研究目的: |
验证干眼患者 “脂质层变薄→透明圈异常→泪液高渗” 的病理关联,明确泪液结晶图外层透明圈在不同严重程度干眼中的特异性形态特征,建立其与脂质层厚度、泪液渗透压的量化关联模型,评估该指标在干眼分级诊断与核心病理预测中的临床价值,最终形成一套适宜基层推广的可视化简易评估方案。 |

Objectives of Study: |
To verify the pathological correlation of "lipid layer thinning → transparent ring abnormality → tear hyperosmolarity" in dry eye patients, clarify the specific morphological characteristics of the outer transparent ring of tear ferning patterns in dry eye of varying severities, establish a quantitative correlation model between the outer transparent ring and lipid layer thickness (LLT) as well as tear osmolarity (Tosm), evaluate the clinical value of this indicator in the graded diagnosis and core pathological prediction of dry eye, and finally develop a set of visualized and simplified assessment protocols suitable for promotion in primary medical institutions. |

Inclusion criteria |
This study intends to recruit 136 subjects aged 50-70 years, with a 1:1 male-to-female ratio, and divide them into 4 groups (34 cases each) according to the severity of dry eye: the healthy control group, the mild dry eye group, the moderate dry eye group, and the severe dry eye group. Each group shall meet the corresponding inclusion criteria as follows: 1.The healthy control group requires an OSDI questionnaire score of < 13, no ocular surface abnormalities detected by slit-lamp microscopy, a non-invasive tear break-up time (NIBUT) of ≥ 10 seconds, a negative result (0 points) in corneal fluorescein staining (CFS, NEI grading method); 2.The mild dry eye group requires an OSDI questionnaire score of >= 13, a NIBUT of < 10 seconds, and a negative CFS result (0 points); 3.The moderate dry eye group requires an OSDI questionnaire score of >= 13, a NIBUT of < 10 seconds, and a positive CFS result (< 3 points, showing scattered punctate lesions without fusion); 4.The severe dry eye group requires an OSDI questionnaire score of >= 13, a NIBUT of < 5 seconds or immediate tear break-up, a strongly positive CFS result (>= 3 points, with visible fused lesions or diffuse staining), or accompanied by severe ocular surface symptoms and visual function impairment. All subjects must voluntarily sign the informed consent form. |

|
排除标准: |
所有组别受试者均需排除以下情况: 1.既往有眼部化学伤、热烧伤或近 6 个月内眼部手术史; 2.近 1 个月内佩戴过角膜接触镜; 3.患有翼状胬肉、急性结膜炎、活动期睑缘炎等影响泪液分泌的其他眼表疾病; 4.患有干燥综合征、甲状腺相关眼病、未控制糖尿病等未控制的严重全身系统性疾病; 5.近 2 周内使用过人工泪液以外的眼用药物或抗组胺药、抗抑郁药等影响泪液分泌的全身药物; 6.处于妊娠期或哺乳期; 7.无法配合完成相关检查; 8.以及无法在非刺激状态下采集到检测所需最小泪液量(通常 > 10 μL)或因采集困难引发反射性流泪、严重影响样本理化性质。 |
||||||||||||||||||||||
|
Exclusion criteria: |
All groups of subjects need to exclude the following conditions: 1. previous history of ocular chemical injury, thermal burn or eye surgery in recent 6 months; 2. wearing contact lenses in the past 1 month; 3. suffer from pterygium, acute conjunctivitis, active blepharitis and other ocular surface diseases that affect tear secretion; 4. suffering from severe uncontrolled systemic diseases such as Sjogren's syndrome, thyroid associated ophthalmopathy, uncontrolled diabetes, etc; 5. in the past two weeks, he has used ophthalmic drugs other than artificial tears or systemic drugs such as antihistamines and antidepressants that affect tear secretion; 6. during pregnancy or lactation; 7. unable to cooperate to complete relevant inspections; 8. and the minimum amount of tear required for detection cannot be collected in the non stimulated state (usually>10 μ L), or reflective tears are caused due to difficulties in collection, which seriously affects the physical and chemical properties of the sample. |
