Abstract
RATIONALES Cholinergic modification by anticholinergic medication can produce adverse effects in central nervous system (CNS) and cyclopentolate is an antimuscarinic agent widely used for ophthalmologic management. We demonstrate a rare case of hyperactive delirium caused by topical administration of cyclopentolate in a patient with amnestic mild cognitive impairment (MCI) due to Alzheimer's disease (AD). PATIENT CONCERNS A 74-year-old man showed acute confusion after preparation for cataract operation in day surgery clinic. The patient became confused and agitated after instillation of topical cyclopentolate drop into the eye and the symptoms persisted over several hours. DIAGNOSIS Previously the patient had been diagnosed with amnestic MCI with the finding of bilateral medial temporal atrophy on brain magnetic resonance imaging. 18F-flutemetamol positron emission tomography scan demonstrated multifocal amyloid deposition in the brain. INTERVENTIONS The patient was closely observed with the supportive management. OUTCOMES The patient began to recover 5 h after the onset of symptoms and the cognitive function was reverted to previous state within 24 h. LESSONS It is well known that several drugs with anticholinergic effects used in perioperative periods make the patients susceptible to delirium, but even the topical administration of cyclopentolate for cataract surgery also produce adverse CNS effects in a vulnerable patient who is diagnosed with MCI due to AD in this case.

Abstract
PURPOSE To determine the optimal dosage of cyclopentolate for adequate cycloplegia with minimal side effects. METHODS A prospective randomized clinical trial of patients 3.5 to 20 years of age referred to a strabismus clinic during a 1-year period. Eligible patients were randomly divided into three groups. In Group 1, the cycloplegic effect of one drop of cyclopentolate was compared with two drops; in Group 2, the effect of two drops was compared with three drops; and in Group 3, the effect of one drop was compared with three drops. RESULTS This study includes 192 eyes of 96 patients with a mean age of 11.0 +/- 5.7 years. Strabismus was present in 43 patients (44.8%). A total of 146 patients (76%) were hyperopic, 33 (17.2%) were myopic, and 13 (6.8%) were slightly hyperopic or myopic at the two stages of the study. Overall, only 16 eyes, including 9 eyes in Group 1 (16.4%), 2 eyes in Group 2 (3.2%), and 5 eyes in Group 3 (8.6%), had > or = 0.5 D difference in spherical equivalent refractive error at two stages of the study; however, intergroup differences were not statistically significant (p=0.16, chi-square test). Within each group, the percentage of eyes with <0.5 D difference was significantly greater than those with > or = 0.5 D difference (p<0.001 in all three groups, binomial test). Side effects were more prevalent using more frequent drops. CONCLUSIONS A single drop of cyclopentolate 1% suffices for cycloplegic refraction. There were less frequent side effects using one drop of cyclopentolate, compared to two or three drops.

Abstract
Mydriatic drops are routinely administered to premature neonates to screen for retinopathy of prematurity. Adverse anticholinergic side effects, particularly convulsions and tachycardia have been reported in the pediatric age group following instillation of mydriatics for diagnostic fundus examination [1, 2]. Caffeine is frequently used for apnea of prematurity. In the neonatal intensive care unit, the combined use of caffeine and mydriatic drops is a common practice. Here we report two cases of atrial arrhythmias after neonatal eye exam that improved with conservative management. Both patients were receiving caffeine at the time of events.

