The authors report about the results of a preliminary study concerning the changes of glaucomatous field after glaucoma filtering surgery in patients with advanced glaucoma. Mesopic campimetry had been selected because of its precision for central field defects. The first results appear to be favourable. No patient lost central vision suddenly after surgery. The authors have tried to research predictive risk factors. The factors that seem to be the most important to consider are the preoperative campimetric shape and the angle anatomy.

We report a case of central retinal artery occlusion following a minor ocular injury. The occlusions are an uncommon but well following some surgical operations on the eyeball, the eyelids or the nose. They probably result from an arterial spasm which trigger mechanisms are not very well known.

A new approach for the treatment of serious and/or uncurable glaucoma is proposed by the adjonction of a drain, cut in a crinotube, with micro-perforations and set in the classical opening of a trabeculectomy. In four years, for nine cases of particularly severe hypertonia, we observed one relative unsuccess, three real and stable improvements during two years and then with the necessity of local treatment (for rather young patients), and five clear and till today durable improvements. We have also observed a very good local tolerance for all cases, with never a persisting major hypotonia. This simple and efficient process seams susceptible to find its room in the treatment of severe hypertonia.

Perfluoropropane gas as an adjunct to vitreoretinal microsurgery in the management of proliferative vitreoretinopathy. Pure perfluoropropane gas was used as an adjunct to vitreoretinal microsurgery in 60 eyes of 60 patients with rhegmatogenous retinal detachment complicated by proliferative vitreoretinopathy. 0.3 ml to 1.8 ml (average 0.9 ml) of pure perfluoropropane gas were used. The surgical procedure included a vitrectomy and a scleral buckling procedure in all patients. The follow-up after complete gas absorption ranges from 6 months to 3 years in the successful eyes. Total retinal reattachment was achieved in 41 eyes (68.3%). The anatomical success rate was 88% (22/25 eyes) in grade C1-C2 PVR cases, 68.7% (11/16 eyes) in grade C3-D1 PVR cases, and 42% (8/19 eyes) in grade D2-D3 PVR cases. Visual acuity of 0.1 or better was achieved in 80% of eyes with grade C PVR and 61% of eyes with grade D PVR. Visual acuity of 0.4 or better was achieved in 26.9% of eyes with grade C PVR. Macular changes were revealed by fluorescein angiography in 53% of successful eyes. We recommend the use of C3F8 rather than SF6 in the management of rhegmatogenous retinal detachment complicated by PVR. In our experience the anatomical success rate achieved with C3F8 is approximately the same as that achieved with SF6. However permanent retinal reattachment was achieved with a single operation in 87.8% of successful eyes of the present series of patients manages with C3F8 as compared to only 12% of successful eyes of a previous series of patients managed with SF6.(ABSTRACT TRUNCATED AT 250 WORDS)

Authors relate a typical case of primary empty sella turcica. Its physiopathogenesis is not yet well known, ophthalmological manifestations are non specific and variable, and authors point out difficulties in treatment.

Nowadays, electro-oculography remains the only clinical method for ocular movement recording which is largely used in daily practise, but it has many drawbacks and limits. Till now the photo-oculographic technics have been only applied in laboratory conditions. A new differential photo-oculographic procedure is presented. This optical method is based upon the measurement of gaze direction and ocular movement amplitude from the relative pattern of five reflected corneal dots and pupil image which are located in two different optical plans. The authors relate in detail the recording devices and processing materials for the computerized analysis of video signals. The preliminary results confirm the real advantages of the method which allows to record all sorts of ocular movements in clinical conditions.
