Refractive errors in children of Primorsko-Goranska County--epidemiological study

Three institutions: Teaching Institute of Public Health of Primorsko-Goranska County, Croatian Association "Albert Einstein" and Eye Clinic "Dr B.Vojnikovid" Rijeka agreed a five-year project to study children's health status of vision at Primorsko-Goranska County. Main task was the study of damage of vision in children due to prolonged sun exposure. Examination were conducted on a three locations, with the assumption of varying insolation: Island of Rab, Novi Vinodolski and Delnice. The study included children aged between 9 to 14 years. The study included 189 children. Except routine ophthalmologic examinations in addition were preformed biomicroscopic examination of the anterior segment of the eye, intraocular pressure and eye fundus. In a certain number of children with suspect of a specific disease (macular degeneration, glaucoma and refractive error), additional tests were performed: glaucoma treatment, field of vision, optical coherence tomography (OCT) of the eye and detailed eye refraction. This study specifically addressed of refractive error at that three different regions. It was found that the most difficult situation was at the Novi Vinodolski where as many as 40% of children have a refractive error, followed by Island of Rab with 17% and Delnice with 9%. Especially like to mention that on the island of Rab, 50-60 years ago, it was a very rare occurrence of some refractive errors in children.
