Objective: Leopard Geckos (Eublepharis macularius) are popular pets and can be affected by a range of ocular disorders. Our objective was to report ocular findings in a group of healthy captive leopard geckos and to establish reference ranges for commonly performed ocular diagnostic tests.
Animals Studied: Twenty-six healthy male geckos aged 1 year old (n = 4) and >2 years old (n = 22).
Procedures: All animals underwent ophthalmic examination, corneal esthesiometry, modified Schirmer tear test (mSTT), rebound tonometry, conjunctival bacterial aerobic and fungal culture, and measurement of ocular dimensions. Student's t test was used to compare values of corneal esthesiometry, tonometry and mSTT between groups. Multiple correlations were assessed by Pearson correlation coefficient.
Results: All animals had a normal ocular examination. Tear production as measured with a mSTT (mean ± SD) technique was 3.1 ± 1.3 mm/min and tonometry values (mean ± SD) were 8.2 ± 1.7 mm Hg. Corneal touch threshold (median, range) was 4.4 cm, 2.5-5.0. Younger animals had a significantly increased corneal sensitivity compared to older animals (P = .0383). Results of culture showed no growth for fungal organism in any animals. Conjunctival bacterial isolation rates were low, with only 7/26 samples positive for nine bacterial species.
Conclusions: Leopard geckos are amenable to ophthalmic examination and ocular diagnostic database testing with minimal manual restraint.

An understanding of the dynamics of bone growth is key to interpreting life-history parameters of vertebrates. In this study, we used fluorochrome labels in captive leopard geckos (Eublepharis macularius) to track bone growth and intraskeletal variability from embryonic to adult growth stages. Thirteen individuals were administered fluorochromes from pre-hatching to 4 years of age.

Background: Doublesex and mab-3 related transcription factor (DMRT) 1, commonly found in all vertebrates, regulates the transcription of genes involved in the masculinization and maintenance of gonadal somatic cells and/or germline cell development. DMRT1 has a DNA-binding domain called the DM domain and a transcription regulatory region. Unlike the former, there is little knowledge about the latter transcription regulatory region.

Few cases of antemortem ovarian torsion and diagnosis have been described in reptiles. This case series reports clinical and ultrasound findings in five adult (aged 1-6 yr) female geckos (three leopard geckos [], one crested gecko [], and one gargoyle gecko []) diagnosed with unilateral ovarian torsion between 2019 and 2023. All animals presented with acute weakness associated with coelomic distension, and one suffered from chronic diarrhea and cachexia.

Reptilian skin coloration is spectacular and diverse, yet little is known about the ontogenetic processes that govern its establishment and the molecular signaling pathways that determine it. Here, we focus on the development of the banded pattern of leopard gecko hatchlings and the transition to black spots in the adult. With our histological analyses, we show that iridophores are present in the white and yellow bands of the hatchling and they gradually perish in the adult skin.
