Various methods have been employed in an attempt to decrease the progression of<unk> , although studies show mixed results. Many<unk>  treatment studies have a number of design drawbacks: small numbers, lack of adequate control group, and failure to mask examiners from knowledge of treatments used. Among<unk>  specialists, mydriatic eyedrops are the most favored approach, applied by almost 75% in North America and more than 80% in Australia. A 2015 review suggested that increased outdoor time protects young children from<unk> . A 2020 study of global practice patterns used by paediatric ophthalmologists to decrease the progression of<unk>  showed behavioral intervention (counseling to spend more time outdoors and less time with near-work) to be favored by 25% of specialists, usually in addition to medications. Glasses and contacts The use of reading glasses when doing close work may improve vision by reducing or eliminating the need to accommodate. Altering the use of eyeglasses between full-time, part-time, and not at all does not appear to alter<unk>  progression. The American Optometric Association's Clinical Practice Guidelines found evidence of effectiveness of bifocal lenses and recommends it as the method for<unk>  control". In some studies, bifocal and progressive lenses have not shown differences in altering the progression of<unk>  compared to placebo. In 2019 contact lenses to prevent the worsening of nearsightedness in children were approved for use in the United States. This "MiSight" type claims to work by focusing peripheral light in front of the retina. Medication Anti-muscarinic topical medications in children under 18 years of age may slow the worsening of<unk> . These treatments include pirenzepine gel, cyclopentolate eye drops, and atropine eye drops. While these treatments were shown to be effective in slowing the progression of<unk> , side effects included light sensitivity and near blur. Other methods Scleral reinforcement surgery is aimed to cover the thinning posterior pole with a supportive material to withstand intraocular pressure and prevent further progression of the posterior staphyloma. The strain is reduced, although damage from the pathological process cannot be reversed. By stopping the progression of the disease, vision may be maintained or improved.
