Adherence of patients with age-related macular degeneration to AREDS 2-recommended nutritional supplements.

BACKGROUND: The Age-Related Eye Disease Study 2 (AREDS 2) proved the benefit of vitamin and mineral supplementation in preventing advanced age-related macular degeneration (AMD). AREDS 2 supplements are indicated for patients with either bilateral intermediate AMD (AREDS category 3) or unilateral neovascular AMD (AREDS category 4). AIMS: The aims of this telephone survey were to identify the rate of adherence of patients to AREDS 2 supplements and the factors associated with non-compliance in these patient groups. METHODS: A patient telephone survey was conducted in an Irish tertiary care hospital. Patients were identified by chart review, and their AREDS categorization was reconfirmed. A telephone consultation was conducted with each patient to assess their compliance with the micronutrient supplements. RESULTS: We identified 120 patients who met the AREDS criteria for supplementation. Of these, 103 patients were graded as category 4, and 17 patients were graded as category 3. Almost a fifth (18%) were current smokers. Under two-thirds (60%) of the patients were taking AREDS 2 supplements. Of the remainder, 83% of patients did not recall being advised of their benefit. The cost was cited by 10% of patients as a reason for non-compliance. CONCLUSION: The ophthalmologist not only has a duty of care to treat the neovascular complications of AMD, but they must also strive to improve patient compliance with AREDS supplements. The cessation of smoking needs to be actively promoted in order to stop preventable vision loss in patients with AMD.

Neuro-ophthalmological manifestations of Behçet's disease.

BACKGROUND: The neuro-ophthalmological manifestations of Behcet's disease (BD) are rare, and data regarding their characteristics and outcome are lacking. OBJECTIVE: To report prevalence, main characteristics and outcome of neuro-ophthalmological manifestations in BD. PATIENTS AND METHODS: This is a retrospective monocentric study of 217 patients diagnosed with neuro-Behçet's disease (NBD), of whom 29 (13.3%) patients presented with neuro-ophthalmological manifestations (55% of men and mean±SD age of 26±8 years). All patients underwent a detailed ophthalmological examination and were followed up in the internal medicine and the ophthalmology departments. RESULTS: Neuro-ophthalmological manifestations were the first presentation of BD in 45% of patients and developed later in the course of the disease in 55% of patients. They are divided into parenchymal (PM) and non-parenchymal (NPM)-related manifestations in, respectively, 13 patients (45%) and 16 patients (55%). PM included papillitis in seven patients (53.8%), retrobulbar optic neuritis in four patients (30.8%) and third cranial nerve palsy in two patients (15.4%). NPM included papilloedema related to cerebral venous thrombosis in all 16 patients, of whom 6 patients (37.5%) had sixth cranial nerve palsy. At initial examination, 93.1% of patients had visual alterations, including mainly decreased visual acuity visual field defects and/or diplopia. All patients were treated with corticosteroids and 79% of patients received immunosuppressive agents. After treatment, the visual outcome improved or stabilised in 66.7% of patients while it worsened in 33.3. The mean±SD logarithm of the minimum angle of resolution visual acuity improved from 0.4±0.3 at diagnosis to 0.2±0.3 after therapy. 10.3% and 3.4% of patients were legally blind at diagnosis and after therapy, respectively. CONCLUSION: Neuro-ophthalmological manifestations of BD represented 13% of NBD. They could be potentially severe and disabling. Prompt treatment is the key factor in improving visual outcome.
