  • The role of enhanced depth imaging optical coherence tomography in chronic Vogt-Koyanagi-Harada disease
    Salih Uzun

    Dear Editor, We have read and reviewed the article entitled "The role of enhanced depth imaging optical coherence tomography in chronic Vogt-Koyanagi-Harada disease''which was written by Jap and Chee with great interest [1]. The authors evaluated 52 patients with chronic Vogt-Koyanagi-Harada (VKH) disease using indocyanine green angiograms (ICGAs) and optical coherence tomography (OCT). They discovered that the subfoveal...

  • Re:Comment on: Changes observed in diabetic retinopathy: eight-year follow-up of a Spanish population
    Pedro Romero-Aroca

    Response to E-letter. Thank very much for reading our article. It is true that oral insulin analogues can lead to increased growth hormone, increasing its effect over diabetic retinopathy, but previously it should exist a blood-retina barrier (BRB), despite in patients with preexisting diabetic retinopathy the BRB rupture exist in some amount. It is possible that oral insulin analogues can affect the diabetic retinopathy...

  • Predictive value of QFT-G alone in cases of presumed ocular tuberculosis
    Rohan Chawla

    Dear Editor,

    We read with interest the article titled "Predictive factors for treatment failure in patients with presumed ocular tuberculosis in an area of low endemic prevalence" by Agarwal et al published in Br J Ophthalmol 2016;100:348-355.

    We wanted to point out few things regarding the article - The diagnosis of ocular tuberculosis was presumptive in most cases. The authors have used clinical guide...

  • Comment on: Changes observed in diabetic retinopathy: eight-year follow-up of a Spanish population
    Abdullah KAYA

    I read with great interest the article by Romero- Aroca et al. titled "Changes observed in diabetic retinopathy: eight-year follow-up of a Spanish population" [1]. Insulin usage has found to be a risk factor for progression of DRP. Authors conclude this result as relaxation of patients in metabolic control. Beside this conclusion, insulin analogues may directly cause progression of DRP. Insulin and its analogues stimulate ins...

  • Comment on: Short-term choroidal thickness changes in patients treated with either ranibizumab or aflibercept: a comparative study
    Salih Uzun

    Dear Editor,

    We have read and reviewed the article entitled as "Short-term choroidal thickness changes in patients treated with either ranibizumab or aflibercept: a comparative study'' by Kim et al. with interest.1 The authors analyzed 240 eyes of 240 treatment-naive neovascular AMD patients who treated with three-monthly injections of either ranibizumab (ranibizumab group) or aflibercept (aflibercept group). Th...

  • Comparison of trabeculectomy versus Ex-PRESS: 3-year follow-up.Gonzalez-Rodriguez et al.doi:10.1136/bjophthalmol-2015-307161.
    Amit S Nene

    We read with great interest the study titled as "Comparison of trabeculectomy versus Ex-PRESS: 3-year follow-up" by Gonzalez-Rodriguez et al [1].We congratulate their efforts for conducting the study with a follow up of 3 years, making the results more significant.They concluded that success rates, mean IOP, number of anti-glaucoma medications and final visual acuities were similar between the two groups after 3 years. T...

  • Characteristics and quantification of vascular changes in macular telangiectasia type 2 on optical coherence tomography angiography
    Chun Ding

    EDITOR:

    With great interest,We have read the article by Chidambara1 and partners on characteristics and quantification of vascular changes in macular telangiectasia type 2( MacTel 2) on optical coherence tomography angiography(OCTA).The authors concluded that OCTA helps understand the pathology and disease progression better in MacTel 2.We commend their interesting and important work on this subject.However, w...

  • Cigarette smoke extract-mediated oxidative stress and fibrotic-related genes expression may contribute to poor response to steroids therapy in Graves' ophthalmopathy
    Yu-Fan Chang

    We read with great interest the article entitled "Smoking was associated with poor response to intravenous steroids therapy in Graves' ophthalmopathy" by Xing et al [1]. Cigarette smoking is known to be the most important risk factor for the development or deterioration of GO, and it is associated with poor response to treatment for GO. However, the exact mechanisms which prove deleterious effect of cigarette smoking on GO rem...

  • Increased expression of connective tissue growth factor play a role in the pathogenesis of thyroid eye disease
    Yun-Chun Peng

    We read with great interest the article entitled "Pathogenesis of thyroid eye disease: review and update on molecular mechanisms" by Khong et al [1]. We would like to contribute to the article with our novel findings.

    In our previous study, we first demonstrated the up-regulation of mRNA and protein expression of fibrosis-related genes including fibronectin, apolipoprotein J and connective tissue growth factor...

  • Optic disc edema in astronauts following long-duration space flight
    Thomas H. Mader

    Optic disc edema in astronauts following long-duration space flight

    We commend Morgan and colleagues for their discussion of optic disc changes during and after long-duration space flight (LDSF). 1 They note that astronauts after LDSF have developed clinical features (disc edema, globe flattening) similar to those of idiopathic intracranial hypertension (IIH) that may persist for many months post flight and sugg...