Abstract
OBJECTIVES To investigate the presence, nature and relationship to age, sex, ethnicity and body mass index (BMI) of adverse reactions following routine cycloplegic eye drops in children. DESIGN Prospective observational cohort study. SETTING Ophthalmology outpatient clinic Dutch metropolitan hospital; February, March and April 2009. PARTICIPANTS Children aged 3-14-year-old children receiving two drops of cyclopentolate 1% (C+C) or one drop of cyclopentolate 1% and one drop of tropicamide 1% (C+T). Patients were categorised by age (3-6, 7-10 and 11-14 years), sex, ethnicity and body mass index (BMI) (low, normal or high). OUTCOME MEASURES Rate and nature of adverse reactions reported at 45 min following treatment. Crude and adjusted ORs for reporting an adverse reaction using stepwise regression analysis with BMI, age, ethnicity and sex. RESULTS 912 of 915 eligible patients participated (99.7%). Adverse reactions were reported for C+C in 10.3% and in C+T in 4.8% (42/408 and 24/504, p=0.002), respectively. Central effects were present in 95% in C+C and in 92% in C+T. Compared to C+T, an increased risk was present in C+C (crude OR 2.3 (1.4 to 3.9), p=0.002). Forward adjustment showed BMI to be an influencing factor in treatment (OR 3.1 (1.7 to 5.6), p<0.001). In a multivariate model, a dose of cyclopentolate remained associated with adverse reactions. Analysis per BMI and regime and age category and regime, indicated associations with low BMI (OR C+C 21.4 (6.7 to 67.96), p<0.001, respectively, C+T 5.2 (2.1 to 12.8), p<0.001) and young age (OR C+C 8.1 (2.7 to 24.8), p<0.001). CONCLUSIONS Adverse reactions were common and almost exclusively involved the central nervous system. Both presence and severity were associated with repeated instillation of cyclopentolate 1%, low BMI and young age. In specific paediatric populations, a single dose of cyclopentolate must be considered. Vital function monitoring facilities are advisable. Adjustment of guidelines is recommended.

Abstract
We present the case of a term neonate who underwent a diagnostic eye examination on day one for possible genetic disorders. Five minutes after Cyclomydril (0.2% clyclopentolate and 1% phenylephrine) eye drops were instilled, a focal seizure lasting for approximately one hour occurred. The electroencephalograph (EEG) was normal but the magnetic resonance imaging (MRI) revealed calcifications in the bilateral periventricular regions. Urine CMV-DNA and maternal serum CMV-IgM were both positive. Auditory brainstem testing suggested severe sensoneural hearing loss. The baby was treated for congenital CMV infection and did not have further seizures. In this case the congenital CMV infection may have been the predisposing factor to central nervous system (CNS) toxicity induced by cyclopentolate. The exact mechanism is unknown but severe neurological impairment may be considered a contraindication for cyclopentolate eye drops in the neonate. To our knowledge, this is the first report of seizures occurring within the first week of life secondary to cyclomydril eye drops in a term neonate.

Abstract
Cyclopentolate is widely used in ophthalmology for its intense mydriatic and cycloplegic activity. Systemic side effects have been described in both adults and children. Myoclonic seizure is a rare side effect of eye drops that are used in eye examinations. We report herein a case of convulsion in a three month- old girl following cyclopentolate hydrochloride and phenylephrine hydrochloride eye drops, which were used in advance of ophthalmoscopy for examination of retinopathy of prematurity (ROP). Physicians should be aware of the uncommon systemic side effects of cyclopentolate, and drops should be used in appropriate dosages.

Abstract
Ophthalmologists frequently use mydriatics both for diagnosis (retinal exploration, refraction tests) and for treatment. Cyclopentolate is used to induce quick and successful mydriasis for pediatric eye examination. Hypersensitivity reaction to cyclopentolate is very uncommon, especially in children. We report the case of a child who experienced a hypersensitivity reaction to cyclopentolate during preparation for an eye examination under cycloplegia.

Abstract
PURPOSE The aim of our study was to evaluate the frequency of side effects (ataxia, dizziness and dry mouth) due to systemic absorption of parasympatholytic eye-drops, before phacoemulsification. METHODS This single surgeon, prospective, randomized and controlled study included 303 consecutive patients selected to undergo phacoemulsification with topical and intracameral anesthesia. Patients were distributed in two groups; those receiving no mydriatics before surgery (n=151) as control group and those dilated with cyclopentolate 1% and tropicamide 1% eye-drops (n=152) as the study group. Ataxia, dizziness and dry mouth were recorded in both groups by the same observer. Surgery time and changes in systolic and diastolic blood pressures were noted. Note was also taken of the cases where pupil widening maneuvers and a second intracameral instillation of lidocaine 1% plus epinephrine 1/200,000 were needed. RESULTS Fifteen patients (9.9%) suffered ataxia in the study group vs. three patients (2%) in the control group. Twenty-three patients (15.1%) suffered dizziness in the study group vs. two patients (1.3%) in the control group. Thirty patients (19.7%) experienced dry mouth in the study group vs. ten patients (6.6%) in the control group. No significant changes in blood pressures, surgery time and pupil dilating maneuvers were noted between groups. The odds ratio for a second intracameral instillation was 2.0 in the control group vs. the study group. CONCLUSIONS Lidocaine 1% plus epinephrine 1/200,000 as an adjunct to topical anesthesia during phacoemulsification showed to be an effective and safe alternative to abolish side effects caused by systemic absorption of mydriatics eye-drops before surgery.

