TIGROID RETINA Meaning and
Definition
-
Tigroid retina refers to a distinct pattern or appearance of the retina, which is the light-sensitive tissue lining the back of the eye. This condition is characterized by the presence of alternating light and dark bands or stripes within the retina, resembling the stripes of a tiger's fur. It is also known as a tiger-striped retina.
The tigroid pattern is a result of abnormal pigmentation or deposits within specialized cells of the retina, called the retinal pigment epithelium (RPE). These cells normally play a crucial role in supporting and nourishing the retinal photoreceptor cells responsible for vision. In tigroid retina, there is a disruption in the normal arrangement and distribution of pigments within the RPE, leading to the formation of bands or stripes that appear lighter or darker than the surrounding retina.
Tigroid retina can be associated with various underlying conditions, such as certain inherited genetic disorders, metabolic disorders, or even as a secondary finding in certain diseases affecting the central nervous system. The specific cause of tigroid retina can vary depending on the associated condition.
Clinically, the diagnosis of tigroid retina is usually made through a comprehensive eye examination, including the evaluation of the retina using imaging techniques like fundus photography or optical coherence tomography (OCT). Management and treatment options depend on the underlying cause and associated symptoms.

It comes from the Old English word "tigras", which has its roots in the Latin word "tigris" and ultimately from the Greek word "tigris". The term "tiger" is often associated with the animal's uniquely striped coat, hence the use of "tigroid" to describe a similar striped pattern.
