  • 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

    Sir,

    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

    Sir

    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...

  • Eye growth and refraction in preterms with and without retinal ablation therapy for ROP
    Hans C Fledelius

    Dear Editor,

    I can join the editorial appreciation of Axer-Siegel and coworker's recent article,1 as expressed by O'Keefe and Kirwan.2 In an experimental set-up the authors studied the effects of cryo- vs. diode laser application on the axial eye growth in 6-week-old rabbits. The induced eye wall trauma stimulated growth, of both anterior and posterior eye segment. This can be compared to the axial elongation...

  • IVTA and glaucoma: Brazil report
    Daniel Vítor Vasconcelos-Santos

    Dear Editor,

    We read with interest Rhee and co-workers' paper on intra-ocular pressure (IOP) alterations following intravitreal triamcinolone acetonide (IVTA) injection.[1] They presented the largest published patient series with the 4mg dose of IVTA (570 eyes of 536 patients). Furthermore, their comprehensive analysis concerning multiple criteria of IOP elevation (>5mmHg, >10mmHg and 30% increase from th...

  • Patient safety and ophthalmic surgery marking - which side are you on?
    Mary Milner White

    Dear Editor,

    We read with interest the paper by Fraser and Adams[1], which suggested many reasons for the wrong site surgery and also suggested ways of preventing it. We carried out semi-structured interviews of ophthalmic surgeons (Consultants and Specialist registrar) throughout Scotland by telephone on their current practices and attitudes relating to preventing wrong side surgery in ophthalmology and describe...
