The human lens is comprised largely of crystallin proteins assembled into a highly ordered, interactive macro-structure essential for lens transparency and refractive index. Any disruption of intra- or inter-protein interactions will alter this delicate structure, exposing hydrophobic surfaces, with consequent protein aggregation and cataract formation. Cataracts are the most common cause of blindness worldwide, affecting tens of millions of people1, and currently the only treatment is surgical removal of cataractous lenses.
Researchers at University of California San Diego have identified lanosterol as a key molecule in the prevention of cataract formation that points to a novel strategy for cataract prevention and non-surgical treatment. The abstract is freely available fromNature. If you have cataracts, you might want to purchase a full reprint while you can still read it.
Similar eye drops have been used to treat cataracts in Europe for many years.

The American Assoc of Ophthalmologists recommends the following.
A common condition among seniors, low vision can make everyday activities difficult, increasing reliance on loved ones and caregivers while increasing the risk of falls and depression. However, here are a few simple adjustments around the home that can lessen this dependency for those with less severe forms of low vision.
1. Place furniture in small groupings so less distance vision is required during a conversation
2. Set brightly colored accessories around the home to help with locating the items around them.
3. Brighter lighting can help with reading and activities such as sewing or cooking.
4. Embrace technology. There are a variety of technology-based tools for smartphones and tablets designed to aid people with low vision.
5. Tape down area rugs and remove electrical cords from pathways to decrease risk of falling and injury.
6. Keep up with eye exams.

Researchers have developed an application that can detect eye diseases like diabetic macular edema.
The move is aimed at general physicians who can detect the condition and refer the patient to a specialist.
“The idea is to detect and prevent diseases in general practice. We are not replacing the specialist. We want to know which patients have a disease and make an early detection,” said Dr Juan Carlos Altamirano Vallejo, medical director of the Medical and Surgical Centre for Retina.
For people with diabetes, this app will help them know whether they are suffering with macular degeneration, edema and diabetic retinopathy.
The software, developed in collaboration with biomedical engineers from the Spain-based the Monterrey Institute of Technology and Higher Education (ITESM) has been satisfactory and is expected to soon be marketed and incorporated the basic health system.
