The aim of this study was to compare the effect of intravitreal diclofenac, a non-steroidal anti-inflammatory drug (NSAID), with that of bevacizumab, a well-known anti-vascular endothelial growth factor (VEGF) drug, in the treatment of diabetic macular edema (DME). Diclofenac was chosen in this study because it has both features of NSAIDs and corticosteroids by inhibiting the cyclooxygenase (CO...
BACKGROUND Most patients with multiple sclerosis without previous optic neuritis have thinner retinal layers than healthy controls. We assessed the role of peripapillary retinal nerve fibre layer (pRNFL) thickness and macular volume in eyes with no history of optic neuritis as a biomarker of disability worsening in a cohort of patients with multiple sclerosis who had at least one eye without op...
PURPOSE The purpose was to study preinjection optical coherence tomography-related factors in age-related macular degeneration eyes with retinal pigment epithelial detachment (PED) that may predispose retinal pigment epithelial (RPE) tears associated with intravitreal bevacizumab injections. METHODS This multicenter retrospective case series involving 9 retina specialists and 7 centers invest...
Background & Aim: Macular photocoagulation is the standard treatment for clinically significant macular edema (CSME), but some of patients do not respond to it. The aim of this study was to compare the results of intravitreal injection of triamcinolone acetonide (IVTA) and bevacizumab (IVB) in patients with CSME. Patients and Method: In this prospective randomized double-blind clinical tria...
Improvement of reproducibility of macular volume measurements using the Heidelberg retinal tomograph
We thank Jay Chhablani and William Freeman for their interest and comments regarding our study. The study validated axonal integrity as a measure of visual potential. In macular edema, abnormal fluid accumulation between the two plexiform layers produces mechanical stress on the bipolar axons. Considering that bipolar axons represent the sole communication between photoreceptors and ganglion ce...
Background: optical coherence tomography is one of the most valuable imaging techniques in the evaluation of macula. Objective: to investigate the repeatability and reproducibility of OCT in measuring the macular thickness in normal eyes before and after pupil dilation. Methods: A total of 44 eyes were enrolled. All subjects underwent macular thickness measurement using the Cirrus SD-OCT ma...
Abstract PURPOSE To evaluate the macular, retinal nerve fiber layer (RNFL) and choroidal thickness alterations by using spectral-domain optical coherence tomography (SD-OCT) in postmenopausal, pregnant non-pregnant women. PATIENTS AND METHODS A comparative study included a total of 42 eyes (Right eye) healthy females period from march 2019 to September divided into 3 groups: a) Non b) Pregnant ...
purpose: to report a case of severe macular edema following the taking of fingolimod in multiple sclerosis. case report: a 34-year-old woman with a long history of relapsing-remitting multiple sclerosis presented complaining of blurred vision in the left eye that started 1 week before the presentation. she had been taking fingolimod for 4 months. she was not diabetic and had no history of uveit...
AIM To provide the normative data of macular and retinal nerve fiber layer (RNFL) thickness in Indians using spectral domain OCT (Spectralis OCT, Heidelberg Engineering, Germany) and to evaluate the effects of age, gender, and refraction on these parameters. DESIGN Observational, cross-sectional study. MATERIALS AND METHODS The eyes of 105 healthy patients aged between 20-75 years, with no ...
