  • Sutureless surgery in Maharastra, India
    Jayant P Shah

    Dear Editor

    We have been conducting high volume cataract surgery (hospital-based with full fledged ophthalmic facilities) in rural parts of Maharastra state in India, conducting about 4000 to 5000 thousand sutureless cataract extractions with lens implantations in last 5 years.

    Patients with mature cataract with vision not more than finger counting at 5 feet are selected. They all undergo routine eye exams and...

  • 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...

  • Re: Surgery for glaucoma in the 21st century
    Andre Mermoud

    Dear Editor

    Regarding the editorial by Khaw et al.[1] we are surprised that after quite a few years now non- penetrating filtering surgery (NPFS) remains only partly understood by many ophthalmologists. There are at present two main NPFS: viscocanalostomy as described by Stegmann, in which outflow filtration is at least in theory not subconjunctival, and deep sclerectomy with or without an implant or even wi...

  • Reply to editorial "Surgery for Glaucoma in the 21st Century"
    Richard J. Fugo

    Dear Editor

    I found your editorial on glaucoma in the 21st century to be fascinating.[1] Not only did you give us insight as to where we are in the field, but you certainly give us provocative insight into where we might be headed in the pursuit of the perfect glaucoma procedure.

    I would like to state at the onset that I have a financial interest in product involved in this discussion, having develop...

  • Non-invasive volumetric blood flow measurement in the orbit
    Nemeth Janos

    Dear Editor

    We read with great interest the article of Orge and co-workers[1] who claim a first-ever solution to the problem of non-invasive volumetric blood flow measurement in the ophthalmic artery. This is a very important topic both from the clinical and scientific point of view, since blood supply is an important parameter for example in glaucoma studies. However, to date for the orbital circulation only the bl...

  • Temporal incision in all eyes using dominant hand
    Venkatesh Rengaraj MD

    Dear Editor

    2 We read with keen interest the paper by Kageyama et al,[1] which analyzed the results of performing phacoemulsification with dominant versus non-dominant hand. The results were also interesting; vitreous loss was higher with dominant hand group (5.9% vs.3.4%) and opposite in case of endothelial cell loss. Even though vitreous loss has been similar to a few other reports of conventional superior inc...

  • Economic Advantages of Immediate Sequential Phacoemulsification
    Venkatesh Rengaraj MD

    Dear Editor

    We read with interest the article on immediate sequential phacoemulsification (ISP) by Wertheim et al.[1] Bilateral intraocular surgery has been a controversial topic for ophthalmologist because of the risk of bilateral catastrophic complications such as endophthalmitis. Unilateral cataract surgery may result in anisometropia which can be debilitating for a person who could have been performing fine...

  • etiology of interstitial keratitis responding to acitretin?
    Mary J. van Schooneveld

    Dear Editor

    I read with interest your paper the effect of acitretin on interstitial keratitis. However, I am left with a few questions. First, you suggest the interstitial keratitis in your patient was due to tuberculosis, but you do not comment on diagnostics: was a PCR performed on aqueous fluid? was the button of the left eye in 1993 histologically examined? Secondly, on the photograph there seems to be a hypopyon p...

  • Author's reply
    Monique J. Cordonnier

    Dear Editor

    Of course you must proceed to a cycloplegic refraction, otherwise you cannot be sure that the refractive error is purely astigmatic. The sign of the astigmatism may also change after cycloplegia. Moreover, be cautious about the cylinder value given by the Retinomax if the spherical ametropia is high.[1]

    Reference

    (1) How accurate is the hand-held refractor Retinomax in measuring cyclople...

  • Non-penetrating gluacoma surgery
    Tarek M Shaarawy

    Dear Editor

    The authors of this article (Tan J C H, and Hitchings R. Non-penetrating glaucoma surgery: the state of play. Br J Ophthalmol 2001;85:234-237) should be commended on attempting to tackle this issue. Nevertheless we do feel that their fundamental points and principal arguments merit reconsideration.

    The authors state categorically that "long term outcomes do not exit for the newer...
