Birds of two suborders, Accipitres and Falcones were the subjects of the study. The thyroids were always located asymmetrically. In Accipitridae the larger left gland was usually situated significantly more cranially than the right one. In common kestrel, the size of bilateral thyroids was similar while their mutual relationships were ...

Complete blood vessel occlusion is required for the treatment of age-related macular degeneration (AMD). AMD is the leading cause of blindness in developed countries and current treatment regimes have potential to cause collateral damage, or do not remove pre-existing unwanted vasculature. It has been proposed that two-photon excitation (TPE) photodynamic ...

The pterygopalatine fossa (PPF) is a small anatomic region of particular interest in cranial base surgery. Infectious diseases and malignancy may spread through the PPF to contiguous areas as a result of the low resistance offered by the numerous foramina and fissures that surrounds the fossa. We present an anatomic ...

Transient monocular visual loss may be caused by a variety of ophthalmic and systemic conditions. Management depends on identifying the cause. Embolic occlusions of arteries supplying the eye are a most important cause. Such emboli often arise from the heart, aorta, and internal carotid arteries. The most common embolic substances ...

Hummingbirds possess an array of morphological and physiological specializations that allow them hover such that they maintain a stable position in space for extended periods. Among birds, this sustained hovering is unique to hummingbirds, but possible neural specializations underlying this behavior have not been investigated. The optokinetic response (OKR) is ...

Branch retinal vein occlusion (BRVO) is believed to arise at arteriovenous crossing sites. Surgical dissection of the arteriovenous sheath has been proposed as a treatment option, yet induction of a posterior vitreous detachment may be as important in obtaining a successful surgical outcome, suggesting that vitreoretinal traction may play a ...
