Anterior Segment Imaging in Combat Ocular Trauma

Abstract

Purpose. To evaluate the use of ocular imaging to enhance management and diagnosis of war-related anterior segment ocular injuries. Methods. This study was a prospective observational case series from an ongoing IRB-approved combat ocular trauma tracking study. Subjects with anterior segment ocular injury were imaged, when possible, using anterior segment optical coherence tomography (AS-OCT), confocal microscopy (CM), and slit lamp biomicroscopy. Results. Images captured from participants with combat ocular trauma on different systems provided comprehensive and alternate views of anterior segment injury to investigators. Conclusion. In combat-related trauma of the anterior segment, adjunct image acquisition enhances slit lamp examination and enables real time In vivo observation of the cornea facilitating injury characterization, progression, and management.

Utility of anterior segment swept-source optical coherence tomography for imaging eyes with antecedent ocular trauma

“…ASOCT is generally considered analogous to ultrasound imaging except that it uses infrared light rather than sound; therefore, it does not require fluid immersion or probe contact. This not only makes it easier to obtain images but also results in less discomfort for the patients than ultrasound imaging modality [4] .…”

“…The disadvantages of contact methods, such as risk of corneal abrasions, infections due to corneal contact, and discomfort experienced by the patient, have made the noncontact ASOCT imaging devices popular [4] .…”

Photo Documentation In Ocular Trauma

“…Patients were selected on basis of nonprobability consective sampling. Sample size was calculated [8] and total number of patients recruited was 100 to avoid type 2 error. Patients presenting in an eye OPD or admitted via emergency with ocular trauma were included in the study.…”

“…Straightforward photography of the external eye is useful in maintaining a permanent record and in the assessment of small changes in lesion [7].Comprehensive knowledge of patient's history and ocular examination is critical in the management of ocular injuries. Ocular imaging modalities add valuable information for the clinical and surgical care [8].…”

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

“…AS-OCT can be a useful tool in ocular injuries [ 10 ]. Its high resolution is optimal for evaluating depth of injury to the cornea or sclera and the type, size, and location of the foreign body [ 51 , 52 ]. Noncontact scanning capability is also ideal for prevention of further tissue damage in fragile eyes and reducing discomfort of patients.…”
