Randomized Controlled Trial
A pilot randomised controlled trial comparing the post-operative pain experience following vitrectomy with a 20-gauge system and the 25-gauge transconjunctival system.
To compare post-operative pain following 25-gauge (25G) and 20-gauge (20G) vitrectomy in the first week following surgery. ⋯ There was evidence that 25G resulted in less patient discomfort. However, pain was not a prominent feature in either group. We failed to find a significant advantage in 25G for patients or surgeons.

Comparative Study
Intraocular pressures after ketamine and sevoflurane in children with glaucoma undergoing examination under anaesthesia.
For accurate intraocular pressure (IOP) measurement in very young children examination under anaesthesia (EUA) may be necessary. Most anaesthetic agents used for EUA have some effect on IOP. We compared IOPs in children after ketamine and sevoflurane anaesthesia. ⋯ Sevoflurane lowers the IOP significantly compared with the IOP measured after ketamine. This difference is independent of the IOP level. It may be important to use ketamine as the induction anaesthetic agent when accurate IOP measurement is necessary during EUA for children.
