was divided into 24 sectors for documentation (Fig. ), as previously described by Grüning and Allgoewer . The extent of corneal pigmentation in each sector was graded from 0 (absence) to 3 (sector mostly pigmented).…”

“…In severe CSK, superficial keratectomy may be performed to excise heavily pigmented corneal stroma . Radiotherapy using beta irradiation or soft X‐rays has also been used.…”

Radiotherapy for canine chronic superficial keratitis using soft X-rays (15 kV)

“…The positive effect of radiotherapy on CSK was shown in a previous study in which Sr‐90 was used as source of beta‐rays 7,8 . There are only a few Sr‐90 applicators in use in human ophthalmology in Germany and these are not easily accessible for the treatment of dogs.…”

On the Actual State of Industrial Quality Assurance Procedures with Regard to 106Ru Ophthalmic Plaques

“…However, in the case of recurrent pterygium perioperative 20-kV soft Xray irradiation [21] is now an effective alternative to 90 Srirradiation. Furthermore, corneal pannus in dogs [10] is responsive to radiation therapy with 90 Sr, and long-term benefit can be achieved with minimal side effects. In radiotherapy of intraocular tumors, e.g., in the case of malign choroid melanomas, episcleral brachytherapy with 106 Ru ophthalmic plaques has proven to be successful [14,[16][17][18][19][20].…”
