Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases. The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

Drug Toxicity: Risk factors
0 Views •
2026
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Ultrasound Cyclo Plasty in Eyes with Glaucoma

Glaucoma is a chronic disease with progressive degeneration of optic nerve fibers resulting in decreased visual field. Elevated intraocular pressure is considered the most important and the only treatable risk factor. This manuscript describes a simple, surgeon-friendly, non-incisional technique, named Ultrasound Cyclo Plasty, for reducing intraocular pressure in glaucoma patients.

A Magnetic Microbead Occlusion Model to Induce Ocular Hypertension-Dependent Glaucoma in Mice

Here, we present a protocol to induce ocular hypertension in the murine eye that results in the loss of retinal ganglion cells as observed in glaucoma. Magnetic microbeads are injected into the anterior chamber and attracted to the iridocorneal angle using a magnet to block the outflow of aqueous humour.

(2015) This video demonstrates in vivo imaging of retinal microglia in a mouse model of glaucoma. A transgenic mouse with fluorescent protein-expressing retinal microglia is positioned under an ophthalmoscope. Infrared illumination is used to locate the optic nerve head (ONH), and the focal plane is...
FAQs
Risk factors can affect several parts of the eye’s vulnerability. Impaired aqueous humor drainage may contribute to elevated or fluctuating eye pressure, while reduced optic nerve resilience or altered ocular blood flow may increase susceptibility to damage. This is why assessment considers multiple characteristics rather than relying on pressure or any single risk factor alone.
High or fluctuating eye pressure can increase the likelihood of progressive optic nerve damage, whereas reduced optic nerve resilience may make the nerve more vulnerable. These mechanisms are distinct but relevant to the same outcome, vision loss. Considering both helps explain why people with similar pressure measurements may not have identical risk profiles.
Yes. Glaucoma can occur without the listed personal, genetic, or medical characteristics. Risk factors change the likelihood of disease but do not determine whether it will occur. Consequently, the absence of family history, high pressure, myopia, diabetes, steroid exposure, or prior eye injury does not by itself exclude glaucoma.
Clinicians use the overall risk profile to support targeted eye examinations, earlier diagnosis, and ongoing monitoring. When risk appears important, pressure-lowering treatment may also be considered as part of care. The purpose is to identify progressive optic nerve damage and respond before vision loss becomes noticeable, when preserving vision may be more achievable.
A relevant history includes family history, increasing age, ethnic background, myopia, diabetes, steroid exposure, and previous eye injury. Information about high or fluctuating eye pressure is also important. Reviewing these details helps place examination findings in context and can support decisions about the timing and intensity of eye examinations and monitoring.
Early recognition directs attention toward examinations and monitoring before progressive optic nerve damage produces noticeable symptoms. It can also support earlier pressure-lowering treatment when appropriate. Because the intended outcome is preservation of vision, risk assessment functions as a preventive strategy rather than waiting for visible vision loss to prompt evaluation.
