distorted vision. Uncorrected refractive errors are frequent cause
of reduced vision in children so it is very important for children to
have an eye examination. Symptoms include blur vision, squeezing
the eyes, eye strain, headache etc. Some children can present with
strabismus.1
The prevalence rate of visual impairment caused due to
uncorrected refractive errors is estimated to be 153 million people,
of whom eighty lacs are blind.2 Refractive errors can be diagnosed
by vision examination and may be corrected with glasses and contact
lenses.3 High level of accommodative power in children affects the
refractive status of the eye as lens’ optical power and shape can be
altered by contracting ciliary muscles. Therefore, it is necessary to
relax the accommodation fully while assessing their refractive error.
In this regard cycloplegic drugs are instilled in eyes for accuracy
in measurements. Cycloplegic drugs produce paralysis of ciliary
muscles which is called cycloplegia. These drugs can be instilled
in the conjunctival sac, such as atropine, homatropine, tropicamide,
scopolamine and cyclopentolate, which are known as cycloplegics.
By paralyzing the parasympathetic nerve supply all accommodation
can be abolished and latent refractive errors become manifest.
Cyclopentolate produces a rapid and intense mydriasis and
satisfactory cycloplegia. Paralysis of accommodation and full
dilatation of pupil are usually completed within 1 hour and the effects
worn off within 24 hours; occasionally the duration of action is much
longer, even 3 or 4 days.4 Atropine is an anti–cholinergic drug used
to temporarily paralyze accommodation reex in children and also
as a mydriatic to dilate pupil. It is the most efcient cycloplegic
agent. Although it is considered a relatively safe drug, some local
and systemic side effects do occur. The recommended regimen for
atropine Cycloplegia has been 7 to 10 applications within 3 to 4 days.5
The purpose of this study is to nd out the best regime for atropine
instillation to achieve maximum cycloplegia. It will benet both the
practitioner and children while doing Cycloplegic refraction.

Abstract
Purpose: To determine the best regime for administration of atropine eye drops for
cycloplegia and to see the effect of cycloplegia on different types of refractive error.
Methods: This cross–sectional study was conducted in Pediatric Clinic, Mayo Hospital
Lahore, Pakistan in the duration of 3 months to assess the best regime for administration of
1% atropine eye drops for cycloplegia and to see the effect of cycloplegia on different types
of refractive error. Non probability purposive sampling was done and 30 patients of age
