Abstract:

Due to the growth and development status, corneal thickness and hardness of infant's eye were different from that of adults. The range of normal intraocular pressure (IOP) of adults is not ideal for reference when assessing the IOP in infants and young children. In addition, due to the un-cooperation of infants, when measuring the IOP in infants, sedation is usually needed. Therefore, the measurement state is completely different from the adults. Studies showed that the IOP measured under sedation was significantly different from measuring in the conscious state. Multiple factors such as different ophthalmotonometer, the thickness of the central cornea, age and other factors can affect the measurement results of the IOP. Therefore, it is very important to select a suitable ophthalmotonometer for infants, and consider the related factors' influence for assessing the IOP in infants.  (Int Rev Ophthalmol,  2016,  40:     86-90)
