Induced myopia, also known as acquired myopia, results from various medications, increases in glucose levels, nuclear sclerosis, oxygen toxicity (e.g., from diving or from oxygen and hyperbaric therapy) or other anomalous conditions. Sulphonamide therapy can cause ciliary body edema, resulting in anterior displacement of the lens, pushing the eye out of focus. Elevation of blood-glucose levels can also cause edema (swelling) of the crystalline lens as a result of sorbitol accumulating in the lens. This edema often causes temporary myopia. Scleral buckles, used in the repair of retinal detachments may induce myopia by increasing the axial length of the eye. Index myopia is attributed to variation in the index of refraction of one or more of the ocular media. Cataracts may lead to index myopia. Form deprivation myopia occurs when the eyesight is deprived by limited illumination and vision range, or the eye is modified with artificial lenses or deprived of clear form vision. In lower vertebrates, this kind of myopia seems to be reversible within short periods of time. Myopia is often induced this way in various animal models to study the pathogenesis and mechanism of myopia development. Degree
The degree of myopia is described in terms of the power of the ideal correction, which is measured in diopters:
Myopia between −0.00 and −0.50 diopters is usually classified as emmetropia. Low myopia usually describes myopia between −0.50 and −3.00 diopters. Moderate myopia usually describes myopia between −3.00 and −6.00 diopters. Those with moderate amounts of myopia are more likely to have pigment dispersion syndrome or pigmentary glaucoma.
Reactive gastropathy, chemical gastropathy also called gastritis of « C type » or "chemical gastritis" is an abnormality in the stomach caused by chemicals, e.g. bile, alcohol, and characteristically has minimal inflammation. Cause
Reactive gastropathy has a large number of causes, including:

Alcohol use disorder. Bile reflux, such as may be seen post-Billroth II. NSAIDs. Diagnosis
The diagnosis is by examination of tissue, e.g. a stomach biopsy. Relation to gastritis
Reactive gastropathy is morphologically distinct entity  that can be separated from gastritis, which by definition has a significant inflammatory component. As a reactive gastropathy may mimic a (true) gastritis symptomatically and visually in an endoscopic examination, it may incorrectly be referred to as a gastritis. Even aware of the underlying etiology of the pathologic process, e.g. NSAID use, the label "chemical gastritis" is applied to a chemical gastropathy. See also
