Photocoagulation was used to treat 40 eyes, 20 with central and 20 with branch vein occlusion. Panretinal photocoagulation was used over the fundus in central vein occlusion, and regional photocoagulation over the affected area in branch vein occlusion. No complications were observed during a follow-up period of 8 to 24 months. Recent as well as long-standing cases with macular edema were treated. Visual acuity improved in 85% of eyes with central vein occlusion and 80% of eyes with branch vein occlusion. Visual acuity results were more satisfactory with early treatment.
Ocular fundi of 410 newborns were examined for retinal hemorrhages within 24 hours after delivery. The purpose of this study was to investigate whether the course of pregnancy and management of delivery influence the incidence of neonatal retinal hemorrhage (RH) and whether this incidence could be reduced by electronic monitoring of delivery. To assess the prognostic value of neonatal RH for future development of the child, the physical, motor, and psychologic states of 252 infants were examined 6 to 18 months following delivery. The incidence of RH was 37.3% and was not influenced by maternal age, parity, gestational age, course of pregnancy, birth weight, or electronic monitoring of delivery. The mode of delivery did influence the incidence of RH. Gesell developmental schedule showed no correlation between ocular findings and later development of the child.

126 cases of retinal breaks treated in our department by photocoagulation during a period of 10 years (1963-1973) were selected for a close annual follow-up. Eliminated from the study were cases of macular holes, breaks which developed in an eye after retinal detachment surgery, and cases in which a close follow-up was impossible for various reasons. The study includes symptomatic retinal breaks in myopic, non-myopic, and aphakic eyes as well as asymptomatic holes which were found in the undetached fellow eye. Four eyes treated by photocoagulation (3.2%) developed a retinal detachment. The causes of failures and complications, such as retinal detachment, vitreous haemorrhage, and macular pucker, are discussed.
One man and 2 women, aged 67, 63 and 68 years, observed for 8, 6, and 2 years, developed a classical postoperative malignant glaucoma. After a second operation, the use of atropine drops was continued for 2 years in one case, whereas in the other 2 cases miotics and later acetazolamide (Diamox) were necessary in order to maintain normal intraocular pressure. All 3 patients refused a preventive operation in the fellow eye and the use of miotics proved both necessary and effective in maintaining normal intraocular pressure, normal visual acuity, and normal visual fields.
A 73-year-old woman underwent an uneventful intracapsular lens extraction. Two years later, an iris abscess, hypopyon, strong flare, corneal edema, and elevated intraocular pressure developed. Visual acuity diminished from 6/6 (20/20) with aphakic correction to hand movements. Gram-positive cocci sensitive to erythromycin and chloramphenicol were cultured from the anterior chamber. The hypopyon and the iris abscess reabsorbed because we administrated erythromycin at the beginning of the illness. Final visual acuity was 6/6 (20/20) and only a small hole remained in the iris at the site of the abscess. She was in good health four years later.
A brief description is given of the main clinical, histological and epidemiological circumstances of retinal vein occlusion. In an assessment of the pathogeneis of the condition, primacy is given to the role of arteriolar flow insufficiency and stress is laid on the long-standing capillaropathy which precedes the heamorrhagic phase of the disease. Basic therapeutic considerations are mentioned but stress is laid on the diagnosis of the pre-occlusive stage and on measures of a preventive nature that may be taken. Retinal vein occlusion and haemorrhagic cerebral infarct are compared with regard to their pathogenesis and the advantages are discussed of a common ophthalmoscopic study of retinal vein occlusion with neurologists interested in cerebral vascular disease leading to an interchange of therapeutic experience in both conditions. Finally, there are detailed the studies in retinal vein occlusion being conducted by the Jerusalem Institute for the Prevention of Blindness. These are studies of incidence, natural history and of pathogenesis as observed in the experimental disease produced in rhesus monkey.
The value of preoperative cultures, sensitivity tests and prophylactic preoperative antibiotic treatment was evaluated in a group of senile, uncomplicated lens extractions. Sulfacetamide or a mixture of chloramphenicol and polymixin were applied preoperatively for 1 week and an injection of penicillin and streptomycin was given postoperatively. A control group of 140 cases without treatment was also studied. No postoperative infections developed in either group. The number of pathogenic cultures was significantly smaller in the treated group as compared with the untreated one; the mixture of chloramphenicol and polymixin B sulfate was found to be superior to sulfacetamide, different clinical data was compared in the two groups. No postoperative infections developed in either group.
A 42-year-old man was injured twice in his left eye. The first injury resulted in a lacerated skin wound on the forehead, eyebrows and lids, a broken orbital wall and rim, and a small rupture of the sclera at 12 o'clock. The second injury caused a rupture of his left globe. During the operation a large scleral rupture, 1 mm from the limbus, a prolapsed iris, vitreous, and the lens were found under the conjunctiva. The would had been cleaned, the prolapsed iris and vitreous were excised, and the scleral wound sutured. One year after the injury the visual acuity was 6/10 with an aphakic contact lens correction and binocular vision was established. Diagnostic features and indications for immediate repair are discussed.
Two and half years after a circling buckle operation in which two Supra-mid sutures and a solid silicone explant were employed, a Pseudomonas infection developed around the explant and progressed to the inner eye. Removal of all implanted foreign material and treatment with Rifamicin saved the eye. The relevant literature on infection following sclero-plastic procedures is reviewed, and the pathogenesis of the late infections is discussed.
