Changes in Tear Protein Pattern after Photorefractive Keratectomy
PURPOSE. Changes in tear protein composition of patients who underwent photorefractive keratectomy (PRK) were analyzed. METHODS. Tear samples were obtained from 23 eyes of 23 patients immediately before PRK and on the fourth postoperative day with glass capillaries. Tear proteins were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Digital image analysis and evaluation of the densitometric data of the electrophoretic separations were done with BioDoc-Analyze. RESULTS. Analysis of discriminance found a significant difference in the protein patterns (p<0.001). This type of analysis of the electrophoretic densitographs uses all peak information simultaneously. A signifi…
Update and guidance on management of myopia : European Society of Ophthalmology in cooperation with International Myopia Institute
The prevalence of myopia is increasing extensively worldwide. The number of people with myopia in 2020 is predicted to be 2.6 billion globally, which is expected to rise up to 4.9 billion by 2050, unless preventive actions and interventions are taken. The number of individuals with high myopia is also increasing substantially and pathological myopia is predicted to become the most common cause of irreversible vision impairment and blindness worldwide and also in Europe. These prevalence estimates indicate the importance of reducing the burden of myopia by means of myopia control interventions to prevent myopia onset and to slow down myopia progression. Due to the urgency of the situation, t…
