[A case of multiple epitheliopathy associated with sub-retinal neovascularization].

Gass described the acute posterior multifocal placoid pigment epitheliopathy in 1968. The disturbance of visual function is generally temporary with subsequent recovery. We describe one case of peripapillary and macular neovascularization with decreasing visual acuity due to macular haemorrhage followed by a fibro-glial scar. The pathogeny of the syndrome can explain the possible neovascularization. Neovascularization has been more often described with serpiginous choroiditis.

[Terson's syndrome. Apropos of 7 cases].

We studied seven cases of Terson's syndrome, in association with bleeding in the subarachnoid space caused by rupture of vascular malformation or cranial traumatism. The association of rapid increase of intracranial pressure with subarachnoid hemorrhage could explain the development of a Terson's syndrome. The retinal hemorrhages associated with the vitreous hemorrhage are variable in morphology and topography. Pars plana vitrectomy has been performed in eight eyes with most often good results.

[Chorioretinopathy caused by migration of caterpillar hairs. Apropos of 2 cases].

Caterpillars cause many ocular lesions by a pathogen agent coming from their coating: the hairs. These can enter into the eye ball and migrate in the ocular tissues; a secondary inflammatory reaction to the foreign body will appear. This reaction is due to the hairs themselves as foreign body, but also partly to their contents: a liquid toxin which contains proteins, lipids and other components. The morphological configuration of the hair favours its migration in the tissues. Among the different lesions observed, chorio retinopathies are not very frequent, but their clinical aspect is quite characteristic and they are easier to recognize when they are associated with intra crystalline caterpillar hairs. Two cases of chorio retinopathies had been recorded. Both had hairs inside the lens and important hyalitis. One had the very characteristic "track-shaped" scars in the eye-fundus. The other had a focal chorio retinitis above the inferior temporal artery and developed a retinal tear. Local and general corticotherapy was applied, but the effect was not adequate. Vitrectomy was performed in the two patients with a good functional result. This seems to prove that vitrectomy may be useful for the important hyalitis secondary to the intra ocular migration of caterpillar hairs.

[Retinopexy by endodiathermocoagulation].

Retinopexy was performed by endodiathermy coagulation around a retinal tear provoked during dissection of epiretinal membranes. The dissection was a complement to vitrectomy for Candida albicans endophthalmia. The choice of this technique was dependent on the absence of need for the laser, and allowed an internal buffering to be carried out by the use of silicone oil. Angiography showed depigmented areas confirming the presence of scar tissue as seen in experimental rabbit studies. The scar involved the whole thickness of the retina and choroid adjacent to the cauterized pigmented epithelium. This method is simple and possesses the advantage of being able to be used when the perioperative laser beam is unable to cross the transparent media of the eye.

[Favorable development of bilateral Candida albicans endophthalmitis. Value of early vitrectomy].

A chronic bilateral endogenous Candida albicans endophthalmitis in a heroin addict was treated by vitrectomy, argon laser photocoagulation and endodiathermy. In the left eye with a visual acuity of 6/6 there was a totally asymptomatic retinal tear due to vitreous traction. The eye was treated by argon laser photocoagulation immediately, and then underwent a vitrectomy several weeks later. Analysis of the vitrectomy specimen was negative for any organism. In the vitreous of the right eye a "fungus ball" was noted nasally. Visual acuity was also 6/6. Fluorescein angiography demonstrated the presence of a small area of retinal involvement above the optic disc. During vitrectomy and membrane peeling the area of retinal involvement was torn away. The tear was then treated by endodiathermy. Vitreous analysis showed the presence of Candida albicans, sensitive to 5-fluorocytosine which was then used in treatment. All other cultures and stains were negative for Candida. The patient had negative serology for Candida, but normal immune responses based on cutaneous testing to several antigens and dosage of serum immunoglobulins and complement. A negative serology to Candida is most likely explained by the supposition that an episode of blood stream infection occurred only briefly and long before the eye involvement became clinically significant. At 4 months after bilateral vitrectomy, the patient has maintained 6/6 vision in each eye.

[A protocol for monitoring antimalarial treatment].

We are showing a protocol to survey the treatment by APS, with a computer equipment that enable us to examine very shortly the central field of vision and the ERG; but that least investigation can be EOG or a PEV, according to the toxic pathology we are studying.
