[Uveitis and rheumatic diseases]. / Uvéites et affections rhumatismales.

Uveitis occurs among children suffering from juvenile chronic arthropathy (mainly in daughters presenting with the pauciarticular form and accompanied by antinuclear antibodies) and among adults in the group of seronegative spondylarthropathies, among which ankylosing spondylitis and Reiter's syndrome are the most representative diseases. The association between acute anterior uveitis, HLA B27 antigen and seronegative spondylarthropathies is discussed.

Corneal endothelial cell density in acute angle-closure glaucoma.

The endothelial cell density of 44 eyes after an acute attack of angle-closure glaucoma is statistically lower than the cellular density of 174 control eyes. The decrease in endothelial cell density increases the risk of edematous corneal dystrophy, more specially after surgery (e.g. cataract extraction). The modifications in corneal endothelial cell density are compared with the alterations of the iris after a crisis of angle-closure glaucoma.

[Long-term study of endothelial cell density after penetrating keratoplasty. Comparative study of fresh and median-term preserved cornea]. / Etude à long terme de la densité cellulaire endothéliale après kératoplastie perforante. Etude comparative des cornées fraîches et conservées à moyen terme.

A retrospective specular microscopic study of 118 clear corneal grafts shows that the endothelium of these grafts is progressively destroyed during the two first years. The reduction of cellular density is rapid at the beginning of postoperative period, stabilizing after two years. The comparison of endothelial cellular density in fresh non selected grafts versus grafts preserved in culture seems to indicate a longer survival of preserved grafts. This study shows the utility of wide-field specular microscopy in the follow-up of clear corneal grafts. This technique furnishes useful information for postoperative management and long-term prognosis.
