[Lymphographic and morphological studies of the conjunctiva in onchocerciasis patients in Liberia].
Conjunctival lymphographies in patients infected with Onchocerca volvulus in Liberia showed normal or only slightly dilated lymphatics. The light-microscopical studies of conjunctival specimens revealed microfilariae predominantly in edematous dilated interstitial channels. Microfilariae in lymphatics and interstitial channels without endothelium of the conjunctivae were demonstrated by scanning and transmission electron microscopy. No signs of inflammatory cellular reaction were found in the vicinity of the parasites. In conclusion, the dilatation of lymphatics and interstitial channels as well as the pathways along which the microfilarial penetrated the cornea and the anterior segments of the eye are discussed.
