We present a method for inducing elevated intraocular pressure (IOP), by injecting magnetic microspheres into the rat eye, to model glaucoma. This leads to strong pressure rises, and extensive neuronal death. This protocol is easy to perform, does not require repeat injections, and produces stable long-lasting IOP rises.

A Method to Induce Ocular Surface Inflammation in a Murine Model

This video demonstrates a method to induce ocular surface inflammation and meibomian gland dysfunction in a murine model. Stimulation of the mouse's immune system using an immunogen and later restimulation with the same immunogen promotes ocular surface inflammation, which causes plugging of meibomian gland secretion through neutrophil-produced aggNETs and leads to dry eye disease.

Ocular Kinematics Measured by In Vitro Stimulation of the Cranial Nerves in the Turtle

This protocol describes how to use an in vitro isolated turtle head preparation to measure the kinematics of their eye movements. After removal of the brain from the cranium, cranial nerves can be stimulated with currents to quantify rotations of the eye and changes in pupil sizes.
FAQs
The stimulus determines which mechanical response is observed. A pressure change may alter the eye’s shape or dimensions, whereas an applied force may produce measurable movement or localized deformation. Comparing the response with the magnitude and direction of the controlled stimulus helps characterize how strongly ocular tissues resist or accommodate deformation under defined experimental conditions.
Useful measurements include changes in ocular shape, dimensions, and movement recorded between an initial state and a stimulated state. These variables describe different aspects of the response: dimensional changes indicate expansion or contraction, while movement reflects displacement caused by the stimulus. Examining them together can provide a broader picture of tissue behavior than relying on one measurement alone.
These concepts describe how readily ocular tissues change under stimulation. Greater distensibility indicates a larger response to a given pressure or force, while greater resistance indicates less deformation under comparable conditions. Compliance refers to the relationship between the applied change and resulting deformation. Tracking these properties helps researchers compare mechanical behavior across conditions, disease states, or treatments.
A typical workflow establishes a baseline ocular shape, dimension, or position, applies a controlled pressure change or force, and records the resulting response with imaging or pressure-based methods. The pre-stimulus and post-stimulus observations are then compared to estimate deformation or movement. Consistent stimulus conditions and measurement timing are important for meaningful comparisons between experimental observations.
Imaging can document changes in ocular shape, dimensions, or movement directly, making spatial deformation visible or measurable. Pressure-based recordings instead capture information associated with the pressure condition used during assessment. Choosing between them depends on the response being examined and the available experimental design. In some studies, these approaches provide complementary information about ocular mechanical behavior.
The approach is useful when investigators need to compare ocular mechanics across disease progression, treatment effects, or controlled experimental conditions. Changes in measured deformation or resistance can indicate altered pressure regulation or tissue compliance. It therefore supports research into how eye structure behaves over time and how mechanical responses differ between comparison groups or following an intervention.
