[Artificial crystalline lenses and Fuchs' syndrome].

Cataract removal with implantation of an intraocular lens (IOL) was performed in 36 cases of Fuchs' unilateral syndrome. --Intracapsular technique with anterior chamber IOL: 3 cases. --Extracapsular with IOL: 33 cases: Binkorst four loops sutured to the iris: 10 cases; posterior chamber in the sulcus: 12 cases; posterior chamber in the bag: 11 cases. The operative difficulties in such an indication consist in the constant hemorrhaging in the anterior chamber, the poor dilatation and the fragility of the zonule. Inflammatory reactions during the immediate post-operative follow up are frequently observed (22.2%) with pupillary deformations and Irvine Gass syndrome as complications. Glaucoma is a worrisome complication in its unusual frequency and by the poor results obtained by surgical treatment, but it does not seem to be directly related to the operation on the cataract. The complications which appear to relate directly to the implantation are represented above all by the risk in the long time, of lack of IOL transparency caused by the precipitates, and the aggravation of secondary vitreal disorders relating to recurrent cyclitis which is more frequent than in cases without implantation. The type of IOL implanted appears to have played no role on surgical results. Functional results were relatively good (83.3% having visual acuity superior or equal to 5/10). The restoration of satisfactory binocular vision justifies the risks of IOL implantation in cases of Fuchs' unilateral syndrome, but it is important to be forewarned of such an procedure risks.

[Traumatic cataract and implantation].

We report the results of with a ocular lens implantation in 132 cases of unilateral traumatic cataract. In most cases (130) the cataract was treated on using the extracapsular technique. Four types of intra-ocular lenses were used: Binkorst 2 loops implanted into the capsule (6%), Binkorst 4 loops sutured to the iris (18%), Anterior chamber implantation (19%), Posterior chamber implantation (57%). Implantation and cataract surgery were performed simultaneously in 85 cases (64.3%). Implantation was secondary in 47 cases (35.6%) implantation was performed as often in cases of contusion as in cases of perforating traumic, lens often in cases of intra-ocular foreign body. Implantation was usually primary in cases of contusion, now after secondary in cases of perforation. The most severe post operative complications are hypertony, corneal dystrophy (Binkorst 4 loops implantation and overall, anterior chamber lenses). Fonctional results in the child one 5 year old are about the same us in the adult. On the contrary in the child from 2 to 5, the results are bad because of the associated ocular lesions and fonctionnal amblyopia. In case of corneal associated lesions, it seems better to perform a primary implantation and eventually put the lens out of the center of the scar. Perforating keratoplasty must be reserved for cases of large central scotoma. In the cases of perforating trauma, surgery of the cataract must be differed if possible to allow simultaneous implantation.(ABSTRACT TRUNCATED AT 250 WORDS)

[Adenoma of the retinal pigment epithelium].

We report 3 cases of macular or perimacular adenomas of the R.P.E. These tumors are small, deeply pigmented and arise abruptly like a pyramid from a flat base over laying retina. There is no intra-tumoral vascularisation during angiography. They typically grow very slowly or not. Metastasis from them has never been described like a certainty with histological evidence. Clinical course, histological aspects are very similar to a carcinoma of R.P.E. They have a tubular or cord-like arrangement of proliferated R.P.E. cells. The main problem is to differentiate these tumors from first malignant melanomas and other uveal pigmented tumors and second others nonneoplastic proliferations of R.P.E.: essentially unifocal congenital hypertrophy and reactive hyperplasia. Management of these tumors depends of clinical characteristics and often behavior of the tumor with periodical photographic or ultrasonic supervision to detect evidence of growth which could lead to enucleation to obtain histologic evidence for fear of uveal malignant tumor.
