眼科医生眼科眼科
玻璃眼研究研究玻璃眼研究
眼睛组织学眼睛组织学

背景情况:

轨道切除术是一种用于治疗青光眼的手术.
了解质组织的特性对于优化手术结果至关重要.
初级开角青光眼 (POAG) 和脑膜炎二次青光眼 (UG) 是不同的青光眼形式,需要手术干预.

研究的目的:

为了比较眼睛中的膜纤维的方向和结构性质,用POAG与UG对比.
为了研究POAG和UG患者进行轨道切除术的结膜组织学上的差异.

主要方法:

在轨道切除术期间,从29只眼睛 (17个POAG,12个UG) 中切除了膜.
结晶切割被染色为I型原蛋白 (COLI) 和α-平滑肌肉动蛋白 (αSMA).
使用共聚焦光显微镜和OrientationJ软件来量化纤维连贯性和能量.

主要成果:

在COLI和αSMA染色样本中,来自UG眼睛的状片显示出明显更高的连贯性 (纤维对齐),与POAG眼睛相比 (p < 0.001).
对于两种染色类型的UG眼睛,能量值 (定向信息大小) 也显著更高 (p < 0.001).
这些定量差异表明UG膜片的结构异构性更大,纤维方向更密集.

Glaucoma: Overview

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Open Angle Glaucoma: Treatment

Open Angle Glaucoma: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

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...
