    2. RESCAN 700 allows for real time imaging in eye surgery

      RESCAN 700 allows for real time imaging in eye surgery

      The advent of Optical Coherence Tomography (OCT) in ophthalmology brought a more accurate diagnosis, earlier detection of disease, and more fine-tuned treatment of individual patients’ diseases. Evidence has demonstrated that intraoperative OCT (iOCT) can provide surgeons with crucial imaging of structures below the visible surface. The DISCOVER study was created to evaluate iOCT in eye surgeries. Preliminary results from the study were recently published in the British Journal of Ophthalmology. These results looked at how a specific iOCT system (RESCAN 700) was used in 10 surgeries. The RESCAN 700 features a heads-up display and foot controls for ease of use ...

      TWO-DIMENSIONAL Confocal Imaging Using Oct Light Source And Scan Optics

      Various approaches are disclosed for simultaneously generating optical coherence tomography (OCT) and confocal scanning laser images by spatially separating the signal normally used for OCT imaging with selective reflecting or beam directing devices. In one preferred embodiment, the invention includes a mirror having a central transmission region, such that the radially outer region of the returning signal beam is reflected and used for generating a confocal image while the central part of the signal beam is transmitted and used to generate an OCT image. In other embodiments, the signals may be spatially separated in other ways, such as with an ...

      Artifacts in optical coherence tomography

      Optical coherence tomography (OCT) is now an integral part of management for numerous retinal diseases for diagnosis, treatment planning and follow up. OCT interpretation must involve the understanding of the associated artifacts. These artifacts can mislead physicians to wrong diagnosis or inappropriate management. This review article discusses the various types of artifacts in OCT scans obtained from various devices in various retinal diseases. This article would help to improve the understanding about the various artifacts and their clinical importance.

    9. Volcano like pattern in optical coherence tomography in chronic diabetic macular edema

      Volcano like pattern in optical coherence tomography in chronic diabetic macular edema

      In this article we herein report an interesting vitreo-macular interface abnormality associated with chronic diabetic cystoid macular edema. It is an observational case study of three diabetic patients examined in the diabetic clinic. All the patients had proliferative diabetic retinopathy with chronic macular edema. A serial cross sectional OCT examination and tracking of both the longitudinal progression of macular thickening and vitreo-macular interface revealed cystoid macular edema with a characteristic hyperreflective vitreous shadow emerging from the vitreofoveal interface. All the patients had dehiscence of inner retinal layers. This particular morphological feature at the vitreo-foveolar interface, which we name as “volcano ...

    10. Comparing Gonioscopy With Visante and Cirrus Optical Coherence Tomography for Anterior Chamber Angle Assessment in Glaucoma Patients

      Comparing Gonioscopy With Visante and Cirrus Optical Coherence Tomography for Anterior Chamber Angle Assessment in Glaucoma Patients

      Purpose: The aim of this study was to compare gonioscopy with Visante and Cirrus optical coherence tomography (OCT) for identifying angle structures and the presence of angle closure in patients with glaucoma. A secondary objective was to assess interrater agreement for gonioscopy grading among 3 independent examiners. Methods: Gonioscopy grading using Spaeth Classification and determination of angle-closure risk was performed on 1 randomly selected eye for 50 phakic patients. Images of the same eye using both Visante and Cirrus OCT were obtained in both light and dark conditions. Agreement of angle closure among 3 devices and interrater agreement for gonioscopy ...

      Optical coherence tomographic findings at the fixation point in a case of bilateral congenital macular coloboma

      Background: Congenital macular coloboma is a rare ocular disease that consists of atrophic lesions in the macula with well-circumscribed borders. We report the findings of spectral domain optical coherence tomography (SD-OCT) at the fixation point in a case of bilateral macular coloboma. Case report: The subject is a 4-year-old boy. He visited our hospital at age 1 year and 4 months for the evaluation of strabismus. The fundus examination of both eyes showed round-shaped sharply-demarcated atrophic lesions involving the macula with large choroidal vessels and bared sclera at the base. Immunologic tests including toxoplasmosis, rubella, varicella, herpes virus, and human ...

      Accuracy of 3 imaging modalities for evaluation of the posterior lens capsule in traumatic cataract

      Purpose To compare the accuracy of 3 imaging modalities for preoperative evaluation of the posterior lens capsule in traumatic cataract. Setting Farabi Eye Hospital, Tehran, Iran. Design Case series. Methods The study comprised eyes with traumatic cataract opaque enough to prevent visualization of the posterior lens capsule on slitlamp examination. To detect posterior lens capsule rupture before surgery, imaging was performed with 20 MHz echography (Eye Cubed), anterior segment optical coherence tomography (AS-OCT) (Visante model 1000), and Scheimpflug imaging (Pentacam).
