[Effect of phacoemulsification on the Berger space]
1Department of Ophthalmology, Affiliated Hospital of Nantong University, Nantong 226001, China.
Summary
Phacoemulsification can alter the Berger space (BS) structure, allowing fluid and material entry during cataract surgery. This study highlights the impact of surgical factors on the BS, emphasizing the need for careful technique.
Area of Science:
- Ophthalmology
- Surgical Science
Background:
- The Berger space (BS) is a potential anatomical space in the anterior segment of the eye.
- Its structural integrity and susceptibility to changes during ophthalmic procedures are not well-understood.
Purpose of the Study:
- To investigate the impact of phacoemulsification on the normal anatomical structure of the Berger space (BS).
- To identify factors influencing structural changes in the BS during cataract surgery.
Main Methods:
- Prospective cohort study involving 119 patients undergoing phacoemulsification.
- Slit-lamp microscopy and anterior segment optical coherence tomography (AS-OCT) were used for observation.
- Intraoperative AS-OCT, perioperative detection of BS and materials in the BS (MIB), and width measurements were performed.
Main Results:
- Phacoemulsification significantly increased the detection rate of the BS and MIB intraoperatively compared to preoperatively.
- The BS width decreased significantly postoperatively compared to intraoperatively.
- Zonular fiber weakness and higher cumulative dissipated energy were identified as risk factors for intraoperative BS structural changes.
Conclusions:
- Phacoemulsification can disrupt the normal anatomical structure of the Berger space.
- This disruption can lead to the intraoperative ingress of fluid and particulates into the BS.
- Surgical technique and patient-specific factors like zonular weakness are crucial in preserving BS integrity.

01:28Angle Closure Glaucoma: Treatment
648
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...

01:25Glaucoma: Overview
721
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...

01:16Focusing of Light in the Eye
3.2K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

01:27Open Angle Glaucoma: Treatment
542
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.
