中文摘要 | 目的:在於測量有早產兒視網膜病變病史之學齡前兒童,其屈光度數及眼軸長等參數。方法:於板橋亞東醫院,收集56位3至5歲兒童的右眼,共56隻眼睛,以自動驗光機測量睡狀肌麻痺後之屈光度數,以IOLMaster測量眼軸長、前房深度、及角膜弧度,以IOLMaster中之Haigis formula計算水晶體之度數,有早產兒視網膜病變病史者為第1組(28隻眼),其中有接受視網膜雷射治療為第1A組(14隻眼),無接受視網膜雷射治療且自行痊癒為第IB組(14隻眼),足月產者為第2組(28隻眼),各組間數值之比較方法,以nonparametric Wilcoxon rank-sum test統計。 結果:各組間之眼軸長及年紀並無統計上之差異(p>0.05),第1、2組比較後,第1組之屈光度較偏向近視、前房深度較淺、角膜弧度較陡峭、水晶體之度數較高(p<0.05)。第1A、1B組比較後,第1A組之近兩見較深及水晶體之度數較高(p<0.05)。結論:有早產見視網膜病變病史之學齡前兒童之近視,並非眼軸較長造成,而是因為前房深度較淺、角膜弧度較陡峭、水晶體之度數較高導致。有早產兒視網膜病變,且接受視網膜雷射治療病史者,與未接受視網膜雷射治療且自行痊癒病史者比較,前者之近視及水晶體度數較高。 |
英文摘要 | Purpose: To evaluate the refractive and biometric values of preschool children with retinopathy of prematurity (ROP).Methods: We collected data of the right eye of 56 preschool children from 3 to 5 years of age at Far Eastern Memorial Hospital, Taipei, Taiwan. Cycloplegic refractions were measured by automated refractometer, and biometric data were measured by the IOLMaster (Carl Zeiss Meditec AG, Jena, Germany). The Haigis formula was employed to predict lens power. Patients with ROP were categorized as Group 1 (28 eyes), and those with full-term history as Group 2 (28 eyes). Group 1 was further divided into Group 1 A (14 eyes), severe ROP treated by laser ablation; and Group 1 B (14 eyes), spontaneous regression of ROP without intervention. Refractive and biometric data were compared between groups and subgroups by using nonparametric Wilcoxon rank-sum test.Results: There were insignificant difference in axial length and age between groups and subgroups (p>0.05). Group 1 had more myopic refractive error, shallower anterior chamber depth, steeper corneal curvature, and higher lens power compared with Group 2 (p<0.05). More myopic change and exaggerated biometric findings were found in Group 1 A than in Group 1 B (p<0.05).Conclusion: Myopia in preschool children with ROP was not axial myopia, which was attributed to steeper cornea, shallower anterior chamber, and higher lens power. Myopia and abnormal biometric results were more exaggerated in eyes with laser-treated ROP than in those with spontaneously regressed ROP. |
