  • 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...

  • Vision screening in a primary care setting
    Alexander J Silvester

    Dear editor,

    I was interested to read the editorial on vision screening by Evans, Smeeth and Fletcher [1]. I share their concern that, despite the availability of free eye tests for the older population, over 50% of vision impairment is due to easily correctable conditions.

    I recently audited an elderly person health check; an annual assessment of the medical, social, and physical needs of all patie...

  • Estimation for trachoma prevalence in Egypt
    Gamal Ezz Elarab

    We read with great interest the article by Mariotti et al. estimating the global prevalence of trachoma. For the country of Egypt, the article refers only to the published survey in Menofiya Governorate in the Nile Delta, suggesting that only this single governorate is endemic for trachoma. This is far from the case, however, as two other studies shed light on trachoma in other areas of Egypt. Both studies were presen...
