  • The social impact of visual impairment
    Geraint P Williams

    Dear Editor

    We read with interest the extended report by Hassell and colleagues [1] demonstrating the adverse effect of quality of life in mild visual impairment (<6/12) and worse. Their demonstration of the impact of Age Related Macular Degeneration (AMD) on quality of life indices is an important illustration of the difficulties experienced by the visually impaired.

    We have reported a similar exper...

  • Bacterial co-infection in mycotic keratitis in India - a tertiary eye care centre experience
    Sujith Vengayil

    Dear Editor,

    We read with great interest the article published by Pate JC (1) in your journal and the editorial (2), regarding polymicrobial infection of cornea. Our centre is a tertiary level eye care centre in northern India and also the apex centre for eye care of the country. We, in our country come across a large number of fungal keratitis cases compared to that reported in western studies. Though the author...

  • Topical use of cyclosporine A
    Antonio G Secchi

    Dear Editor,

    I have just finished reading the interesting paper by Daniell et al and, being one of the first authors (Secchi AG et al, AJO, 1990, 110, 137- 42) to become interested in the topical use of Cyclosporine A in "allergic" conditions concerning the ocular surface, I would like to make a few comments - based above all on a 20-year experience in the treatment of vernal keratoconjunctivitis (VKC) with topi...

  • Scleral tunnel for Molteno implant insertion
    Sunil P Deokule

    Dear Editor,

    We would like to commend authors for describing a modification to surgical technique for insertion of Molteno tube implant that eliminates the need for a donor patch scleral graft.1 The purpose of this modification is laudable however we do envisage few surgical difficulties with this modification. Firstly the creation of scleral tunnel using a curved 20 gauge microvitreoretinal (MVR) blade creat...

  • Re: Management of subretinal macular haemorrhage by direct administration of tPA
    H. K Kang

    Dear Sir,

     

    We read with great interest the report by Singh et al,1 describing the management of subretinal macular haemorrhage by vitrectomy, subretinal injection of tissue plasminogen activator (tPA) and pneumatic tamponade. Our experience with this techinque has also been positive, and this approa...

  • 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...
