Experimental Glaucoma Induced by Ocular Injection of Magnetic Microspheres

2015
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

2025
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.

Glaucoma is one of the major causes of blindness in the world. Elevated intraocular pressure is a major risk factor. Laser photocoagulation induced ocular hypertension is one of the well established animal models. This video demonstrates how to induce ocular hypertension by Argon laser photocoagulation in rat.

Three Dimensional Vestibular Ocular Reflex Testing Using a Six Degrees of Freedom Motion Platform

Cited by 4 •
2013
A method is described to measure three-dimensional vestibulo ocular reflexes (3D VOR) in humans using a six degrees of freedom (6DF) motion simulator. The gain and misalignment of the 3D angular VOR provide a direct measure of the quality of vestibular function. Representative data on healthy subjects are...

Intrinsically Disordered Proteins

2020
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...
FAQs
Genetic factors, aging, injury, infection, inflammation, and disrupted blood flow can each disturb ocular tissues through different biological pathways. These influences may act alone or in combination, producing cellular and molecular changes that affect visual function. Identifying the initiating factor helps researchers investigate disease progression and consider suitable prevention or treatment strategies.
Research examines how abnormalities in the cornea, lens, retina, optic nerve, and supporting structures relate to outcomes such as vision loss or pain. Comparing these locations helps distinguish which tissue changes accompany particular symptoms. This tissue-centered approach connects visible or functional problems with underlying biological alterations rather than treating all ocular conditions as identical.
Cellular and molecular findings provide a mechanistic link between an ocular condition and its clinical effects. Studying these changes allows investigators to relate altered tissue biology to symptoms and to identify processes that may be targeted by future interventions. This connection supports research ranging from disease investigation to drug development and gene-based therapies.
Eye examinations, imaging, and functional tests provide complementary information for evaluating the visual system. An examination can support clinical assessment, imaging can contribute information about ocular structures, and functional testing can help evaluate visual performance. Together, these methods help connect observed abnormalities with the biological changes under investigation and support diagnosis.
Ocular disorder research can inform prevention by clarifying how factors such as aging, injury, infection, inflammation, or disrupted blood flow affect the eye. It also supports drug development and gene-based therapies by linking biological changes to potential intervention strategies. The broader goal is to preserve existing vision or investigate approaches for restoring it.
They provide a setting for studying how genetic and environmental influences affect tissues, cells, molecular processes, and visual function. Biological research can connect these levels with clinical observations such as pain or vision loss. This integration makes ocular disorders relevant to investigations of disease mechanisms, diagnostic approaches, therapeutic development, and preservation of vision.
