Rodent models for glaucoma retinopathy and optic neuropathy

Area of Science:

• Ophthalmology
• Animal Models
• Glaucoma Research

Background:

• Animal models are crucial for understanding glaucoma etiology and pathology.
• Rodent models (rats and mice) are increasingly utilized due to eye similarities with primates and advanced techniques.
• Existing research highlights the need for comprehensive reviews of rodent glaucoma models.

Purpose of the Study:

• To survey research techniques for measuring intraocular pressure in rodents.
• To evaluate morphologic, biochemical, and functional changes in the retina, optic nerve head, and optic nerve.
• To describe individual rodent glaucoma models, including those with and without ocular hypertension.

Main Methods:

• Review of techniques for intraocular pressure measurement in rats and mice.
• Analysis of methods for assessing ocular tissue changes (retina, optic nerve head, optic nerve).
• Detailed description and comparison of various rodent glaucoma models.

Main Results:

• Identification of key techniques for evaluating rodent eyes in glaucoma research.
• Categorization of rodent models into those with and without induced ocular hypertension.
• Discussion of the technical considerations, theoretical concerns, advantages, and limitations of each model.

Conclusions:

• Rodent models offer valuable tools for glaucoma research, aiding in understanding disease mechanisms.
• A thorough understanding of available models and techniques is essential for effective glaucoma therapy development.
• This review provides a comprehensive guide to rodent models for glaucoma research.
