  • 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...

  • Increasing the efficiency of Ophthalmic Care for all patients during Ramadan
    Rehna Khan

    Dear Editor

    Ramadan (the month of fasting for muslims) is approaching at the end of August 2009. As ophthalmologists in a centre with a large muslim population we read Kumar and Jivan's study with interest [1].

    We agree that poor compliance with treatment can be improved with patient education. A major proportion of chronic ophthalmological disease monitoring is for glaucoma, first line treatment for which...

(19 November 2008). We agree that a child vision screening tool that could be used effectively with minimal input from healthcare personnel would be desirable.

  • Plus lenses?
    Bernard L Cohen

    Dear Editor

    Out of ignorance, I am surprised that the lenses in a stereoscope should be described as "plus" lenses. They may be so, but I would have expected the more important property to be prism, to aid superimposition of the paired images.

    Please clarify the optics involved.


  • Authors' Response
    Susanne Binder

    Dear editor,

    We would like to give a response to the letter of Dr. Anshuman Sinha concerning our article "23 Gauge versus 20 Gauge System for Pars Plana Vitrectomy: A Prospective Randomized Clinical Trial".

    For analysis of postoperative pain we used a simplified verbal rating scale (ranging from 0, meaning no pain, to 3, meaning severe pain). The standardized verbal rating scale reaches from 0 (no pain) to...
