Optical Coherence Tomography
4
Feb

Overview

Optical coherence tomography provides micrometer scale cross sectional images. It is widely used in ophthalmology and increasingly in other specialties. OCT reveals microstructure and supports quantitative analysis.

Ophthalmic Applications

Retinal OCT assesses macular edema and degeneration. Anterior segment OCT evaluates corneal and angle anatomy. OCT angiography visualizes retinal and choroidal vasculature without dye.

Non Ophthalmic Uses

OCT is explored for dermatology cardiology and gastroenterology applications. It can image mucosal and vascular microstructure in research settings. Translation to clinical practice requires validation and workflow integration.

Future Directions

Higher speed and resolution systems expand OCT capabilities. Multimodal imaging combines OCT with fluorescence and other contrasts. Quantitative biomarkers support diagnosis and monitoring.

Imaging for Ophthalmic Surgery Planning

Overview

Imaging provides detailed assessment of retinal corneal and orbital anatomy for surgical planning. Modalities include OCT ultrasound and MRI depending on the target. Accurate imaging improves surgical outcomes and patient counseling.

Retinal Surgery

OCT maps macular structure and guides planning for vitrectomy and membrane peeling. Quantitative OCT metrics monitor disease progression and surgical response. Integration with clinical exam optimizes timing of intervention.

Corneal and Refractive Planning

Anterior segment OCT and topography guide corneal surgery and refractive procedures. Imaging assesses thickness curvature and irregularity for personalized planning. Postoperative imaging monitors healing and complications.

Orbital Surgery

CT and MRI delineate orbital masses fractures and optic nerve relationships for surgical planning. High resolution imaging informs approach and risk assessment. Multidisciplinary collaboration with oculoplastics enhances care.

Ocular System

Overview

The ocular system captures light and converts it into neural signals for vision. Key structures include the cornea lens retina optic nerve and extraocular muscles. Ocular blood supply and intraocular pressure maintain function and ocular health.

Anterior Segment

The cornea anterior chamber iris and lens focus light onto the retina and regulate intraocular pressure. Aqueous humor dynamics influence glaucoma risk. Slit lamp and ultrasound imaging evaluate anterior segment pathology.

Retina and Optic Nerve

The retina contains photoreceptors and neural layers that transduce light into electrical signals. The optic nerve transmits visual information to the brain and is vulnerable to ischemic and compressive injury. Fundus imaging OCT and MRI assess retinal and optic nerve disease.

Clinical Relevance

Ocular conditions include cataract glaucoma retinal detachment and optic neuropathy. Timely diagnosis and intervention preserve vision and prevent irreversible loss. Multimodal imaging guides surgical and medical management.

Ophthalmology

Overview

Ophthalmology provides vision assessment medical and surgical treatment for ocular disease with specialized imaging such as OCT and fundus photography.

Outpatient Clinics and Procedures

Cataract surgery glaucoma management and retinal interventions are delivered in clinic and OR settings with perioperative care.

Diagnostic Imaging

Optical coherence tomography fundus photography and ultrasound support diagnosis and monitoring of retinal and optic nerve disease.

Low Vision and Rehabilitation

Services include visual aids rehabilitation and coordination with community resources to maximize functional vision.

Optical Coherence Tomography OCT

Feb

Overview

OCT provides micron scale cross sectional images of tissue microstructure widely used in ophthalmology and intravascular imaging.

Technique

Interferometric detection of backscattered light yields high resolution images. Catheter or probe based delivery adapts OCT to different organs.

Clinical Uses

Retinal layer assessment in ophthalmology and coronary plaque microstructure in cardiology.

Limitations and Safety

Limited penetration depth and need for clear optical window. Specialized probes required.
