    Glaucoma from PC usage

    Dear Editor

    As a PC user this article interests me greatly, as I have noticed my eyesight deteriorating since working 11 hour a day shifts in front of 4 monitors and sometimes also using the computer again after work at home.

    From a lay man's perspective I would like to know more about how different types of screen affect the eyes, and indeed whether the problem may stem simply from levels of artificial...

    Dear Editor,

    This is in response to the response letter from Pieter Gouws, Ophthalmologist Glaucoma Fellow, Toronto Western Hospital, Toronto, Canada. "The incidence of glaucoma in Japanese workers is comparable to a white population" for the manuscript "Possible association between heavy computer users and glaucomatous visual field abnormalities: a cross sectional study in Japanese workers."

    Computers and glaucoma

    Dear Editor

    As my father, A W Mulock Houwer, was a professor of ophtalmology, I have always been interested in engineering associated with medical (particularly eye) afflictions. Therefore I would like to ask if there was any reference to the type of display used with the computers in Tatemichi et als study.[1] I realise that liquid crystal displays and plasma displays have only been in use for a short perio...

    Author's reply

    Dear Editor

    Ever since the publication of our study,[1] we have been overwhelmed with literally hundreds of inquiries, mostly on the safety of PCs in visual health. As Gouws pointed out correctly, many were misled after heavy coverage by lay media to think we had proven the harmful effect of PC use on the eyes.[2]

    In retrospect, we realise the importance of using a very clear language in the manuscript...

    The incidence of glaucoma in Japanese workers is comparable to a white population

    Dear Editor

    I congratulate the Tatemichi et al on an interesting study.[1] However, as this paper has been widely sited in the general press, I would like to point out that this study does not show that heavy computer use causes glaucoma as suggested by the international press agencies.

    The prevalence of open angle glaucoma is well known from various epidemiological studies and ranges from 1-3% in...
