[Ocular sarcoidosis]. / La sarcoïdose oculaire.

Sarcoidosis is a multisystem granulomatous disorder of unknown origin that most commonly affects young adults. Ocular involvement occurs in about 30% of patients. Acute or chronic anterior uveitis are the most common ocular manifestations of sarcoidosis but all the ocular tissues can be involved. Diagnosis is based on several investigations which the most interesting are biopsy of sarcoid granuloma and bronchoalveolar lavage. Treatment is topical or systemic corticosteroid therapy.

[Iridocapsular lenses: limbus versus pars plana approach in secondary cataract surgery (author's transl)]. / Lentilles irido-capsulaires: abord par le limbe et abord par la pars plana dans l'opération de la cataracte secondaire.

We operated on 55 eyes with secondary-cataract following implantation of a Binkhorst's irido-capsular lens. The procedure was through the limbus in 27 cases and via pars plana in 28 cases. For the limbus approach, we made a discission ("membranotomy") in all cases. By pars plana approach, we made a discission in 6 cases and an excision ("membranectomy") by means of phacophage (lensectomy instrument) in 22 cases. We observed that discission frequently yields deceptive or transitory results, requiring one or more reinterventions, while excision of the pupillary membrane by means of phacophage always results in a broad and definitive opening Pars plana approach has the advantage that it facilitates transformation of membranotomy to membranectomy. None of the 55 cases has presented retinal detachment.

[Keratoplasty. Urgent treatment of the corneal perforation (author's transl)]. / La kératoplastie. Traitement urgent de la perforation de la cornée.

Sixteen keratoplasties (15 perforating, 1 lamellar) were performed on 12 perforated corneas and on 2 eyes threatened by imminent corneal perforation. The causal disease was metaherpetic kératitis (6 cases), chronic and recurrent ulcers (4 cases), acute keratoconus (1 case) and corneal traumas (3 cases). Enucleation has been avoided and the anterior chamber was restored in all the cases, with or without anterior synechiae. One case only developed ocular hypertension which was cured by fistulisation. Architectonic results are satisfying in all the cases. Recuperation of visual functions is possible only in the most favourable cases. It is indicated to perform keratoplasty before the perforation when this one seems unavoidable and to consider this surgical procedrue as an emergency when the cornea is perforated.

[Implantation of Binkhorst's iridocapsular lens (author's transl)]. / Le choix d'une technique d'implantation d'une lentille intra-oculaire.

Advantages of the extracapsular extraction for implantation of Binkhorst's iridocapsular lens. Description of the surgical procedure; its indications and contre indications. Analysis of the results of 131 operations. The follow up of 120 patients exceeded six months. 84% of the patients have a visual acuity higher than 10/20. The major complication is secondary cataract which requires new surgery in 20% of the cases. The major complication is secondary cataract which requires new surgery in 20% of the cases. Other complications are the same as in classical intracapsular extraction when the indications of iridocapsular implants are correct.

[Implantation of intraocular lens in keratoplasty with cataract extraction (author's transl)]. / L'implantation d'une lentille intra-oculaire au cours de l'intervention combinée kératoplastie et cataracte.

A combined operation a) keratoplasty; b) cataract extraction; c) iridocapsular implant must be advised when a corneal opacity and a cataract require both a surgical treatment. Six months after surgery, functional results are good in 4 cases/5.