Abstract
A grand mal seizure is an unexpected, rare adverse event in a child receiving eye drops to dilate the pupils for an eye examination. A case is reported of a convulsion in a 23-month-old boy after he received Cyclogyl (cyclopentolate) and Neo-Synephrine (phenylephrine) eye drops before ophthalmoscopy. His serum sodium was 125 mEq/L, and he had low plasma pseudocholinesterase activity. Children exposed to organophosphate insecticides and other pseudocholinesterase inhibitors may be at risk for cyclopentolate toxicity.

Abstract
A 56-year-old woman was evaluated for the surgical correction of hyperopia (+3.0 diopters). Two drops of cyclopentolate 1% were instilled in both eyes for measurement of the cycloplegic refraction and wavefront analysis. Immediately after the second instillation, the patient reported drowsiness, dizziness, nausea, and fatigue. Ten minutes later, stimulatory central nervous system symptoms in the form of restlessness, cheerfulness, and a 20-minute-long roar of laughter were observed, interrupted by a new sedative phase. Basic medical and neurologic examinations were unremarkable except for gait ataxia. Four hours later, the examination was continued uneventfully. As surgical treatment of refractive errors and measurement of cycloplegic refraction using cyclopentolate become more frequent, ophthalmologists should be aware of this unusual acute event.

Abstract
BACKGROUND Because of its advantages, topical cyclopentolate is often preferred over the gold standard, atropine. The purpose of the study was to obtain an overview over current cycloplegia protocols and to estimate the likelihood of severe complications due to the use of cycloplegics. METHODS A questionnaire was sent to 107 German-speaking centres with a supposed high cycloplegia frequency. RESULTS 57 centres answered, whereby 1,112 cumulated years of experience with cycloplegia were available for analysis. The frequency of cycloplegias varied between 2 and 180/week/centre, median 25/week/centre. A cumulated amount of 1.7 million cycloplegias was computed. The average extrapolated experience with cycloplegia was 49,000 cycloplegias/30 years. Severe complications which would cause a medical follow up of several hours or which led to a follow up in a ward were named 47 times and 2 times, respectively. CONCLUSIONS During 30 years of a cycloplegia career with an average of 34 cycloplegias/week, one may expect 2-10 severe complications. In current practice, the patient risk of severe complications is very small. Health care professionals and parents should be informed about the frequent occurrence of light side effects in order to reach a good compliance with cycloplegia.

Abstract
BACKGROUND Cycloplegia is a traumatic experience for most children, as guttae cyclopentolate stings on instillation into the conjunctival sac. This may result in inadequate cycloplegia, difficulty in further examination and a child who is scared of both the doctor and the ophthalmology department. Guttae proxymetacaine hydrochloride 0.5% (Ophthaine, Proparacaine) is a topical local anaesthetic that does not sting on instillation. METHODS Eighty-eight consecutive children in the paediatric clinic were assessed. The response of the patient to previous use of cyclopentolate alone was assessed by the parents of the child using a grading scheme. The use of proxymetacaine prior to instillation of cyclopentolate was then assessed using the same grading system. RESULTS Seventy per cent of the children who received cyclopentolate alone were assessed to have cried and been unhappy. Ninety-one per cent of the children who received cyclopentolate after proxymetacaine were assessed to have shown no adverse reaction to the cycloplegia and remained happy. CONCLUSION This study shows that use of proxymetacaine prior to cyclopentolate results in atraumatic cycloplegia in children. This can confer multiple benefits on the doctor-patient relationship.

Abstract
Adverse reactions due to the administration of mydriatic eyedrops are not uncommon. In Spain, the most commonly used are phenylephrine, tropicamide and cyclopentolate hydrochloride. In this study, 37 patients with adverse reactions to the administration of mydriatic eyedrops were investigated from January 1993 to June 1997. The aim was to assess the reliability of the diagnostic methods used, particularly the adequate concentration of allergens and the introduction of conjunctival challenge as a safe and accurate diagnostic tool in those patients who could not be diagnosed by other methods. Phenylephrine was the drug most frequently causing sensitization (93.5%) among the 31 allergic patients. Preservatives were the cause in only 1. Patch testing detected allergy in 68.5% of the subjects. 2 concentrations (1% and 10%) and vehicles (pet. and aq.) were used for phenylephrine. The most reliable was 10% aq. Reading at D4 was more useful than at D2. The sensitivity of the patch test was low (72.4%) and its negative predictive value (NPV) poor (42%). In 24% of patients, allergy to phenylephrine was detected only by conjunctival challenge test. This diagnostic method is safe and helpful and has not previously been used to diagnose adverse reactions due to mydriatic eyedrops.

