RESUMEN
Vitreous hemorrhage as a complication of Age-Related Macular Degeneration (ARMD) is not a frequent event: 19 cases (out of 18 patients) are reported, corresponding to 0.6% of the patients with ARMD seen in the Department of Ophthalmology of Créteil between January 1st, 1979 and December 31, 1986. The relation between ARMD and vitreous hemorrhage was easy to establish on fundus examination after the resorption of the hemorrhage. However, during the acute hemorrhagic phase, the diagnosis was helped by the other eye fundus examination: this second eye presented with ARMD lesions in 15 out of 18 cases (78.9%). The most challenging differential diagnosis was the choroidal melanoma, when a subretinal hematoma hindered all underlying structures. Vitreous hemorrhages originated generally from well developed subretinal new vessels (17 cases out of 19) arising from the choroid. A retinal pigment epithelium tear, spontaneous or secondary to photocoagulation, was suspected to be the cause of the vitreous hemorrhage in one eye. Finally drugs (3 cases) and systemic diseases (6 cases) seemed to play a role. Visual prognosis is poor in most cases, as the result of the destruction of the macular photoreceptors (six eyes only retained a visual acuity equal or better than 20/400). Laser photocoagulation of the subretinal new vessels was possible for 5 eyes and allowed stabilisation of visual acuity in 2 eyes and improvement in one eye. Vitreous hemorrhage cleared in 16 out of 19 during the follow-up period and vitrectomy was therefore not performed in our series and not indicated at early stages.

The authors present two new visual tests for preschool children: the Cadet letters and the Cadet images, work of the Cadet (Cercle d'Action et de Dépistage des Troubles visuels de l'enfant). The Cadet lettres prospects the angular acuity of children on and after three years. The Cadet images prospects the psychomorphoscopic visual acuity of children on and after two years.

We studied the degree of inflammatory reaction after 43 non-complication intracapsular cataract extractions with anterior chamber lens implantation. Two types of implants were used that varied only by the shape and composition of their loops. Inflammation was more frequent and more severe with polypropylene loops. However, the degree of the inflammatory reaction did not interfere with the final visual results. The anatomic position of the loops did not noticeably influence the degree of inflammation but did seem to affect the final visual acuity.

The prevention of symblepharon formation in severe ocular burns can be achieved simply, innocuously and economically, by the application of hen's egg allantoic membrane. Three cases of burns caused by tear gas, sulphuric acid and quicklime were treated by this procedure. The operative procedures, including the membrane preparation and dissection techniques, and methods of applying this membrane to the eye are described. The various advantages of this very old technique, which is apparently not very well-known, are discussed.
