Computerized visual field testing (computerized perimetry) is a diagnostic method used to diagnose glaucoma early, assess visual impairments caused by glaucoma, and monitor the effectiveness of antiglaucoma therapy. It is based on the early detection of changes in visual field the patient is often unaware of, which occur as a result of increased eye pressure in patients with glaucoma. Oculus Twinfield is a device for computer determination of the visual field (computer perimeter) by German company Oculus, one of the world's leading manufacturers of ophthalmic diagnostic equipment. The examination is carried out by the patient sitting at the apparatus on the surface of which light stimuli are emitted in the form of points the patient should notice. By pressing a button, the patient confirms they have seen the light stimulus, which is registered by the computer. By processing the received information, that is, observed and unobserved light stimuli (points), the computer outputs a graphic and numerical representation of the patient's visual field. These results make it possible to make a diagnosis or monitor disease progression. "Professional - Dr Suvajac" eye hospital has two Oculus Twinfield devices, which only a few regional clinics can boast of.
Avanti XR device by US company Optovue is the most advanced and accurate OCT diagnostic device for analyzing corneal epithelium. It has 5 micron resoltuion, which means that it can detect pathological changes in eye tissues that do not have to be larger than 200th of a millimeter. Diagnostic imaging is non-contact, therefore completely painless and lasts only a few minutes. Diagnostic imaging of the optic nerve and the nerve fibers layer on the fundus allows for the earliest detection of glaucoma, which is crucial in its treatment.
Laser optic nerve imaging or Heildeberg retinal tomography (HRT) is a highly accurate diagnostic procedure for the early detection of glaucoma. HRT imaging gives us a detailed insight into the structure of the optic nerve as well as the thickness of the nerve fiber layer of the retina, that is, it gives us an insight into the structures that are damaged from glaucoma as a result of increased eye pressure. It is an indispensable part of the diagnosis in the case of suspected glaucoma as it is an objective diagnostic method. Being an objective method refers to the fact that HRT imaging gives us insight into the degree of morphological and structural damage, while subjective methods, such as the computerized visual field testing, give us insight into the degree of functional damage. Together, these two diagnostic procedures give us a complete insight into possible damage caused by glaucoma. Indications for HRT imaging include any suspicion of glaucoma, whether as a result of elevated eye pressure or a slightly altered optic nerve structure observed at eye examination. Also, periodic HRT imaging is indicated in the case of an already diagnosed glaucoma to monitor disease progress, i.e. the effect of the therapy and its possible correction to ensure the best treatment outcome.
Professional Eye Hospital is one of the few institutions with a Ziemer PASCAL tonometer. It is the most modern eye pressure measuring device. It works on the principle of dynamic contour tonometry. What sets it apart from classic tonometers used to measure eye pressure are much more accurate eye pressure values in corneas with altered biomechanical characteristics, which is the case in patients with thin or thick corneas, patients with keratoconus, or patients who have had laser vision correction.
