摘要:

Primary herpes simplex virus infection can cause an obstruction of the lacrimal canaliculi after canaliculitis and result in epiphora. Most patients are female, younger than 20 years of age and have an obstruction in the midzone of both the upper and the lower canahculus of one eye. 6 cases are reported and compared with previously described cases.

摘要:

73 consecutive aphakic retinal detachments were operated on by microsurgery combined with intra-operative biomicroscopic control of the ocular fundus. Retinal reattachment was achieved in 60 cases (82%), 59 eyes had only one operation. A visual acuity of 0.5 or better was achieved in 50% of all cases and in 57% of the cases which were not failures of previous conventional surgery. 69% of the eyes recovered the same visual acuity after surgery as before the occurrence of retinal detachment. One macular pigment migration and one cystoid macular edema were the only postoperative macular complications observed in this series.

摘要:

In clinical and in vitro conditions, the effect of intravitreously injected silicone oil upon the electroretinogram and electrooculogram was investigated. The recorded potentials were lower in the eyes with silicone oil compared to those in which the retinas were reattached without silicone. Retinal changes, caused by the previously existing detachment and the operations already performed, are discussed as possible factors responsible for lower values of the recorded potentials. No arguments could be found in favor of silicone retinopathy.

摘要:

Besides oxygen administration and immaturity of the premature retinal vessels, there are other risk factors for retrolental fibroplasia: (1) respiratory distress syndrome; (2) multiple episodes of bradycardia apnoea; (3) exchange transfusions; (4) hyaline membrane disease; (5) anemia of prematurity; (6) hyperbilirubinemia; (7) avitaminosis E; (8) cardiovascular defects; (9) infectious diseases; (10) multiple births; (11) hypocalcemia; (12) hypothermia; (13) hemorrhagic tendency; (14) delayed coaptation of the retina, and (15) spastic diplegia.

摘要:

The blood supply of the posterior optic nerve was investigated in 10 monkeys after an injection of synthetic resin into the carotid arteries. The posterior intraorbital and intracanalicular optic nerves were supplied by a centripetal vascular system, formed by the pial vessels arising from the first branches of the ophthalmic artery. Superior and inferior vascular semicircles were detected in the intracanalicular optic nerve. The intracranial optic nerve was supplied by branches of the internal carotid artery, anterior cerebral artery and/or anterior communicating artery, and ophthalmic artery.

摘要:

6 cases of Alport’s syndrome with ocular findings are presented and discussed. 4 cases had bilateral anterior lenticonus, one had retinal changes similar to the flecked retina syndrome and 1 case had posterior polymorphous corneal changes, a previously unreported finding. The varied ocular changes presented here all have in common a pathologic process involving the basement membrane or the specialized epithelium.

摘要:

Cystinosis is a rare autosomal recessive hereditary enzymopathy which leads to accumulation of cystine in the reticuloendothelial system of the liver, spleen, lymph nodes, etc. The pathognomonic alterations of the cornea are characterized by multiple crystalline deposits, chiefly in the limbus area and in the anterior corneal stroma. The retinal changes are seldom described in the literature; they are characterized by a fine-grained pigment shift which intensifies from the macula toward the preequator area and which gives the fundus a ‘salt and pepper’ appeara

摘要:

A papillary, white mass observed in a 45-year-old man was diagnosed as an optic nerve glioma. The histological examination revealed a juxtapapillary amelanotic choroidal malignant melanoma, extending over the optic disc and infiltrating the optic nerve. This clinical picture is quite infrequent in malignant melanoma of the choroid.