Abstract
In this prospective study, microdrops (mean drop volume 5.6 microl) and commercially available standard drops (mean drop volume 35.4 microl) of cyclopentolate, phenylephrine and tropicamide's clinical efficacy and systemic side effects were compared. Sixty-one infants requiring diagnostic pupil dilatation were studied for pupillary diameter, systemic blood pressure, heart rate and skin flushing changes related to the instillation of mydriatic drops. Both microdrops and standard drops of the drugs produced significant increase in pupillary diameter compared with the baseline (p<0.01). In cyclopentolate and phenylephrine groups, there was no significant pupillary diameter changes between microdrops and standard drops (p>0.05). Mean blood pressure increased significantly in infants given standard drops. There was no significant change in the group that was given microdrops. In our opinion, reduced volume of mydriatics can prevent possible side effects.

Abstract
PURPOSE To assess the role postoperative mydriatics play after extracapsular cataract extraction (ECCE) and posterior chamber intraocular lens (IOL) implantation in causing iris modifications and in controlling inflammation. SETTING Outpatients Department, Ninewells Hospital, Dundee, Scotland. METHODS The prospective study comprised 136 patients who had standardized ECCE. Half the patients used a mydriatic for 2 weeks postoperatively. Anterior chamber activity, pain, and eye redness were evaluated at 2 weeks postoperatively; pupil shape, peripheral anterior synechias, IOL position, and iris adhesions, at 6 weeks. RESULTS Iris-lens adhesions were significantly more common in the group using a mydriatic. There was no difference between the two groups in postoperative inflammation. CONCLUSION Mydriatics should not be used routinely after ECCE with posterior chamber IOL implantation.

Abstract
The indications, technique, and drugs for pupillary dilation in the pediatric emergency department have been discussed. Although mydriatic agents are relatively safe, they are not without risks. Physicians therefore need to familiarize themselves with possible adverse reactions that can result from their use. Even when using an appropriate agent, efforts must be made to limit systemic absorption.

Abstract
Cyclopentolate has been widely used as a cycloplegic and mydriatic agent for over 30 years. It has gained widespread use as the cycloplegic drug of first choice for most children over the age of 1 year and allows many optometrists and ophthalmologists to carry out quick, successful cycloplegic refractions with few complications. During this time very few side-effects have been reported with the most commonly used 1% solution. This paper outlines two cases in which a possible allergic-type reaction occurred shortly after the instillation of 1% cyclopentolate hydrochloride in 'Minims' form (Smith and Nephew). This article also reviews the uses and side-effects of cyclopentolate and aims to warn practitioners about the possibility of such reactions, ways of avoiding their occurrence and suitable measures to take should they occur.

Abstract
A 4.5 year old boy with cerebral palsy presented with seizures associated with facial flushing and tachycardia following the instillation of 1% cyclopentolate, a commonly used mydriatic in paediatric practice. He had no prior history of convulsions. This case demonstrates the uncommon, though serious, atropine-like side effect of cyclopentolate eyedrops (Cyclogyl, Alcon) in usual dosage in a brain damaged child without an epileptic focus.

Abstract
Adverse systemic reactions associated with the use of topical ophthalmic timolol, chloramphenicol, phenylephrine and cyclopentolate are surveyed, with special emphasis on precautions and contraindications for these ophthalmic drug preparations. Systemic reactions secondary to timolol, a beta-adrenergic antagonist indicate that it should be used with caution in patients with asthma or a history of asthma, chronic obstructive pulmonary disease or cardiovascular disease and in those patients receiving systemic administration of beta-blockers or verapamil. Because significant blood dyscrasias or aplastic anaemia have been reported following topical ophthalmic chloramphenicol, the only absolute indication in ocular conditions is an organism that is resistant to all other antibiotics. Both 2.5% and 10% phenylephrine have been associated with cardiovascular effects and should be used with caution in selected patients on monoamine oxidase inhibitors, tricyclic antidepressants or atropine or in those with hypertension, advanced arteriosclerotic changes, aneurysms, orthostatic hypotension, long-standing insulin-dependent diabetes and in children with low bodyweights. Central nervous system toxicity secondary to cyclopentolate is dose-related and can be avoided by use of minimal concentrations and avoidance of unnecessary repetition of administration. Occlusion of the nasolacrimal passage with finger pressure immediately after instillation of any eyedrop also decreases the amount of drug that is absorbed systemically.

