  • Vitrectomy with and without scleral buckle for inferior retinal detachment
    Dennis S.C. Lam

    Dear Editor

    In the article presented by Wickham and associates,[1] the authors compared vitrectomy and gas for treating inferior break retinal detachments with vitrectomy, gas and scleral buckle. The study showed no significant difference in the final outcome between the two groups. While vitrectomy and gas for inferior break retinal detachments appears promising, there are several issues that we would like to ra...

  • Tight necktie, intraocular pressure and intracranial pressure
    Jost B. Jonas

    Dear Editor

    I would like to congratulate Theelen et al for their recent article on impact factors on intraocular pressure measurements in healthy subjects [1], and I would like to add a thought. As Theelen and colleagues point out with reference to the literature [2,3], increased pressure in the jugular vein leads to increased brain pressure, and by an increase in the episcleral venous pressure, to an elev...

  • Inferior retinal detachment or not ?
    Jean-Claude Quintyn

    Dear Editor, We were highly interested by Sharma et al's paper on inferior-tear retinal detachment (RD) and we would like to make a few remarks. Is there any significant difference between phakic and pseudophakic patients ? When comparing the two techniques, it is worth reminding that vitrectomy will systematically induce cataract within a few years, which will imply secondary surgery. This will considerably increa...

  • Mitomycin C for pterygium: long term evaluation
    Dennis S.C. Lam

    Dear Editor

    We read with interest for the article by Raiskup et al. on the long term evaluation on mitomycin C (MMC) for pterygium.[1] It seems that the usage MMC in pterygium surgery is relatively safe in the long term.

    Overdosge of MMC eyedrops may be associated with potential serous side effects such as corneal perforation.[2] In this regards, we would like to point out a major typo in the Abstr...

  • Risk Stratification For Cataract Surgery
    Dany M Najjar

    Dear Editor

    We read with interest the article by Muhtaseb et al. on the development of a system for preoperative stratification of cataract patients according to their risk of intraoperative complications. [1] In their article the authors have analyzed 1441 cataract surgeries in order to determine factors that would increase the risk of surgical complications.

    We have previously described a si...

  • Cystoid macular oedema with trypan blue use
    Dennis S.C. Lam

    Dear Editor

    We read with interest the article by Gouws et al.[1] on the apparent increased incidence of cystoid macular oedema (CMO) in phacoemulsification patients when trypan blue was used to stain the anterior capsule.

    Trypan blue was commonly used in both anterior and posterior segment surgeries.[2-4] If trypan blue does cause macular toxicity, its risks should theoretically be higher when used...

  • Regarding postoperative trabeculectomy leakage.
    Tom G Askew

    Dear Editor

    We read with interest the report by Henderson et al.[1] The title of the paper includes the word "early" and the median time to leak is 3.5 days, but the range of time taken for bleb leakage to develop extends to 408 days postoperatively. We do not think this is early nor a postoperative complication.

    Wound leakage complicates the management of trabeculectomy: some eyes develop anter...

  • Response to Professor Bajaj
    A Jane Dickinson

    Dear Editor

    We read with interest the comments of Professor Bajaj and colleagues and wish to respond to the points raised as follows.

    Firstly, we are in complete agreement that the horizontal laxity of the eyelid should be evaluated pre-operatively and indeed this was done. This led to the necessity for 9 of the patients (28%) to undergo primary adjunctive procedures as stated in the article. Indeed 1...

  • Modification of ocular surface burns
    Shabbir Harun

    Dear Editor

    In his second eLetter (1), Dua continues his criticism of our proposed modification of the classification of ocular surface burns(2) but once again fails to understand our motivation, which is to simplify the grading of such injuries in the light of recent advances in the management of ocular surface disease (3-6). The result is a modification of a well established classification, which is easily reme...

  • Charles Bonnet Syndrome in patients with glaucoma and good acuity
    Stephen A Madill

    Dear Editor

    We read with interest the paper by Tan et al. [1] on Charles Bonnet Syndrome (CBS) in Asian patients. Their finding of a lower CBS prevalence than European or North American surveys demands further investigation, although this may reflect the stringent criteria of hallucination complexity they used in making the diagnosis (thus excluding the commonest CBS hallucinations of coloured blobs and gri...
