Yıl 2019, Cilt: 12 Sayı: 1, 13 - 19, 30.06.2019

Öz

Bu çalışmada Kars Bölgesinde yeni doğan
buzağılarda (0-3 aylık) rutin göz ve göz fundusunun muayenesi yapılarak retinal
anormalitelerin tip ve insidensi ile olası nedenlerin değerlendirilmesi
amaçlanmıştır. Çalışma materyalini değişik ırk ve cinsiyette 0-3 aylık 300 baş
buzağı oluşturdu. Bütün olgularda Atropin ile oluşturulan midriasis sonrası göz
fundusunun muayenesi yapıldı. Fundus muayenesinde optik disk, tapetal bölge,
nontapetal bölge ve retinal damarlar değerlendirilerek normal ve anormal
bulgular not edildi ve fotoğraflama işlemi gerçekleştirildi. Değerlendirmeye
alınan 300 baş buzağının 287’sinde (%95,66) klinik olarak herhangi bir problem
saptanmazken 13’ünde (%4,33) bilateral tam körlük problemi belirlendi.
Bilateral körlük saptanan 9 olguda (%3) retina ve optik disk problemi gözlemlendi,
4 olguda (%1,33) ise retina ve optik diskte herhangi bir anormal bulguya
rastlanmadı. Görme problemi olan 9 olgunun 1’inde optik disk hipoplazisi,
retinal dejenerasyon ve miyelinizasyon, 1’inde optik neuritis, 2’sinde optik
disk hipoplazisi, 1’inde korioretinitise bağlı retinal kanama, 1’inde
papilloödem, 1’inde retinal dejenerasyon, 1’inde papilloödem ve retinal
dejenerasyon, 1 olguda ise bir gözde optik neuritis ve retinal kanama, diğer
gözde de optik neuritis ve parsiyel retinal ayrılma tespit edildi. Bu
çalışmayla, bölgemizdeki sığır yetiştiriciliğinde büyük önem taşıyan görme
problemlerine ilişkin insidens bilgileri yanında, çeşitli sığır ırklarına
ilişkin normal fundus varyasyonları saptandı ve problem saptanan olgularda
fundusla ilgili problemlerin çeşitliliği belirlendi.

Determination of Retinal Abnormality Incidence in Newborn Calves by Fundoscopic Examination in Kars Region

Yıl 2019, Cilt: 12 Sayı: 1, 13 - 19, 30.06.2019

Öz

In the present study, type and incidence of
retinal abnormalities occurring in newborn calves (0-3 months) and its possible
reasons were evaluated by routine ophthalmic and ophthalmic fundus examination
in Kars region. The study was performed in 300 calves with various breeds, age
(0-3 months) and sex. In all cases, examination of the fundus of the eye was
performed after the midriasis with Atropine. During the fundic examination of
optic disc, tapetal and non-tapetal areas and retinal vascularity were evaluated.
Normal and abnormal findings were recorded and photographed. Clinical
examination showed that 287 of 300 (95.66%) calves were clinically normal,
bilateral full blindness were observed in 13 calves (4.33%). Retinal and optic
disk problems were present in 9 cases (3%), 4 cases (1.33%) were free of
retinal and optic disc problems. Optic disc hypoplasia, retinal degeneration
and myelinization (1 case), optic neuritis (1 case), optic disc hypoplasia (2
cases), retinal hemorrhagia due to corioretinitis (1 case), papilledema (1
case), retinal degeneration (1 case), papilledema and retinal degeneration (1
case), optic neuritis and retinal hemorrhagia in one eye, optic neuritis and
partial retinal separation were other findings observed in nine case with eyesight
problems. In conclusion, in the present study the incidence of eyesight
problems that is a significant problem in cattle breeding of our region and
normal fundic variation of various cattle breeds were determined. A variety of
fundic problems were also determined in animals with sight problems.
