研究目的: |
1.总体目标 本研究旨在明确2型糖尿病酮症酸中毒(DKA)急性期对视网膜结构的特异性影响,描绘其恢复轨迹,并探索急性期眼底改变对远期糖尿病视网膜病变(DR)风险的预测作用,为临床个体化监测与干预提供依据。 2.具体目标 (1)量化急性期特异性损伤:利用SS-OCT及OCTA技术,通过与精确匹配的非DKA糖尿病患者对比,量化2型DKA急性期视网膜神经元(如GCIPL、INL厚度)及微血管(如SCP/DCP密度、FAZ形态)的特异性改变。 (2)揭示动态恢复规律:纵向追踪DKA患者从急性期至恢复期(6个月)的影像学变化,区分可逆性损伤(迅速恢复)与潜在不可逆损伤/重构(持续异常),明确“急性损伤-恢复-残留异常”的演变模式。 (3)探索远期DR风险的预测价值(探索性):在控制混杂因素后,初步分析急性期影像参数(变化幅度、恢复速度)与6个月DR进展的相关性。鉴于样本量限制,本部分旨在筛选候选生物标记物,为后续大样本研究提供假设生成,不构建临床即用的预测模型。 |

Objectives of Study: |
1. Overall Goal This study aims to clarify the specific effects of acute-phase diabetic ketoacidosis (DKA) in type 2 diabetes on retinal structure, outline its recovery trajectory, and explore whether acute-phase retinal changes can predict the long-term risk of diabetic retinopathy (DR), providing a basis for personalized clinical monitoring and intervention. 2. Specific Goals (1) Quantify acute-phase specific damage: Using SS-OCT and OCTA technology, and by comparing with carefully matched non-DKA diabetic patients, quantify the specific changes in retinal neurons (such as GCIPL and INL thickness) and microvasculature (such as SCP/DCP density and FAZ morphology) during the acute phase of type 2 DKA. (2) Reveal dynamic recovery patterns: Longitudinally track imaging changes in DKA patients from the acute phase to the recovery phase (6 months), distinguishing reversible damage (rapid recovery) from potential irreversible damage/restructuring (persistent abnormalities), and clarify the evolution pattern of "acute damage–recovery–residual abnormalities." (3) Explore the predictive value for long-term DR risk (exploratory): After controlling for confounding factors, preliminarily analyze the correlation between acute-phase imaging parameters (degree of change, recovery speed) and DR progression at 6 months. Considering the sample size limitation, this part aims to screen candidate biomarkers and provide hypothesis generation for future large-sample studies, rather than creating a ready-to-use clinical predictive model. |

纳入标准: |
1.DKA组 (1)年龄18-50岁(上限设为50岁以减少老年性眼底改变及白内障等屈光介质混浊的干扰); (2)2型糖尿病,符合DKA诊断标准(血糖 > 13.9 mmol/L,动脉血pH < 7.3,和/或碳酸氢根 < 18 mmol/L,血酮升高>3.0 mmol/L或尿酮阳性); (3)自愿参加本研究并签署知情同意书。 2.糖尿病无DKA对照组: (1)根据已入组DKA患者的年龄、病程、HbA1c分布,匹配对照组患者,确保两组在这些关键混杂因素上均衡分布。 附加纳入标准:符合2型糖尿病诊断标准(同DKA组标准),近3个月无DKA发作史。 |
||||||||||||||||||||||
|
Inclusion criteria |
1. DKA Group (1) Age 18-50 years old (upper limit set at 50 to reduce interference from age-related retinal changes and cataracts, etc.); (2) Type 2 diabetes, meeting DKA diagnostic criteria (blood glucose > 13.9 mmol/L, arterial pH < 7.3, and/or bicarbonate < 18 mmol/L, elevated blood ketones > 3.0 mmol/L or positive urine ketones); (3) Willing to participate in this study and sign informed consent. 2. Diabetes without DKA Control Group: (1) Match control group patients by age, disease duration, and HbA1c distribution based on the enrolled DKA patients, ensuring both groups are balanced on these key confounding factors. Additional inclusion criteria: meet type 2 diabetes diagnostic criteria (same as DKA group), no DKA episodes in the past 3 months. |
||||||||||||||||||||||
|
排除标准: |
1.DKA组排除标准: (1)存在严重屈光间质混浊(如白内障、角膜病变)或瞳孔无法散大,影响高质量眼底影像采集; (2)患有其他严重眼部疾病(如青光眼、年龄相关性黄斑变性、视网膜血管阻塞、葡萄膜炎等); (3) 有眼内手术史(如白内障手术除外)或视网膜激光光凝史; (4)合并严重心、肝、肾功能不全,或妊娠期妇女; (5)因意识障碍等原因无法配合完成眼科检查。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Exclusion criteria for the DKA group: (1) Severe refractive media opacity (such as cataracts or corneal disease) or inability of the pupil to dilate, which affects high-quality fundus imaging; (2) Other serious eye diseases (such as glaucoma, age-related macular degeneration, retinal vascular occlusion, uveitis, etc.); (3) History of intraocular surgery (excluding cataract surgery) or retinal laser treatment; (4) Severe heart, liver, or kidney dysfunction, or pregnant women; (5) Inability to cooperate with ophthalmic examinations due to consciousness disorders or other reasons. |
