## 一句话结论
球结膜水肿（Figure 1、Figure 2、Figure 3）的特征是清亮至淡嗜酸性液体积聚所致的弥漫性肿胀。

## 病变描述（中文）
球结膜水肿（Figure 1、Figure 2、Figure 3）的特征是清亮至淡嗜酸性液体积聚所致的弥漫性肿胀。临床上，结膜水肿称为 chemosis。它是一种非特异性病变，继发于局部刺激物、变应原、创伤和感染因子等原因。水肿区域可能存在炎性细胞。

## 诊断与分级建议（NTP 共识，中文）
结膜水肿应当被诊断并赋予严重程度分级。如果位于球结膜，水肿可在器官/亚部位“眼，结膜”下诊断。如果位于睑结膜，则可在“皮肤，眼睑”的器官/亚部位下诊断。如果继发于另一过程（例如炎症），结膜水肿不应单独诊断（除非严重程度确有必要），而应在叙述中描述。

## 英文原文 · Comment
Edema of the bulbar conjunctiva ( Figure 1 , Figure 2 , and Figure 3 ) is characterized by diffuse swelling due to accumulation of clear to pale eosinophilic fluid. Clinically, conjunctival edema is referred to as chemosis. It is a nonspecific finding secondary to such causes as topical irritants, allergens, trauma, and infectious agents. Inflammatory cells may be present in the edematous areas.

## 英文原文 · Recommendation
Conjunctival edema should be diagnosed and assigned a severity grade. If located in the bulbar conjunctiva, edema can be diagnosed under the organ/subtopography "eye, conjunctiva." If located in the palpebral conjunctiva, it can be diagnosed under the organ/subtopography of “skin, eyelid.” If secondary to another process (e.g., inflammation), conjunctival edema should not be diagnosed separately (unless warranted by severity) but should be described in the narrative.
