[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. Pars plana vitrectomy with separation of the posterior hyaloid was performed in 22 cases. All of them had proliferative diabetic retinopathy, previously treated by panretinal photocoagulation. Fourteen cases had an ineffective macular grid laser treatment. Postoperative visual acuity was improved in 19 eyes and was unchanged in three eyes. The macular edema disappeared in 12 eyes and decreased in 10. Complications included a vitreous hemorrhage in 6 eyes, a paramacular tear in 1 eye, a reghmatogenous retinal detachment in 1 eye and cataract formation in 2 eyes. Vitreous surgery can improve the visual prognosis in cases of diabetic macular edema associated with a pathological vitreo-macular interface.

Retinal and choroidal ischemic syndrome, digestive tract and renal small vessel hyalinosis, intracerebral calcifications and phenotypic abnormalities: a new family syndrome.

A new family syndrome is described that affected three of seven siblings and another patient who had been abandoned at birth but came from the same area of France. All four patients were young women with a very peculiar phenotype, poikiloderma and greying of the hair, and idiopathic non-arteriosclerotic cerebral calcifications. Pathological studies demonstrated small-vessel hyalinosis due to basal membrane thickening, mainly in the digestive tract, kidneys and calcified areas of the brain. The clinical and biological expressions of these vascular changes varied. Peripheral retinal ischemic syndrome and chorioretinal scars were found in the ocular fundi of three patients. Malabsorption and protein-losing enteropathy was the main problem in all four, and was the cause of one patient's death. A subarachnoid hemorrhage due to a right sylvian aneurysm also occurred in two of the three sisters and was lethal for one. Nephropathy with renal failure and systemic hypertension is the major problem of the two surviving patients.

Study of a new series of large relaxing retinotomies.

Silicone oil injection followed by retinotomy was performed in a second series of 37 patients with retinal detachment and advanced proliferative vitreoretinopathy. The retina posteriorly to the retinotomy was attached in 16 eyes with at least 18 months of follow-up. Ambulatory vision or better vision was restored in 12 eyes. The size and the site of the retinotomy depend on the size and the site of the retraction.

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.

Localized retinectomy indications in the treatment and prevention of retinal detachment.

Retinectomy can be helpful in several cases: retinal inversion and giant tears when the edges are rolled up, and when vitreous strands are implanted on to pieces of the tear flaps; the approach to the subretinal area (subretinal glial strands, subretinal fluid drainage, subretinal foreign bodies); nondissectable areas of retinal retraction (retinal incarceration, vitreo-retinal proliferation, etc.). Most of these retinectomies have to be supplemented by vitrectomy followed by a silicone oil injection, with peroperatory cryotherapy or argon laser photocoagulation.

[Pars plana vitrectomy: causal affections, material employed, and approach in 1400 cases (author's transl)].

Isolated vitrectomy was employed in half of 1,400 cases operated upon, the other patients receiving an intra-ocular injection of silicone fluid. Emphasis is placed on the simplification undergone by the materials employed, the progress represented by the addition of an autonomous infusion for each instrument complementary to the vitrectomy, and the need for all ophthalmic surgeons, particularly those in training, to become familiar with the use of the vitreotome.

Treatment of epiretinal membranes: report of 40 operated cases.

40 patients with an operable epiretinal membrane were divided into two groups: patients of group 1 were operated without intraocular silicone oil, patients of group 2 were operated with silicone oil. The operation was carried out with simple instruments. The percentage of anatomic success (complete removal in 62% of cases) and functional success (increase of visual acuity in 58% of the cases) opens new perspectives in retinovitreous microsurgery.

[Results of oral glucose tolerance tests in 123 cases of senile cataract with associated glucose metabolism disorders].

Systematic oral glucose tolerance tests in patients due for operation for senile cataract revealed the presence of latent diabetes, undiagnosed by standard investigations, in 20% of cases. The proportion of diabetics in patients with cataract is abnormally high when compared to a population free from cataract (43% as against 16%), which is in favor of a diabetic condition being the cause of lens opacification. An H.G.P.O. is therefore justified in all patients over 50 years of age with cataracts, especially those that are bilateral and mainly cortical.

[Discussion of terminology concerning disorders of the optic nerve and disc (author's transl)].

Progress over the past few years in knowledge concerning disorders of the optic nerve and disc leads to changes in their classification. A new terminology is proposed. It uses a minimum of terms, their very general sense being understandable by any nonophthalmologist physician. It is based upon clinical symptoms and signs, thus being immediately applicable in clinical practice.

[Oedematous optic neuropathy from Perhexilline maleate associated with peripheral polyneuropathy (author's transl)].

The authors report on a polyradiculoneuropathy related to long-term treatment with Perhexiline maleate (a drug used in France since 1973 for coronary insufficiency) whose presenting sign is a bilateral aedematous optic neuropathy. The mechanism of this effect on the optic nerves and on papilloedema is discussed; it seems not to be caused by a direct toxic action on the optic fibres but by the existence of chronic intracranial hypertension.
