Abstract

Brahisefalik köpekler anatomik yapılarından dolayı göz
hastalıklarına yatkın ırklardır. Kornea pigmentasyonu
ya da farklı isimleriyle korneal melanosis veya
pigmenter keratitis, brahisefalik köpek ırklarında en
fazla görülen göz lezyonlarından birisidir. Özellikle göz
kapağı ve kirpik anomalileri sonucu bu bölgedeki kılların kornea yüzeyinde oluşturduğu sürekli irritasyon,
hastalık etiyolojisinde önemli rol oynar. Bu çalışmada
amaç, brahisefalik köpek ırklarında sıklıkla meydana
gelen pigmenter keratitis’in ayrıntılı olarak değerlendirilmesi ve sağaltım sonuçlarının ortaya konulmasıdır.
Çalışma materyalini pigmenter keratitis tanısı konulan
73 köpeğin toplam 105 gözü oluşturdu. Pigmenter
keratitis, en fazla Pug ırkında görüldü. Anamnez bulguları ve klinik muayene sonuçlarına göre pigmenter
keratitisli köpeklerde körlük (n=8), görmede azalma
(n=72), konjunktivitis (n=12), oküler akıntı (n=48),
entropion (n=62), distikiazis (n=28), korneal opasite
(n=13), vaskülarizasyon (n=18) belirlendi. Cerrahi sağaltım için entropionda kantoplasti yöntemi tercih edilirken, distikiazis ve trikiasisde ise korneayı irkilten
kirpikler uzaklaştırıldı. Medikal sağaltım olarak sürekli
olarak siklosporin A ve sodyum hyaluronat damlalar,
korneadaki vaskülarizasyon ve opasite şiddetine göre
ise 1 hafta süreyle düzenli olarak deksametazon fosfat
damla uygulandı. Kapak ve kirpik defektlerinin düzeltilmesinden sonra irritasyonun ortadan kaldırılmasıyla
pigment göçünün belirgin şekilde azaldığı, medikal sağaltımın da eklenmesiyle pigment göçünün durduğu
görüldü.

Brachycephalıc Pıgmentary Keratıtıs In Dogs

Abstract

Brachycephalic dogs are predisposed to eye disorders
due to their anatomical structures. One of the most
common eye problem of brachycephalic breeds is
corneal pigmentation, also called corneal melanosis or
pigmentary keratitis. Chronic irritation of hair on the
corneal surface, especially in eyelid and eyelash
anomalies, plays an important role in etiology. The aim
of this study is to evaluate pigmentary keratitis which
occurs frequently in brachycephalic dogs and reveal
treatment outcomes. The study material consisted of
105 eyes of 73 dogs with pigmentary keratitis.
Pigmentary keratitis was most commonly seen in Pug
breed. According to the owners’ anamnesis and clinical
examination, visual loss (n=72), conjunctivitis (n=12),
ocular discharge (n=48), entropion (n=62), distichiasis
(n=27), corneal opacity (n=13) and vascularization
(n=18) were determined. For surgical treatment,
entropion was corrected with kantoplasty technique
and eyelashes were removed in distichiasis and
trichiasis. Cyclosporine and sodium hyaluronate drops
were continuously used for medical treatment of the
eye. Also, dexamethasone phosphate drops were
applied regularly for 1 week according to corneal
vascularization and opacity. After correcting the lid and
eyelash defects, it was seen that pigment migration
decreased with removal of chronic irritation to corneal
surface and stopped by the addition of medical
treatment
