Glaucoma is classified into the category of eye diseases associated with visual nerve damage responsible for transmitting visual information from the eye to the brain and is the leading cause of visual impairment and blindness in the world. It is chronic and progressive, and it often advances imperceptible. Because of the absence of symptoms indicating the existence of this disease, it is often referred to as a "silent vision thief". If patient experiences eye fatigue, trouble focusing, dizziness, headache, eye discomfort, pain, nausea and vomiting, be sure to suspect the presence of glaucoma and seek medical help. The underlying signs of this insidious disease are high eye pressure, ocular nerve damage and defects in visual field. Due to untimely observation of the damage it can cause blindness. In the diagnosis of glaucoma, in addition to the physical examination of the eye, perimetry, tonometry, gonioscopy, optical coherence tomography (OCT) and pachymetry, attention should be paid to anamnesis because professionally and conscientiously taken anamnesis is the basis for the establishment of a correct diagnosis and plays a very important role in the proper choice of therapy. The role of a nurse / medical technician is of crucial importance at all levels of health care. Starting from preventative action in a healthy population, participating in diagnosis, treatment, preoperative preparation, intraoperative and postoperative care, up to patient and family education on the new onset situation and improving the quality of life. The goal of the thesis is to define glaucoma, and the risk factors for its formation. The classification of glaucoma, diagnostic procedures, methods of treatment and role of nurse/medical technician in their implementation is presented. An emphasis has been placed on the implementation of nursing care in glaucoma patients and the most common nursing diagnoses that occur in patient care are elaborated.
