[Optimization of phacoemulsification technique for Morgagnian cataract].

Purpose: This study was conducted to develop a new optimized phacoemulsification technique for Morgagnian cataract taking into account the anatomical and topographic parameters of the lens nucleus.

Material And Methods: A working classification of Morgagnian cataract was developed based on the size of the nucleus: if the edge of the nucleus is visualized at the upper edge of the pupil or between the upper edge and the middle of the pupil, it was classified as an initial stage of Morgagnian cataract with a large nucleus; if the upper edge of the nucleus is visualized in the middle of the pupil and below, it was classified as an advanced stage of Morgagnian cataract with a small nucleus. The first group included six patients who underwent surgery using the scaffold technique with removal of the whole small nucleus into the anterior chamber.

[Evaluation of the diagnostic capabilities of nailfold capillaroscopy in diabetic retinopathy].

Purpose: This study evaluates the diagnostic capabilities and the prognostic value of nailfold capillaroscopy data of patients with diabetic retinopathy (DR) to develop an algorithm of monitoring patients with type 2 diabetes mellitus.

Material And Methods: The study involved 90 patients (mean age 67 years), among them 31 with nonproliferative diabetic retinopathy, 29 patients with proliferative DR and 30 patients without retinopathy. In addition to conventional ophthalmological examination, optical coherence tomography angiography (OCTA) on the Optovue RTVue-100 device (USA) was performed using en face vessel density protocol to examine the state of the microvasculature of the superficial and deep layers of the vascular plexus of the central retinal zone, as well as nailfold capillaroscopy using computerized capillaroscope KK-01 (ZAO Centr Analiz veshhestv, Russia).

[Prognostic value of matrix metalloproteinases in the development of diabetic retinopathy in the elderly].

The development of diabetic retinopathy is associated with matrix metalloproteinases, but they are rarely used to predict this pathology. The aim of the study was to predict the development of non-proliferative diabetic retinopathy in old age by the level of matrix metalloproteinases in blood plasma. The main study group consisted of 63 patients aged 60-74 years with type 2 diabetes mellitus and non-proliferative diabetic retinopathy, the control was 56 patients of the same age with type 2 diabetes mellitus and the absence of diabetic retinopathy and other ophthalmopathology at present and in the anamnesis.

[Prevalence and detection rate of senile cataract in individuals with cardiovascular diseases].

Objective: To determine the prevalence of senile cataracts and its detection rate among the population at the age of 40 and older with diseases of the cardiovascular system.

Material And Methods: This observational cross-sectional study was based on the information extracted from electronic health records (EHR) of patients aged 40-99 years assigned for medical services to a city polyclinic.

Results: Among the population with essential hypertension (EH) senile cataract occurs with the frequency of 10.

[Femtolaser-assisted phacoemulsification of intumescent cataract].

Purpose: To optimize the technique of intumescent cataract phacoemulsification by involving the use of femtosecond lasers.

Material And Methods: Group 1 included 29 patients (30 eyes) with mature intumescent cataract, who underwent femtolaser-assisted phacoemulsification using a new, optimized technique. Group 2 included 20 patients (20 eyes), in whom the femtolaser stage was performed using the standard technique.