Abstract
In comparison with that of adults, the smaller body mass of children raises questions of dosage. In addition, manifestations of ocular drug toxicity are different in some respects. The ocular drugs causing serious adverse ocular or systemic side effects in children include glaucoma medications, corticosteroids, phenylephrine, and the anticholinergic cycloplegics. The reported complications from using these medications in children will be briefly reviewed, and strategies for minimizing the risk of their adverse effects will be suggested, including a discussion of dosages and techniques of administration.

Abstract
Reports of isolated cases of necrotizing enterocolitis following administration of mydriatric medication and ophthalmologic examination prompted a comparison of the incidence of feeding difficulties 24 hours before and 24 hours after the ophthalmologic examination of 50 newborns. All infants had received cyclopentolate hydrochloride and phenylephrine hydrochloride before the examination. A critical review of the nursing notes showed more abdominal distention and gastric aspirates in the period following the examination than in the period preceding the examination. One infant developed necrotizing enterocolitis during the 24-hour postexamination period. This study demonstrates the risk of feeding intolerance following the ophthalmologic examination of neonates. These risks may be due to the known side effects of the mydriatics, to the physical stress of the examination, or to a combination of both factors.

Abstract
A drug registry was established at Southern California College of Optometry (SCCO) to study use rates and incidence of adverse side effects of the nine pharmaceutical agents in the California optometry law. Data were gathered in clinics of SCCO for 6 months and offices of 20 private practitioners for 3 months. Data included drugs used, the strength and dosage, patient age, sex, and racial or ethnic origin. Adverse drug reactions were reported in detail, including objective and subjective findings, duration of the reaction, and case disposition. A total of 12,493 drug applications were reported. A low incidence of adverse reactions, eight cases (0.208%), which produced no permanent effects, is sound evidence regarding the risk/benefit ratio in support of the use of pharmaceutical agents by optometrists.

Mydriatic and cycloplegic drugs: a review of ocular and systemic complications. AMERICAN JOURNAL OF OPTOMETRY AND PHYSIOLOGICAL OPTICS 1982; 59:162-77.

Abstract
Complications from mydriatic and cycloplegic drugs are rare compared with their extensive use. Adverse effects are often related to dosage or other factors. The ocular complications include increased intraocular pressure, pigmentation of the conjunctiva and cornea, pigment in the anterior chamber, lacrimal duct blockage, macular edema, corneal endothelium damage, hyperemia, allergy, discomfort, and blurred vision. The systemic complications are those common to sympathomimetic and parasympatholytic drugs and include tachycardia, hypertension, headache, faintness. pallor, trembling, excessive sweating, palpitations, arrhythmias, confusion, hallucinations, drowsiness, ataxia, flushed skin, high fever, dysarthria, thirst, dry mouth, convulsions, disorientation, nervousness, coma, and death. An understanding of all possible side effects is of paramount importance to those using these drugs in the treatment of anticholinesterase poisoning. This review is intended as a ready reference to the adverse effects of mydriatic and cycloplegic drugs.

Abstract
Symptoms of poisoning were noticed in a eight-year-old boy after prescribed application of cyclopentolate 1 per cent (as declared by manufacturing firm). Acute psychosis disappeared spontaneous 3,5 hours later. Pharmacological analysis of the eye-drops showed that concentration of active agent wasn't 1 per cent but 1.31 per cent.

Abstract
Cyclopentolate 1% is significantly less effective than atropine 1% at producing cycloplegia in 1-year-old children. If cycloplegic refraction is to be used for investigation or screening children for visual defects during the sensitive period, the more prolonged and profound cycloplegia following atropine could potentially have a disastrous effect on the development of vision. Cyclopentolate 1% would have to be used, and allowance made for its inadequacy as a cycloplegic.
