  • Surgical embolus removal in retinal artery occlusion
    Sohan S Hayreh

    Dear Editor

    I was interested to read the article by Garcia-Arumi and colleagues on "Surgical embolus removal in retinal artery occlusion".[1] The authors claim that "Surgical removal of retinal arterial emboli seems to be an effective and safe treatment for RAO (retinal artery occlusion)".

    Briefly, the study was based on 6 eyes with temporal branch retinal artery occlusion (BRAO) and one with central re...

  • Authors' response
    Susan P Mollan

    Dear Editor

    We thank Pushpoth and Sandramouli for their wide-ranging critique of our paper discussing previous isotretinoin use in potential military aviator recruits.[1] We cannot agree with their comment that the finding of 2 of 47 candidates, with clinically abnormal dark adaptation (DA) and 11 with electroretinogram (ERG) abnormalities does not justify further screening of this population. Aircrew recruits...

  • Secondary paracentral retinal holes following internal limiting membrane removal
    Adrian Rubinstein

    Dear Editor

    We read with interest the article by Steven et al.[1] on their finding of secondary paracentral retinal holes following internal limiting membrane peel. We have also reported on 4 eyes of 4 patients that developed iatrogenic eccentric macular holes following vitrectomy with ILM peeling for idiopathic macular holes.[2] In their report, Steven et al treated 3 of the 7 patients with argon laser photocoagula...

  • Randomised control trial of topical ciclosporin A in steroid
    Jeffrey Chiu Fai PONG PONG

    Dear editors

    We read with interest the article 'Randomised controlled trial of topical cyclosporin A in steroid dependent allergic conjunctivitis' (Br J Ophthalmol. 2006 Apr;90(4):461-4.) This article evaluated the use of cyclosporine A in treating steroid dependent severe allergic conjunctivitis, and has the merit of a randomized study design, comparing 0.05% cyclosporine versus placebo. The sample size of the...

  • Lutein, zeaxanthine, and AMD: Authors' response.
    Hugh R Taylor

    Dear Editor

    Regarding the comments by Beaumont and Kang to our letter "Does dietary lutein and zeaxanthin increase the risk of age-related macular degeneration?" (Vu et al., BJO 2006;90:389), we feel that a dual standard is used in this letter to accept or reject data. How many of the case-control studies or cohort studies (that rely on self reported data on both exposure and outcome) that are used to support the...

  • MRI has great potential to assist in diagnosis of giant cell arteritis
    Thorsten A. Bley


    With great interest we read the letter by Brannan et al, "The use of magnetic resonance imaging in the diagnosis of suspected giant cell arteritis" (BJO 2004;88:1595). The authors conclude that MRI scanning is unable to distinguish between a normal and an unaffected artery and that there is no potential for the use of MRI scanning without contrast enhancement in the evaluation of patients with giant cell art...

  • Overestimation of uncorrected refractive error in Singapore teenagers
    Michael S Lee

    Dear Editor:

    We read with interest the recent article by Ho and colleagues [1]. The authors present a study of teenagers who underwent visual acuity testing, noncycloplegic autorefraction, and habitual refraction. The authors define myopia as a spherical equivalent (SE) of at least -1.00 diopters (D).

    It has been reported that autorefraction (AR) can overestimate myopia in noncycloplegic pediatric pati...

  • Isotretinoin and night vision
    sreekumari pushpoth

    Dear Editor,

    We read Mollen et al's (1) article with interest where they have concluded that previous isotretinoin use does not cause a clinically significant reduction in night vision in most people and that the retinal toxic effects of isotretinoin may be measurable by electroretinography (ERG) and dark adaptation (DA). While the authors have successfully highlighted the importance of counselling patients for...

  • Non-arteritic anterior ischaemic optic neuropathy and sleep apnoea
    Aris Konstantopoulos

    Dear Sir

    We read with interest the article by Palombi et al discussing the association between non-arteritic anterior ischaemic optic neuropathy (NAION) and obstructive sleep apnoea (OSA). [1] OSA was found in 89% of patients with NAION. This finding may have significant implications on clinical practice and patient care, especially in view of the fact that 19 out of the 27 patients in the study required nCPAP trea...

  • National Patient Safety Agency Protocol for Pre-operative Site Marking
    Philip Alexander


    Fraser and Adams's commentary suggests that the most important method of reducing wrong site surgery is to have a consistent and robust protocol (1). They also give examples of numerous factors that disrupt the smooth running of the system and increase potential for harm. In March 2005, the National Patient Safety Agency produced a Patient Safety Alert in an attempt to standardise preoperative marking an...
