  • Response to distal enlargement of the optic nerve sheath in the hyperacute stage of intracerebral haemorrhage
    Riccardo Moretti

    Dear Editor, we have read with great interest the article of Skoloudik and coworkers on the use of optic nerve ultrasonography in patients with intracranial hemorrhage (ICH). The primary goal of this study was to investigate the variations of the optic nerve sheath diameter (ONSD) early after the onset of ICH. The authors should be commended for pointing out our interest towards a new parameter (the relative difference be...

  • educational/motivational intervention and amblyopia treatment:
    professor viroj wiwanitkit

    Editor, I read the recent publication by Awan et al. with a great interest [1]. Awan et al. concluded that "As compliance has been identified as a major problem methods to improve amblyopia treatment are needed, possibly by using educational/motivational intervention [1]." Recently, Lee et al. proposed that "Poor compliance with occlusion therapy was less likely to achieve successful outcome [2]." Indeed, "how complianc...

  • Response to Outcomes of orbital blowout fracture surgery in children and adolescents
    Stephanie K West

    Dear Editor, We thank Authors S.C. Carroll et al for their interesting paper on the Outcomes of orbital blowout fracture surgery in children and adolescents.1 We agree that autonomic symptoms of nausea and vomiting should alert the clinician to the high likelihood of significant orbital trauma. This study shows that the overall outcomes for all patients under the age of 20 were good despite delays. However, this is a hete...

  • CUSUM for monitoring competency: Computer software is useful for bootstrapping and real time CUSUM plotting.
    Jacob M. Puliyel

    We congratulate Salowi and colleagues on their study of the use of CUSUM to monitor competency in cataract extraction (1). However there are two modifications that could make their system more responsive and reliable.

    Firstly the authors use a CUSUM chart that fluctuates on only one side of the zero line. Traditionally CUSUM charts fluctuate on both sides of the zero line (2,3). The consultant in their Figure 1...

  • Re:The Primary Eyecare Acute Referral Scheme, PEARS was introduced in Wales in in 2003. We welcome the paper by Sheen et al since this presents an opportunity for the scheme to be appraised and costed.
    Nicholas JL Sheen

    Authors response

    Dear Sir,

    One concept of the PEARS/ WEHE schemes was to increase equity of access to eye care services across Wales. Any successful scheme which achieves an increase in access will increase cost, at least in the short- term, but can prove to be more cost-effective since more expensive downstream-treatments are avoided as a result of earlier intervention and patient outcomes are likely...

    Simon Longstaff

    Sir,

    The Primary Eyecare Acute Referral Scheme, PEARS was introduced in Wales in in 2003. We welcome the paper by Sheen et al since this presents an opportunity for the scheme to be appraised and costed.

    The authors are open about the weaknesses of their study, such as the poor response rate to letters sent to GPs. However, there are still considerable uncertainties about the accuracy of the costings....

  • Post-operative pain after phacoemulsification
    Mohammad A. Khan

    Dear Editor,

    Sub-Tenon block is a safe, efficient and effective technique for delivering local anaesthesia for phacoemulsification cataract surgery.[1] Several studies have compared sub-Tenon's block with topical anaesthesia for intra-operative pain complications and the technique is found to be favourable.[2] We are not aware of any published study that has assessed post-operative pain (beyond 30 minutes post-...

  • Excision of periocular basal cell carcinoma
    Anju Kadyan DMI, MS, FRCS(Ed)

    Dear Editor, We read the paper by Chadha and Wright on small margin excision of periocular basal cell carcinoma (BCC) with interest. (1)The authors justify the use of small margins, without margin control (excision and closure without confirmation of histologically clear margins) by their low recurrence rates over a follow up period ranging from 37-59 months.

    There has been extensive debate on the ideal approach to...

  • "Authors' Response"
    Kazuaki Nishijima
    Thank you for your comment. In our manuscript, we did not use the mean and the standard deviation but used each patient's raw data for the analyses. Further, as written in the methods section, we only used unpaired Student's t test (parametric test) for the comparison between the two groups and paired Student's t test (parametric test) for the comparison between the baseline and each follow-up point.

  • Response to RCT trial of PST as an adjuvant to PRP in Diabetic Retinopathy
    Dr Kumar Sambhav

    Dear editor,

    We have read with great interest the article by Unoki N et al Randomised controlled clinical trial of sub-tenon triamcinolone as an adjunct to panretinal photocoagulation for the treatment of diabetic retinopathy 1. We wish to make few comments. The p value of the primary outcome as documented is 0.04. But if calculated from the results documented, applying parametric tests as used in the study it co...
