  • Microbial contamination of preservative free eye drops
    Arijit Mitra

    Dear Editor,

    I applaud the authors for attempting to address the issue of microbial contamination of preservative free (PF) eye drops in multiple application containers but wish to highlight a few points.

    Although informed consent have been obtained from patients prior to analysing their eye drops, it is surprising that ethical committee approval was not sought before starting the study.

  • Contamination of preservative free eye drops
    Sher A Aslam

    Dear Editor,

    We read with interest the article by Rahman and coauthors but wish to highlight a number of points.

    With regards to the aim of the study which was to evaluate and compare microbial contamination arising after 3 days and 7 days use of preservative free eye drops, this was not apparent from the study design. There was no stratification of data according to these two time periods; it would be i...

  • Authors' response
    Luba Robman

    Dear Editor,

    We were interested to see the letter by Mitchell et al, written in response to our earlier publication [1].

    Mitchell and co-workers raise several points, the first of which is the way one handles missing data. AMD can be assessed either clinically or photographically. Rather than throw away data and run the potential of bias by excluding patients who did not have a retinal photograph, we c...

  • Re: Unilateral vision impairment
    Kurt Simons

    Dear Editor,

    There appear to be a number of questions with the regard to the findings reported by Hrisos et al:[1]

    1. The study could not distinguish between amblyopia and other forms of “unilateral visual impairment,” but groups all cases together. This limits the study’s utility in demonstrating the functional effects of amblyopia.

    2. The paper describes its acuity testing only as a "Snell...

    Dear Editor,

    We appreciate a response to our study from Dr Landers et al. They reported that five out of ten eyes with abnormal result of Frequency Doubling Perimetry (FDP) and normal result of Achromatic Automated Perimetry (AAP) showed abnormal result on AAP four years later.[1] It was our mistake that we referred their study as a cross-sectional study in our paper. We apologize to them that we should have referr...

  • Corneal calcification associated with the use of topical phosphate containing preparation
    Amit V Datta

    Dear Editor,

    We read with great interest the article by Bernauer et al [1] on the use hyaluronate artificial tear formulation �Hylo-Comod� favours the formation of corneal calcification related to the phosphate content of eye medications and frequent instillation. We agree with their conclusion and would like to highlight that in the setting of dry chronically inflamed eyes phosphate containing topical preparati...

  • Re: The role of Mohs excision in periocular basal cell carcinoma
    S Hamada

    Dear Editor,

    We thank Barnes et al for their interest in our study and for affording us the opportunity to correct some misinterpretations that others may also have made regarding our paper.

    We agree entirely that histological examination of the complete excision surface as suggested by Mohs would be the ideal one should aim at and that it would be superior to conventional bread loaf histological sect...

    Wolfgang Bernauer

    Dear Editor,

    Thank you for writing and giving us the opportunity to further comment on our case series and investigations. We wish to put several misquotations right, respond to the accusation of inappropriate dosage, comment on the declaration of ingredients, explain our case description and substantiate the necessity to publish this case series.

    Please note that we described five and not six cases. The...

  • Surgical characteristics of the retinal inner limiting membrane
    Thomas Theelen

    Dear Editor,

    In a recent issue of the Journal Steven et al. describe secondary retinal holes after removal of the inner limiting membrane (ILM) [1]. We consider this a key retinal publication and therefore wish to strengthen the importance of the authors' findings for modern surgery of the vitreoretinal interface.

    Interestingly, the paper included only patients with macular puckers and cystoid macular oed...
