[Acanthamoeba keratitis. Clinical, histological and ultrastructural study].

Acanthamoeba keratitis is a rare but very severe necrotizing stromal keratitis due to a non-parasitic free-living soil and freshwater amoeba. It affects more readily soft and hard lens wearers. It is often clinically mistaken for herpetic keratitis because of the similarity of the signs and the difficulty in performing the specific microbiological tests. This is the reason why the diagnosis is most often made at the time of penetrating keratoplasty and histological study of the buttons with special stains. Medical treatment is effective only when starting at the beginning of the disease.

[Surgical treatment of eye wounds with retinochoroidal metal foreign bodies. Apropos of 6 cases].

Six cases of intra-ocular metallic foreign bodies located into the retino-choroidal wall are presented. A surgical treatment was performed, and included a vitrectomy, a foreign body extraction with intraocular forceps, a primary or a secondary scleral buckling for the peripheral wound, and a retino-choroidectomy for one of the posteriorly located foreign bodies. In all the cases, we observed a cicatricial retraction of the retino-choroidal wound. When the wound was peripheral, the retina detached in the cases without buckling and it was necessary to do a secondary scleral buckling procedure. When the wound was located at the posterior pole, the retina remained flat in one case, with a 6 mm metallic body, probably because of the relaxing retinotomy performed to extract the foreign body. We think that it is better to perform a primary scleral buckle of the peripheral wounds. The various aspects of the treatment are discussed.

[A monocanalicular stent with self-stabilizing meatic fixation in surgery of excretory lacrimal ducts. Initial results].

Our experience of 49 cases with a new monocanalicular silicone stent is described. This is a stent with a "auto-stable" meatic plug which respects the canalicular anatomy. There is no stopping-knot, no palpebral ring as in the bicanaliculo-nasal-intubation. The risk of accidental exteriorization is less important, the risk of stricturotomy is absent. Two types of intubation can be used: monocanaliculo-nasal intubation: the way of putting it in place is the same as the bicanaliculo-nasal one, with a metallic probe. The range of it's use widdens from distal canalicular wounds (2 cases) to common canalicular stenosis (15 cases) and to lacrimo-nasal imperforations (12 cases). In the two last instances, the intubation is made through the superior canaliculus, so that the inferior one is left free. In 13 cases, an intubation was made bilaterally for the same disorder, and a comparison could be done between monocanalicular and bicanalicular intubation. The true monocanalicular intubation, for proximal injuries: grasping the metallic probe inside the nose is no longer necessary. The length of the silicone probe is adaptated intra-operatively. The functional results of monocanalicular intubation are comparable to the results of bicanalicular intubation, especially for monocanalicular injuries (in addition with canalicular sutures) and the lacrimo-nasal imperforation. Incidents were observed especially with the first patients; a strict method is mandatory for avoiding accidents. The use of monocanalicular intubation should be used only for short duration and monocanalicular disorders. In other cases, bicanalicular intubation remains the good choice.

[Repair of recent canalicular wounds using a monocanalicular stent].

A new monocanalicular stent is described, which is used in cases of lacrimal canalicular injuries, associated with direct sutures of the canalicular wall. When injuries occur on proximal portion (2/3) of the canaliculus, a true monocanalicular stent is used, without intubation of the vertical part of lacrimal system. When the distal portion (1/3) of the canaliculus and/or the sac are involved, a complete monocanalicular probe is placed. First results of this method are exposed (5 cases) and are suggestively good.

[Follow-up care of a bilateral nasal catheter. Incident management].

A review of the follow-up care of the silicone intubation is analysed. Details are given for the management of complications such as: vanishing of the probe, exteriorization, splitting of the canaliculus... A scheme of post-operative history is given, with consideration of tentative treatments.
