Orbital cellulitis is a diffuse progressive acute inflammatory process with infiltration and purulent melting of orbital tissue. The disease can occur at any age, but is more common in children aged 4-5 years and young people of working age. Orbital cellulitis in children is preceded by acute respiratory diseases, in adults - chronic and acute inflammation of trauma, airways, oral cavity, sepsis.

The development of acute inflammation of the orbit and its complications is provided by the anatomical and topographical features of the orbit, such as the adjacent cranial cavity and sinuses, the connection of the arteries with the external and internal carotid arterial systems, the absence of valves in the orbital veins. Orbital cellulitis may lead to intracranial complications that endanger not only the eyes but also the patient's life. All these factors set certain requirements for modern diagnostics in order to select an appropriate treatment. The efficiency of treatment depends on adequate assessment of the pathological process, specifying its localization, detecting the presence of necrotic putrefaction. It is impossible to solve this problem without applying modern visual diagnostic methods. Together with traditional investigative methods (analysis of memory data, sequence of presentation of clinical symptoms, laboratory and functional tests), ultrasound, computed tomography and more recently NLS diagnostic methods allow diagnosis at an early stage, thus ensuring the selection of appropriate treatment.

In recent years, many new technologies have been developed and then introduced into practical ophthalmology. The biophilic Biophilia Intruder is becoming the leader in screening diagnostics among various visualization methods, thanks to many aspects (simplicity, usability, informativeness, safety, freedom from ionizing radiation and affordability). Ultramicroscopic scanning revealed that the NLS images of orbital cellulitis showed asymmetry and expansion of the retrobulbar space, and changes in structure and color rendering. However, many important aspects of this problem remain unresolved: the possibility of three-dimensional NLS studies, ultrasonic scanning combined with orbital spectral entropy analysis (SEA) in disease diagnosis has not been investigated; there is a lack of information on the clinical utility of combined NLS imaging in the evaluation of orbital cellulitis. Information on applications in process and treatment efficiency. Therefore, research on this issue must be considered essential.
