  • Response to a reduced logMAR chart for clinical practice

    A most outstanding research article that merits full praise to all of the authers.One of the best and furthermore the most useful article that I have read in a very long time.

  • Comments: A new colour vision arrangement test
    Dear Editor,

    I refer to the interesting article by Maar et al [1] published in Br J Ophthalmol 2001; 85: 47-51. The authors should be congratulated for presenting a new method of screening for diabetic macular oedema, however the paper contains some statistical errors, and I believe the results can be interpreted in other ways.

    Firstly, there are some internal inconsistencies with some of the results reported in the...

  • Further pathophysiological insights into age-related macular degeneration
    Dear Editor

    We read with great interest the excellent Editorial by Ciulla [1] which describes pathophysiological paradigms for age related macular degeneration (ARMD) and the development of choroidal neovascular membranes (CNVM). We were particularly pleased to note that Ciulla [1] considered that 'whatever the initial stimulus for CNVM formation, it is clear that angiogenic growth factors are ultimately involved.' Furtherm...

  • IOL implantation with ACM
    Dear Editor,

    I have two points to make about this article:

    1. Adhesion to the capsule works even during implantation of IOLs. As the acrylate material IOLs seem to have a higher adhesion tendency they require a lubricant viscoelastic material during rotation and positioning. This is why it is more difficult to rotate an acrylate IOL while using an AC maintainer and no viscoelastics. Silicone and PMMA IOLs do not...

  • Re: Amblyopia: is visual loss permanent?
    Dear Editor,

    The paper by El Mallah, et al. [1], reporting visual recovery in the amblyopes after visual loss in the non-amblyopic eye brings new evidence for visual system plasticity extending beyond what was considered the critical period. Our observation of two patients presented below further supports it and suggests plasticity may be pharmacologically enhanced.

    A 22-year-old woman with strabismic amblyopia...

  • Atopy and keratoconus: a multivariate analysis

    Dear Editor

    We found that the reported incidence of approximately 1 per 2,000 (or 50 per 100,000) per year, and prevalence (54.5 per 100,000) of keratoconus reported by Bawazeer et al,[1] present some contradictions and formal imprecision.

    Incidence is a dynamic morbidity rate, which indicates the number of new cases occurring during a specified period of time, over the population at risk in the same per...

  • Transpupillary thermotherapy in choroidal neovascularization

    Dear Editor

    The recent article by Newsom et al.[1] on transpupillary thermotherapy (TTT) raises more questions than it is able to answer. Although TTT is definitely a method which seems to show a certain efficacy in occult choroidal neovascularization (CNV) and thus warrants further investigation, we must take issue with the authors' conclusions concerning its use in classic CNV.

    The authors state tha...

  • Re: Treatment of sagging eyelids caused by facial palsy

    Dear Editor

    I thank Van den Bosch for his interest in my paper[1] on the role of the suborbicularis oculi fat (SOOF) lift in the rehabilitation of patients with chronic facial palsy. The aim of my paper was to describe the lateral tarsal strip (LTS)[2,3] in conjunction with a SOOF lift in the correction of lower eyelid "sag" or paralytic ectropion. The use of this procedure was confined to patients in whom, pre...

  • Biometric aspects and comparison with published papers

    Editor,
    In the discussion Bechmann and colleagues mention the results of Ehlers et al[1] and compare them with the results of Whitacre et al[2] without regard for generally accepted principles of interpretation.[3] Some biometrical considerations will be found in the following. In figure 4 in the paper by Ehlers et al the correlation coefficient between the correction value and corneal thickness is 0.768...

  • Treatment of sagging eyelids caused by facial palsy

    Editor,
    This paper describes 9 consecutive patients suffering from sagging of the lower eyelid due to facial palsy, in whom lifting of the suborbicularis oculi fat (SOOF) was added to the usual treatment with the lateral tarsal strip procedure and, if indicated, medical canthal tightening. Based on observation of her results, the author concludes that SOOF-lifting both supports the elevation of the low...
