  • Alcohol delamination of the corneal epithelium for recalcitrant recurrent corneal erosion syndrome:
    Lawrence W Hirst

    Dear Editor

    I commend the authors for yet another treatment for this potentially disabling and common affliction. I note that one important component of this treatment requires the mapping of the site of the erosion during an attack with this area being singled out for the localised 4-6mm of treatment. However, in most patients that I have treated over the years the area of erosion is healed by the time they seek...

  • Authors' response: Mechanism of action of bimatoprost.
    Louis B. Cantor

    Dear Editor,

    We thank Dr. Camras for his interest in our report on levels of bimatoprost and its free acid in the aqueous humour of cataract patients after a single topical dose of bimatoprost [1] and welcome the opportunity to respond to his comments. We are in agreement with Dr. Camras that the results of our study [1] and those of his previously reported study [2] are similar, showing low nanomolar concentrat...

  • Authors' reply: Vitamin A deficiency during pregnancy and congenital microphthalmos
    Christian E Decock

    Dear Editor,

    We would like to thank the authors Hornby and Gilbert for their interesting letter referring to our case report of bilateral colobomatous microphthalmos with orbital cyst.[1] Their remarks and view are relevant and demand further clarification.

    Because our intention was to investigate more in depth the origin of the cyst fluid and wall and because of space limitations, we were not able to...

  • Intraocular pressure rise during dilatation
    Nathan M. Radcliffe

    Dear Editor

    We read with great interest a recent report by Siam et al., “The amount of intraocular pressure rise during pharmacological pupillary dilatation is an indicator of the likelihood of future progression of glaucoma.” These authors report that the likelihood of optic nerve progression (defined by the disc damage likelihood scale, the glaucoma staging system 2, or both) in open angle patients is related t...

  • Bevacizumab for polypoidal vasculopathy should be evaluated in a cross cultural population
    Shree K Kurup

    Dear Editors

    We read with great interest, the illuminating article by Drs Gomi, Sawa and Tano. Our limited experience (4 Afro-American patients) with intravitreal bevacizumab (IVB) for polypoidal vasculopathy (PPV) has been more positive.

    We had reported the first success early this year in terms of lasting remission [1]. Furthermore, I enclose details on another patient who had PPV OU, in all likeliho...

  • Cost effectiveness of cataract surgery
    Ediriweera Desapriya

    Dear Editor

    According to the Canadian Community Health Survey, approximately 82% of the population of seniors aged 65 – 80+ (3,000,000 seniors) reported having vision problems in Canada. [1] Cataracts are the leading cause of vision impairment among seniors. Between the period of 1994 – 2003, proportions of seniors with cataracts rose from 14% – 20% with populations aged 75 and over accounting for higher percentage...

  • Tobacco alcohol amblyopia - Authors reply
    Raed Behbehani

    Dear Editor

    We appreciate the comments of Grzybowski et al. about our article. We agree that the term "tobacco alcohol amblyopia" is not very accurate and does not specifically describe the underlying cause of vision loss. It may also not fit the "historic" description of the condition. However, the term is still used widely to describe a spectrum characterized by optic nerve dysfunction and selective involvement of...

  • Cataract surgery in England
    Simon P Kelly

    Dear Editor

    We read with interest the paper by Keenan [ref 1] and colleagues.

    We recently studied the 2005/06 Hospital Episode Statistics (HES) data for cataract and have reached similar conclusions. We agree with the authors’ observations that as NHS cataract surgery rates (CSRs) in England have increased significantly in recent years, several questions are now raised. What is the appropriate CSR in a d...

  • Use of Avastin in rat models: Comments.
    Yuksel Totan

    Dear Editor

    We have read Manzano et al’s insightful paper[1] with interest and appreciated the comments concerning the inhibitory effects of bevacizumab on corneal neovascularisation (NV). However, the manuscript had some important aspects that need to be clarified. Cumulative data from numerous basic and clinical studies strongly implicates the central role of VEGF in ocular and corneal angiogenesis. Binding all free-ci...

  • Vitamin A deficiency and possible link with colobomatous malformations
    Stella J Hornby

    Dear Editor

    We read with interest the letter by Decock et al regarding the rare congenital ocular malformation (orbital cyst and bilateral colobomatous microphthalmos). [1]

    The female child reported was the product of a mother with documented vitamin A deficiency (VAD) during the second trimester of pregnancy after previous gastric bypass surgery for morbid obesity. The authors do not report the sympto...
