Retinoschisis is an eye disease characterized by the abnormal splitting of the retina's neurosensory layers, usually in the outer plexiform layer.Retinoschisis can be divided into degenerative forms which are very common and almost exclusively involve the peripheral retina and hereditary forms which are rare and involve the central retina and sometimes the peripheral retina.
Retinoschisin also known as X-linked juvenile retinoschisis protein is a lectin [5] [6] that in humans is encoded by the RS1 gene. [7]It is a soluble, cell-surface protein that plays an important role in the maintenance of the retina where it is expressed and secreted by retinal bipolar cells and photoreceptors, [8] [9] as well as in the pineal gland.

Type 1 may be defined as an acquired capillary ectasia (a focal expansion or outpouching) and dilation in the parafoveal region, leading to vascular incompetence. Telangiectatic vessels develop micro-aneurysms that leak fluid, blood, and occasionally, lipid. Macular telangiectasia type 1 has been called as a variant of Coats' disease.
Cranioschisis (Greek: κρανιον kranion, "skull", and σχίσις schisis, "split") is a skull-related neural tube defect. The skull does not close all the way in this deformity (especially at the occipital region). As a result, the amniotic fluid enters the brain, leading to eventual brain degeneration and anencephaly.

Retinopathy is any damage to the retina of the eyes, which may cause vision impairment. [1] Retinopathy often refers to retinal vascular disease, or damage to the retina caused by abnormal blood flow. [2] Age-related macular degeneration is technically included under the umbrella term retinopathy but is often discussed as a separate entity.
Bitemporal hemianopsia is the medical description of a type of partial blindness where vision is missing in the outer half of both the right and left visual field. It is usually associated with lesions of the optic chiasm, the area where the optic nerves from the right and left eyes cross near the pituitary gland.
Synchysis scintillans is a degenerative condition of the eye resulting in liquefied vitreous humor and the accumulation of cholesterol crystals within the vitreous. It is also known as cholesterolosis bulbi.
Purtscher's retinopathy is a disease where part of the eye is damaged.Usually associated with severe head injuries, it may also occur with other types of trauma, such as long bone fractures, or with several non-traumatic systemic diseases.
