ABSTRACT
The causes of late postoperative corneal endothelial decompensation in pseudophakic anterior chamber eyes with well placed intraocular lenses are not clear. The authors measured the degree of retrocorneal pigment dispersion and endothelial cell loss during six months, in a series of 27 anterior chamber pseudophakic eyes, operated more than one year ago, using a Konan wide-field specular microscope. A significant correlation was found between retrocorneal pigment dispersion and endothelial cell loss. A possible mechanism of this correlation is discussed: the retrocorneal pigment dispersion could be associated with rupture of the blood aqueous barrier. This rupture might be responsible for chronic low grade endothelitis. In current practice, retrocorneal pigment dispersion in anterior chamber pseudophakic eyes is an indication for half-yearly follow-up with specular microscopy, which may lead to an explantation of the anterior chamber lens.

Birdshot chorioretinopathy, also known as vitiliginous chorioretinitis, is a rare and serious retinochoroidopathy. We describe a case in a patient with long-standing typical psoriasis. To our knowledge this association has not been previously reported in the dermatologic literature. Both psoriasis and chorioretinitis appeared to respond to aromatic retinoids. The incidence of birdshot chorioretinopathy in patients with psoriasis should be assessed.

In 54 consecutive cases of glaucoma triple procedure, a trabeculectomy was systematically performed at six o'clock. By separating the order and the locations of the incisions as well as their placement in limbo-corneal sites, haemorrhages are minimized. A watertight, controlled running suture avoids post-operative flat anterior chamber, and permits rapid tonometric normalisation. The results of these first cases are: a mean post-operative ocular pressure (O.P.): 15.1 mmHg, mean drop of O.P.: 36%; tonometric normalisation and visual-functional improvement above 90%.

The purpose of this paper is to review causes and follow up of 16 patients who have had a keratoplasty "à chaud" for corneal ulceration, perforation, or reviving chronically abscess, with a 9 years follow-up for a first group, and 8 months for the second. In 58%, the graft remained clear, and in 16%, the acuity was 4 to 6/10 degrees. Keratoplasty "à chaud" seems to be the most efficient method for treatment of inflammation, the most radical to restore the integrity of the eye, and can give oftentimes an accurate optical result.
