AIM To evaluate chronic ocular sequelae in patients with symblepharon caused by ocular burns and propose an objective grading system. METHODS This was a retrospective, single-center clinical study. Patients with symblepharon caused by ocular burns at least six months later were assessed. Chronic ocular sequelae were classified into 3 categories (eyelid, conjunctiva, and cornea) and 9 chronic ocular sequelae [friction factors, exposure factors, conjunctival hyperemia, length of symblepharon, scope of adhesion, lacrimal area adhesion, loss of the palisades of Vogt (POV), corneal neovascularization, and corneal opacification]. Each ocular sequela was graded from 0 to 3, depending on the increasing severity. The 9 ocular sequelae were evaluated to obtain the total severity score for each eye. The total severity score was defined as Grade I (1-9), Grade II (10-18), and Grade III (19-27). Moreover, the correlation between the severity of chronic ocular sequelae and visual acuity, surgical strategy, and the prognosis was analyzed, respectively. RESULTS Cases of 79 eyes with symblepharon caused by ocular burns were included in this study. Of these, 20 (25.32%) were defined as Grade I, 43 (54.43%) as Grade II, and 16 (20.25%) as Grade III. Eyes with a high total severity score had reduced visual acuity, required complicated surgery strategies, and poor prognosis (P<0.001). Multivariate regression analysis showed that the scope of adhesion, corneal opacification, and corneal neovascularization significantly affected visual acuity, surgical strategy, and prognosis (all P<0.001). CONCLUSION The evaluation of chronic ocular sequelae enabled the development of an objective grading system for patients with symblepharon caused by ocular burns. This grading system can be applied to guide the treatment and predict the prognosis.

眼灼伤引起的交趾腓患者慢性眼后遗症的评估。

目的评价烧伤引起的眼睑结节患者的慢性眼后遗症，并提出一种客观的分级系统。方法这是一项回顾性单中心临床研究。至少六个月后评估了因眼灼伤而导致的合掌龙的患者。慢性眼后遗症分为3类（眼睑，结膜和角膜）和9种慢性眼后遗症[摩擦因素，暴露因素，结膜充血，双指长度，黏附范围，泪腺区域黏附，Vogt的栅栏丧失（ POV），角膜新生血管形成和角膜混浊]。每个眼后遗症的严重程度从0到3分。评估了9个眼后遗症，以获得每只眼睛的总严重程度评分。总严重程度分数定义为I级（1-9），II级（10-18）和III级（19-27）。此外，分别分析了慢性眼后遗症的严重程度与视力，手术策略和预后之间的关系。结果本研究纳入了因眼灼伤而引起的79眼眼睑结节眼病例。其中，20级（25.32％）被定义为I级，43级（54.43％）被定义为II级，16级（20.25％）被定义为III级。总严重度得分高的眼睛视力下降，需要复杂的手术策略，预后差（P <0.001）。多元回归分析表明，粘连，角膜混浊和角膜新生血管形成的范围显着影响视力，手术策略和预后（所有P <0.001）。结论慢性眼后遗症的评估为客观性分级系统的开发，该系统用于由眼灼伤引起的交指突患者。该分级系统可用于指导治疗和预测预后。
