Although soft contact lenses protect the ocular media from all sources of UV radiation, it is important for patients to understand that on their own they do not provide sufficient ocular protection since they only inhibit UV reaching the cornea and limbus, leaving other ocular structures like most of the bulbar conjunctiva and adnexa exposed.
Including diagnostic protocols such as ocular ultrasound may improve the ophthalmologic care of endangered raptors injured by blunt trauma, when opacities of the ocular media prevent examination of the internal ocular structures.
Ultrasound B Scan has ability to detect, outline and characterize the nature of soft tissue of eyeball and orbit, regardless the degree of ocular media transparency3.
Both fundus fluorescein angiography and spectral domain optical coherence tomography (Spectralis, Heidelberg Engineering GmbH) studies were performed if the ocular media were sufficiently clear for imaging.
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. Based on radiological diagnosis, the patients were provided treatment (surgical or medical).
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.
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.
