To describe a specific Greenlandic type af age-related macular degeneration (AMD) - the Retinochoroidal Atrophy (RCA).
135 referred patients in East Greenland were examined in 1997. A colour and a redfree fundus photograph of an 87-year-old Greenlandic woman illustrates the clinical picture of RCA (retinochoriodal atrophy).
Of 135 examined patients 22 had AMD. 23 eyes in 12 patients had RCA, which was the most common type af AMD in this Greenlandic investigation. The clinical picture of RCA is peripapillary and central retinochoroidal atrophy and sclerosis resembling a recumbent Russian matúshka doll. The mean age of the 12 patients with RCA was 74.4+/-8.7 years. They were all severely visually handicapped with a visual acuity < or =6/60.
A specific type of Greenlandic AMD called RCA is described. No epidemiological conclusions can be drawn from this investigation.
描述一种特定类型的格陵兰年龄相关性黄斑变性（AMD）——视网膜脉络膜萎缩（RCA）。
1997年对135例转诊至东格陵兰的患者进行了检查。一张87岁格陵兰女性的彩色眼底照片和无赤光眼底照片展示了视网膜脉络膜萎缩（RCA）的临床症状。
在135例接受检查的患者中，22例患有AMD。12例患者的23只眼睛患有RCA，这是此次格陵兰调查中最常见的AMD类型。RCA的临床症状为视乳头周围和中央视网膜脉络膜萎缩及硬化，类似于平躺的俄罗斯套娃。12例患有RCA的患者平均年龄为74.4±8.7岁。他们均有严重视力障碍，视力≤6/60。
描述了一种名为RCA的特定类型的格陵兰AMD。本次调查无法得出流行病学结论。
