Topical atropine is used as a cycloplegic, to temporarily paralyze the accommodation reflex, and as a mydriatic, to dilate the pupils. [15] Atropine degrades slowly, typically wearing off in 7 to 14 days, so it is generally used as a therapeutic mydriatic, whereas tropicamide (a shorter-acting cholinergic antagonist) or phenylephrine (an α-adrenergic agonist) is preferred as an aid to ...
Tropicamide induces transient stinging and a slight and transient rise in intraocular pressure in the majority of patients. It may cause redness or conjunctivitis (inflammation) and also blurs near vision for a short while after instillation (care must be taken, and the patient must only drive when vision returns to normal).
Laser vitreolysis is a possible treatment option for the removal of vitreous strands and opacities (floaters). In this procedure an ophthalmic laser (usually a yttrium aluminium garnet (YAG) laser) applies a series of nanosecond pulses of low-energy laser light to evaporate the vitreous opacities and to sever the vitreous strands. When ...
Low myopia usually describes myopia between −0.50 and −3.00 diopters. [65] Moderate myopia usually describes myopia between −3.00 and −6.00 diopters. [65] Those with moderate amounts of myopia are more likely to have pigment dispersion syndrome or pigmentary glaucoma. [83] High myopia usually describes myopia of −6.00 or more.
Cognitive function decline (Confusion, memory loss and difficulty in concentration) [18] paralysis, Tachycardia, [19] Hypotension (Anticholinergics are histamine-inducing, leading to vasodilation during anaphylactic reaction, hence a dropping in blood pressure), [20] constipation, dry mouth, dry eyes, hypohidrosis/ anhidrosis, blurry vision, or ...

Spherical aberration exacerbates myopia in low light (night myopia). In brighter conditions, the pupil constricts, blocking the more peripheral rays and minimizing the effect of spherical aberration. As the pupil enlarges, more peripheral rays enter the eye and the focus shifts anteriorly, making the patient slightly more myopic in low-light ...
A new long-acting preventive HIV drug could reach the world’s poorest countries by the end of 2025 or early 2026, a global health official told Reuters on Tuesday. The ambition is to start ...
