Ocular examination is an important aspect of the complete physical examination process; therefore, routine practice of an ophthalmic examination protocol enables the clinician to catalogue his findings and conclude to a diagnosis. Although the eye is a unique and highly complex organ in terms of structure and function, it should never be viewed and examined as an isolated organ, but rather than as a part of the whole, since a great number of systemic diseases reflect on to the eyes. A correct diagnosis in veterinary ophthalmology is often based on anatomical observations and the use of various simple additional ophthalmologic techniques. These may be easily learnt and applied in veterinary practice. The use of these techniques would assist the clinician in establishing a diagnosis and developing a rational treatment. Thorough and systematic ophthalmic examination includes: (i) accurate case history evaluation (signalment and primary complaint), (ii) eye and annexa examination in a lighted room by means of initial observation and close-up inspection, palpation (consisting of exploring the boundaries of the orbit, digital tonometry, eyelid eversion and globe retro pulse) and neuroophthalmologic assessment (including menace response, papillary light reflexes, corneal, oculocephalic, and oculocardiac reflex),) (iii) detailed examination of the external (globe, eyelids and margins, nictitating membrane, conjunctiva, sclera, lacrimal system) and internal (cornea, anterior chamber, iris and pupil, lens, vitreous body, choroid and retina, optic nerve) ocular structures of both eyes, working from anterior to posterior, in a dark room, (iv) tear film production measurement (Schirmer Tear Test), (v) vital dyes use (fluorescein and Rose-Bengal stain), (vi) corneal and conjunctival scrapings (impression smears for exfoliative cytology), collection of specimens for microbiological examination, as well as of aspirates (aqueous humor from the anterior chamber or vitreous paracentesis from the posterior chamber), (vii) tonometry (digital, indentation or applanation), (viii) evaluation of the nasolacrimal drainage apparatus, (ix) ophthalmoscopy (direct or indirect) and (x) vision testing (based on menace reaction, moving objects, obstacle course and visual field evaluation).</span></p>}, number={3}, journal={Journal of the Hellenic Veterinary Medical Society}, author={SCOUNTZOU (E.
