Effects of 1% cyclopentolate hydrochloride on anterior segment parameters obtained with Pentacam in young adults Efeitos do cloridrato ciclopentolato 1% sobre os parâmetros do segmento anterior obtidos com Pentacam em adultos jovens

The assessment of anterior segment structures has become an important consideration for the planning of ocular refractive and cataract surgery, as well as for diagnosing and treating glaucoma and assessing corneal health. This assessment is typically performed by means of slit lamp biomicroscopy in clinical applications. An objective quantitative assessment of anterior segment structures is not adequate, and direct iridocorneal angle visualization can only be achieved using diagnostic contact lenses. Recently introduced anterior segment imaging technologies, such as rotating Scheimpflug imaging and anterior segment optical coherence tomography, pro mise to overcome these limitations. They offer quantitative information and qualitative imaging of the cornea, anterior chamber, and iridocorneal angle. Cycloplegic agents, which relax the ciliary muscle, are primarily used for detailed fundus examinations. They are also employed during surgery, refraction, and in the treatment of some ocular diseases, such as amblyopia, accommodative esotropia, and corneal traumas. In addition, they can also be used in the management of uveitis, in order to prevent adhesion of the iris. Their cycloplegic effects reduce ocular pain and photophobia in ocular inflammatory diseases. Atropine, cyclopentolate, and tropicamide are the most commonly used cycloplegic agents. Atropine produces the greatest amount of cycloplegia, making it the gold standard, but its effects are prolonged, and it can produce severe side effects. In contrast, cyclopentolate and tropicamide have relatively short durations of action, so they are used widely in clinical practice.
