KÖPEKLERDE BRAHİSEFALİK PİGMENTER KERATİTİS

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
