[Results of early removal of intra-ocular silicone after vitreoretinal surgery].

Report of the anatomic results of early silicone oil removal in 23 eyes successfully treated by vitrectomy and silicone oil injection after membrane peeling. After cicatrization of retinopexy using panretinal photocoagulation, the silicone oil was removed. The retina remained attached in 87% of cases. The utility of laser retinopexy before silicone oil ablation is discussed.

A new method for the evacuation of aqueous humor in uncontrolled glaucoma. The vitreo-tenonian tube.

The vitreo-tenonian tube is a new procedure, used in uncontrolled glaucoma, for the drainage of aqueous humor. It presents three original characteristics: it is made of a stainless metal, it is implanted in the posterior segment after vitrectomy and it drains the aqueous humor in the subtenonian space. We will describe first the surgical technique for the implantation of the tube, and then we will present the results of the first eight cases treated by this method. The advantages and drawbacks of this type of drainage are discussed: they are compared with the other surgical techniques used in cases of glaucoma which is uncontrolled by the classical methods.

Late failures of trabeculoplasty.

The effects of trabeculoplasty, or Argon laser trabeculoretraction (A.L.T.R.) resulting from a study pursued over two years in 194 eyes, over 3 years in 45 eyes, and over 4 years in 22 eyes, show early and late failures. 151 phakic patients (76 women and 75 men aged between 25 and 93 with an average of 67 years) were treated. After a follow-up of two years we have an intra-ocular pressure (I.O.P.) drop of 6.93 mmHg and a failure rate of 28%; after a follow-up of 3 years the I.O.P. drop is 6.30 mmHg and the failure rate 36%; after a follow-up of 4 years the I.O.P. drop is 7.87 mmHg and the failure rate 41%. The initial medical treatment could be decreased in less than 50% of the cases. The frequency of failure is more important in the presurgical glaucoma with an intra-ocular pressure higher than 28 mmHg and submitted to maximum tolerated medical therapy. A.L.T.R. gives good results in combined mechanism glaucoma and after failure of trabeculectomy; a two-year follow-up shows similar efficacy in primary open angle glaucoma (P.O.A.G.) and in pigmentary glaucoma, bad results in myopic or in aphakic glaucoma (12 cases not included in this study) and 'escape' in pseudo-capsular glaucoma. The total study conducted over 4 years shows 10% new failure cases per year.(ABSTRACT TRUNCATED AT 250 WORDS)

Gas tamponade as a single technique in the treatment of retinal detachment: is vitrectomy needed? A comparative study of 120 cases.

Internal gas tamponade is employed with no episcleral buckle and can be combined with or without a vitrectomy for the surgical treatment of some forms of retinal detachment. These techniques are for forms of retinal detachment with no proliferative vitreoretinopathy that are being operated upon for the first time and have one or several breaks located on the superior half of the retina. We compare these two techniques, their anatomical results, and their complications.

Classification of diabetic retinopathy.

A review of the literature on the classification of diabetic retinopathy shows that a consensus of opinions is not attained. Therefore it is impossible to compare the results of different works. Most of the classifications are based on purely anatomical criteria (ophthalmoscopic or photographic). The authors propose to base the classification of diabetic retinopathy on angiographic criteria. They consider that only fluorescein angiography can take into consideration the functional evaluation of the retinal circulation with unquestionable pathogenic correlation and adapted treatment: edematous diabetic retinopathy corresponds to capillary dilatation and ischemic diabetic retinopathy corresponds to capillary occlusion. Macular diseases are classified according to these same criteria.

[Treatment by internal tamponade of retinal detachment with a macular hole].

The authors analyse the operative results of 92 cases of retinal detachment with macular hole, treated by internal tamponade, since 1976. Three technics were used: vitrectomy + silicone oil injection (75 cases), vitrectomy + SF6 gas injection (9 cases), intra-ocular liquid suction + SF6 gas injection (8 cases). Silicone vitrectomy is particularly advisable in the case of large, old retinal detachment with proliferative vitreoretinopathy. This form of treatment is imperative when there is no hope of a satisfactory postoperative positioning, or after an unsuccessful gas treatment due to epiretinal macular membrane. Suction gas is a new and simple technique which is recommended when the macular hole is isolated and without epiretinal membranes. A lattice pattern argon-laser retinopexy is performed, by means of a series of laser impacts at the posterior pole, up to the edge of the macular hole. Treatment of isolated macular holes in a flexible retina by silicone vitrectomy achieved a 78.5% success rate; suction + gas achieved a similar success rate; this last method appears to be the ideal first choice for most of the cases, i-c the two failures which were subsequently turned into successes by silicone vitrectomy.
