  • Value-based medicine: Let's get it right
    Steven M. Kymes

    Dear Editor

    In a fine recent editorial, Drs. Melissa and Gary Brown raised issues at the nexus of health policy and clinical science [1]. As utility assessment is relatively new to the visual sciences, understanding both the assumptions behind this work and the consequences of relaxing those assumptions is essential for high quality research and appropriate interpretation of the results.

    The use of com...

  • Relevance of angle closure in Asians

    Editor,
    In their article Foster et al have addressed an issue of relevance to developing countries that have a high prevalence of angle closure. The likelihood ratio of a positive test using results that we have reported (sensitivity 61.9% and specificity 89.3%) is approximately 6 which is similar to the LR for the authors' 15% cutoff. Invocation of pupillary block to explain the discrepancy seems r...

  • Authors' reply
    Vasileios Peponis

    Dear Editor,

    We appreciate the comments of Sridhar et al. regarding our letter: “The role of corticosteroids in fungal keratitis: a different view” published in your journal [1]. The authors comment on our recommendation for a gradual tapering of corticosteroids in cases where steroids were used for the treatment of initially misdiagnosed fungal corneal infections.

    As mentioned in our cases rep...

  • Prevention of visual field defects after macular hole surgery

    Editor,
    We read with interest the article by Culliance and Cleary on the method of prevention of visual field defects after macular hole surgery. In their series, one group of 82 eyes received conventional pars plana vitrectomy surgery with mechanical induction of posterior vitreous detachment (PVD) around the optic disc followed by complete posterior cortical vitreous removal. Twenty-two percent of these...

  • Re: Causes of childhood blindness
    Anita Panda

    Dear Editor

    I read with interest the World View article by Ezegwui et al.[1] entitled: "The Causes of Childhood blindness: results from schools for the blind in South Eastern Nigeria". Childhood blindness has profound consequences not only for the individual but for the family and community. Approximating the average life span at 60 years, the man-year loss caused by childhood blindness is roughly six-fold, which...

  • Investigating the response of periocular triamcinolone for Thyroid Associated Ophthalmopathy.
    Damian B Lake

    Dear Editor

    We read with interest the article by Ebner et al [1] investigating the efficacy of periocular triamcinolone for the treatment of Thyroid Associated Ophthalmopathy (TAO) and the presence of ocular or systemic adverse effects also previously published in 2001 [2]. The study used patients with TAO of less than 6 months duration previously untre...

  • Susceptibility to ocular autoimmune disease

    Editor,
    We read with interest the Newsdesk piece in the March 2000 issue of the journal, commenting on recent studies indicating a conceptual shift in the understanding of the molecular basis of differential susceptibility to organ-specific autoimmune diseases. However, we were disappointed that the Newsdesk piece was restricted to studies of the animal model of multiple sclerosis and not that of uveitis....

  • Silicone oil in diabetic vitrectomy
    David McLeod

    Dear Editor

    Castellarin and colleagues [1] recount their recent experience of infusing silicone oil in a small series of patients with advanced diabetic eye disease, either during primary vitrectomy (12 eyes) or after earlier surgery had failed (11 eyes). They compare their results with previous reports and conclude that silicone oil remains a useful adjunct in diabetic vitrectomy. However, their conclusions and h...

  • Developmental mosaicism in the eye may follow the “lines of Blaschko”
    Carsten H. Meyer

    Dear Editor

    Developmental mosaicism in the eye may follow the “lines of Blaschko” Ruggieri M et al. nicely described the ophthalmological manifestations in segmental neurofibromatosis type 1 [1]. They postulated that segmental NF1 is a somatic mosaicism for the NF1-gene expressing two different embryological tissues in the eye.

    Previously we described a patient with unilateral sectorial hyperpigmented ski...
