摘要:

The Richner-Hanhart syndrome seen in a middle-aged woman is described. The patient had the typical clinical manifestations of tyrosinemia II with a bilateral keratopathy, palmar and plantar hyperkeratosis. The patient was subjected to a specific diet and to perforating keratoplasty. Postoperative systemic therapy with steroids had a negative influence on the clinical manifestations; dendritic lesions which developed on the corneal graft disappeared after interruption of the systemic steroid therapy. This suggests that cortisone treatment after keratoplasty should be avoided in this special metabolic disorder.

摘要:

Twenty-one patients, aged 4–42 years, with unilateral aphakia after perforating injury, were corrected with a combination of spectacles and contact lenses. While taking stereopsis and aniseikonia into consideration, each patient was corrected with the combination of contact lens and spectacles to achieve the best stereoscopic vision. Two of the five children (aged 4 and 7) achieved positive results on stereoscopic acuity. 15 of 16 patients (10–42 years old) showed good results on the TNO table test. The influence of visual acuity and age as well as the influence of the principles of the stereoacuity test are discussed.

摘要:

The Lens Opacity Meter 701 measures the lens density quantifying the back light scatter of the lens. The instrument emits a modulated dark-red beam which runs along the optic axis of the lens. The stray light is converted into an electrical impulse which is displayed and printed using a numerical scale. The lens density in a normal population was investigated with this instrument in order to study the influence of age on the opacification process.

摘要:

Between 1976 and 1985 81 cases of endophthalmitis have been treated by pars plana vitrectomy, and intravitreous injection of antibiotics or antimycotics. The functional results and the etiology of the endophthalmitis are discussed, as well as the reasons to perform a vitrectomy in endophthalmitis, and a possible explanation for the relatively high incidence of pseudophakic endophthalmitis is given.

摘要:

Fundus changes in sickle cell disease are well studied and documented according to their clinical and angiographic aspects. Sickle cell retinopathy was studied in a Brazilian population of 63 patients (41 with SS hemoglobinopathy, and 22 with SC hemoglobinopathy). All ophthalmoscopic changes observed in our patients were more frequent in the SC group with the exception of atrophic retinal tears, found only in the SS group. Proliferative retinopathy including its complications was seen in 54.54% of the eyes of the SC group, and in only 14.64% of the eyes of the SS group. Decreased vision is consequently greater in the SC group. Despite the great frequency of funduscopic changes in both groups, only 1 patient suffered irreversible visual loss due to retinal detachment operated on without success.

摘要:

A 54-year-old man with diabetes mellitus had abnormal choroidal vessels in the right eye. Whirled tributaries, the choroidal part of the vortex vein, and the scleral canal beneath the central foveal area were visible. This is a rare case of vortex veins in the macula.

摘要:

This study examines different clinical parameters and the occurrence of macular degeneration in a series of 110 patients with angioid streaks of the fundus. Among the parameters considered were: age of the patient at the time of ocular diagnosis, associated systemic disease, optic nerve drusen, peau d’orange appearance in the fundus, number of radiating angioid streaks as well as their length, width, and distance from the fovea. Statistically significant correlations were found between the occurrence of macular degeneration (of the exudative hemorrhagic type) and the following: angioid streak length, distance from the fovea, and the diffuse type or ‘cracked egg-shell’ fundus appearance.

摘要:

An 11-year-old Japanese girl had a greenish-gray, slightly elevated lesion at the optic disc and juxtapapillary retina of the right eye that was diagnosed as a combined hamartoma of the retina and retinal pigment epithelium. A gliotic epiretinal membrane partially covered the lesion. Tortuous retinal vessels, which leaked fluorescein dye, were noted ophthalmoscopically. The lesion remained stable during a follow-up period of 1 year. After reviewing the Japanese literature, we concluded that the combined hamartoma may not be as rare in Japan as previously thought.

摘要:

Absorbable polydioxanone (PDS; Ethicon) threads were used for cerclage of the eyeball. Experimental investigations on rabbits have proved that PDS is well tolerated by surrounding eye tissues, does not cause any side effects, and has a sufficiently long time of absorption to ensure chorioretinal cicatrization. 81.25% of reattachments were achieved in humans after the first operations, and 87.5% after the second operation. The authors conclude that PDS is good ocular cerclage material, but we would prefer it in the shape of a band.

摘要:

We report a new method of fluorangiography employing a polypeptide fraction from bovine factor VIII that has shown remarkable affinity to the endothelial surface of microvessels. Rabbits injected with this compound, labeled with fluorescein isothiocyanate, show a very delayed dissappearance time of fluorescence in retinal vessels when compared with those injected with ordinary fluorescein. This allows a good observation of the late time, which is of great diagnostic advantage for several pathological conditions.
