Of 152 cases, 79.61% were males. Mean age at presentation was 11.4 ± 5.6 years. The characteristic PLP was present in 81 cases (53.29%; 95% confidence interval [CI]: 45.03%-61.42%; P < 0.001), of which 15 cases (18.5%) had this pigmentation in all the four quadrants. There was a significant difference between the groups with respect to quadrants involvement in terms of the extent of PLP in clock hours (χ2 = 73.85, P < 0.001). However, the extent did not correlate with age (rho = 0.08, P = 0.487), sex (P = 0.115), time since onset in months (rho = 0.03, P = 0.77), duration of VKC and type or color of PLP (P = 0.12).
Perilimbal pigmentation seems to be a consistent clinical finding seen in a significant number of VKC cases. It may benefit ophthalmologists in treating VKC cases when the palpebral/limbal signs are elusive.
■在152个案例中,79.61%为男性。演示时的平均年龄为11.4±5.6岁。81例患者存在特征性PLP(53.29%;95%置信区间[CI]:45.03%-61.42%;P<0.001),其中15例(18.5%)在所有四个象限都有这种色素沉着。就时钟时间的PLP程度而言,两组之间在象限参与方面存在显着差异(χ2=73.85,P<0.001)。然而,程度与年龄无关(rho=0.08,P=0.487),性别(P=0.115),发病时间以月为单位(rho=0.03,P=0.77),VKC的持续时间和PLP的类型或颜色(P=0.12)。
■Perilimbal色素沉着似乎是在大量VKC病例中观察到的一致的临床发现。当眼睑/角膜缘体征难以捉摸时,它可能有益于眼科医生治疗VKC病例。
