Glaucoma is a chronic progressive neuropathy caused by conditions which lead to damage of the optic nerve and consequently loss of visual function. The most common risk factor is raised intraocular pressure.
Glaucoma is the second leading cause of blindness in the world.

Ocular trauma is one of the most under-recognized causes of vision loss in the developed world. Blunt or penetrating ocular trauma can lead to vision loss through cataract or glaucoma. Etiologies of ocular injury differ in urban areas compared to other settings, and differ from country to country, between different regions of the world, and between differing demographic or socioeconomic classes.

Basic anatomy and physiology of the eye and visual pathways

Author: Alena Furdová

annotation image

Human eye works like a digital camera.

Light is focused primarily by the cornea — the clear front surface of the eye, which acts like a camera lens.
The iris of the eye functions like the diaphragm of a camera, controlling the amount of light reaching the back of the eye by automatically adjusting the size of the pupil (aperture).

Diagnostic and interventional bronchoscopy

Bronchoscopy is one of the most obvious invasive examination in pneumology. Diagnostic bronchoscopy: development of sofisticated technology allowe to perform some diagnostic procedures to make a diagnosis. Therapeutic (interventional) bronchoscopy is a method to perform some treatment modalities in tracheobronchial tree.

Radioactivity II.

Author: Katarína Kozlíková

The lecture „Radioactivity II“ is aimed to explain alpha and beta decays, interaction of these particles with matter, energy spectra and range of particles, protection against radiation.                                                                                                                                                                                                                                   

Ophthalmooncology - Eyelid Tumors

Author: Alena Furdová

annotation image

In spite of being a small organ, the eyelids contain numerous histological elements that can be the origin of benign and malignant lesions.
The eyelids are composed of four layers: Skin and subcutaneous tissue, striated muscle (orbicularis oculi), tarsus, and conjunctiva.                                                                                                                                                          

Ophthalmooncology - Tumors of the Orbit

Author: Alena Furdová

annotation image

Orbital tumors can be benign or malignant and arise primarily within the orbit or secondarily from an adjacent source, such as the eyelid, paranasal sinus, or intracranial compartment. Orbital tumors can also be metastatic from distant sites.
Some types of orbital tumors usually cause proptosis and displacement of the globe in a direction opposite the tumor. Pain, diplopia, and vision loss may also be present. The diagnosis of orbital tumors is suspected based on the history, examination, and neuroimaging (CT, MRI, or both), but confirmation often ultimately requires a biopsy. Causes and treatment vary by age group.

UVEAT TUMORS - I.

Author: Alena Furdová

Most frequent uveal tumors are “ocular melanoma,” “uveal melanoma,” or “choroidal melanoma” are often used interchangeably. The terms describe melanomas, which arise from the eye, and can occur in the iris, ciliary body and/or choroidal regions of the eye. Melanomas are cancers that arise from specific types of pigmented (colored) cells in the body. Melanomas of the eye are rare.
