AGE RELATED MACULAR DISEASE - August 2013

Early age related macular degeneration (AMD) is characterised by drusen (small and large) and focal pigmentary changes. Patients with early AMD but no distortion do NOT usually require referral, except for other reasons e.g. partial sight registration, LVA’s or cataract. These patients can be referred via the usual route (NOT fast track). However, patients may just require increased reading additions, advice on lighting, diet and to stop smoking. If appropriate. AREDS preparations should be recommended to patients with large drusen and / or pigmentary changes.

Late AMD can be divided in late dry and late wet AMD. The late dry AMD is geographic atrophy involving the fovea. The ’wet’ AMD is characterized by the development of new blood vessels beneath the retina (choroidal neovascularisation). The sub-classification is no longer relevant in Lucentis therapy. This requires urgent referral for consideration on Lucentis therapy (subject to referral guidelines).

Which patients to refer?

Use of this form is only for patients registered with GP’s in LAMBETH, SOUTHWARK, LEWISHAM, BEXLEY, BROMELY & GREENWICH.

Patient’s symptoms are very important – a recent onset of symptoms such as distortion scotoma, shadow or patch in the central vision is more likely to represent wet AMD, than simply a gradual worsening, blurring or difficulty with vision which is more likely to be related to the dry form, or cataract etc. If the VA is unchanged, it is unlikely that the patient will have wet AMD.

Fluorescein angiography and OCT are the mainstay for the diagnosis of wet AMD, the Amsler grid has a significant high false positive rate and has limited value.

NICE FAD on Lucentis states that treatment should be available to patients who have a VA of 6/96 or better in the affected eye without permanent structural damage to the fovea.

Local Referral Guidelines for Wet AMD (urgent – 2 weeks to treatment)

Visual loss and VA in affected eye – 6/96 or better

Recent sudden onset of central distortion (usually less than 6 months)

Fundal appearance suggestive of choroidal neovascularisation, such as haemorrhages and exudation.

Patients should be advised that treatment may not appropriate in every case.

If VA <6/96 - non-urgent referral to local eye department for consideration of LVA assessment.

Referrals using either the fax reporting form or the wet amd rapid access referral form to include the following information:-

Patient’s details and telephone number Patient’s refraction and VA

Affected eye and duration in weeks Referring Optometrist or GP name and address

These referral notes have been devised for general GUIDANCE only. They do not remove from practitioners their professional responsibility to each patient, who should all be dealt with on an individual basis.

PATIENTS WHO ARE MONOCULAR OR HAVE OTHER RISK FACTORS MAY CONSTITUTE A HIGHER RISK
