The association between relative peripheral refraction and myopia
摘要
Abstract
Objective To evaluate the relation between relative peripheral refraction and myopia. Method 90 Children (with 165 eyes included) at the age of 7~12 years old,who have attended to Pediatric ophthalmology clinic, Renmin hospital of Wuhan university in October 2016 to February 2017, were included in the study. Pe-ripheral refraction is measured to children. The 90 subjects with 165 eyes included were divided into three refrac-tive categories according to the spherical equivalent based on retinoscopic findings under cycloplegia: emmetropia group (n=27), low myopia group (n=112) and moderate myopia group (n=26). Peripheral refraction were mea-sured along 15 degrees and 30 degrees from central fixation in both nasal and temporal fields. The relative periph-eral refraction (RPRE) is described as the difference between peripheral refraction and central refraction. Results (1)There is significant difference in RPRE among the three refraction groups, the RPRE is increased from em-metropia, low myopia to moderate myopia ( <0.05).(2)As changing of fixation angles, it decreases progressively from temporal 30 degrees, nasal 30 degrees,temporal 15 degrees to nasal 15 degrees ( <0.05). The RPRE shows relative hyperopia in low and moderate myopia,which is greater at the surrounding retina than Macular center (<0.05)and is greater at the temporal fixating angles than nasal's with no statistical difference ( >0.05). Conclusions Peripheral retinal relative refraction statu shows relatively hyperopic that increases vary from emmetropia,low myopia to moderate myopia. RPRE in myopia is greater at the surrounding retina than Macular center and is ap-proximately equal between the temporal fixating angles and nasal's .关键词
