Top-Ten of the South African Glaucoma Society Meeting
July 29-31, 2005, Drakensberg, South-Africa
Ellen Ancker
Peter Netland was the guest-speaker at this meeting.
- Daytime phasing is a good alternative to 24-hour IOP phasing to
detect most IOP peaks.
- HRT change from baseline is often false positive, but almost never
false negative, HRT cup depth differs with changes in the cardiac
cycle.
- Six percent of patients with NTG have positive neuro-imaging of
compressive lesions; 60% of NTG progress despite 30% IOP lowering
treatment.
- Raised IOP effect of intravitreal triamcinalone can last up to
9 months, 1% need surgery or SLT, risk factors for IOP rise are
baseline IOP above 15 mmHg, CRVO, uveitis, younger age.
- Five dB loss with SAP equates to 25% RGC loss, 10 dB loss
to 40% RGC loss, a paracentral scotoma with 5 dB loss equates to 50%
RGC loss.
- Intra-operative use of 5FU in pediatric glaucomas has got no
additional benefit; intra-operative MMC is of no benefit with Ahmed
valve implants re IOP control and number of medication used
post-operatively.
- Aggressive immunomodulation with antimetabolites T-cell
inhibitors or alkylating agents increases filtration surgery outcome
in uveitic glaucomas dramatically to 94% success in 4 years.
- The incidence of pseudo-exfoliation in South African blacks is
7% over the age of 40 and 18% over the age of 70 years, XFS is a
cause of OAG in 9% of black South Africans.
- Combined phaco-trabeculectomy outcomes: two-site surgery results
in lower IOP versus one-site surgery; lower IOP with phaco versus
ECE.
- In Stuge Weber glaucoma surgery a two-stage drainage is better
than a trabeculectomy because of choroidal effusion with the latter
procedure.
