Introduction
Ultrasonography is a relatively easy, safe and non- invasive examination method which can be used in diagnosis of ocular disorders as complementary to routine ophthalmic examinations.
Objectives
The aim of the study is that the relationship between the ultrasonographic examination of the anterior and posterior segment of the eye and the intraocular pressure.
Methods
Fifty dogs were used as a materials. Only right eyes
of dogs were evaluated without age, race, sex and
eye diseases clasifications. All examinations were performed within a certain order on the eye examination. Schirmer test kit was used to measure the quantitative amount of tear secretion, the eye examination was made by light source, tonovet was used as rebound tonometer for intraocular pressure measurement, direct ophthalmoscopic examination and ultrasonographic examinations were performed.
Results
Ultrasonographic examination showed right anterior segment depth: 0.899 cm; Right front segment width: 1,827 cm; Right eye posterior segment depth: 0.818
cm; Right eye posterior segment width: 1,855 cm. In the analysis of the correlation, intra ocular pressure increased (n: 6) statistical results; Moderate correlation was determined between intraocular pressure and anterior segment depth (medium correlation between 0.4-0.6,
r: 0.551). High correlation was also found between intraocular pressure and anterior segment width (high correlation between 0,6-0,8, r: 0,609).
Conclusions
There was a statistically positive change in the measurements of the anterior and posterior segments in ıntra ocular pressure high. Therefore, in other pathological conditions that may cause glaucoma and intraocular pressure, ultrasound-guided examinations have led to the conclusion that glaucoma can be diagnosed precisely

Introduction
Corneal ulcer can be caused by trauma, foreign body, infection, entropium, trichiasis, districhiasis. The ulcer can be superficial, deep or perforating depending on which layers of the cornea affected.
In veterinary practise the examination of cornea usually made with direct or indirect opthalmoscope and fundus camera. Thanks to development in ophthalmic diagnostics available a new tool, Optical Coherence Tomography (OCT). With the OCT we are able to examine the layers of he cornea almost in histological level.
Objectives
Our goal to show the important role of the OCT in the examination of the cornal ulcers.
Methods
The principle of operation of the Optical Coherence Tomography (OCT) is very similar to the ultrasound with one major difference, that in case of the OCT the physical wave originates from a special light source.
Results
In our study we examined 24 dogs with corneal ulcer. The age of dogs was between 3 weeks and 15 years. During our research we take picture of foreign body in the cornea, perforated cornea, superficial ulcers. The OCT can examine the layers of the cornea, so we were able to determine the type of the ulcer exactly.
Conclusions
With OCT we are able to examine the layers of the cornea so we can make more accurate diagnosis. We can determine the type, depth of the ulcer.
