It is a non-selective muscarinic receptor antagonist which causes mydriasis and cycloplegia
Tokyo, Japan) was used to obtain a measurement of the refractive error without cycloplegia
, and the average value of three repetitions was recorded.
In the control group, cycloplegia
refraction and SE were not significantly correlated with SFCT (p=0.
After 3-4 months of age, also assess ocular motility, cycloplegia
refraction and accommodation by dynamic retinoscopy.
Complete eye examinations were performed before surgery, including naked eye visual acuity, best-corrected vision, noncontact intraocular pressure (IOP), slit-lamp examination, binocular ophthalmoscope retinal examination, refractive error check before and after cycloplegia
, curvature of the cornea, and corneal thickness measurement using an ultrasound and corneal tomography.
All children underwent ophthalmological examination including visual acuity measurement, anterior segment and dilated fundus evaluation, retinoscopy with cycloplegia
, and intraocular pressure measurement.
This emphasizes the importance of inducing cycloplegia
for the evaluation of PPM (GONZALEZ ALONSOALEGRE & RODRIGUEZ, 1997).
Stereo-acuity Ability to perceive spatial TNO Stereo depth; it is a binocular test faculty which is achieved through horizontally disparate images for right & left eyes of the same object Test Illumination, Scale lux Static visual acuity 480 Letter score (theoretical range: 0 to 100) Refractive error 12 Spherical and cylindrical error with axis (Diopter) Contrast sensitivity 12 Log Unit Ocular alignment Photopic [greater Prism Diopter than or equal to] 25 Stereo-acuity 800 Range: 15 to 480 s/arc Test Description Static visual acuity Monocular and binocular visual acuity and best spectacle-corrected visual acuity (BSCVA) are assessed and recorded during archery Refractive error This measurement is performed with and without cycloplegia
was not performed in all children with error, so there could be overall underestimation of refractive errors and we were not able to collect further details regarding factors influencing compliance to spectacle use.
Auto-refraction with cycloplegia
in both eyes was performed using a PRK-5000 auto-refractor (Potec Co.
Retinoscopic examination was carried out under appropriate cycloplegia
In clinical practice, these agents are used to achieve cycloplegia
before refraction examination; to achieve pupil dilatation before fundus examination, surgery, and angiography; or to prevent synechia in the management of uveitis.
