  • Do retinopathy signs in non-diabetic individuals predict the subsequent risk of diabetes?
    Paul Mitchell

    Dear Editor,

    We read with interest the article by Wong T.Y. et al[1], which studied a non-diabetic population consisting of 7992 people aged 49-73 years. Non-mydriatic retinal photographs of one eye were taken and graded for retinopathy lesions using to standardised protocols. Surprisingly, the presence of typical retinopathy lesions (microaneurysms or retinal haemorrhages) in persons without diabetes did not signi...

  • Impression Cytology: Implications for ocular surface squamous neoplasia (OSSN)
    Charles McGhee

    Dear Editor,

    We read with great interest, Singh et. al.’s[1] perspective on impression cytology and its uses in diagnosing ocular surface pathology. The known higher exposure to UV radiation in both Australia and New Zealand, and the increased incidence of ocular surface squamous neoplasia (OSSN) in Australia,[2][3] recently led us to audit the incidence of OSSN in conjunctival biopsies in New Zealand over a 6...

  • Detecting early visual field loss with Frequency Doubling Perimetry
    John A Landers

    Dear Editor,

    We congratulate Kogure et al,[1] on a well designed longitudinal study, which confirms the suspicions of many earlier investigators, who conjectured that Frequency Doubling Perimetry (FDP) may be able to detect visual field loss earlier than Achromatic Automated Perimetry (AAP) based on cross-sectional data. In their text they refer to our longitudinal study[2] as a cross-sectional one and go on to s...

  • Reply from Pfizer
    Rachel E. Sobel

    Dear Editor,

    RE: Non-arteritic anterior ischaemic optic neuropathy and the treatment of erectile dysfunction.

    McGwin et al.[1] suggest that treatment of erectile dysfunction with sildenafil (Viagra®) or tadalafil (Cialis®), two phosphodiesterase inhibitors (PDE5-I), may increase the odds of non-arteritic anterior ischaemic optic neuropathy (NAION) in men with a history of myocardial infarction (MI...

  • Quality of life after vitreoretinal surgery for epiretinal membranes
    Christoph Hirneiss, MD

    Dear Editor,

    We congratulate the authors Ghazi-Nouri et al. to their recently published study “Visual function and quality of life following vitrectomy and epiretinal peel surgery”. It mainly confirms our results on a very similar consecutive cohort of 20 patients followed for three months which was published August 2005 in the Medline indexed German “Ophthalmologe” [1] and therefore represents the first paper...

  • Polymicrobial keratitis
    Uma Sridhar

    Dear Editor,

    We read with great interest the clinical report by Pate et al. in which bacterial conifection in keratomycosis was reported by smear, culture or both. We have seen in our own practice in a series of 110 cases of infectious keratitis (unpublished data) between year 2001-2005, six cases of bacterial co infection in keratomycosis. Five of them were smear positive and one case was only culture positive...

  • Clinical evaluation of fungal keratitis in developing nations
    Prashant Garg

    Dear Editor,

    We read with great interest the article titled 'Characteristic clinical features as an aid to the diagnosis of suppurative keratitis caused by filamentous fungi' by Thomas and associates1. We would like to congratulate the authors on this attempt to validate the signs of fungal keratitis, which would be helpful to the ophthalmologists of developing nations. We would like to make following comments:...

  • Phosphate on the cornea: The dose makes the poison.
    Norbert F. Schrage

    Dear Editor,

    The article by Bernauer et al. takes a new focus on the topic of corneal calcification related to the phosphate content of eye medications. This topic has been addressed previously by our group, first with the observation in glaucoma patients published by Huige et al. (1) then on the normal eye (2), and finally on patients with eye burns receiving phosphate buffer treatment(3). Other reports of non ph...

  • The role of Mohs excision in periocular basal cell carcinoma
    Eric A Barnes

    Dear Editor,

    We read with interest the paper by Hamada et al 1, which draws a number of conclusions from a five year follow up study of 69 periocular BCCs treated by conventional surgery, and in particular suggests that there is no place for Mohs micrographic surgery (MMS) in patients with periocular BCCs. MMS is the serial saucerisation excision with mapped horizontal tissue sections examining 100% of the surg...
