Some aspects of the comparative characteristics of different computerized perimetry methods

Static perimetry, made using Humphrey and Octopus expert class perimeters, is called the standard automated perimetry (SAP); and for more than 30 years, it is the “gold standard” in assessing the visual field in glaucoma diagnosis. Currently, many computer perimeters appeared on the Russian market. The article reviews modern methods of computerized perimetry which are most widespread in our country and presents their comparative characteristics. (For citation: Serdyukova SA, Simakova IL.

In recent years, telemedicine (TM) has been gradually introduced into ophthalmology in the form of teleophthalmology (TO), because most of the eye diseases can be photographed and transmitted via Internet. The most wide development of TO has involved the field of diabetic retinopathy (DR) diagnosis, primarily due to the high prevalence of diabetes mellitus in the world. Examples of the well-established operation of remote DR screening centers exist in different countries of the world. There are many studies published, which compare a remote examination with a personal one, and according to their data, TO screening is no worse, than traditional screening. In addition to DR, TO also covers the diagnosis of glaucoma, age-related macular degeneration, and other ophthalmic conditions. In this article, we present an overview of modern TO centers in different countries, the features of their organization and global results that have been achieved during their existence. New technologies developed to facilitate the work of such centers will also be touched: image analysis algorithms, portable diagnostic equipment, medical information systems. The prospects for introducing TO into Russian medical practice are considered separately.

PURPOSE. To study the needs of practical ophthalmologists concerning the functionality and performance of automatic perimeters, and offer a possible solution to meet these needs.METHODS. An online survey of Russian ophthalmologists was organized and conducted. The survey was attended by specialists representing various medical institutions and medical research centers. As a result of the survey, 132 filled questionnaire forms were received and analyzed using the Kano and 4C models.RESULTS. According to experts, it is necessary for ophthalmologists to have an accessible automatic perimeter equipped with the screening (for the initial examination of patients) and threshold (to clarify the depth of photosensitivity disturbance of detected visual field defects) strategies. The general requirements for the functional characteristics of the screening and threshold tests of the automatic perimeter have been determined: small variability of repeated results, the speed and simplicity of the study — particularly, by employing the Frequency Doubling Technology (FDT), a non-standard perimetry technique. The requirements of users for the operational method of the automatic perimeter have been determined: absence of the need for a specially prepared room and place, mobility, portability, maximum ease of use to ensure the possibility of performing screening and primary diagnostics outside medical institutions, including by mobile medical teams, and also to allows examinations of individuals with disabilities, including bedridden patients, both in the hospital and at home.CONCLUSION. Based on the study data, the needs of ophthalmologists in the functional and operational characteristics of modern automatic perimeters were identified showing that the automatic perimeters presently used by modern medical institutions are far from optimal in terms of their properties/characteristics. These devices do not allow perimetry to be performed on patients with disabilities, including bedridden patients, neither at home nor in the hospitals. In addition, these devices require a darkened room, they are difficult to use, while their licensing documentation states that only ophthalmologists can conduct the examinations. Manufacturers do not offer solutions tailored to the individual needs of specific user groups — outpatient ophthalmologists who in particular work with disabled patients.
