First, we were looking if a correlation between the extent of ptosis and superior visual field defect exists. In a second step visual fields in blepharochalasis were compared with those in ptosis.
Pre- and postoperative visual fields in 20 patients with blepharochalasis, 6 patients with congenital and 9 with acquired ptosis were tested using program 7 of Octopus 500 automated perimeter. The degree of ptosis was separated in mild, medium and severe. According to the extent of visual field defect the same parameters as in ptosis were used also grading blepharochalasis in mild, medium and severe.
We found that the amount of upper visual field defect clearly correlated with the extent of ptosis. In addition, patients with congenital ptosis showed less visual field defect compared to those with acquired ptosis. Comparable to ptosis surgery blepharoplasty also lead in severe and medium cases to a clear gain of upper visual field.
Using perimetry and the same grading system as for ptosis makes it possible to study the functional defect occurring to the blepharochalasis patient.
首先，我们探究上睑下垂程度与上方视野缺损之间是否存在相关性。其次，比较了睑皮肤松弛症患者与上睑下垂患者的视野情况。
使用Octopus 500自动视野计程序7，对20例睑皮肤松弛症患者、6例先天性上睑下垂患者和9例后天性上睑下垂患者进行术前和术后视野检查。将上睑下垂程度分为轻度、中度和重度。根据视野缺损程度，采用与上睑下垂相同的参数，将睑皮肤松弛症也分为轻度、中度和重度。
我们发现上方视野缺损量与上睑下垂程度明显相关。此外，先天性上睑下垂患者的视野缺损比后天性上睑下垂患者少。与上睑下垂手术类似，睑成形术在重度和中度病例中也能明显增加上方视野。
使用视野检查法和与上睑下垂相同的分级系统，能够研究睑皮肤松弛症患者出现的功能缺陷。
