Issue 4: Macular Degeneration May 2010


Welcome to the fourth issue of IMAGE, Centre for Eye Health’s (CFEH) newsletter for optometrists.

This issue focuses on Age-Related Macular Degeneration (AMD), which accounts for a large proportion of irreversible low vision and blindness in Australia. Retinal Pigment Epithelium (RPE) detachment, subretinal fluids associated with neovascular membranes, and subretinal haemorrhages can be identified using the advanced imaging instruments available at the Centre.

Clinical Research Update

Recent studies reported at the 2010 Association for Research in Vision and Ophthalmology (ARVO) meeting provide useful insights on pterygia referral criteria (Ashizawa et al, abstract #2408) and understanding vision secondary to surgery (Shibata et al, abstract #2399).

Ashizawa et al showed that if pterygia had penetrated into the corneal stroma (4 of 7 cases), corneal scaring occurred secondary to surgery but not where invasion had not occurred below Bowman’s layer (assessed via anterior OCT imaging). Higher order aberrations were critical in understanding visual status of individuals with pterygia before and after surgery (Shibata et al).

CFEH assessment of your patient with pterygia will help you make informed decision in their management.

We thank Professor Minas Coroneo for helpful discussions.

I am very excited about the inaugural CFEH SCOPE event on Sunday 20th June and am looking forward to meeting with the 100 optometrists who will be attending. This CPD event is another example of how the Centre is assisting practitioners in providing best practice patient care.

Remember, CFEH has an extensive range of advanced eye-imaging equipment to detect, investigate and monitor eye disease at no charge to your patients. We look forward to receiving your referrals.

Case Report – Malika has diabetes and fluctuating vision

Malika, aged 64, has had Type 2 diabetes for 23 years, with a history of poor glycaemic control, hypertension and hypercholesterolemia. She scheduled an appointment with her optometrist after experiencing fluctuating vision for three weeks. Malika’s optometrist noted retinal micro-vascular changes during a dilated fundus exam and referred Malika to CFEH for further tests. What services would you request from CFEH to aid in the diagnosis of Malika’s condition?
