  • Response to "Preoperative aqueous humour flare values do not predict proliferative vitreoretinopathy in patients with rhegmatogenous retinal detachment"

    We noticed the article entitled "Preoperative aqueous humour flare values do not predict proliferative vitreoretinopathy in patients with rhegmatogenous retinal detachment" by Mulder and associates with interest.(1)

    Several studies have been published concluding that elevated aqueous flare values seem to be associated with increased risk for PVR redetachment.(2-4) Schroeder et al reported that values >15 photon counts per milliseconds (pc/ms) increases the risk for PVR 16-fold.(4) Hoerster et al showed that the odds ratio for PVR development with preoperative flare values >15pc/ms was 30.7 (p=0.0001) with a sensitivity of 80% and specificity of 79%.(3) Conart et al verified these findings (OR 12.3, p<0.0001 for later PVR in flare values >15 pc/ms).(2)

    In contrast Mulder et al concluded on their data compilation that laser flare measurements are inaccurate in predicting PVR.(1) Logistic regression analyses showed a significant increase in odds with increasing flare at least for the second centre (1) supporting the notion that high flare measurements herald PVR. However, the large variation precluded sufficient sensitivity and specificity to separate between groups. We assume the reason for the large variation is that high-level outliers were included. For center 2 only the highest and the lowest values were excluded, no information is provided for center 1. Values of 100pc/ms, here up to 312pc/ms, are uncommon for the low-level type of i...

  • Re:re: Trends and complications of local anaesthesia in cataract surgery: an 8-year analysis of 12 992 patients
    Thanigasalam Thevi
    Response to: Role of Case Series Studies in the Identification of Anaesthetic Complications Dear Editor, We would like to acknowledge Eke and Kumar for their comments on our article.1 In our retrospective case series study of 12,992 patients, we noted that subtenon anaesthesia had more complications and that both topical and subtenon anaesthesia in our series were the ideal anaesthetics.

  • re: Trends and complications of local anaesthesia in cataract surgery: an 8-year analysis of 12 992 patients
    Tom Eke

    Editor,

    We read Thevi and Godhino's article (1) with interest, but we feel that the methodology does not support their conclusions. They aimed to 'find out the most suitable anaesthesia for patients with fewer complications' in cataract surgery, and reported that 'sub-Tenon anaesthesia [STA] was associated with more intraoperative and postoperative complications ... topical anaesthesia [TA] ... is the ideal a...

  • Comments on: Five-year results of Small Incision Lenticule Extraction (ReLEx SMILE)
    ESHA AGARWAL

    We read with great interest article entitled "Five-year results of Small Incision Lenticule Extraction (ReLEx SMILE)" by Blum et al (1). They concluded SMILE to be an effective, stable and safe procedure for treatment of myopia and myopic astigmatism in the long term. However, few queries come to our mind.

    In their study they observed regression of 0.48 D over a period of five years, which they attributed mainly...

  • Re: Response to AREDS supplements according to genetic factors: survival analysis approach using the eye as the unit of analysis
    Carl C. Awh

    We read with interest the article by Seddon, Silver, and Rosner1, in which the authors studied progression from intermediate AMD to either geographic atrophy or choroidal neovascularization as a function of genetic risk and AREDS treatment assignment. This study of 4124 eyes by leaders in AMD genetic epidemiology is by far the largest series to analyze and validate a gene/treatment interaction. The authors show that CFH an...

    Response to e-letter to the editor

    We thank Dr. Mourits and co-workers for their interest and comments regarding our manuscript on impression-free three-dimensional (3D) printed anophthalmic socket, and appreciate their recognition of its value in the manufacturing of an ocular prosthesis.(1)

    Dr. Mourits and co-workers propose an alternative technique, impression mould through silicon injection in the a...

  • Outcome of two-muscle surgery for large-angle intermittent exotropia in children - A comment
    Shailja Tibrewal

    We read the article titled "Outcome of two-muscle surgery for large- angle intermittent exotropia in children" by the authors Ki Won Jin and Dong Gyu Choi with great enthusiasm.1 The authors have compared the success of two muscle surgery for large angle (>=40 Prism Diopters (PD)) vs moderate-angle (>=20 and <30PD) intermittent exotropia. Neither of the two ranges described, include deviation between 30 to 39PD....
