Two clinical cases of hematic infiltration of the cornea after severe ocular contusions are reported. Lesion of the cornea endothelium determines infiltration of the parenchyma with hemosiderin and hypofucsin, the products of hemoglobin break down. Metabolic activity of the cornea suffers, oxygen supply becomes insufficient and produces degradation of the cornea parenchyma with loss of the visual function. The affection is interpreted as a hemosiderosis process.
The present paper reports a clinical-statistical study performed on 92 patients with clinical ischemic optic neuropathy. For a better assessment of the results, the diagnostic data found in a test group were compared with those in a control group, made of patients suffering from inflammatory and toxic optic neuropathy. The data permitted the disclose of the statistically important characteristics of the arteriosclerotic optic neuropathy.
The authors discuss palpebral reconstruction in simple wounds frequently encountered, showing the types of wounds in which grafts are used, or neighbouring or distal cutaneous flaps, grafts.
The authors operated 20 eyes of secondary glaucoma, the angle being blocked by goniosynechias (obstructive glaucoma). All the eyes had a past history of 1-7 antiglaucoma operations by conventional techniques without lowering intraocular tension. The Benedikt operation was efficient in 3 of 10 eyes (compensation of less than 24 mmHg with medication); the La Roca technique in 3 of 7 eyes, and the Nesterov operation in none of the 3 eyes in which it was applied.
The present paper is an introduction to and information about information processing, the principal notions and mains of approach in ophthalmology. Part one is dedicated to a general presentation of computers, and information processing, giving details about the equipment, operating systems and programmes, data bases and their structure. Part two presents different aspects of the information processing involved in ophthalmology. The following applications are discussed: beginning by simple data collection and evidence for medical purposes, statistical processing, bibliography classification, teaching, continuing with problems of diagnosis and therapeutical decisions, as well as the application of medical robots and computer assistance for specific functional explorations.
The authors review the principal elements linked to the use of cortisone in ophthalmology, emphasizing new facts concerning the action of cortisone and especially the problems connected with this treatment.
Diverticulum of the lacrimal sac is a rare affection. The differential diagnosis must be established with angioma, dermoid cyst, exceptionally with a meningocele, all manifested clinical as a tumefaction of the internal palpebral angle. An individualized therapeutical approach is recommended.
Leukotrienes are polyunsaturated fatty acids, derive from arachidonic acid. Today they have acquired importance in biology as they are involved in the function of live organisms, especially in superior animals, in the tissues and organs and the eyes.
The authors present some of the most important data in medicamentous therapy in ophthalmology.
The author tries to change the opinion still prevailing today according to which any pigmentary retinopathy may represent a handicap to the descendants. Pigmentary retinopathy may have several etiologies--hereditary, sex-linked, dominant autosomal or recessive autosomal, metabolic, within the framework of various mucopolysaccharidoses, secondary post inflammatory or post traumatic. Hereditary transmission is discussed recalling for isolated cases the empirical calculus of H. Maumenee on 1000 Swiss families. Genetic advice, the same as other medical prognosis must form integral part of clinical medical practice. Genetic advice must be based on perfect knowledge of the patient and his family, yet the final decision remains with the family.
