简介：
Overview
This study presents a novel ocular translaminar autonomous system (TAS) designed to regulate intraocular and intracranial pressures independently. By creating a translaminar pressure gradient, the system aims to mimic glaucomatous optic neuropathy for research on ocular diseases and conditions affecting intracranial pressure.

Methods Used
- Utilization of a translaminar autonomous system (TAS) for pressure regulation.
- Preparation of human eye samples to create a controlled experimental setup.
- Monitoring and calibrating pressure sensors to gather data on IOP and ICP.
- Inflow and outflow syringes were used for medium exchange and pressure management.
Main Results
- Successful establishment of average normal pressure differentials in the TAS model.
- Minimal pressure disturbances during fluid exchange, maintaining tissue viability.
- Observations included steady-state behavior of optic nerve head morphology across experimental timelines.
Conclusions

What advantages does the TAS model offer?
The TAS model allows for independent regulation of intraocular and intracranial pressures, which can lead to better insights into disease mechanisms.
How is the biological model implemented?
A human eye globe sample is prepared by removing the optic nerve sheath and vitreous humor, allowing for precise pressure control.
What types of data are obtained from the TAS system?
Data on intraocular and intracranial pressures as well as tissue viability and morphology observations can be collected in real-time.
How can this method be applied in future research?
It can be used to evaluate various ocular diseases and conditions tied to pressure anomalies, enhancing our understanding of their mechanisms.
Are there any key limitations to the TAS model?
One limitation could be the need for precise calibration and maintenance of pressure conditions to ensure accurate results.
What conditions could be studied using this model?
Conditions like glaucoma, traumatic brain injury, and idiopathic intracranial hypertension can be investigated using the TAS model.
How does the platform ensure tissue viability?
The medium in the tissue is exchanged every 48 hours with careful monitoring to minimize pressure increases, preserving morphology and function.
