For the first time, the intraoperative intralenticular pressure was measured in patients with intumescent cataract. A dependency was defined between the thickness of the lens and the anterior layer of liquefied lenticular masses, anterior chamber depth, and intralenticular pressure magnitude; based on this, a mathematical model for intralenticular pressure measurement was constructed.

We considered the current problem of determining pain sensitivity of different sections of the human body to find the most painless and safe zones for different medical procedures. The study involved 3 groups of students, 8 people in each group. In the first group were Russian boys, in the second – Russian girls, in the third – African girls aged 18–22 years. We carried out studies in 8 areas of the body, which are most often used in medicine for injecting: cheek, shoulder, forearm, wrist, underarm, shin behind (under the knee), iliac and gluteal areas. These areas are most commonly used for various medical procedures. We determined objective differences of sensitivity thresholds of different body sections. As the threshold increases (decrease in sensitivity), these are: underarm, forearm, iliac region, lower leg behind, gluteal region, shoulder. There were no pronounced sexual features of pain sensitivity among boys and girls 18–20 years old. We revealed ethnic features of skin sensitivity. The overall sensitivity of African students is higher than that of Russians. Taking into account the features of tactile and pain sensitivity will reduce the negative sensations of patients during pain-provoking procedures.

Actuality. Complicated cataract surgery in high myopia is accompanied by the high risk of intra- and postoperative complications caused by this background disease. The presence of lens opalescence influences the results of many functional diagnostic tests. Diagnostic and prognostic research of the modern methods of investigation such as spectral optical coherence tomography, ultrasound biomicroscopy and B-scanning is urgent in patients with high myopia and cataract. The true prognosis of visual functions in these patients will allow solving the problem of cataract phacoemulsification expediency, decreasing the risks of complications.Purpose. To determine prognostic criteria of complicated cataract phacoemulsification outcome in high myopia.Patients and methods. 62 patients (101 eyes) with arising or immature cataract and high myopia were examined. All patients underwent ultrasound biomicroscopy of retinal periphery, ultrasound B-scanning of vitreous body and spectral optical coherence tomography of macular zone preoperatively, in the first postoperative days, in a month, in 6–8 months. We performed the correlation analysis of the initial morphological parameters and postoperative visual acuity. To solve the problem of the favorable outcome prognostication (achieving a certain level of visual acuity by the definite term after surgery) the method of binary logistic regression was used.Results and conclusion. The performed mathematical analysis showed the correlation between the postoperative visual acuity and the initial morphological parameters in a myopic eye: the value of ocular anterior posterior axis, the height of the posterior vitreous detachment, posterior staphyloma, the retinoschisis length in the superior outer segment, epiretinal membrane height, pigmented epithelium destruction and discharge, increased choroidal reflectivity, subfoveal choroidal thickness. We built the mathematical models that allowed predicting with high accuracy the probability of achieving a certain level of postoperative visual acuity following cataract phacoemulsification in high myopia.

Nailfold capillaroscopy is currently one of the highly informative methods for assessing the state of microcirculation. The advantages are ease of implementation, non-invasiveness, accessibility of the research object, instant visualization of the microvasculature, painlessness. The object of the study is the nailfold capillaries of the fingers or toes, due to their horizontal position in relation to the surface of the body, which makes it possible to evaluate the capillary throughout. Many authors have shown pronounced microvascular anomalies in type 1 and type 2 diabetes mellitus: tortuosity and dilation of capillaries, a decrease in their density, microhemorrhages, avascular zones, ectasias and aneurysms, newly formed capillaries; a relationship with the duration and compensation of diabetes mellitus as well as the severity of diabetic retinopathy was revealed. Thus, nailfold capillaroscopy can be used as a method for diagnosing and predicting diabetic retinopathy in patients with diabetes mellitus with the aim of early detection of initial changes in the microvasculature and timely retinopathy treatment. Key words: capillaroscopy; nailfold; diabetes mellitus.

Оценивались результаты аккомодографии до и после лазерстимуляции приставкой «Рубин». Значения аккомодационного ответа (АО) и количества выпадений в амблиопичных глазах превышают эти показатели в парных глазах. Значения АО амблиопичного и парного глаза достоверно различаются до лечения, после лечения различия АО не достоверны. Выявлена достоверная значимость различий количества «выпадений» в гистограммах амблиопичного и парного глаз, их количество в амблиопичных глазах достоверно снижается после курса лечения.
