Atypical parafoveal telangiectasis with subsequent anterior and posterior segment neovascularization.

Bilateral parafoveal telangiectasis typically includes the presence of fluorescein staining of outer retinal capillaries, no macular ischemia, right-angled venules, and migration of pigment along these venules. In the bilateral form, atypical parafoveal telangiectasis with macular ischemia but without right-angled venules or migration of pigment along these venules has been reported in only five patients previously. An atypical case is presented of bilateral parafoveal telangiectasis complicated, not only by areas of macular nonperfusion, but also by peripheral ischemia with subsequent anterior and posterior segment neovascularization in the absence of any systemic abnormalities. As in previously reported cases, this patient had no evidence of right-angled venules or pigment migration. Pan-retinal photocoagulation resolved the rubeosis and caused regression of the retinal neovascularization.

Focal parafoveal retinal telangiectasis.

We describe four patients, two of whom are sisters, with an unusual form of retinal telangiectasis. The vascular abnormality is localized to the temporal parafoveal retina and is virtually identical in appearance in every patient. Other characteristics include: both men and women are involved, both eyes are generally affected, and symptoms develop in middle life. Laser photocoagulation succeeds in improving the visual acuity in the treated eyes. The consistency of the appearance and location, and the familial tendency indicates these cases probably form a subgroup of retinal telangiectasis.

Severe visual loss associated with retinal telangiectasis and facioscapulohumeral muscular dystrophy.

Facioscapulohumeral (FSH) muscular dystrophy is known to be associated with retinal telangiectasis. However, there are only few reports of severe visual loss due to exudative complications, so the risk to vision has not been established. Because of the possible therapeutic implications, we have described two cases of young girls who developed FSH muscular dystrophy and exudative retinal detachment due to telangiectasis. In the first patient, the severity of the disease precluded visual recovery despite extensive photo- and cryotherapy. In the other, visual acuity in both affected eyes was retained after treatment. Fundus examinations in young children at risk of having the gene for FSH muscular dystrophy may be justified so that retinal vascular disease can be detected before it becomes untreatable.

[Variable pseudoerythroplasic telangiectasis balanitis].

This is a special case of balanitis, that authors separate from entities clinically established such as Erthroplasie of Queyrat, Balanitis of Zoon, Liquenoide Balantis with Plasmocytes and the Balantis of Sulsberger and Garbe's illness. The V. P. T. B. is clinically characterized by the presence of telangiectasies, ertroplasiform aspect, without any infiltration, non purpure, the V. P. T. B. goes through a first period truly esythematous and a second one in which these is also desquamation. That cycle is completed in a month. At the histopathologic level, the most important characteristics are: epidermis with its Malpighian layer in a normal state, the basal layers showing hidropic degeneration. The repper dermis shows a lichenoid picture that, in certain places affects the basal layer. The infiltrate is composed of: lymphocytes, monocytes and plasmocytes. Numerous telangiectasies are also observed.

Capillary telangiectasis of the brain in chimpanzee.

The occurrence of capillary telangiectasis of the brain in a chimpanzee is reported. The telangiectases were multiple and diffusely scattered throughout the brain although the cerebral and cerebellar cortex were particulary affected. Hemorrhage into surrounding gliotic parenchyma was present. The were associated neuroligic sings, most significantly paralysis and convulsions, and the outcome was fatal. A Case of this nature has not previously been reported.

[Parafoveal retinal telangiectasis and changes of the capillary free zone in non-diabetic patients].

Microaneurysms, hard exudates, hemorrhages and/or edema in the macular region were observed in 10 eyes of 10 non-diabetic patients. By fluorescein angiography, parafoveal retinal telangiectasis was found in all cases. Deformation, enlargement and boundary disruption of the foveolar avascular zone were discernible in most cases, as were unevenness of capillary spacing, small areas of non-perfusion and leakage of dye in some cases. Analysis and calculations of the foveolar avascular zone were done with the Model-970 Quantmet computerized image analysis system. The data showed that the values of circumference, vertical diameter and roundness of the avascular zone differed significantly from those of the 10 normal control eyes.

Cystoid macular edema secondary to juxtafoveolar telangiectasis in Coats' disease.

A 28-year-old man with unilateral Coats' disease and cystoid macular edema secondary to juxtafoveolar telangiectasis underwent successful juxtafoveolar argon green laser photocoagulation therapy with resolution of the edema and improvement in metamorphopsia and visual acuity. Despite this success, the effect of laser therapy in these patients remains uncertain. It should be considered only after detailed discussion with the patient about the possibility of posttreatment paracentral scotomata and the alternative of a reasonable period of observation for possible spontaneous resolution of the edema.

Retinal telangiectasis: delayed response to photocoagulation.

A case suggestive of early Coats' disease treated cautiously with xenon arc photocoagulation is presented. Although adequate reaction was observed, the abnormal vessels persisted through the initial follow-up period. However, 9 months after treatment the vessels were found to be obliterated.

[Telangiectasis: arterial or venous?].

In this work we have tried to elucidate whether telangiectases are dilatations of the arteriolar or the venular sections of the circulation system. To this end, we have made use of resources which have allowed us to study in the first place, the wall of these small vascular dilatations and, in the second place, their content. Through our studies we could determine that telangiectases are originated by dilatation of the venular sector of the circulatory system.
