SIR: We are making readers aware of the eye condition Glaucoma, which accounts wholly, or in part, for 13pc of those on the blind register, and yet this loss of sight is usually preventable if the disease is detected early and treated.

During our annual awareness campaign Frog Week, (from the initials of the words For Relief Of Glaucoma), we are seeking to alert as many people as possible to the fact, that, in its most common chronic form, this condition gives no warning symptoms. It is essential, therefore, that everyone over 40 (or earlier if there is glaucoma in the family), asks specifically for all three glaucoma tests, (eye pressure, field of vision and examination of the back of the eye), to be carried out next time they visit the optician (optometrist), for a sight test.

Frog Week is from June 15 to 21, and on Wednesday, June 10, there will be a free open meeting starting at 6.30pm, at the Exeter University, Main Campus, Lecture Theatre 2, Queens Building, Queens Drive, Exeter.

For more information, send a 9in x 7in sae, with 38p stamp, to I.G.A. King's College Hospital, Denmark Hill, London, SE5 9RS.

Mrs B M Wright.

Chief Executive.
