One hundred successive patients were operated on for cataract under periocular anaesthesia. The patients were divided into 3 groups to study the effect of extraocular compression on intraocular pressure. In the control group (C‐0), no compression was used. In the other 2 groups, compression was applied immediately after local injection of the anaesthetic for either 10 (C‐10) or 20 min (C‐20). In the control group, a periocular local anaesthetic increased the IOP in 27 of 36 patients, the average increase being 3.8 mmHg (at 10 min). Postanaesthetic compression of the eye led to a decrease in intraocular pressure, which is beneficial for the operative procedure. During the first 10 min, the mean intraocular pressure decreased by 3.1 and 4.0 mmHg in groups C‐10 and C‐20, respectively. In the C‐20 group, there was a further (1.3 mmHg) reduction in intraocular pressure between 10 and 20 min.
