Ophthalmologic Examination T2 Vaughan & Asbury's General Ophthalmology, 18e YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-163420-5 LK accessmedicine.mhmedical.com/content.aspx?aid=55780793 RD 2024/04/24 AB Of all the organs of the body, the eye is most accessible to direct examination. Visual function can be quantified by simple subjective testing. The external anatomy of the eye is visible to inspection with the unaided eye and with fairly simple instruments. With more complicated instruments, the interior of the eye is visible through the clear cornea. The eye is the only part of the body where blood vessels and central nervous system tissue (retina and optic nerve) can be viewed directly. Important systemic effects of infectious, autoimmune, neoplastic, and vascular diseases may be identified from ocular examination.
