[The appropriateness of our therapeutic attitude to expulsive hemorrhage].
Documented data on etiopathogenicity and treatment of expulsive hemorrhage are reviewed and a case reported. Validity of a new therapeutic approach to this lesion was confirmed after treatment consisting mainly of posterior choriodialysis combined with a wide Z-shaped scleral incision.

[Corneal incision in inverse step (author's transl)].
The author presents a corneal incision similar to that of Charleux, but the "biseau" was replaced by a step. Thus the wound is easier closed by the intraocular pressure because the thin posterior plane is moulded over the irregularities of the superficial plane easier than the short slope of Charleux's incision. As a proof, without reducing the postoperative security, the suture consists only of 3 points -- thus inducing a favourable influence on the cicatrisation --, the knotting force is diminished -- avoiding thus the risk of thread cutting the tissue, and the conjunctival covering is rarely used -- leaving thus the entire draining way of the aqueous humour unaffected. The 80 patients operated on left the hospital in the 4th day (41%), 10th day (50%) or in the 14th-21st day (9%), with satisfactory late results: visual acuity superior to 5/10 (87%) and astigmatism inferior to 1D (89%).
[Tenoplasty by marginal scleral division (author's transl)].
The author proposes a new technique consisting of lengthening the tendon of the hyperactive muscle by means of two small superficial scleral longues positioned at two extremities of the insertion, each being 1.5 to 2 mm in width and having a length that varies according th the degree of deviation to be corrected. The tendon is cut level with the sclera, between the two scleral tongues. Results in 27 cases were favorable (residual deviation of less than 10 degrees) in 70 p. cent of cases after one tenoplasty operation and 85 p. cent after a repeat tenoplasty. The length of the tenoplasty and the effect obtained vary with the type of strabismus: for each millimetre of tenoplasty the resulting correction is 2.2 degrees in monocular strabismus, 2.7 degrees in alternating strabismus, and 3.3 degrees in residual strabismus.
The pathogenic classification of glaucomas.
On the basis of a pathogenic definition, our classification distinguished for each of the first intersections a main--mostly determinant mechanism and a secondary mechanism, mostly modulating the damages: hydrodynamic alteration and tissue resistance alteration--for the second intersection, outflow block and hypersecretion--for the third. Reflecting the state of present knowledge, from the corresponding forms of the disease, only outflow block glaucoma is completely analysed, the exogenous, trabecular, pretrabecular and mixed glaucomas being described. In order to permit the correct framing of all pretrabecular block glaucomas, the posterior push forms (retrovitreal or parietal) were introduced besides the anterior already described forms (pupillary or angular). As for low tissue resistance glaucomas, genetic, cardiovascular, metabolic, haematologic and ocular influences are mentioned. This classification avoids the theoretical inadvertencies of previous classifications offering the synthetic frame of a coherent system, open to any new developments, all inclusive, terminologically clear and with direct therapeutic references.
