Swept-Source OCT of a Scleral Tunnel in Choroideremia

Swept-Source OCT Angiography: SS OCT AngioTM

Swept-source OCT angiography of macular telangiectasia type 2.

BACKGROUND AND OBJECTIVE To evaluate the central macular microvascular network in patients with macular telangiectasia type 2 (MacTel2) using optical coherence tomography (OCT)-based microangiography (OMAG). PATIENTS AND METHODS Prospective, observational study of patients with MacTel2 evaluated using a swept-source OCT (SS-OCT) prototype. OMAG was performed using a 3 mm × 3 mm central foveal...

Lens-based wavefront sensorless adaptive optics swept source OCT

Optical coherence tomography (OCT) has revolutionized modern ophthalmology, providing depth resolved images of the retinal layers in a system that is suited to a clinical environment. Although the axial resolution of OCT system, which is a function of the light source bandwidth, is sufficient to resolve retinal features at a micrometer scale, the lateral resolution is dependent on the delivery ...

New Swept-Source OCT for Glaucoma: Improvements and Advantages

When we refer to sweptsource optical coherence tomography (SS-OCT), “swept source” refers to the type of laser incorporated into the device. Instead of the superluminescent diode laser typical of conventional spectral domain OCT (SD-OCT), SS-OCT uses a short-cavity swept laser. Although the swept-source laser has a wavelength centered at approximately 1 μm, the laser actually changes, because i...

Scleral fixation using suture retrieval through a scleral tunnel.

Scleral fixation of intraocular lenses (IOLs) can be performed under the protection of a scleral flap. A variation of this technique uses a scleral tunnel for suture fixation to the eye. Passage of a double-armed suture through the roof of the scleral tunnel with subsequent retrieval of the suture ends through the external incision for tying facilitates scleral fixation. This modification offer...
