  • Re: Amblyopia: is visual loss permanent?
    Dear Editor,

    The paper by El Mallah, et al. [1], reporting visual recovery in the amblyopes after visual loss in the non-amblyopic eye brings new evidence for visual system plasticity extending beyond what was considered the critical period. Our observation of two patients presented below further supports it and suggests plasticity may be pharmacologically enhanced.

    A 22-year-old woman with strabismic amblyopia...

  • Atopy and keratoconus: a multivariate analysis

    Dear Editor

    We found that the reported incidence of approximately 1 per 2,000 (or 50 per 100,000) per year, and prevalence (54.5 per 100,000) of keratoconus reported by Bawazeer et al,[1] present some contradictions and formal imprecision.

    Incidence is a dynamic morbidity rate, which indicates the number of new cases occurring during a specified period of time, over the population at risk in the same per...

  • Transpupillary thermotherapy in choroidal neovascularization

    Dear Editor

    The recent article by Newsom et al.[1] on transpupillary thermotherapy (TTT) raises more questions than it is able to answer. Although TTT is definitely a method which seems to show a certain efficacy in occult choroidal neovascularization (CNV) and thus warrants further investigation, we must take issue with the authors' conclusions concerning its use in classic CNV.

    The authors state tha...

  • Re: Treatment of sagging eyelids caused by facial palsy

    Dear Editor

    I thank Van den Bosch for his interest in my paper[1] on the role of the suborbicularis oculi fat (SOOF) lift in the rehabilitation of patients with chronic facial palsy. The aim of my paper was to describe the lateral tarsal strip (LTS)[2,3] in conjunction with a SOOF lift in the correction of lower eyelid "sag" or paralytic ectropion. The use of this procedure was confined to patients in whom, pre...

  • Biometric aspects and comparison with published papers

    Editor,
    In the discussion Bechmann and colleagues mention the results of Ehlers et al[1] and compare them with the results of Whitacre et al[2] without regard for generally accepted principles of interpretation.[3] Some biometrical considerations will be found in the following. In figure 4 in the paper by Ehlers et al the correlation coefficient between the correction value and corneal thickness is 0.768...

  • Treatment of sagging eyelids caused by facial palsy

    Editor,
    This paper describes 9 consecutive patients suffering from sagging of the lower eyelid due to facial palsy, in whom lifting of the suborbicularis oculi fat (SOOF) was added to the usual treatment with the lateral tarsal strip procedure and, if indicated, medical canthal tightening. Based on observation of her results, the author concludes that SOOF-lifting both supports the elevation of the low...

  • Argon laser and trichiasis - a helpful tip

    Editor,
    Trichiasis is a posterior misdirection of eyelashes. Due to constant corneal irritation it can give rise to discomfort, recurrent infection, corneal ulceration and pannus formation. Several modalities of treatment exist which include epilation, electrolysis, cryotherapy and argon laser thermoablation.[1] [2] Argon laser offers the advantage of being a relatively simple, virtually painless met...

  • Impression cytology in the diagnosis of ocular surface squamous neoplasia

    Editor,
    It is pleasing to see Tole et al[1] having success with impression cytology (IC) in the diagnosis of ocular surface squamous neoplasia (OSSN) and we thank the authors for their acknowledgment of our work.

    We continue to use the small cellulose acetate strips because they offer greater sampling flexibility. However, the Biopore membrane could have practical advantages if samples are to be colle...

  • Inversed optokinetic nystagmus

    Editor,
    We read with interest the article by Valmaggia et al[1] who studied OKN in patients with macular degeneration. They noted abnormalities of OKN gain only in patients with large central scotomas. Therefore an intact macula seems not to be necessary for the generation of OKN. This implicitly suggests an important role of the peripheral retina in eliciting an OKN. In this context, it is interes...

  • TDLC in inflammatory glaucoma

    Editor,
    I read the article by Schlote et al with interest. The aim of their study was to determine the safety and effectiveness of transscleral diode laser cyclophotocoagulation (TDLC) in post inflammatory eyes with refractory glaucoma. In addition, the authors have rightly pointed out that management of inflammatory glaucoma is still a dilemma as many of the antiglaucoma drugs are either contraindica...
