Abstract

Prekorneal gözyaşı filmi (PGF), lakrimal fonksiyonel
ünitenin önemli parçalarından biridir. Evcil hayvanlarda aköz gözyaşı üretim
miktarının ölçümünde Schirmer gözyaşı testi (SGT) ile fenol kırmızısı pamuk
ipliği testi (FKPT) kullanılmaktadır. SGT’ye alternatif olarak geliştirilen
FKPT’nin minimal invaziv olması, uygulama süresinin kısalığı ve daha az refleks
gözyaşı stimülasyonuna neden olması gibi avantajları bulunmasına rağmen SGT’ye
oranla daha az tercih edildiği bilinmektedir. Sunulan çalışmada bölgemizde
yaygın bir şekilde yetiştirilen Kangal ırkı köpeklerde FKPT ile daha önce rapor
edilmeyen fizyolojik aköz gözyaşı üretim miktarının belirlenmesi amaçlandı.
Çalışmanın materyalini, 14’ü 1 yaş altı (7 Erkek, 7 Dişi, n=14, 28 göz), 14’ü
ise 1 yaş üstü (7 Erkek, 7 Dişi, n=14, 28 göz) olmak üzere eşit sayıda 2 gruba
(I. grup, II. grup) ayrılan toplam 28 adet Kangal ırkı sağlıklı köpek
oluşturdu. Deneklerin her iki gözünün aköz gözyaşı üretim miktarları, lateral
kantuslarına 15 saniye süreyle yerleştirilen fenol kırmızısı pamuk iplikleriyle
ölçüldü. Ölçümler sonunda her iki grubun sağ ve sol gözlerinden alınan aköz
gözyaşı üretim miktarı ortalamaları arasındaki fark istatistiki açıdan önemsiz
bulundu (P>0.05). Ölçüm ortalaması 27.55±0.25 mm/15 sn. olarak kaydedilen I.
grup ile ölçüm ortalaması 27.07±0.31 mm/15 sn. olarak saptanan II. grup
arasındaki fark da önemsiz bulundu (P>0.05). Yaş ve göz yönü gibi
değişkenler dikkate alınmaksızın tüm köpeklerin (n=28, 56 göz) fizyolojik aköz
gözyaşı üretim miktarı ortalaması ise 27.31±0.20 mm/15 sn. olarak kaydedildi.
Bu çıktılar, FKPT’nin Kangal ırkı köpeklerde aköz gözyaşı üretim miktarının
ölçümünde güvenli ve hızlı sonuçlar verdiğini göstermektedir. Elde edilen
verilerin bu alanda çalışan araştırmacılar ile klinisyenler tarafından referans
olarak alınabileceği düşünülmektedir.

Determination of the Physiological Aqueous Tear Production Rate by Using Phenol Red Thread Test (PRTT) in Kangal Breed Dogs

Abstract

Precorneal tear film (PTF)
is an important part of the lacrimal functional unit. Schirmer tear test (STT)
and phenol red thread test (PRTT) are used for the measurement of aqueous tear
production rate in domestic animals. Although PRTT which has been developed as
an alternative to STT, has advantages such as minimally invasive, shorter
application time and less reflex tear stimulation, it is less preferred than
STT. In the present study, it was aimed to determine the physiological aqueous
tear production rate that has not been previously reported with PRTT in Kangal
breed dogs, grown commonly in our region. The material of the study was
consisted of a total of 28 Kangal breed healthy dogs, allocated to two equal
groups (group I and group II), 14 lower (7 male, 7 female, n = 14, 28 eyes) and
14 higher (7 male, 7 female, n = 14, 28 eyes) than 1 years old. The aqueous
tear production rate of both eyes of the subjects was measured with phenol red
thread, placed in the lateral cantus for 15 seconds. The average of
physiological aqueous tear production rate of the all dogs, regardless of age
and eye side, was recorded as 27.31±0.20 mm/15 sec. The difference between the
average of the aqueous tear production rate taken from the right and left eyes
of both groups was not statistically significant (P>0.05). The difference
between the mean values of group I (27.55±0.25 mm/15 sec.) and group II
(27.07±0.31 mm/15 sec.) was also insignificant (P>0.05). These results show
that PRTT provides safe and rapid results in the measurement of aqueous tear
production rate in Kangal breed dogs. It is thought that the obtained data can
be taken as reference by researchers working in this field and clinicians.
