Top-Fourteen of the Australian and New-Zealand Glaucoma Interest
Group Annual Meeting
July 21-22, 2006, Sydney, Australia
| Anne Brooks
The Australian and New Zealand Glaucoma Interest Group (previously the Australian and New Zealand Glaucoma
Club) held its Annual Scientific Meeting in Sydney from July 21-22,
2006. The invited speaker was Dr Anne Coleman from UCLA. Scientific
papers presented included both clinical and basic research, as well as
two Clinical Case sessions. Anne Brooks introduced the Inaugural Gillies
Lecture in honour of Dr Bill Gillies, who founded the Australian and New
Zealand Glaucoma Club as a time when there were no other special
interest groups within the Royal Australian and New Zealand College of
Ophthalmologists. He saw the Club as a way to bring together people with
an interest in glaucoma to foster a special interest group within
ophthalmology on the basis of equality and informality. Dr Gillies was
Chair of the Club from 1988 until 2005. After a very distinguished
career in Ophthalmology, including a term as President of the College
and the award of the Medal of the Order of Australia, he retired from
clinical practice on 30 June 2006. The Inaugural Gillies lecture was
given by Jonathan Crowston.
- Nutrition and Glaucoma - fruits and vegetables are associated with a
decreased risk of glaucomatous optic nerve damage in older women.
- Falls, Fractures and Visual Field Loss and Glaucoma - binocular visual
field loss is associated with an increased risk of falls and fractures
in older women. There is a greater risk of falls and fractures as
binocular visual field loss increases.
- Most HRT parameters, particularly the Moorfields Regression Analysis
parameters were significant in predicting the conversion to glaucoma in
participants in the Ocular Hypertension Treatment Study.
- Through imaging of live cells in a transgenic mouse model scientists
will be able to follow ganglion cell death longitudinally.
- Retrospective analysis of de-identified billing data from the
Australian Pharmaceutical Benefits Scheme for the potentially
inappropriate practice of co-prescribing topical and systemic
beta-blockers showed that approximately 20,000 concessional patients per
annum are affected. Healthcare stakeholders must alert professionals and
patients for the reduced hypotensive efficacy and increased potential
for systemic side effects from this practice.
- Optic nerve injury after excitotoxic injury to the retinal ganglion
cell somata show early pathological changes in the distal axon
characteristic of a dying back-type process.
- Eighty percent or more of glaucoma patients did not think that ocular
medication could have systemic side effects.
- Trypan Blue can identify the likely sites of cyclodialysis clefts in
patients who have had multiple operations, allowing a precise
application of surgery or laser therapy.
- After an acute rise in intraocular pressure, changes to the ganglion
cell cytoskeleton in the pig optic nerve head were seen. Fractional
axonal transport inhibition across the post lamina and lamina regions
was also demonstrated.
- A stepwise decrease in the mean age at diagnosis across Australian
patients with the Gln368STOP, Thr377Met and Pro370Leu MYOC mutations is
mirrored by a reciprocal increase in maximum recorded IOP and the
proportion of subjects requiring trabeculectomy.
- LMX1B has been implicated in Nail Patella Syndrome (NPS).
LMX1B
mutations were identified in 5/8 NPS probands. In total one case of NPS
with glaucoma and a LMX1B mutation, two cases of NPS with ocular
hypertension and mutations in LMX1B and one case of NPS with glaucoma
without a LMX1B mutation were found.
- CYP1B1 mutations have been identified in 16.2% of Australian probands
with Primary Congenital glaucoma. This is noticeably lower than that
reported in the Slovakian Gypsy and Saudi Arabian populations.
- The translation of genotype-phenotype and gene-mutation frequencies
are valuable to the clinician allowing a complete understanding of the
likely natural history and appropriate provision of genetic counselling.
- Eight shot argon laser peripheral iridoplasty for angle closure eyes
is effective.
