  • Deep lamellar keratoplasty by deep parenchyma detachment from the corneal limbs
    Marco Nardi

    Dear Editor,

    We read with great interest the paper by Senoo et al1 and we would like to draw your attention to a complication of the approach described. Some years ago, relying on our experience in deep sclerectomy, we tried a similar approach in two cases: we first performed a double scleral flap exposing Descemet membrane at limbus and then started the dissection. Although in both cases we had a good exposure of D...

  • Retroauricular grafts for exposed hydroxyapatite implants
    Thomas C. Naugle

    Dear Editor,

    We want to congratulate Drs. S.L. Liao, et al., on their excellent paper entitled "Surgical coverage of exposed hydroxyapatite implant with retroauricular myoperiosteal graft". 1 In the paper they described "a newly developed technique with an autogenous retroauricular myoperiosteal graft" to repair defects with exposed hydroxyapatite implants.

    However, they did not mention our retrospect...

  • Intraocular pressure, systemic blood pressure, and headache: occult pathophysiological link?
    Vinod K Gupta

    Dear Editor,

    Klein and colleagues show a significant correlation between blood pressure – both systolic and diastolic – and intraocular pressure (IOP).[1] Law et al. recently showed that blood pressure lowering drugs prevent a significant proportion of headaches; however, the causal relation between hypertension and headache – whether migrainous or non- migrainous -- remains ambiguous.[2] In the absence of a clear...

  • Learning with a lazy eye – a potential treatment for amblyopia
    Ben Webb

    Dear Editor,

    In a thought-provoking editorial in BJO entitled “Why is the amblyopic eye unstable?” C. Hoyt raised two very important issues relating to the treatment of human amblyopia. First, there is currently no effective alternative to occlusion therapy for treating amblyopia. Second, there is considerable “slippage” of visual acuity after cessation of occlusion therapy. Our sole purpose in responding to this...

  • The subarachnoid space of the optic nerve and visual loss in papilledema
    Sherif AK Amer

    Dear Editor,

    I read with great interest your extremely valuable article. I have been working in the field of PTC and optic nerve sheath decompression for about 12 years now and my clinical experience very much supports the findings in your work. There are variable degrees of papilledema in the same patient with the same level ICP and variable responses of patients to medical therapies decreasing the ICP, with some p...

  • Authors' Reply
    Simon K Law

    Dear Editor,

    We thank Drs. Tsai et al. for their interest in our article and for the opportunity to clarify the data of our study. Drs. Tsai et al. correctly point out that intraocular pressures (IOP), axial lengths (AL), corneal curvatures, and refractive errors change overtime following glaucoma surgery. The purpose of our study was not to follow the changes of ocular dimensions after combined cataract operatio...

  • Short and long-term effect of combined cataract and glaucoma surgery with MMC on ocular dimensions
    Chieh-Chih Tsai

    Dear Editor

    Law and co-authors have contributed valuable data on the effect of combined cataract surgery and trabeculectomy with mitomycin C (MMC) on ocular dimensions. [1] While it is unclear from the report whether all patients' data were collected at the same interval postoperatively and when the postoperative data were collected. As we know, the change in intraocular pressure, axial length (AL), and corneal cu...

  • Intraocular pressure changes in the contralateral eye after trabeculectomy with mitomycin C
    Dexter Y.L. Leung

    Dear Editor

    We read with great interest the article by Vysniauskiene et al.1 Their efforts in evaluating the intraocular pressure (IOP) changes of the contralateral eyes after trabeculectomy with mitomycin C (MMC) is appreciated. They concluded that a month after trabeculectomy, the mean IOP in contralateral eyes decreased. Of note, among the 24 fellow eyes in the study, 11 (45.8%) had topical ocular hyp...

  • Identifying Troxler
    Hans U. Iselin

    Dear Editor,

    I should like to congratulate the authors for the article citing the original publication on peripheral fading by Troxler (1804). However, as editor of the website on the work of the Swiss philosopher Ignaz Paul Vital Troxler (1780-1866) who started as physician and ophthalmologist before engaging in research on anthropological and political subjects, I regret that after 201 years, the publication of 18...

  • Ethnic and cultural variation in preference based (utility) measures
    Steven M Kymes

    Dear Editor,

    We read with interest the article by Gupta and colleagues describing their findings in an investigation of the utility loss associated with glaucoma. When considered in light of previous investigations this work makes an important contribution to our limited understanding of the influence of culture, socio-economic status, and ethnic background on health state preference. It is particularly gratifying...
