	Spectral Domain Optical Coherence Tomography System Optical Coherence Tomography (OCT) is based on light interference and measurements are typically non-invasive. OCT has the highest resolution compared to other tomographic medical imaging systems based on magnetic resonance, ultrasound or x-ray - even though a lower penetration depth. OCT is particularly well-suited for ophthalmic imaging, where high precision is required and the high transparency of the ocular tissues permit penetration back to the retina. Our custom-built sOCT system is equipped with a superluminescent LED with a central wavelength of 877.8 nm and a bandwidth of 62.5 nm. It has an axial resolution of 5.44 μm (in air) and a lateral resolution of 12.5 μm. The maximal A-line aquisition rate is 62 kHz and the maximal imaging area 14x14 mm.
	Intraocular Pressure Control Intraocular pressure (IOP) is a critical parameter in Ophthalmology. It is not only a diagnostic measure in Glaucoma, but also a confounding factor in determing corneal stiffness. Because of that, it is important to ensure a full control of the IOP during experiments. The pressure control unit consists of a syringe that is adjusted by a programatically controlled stepper motor. A tube system connects the syringe with a pressure sensor, and with the anterior chamber of the eye.
