Influenza retinitis: association with influenza encephalitis.

PURPOSE: To report an unusual case of retinitis caused by influenza virus. CASE: A 30-year-old male claimed partial color blindness after recovery from influenza encephalitis. Visual acuity was 0.3 in the right eye and 0.03 in the left. An ophthalmoscopic fundus examination looked normal, but fluorescein angiography revealed granular hyperfluorescence with multiple dark circular lesions at the posterior pole of both eyes. Serological testing revealed an influenza A virus infection. With corticosteroid pulse therapy (3 days) followed by oral methyl prednisolone for 1 month, visual acuity gradually recovered. Over the following 2-year period, visual acuity has recovered to 1.2 in both eyes, but color sensation still remains impaired. CONCLUSIONS: Influenza encephalitis can cause visual loss due to retinitis at the posterior pole.

TM rats: a model for platelet storage pool deficiency.

TM rats have a light brown hooded coat pattern resembling that of Fawn hooded (FH) rats which are a model of platelet storage pool deficiency (SPD). We examined whether the TM strain has the same platelet SPD as the FH strain. TM rats had a prolonged bleeding time and a low blood serotonin level, although their blood coagulation time and platelet counts were normal. The light coat color of the TM strain was judged to be associated with the red-eyed dilution gene as in the FH strain, but not pink eye dilution as in the RCS rat strain. Platelet SPD seen in TM rats may be a pleiotropic effect of the red-eyed dilution gene proposed in FH rats. Despite these similarities, the genetic background of the TM strain was obviously different from that of the FH strain. The TM strain, developed independently of the FH strain, will therefore be used as a model of platelet SPD.

The heterozygote female in X-linked recessive primary retinal dysplasia.

Three families with primary retinal dysplasia are reported. The ophthalmoscopical findings vary from congenital retinal folds to highly disorganized tumor-like protrusions in the vitreous cavity. The family pedigrees along with the clinical features support an X-linked recessive mode of transmission for this condition. Female carriers for this gene may show retinal fold changes. In addition some of these presumed female carriers also demonstrated changes in the stroma of their irides resulting in a gray to grayish-blue color.

Color Doppler imaging of arterial blood flow in central retinal vein occlusion.

PURPOSE: The hemodynamics of the retrobulbar arterial circulation of patients with central retinal vein occlusion were evaluated in order to better understand the pathophysiology of this disease. METHODS: Color Doppler imaging was used to measure the peak systolic velocity and vascular resistance (pulsatility index) in the retrobulbar arteries of involved eyes and clinically healthy fellow eyes of patients with central retinal vein occlusion and in the control eyes of age- and sex-matched healthy volunteers. RESULTS: Average peak systolic velocity was significantly lower and average vascular resistance was significantly higher in the central retinal artery of involved eyes of patients with central retinal vein occlusion compared with clinically healthy fellow eyes and compared with control eyes. There also was a trend toward higher vascular resistance in the central retinal artery of clinically healthy fellow eyes of patients with central retinal vein occlusion compared with control eyes. In the ophthalmic arteries and short posterior ciliary arteries, vascular resistance was significantly higher in both the involved eyes and clinically healthy fellow eyes of patients with central retinal vein occlusion compared with control eyes. CONCLUSION: Color Doppler imaging parameters of the central retinal artery circulation were abnormal in eyes with central retinal vein occlusion, suggesting impaired arterial blood flow associated with this disease. The high vascular resistance in the central retinal arteries, ophthalmic arteries, and short posterior ciliary arteries of both involved and clinically healthy fellow eyes of patients with central retinal vein occlusion suggests that diffuse small vessel disease may predate and contribute to the development of central retinal vein occlusion.

The neuronal and extraneuronal uptake and metabolism of 3H-(-)-noradrenaline in the rabbit iris.

The disposition of 3H-(-)-noradrenaline (NA) was studied in the iris isolated from albino and pigmented rabbits. Pigment cells bind some NA, but do not metabolize it. Cocaine-sensitive neuronal uptake leads either to an extensive neuronal deamination of NA (when vesicular uptake is inhibited by pretreatment of the animals with reserpine) or to a pronounced accumulation of NA in the axoplasm (if, additionally, neuronal monoamine oxidase is inhibited). Corticosterone-sensitive extraneuronal uptake leads to O-methylation of NA by extraneuronal catechol-O-methyl-transferase. In the rabbit iris, there is no extra-neuronal deamination of NA. In contrast to findings with other tissues, the extraneuronal O-methylation of NA in the rabbit iris is not saturable.

[Combined thermal-photodisruptive iridotomy using the argon and neodymium:YAG laser].

With the combined thermal-photodisruptive laser technique a large iridotomy of controllable size can be performed without any major complications. Using the Wise 103 diopter contact lens, primary coagulation is performed with short-duration argon laser burns. Subsequently, multiple low-energy single pulses are applied with the Nd:YAG. The iris can thus be perforated step by step. Compared with the pure Nd:YAG laser technique, this procedure reduces the risk of bleeding. Compared with the pure argon laser technique, each iris can be perforated easily, regardless of its color and thickness. The present paper reports on experience gathered in a first group of 50 eyes.
