To report ophthalmic examination, biometry, phenol red thread test (PRTT), intraocular pressure (IOP), and histologic findings from a private collection of inland bearded dragons (Pogona vitticeps).
Fourteen inland bearded dragons.
Complete ophthalmic examinations were performed on all animals, including slit-lamp biomicroscopy, indirect ophthalmoscopy, fluorescein stain, phenol red thread test, and rebound tonometry. B-mode ultrasonography was used to measure anterior chamber depth, axial lens thickness, vitreal chamber depth, and axial globe length. Horizontal corneal diameter was estimated using ImageJ software. Histologic assessment was obtained for one of the bearded dragons that died following the study period.
The median PRTT value was 7.27 mm/15 seconds. Mean IOP was 6.29 ± 1.60 mm Hg and 2.14 ± 1.37 mm Hg using the dog and undefined calibration settings, respectively. Median axial globe length was 11.75 mm. Mean anterior chamber depth and mean lens thickness were 2.06 ± 0.35 mm and 3.38 ± 0.45 mm, respectively. Median vitreal chamber depth was 6.79 mm. Mean horizontal corneal diameter was 5.138 ± 0.346 mm. Two distinct ocular phenotypes were observed, with two of the bearded dragons having corneal globosa, deep anterior chambers, and tufts of iridal vessels and fibrillar material extending into the anterior chamber.
The ultrasound biometry, PRTT, and rebound tonometry results may serve as a guideline for ophthalmic parameters in healthy bearded dragons. Examination and testing of greater numbers of animals are necessary to establish true reference ranges and determine if the observed ocular phenotypes represent normal variants or pathologic changes.
报告内陆刺蜥（Pogona vitticeps）私人收藏的眼部检查、生物测量、苯酚红丝试验（PRTT）、眼压（IOP）和组织学发现。
14 条内陆刺蜥。
对所有动物进行全面的眼科检查，包括裂隙灯生物显微镜检查、间接检眼镜检查、荧光素染色、苯酚红丝试验和回弹眼压计检查。使用 B 型超声测量前房深度、晶状体轴向厚度、玻璃体腔深度和眼球轴向长度。使用 ImageJ 软件估计水平角膜直径。对研究期间死亡的一只刺蜥进行了组织学评估。
中位数 PRTT 值为 7.27mm/15 秒。使用犬和未定义校准设置，平均眼压分别为 6.29±1.60mmHg 和 2.14±1.37mmHg。中位数眼球轴向长度为 11.75mm。平均前房深度和平均晶状体厚度分别为 2.06±0.35mm 和 3.38±0.45mm。中位数玻璃体腔深度为 6.79mm。平均水平角膜直径为 5.138±0.346mm。观察到两种不同的眼部表型，其中两只刺蜥的角膜呈球形，前房深，虹膜血管和纤维状物质簇延伸到前房。
超声生物测量、PRTT 和回弹眼压计结果可作为健康刺蜥眼部参数的指南。需要对更多数量的动物进行检查和测试，以确定观察到的眼部表型是否代表正常变异或病理变化。
