Inclusion criteria
Inclusion criteria: 1. Patient must be willing to give written informed consent, make the required study visits, and follow instructions 2. Patient must be at least 50 years of age 3. Patients may be of any race or sex 4. Two groups of ARM patients may be included Group 1: If there is choroidal neovascularisation (CNV) or geographic atrophy (GA) in one eye, any level of ARM is permissible in the fellow eye provided visual acuity (VA) is equal to or better than logarithm of the minimum angle of resolution (logMAR) 0.3 Group 2: Clinical diagnosis of severe early ARM in at least one eye. =20 soft distinct or soft indistinct drusen or if fewer that 20 soft drusen, focal hyper pigmentation must be present. Visual acuity greater than or equal to 6/12 or 0.3 logMAR in the study eye (which may be both eyes).
Exclusion criteria
Exclusion criteria: 1. Any retinal laser therapy in the study eye 2. In Group 1 there should be no visible choroidal neovascularisation or geographic atrophy 3. History of any unstable medical condition or life threatening conditions, for example, cancer or renal failure, that would preclude scheduled study visits or completion of the study 4. History of ophthalmic disease in the study eye (other than ARM) that would compromise the visual acuity of the study eye 5. Patients currently on supplements containing the antioxidants C, E, Zn, L and Z will be asked to discontinue them and may, after a washout period of three months, be eligible for randomisation into the study 6. History of malabsorption 7. History of psychiatric disorder, which may interfere with compliance in taking study medication or attendance for study visits 8. Patients with known allergy against one of the active ingredients or the other excipients in the study medications
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome will be retinal acuity in the study eye at 12 months of supplementation. The level of significance for changes will be set at 0.05. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Change in distance visual acuity (DVA) in treatment and control groups at 12 months. Similar to the primary outcome the level of significance for changes will be set at 0.05. 2. Progression of ARM based on detailed grading of stereo colour fundus images. Progression is defined as a change of at least one step in the level of severity as gauged by the appearance or an increase in (a) drusen (size, frequency and extent), (b) focal hyper or hypopigmentation (area). 3. In vivo macular carotenoid signal strength. 4. Serum markers Vitamin C, lipid soluble vitamins, cholesterol. Data from all patients who continued supplementation for more than 12 months will be collected and analysed in order get as much information as possible regarding the changes of visual function during the duration of the study. These additional data will be analysed independently from the primary and secondary outcomes at 12 months of supplementation. | — |
