Xerosis is a corneal and ocular surface disease caused by vitamin A deficiency. It is a rare disease in developed countries, but in third world countries it is a common cause of blindness. We describe a typical xerosis in patient with vitamin A deficiency and long-term malnutrition and alcoholism in our case. In spite of initially serious presentation of the disease, the patient’s response to trea...

Aims: To investigate the dependence of blood vessel density and velocity in ophthalmic artery and arteria centralis retinae of the same eye in patients with normotensive glaucoma. Methods: The sample consisted of 20 patients with normotensive glaucoma (NTG). There were 17 women (mean age 56.1) and 3 men (mean age 60 years). Inclusion criteria for study: visual acuity 1.0 with correction up to ±3 d...

Orbital fractures may be accompanied with severe damage of the eye bulb and other intraorbital tissues. Early clinical findings can be very mild, therefore it is vital to actively seek not only for any damage done to the soft tissues of the orbit, but also for extraorbital complications such as liquorrhea or meningitis. We report a relatively rare case of blow-in fracture of orbital roof in eleven...

Aims: The main aim of this work was to find out if there is a correlation between vessel density (VD) and results of measured perfusion values in ophthalmic artery and in central retinal artery of the same eye in a group with hypertension glaucoma (HTG). Materials and methods: The file included 20 patients with HTG, thereof 13 women of average age 68.7 years (49–80 years) and 7 men of average age ...

Optical coherence tomography (OCT) is a non-contact and non-invasive imaging and diagnostic method, that allows the imaging of ocular tissues on transverse sections in extremely high quality of micrometer resolution. The physical principle of OCT is analogous to ultrasound, but it uses infrared radiation instead of acoustic waves. By using a low coherent radiation source, it is possible to achieve...
