Coats-like exudate
Yellowish retinal deposits resembling those in Coats disease, often associated with retinoblastoma. May mask underlying tumor on clinical examination.
Full Definition
Yellowish, lipid-rich exudative deposits in the retina that mimic the appearance of Coats disease but are associated with underlying retinoblastoma or other intraocular tumors. These exudates can obscure tumor visualization and complicate diagnosis, requiring careful differential diagnosis. The term is crucial for accurate clinical documentation and helps distinguish tumor-associated exudation from primary exudative retinopathy.
Usage
Usage note: Always hyphenate 'Coats-like' when used as a compound modifier. Capitalize 'Coats' as it derives from the eponymous disease.
