To categorize and describe the type of optic disc involvement and blood vessel patterns seen in patients with fundus coloboma.
This is a prospective study involving 67 eyes of 40 patients with choroidal coloboma. The evaluation included documentation of fundus details using fundus drawings or photographs, or both.
Six types of disc involvement were identified: (1) normal disc outside fundus coloboma (27.8%); (2) disc outside the fundus coloboma and abnormal (10.4%); (3) disc outside the fundus coloboma and independently colobomatous (8.9%); (4) disc within the fundus coloboma and normal (5.0%); (5) disc within the fundus coloboma and colobomatous (44.3%); and (6) disc shape not identified but blood vessels seen emanating from the superior border of the large fundus coloboma (2.9%). Visual acuity was better in types I, II, and III compared with IV, V, and VI. Microphthalmos was more common with the more severe anomalies. High myopia was more common in the less severe anomalies.
Optic disc involvement in fundus coloboma is widely variable. Of fundus colobomas, 67.2% are associated with either a frankly colobomatous or an altered disc. Of the discs located outside fundus colobomas, 41% are also abnormal. Visual acuity was better in types I, II, and III.
对患有眼底缺损患者中所见的视盘受累类型和血管模式进行分类和描述。
这是一项前瞻性研究，纳入了40例患有脉络膜缺损患者的67只眼。评估包括使用眼底绘图或照片或两者记录眼底细节。
确定了六种视盘受累类型：（1）眼底缺损外的正常视盘（27.8%）；（2）眼底缺损外且异常的视盘（10.4%）；（3）眼底缺损外且独立存在缺损的视盘（8.9%）；（4）眼底缺损内且正常的视盘（5.0%）；（5）眼底缺损内且存在缺损的视盘（44.3%）；（6）视盘形状无法确定，但可见血管从大的眼底缺损上缘发出（2.9%）。与IV、V和VI型相比，I、II和III型的视力更好。小眼畸形在更严重的异常中更常见。高度近视在不太严重的异常中更常见。
眼底缺损中视盘受累情况差异很大。在眼底缺损中，67.2%与明显的缺损性或改变的视盘相关。在位于眼底缺损外的视盘中，41%也异常。I、II和III型的视力更好。
