Intraoperative Use of AS-OCT During Intrastromal Corneal Ring Segment Implantation

Ophthalmic Surgery, Lasers and Imaging Retina, 2012
BACKGROUND AND OBJECTIVE: To evaluate femtosecond laser-created tunnels intraoperatively by anterior segment optical coherence tomography (AS-OCT) during intrastromal corneal ring segment implantation. PATIENTS AND METHODS: The study prospectively examined 13 eyes of 11 patients who

Repeatability of Epithelium Thickness Measured by an AS-OCT in Different Grades of Keratoconus and Compared to AS-OCT/Placido Topography

American Journal of Ophthalmology
To compare agreement of corneal epithelium thickness (ET) between AS-OCT system (RTVue, Optovue) and AS-OCT/Placido topographer (MS-39, CSO) in eyes with different stages of keratoconus (KC), and to assess the repeatability of RTVue AS-OCT.Prospective reliability analysis.KC eyes were classified into forme fruste KC (FFKC), mild, moderate, and severe ...

Spontaneous Deflation of an Iris Pigment Epithelial Cyst Documented with AS-OCT

Ophthalmic Surgery, Lasers and Imaging Retina, 2010
A 3-year-old girl presented with a black pupillary margin iris mass in the right eye diagnosed as an iris pigment epithelial (IPE) cyst, central (pupillary) type. The diagnosis was verified by anterior-segment optical coherence tomography (AS-OCT), which initially showed a circumscribed, round thin-walled cyst with clear lumen attached by a strand to ...

Multilevel CNN for Angle Closure Glaucoma Detection using AS-OCT Images

2020 International Conference on Systems, Signals and Image Processing (IWSSIP), 2020
Glaucoma is identified as one of the main global causes of visual impairment or blindness. There is no cure or possible corrections in case of visual impairment, so the early diagnosis is essential to delay or prevent its progression. However, the disease is asymptomatic in its early stages.

Anterior segment optical coherence tomography (AS-OCT) in strabismus following trauma

Journal of American Association for Pediatric Ophthalmology and Strabismus
We describe 3 cases of ocular trauma that presented with strabismus. Anterior segment optical coherence tomography was used to delineate the morphology of extraocular muscle insertions and proved helpful in diagnosis and management.

Open-Appositional-Synechial Anterior Chamber Angle Classification in AS-OCT Sequences

2020
Anterior chamber angle (ACA) classification is a key step in the diagnosis of angle-closure glaucoma in Anterior Segment Optical Coherence Tomography (AS-OCT). Existing automated analysis methods focus on a binary classification system (i.e., open angle or angle-closure) in a 2D AS-OCT slice.
