  • Keratectasia after PTK
    Simon J Dean
    Dear Editor,

    Miyata and colleagues have elegantly described an interesting and rare complication of phototherapeutic keratectomy (PTK) in their recent report of an unusual case of keratectasia after PTK. The hypothesis that risk of ectasia is proportional to residual stromal base, or depth of ablation, fits with the assumed biomechanical aetiology of this recently reported complication of laser refractive surgery. The gene...

  • About a series of xeroderma pigmentosum in nothern Nigeria
    Michel Moussala
    Dear Editor,

    This series is certainly the largest ever reported in west Africa [1]. However, it is worth noting that Xeroderma Pigmentosum (XP) has already been described in two Mauritanian half cousins in France [2]. Two isolated cases have been reported in Senegal and Cameroon, respectively [3,4]. The skin of black people, rich in melanin provides some protection from the oncogenic effects of ultraviolet rays. It is possib...

  • Amniotic membrane transplantation in acute ocular burns
    Anita Panda
    Dear Editor

    We read with interest the article titled "Failure of amniotic membrane transplantation (AMT) in the treatment of acute ocular burns" by Joseph et al[1]. It is to be appreciated that they have come forward to report the negative results of their study along with the need of an upgraded classification for the chemical burn. The authors must be congratulated for highlighting the pitfalls of the AMT in acute cases w...

  • Association of latanoprost with recurrent herpes simplex dendritic keratitis
    Dear Editor,

    I read with interest the article by Ekatomatis [1] on latanoprost treatment for primary open angle glaucoma causing herpes simplex dendritic keratitis. He should be applauded for reporting a serious side effect of latanoprost. His assertion however that latanoprost has been known to have almost no serious side effects is not entirely accurate. In fact, Wand et al [2] reported three patients who developed herp...

  • Queries on latanaprost
    Dear Editor

    The study is a good comparison of the two medications. I have a few queries for the authors:

    1) Why is latanoprost causing an increase in iris pigmentation; is that not a cause for concern and should this serious side effect not be investigated more fully?

    2) Latanoprost increases uveoscleral outflow; does it bypass the trabecular meshwork or is it causing any blockage in aqueous outflow from th...

  • Transpupillary silicone oil removal combined with phacoemulsification
    Dear Editor

    We read with interest the article entitled 'Combined phacoemulsification and transpupillary drainage of silicone oil: results and complications'[1]. We similarly removed silicone oil through the posterior capsulorhexis along with phacoemulsification[2]. We used an inferotemporal infusion cannula in the pars plana region in all except the first two eyes where intraoperative choroidal detachment ocurred. Similar in...

  • Re: IOP measurement and central corneal thickness - authors' reply
    Dear Editor

    In reply to the comments of Stodtmeister and colleagues [1] on our recent paper [2], we won´t argue the correlation between central corneal thickness (CCT) and intraocular pressure (IOP), but we mistrust the clinical application of correcting factors. Stodtmeister et al compare our study to that of Ehlers et al [3] which is often cited to prove an influence of corneal thickness on applanatory measurement.

  • IOP measurement and central corneal thickness
    Dear Editor

    [Please note that the tables for this letter will be available in the December issue of BJO.]

    In the recent paper by Feltgen et al [1], the intraocular pressure was measured by Goldmann applanation tonometry and by using a cannula inserted into the anterior chamber connected with a pressure transducer. Thus the measurement took place omitting a possible influence of the cornea on the result. Marx et al[...

  • Surgical approach to conjunctival carcinoma
    Dear Editor,

    The report of Mauriello et al. "Adenoid squamous carcinoma of the conjunctiva -- a clinicopathologic study of 14 cases" [1] has profoundly impressed us as plastic and reconstructive surgeons who encounter the problem of exenteration or enucleation. Facial plastic surgeons are most frequently asked to reconstruct the exenterated orbit, but also often meet the patient before surgery when the decision for exentera...

  • Duration of alcohol exposure during laser subepithelial keratomileusis (LASEK)
    Dear Editor,

    We read with interest the excellent article by Shah et al. [1] The authors compared the outcomes of epithelial debridement for photorefractive keratectomy (PRK) with those of epithelial flap for PRK. They used 20% ethanol for 30 seconds and 45 seconds for the debridement and flap techniques, respectively. They observed that epithelial flap resulted in faster visual rehabilitation and reduced haze. We have ob...
