  • Re: Global variations and time trends in the prevalence of primary open-angle glaucoma: a systemic review and meta-analysis
    Ching-Yu Cheng

    Dear Editor,

    We read with interest the article by Kapetanakis et al.[1] The authors presented a systemic review of published population-based surveys to provide estimates of global and regional prevalence of primary open- angle glaucoma (POAG). The authors claimed that this review provided the most precise estimates of POAG prevalence thus far, as they adopted a more "inclusive" approach, compared to previous re...

  • Real life visual improvements with anti vascular endothelial growth factor treatment for wet age-related macular degeneration - Absolute or relative?
    Balasubramanian Ramasamy

    Dear Editor

    We congratulate Holz et al.1 on their most important contribution to anti-vascular endothelial growth factor therapy in neovascular age-related macular degeneration (n-AMD). We think it is important to note that their main finding "visual acuity improved until about day 120; thereafter visual acuity changes were not maintained" does not contradict the findings of the MARINA2 [Ranibizumab Vs sham in...

  • Amniotic membrane graft to conjunctival flap in treatment of non-viral resistant infectious keratitis: a randomised clinical study
    Abdullah ILHAN

    Dear Editor; We have read the article entitled "Amniotic membrane graft to conjunctival flap in treatment of non-viral resistant infectious keratitis: a randomised clinical study" by Abdulhalim et al. with interest.1 The authors compare the results of bipedicle conjunctival flap and cryopreserved amniotic membrane graft in the treatment of non-viral infectious keratitis resistant to medical treatment. We want to express...

  • Response to " Recovery of photoreceptor inner and outer segment layer thickness after reattachment of rhegmatogenous retinal detachment"
    Roshan T

    We read with great interest the study" Recovery of photoreceptor inner and outer segment layer thickness after reattachment of rhegmatogenous retinal detachment" by Terauchi G, et al.[1] Authors concluded that thickness of inner segment layer (20.4 +/- 5.0 microns) at one month after surgery was significantly less than fellow eye (28.9 =/- 2.9 microns). However, we know that the axial resolution of Spectral Domain(SD)...

  • Genetic Testing for Chromosomal Aberration in Choroidal Melanoma
    Kakarla V. Chalam

    The authors have investigated the and compared the chromosome 3 aberrations of Choroidal melanoma (CM) as determined by multiplex ligation probe amplification (MLPA) or microsatellite analysis (MSA)in intra ocular tumor biopsies with those results obtained from subsequent endoresection/enucleation of the same Choroidal melanoma. However few points need clarification from the authors: 1. Since the investigators used few ma...

  • response to: 3D printed reproductions of orbital dissections: a novel mode of visualising anatomy for trainees in ophthalmology or optometry
    Victoria A Nowak

    Dear Editor,

    We read the article '3D printed reproductions of orbital dissections: a novel mode of visualising anatomy for trainees in ophthalmology or optometry' by Adams JW. et al with great interest. The authors have successfully identified the need for experience handling and navigating through anatomical material to understand clinical ophthalmology. Furthermore, they have brilliantly created a means for th...

  • Re:Significance of hyper auto fluorescent (HAF) ring in choroidal neovascularization (CNV) in Age related Macular Degeneration (AMD)
    William R. Freeman

    Dear Editor,

    Dr. Sagar and colleagues made reference to our paper "Significance of the Hyperautofluorescent Ring Associated with Choroidal Neovascularization in Eyes Undergoing Anti-VEGF therapy for Wet Age-Related Macular Degeneration", and pointed out the fact that they did not find a statistically significant difference in subretinal fluid (SRF) between eyes with and without a hyperautofluorescent ring (HAF) i...

  • GRADES and DSA with respect to cancer risk following irradiation in childhood
    Sunil Moreker

    We thank the authors for their prompt reply and do want to thank them for this wonderful paper which definitely serves as an excellent continuing professional development(CPD) module for us and will also be used by many CPD providers immediately after its publication

    But another CPD module one engages in, is the GRADE system. And that has set me thinking trying to fill my learning gaps and the following is ju...

  • Re:Orbital lymphatic malformation may shrink with treatment of anaemia
    Alex Barnacle

    The authors thank Mr Moreker for his letter regarding our series. We agree that these are often complex cases and that each patient should be assessed holistically and discussed individually, ideally in a multidisciplinary setting. We do not check haemoglobin levels in all the patients referred to us, in part because severe anaemia in otherwise well children is rare in the UK population, but we agree that this should be...

  • Re:Re:Trephination size and success of big-bubble formation in deep anterior lamellar keratoplasty for keratoconus.
    Alireza Peyman

    The response by Feizi et al is comprehensive and notable. But the condition could be simply explicated by a clear demonstration of actual data in a table representing DALK success-failure versus different trephination diameters. If the authors accept to publish these data, every reader would be able to deduce the practically applicable end result.
