    1. Relevance of Swept-Source Anterior Segment Optical Coherence Tomography for Corneal Imaging in Patients With Flap-Related Complications After LASIK

      Relevance of Swept-Source Anterior Segment Optical Coherence Tomography for Corneal Imaging in Patients With Flap-Related Complications After LASIK

      Purpose: To evaluate the role of swept-source anterior segment optical coherence tomography (AS-OCT) in the diagnosis and management of laser in situ keratomileusis (LASIK) flap-related complications. Methods: This prospective study included 25 eyes with LASIK flap-related complications imaged using swept-source AS-OCT between February and August 2016 at Alforsan Eye Centre, Assiut, Egypt. The images were acquired using a 6-mm line scan. Results: Imaging of flap-related LASIK complications using AS-OCT revealed specific and nonspecific findings. Of note, epithelial ingrowth appeared as highly reflective lesions below the LASIK flap in the form of islands, nests, or a continuous sheet with or without ...

    2. Macular choroidal thickness in normal Egyptians measured by swept source optical coherence tomography

      Macular choroidal thickness in normal Egyptians measured by swept source optical coherence tomography

      Background To provide a normal database of choroidal thickness (CT) in nine Early Treatment Diabetes Retinopathy Study (ETDRS) subfields in Egypt using deep-range imaging swept source optical coherence tomography (DRI SS OCT). Methods This study included a total of 129 eyes of 71 normal Egyptian subjects, comprising 63 males and 66 females. The mean age was 36.85 ± 14.22 years (range, 16–67 years). The mean axial length was 23.84 ± 0.78 mm. CT was measured in nine subfields as defined by the ETDRS-style grid using a DRI SS OCT, and line measurements of subfoveal choroidal thicknesses (SFCT ...

    3. Spectral domain anterior segment optical coherence tomography in microbial keratitis

      Spectral domain anterior segment optical coherence tomography in microbial keratitis

      Purpose To investigate the spectral domain anterior segment optical coherence tomography (SDAS-OCT) patterns in microbial keratitis (fungal and bacterial keratitis). Design Prospective, cross-sectional, observational study. Methods Twenty eyes of 20 patients with proven fungal and bacterial microbial keratitis, at different stages of the disease, underwent SDAS-OCT imaging. Results Eight eyes presented with proven bacterial keratitis (3 Staphylococcus Aureus, 2 Pseudomonas Aeruginosa and 3 Staphylococcus Epidermidis). Twelve eyes presented with proven fungal keratitis of Aspergillus species. Twelve different SDAS-OCT presentations of fungal and bacterial keratitis were found in this study. Our findings in fungal keratitis grasped two unique patterns of early ...

    4. Spectral domain optical coherence tomography study of pearl-like lesions in the anterior chamber

      Spectral domain optical coherence tomography study of pearl-like lesions in the anterior chamber

      Aim: To study the morphological pattern of pearl-like lesions in the anterior chambers of children before and after management using anterior segment spectral domain optical coherence tomography (SD-OCT). Patients and methods: This was a prospective, observational cross-sectional study of patients presenting with peculiar pearl-like lesions in the anterior chamber of their eyes. 1 mL of betamethasone sodium phosphate (2 mg/mL) and betamethasone dipropionate (5 mg/mL) was injected subconjunctivally. Follow-ups of all patients were conducted for a period of 6 weeks. Anterior segment imaging was done using SD-OCT and also photo slit lamp before and after management. Results: Twelve ...

    5. Spectral domain anterior segment optical coherence tomography assessment of pterygium and pinguecula

      Spectral domain anterior segment optical coherence tomography assessment of pterygium and pinguecula
      Purpose:  To study the morphological patterns of pterygia and pingueculae using high-resolution anterior segment spectral domain optical coherence tomography (SD-OCT). Methods:  Prospective cross-sectional study of 25 eyes presented with pterygia and pingueculae was conducted, and the eyes were examined by anterior segment SD-OCT. Results:  We examined 25 eyes, including 13 eyes with primary pterygia, six eyes with recurrent pterygia, one case with a pseudopterygium and five eyes with pingueculae. Primary pterygia revealed elevation of the corneal epithelium by a wedge-shaped mass of tissue separating the corneal epithelium from the underlying Bowman’s membrane, which became wavy and interrupted. We found ...

    6. Local retinal sensitivity in relation to specific retinopathy lesions in diabetic macular oedema

      Local retinal sensitivity in relation to specific retinopathy lesions in diabetic macular oedema

      Purpose:  To study microperimetric macular sensitivity in diabetic macular oedema (DMO) in relation to lesion characteristics obtained by optical coherence tomography (OCT), colour fundus photography, and fluorescein angiography (FA). Methods:  The study comprised 20 eyes in 15 patients with nonproliferative diabetic retinopathy and recently diagnosed untreated DMO. Investigations included microperimetry, fluorescein angiography, colour fundus photography, and OCT. All measures and gradings were made for each of the nine fields of an early treatment diabetic retinopathy study macula template. Statistical analysis was made using Spearman’s nonparametric test including field and mean values within fields. Comparisons were made within the study ...

    8. Optical coherence tomography and vessel diameter changes after intravitreal bevacizumab in diabetic macular oedema

      Purpose: To assess the effect of intravitreal bevacizumab on diabetic macular oedema (DMO) and retinal vessel calibres. Methods: We performed a consecutive case series study in which 10 consecutive eyes with diffuse DMO, two of which had not previously been treated, received an intravitreal injection of bevacizumab 1 mg, which was followed by two more injections at 6-week intervals. Fundus photography and optical coherence tomography (OCT) were carried out at baseline immediately before injection and at 1, 2.5 and 4 months after the first injection. Outcome measures were best corrected visual acuity (BCVA) in Early Treatment Diabetic Retinopathy Study ...

    9. The predictive value of optical coherence tomography after grid laser photocoagulation for diffuse diabetic macular oedema

      Purpose: To assess the predictive value of optical coherence tomography (OCT) mapping of retinal thickness and intraretinal morphological changes after macular grid for diffuse diabetic macular oedema (DMO). Methods: We carried out a prospective, non-controlled, case series study, in which 28 consecutive eyes with previously untreated diffuse DMO underwent fundus photography and OCT at baseline and at 1, 3 and 6 months after treatment. Results: Macular photocoagulation was followed by a significant reduction in retinal thickness in the foveal centre (− 80 μm) and in the foveal subfield (− 65 μm) from baseline to 6 months (p 0.05). The relative decrease ...

    10. Enhanced optical coherence patterns of diabetic macular oedema and their correlation with the pathophysiology

      Enhanced optical coherence patterns of diabetic macular oedema and their correlation with the pathophysiology
      Purpose: To describe different patterns of diabetic macular oedema (DMO) using a computerized alignment and averaging of sequences in optical coherence tomography (OCT) B-scans and to show the correlation of these patterns with the pathophysiology of the condition. Methods: We carried out a prospective, uncontrolled study, including 46 human subjects with untreated DMO. Enhanced OCT images were produced. We correlated different OCT patterns of DMO with ETDRS visual acuity and with the thickness of the central 1-mm of the macula. We also correlated these patterns with theories of the pathophysiology of DMO. Results: Enhanced OCT images enabled us to examine ...
