[Study of refractive changes inTimiş.county].

The aim of the study was to assess the prevalence of common refractive errors în children investigated at the "Louis Turcanu" Hospital's Ambulatory from Timisoara. This was a cross-sectional study done from January to June 2002 în the Ophthalmologic Medical Office. The target group was those of children from Timis County. We examined 646 children with a mean age of 10.7 years (from 0 to 18 years). A cycloplegic refraction examination was performed on all the children, using a computerized Humphrey-Zeiss autorefractometer. The statistical analysis was performed using CDC's Epi Info 2002. în the analysis, we used the Odds Ratio, the exact Fisher test and the chi-squared test. Among the 646 children, 407--63% (CI95 = 59.1-66.7) had refraction errors, of which 1.5% (CI95 = 0.8-2.9) were myopic whereas 49.8% (CI95 = 45.9-53.8) were hyperopic. Astigmatism was found în 11.8% (CI95 = 9.4-14.6). The study showed higher prevalence for the 14-16 age, emphasizing the importance of these examinations.

[Unilateral myelinated nerve fibers associated with myopia or amblyopia].

There are described a number of 9 clinical cases with unilateral myelinated nerve fibers, associated with myopia or amblyopia. Four cases developed extended myelinated areas, anisometropia with increased values, accentuated amblyopia and macular changes. Patients underwent treatment for amblyopia through correction with spectacles lenses and the occlusion of the congenerous eye. The obtained functional results differentiated the casemix in two groups: with therapeutic failure, 4 cases, characterized by extended myelination, anisometropia with an average of over -10 diopters and macular changes. with therapeutic success, 5 cases, characterized by reduced myelination, anisometropia with an average of over -4 diopters and normal maculae. It has been found a significantly statistical difference between the two groups as regarding the value of the anisometropia. However, the macular aspect has been an important factor in order the therapeutic effect to succeed. This clinical syndrome is differentiated from the unilateral simple myopia with amblyopia and from the myelinated nerve fibers without myopia or amblyopia.
