摘要:

The retinal correspondence was measured at several points of the binocular visual field in a case of anomalous correspondence. It was found that the anomalous correspondence was not limited to the foveae, but that there were pairs of peripheral anomalously corresponding points. The angle of anomaly was not constant over the binocular field. The correspondence was reciprocal at some points, non‐reciprocal at others. A comparison was made between normal and anomalous correspondence and the learning of anomalous correspondence was discusse

摘要:

Ten cases of malignant melanoma of the choroid, examined by fluorescein angiography and routine histologic methods, are reported, and correlation between the angiographic and microscopic findings is attempted.It is suggested that the fluorescent angiographic appearances in malignant melanoma are better understood in terms of the basic vascular patterns of the tumor as revealed by histology. In assessing the earliest patterns revealed by fluorescein angiography, the initial presence of a loose vascular network and the later appearance of fluorescent dots are readily understood if the histologic arrangement of the tumor vessels is borne in mind.The presence of wall‐less tumor blood channels and secondary changes such as hyaline degeneration of the vessel wall and tumoral cells are probably responsible for the late angiographic patterns and the residual fluorescence found in these tumors.The pigment content of the tumor, hemorrhages within the tumor, the presence of subretinal fluid, and vascular damage of the overlying retina are further variables which must be considered when interpreting the pattern of fluorescein angiography in this pathological conditio

摘要:

A 54‐year‐old man experienced sudden loss of vision of one eye and was admitted four hours later for treatment of typical occlusion of the central retinal artery. The patient died three weeks later and the autopsy revealed bronchial carcinoma of the epidermoid type with metastasis in most visceral organs. Microscopic examination of the eye disclosed the central retinal artery to be patent but with atheromatous changes at the level of the lamina cribrosa. The retina showed evidence of acute ischaemic infarction of the inner retinal layers. Tumour emboli were observed in the retinal arterioles. Trypsin‐digest preparations were also employed to demonstrate tumour cells in the retinal arter

摘要:

A case of conjunctivitis ligneosa which occurred in a girl aged 14 months and which was followed‐up for three years is described. The characteristic features of the disease are mentioned. It is concluded from the peculiar circumstance of the case having apparently undergone complete regression following a dental extraction, that the metabolic disturbance in the mucous connective tissue in the conjunctiva is precipitated by a nonbacterial focus via a possibly autoimmune mechanis

摘要:

A total of 220 inmates of old people's homes, all over 60 years of age, were examined for pseudoexfoliation of the lens capsule. The incidence recorded for the age group 60–69 years was 10%, 70–79 years 21.3% and 80–89 years 32.8%. The intraocular tension of the eyes with pseudo‐exfoliation averaged 17.5 mmHg, against an average of 15.4 mmHg in normal eyes. After mydriatics, pigmented floaters were seen in the aqueous humour of 61.5% of the normal eyes, and 83.3% of the eyes with pseudoexfoliation. In these latter eyes, moreover, the pigment liberation was distinctly more marked. The trabecular region of the affected eyes was more pigmented than that of the normal eyes. The mechanism by which pseudoexfoliation possibly affects pigment liberation and trabecular pigmentation is di

摘要:

Two patients with the clinical picture of a late infantile and juvenile amaurotic familial idiocy (Batten's disease) have been examined electron microscopically. The typical cytoplasmic inclusion bodies in the Schwann cells of the sural nerve supported this clinical diagnosis. The importance of sural nerve biopsy in patients with a cerebroretinal degeneration is discussed.

摘要:

Conjunctival sensitivity has been studied using Cochet&Bonnet's esthesiometer on a series of 102 normal eyes. Measurements were performed on 18 areas of each eye.The cornea was found to be the most sensitive, after which followed the lid margin. The caruncle was less sensitive, and the conjunctiva the least so. The mean values found in the stated four regions were 12 mg, 53–58 mg, 63 mg, and 83–96 mg per 0.0113 mm2, respectively.No local differences were noticed within the conjunctiva nor within the lid margin.Sensitivity declines appreciably with increasing age.The importance of considering the sensitive lid margin when fitting contact lenses is emphasi

摘要:

In a series of 102 consecutive patients with retinoblastoma, five were mentally retarded. These were classified as showing debility in two cases, and idiocy, imbecility and unclassified mental retardation in one case each. Three of the five patients had bilateral retinoblastoma and two had a positive family history for retinoblastoma. One of the patients had a congenital heart defect and another had a deformed skull. As occasionally retinoblastoma and a deletion of the long arm of a D‐chromosome are seen in combination with mental retardation, the present findings support the opinion that the association of retinoblastoma and mental retardation may represent a variant of the D‐deletion syndrome. Retinoblastoma patients deserve a complete physical and mental evaluation, and the ones exhibiting disorders merit cytogenetic stud

摘要:

Diffraction is generally regarded as the limiting factor of visual resolution, at least when the diameter of the pupil is less than 2.5 mm. This does not agree well with the clinical experience that it is not unusual for patients treated with miotics, who have a pupil diameter of less than 1 mm, to have normal visual acuity. A quantitative discussion of the diffraction pattern of a circular aperture and of the Stiles‐Crawford effect gives no adequate explanation of this discrepanc

摘要:

Yoga exercises caused prodromal attacks of acute glaucoma in a previously healthy patient with narrow anterior chamber angles. Attention is drawn to the “prone‐position” test, which was extremely positive. Ultra sound oculometry confirmed the shallow chamber and thick lens characteristic of primary angle‐closure glaucoma, and supported a gravitational shift of lens position in the prone p
