  • Normal Tension Glaucoma
    Michael C Brodsky

    Dear Editor,

    I enjoyed the recent study by Ogata et al. in which they attempted to assess the interrelationship between intracranial vascular compression of the optic nerves and normal tension glaucoma [1]. Coronal magnetic resonance images of the optic nerves were used to assess the degree of compression of the intracranial optic nerves and the supraclinoid internal carotid arteries. Compression of an optic nerv...

  • TTT: local light absorption and heat convection vs. heat conduction
    Martin A. Mainster

    Dear Editor,

    Drs. Miura, Nishiwaki and co-authors have contributed valuable experimental data on transpupillary thermotherapy (TTT) for choroidal neovascularization (CNV) in a rat model [1]. In their scholarly discussion section, they speculate that the variability in power settings they encountered in heating experimental CNV may be due to a “variation of heat conduction in experimental CNV” [1]. There are more p...

  • Smouldering ROP: a new variant?
    Vasumathy Vedantham

    Dear Editor,

    We read with interest the article on variations in the morphology of retinopathy of prematurity (ROP) [1]. We found the mention of a poorly developed capillary bed present in an already vascularised retina particularly interesting. We have noted a similar case that might corroborate this finding.

    A male infant of birth weight 1700 gms, 34 weeks gestational age was examined at 37 weeks post-...

  • Pre-operative videotape sessions and patient satisfaction with cataract surgery
    Kenneth SC Yuen

    Dear Editor,

    We read with interest the article ‘Randomised controlled trial of preoperative information to improve satisfaction with cataract surgery’ by Pager [1]. The study showed that a preoperative videotape session describing the experience of day-stay cataract surgery resulted in significant increase in overall satisfaction during the immediate postoperative period.

    Patient satisfaction has drawn...

  • Authors' Reply
    Jayashree Sahni

    Dear Editor,

    We thank Mennel et al. and Duker et al. for their interesting comments regarding our article.

    Mennel et al. make some interesting points on the immediate structural changes that occur after photodynamic therapy (PDT), a topic that we felt was outside the scope of our study. We agree that the short-term and long-term changes after treatment are important and need to be taken into account in...

  • Authors' Reply
    Jost B. Jonas

    Dear Editor,

    We would like to thank Drs Sony and Garg for their comments on our study [1]. As also pointed out in the study itself, we completely agree with Drs Sony and Garg that steroids, in this case, intravitreal triamcinolone acetonide, may have to be avoided in the treatment of central serous chorioretinopathy. The purpose of the study was to report on the negative experience we gained. The reason why we p...

  • Ophthalmological follow up of preterm infants at a district general hospital in the United Kingdom
    David C Assheton

    Dear Editor,

    On the recommendation of a number of authors, our department aims to follow up children born prematurely for at least two years [1-3]. Those children who are screened as infants for retinopathy of prematurity (ROP) receive an appointment for review with our orthoptists at six months of age. The orthoptic department until two years of age then follows them up. At this point they receive an appointment...

  • Homonymous hemianopia and neuroplasticity
    Henning Mast

    Dear Editor,

    Many neurologists will disagree with the statement “most [patients with homonymous hemianopia] remain handicapped by permanent field loss”. Indeed it is well known that the majority of stroke patients – the largest group among patients affected by visual field lesions - recover, either completely or partially. Further, neuroplasticity is well established and so far no indications suggest a specific...

  • Classification of ocular surface burns.
    Shabbir Harun

    Dear Editor,

    Although Dua wishes this debate to close, we feel compelled to respond to his most recent e-letter1.

    Dua seems to misunderstand the meaning of the word 'guarded'. We have been careful to use the word 'guarded' rather than poor or other such adjective in terms of prognosis2. Guarded as is currently used when counselling a patient means 'cautious'3. Thus if two patients are told that their...

  • Optical coherence tomography in photodynamic therapy
    Stefan Mennel

    Dear Editor,

    Sahni et al. presented a new terminology to validate its reliability of optical coherence tomography (OCT) and studied the effect of photodynamic therapy (PDT) in patients with subfoveal, predominantly classic choroidal neovascularisation (CNV) secondary to age related macular degeneration (AMD) [1]. The new terminology introduced: neuroretinal foveal thickness (NFT), bilaminar foveal thickness (BFT)...
