摘要:

Ophthalmic manifestations were studied in 34 patients suffering from AIDS. Ophthalmic disorders were found in 20 of these (58%), the most frequent being a cottonwool-type spot (94.7%). Three patients showed an ophthalmic state compatible with choroid ischemia and atrophy of the pigmented epithelium of the retina. Three patients had necrotizing retinitis probably of viral etiology (cytomegalovirus). Other disorders observed were intraretinal hemorrhages, Roth’s spots, microaneurysms, periphlebitis and ocular infiltration by Kaposi’s sarcoma.

摘要:

Yellowish white precipitates are sometimes observed clinically in the subretinal area of the retinal detachments. We investigated retinal detachments observed in a 47-year-old man associated with choroidal malignant melanoma and in a 1-year-old girl with retinoblastoma. Yellowish white precipitates were foam cells located around degenerated outer and inner segments of photoreceptor cells. They were more abundantly present associated with malignant melanoma than with retinoblastoma. They exhibited abundant lipid droplets, abundant lysosomes with phagocytosed materials including inner segments, fibrin, melanin and lipofuscin, abundant glycogen particles, indented nuclei, and cytoplasmic processes without intercellular junctional apparatus. They appeared to be macrophages.

摘要:

A 4-year-old girl had a cavernous hemangioma of the retina in the right eye. A vitreous hemorrhage associated with this lesion caused amblyopic exotropia. Although this lesion has been considered harmless, it may cause visual impairment in the pediatric patients.

摘要:

In view of contrary reports in the literature on anomalies of taurine concentration in the blood of retinitis pigmentosa patients, taurine clearance has been determined in 19 patients and 17 controls. No significant difference has been found between the average values of the two populations. The taurine content in cataractous crystalline lenses of retinitis pigmentosa patients has been found higher than the taurine content in lenses with senile cataract, but the same behaviour was also shown by five selected proteogenic amino acids. The results are discussed together with related literature data to conclude that taurine can be involved at least in some subtypes of retinitis pigmentosa, but cannot be considered as a marker for the disease.

摘要:

Octopus visual fields were compared for three groups of patients: (1) diagnosed glaucoma patients; (2) glaucoma-suspect patients, and (3) control observers. Four visual field indices were analyzed for each visual field: mean sensitivity, short-term fluctuation (root mean square), mean defect, and corrected loss variance. Among the four indices, corrected loss variance was the only index that discriminated the glaucoma-suspect group from the control group, while, as expected, the glaucoma group differed from the other two study groups for all four indices. These data support the view that corrected loss variance may provide highly sensitive information on which to base an early clinical diagnosis of glaucoma in patients who do not demonstrate traditional field loss.

摘要:

Although corrected loss variance (CLV) may enhance the sensitivity of field examinations in the early stages of glaucoma, the value of CLV has not been investigated with advancing glaucoma. In this study we report mean defect (MD) and CLV for 266 Octopus field examinations (a total of 57 eyes and 47 patients with open-angle glaucoma) collected over a period of approximately 6 years on a stored database system. We find that CLV is generally elevated (relative to the normal controls) independent of MD. However, the elevated level of CLV does not vary with increasing field loss as indicated by MD. A classification system for defining stages of glaucoma is proposed utilizing CLV and MD as a combined index.

摘要:

In 303 patients (565 eyes) affected by ocular hypertension, an automated supra-threshold campimetry was performed using the «Moniteur ophtalmologique» with a video screen. An analysis of the visual field is presented. The sensitivity and the quality of the video screen are discussed.

摘要:

The present crossover, controlled study demonstrates that alcohol at a blood concentration of approximately 0.08% reduces the contrast sensitivity (p < 0.001). The mean contrast sensitivity was 15.03 dB in the control measurements and 14.39 dB in the measurements with alcohol. Brightness contrast sensitivity was measured with white, green, red and blue light, in this sequence. Therefore, the test design may present time effects as well as ‘color effects’. The mean decrease in contrast sensitivity was with white light ––1.26 dB, with green light ––0.88 dB and with red light ––0.57 dB. Contrast sensitivity tested with blue light showed even a slight increase with alcohol (+0.12 dB). The time interval between alcohol consumption and the test was important (p < 0.001). The mean decrease in contrast sensitivity with alcohol in subjects with a short interval of 40 min was less reduced (––0.3 dB) than in subjects with a long interval of 60 min (––0.98 dB). In summary, at moderate doses of alcohol, contrast sensitivity is only moderately decreased and this decrease depends on the time between alcohol consumption and the test.
