Correct measurement of the intraocular pressure of children with glaucoma or suspected glaucoma is essential for diagnosis and therapy. Despite new non-invasive measurement methods most of the children are uncooperative during the ophthalmological examination. Therefore examination under anaesthesia is needed. A lot of perioperative factors influence the measurement of intraocular pressure. Established and safe anaesthetic regimes have been modified regarding these factors. Aim of the study is to evaluate, if a standardized anaesthetic protocol generates reliable and reproducible measured values.
