Abstract

This study was performed to evaluate the seasonal variation of intraocular pressure (IOP) values in normal Sapsaree dogs. Sapsaree dogs (n = 474) clinically free from ophthalmic disease were included in this study, and both eyes were examined in each dog. An applanation tonometer (Tonopen$^{(R)}$ XL) was used to measure IOP values in both eyes. Data obtained from both eyes were stratified by factors thought to affect IOP values including age, gender, hair coat type as well as season of measurement. The IOP results were compared by ANCOVA to verify the effect each factor had on IOP, and an ANOVA test followed by a Bonferroni post hoc test was used for further analysis. The overall mean ${\pm}$ SD IOP value was $19.1{\pm}3.7$ mmHg (range: 8 to 28 mmHg) in the present study. Only seasonal variation showed a significant effect (P < 0.001), on IOP values. IOP values measured in winter ($20.4{\pm}3.4$ mmHg) and summer ($17.1{\pm}3.6$ mmHg) were significantly higher and lower, respectively, than those measured in other seasons. These results suggest a seasonal variation has a significant effect on the IOP of normal dogs. This may prompt further research and possible modification of current veterinary ophthalmic references.

본 연구는 정상개에서의 계절에 따른 안압의 변화를 평가하기 위해서 실시되었다. 총 474마리의 안질환이 없는 삽살개의 양안에 대해서 편평안압계(Tonopen$^{(R)}$ XL)를 이용해서 안압을 측정하였다. 측정된 결과를 바탕으로, 안압에 영향을 줄 것으로 예상되는 요소의 유의성과, 각 요소의 군내 차이를 통게적 방법을 통하여 검증을 실시 하였다. 전체 삽살개의 평균 안압 및 표준 편차는 $19.1{\pm}3.7$ mmHg (범위: 8 to 28 mmHg) 이었다. 계절적 요소에서만 안압 변화에 대한 유의성이 검증 되었고(P < 0.001), 그 외 나이, 성별, 모색과 관련된 유의성은 확인되지 않았다. 겨울에 측정된 평균 안압 수치($20.4{\pm}3.4$ mmHg)와 여름에 측정된 평균 안압 수치($17.1{\pm}3.6$ mmHg) 는 다른 계절의 평균 안압에 비하여서 신뢰구간 내로 각각 높게 그리고 낮게 측정 되었다. 이상의 결과를 바탕으로 계절적 변화는 정상 개의 안압에 영향을 줄 것으로 판단되며, 본 연구는 후속되는 수의 안과 연구와 수의 안과 임상에 유용한 자료가 될 것으로 사료된다.
