- 糖尿病视网膜病变研究研究
背景情况:
- 糖尿病黄斑 (DME) 是糖尿病患者视力丧失的主要原因.
- 早期干预对于管理DME和预防视力障碍至关重要.
研究的目的:
- 评估微脉冲激光 (SMPL) 治疗的疗效和安全性,以预防和管理轻度糖尿病黄斑 (DME).
主要方法:
- 一项前性,随机化,模拟控制的研究,涉及159只患有糖尿病视网膜病变和轻度DME的眼睛.
- 参与者接受了SMPL治疗或假治疗,在基线,3个月和12个月进行评估.
- 评估结果包括最佳校正的视敏度 (BCVA) 和光学连贯性断层扫描 (OCT) 参数,如中央视网膜厚度 (CRT) 和黄斑体积 (MV).
主要成果:
- 在12个月后,SMPL治疗导致BCVA显著改善,并减少了黄斑厚度 (MT),黄斑体积 (MV) 和高反射斑点 (HRS).
- 与假装组相比,SMPL组在3个月后显示CRT的下降更大,并且与假装组相比,救援治疗的需求明显减少.
- 虽然微动脉瘤计数在两组中保持稳定,但在假药组中,OCT参数和BCVA是稳定的.
结论:
- 低值微脉冲激光 (SMPL) 是一种安全有效的治疗方法,用于预防轻度DME.
- SMPL疗法有效地减少了黄斑的厚度和体积,保持了稳定的视力敏度.
- 对救援抗VEGF治疗的减少要求表明,SMPL可能会延迟或最大限度地减少在DME管理中对静脉内注射的需要.

Open Angle Glaucoma: Treatment
586
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
705
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
