    1. Pupillary dilation improves quality, reproducibility of OCT in glaucoma patients

      Performing optical coherence tomography after pupillary dilation appears to produce more reproducible, higher quality images for evaluating glaucoma patients compared with scans obtained on undilated eyes, according to a study by researchers in the United Kingdom. "Acquisition of high quality OCT images was not possible without pupillary dilatation in about 25% of the patients," the authors said.

    2. Massachusetts Eye and Ear Infirmary Uses Newest Laser Treatment for People With Diabetic Eye Disease

      The Massachusetts Eye and Ear Infirmary recently acquired the newest laser for treating people with diabetic retinopathy. The Pattern Scan Laser Photocoagulator (Pascal) by OptiMedica is FDA-approved primarily for treatment of diabetic retinopathy and diabetic macular edema. Diabetic retinopathy is the most common diabetic eye disease and is a leading cause of blindness in American adults, according to the National Eye Institute of the National Institutes of Health (http://www.nih.nei.gov). The disease is caused by damage to blood vessels in the retina near the back part of the eye. The Pascal laser allows for faster, more precise ...

    4. Correlation between visual function and photoreceptor inner/outer segment junction in patients with retinitis pigmentosa.

      PurposeTo determine whether a significant correlation exists between the visual acuity or foveal thickness and the status of the inner and outer segment junction (IS/OS) of the photoreceptor in patients with retinitis pigmentosa (RP).MethodsThree hundred eyes of 163 patients with RP were examined with the optical coherence tomography (OCT). The IS/OS appeared as a distinct, highly reflective line just vitread of the retinal pigment epithelium in the OCT3 images. The IS/OS line was graded into three groups. The correlations between the grade of the IS/OS and age, best-corrected visual acuity (BCVA), and central foveal thickness ...

    7. The use of optical coherence tomography in hereditary optic neuropathies: description of a family.

      (Article in Spanish) CASE REPORT: This report describes two siblings, a woman aged 44 years and her brother aged 29 years, who both complained of visual loss in both eyes. The woman had bilateral optic nerve (ON) temporal pallor and severe reduction of ON fibre layer thickness in this area. Both she and her brother had cecocentral defects in perimetry and color vision deficiency with a marked tritanopia deficit. DISCUSSION: ON pallor, limited to the temporal region, is the basic criterion for the diagnosis of dominant optic atrophy. Optical coherence tomography can be a useful technique in defining the diagnosis ...

    9. Activity of neovascular lesions treated with bevacizumab: comparison between optical coherence tomography and fluorescein angiography

      Abstract Purpose  To investigate whether examination with the non-invasive optical coherence tomography (OCT) alone is sufficient to ascertain the need of re-treatment with bevacizumab for exudative age-related macular degeneration (AMD) or the invasive fluorescein angiography (FA) is needed. Method  Two independent examiners reviewed FA and OCT images and performed a semi-quantitative assessment from 0=no activity to activity 1–3, mild, moderate and advanced, respectively. Weighted Kappa indices were performed to calculate the concordance between OCT and FA. Results  A total of 153 OCT and FA examinations of 69 patients were evaluated, mean 2.2 examinations per patient. The mean ...

    13. Comparison of Optic Disc Margin Identified by Color Disc Photography and High-Speed Ultrahigh-Resolution Optical Coherence Tomography

      Objective  To determine the correspondence between optic disc margins evaluated using disc photography (DP) and optical coherence tomography (OCT). Methods  From May 1, 2005, through November 10, 2005, 17 healthy volunteers (17 eyes) had raster scans (180 frames, 501 samplings per frame) centered on the optic disc taken with stereo-optic DP and high-speed ultrahigh-resolution OCT (hsUHR-OCT). Two image outputs were derived from the hsUHR-OCT data set: an en face hsUHR-OCT fundus image and a set of 180 frames of cross-sectional images. Three ophthalmologists independently and in a masked, randomized fashion marked the disc margin on the DP, hsUHR-OCT fundus, and ...

      Incision construction, architecture fight infection
      Among many factors surgeons cite to prevent clear corneal cataract surgery infection, wound construction and architecture are ‘primary’ ataract surgeons should focus on wound construction and architecture when working to avoid infections among their patients. A special focus on that area of surgery is credited by two senior surgeons as the main reason they have avoided infections for many years. More surgeons have focused on infection avoidance as some data have indicated an increasing rate of e

    20. Treatment of retinal detachment

      An apparatus and minimally invasive method for removing fluid from a subretinal space to allow a detached retina to flatten. An apparatus, comprising a fluid withdrawal device and a guide for advancing and placing the device, is positioned on the exterior eye surface at the detachment site. Various embodiments of the apparatus are disclosed. Using the guide, the surgeon advances the device into the fluid-filled space and drains fluid, allowing the retina to flatten. Additional injection of saline or gas into the vitreous cavity normalizes intraocular pressure, and the patient is ambulatory immediately afterward. Unlike other retinal attachment techniques, in ...
