On a case of Günther congenital porphyria with late ophthalmic complications, the authors study clinical and haematological manifestations of this disease (clinical signs are related to light sensibilisation: sclerodactily, hyperpigmentation, non cicatrisating wounds, long standing scars of reposed areas; they begin in the early childhood by hemolytic anemia and emission of dark port urines too). The various porphyries are then studied and their ophthalmologic signs are related either to the light sensibilisation either to angiopathy and neuropathy (acute porphyria). These are always spontaneously reversible after the acute onset; on the contrary, light sensibilisation involvements go worth and worth and in some cases (Günther disease; late cutaneous porphyria) induce irreversible damages: they begin by eyelids and conjunctival scars then involve scleral and corneal tissues (scleral malacia perforans). In fact, they have a bad prognosis: ophthalmologic surgical repair, after a little success, fails, because of the non cicatrisating tissues. Best treatment is preventive: --in case of light sensibilisation: eviction of sunlight or light sensibilisating drugs; --in case of acute porphyria: eviction of some drugs (barbiturates); surgical action.

Radiological technique in the investigation of the lacrimal system has greatly benefited from various advances in radiology; techniques of catheterisation, contrast media, seriography, subtractions, associated complex tomography (dacryocystotomography), tomodensitometry. To these may be added the dynamic nature of isotope studies (cinegammadacrycystography). These different techniques may be used in the precise analysis of the morphology of the lacrimal system, from the canaliculi to the meatuses. After reviewing normal radiological anatomy, the authors describe morphological abnormalities, according to different forms of obstruction, according to their site. This morphological discovery requires possible changes in technique (additional tomography, for example). The quality of the preoperative morphological exploration influences the quality of the therapeutic results obtained.
