AGE-RELATED MACULAR DEGENERATION
Age-related macular degeneration is a common, chronic, progressive, degenerative disease that causes central loss of vision due to abnormalities that occurs in the pigment, neural and vascular layers of the macula.
The macular disorder may have one or more of the following:
- Formation of drusen which are localized deposits of extracellular material usually concentrated in the macula
- Abnormalities in the retinal pigment epithelium (eg hypopigmentation or hyperpigmentation)
- Retinal pigment epithelium and choriocapillaris geographic atrophy
- Neovascular (exudative) maculopathy
Decreased central vision and distortion of seeing straight lines are the most common symptoms.

Patient Education

  • Instruct patients with age-related macular degeneration (AMD) on how to test their vision daily or at least weekly
    • While patients with exudative AMD or have had laser treatment, should be instructed on how to monitor the size of their blind spots or the appearance of new ones
  • Encourage high risk patients (eg with early AMD and/or family history of AMD) to have regular dilated eye exams for the early detection of the intermediate stage of AMD
  • For low risk patients, it is recommended to have comprehensive medical eye evaluation schedule as below:
    • Patients 40-54 years old every 2-4 years
    • Patients 55-64 years old every 1-3 years
    • Patients ≥65 years old every 1-2 years
  • Patients should be informed about the symptoms of progressing choroidal neovascularization (CNV) (eg progressive decrease in central vision) and counsel on the need for prompt consultation with an ophthalmologist
  • Smoking cessation should be done as this is the main modifiable risk factor for AMD
  • Diet that includes leafy green vegetables, fresh fruits and fishes rich in omega-3 fatty acids may help decrease the risk for AMD
  • Maintain an ideal body weight
    • Increased body mass index (BMI) and abdominal obesity have increased risk for AMD
  • Wear sunglasses with 100% protection against ultraviolet A and B (UVA and UVB) radiation in bright environments

Bisphosphonates have proven antifracture efficacy and remain to be the cornerstone of osteoporosis treatment. However, a drug holiday is of particular importance with bisphosphonates due to some signals with long-term use of the drug, including rare incidence of atypical femoral fracture (AFF) and osteonecrosis of the jaw (ONJ), says a leading endocrinologist at AFOS 2017.

Breast cancer patients have notably different microbiomes in the local breast tissue and urinary tract, a recent study reveals. Particularly, species in the Methylobacterium genus are reduced in the local breast tissue while the urinary tract is enriched in gram-positive bacteria.
