New glaucoma test could save millions from blindness

Conclusion Glaucoma is responsible for about 10 in 100 people registered blind in the UK. About 2 in 100 people over 40 in the UK have glaucoma, and around 10 in 100 of those aged over 75. Because there is no cure, but early treatment can often help slow or prevent damage, early diagnosis is important. Regular eye tests may pick up glaucoma, but often there's no sign of the disease until people have already begun to lose vision. That's why this test is interesting. If it can be shown to work well and safely, it could be a quick and efficient way to diagnose glaucoma before people have started to lose their sight. However, there's more work to do before we get to that stage. The initial trial results in 16 people need to be repeated among bigger groups, to be sure the results hold true. The researchers need to establish the best dose of the fluorescent dye. Importantly, they need to establish what number of white dots is normal, and what number suggests early glaucoma. This research only shows that people with glaucoma had more white dots, not what would be a good cut-off point for early diagnosis. Everyone should have a routine eye test at least every two years. This may include a test for high pressure in the eye, as well as a sight test. If a close relative has glaucoma, mention it to the optician to be sure they carry out appropriate checks. Some types of glaucoma can run in families, so if you do have a family history, more frequent tests may be recommended.  Links To T...
