Abstract

Objective: To establish the central corneal thickness (CCT) of normal koi fish by ultrasonic pachymetry, and its relationship to age, sex, body length and corneal diameter.

Methods: Age, sex and body length of 33 koi fish (17 male and 16 female fish) were recorded. Horizontal and vertical corneal diameters of each eye were obtained using Jameson calipers. Central corneal thickness of all eyes was measured by ultrasonic pachymetry. Intraocular pressure (IOP) by rebound tonometry was obtained for a subgroup of nine koi (18 eyes).

Results: Mean central corneal thickness was 325.9 microm. Central corneal thickness of female koi was greater than CCT of male fish (P < 0.01). Central corneal thickness increased with increasing age overall and within both sexes (P < 0.01). Central corneal thickness increased with increasing body length (P < 0.001). For male and female fish, CCT increased with increasing horizontal and vertical corneal diameters (P < 0.01). Mean horizontal corneal diameter (HCD) was 8.05 mm, mean vertical corneal diameter (VCD) was 7.38 mm, and HCD was consistently greater than VCD. Mean IOP of a subgroup of these koi was 4.9 mmHg by rebound tonometry.

Conclusions: Koi CCT increases with increasing age, body length and corneal diameter.

锦鲤中央角膜厚度:年龄、性别、体长和角膜直径的影响。

目的:利用超声测厚法建立正常锦鲤角膜中央厚度(CCT)及其与年龄、性别、体长、角膜直径的关系。方法:记录33尾锦鲤(公鱼17尾，母鱼16尾)的年龄、性别和体长。用Jameson卡尺测量每只眼的水平和垂直角膜直径。超声测厚法测定各眼角膜中央厚度。用回弹眼压法测定了9只锦鲤亚组(18只眼)的眼压。结果:角膜中央平均厚度为325.9微米。雌鲤中央角膜厚度大于雄鲤中央角膜厚度(P < 0.01)。角膜中央厚度随年龄的增长而增加(P < 0.01)。角膜中央厚度随体长增加而增加(P < 0.001)。雄鱼和雌鱼的CCT随水平和垂直角膜直径的增加而增加(P < 0.01)。平均水平角膜直径(HCD)为8.05 mm，平均垂直角膜直径(VCD)为7.38 mm, HCD均大于VCD。这些锦鲤亚组的平均眼压为4.9 mmHg。结论:锦鲤CCT随年龄、体长和角膜直径的增加而增加。

期刊介绍： Veterinary Ophthalmology is a peer-reviewed, international journal that welcomes submission of manuscripts directed towards academic researchers of veterinary ophthalmology, specialists and general practitioners with a strong ophthalmology interest. Articles include those relating to all aspects of: Clinical and investigational veterinary and comparative ophthalmology; Prospective and retrospective studies or reviews of naturally occurring ocular disease in veterinary species; Experimental models of both animal and human ocular disease in veterinary species; Anatomic studies of the animal eye; Physiological studies of the animal eye; Pharmacological studies of the animal eye.
