[Electrophysiological methods for examining preterm children and diagnosis of retinopathy of prematurity].

The first stage of the study was devoted to registration of visual evoked potentials (VEP) in 14 full-term and 27 preterm children without signs of neonatal retinopathy (NR) at the age of 6-7 months. The authors conclude that VEP in preterm children without signs of NR, born at different terms of gestation, reach the values of full-term children by the age of 6 months. These data should be taken account of when examining preterm babies for timely diagnosis of pathological changes in the visual analyzer and treatment. The second stage of the study was developed to registration of VEP and electroretinogram (ERG) in 36 children aged 4-12 years with cicatricial forms of NR. Changes in the central compartments of the retina were responsible for low visual functions in children with the cicatricial stages of NR. This abnormality is caused by displacement of the macular zone, impairment of its electrogenesis and topographic anatomic relationships. Examination of the marginal retinal periphery (superior external quadrant) once a year is obligatory for patients with cicatricial stages of NR in order to timely detect inapparent local fixed detachments or prevent them by timely prophylactic laser coagulation of the retina.

[Fluorescence angiography in the diagnosis of pathology of the fundus oculi in children].

Fluorescent diagnostics examinations were undertaken by the authors in different-age 410 children. The peroral fluorescent angiography (FAG) was used to examine 20% of cases, and the intravenous FAG was applied to 80% of cases. We offered the differential approach to dosing the solution, while making the peroral FAG examinations, which reduces the frequency rate of unfavorable reactions. The dosage ranged from 20 to 25 mg/kg with regard for purposes of examinations. The use of fluorescein did not cause any serious complications; nausea and a short faintness state were registered only in 10% of children. An examination of angiography images demonstrated that the phases of tinting of healthy tissue were identical to those tinted at the intravenous FAG. The below peculiarities of the child eye fundus were established: a weaker, as compared to the adults, pigmentation of the eye fundus, an insufficient differentiation of the macular zone and an immature peripheral retina in children during the neonatal period. Indications for FAG at congenital and acquired eye pathologies are specified.

[Prospects of using fluorescein angiography with oral administration of fluorescein in children].

Search for the subjective methods for the diagnosis of diseases of the fundus oculi in children necessitates the development of new methods. The authors are investigating the possibility of fluorescent angiography with oral administration of fluorescein with due consideration for the allergologic history and other conditions that may be contraindications against intravenous administration of the agent to children. Fluorescent angiography was carried out in 15 children aged 4 to 15. The procedure was well tolerated, no complications were recorded.
