Top-Four of the Annual South African Glaucoma Society Meeting
Cape Town, South Africa, 2016

- The Kombo Ombo Primary SLT Study was a RCT Study with 324 patients. They
were treated with SLT or beta-blocker for 30 months. The results showed 30%
IOP reduction in 76% with timolol versus 58% with SLT. The cost of the SLT was
$ 10 versus $ 114 with Timolol treatment.
(Tarek Sharaawy, Geneva, Switzerland) - The success rates of a trabeculectomy with a fornix-based or limbus-based
conjunctival flap are comparable. The fornix-based blebs are more diffuse, less
avascular and have a low incidence of infection. But they experienced more symptomatic
hypotony and need earlier cataract surgery.
(Catherine Green, Melbourne, Australia) - Why are we operating late? Operating late increases the rate of complications.
Glaucoma surgery outcome is correlated to the number of pre-operative BAK. Each
additional drop containing BAK increases the risk of early failure by the factor
1.21.
(Tarek Sharaawy, Geneva, Switzerland) - The ‘Tipping Point’ of the RNFL thickness is a ~75 micron. Past the tipping
point structure and function change together. The floor effect is reached at
45-50 micron when the structure does not change anymore, only the VF. The use
of SAP as a sole method of detection of change may result in failure to detect
progression.
