Possibilities of monitoring intraocular pressure in children using EASYTON transpalpebral tonometer.

Purpose: To compare the effectiveness of transpalpebral scleral tonometry (TPST) and corneal pneumotonometry in children, and assess the discomfort level when measuring intraocular pressure (IOP) by these methods.

Methods: TPST using EASYTON tonometer (Russia) and pneumotonometry using Reichert 7 Non-contact AutoTonometer (USA) have been sequentially performed on 84 eyes (42 children aged 5-14, ave. 9.

[Objective parameters of accommodation in concomitant strabismus].

Purpose: To develop an objective method of determining binocular accommodative response (AR) and concomitant accommodation in patients with strabismus.

Material And Methods: The study included 34 patients (68 eyes) with concomitant horizontal strabismus aged 6 to 32 years. The parameters of accommodation were measured using open field Binocular Auto Ref/Keratometer Grand Seiko WR-5100K (Grand Seiko Co.

[Prognostication of a complicated course of myopia in children].

The aim of the case study was to define the earliest criteria of the transformation of myopia into its aggravated form. Two related risk factors were isolated on the basis of a comprehensive examination of 135 children and teenagers with uncomplicated myopia of 0.5-16 d and with myopia complicated by different-type peripheral vitreochorioretinal dystrophies (PVCRD).

[Significance of lacrimal fluid peroxidation and anti-radical defense parameters for prediction and treatment of complicated myopia].

Study of lipid peroxidation and antiradical defense parameters in the lacrimal fluid from 270 eyes of children and adolescents with progressive myopia demonstrated a relationship between the development of peripheral vitreochorioretinal dystrophies and imbalance between antioxidant activity (AOA) of lacrimal fluid and intensity of radical formation evaluated by chemiluminescence (CL) intensity. The AOA/CL ratio is proposed as a reliable indicator for predicting the course of progressive myopia. A value < 30 indicates poor level of antioxidant defense of ocular media and tissues and is a prognostically unfavorable sign as regards development of peripheral vitreochorioretinal dystrophy.

[Contribution of biomechanical and hemodynamic factors to the genesis of chorioretinal dystrophies in myopia].

The bloodflow is decreased in myopic eyes with dystrophic changes in the center and at the periphery, this decrease being in proportion with the severity of the changes. Our study was aimed at elucidating the contribution of the scleral and hemodynamic factors to the genesis of myopic and chorioretinal dystrophies. A total of 295 patients with progressive myopia were examined.
