چکیده

Purpose. Application of anterior segment optical coherence (AS-OCT) in pediatric ophthalmology. Methods. Retrospective clinical study case series of 26 eyes of 19 pediatric patients throughout a 21-month period, presenting anterior segment pathologies, were submitted to AS-OCT examination (OCT Visante, 1310 nm, Zeiss), noncontact technique, no sedation requirement. Results. AS-OCT images were obtained from 19 patients (range: 2 months to 12 years). Clinical diagnosis of anterior segment abnormalities included cornea disease (n = 7), congenital anterior segment conditions (n = 10), ocular trauma (n = 1), anterior segment surgeries (n = 2), iridocorneal angle abnormalities (n = 4), intermediate uveitis (n = 2). The most common OCT findings were corneal hyperreflectivity and thickening (n = 15), shallow anterior chamber with iris-lens diaphragm anterior displacement (n = 4), atypical corneal curvature (n = 4), corneal thinning (n = 4), peripheral synechiae with angle closure (n = 3), increased anterior chamber depth (n = 2), and proximal portion of glaucoma drainage tube (n = 2). Conclusion. In the present study, noncontact AS-OCT demonstrated to be a feasible technique to evaluate the anterior segment providing anatomic details and useful to clarify diagnosis in the pediatric population.

Clinical Applications of Optical Coherence Tomography in Ophthalmology

Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases.  Furtherm...

Applications of Anterior Segment Optical Coherence Tomography in Cornea and Ocular Surface Diseases

Optical coherence tomography (OCT) is a noncontact technology that produces high-resolution cross-sectional images of ocular tissues. Anterior segment OCT (AS-OCT) enables the precise visualization of anterior segment structure; thus, it can be used in various corneal and ocular surface disorders. In this review, the authors will discuss the application of AS-OCT for diagnosis and management of...

Changing Trends of Imaging in Angle Closure Evaluation

Primary angle closure glaucoma (PACG) is a significant cause of visual disability worldwide. It predominantly affects the Eastern and South Asian population of the world. Early detection of anatomically narrow angles is important, and the subsequent prevention of visual loss from PACG depends on an accurate assessment of the anterior chamber angle (ACA). Gonioscopy has given way to modern day i...

Use of Anterior Segment Optical Coherence Tomography to Determine the Position of the Horizontal and Vertical Extraocular Muscles.

Pediatric ophthalmologists are often faced with a patient who has had previous strabismus surgery without a definitive history or records to confirm what specific surgery was performed. In planning further surgery, the pediatric ophthalmologist is often required to evaluate the previous location of the extraocular muscles. This is usually done while the patient is undergoing the surgery. Once t...
