研究的目的是评估不同年龄犬屈光不正的发生和范围。共有99名临床健康者,混合品种中头颅犬被纳入研究,并根据当前的人类/宠物类比图分为三个不同的年龄组:40名成年人(23名男性,17名女性,1-8岁,3-70公斤),21名老年人(14名男性,7位女性,6-11岁,7-42kg),和38名老年病科(22名男性,16位女性,8-13岁,5-45公斤)。所有的狗都接受了眼科检查,包括Schirmer撕裂试验,眼压测定,生物显微镜,和检眼镜。在自动折射术之前,既没有滴眼剂也没有药物镇静剂。使用手持式Retinomax3(Righton)自动验光仪对屈光状态进行双侧评估。使用Statisticav12软件(ANOVA和t检验)对结果进行统计分析。P值<0.05被认为是显著的。Emmetropia,定义为>-0.5D和<+0.5D的屈光状态,在36%的成年人身上发现了,43%的老年人,和38%的老年患者。1%的成年人出现屈光参差,当两只眼睛的屈光力不同≥1.0近视≤-0.5D和远视≥0.5D时,在23%和41%的成人眼球中发现了9.5%的老年犬和5.5%的老年犬以及24%和33%的老年犬和15%和47%的老年犬,分别。成年犬和老年犬的近视最大值分别为-2.5D和-2.75D,分别。成年犬和老年犬远视的最大值分别为1.75D和2.5D,分别。组间没有发现统计学上显著的相关性。屈光不正是不同年龄狗的常见屈光状态。在所有年龄组中,屈光不正混床犬中最常见的屈光状态是远视。
The purpose of the study was to evaluate the occurrence and range of refractive errors in dogs of different ages. A total of 99 clinically healthy, mixed-breed mesocephalic dogs were included in the study and divided into three different age groups according to the current human/pet analogy chart: 40 adults (23 males, 17 females, 1-8 years old, 3-70 kg), 21 seniors (14 males, 7 females, 6-11 years old, 7-42 kg), and 38 geriatrics (22 males, 16 females, 8-13 years old, 5-45 kg). All the dogs underwent an ophthalmic examination, including Schirmer tear test, tonometry, biomicroscopy, and ophthalmoscopy. Neither eye drops nor pharmacological sedatives were administered before the autorefractometry. The refractive states were assessed bilaterally using a hand-held Retinomax 3 (Righton) autorefractor. The results underwent statistical analysis using Statistica v12 software (ANOVA and t-test). A P-value < 0.05 was considered as significant.
Emmetropia, defined as a refractive state > -0.5 D and < +0.5 D, was found in 36% of the adult, 43% of the senior, and 38% of the geriatric patients. Anisometropia was found in 1% of the adult, 9.5% of the senior and 5.5% of the geriatric dogs when the refractive power of the two eyes differed ≥ 1.0 myopia ≤ -0.5 D and hyperopia ≥ +0.5 D were found in 23% and 41% of the adult eye globes as well as 24% and 33% in the senior dogs and 15% and 47% in the geriatric dogs, respectively. The maximal values of the myopia in the adult and geriatric dogs were -2.5 D and -2.75 D, respectively. The maximal values of the hyperopia in the adult and geriatric dogs were 1.75 D and 2.5 D, respectively. No statistically significant correlation was found between the groups. Ametropia is a common refractive state for dogs of different ages. The most frequent refractive state in ametropic mixed-bed dogs in all age groups is hyperopia.
