The aim of this study was to assess the transmission of the ultraviolet (UV) radiation (200-400 nm) through intact enucleated globes of different species (dogs, cats, pigs, rabbits, horses, and humans) using spectrophotometry. Globes of cats (n = 6), dogs (n = 18), pigs (n = 10), rabbits (n = 6), horses (n = 10), and humans (n = 4) were analyzed. A 5-10 mm circular area of sclera and choroid from the posterior aspect of the globe was removed under a surgical microscope, leaving the retina intact in all species except the horse. Glass coverslips were added in horses and rabbits due to retinal and globe fragility. The %T of wavelengths from 200 to 800 nm were measured through the ocular media (cornea, aqueous humor, lens, and vitreous humor) and retina, and compared between species. The globes of cats and dogs allowed the most amount of UV radiation transmission, while those of pigs and humans allowed the least amount of UV radiation transmission. A small amount of UV radiation transmission through the ocular media was detected in the rabbit and horse. Results from this study will support further vision research that may be used to train companion, working, and service animals.
本研究旨在通过分光光度法评估不同物种（狗、猫、猪、兔、马和人）完整去眼球的对紫外线（200-400nm）的透射。分析了猫（n=6）、狗（n=18）、猪（n=10）、兔（n=6）、马（n=10）和人（n=4）的眼球。在手术显微镜下，从眼球后段切除 5-10mm 大小的巩膜和脉络膜圆形区域，除马以外，所有物种的视网膜均保持完整。由于马和兔的视网膜和眼球脆弱，加入了玻璃盖玻片。通过眼部介质（角膜、房水、晶状体和玻璃体）和视网膜测量 200-800nm 波长的 %T，并比较不同物种之间的差异。猫和狗的眼球允许最多的紫外线辐射透过，而猪和人的眼球允许最少的紫外线辐射透过。在兔和马中检测到少量的紫外线透过眼部介质。本研究的结果将支持进一步的视觉研究，这些研究可能用于训练伴侣动物、工作动物和服务动物。
