"Phacoscotasmus" is a complex word used in ophthalmology to describe a pathological condition characterized by a fixed dilated pupil. The word is pronounced /fəkɒskəʊˈtæzməs/ with stress on the second syllable. The spelling of the word is derived from Greek roots "phako-" meaning lens, "skotos" meaning darkness, and "-tasmus" meaning stretching. This condition is commonly observed after cataract surgery and is caused by damage to the iris sphincter muscle. Correct spelling and pronunciation of complex medical terms are crucial in effective communication within the healthcare industry.
