To ensure a reliable assessment of the efficacy of myopia control methods and their comparison, it is important that the studies are carried out according to identical protocols. Purpose. To analyze patient examination protocols used by different authors for assessing the efficacy of myopia control methods, and to evaluate the principles of forming the main (treatment) and control groups. Materials and methods. Domestic and foreign authors research works devoted to the assessment of myopia control methods were analyzed, most of which were randomized controlled studies. Results and Discussion. The authors propose their own protocol for evaluation of the efficacy of myopia control methods that includes methods for evaluating the results, recommended number (frequency) and duration of follow-up, represented as a checklist. Conclusion. The proposed protocol can be used for planning and executing a clinical research.

A retrospective analysis of 136 medical histories of patients with eye injuries who applied to the city and regional centers of emergency ophthalmological care and were hospitalized in two specialized ophthalmological departments during one calendar year was carried out. 89% of patients were men, 11% were women; 20% contacted hospitals in winter, 21% – in spring, 30% – in summer and 29% – in autumn. Out of 139 injured eyes, 50% were wounded, 40% were contused, 10% had burns. In cases of eye injuries, 7 (10%) were injuries of the appendages of the eye, 57 (81%) were penetrating injuries, 66% were corneal injuries, 25% – scleral injuries, 9% – corneal-scleral injuries, all of which were severe; 3%  – non-penetrating injuries of the cornea, 6%  – penetrating injuries of the orbit. Among 56 contused eyes, appendages of the eye were damaged in 4 (7%) eyes, all of them were of 2nd degree of severity. Eyeball damage was diagnosed in 35 (63%) eyes: 17 were of 2nd degree of severity, 15 – of 3rd degree of severity, 3 – of 4th degree of severity. Multisystem injuries of the eyeball and appendages of the eye were diagnosed in 17 (30%) eyes. Corneal, conjunctival and eyelid burns of the 2nd degree were diagnosed in 9 eyes, while burns of the 3rd degree were diagnosed in 4 eyes. All cases were chemical burns. 87% cases were civilian injuries, 11.5% were work injuries, while 1.5% were caused by criminal actions. In 2 eyes with non-penetrating corneal injuries, the visual acuity increased after discharge from hospital. Out of 57 eyes with penetrating injuries, the visual acuity increased in 34 eyes and decreased in 8 eyes; in 3 cases of visual acuity decrease, an ophthalmectomy was performed; in 15 eyes the visual acuity remained unchanged. In cases of contusion of the eyeball, out of 52 eyes the visual acuity increased in 39, decreased in 1 eye and remained unchanged in 12 eyes. In cases of burns, out of 13 eyes the visual acuity increased in 10 eyes and remained unchanged in 2 eyes. One patient underwent a blepharorrhaphy.

Parasitic diseases of the eye are a widespread and poorly studied problem. This article is intended to systematize the possible mechanisms of infection and to determine the features of the clinical course and treatment of an ocular dirofilariasis. For this purpose, case reports and research data from medical professionals from Europe and Asia are presented. Conclusions were drawn regarding the dependence of the clinical course on the host  – parasite interaction and immune response and that the only applicable method of treatment in all the cases considered was surgical intervention.

In recent years, the use of contact lenses (CL) in pediatric ophthalmology practice has become increasingly relevant. It is, on the one hand, associated with an increasing compliance with guidelines for using contact lenses and the improvement of lenses’ capabilities, on the other hand. Currently, the indications to contact lens wear in children are the same as for the adults, although with certain specific limitations. In addition, there is also a number of specific indications for using contact lenses in children. In this regard, the purpose of this review was to study the effect of using hyperopic defocus inducing CLs in young children with moderate and high hyperopia.

LASIK (Laser-Assisted in Situ Keratomileusis) is the second generation of laser vision correction methods, which replaced PRK (photorefractive keratectomy) and became a wide-spread method of laser keratorefractive surgery. The technology can improve vision in cases of myopia, hypermetropia, and astigmatism. The article analyzes the advantages and disadvantages of the LASIK method, its risks and side effects. Presented data is obtained from the analysis of scientific publications and by practical means.

Goal. To introduce ophthalmologists and optometrists to the basics of corneal topography. Corneal topography is the main method for assessing corneal surface regularity, the violation of which leads to a deterioration in its refractive properties and a decrease in the quality of vision. The first part of the workshop (The EYE GLAZ. 2020 (22), № 2) presented the main types of topography maps and keratometry data. In the second part, considerations are made regarding mastering the skills of capturing high-quality images and choice of color maps for analysis. Topography patterns as well as topographic signs of keratoconus are also discussed. Conclusion. Placido-based corneal topographers are a useful tool for evaluating the anterior corneal surface, fitting contact lenses and diagnosing keratoconus. Slit-scanning topographers, additionally, are capable of corneal pachymetry and analyzing the posterior surface of the cornea, which allows for carrying out a more detailed assessment and diagnosing keratoconus at preclinical stage.

The combination of an optical biometer, corneal topographer and pupillometer in one device is extremely useful in the practice of a cataract surgeon, especially when it comes to the implantation of toric and multifocal intraocular lenses. The additional Myopia Progression Module can be used in the practice of a pediatric ophthalmologist.
