The spelling of the word "fundus tigre" comes from Latin root words meaning "bottom of the tiger," referring to the striped appearance of the fundus or the back of the eye. In IPA phonetic transcription, the pronunciation of fundus is /ˈfʌndəs/ and tigre is /ˈtiɡreɪ/, with an emphasis on the first syllable of both words. Proper spelling and pronunciation of medical terms such as "fundus tigre" are important for accuracy in diagnosis and treatment.
Fundus tigre is a Latin term that refers to a condition known as "tigroid fundus" in English. It is a medical term used to describe a specific pattern observed in the back of the eye or the retina. The term "fundus" refers to the interior surface of the eye that is visible during an eye examination. "Tigre" is derived from the Latin word for "tiger" and is used because the pattern resembles the stripes seen on a tiger's fur.
The tigroid fundus pattern is characterized by irregular patches or lines of pigmentation within the retina. These pigmented areas often appear in a network-like pattern, resembling the stripes found on the fur of a tiger. The pigmentation can range in color from light to dark, and the pattern may vary in intensity from person to person.
The presence of a tigroid fundus pattern can be an indicator of an underlying condition or disease. It is most commonly associated with a genetic disorder called Pelizaeus-Merzbacher disease, which is characterized by abnormal central nervous system development. Other conditions that may be associated with a tigroid fundus pattern include multiple sclerosis, metabolic disorders, and certain types of leukodystrophy.
Diagnosis of a tigroid fundus pattern typically involves a thorough eye examination, which may include the use of imaging techniques such as fluorescein angiography or optical coherence tomography. These tests help to visualize and assess the characteristic pigmented areas within the retina. Additionally, further investigations and medical evaluations may be required to determine the underlying cause of the tigroid fundus pattern.
