[Echocardiography and connective tissue diseases].

The aim of this study is to show the clinical value of the echocardiography in the heritable disorders of connective tissue, within a series of 10 cases, from 7,500 echocardiograms reviewed between 1978 and 1985. Echocardiography visualized an aneurysm of the ascending aorta in three patients, a dilatation of the pulmonary artery in one case, a mitral valve prolapse in six patients associated with an aortic and tricuspid valve prolapse in two cases, and a tricuspid valve prolapse and aortic regurgitation in one case. In two patients, an aortic valve prolapse was isolated. Other echocardiographic features were intracardiac calcifications (4 cases), septal hypertrophy (2 cases) and an incompetent foramen ovale (2 cases). Echocardiographic examination must be performed in all connective tissue diseases because cardiovascular complications are responsible for the vast majority of deaths. Conversely, all the patients with valvular prolapse, dilatation of the great vessels, aneurysm of the sinuses of Valsalva or congenital heart defects type incompetent foramen ovale should be suspected of connective tissue disorders. Such diagnosis is crucial when a surgical intervention is being considered because of the fragility of the tissues.

[Aniseikonia. A clinical study of 51 unilateral pseudophakic patients and practical applications].

The subjective aniseiconia was measured with spatial eiconometer on 51 isometropic and unilateral pseudophakic patients in relation with the post-operative anisometropia. The median value of subjective aniseiconia is 2-3% for anisometropia minus or equal to 5 diopters, without statistic correlation, related to a probably "sensorial brain adaptation". So error of intra-ocular lens power calculation less than 7.5 diopters may be accepted.

[Apparent accommodation of the aphakic eye corrected by an artificial lens].

We measured apparent accommodation in 51 pseudophakic eyes (44 patients, after implantation of anterior (15 eyes) or posterior (36 eyes) intraocular lens. Glasses for distant vision were born during the test. The mean apparent accommodation was 1.89 +/- 0.91 dpt. 25 among these 51 pseudophakic eyes who were tested without their glasses showed a mean apparent accommodation that was not different in statistical and clinical terms. The mean accommodative power of 25 phakic and presbyopic eyes used as controls was 1.31 +/- 1.01 dpt. For these 51 pseudophakic eyes the correlation between apparent accommodation and the reciprocal of the pupillary diameter is the most significant (r = 0.79): the smaller the pupil, the greater the apparent accommodation. There was a negative correlation between apparent accommodation and anterior chamber depth (r = -0.64). No correlation was found between pseudo-accommodation and corrected visual acuity, corneal astigmatism and refractive error.

[An unusual polymalformation syndrome: "CHARGE association" with unilateral "morning glory syndrome"].

Report of a case of the "CHARGE association" including bilateral papillary coloboma, with an aspect of "morning glory syndrome" on one side. Clinical features of the "CHARGE association" are described; pathogenesis is likely involving cells of neural crests. Discussion, in this field, of the ocular and systemic abnormalities associated with "morning glory syndrome".
