Source: Jiang, X., et al. Inducement and evaluation of a murine model of experimental myopia. J. Vis. Exp. (2019)This video demonstrates a procedure for inducing myopia in a mouse through the installation of a custom lens frame. The frame is secured to the exposed skull with dental adhesive, and concave lenses are inserted to shift the focal point behind the retina. This setup stimulates eyeball elongation leading to myopia.

We demonstrate the effect of scleral crosslinking with riboflavin and UVA on an axial elongation rabbit eye. Axial elongation was induced in 13 day-old New Zealand rabbits (male and female) by suturing their right eye eyelids (tarsorrhaphy).

Marketing Myopia

2024
Marketing myopia is a concept that highlights the shortsightedness of businesses when they focus too narrowly on their products or services rather than understanding and addressing the broader needs and wants of their customers. This myopic view can lead to a failure to recognize changes in consumer preferences and market dynamics, ultimately hindering long-term success. In order to avoid marketing myopia, businesses should adopt a customer-centric approach, continually adapt to evolving...

A rapid approach to investigate interactions and effects on molecular mechanisms related to the presence of antibodies in an intracellular environment is described. The method involves transfection of antibodies into live cells using a non-covalent complex formation based on a lipid formulation. The technique is adaptable to immortalized cell lines and primary cells.

Asthma: Pathogenesis and Management
0 Views •
2024
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms. Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
FAQs
Retinal signals responding to defocus can alter communication between the retina, choroid, and sclera. These signals are associated with changes that encourage ocular growth, rather than acting only as a visual sensation. The resulting tissue response helps explain how optical information is translated into structural remodeling, making the retina-to-sclera pathway central to studying myopia progression.
The scleral extracellular matrix helps determine the mechanical properties of the eye wall. During myopia pathogenesis, remodeling of this matrix can reduce scleral stiffness, making the tissue more permissive to axial elongation. This connection links molecular and cellular changes in the sclera with the larger structural changes that influence optical focus and disease progression.
Genetic susceptibility and visual environment can modify the biological pathways regulating ocular growth. They should therefore be considered interacting influences rather than isolated explanations. This perspective helps account for variation in risk among individuals exposed to similar conditions and supports research that examines inherited factors alongside visual experiences when evaluating myopia development.
Prolonged near work may modify pathways involved in myopia pathogenesis, but the available description places it alongside genetic susceptibility and broader visual-environmental influences. Treating it as one factor within a larger biological system avoids reducing myopia to a single behavior. This framing is useful when considering prevention strategies and differences in individual risk.
Mapping the links among retinal defocus signals, ocular growth, extracellular-matrix remodeling, and tissue stiffness provides a biological basis for assessing risk. It also helps identify where prevention efforts may influence growth-related pathways. Because genetic and environmental factors can modify these processes, effective assessment should consider both susceptibility and visual conditions rather than relying on one indicator.
A central treatment goal is slowing excessive ocular growth. The pathogenesis framework directs attention toward the pathways connecting retinal signals with choroidal and scleral responses, including changes in the scleral extracellular matrix. Treatments that slow growth may limit further structural change and help reduce the likelihood of later complications associated with myopia.
Myopia pathogenesis has importance beyond blurred distance vision because continued structural change can contribute to retinal degeneration, glaucoma, and myopic maculopathy. Understanding the underlying growth and tissue-remodeling pathways supports efforts to reduce these risks. It also connects biological research with prevention and treatment strategies intended to limit long-term ocular damage.
