Rabbits have been widely used for studying ocular physiology and pathology due to their relatively large eye size and similar structures with human eyes. Various rabbit ocular disease models, such as dry eye, age-related macular degeneration, and glaucoma, have been established. Despite the growing application of proteomics in vision research using rabbit ocular models, there is no spectral assay library for rabbit eye proteome publicly available. Here, we generated spectral assay libraries for rabbit eye compartments, including conjunctiva, cornea, iris, retina, sclera, vitreous humor, and tears using fractionated samples and ion mobility separation enabling deep proteome coverage. The rabbit eye spectral assay library includes 9,830 protein groups and 113,593 peptides. We present the data as a freely available community resource for proteomic studies in the vision field. Instrument data and spectral libraries are available via ProteomeXchange with identifier PXD031194.

Purpose: This study reports the changes in aqueous humor dynamics (AHD) and biometric parameters associated with growth and maturation in male Dutch-belted rabbits.
Methods: In this prospective observational study, 20 male Dutch-belted rabbits were studied at 4-weekly intervals starting at 10 weeks through 38 weeks of age. Data collected included intraocular pressure (IOP), aqueous flow, outflow facility by tonography and fluorophotometry (acetazolamide method), episcleral venomanometry, central corneal thickness, corneal diameter, anterior chamber depth, and testicular volume.

Hydrolases in the eye play an important role in the metabolism of ophthalmic drugs, especially those administered locally to the eyes. With the growing interest in peptide-based therapeutics for treating eye disease, it has become increasingly important to characterize the enzymatic activities of ocular tissues against both small molecules and peptides to better understand their ocular metabolism. In this study, we characterized the activities of hydrolases, including carboxylesterase 1 and 2, arylacetamide deacetylase, paraoxonases, cytidine deaminase, fatty-acid amide hydrolase, and peptidases by incubating probe substrates in whole eye homogenates and vitreous humors from human donors and 3 preclinical species, including New Zealand White rabbits, Gottingen minipigs, and Cynomolgus monkeys.

Purpose: To assess whether levels of topotecan that are expected to be therapeutic against retinoblastoma tumors can be achieved within the retina and choroid by suprachoroidal injection (SCI) and to assess toxicity and safety in vivo.
Design: Pharmacokinetics and dose escalation toxicity study.
Subjects: New Zealand white rabbits.

Purpose: To evaluate Periplaneta americana extract (PAE) effects on corneal epithelial healing and fibrosis after superficial lamellar keratectomy (SLK) in rabbits.
Methods: SLK was performed on the right eyes of 48 New Zealand White rabbits, randomized into three treatment groups (n = 16/group): normal saline (NS), Tobradex eye drops (TE), and PAE group. Corneal opacity and epithelial defect area were quantified using slit-lamp imaging at postoperative days 3, 7, 14, and 28 (D3, D7, D14, and D28) and scored via the grading system.

The objective of this study was to develop a reliable, cost-effective, and rapid in vitro model employing real-time PCR to assess inflammatory responses in hydrogel-based systems, and to comparatively evaluate the anti-inflammatory efficacy of human serum (HS), serum derived from plasma rich in growth factors (sPRGF), and human amniotic membrane extracts (HAMe) incorporated into gelatin-based hydrogels. An in vitro model of corneal inflammation was established by quantifying IL-1β expression via qPCR in TNFα-stimulated SV-40 immortalised human corneal epithelial (HCE) cells. Hydrogels functionalised with HS, sPRGF, or HAMe sourced from proximal, medial, distal, or pooled amniotic regions were evaluated for their anti-inflammatory potential.
