Schwartz-Bartter Syndrome (SIADH): Excess ADH leads to water retention and dilutional hyponatraemia, with low serum sodium and osmolality but inappropriately concentrated urine.

Bartter Syndrome: Renal tubulopathy with hypokalaemic alkalosis, high renin and aldosterone, normal BP, and polyuria—mimics loop diuretic effect at the thick ascending limb.

Frederic Crosby Bartter (1914–1983) American endocrinologist. Defined Bartter syndrome, co-described SIADH, and advanced adrenal and renal physiology.

Augustus Desiré Waller (1856–1922) was a British physiologist who recorded the first human electrocardiogram (ECG) in 1887. His work laid the foundation for modern electrocardiography and inspired Willem Einthoven’s innovations.

Erich Seidel (1882–1946), German ophthalmologist. Described Seidel scotoma (1914): sickle/arcuate blind-spot extension in early glaucoma.

Mogens Stig Norn (1925–2023), Danish ophthalmologist. Introduced lissamine green vital staining (1973); chief editor Acta Ophthalmologica (1975–88).

Manuel Straub (1858–1916), Dutch ophthalmologist. Early human fluorescein corneal staining (1888) and landmark lens-induced uveitis work

Lester T. Jones (1894/95–1983), Oregon ophthalmologist. Defined the lacrimal pump, created Jones fluorescein dye tests, and pioneered CDCR with the Jones tube.

Theodore Ernst Obrig (1894–1967) pioneered cobalt-blue and fluorescein viewing (1938), transforming contact lens fitting and corneal surface assessment.

Paul Ehrlich (1854–1915), German physician. Pioneer of chemotherapy; fluorescein eye studies, immunology, and Salvarsan for syphilis.

Ernst Pflüger (1846–1903), Swiss ophthalmologist. Early fluorescein cornea experiments (1882) and influential work on refraction, optotypes and colour vision testing

Henrik Sjögren (1899–1986), Swedish ophthalmologist. Defined keratoconjunctivitis sicca and described Sjögren syndrome; introduced 1% rose bengal staining (1933).
