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.
A retinal tuft is a gliotic degeneration of the retina composed of focal adhesions in the extracellular matrix joining the retina and the posterior hyaloid of the eye. [4] [5] Retinal tufts are a common lesion of the retina and under 1% of these tufts are thought to lead to retinal detachment.
Intermediate uveitis is a form of uveitis localized to the vitreous and peripheral retina.Primary sites of inflammation include the vitreous of which other such entities as pars planitis, posterior cyclitis, and hyalitis are encompassed.
Retinitis pigmentosa (RP) is a member of a group of genetic disorders called inherited retinal dystrophy (IRD) that cause loss of vision. [1] Symptoms include trouble seeing at night and decreasing peripheral vision (side and upper or lower visual field). [1] As peripheral vision worsens, people may experience "tunnel vision". [1]
Other findings may include vessel and macular dragging, sub-retinal exudates, neovascularization, retinal folds, and retinal detachments. [1] FEVR must be differentiated from other diseases involving incomplete vascularization of the retina including retinopathy of prematurity (ROP), Norrie disease, Coat's disease, and others.
The retina (from Latin rete 'net'; pl. retinae or retinas) is the innermost, light-sensitive layer of tissue of the eye of most vertebrates and some molluscs.The optics of the eye create a focused two-dimensional image of the visual world on the retina, which then processes that image within the retina and sends nerve impulses along the optic nerve to the visual cortex to create visual perception.
Lattice degeneration is a disease of the human eye wherein the peripheral retina becomes atrophic in a lattice pattern. Usually, this happens slowly over time and does not cause any symptoms, and medical intervention is neither needed nor recommended.
Eales disease is a type of obliterative vasculopathy, also known as angiopathia retinae juvenilis, periphlebitis retinae or primary perivasculitis of the retina.It was first described by the British ophthalmologist Henry Eales (1852–1913) in 1880 [1] and is a rare ocular disease characterized by inflammation and possible blockage of retinal blood vessels, abnormal growth of new blood vessels ...
