Translens Space

The postlenticular space (LPS) is a narrow gap filled with aqueous humor between the posterior surface of the lens body and the vitreous (ciliary) body.

Aqueous humor enters the PCP from the anterior chamber through the pupil, and its outflow occurs through the uveoscleral tract, which includes the trabecular meshwork. In the PCP, intraocular fluid is constantly exchanged with the tissues of the eye, thereby maintaining its constant composition and volume.

In the PCP there is a drainage zone, which is part of the uveosclera. Here, moisture is filtered through trabeculae, which form the trabeculo-canalicular system. In addition, the formation and removal of aqueous moisture occurs in the drainage zone.

PCD plays an important role in maintaining normal functioning of the eye. Thanks to it, an exchange occurs between intraocular fluids and tissue fluids of the eye, which ensures normal nutrition of the eye tissues, as well as the outflow of metabolic products.

Violation of the PCP can lead to various eye diseases, such as glaucoma, cataracts and others. Therefore, it is important to monitor the condition of the PCP and maintain its normal operation.

Transcrystalline space

The post-crystalline or lenticular-vitreous space is a slit-like (narrow) depression filled with aqueous humor. It forms between the posterior surface of the lens and the intraocular vascular complex. The presence of a small volume of refractive fluid in the lens space is very important for the normal functioning of the human visual system. If you look at the lumen of the eyeball using an ophthalmoscope, the membrane corresponding to the posterior pole of the fundus is clearly visible. A fossa is superimposed on this membrane - the place where the posterior capsule of the lens transitions into the vitreous body. The next well recognized is the narrowest place between the posterior capsule and the lenticular part of the vitreous body, associated with the transition of chamber moisture into the lenticular-vitreous pocket. But this is not all the optical structures of the eye. In it, both externally and in the internal membranes, there are a large number of other anatomical formations, including the presence of a lenticular pocket formed by the substance of the vitreous, lenses and the inner wall of the eye chamber. The lens pocket contains a certain amount of slightly transparent liquid (about 1.5 ml), which causes refraction and divergence of light rays when passing through it. This liquid acts as an insulator between the layers of crystal material. Between this liquid and the front surface, light rays are focused and pass through the transparent axis of the eye. Due to the fact that the lens sac has a small volume, moisture is constantly renewed and it never loses its properties.

In their composition, they differ significantly from those where there is a significant amount of pathological exudate. However, cholesterol crystals can be found in any effusion. Only their sizes differ. In the discharge from the conjunctival sac, these crystals occur only in the form of small
