Paediatric cycloplegia: A new approach

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.
