[Acoustic density of sclera as a prognostic factor of peripheral vitreochorioretinal degenerations in myopia: results of 10-years follow-up].

Prognostic value of acoustic density of sclera (ADS) is studied in development of peripheral vitreochorioretinal degenerations (PVCRD) in myopia. Children aged 8-10 years old with noncomplicated high and moderate myopia were divided into two groups after ADS measurement: 1 with ADS < or = 39dB - unfavorable prognosis, 2 with ADS >39dB - favorable prognosis. Follow-up during 10 years with examinations twice a year confirmed prognosis accuracy: in the 1st group PVCRD developed 2.

[On the contribution of cornea into accommodation of myopic eye].

To study the possibility of corneal contribution to process of accommodation in myopic eyes we examined 4 groups of patients: children and adolescents with low (1st group) to moderate (2nd group) myopia, young adults with moderate to high myopia after LASIK (3rd group) and PRK (4th group). Corneal optic power was measured using binocular open-field autoreferatometer in vertical and horizontal meridians for near (33 sm) and distant (5 m) fixation. No significant difference was found in children and adolescents with low and moderate myopia with intact cornea, as well as in young adults with moderate to high myopia after keratorefractive surgery.

[Acoustic studies of the sclera in progressive myopia in children and adolescents].

Acoustic density of the sclera (ADS) was examined using ultrasonic scanning device Ophthascan-B in 121 eyes of 91 patients aged 9 to 17 with progressive myopia of 3.5 to 14.0 diopters.
