  • Partial flaps during LASIK
    Sumith Perera

    Dear Editor

    I read this article with interest.[1] Here, the authors suggest that the evaluation of the posterior corneal surface topographic changes after partial flaps without ablation may help us to know the contribution of the flap to the corneal elasticity and the increase in posterior corneal elevation following LASIK. However, I would like to point out that there are some very important differences between a...

  • A Perspective on Porous Polyethylene Lower Lid Spacers
    Mandeep S. Bajaj

    Dear Editor

    We read with interest the article on the use of Medpor lower eyelid spacers by Tan et al. [1]. The article critically evaluates the utility of this type of a spacer for retraction of the lower lid. We would like to raise a few pertinent issues which may assist in a better understanding of this challenging entity.

    In this article, the authors have not included the assessment of horizontal lid...

  • Experience from the Kikuyu Eye Unit in Nairobi

    Editor,
    I have visited the Kikuyu Eye Unit near Nairobi on a yearly basis since 1992, and have witnessed at first hand both there and in Somalia the enormous burden of poverty and ill health described and quantified in the editorial. What strikes me very forcibly is the sheer number of hugely disadvantaged people. This, and the distressing and widening disparity in health and income between these peopl...

  • Staining of the ILM in macular surgery
    Arnd Gandorfer

    Dear Editor

    We read with interest the article by Dr Li and colleagues about trypan blue staining of the vitreomacular interface during vitrectomy [1]

    We congratulate the authors on their work. In particular, we appreciate their critical approach of testing trypan blue for staining of the internal limiting membrane (ILM) and epiretinal membrane (ERM) as well as their comments on potential untowards effect...

  • Subjective evaluation of GDX printout detects asymmetric glaucoma
    Paul J Harasymowycz

    Dear Editor

    Recently, Munkwitz et al. reported excellent sensitivities and specificities of scanning laser polarimetry in detecting glaucoma when printouts were subjectively evaluated by experts having at least nine years experience with the device [1].

    The authors clearly defined a major difference with previously published studies, in that they evaluated GDx printouts of both eyes, although 23 of the...

  • Changing thresholds for cataract surgery

    Editor,
    We congratulate Hugh Taylor on his editorial in which he discusses the volume of cataract surgery which needs to be done. We were particularly interested by his calculations drawing attention to the effect of changing the visual threshold at which the decision to undertake cataract surgery is made.

    We have reviewed a series of eight audits of cataract surgery to determine the visual acuities a...

  • Re: Non-penetrating gluacoma surgery
    Roger A Hitchings

    Dear Editor

    We thank Drs Sharawary and Mermoud for their interest in our article [1] and respect their observations. They have made significant contributions to our understanding of non penetrating surgery in the treatment of chronic open angle glaucoma.

    With any new surgical technique information changes rapidly, and much new information has appeared since our article was written. The authors note current li...

  • Possible error in Venn Diagram
    Krishnappa C Madhusudhana

    Dear Editor

    We read the interesting article by L Wickham and associates, “Vitrectomy and gas for inferior break retinal detachments: are the results comparable to vitrectomy, gas and scleral buckle?” [1]. They have compared the results of vitrectomy and gas without scleral buckle (Group A) with, vitrectomy and gas with scleral buckle (Group B) for inferior break retinal detachments. We would like to point out to a...

  • Irradiation for reccurent pterygia

    Editor
    The article by Forbes et al on cheek mucosa is indeed interesting and helpful in cases of reccurent pterygia, but as they have given irradiation to cases after surgery it becomes a bias as to how much better is cheek mucosa compared with conjunctiva autograft.

    Secondly, have they considered the use of buccal mucosa for the same as cheek mucosa is more difficult to harvest although I agr...

  • 'Same day' bilateral cataract surgery
    William C. Caccamise Sr, MD

    Dear Editor

    Dr Johansson's thorough and well-written article concerning 'same day' bilateral cataract surgery brought home keen memories and stirred up thoughts of my own experience with this approach to certain patients legally blind due to cataracts.

    Periodically from 1951 through 1968, I was the Eye Surgeon-in-Charge of the then modern one hundred bed Kurji (Patna, Bihar, India) Holy Family Hospital Eye Cli...
