Retinoskopi av katter : en validerande studie av undersökningsmetoden på katt

Abstract: Retinoscopy, also known as skiascopy, is an objective method for assessing therefraction of the eye. This method has been used for a long time, both in animalsand human patients. According to the literature, it has been postulated that it is notnecessary to obtain cycloplegia before the examination in lower mammals. Someauthors even mention that it can make the examination more difficult. Therefore itis not recommended. In this study of 21 cats of different ages, it has been shownthat cats can accommodate during the retinoscopy, even adult cats, which makesthe results unreliable. This implies that cycloplegia should be induced in thisspecies, for instance by application of atropine eye drops before the examination.
