[Anisometropia and presbyopia: prescription of progressive lenses, a new approach].

Objective Of The Study: To show that anisometropia does not absolutely preclude the prescription of progressive lenses.

Materials And Methods: Forty-one anisometropes and presbyopes were selected for a prolonged trial of visual correction using progressive lenses. The congenital or acquired type of their anisometropia and its particular form were also studied.

[Prevention of retinal detachment in Wagner-Stickler disease. Comparative study of different methods. Apropos of 22 cases].

Prophylactic treatment in patients presenting Wagner-Stickler disease has not been yet well defined. We retrospectively studied twenty-two patients who had a retinal detachment on the first eye. Among the ten patients treated by peripheral confluent laser photocoagulation, five had a retinal detachment after a mean follow-up of fifteen months; with a 42% rate of spontaneous retinal detachment bilateralization, we can conclude that laser therapy has not been efficient.

[Macular edema caused by contraction of the posterior hyaloid in diabetic retinopathy. Surgical treatment of a series of 22 cases].

We have observed some patients with diabetic macular edema who did not respond to grid laser treatment and who improved with spontaneous posterior vitreous detachment or vitrectomy. These cases have a taut and glistening vitreo-macular interface. Three such cases are presented in detail.

[Posterior luxation of lens or implant: surgical treatment using a perfluorocarbon solution. Technique and results of 13 cases].

We used perfluorocarbon liquids in the management of 6 cases of posterior dislocation of the lens and 7 cases of (sub-) luxation of a posterior chamber intraocular lens (IOL). The perfluorocarbon liquid was injected into the vitreous cavity after complete vitrectomy, to bring back the lens or IOL to the posterior chamber where it can be easily removed. The main characteristics of perfluorocarbon liquids used in this indication are their high specific gravity and their good surface tension.
