Coat’s disease is a severe form of retinal telengectasia [idiopathic congenital vascular malformation], which typically affects one eye of boys in their first decade of life.
In early stages it is characterized by large areas of intra and sub retinal yellowish exudates haemorrhages associated with overlying dilated ad tortuous retinal blood vessels and a number of [...]
Retinal vasculitis

It is an idiopathic [cause unknown] inflammation of the peripheral retinal veins. It is characterized by recurrent vitreous haemorrhage; so also referred to [...]
Retinopathy of Prematurity
This is a bilateral proliferative retinopathy, occurring in premature infants with low birth weight who often have been exposed to high concentration of oxygen. This disease was earlier known as retrolental fibroplasia.

It is the name given to a condition in which the neurosensory retina separates from the retinal pigment epithelium (Normally these two layers are loosely attached to each other with a potential space in between).
What are the types of retinal detachment?
It can either be:
Primary or rhegmatogenous.
Secondary: this can be tractional or exudative

It is the primary pigmentary retinal dystrophy. Dystrophy stands for faulty nutrition. This is a hereditary disorder predominantly affecting the rods more than the cones. The rods and the cones are the end organs of vision also known as the photoreceptors. Rods sub serve the peripheral vision and vision of low illumination [scotopic vision]. Cones [...]
