The time delay of the echoes of the waves reflected from the ocular structure is recorded and converted into a geometric distance based on the velocity of sound in the different ocular media.
Exclusion criteria were pseudophakic and/or aphakic patients of any age, patients with concomitant congenital eye disease, and patients with very dense ocular media opacities.
It was impossible to examine the ocular fundus in the pup younger than 2 weeks, because eyelids remained closed and ocular media, especially cornea was not sufficiently clear.
All patients were referred to the department of Radiology from Emergency Room since adequate clinical assessment of the fundus was impossible because of the presence of opaque ocular media.
The technique leads to the sustained expression of therapeutic agents in ocular media over extended periods, alleviating the pain of repeated invasive administrations.
CONCLUSION: We concluded that two dimensional B-scan ultrasound is simple, safe, non-invasive, cost-effective, easily available, reproducible and quick investigative technique which proves accurate and beneficial in opaque ocular media to detect posterior segment pathologies.
The location of foreign body in the posterior segment was carried out by slit lamp and indirect ophthalmoscopy whenever ocular media was clear.
Patients having IOP more than 21 mm of Hg, having any ocular media opacity (Corneal opacity, Mature/hyper mature cataracts, Vitreous hemorrhage), suffering from post-traumatic glaucoma or uniocular glaucoma were not included in the study.
Light rays from OCT can reasonably penetrate mild ocular media opacities like cataract, posterior capsular opacification, vitreous hemorrhage, asteroid hyalosis and vitritis.
Ophthalmic Ultrasound is an essential test done in management of Ocular Trauma, patients with poor view of fundus (posterior segment of eye) due to poor clarity of ocular media.
Eleven months after discharge, the patient's best-corrected visual acuity was 20/25, and his ocular media were clear and without any lesions.
For short pulse lasers, typical in lasers used in fire-control devices (laser rangefinders and designators), the beam is transmitted through the outer ocular media (cornea, aqueous humor, lens, vitreous humor) to a small spot on the retina, resulting in a localized, intense temperature elevation or even a plasma formation that can disrupt membranes and produce a small hemorrahage.
