Informal care and support networks are therefore important. liaising with organisations, such as the royal national Institute of Blind people, the International glaucoma association and local patient support groups, can provide a means of additional help and support to improve the older person’s quality of life. The glaucoma research foundation will also provide information for newly diagnosed glaucoma patients and send free educational booklets to the patient and a relative. Because there is an increased familial risk of developing coag, relatives are advised to undergo regular sight tests every two to three years. eye tests are free for first-degree relatives of people with glaucoma aged 40 years and over in england (nhS choices 2008). If driving is essential for the older person, safety to drive should be verified by an ophthalmologist and the Driver and vehicle licensing agency (2009) guidelines should be followed.
