A General Survey of Idiopathic Subretinal Neovascularization in Veterans General Hospital-Taipei

原因不明性視網膜下新生血管在台北榮民總醫院之調查

摘要


本文作者收集原因不明性視網膜下新生血管病例共廿八例,並發現疾病好發於四十歲以下病患。其發生率無性別差異,但女性似較早發病,病灶多產生於中央凹外,大小約小於視神經盤半徑,且好犯單眼。多數病患未接受任何治療,而其視力有減退現象,尤以病灶位於中央凹者更為顯著。一例曾接受鐳射治療,術後視力明顯改善。約二分之一病患有近視眼,其與疾病的產生有待進一步探討。

The authors reviewed the clinical records of their patients in Retina Clinic from September 1982 to July 1991. The patients with idiopathic subretinal neovascularization were evaluated each for the following criteria: age of onset, sex preponderance, bilaterality, size and location of neovascular membrane, visual acuity and refractive status. Of the 28 patients, 24 (89%) were under 40 years of age and 15 (54%) were female. Unilateral involvement was noted in all patients, of whom 16 (57%) had left eye being struck. Twenty (71%) patients had neovascular membrane less than 1/2 disc diameter and 21 (75%) were extrafoveal in location. Eleven (40%) patients had initial vision and ten (40%) had final vision less than 6/60. One patient showed improved vision after argon laser photocoagulation. Twelve (43%) patients were myopes with their refractive status ranging from -0.50 sph to -6.00 sph.
