High intraocular pressure in four vitrectomized eyes with intravitreal C3F8 without high altitude travel.

Importance: It is well known that altitude ascent with intravitreal gas can cause expansion of gas and intraocular pressure (IOP) elevation. According to Boyle's law, the gas bubble will not expand unless a higher altitude than the gas insertion site has been reached. We report four cases in which intravitreal gas was injected at an altitude of 790 m (Jerusalem).

Neonatal mydriasis: intravenous lidocaine adverse reaction.

Lidocaine (a sodium channel blocker) serves as an antiepilepsy drug in neonates. We present a neonate with a seizure disorder who acutely developed pupillary mydriasis secondary to lidocaine overdose. We suggest adding this side effect to the list of untoward effects of lidocaine and to the differential diagnosis of fixed dilated pupils in neonates treated with lidocaine.

The effect of normal childbirth on eyes with abnormalities predisposing to rhegmatogenous retinal detachment.

Background: Pregnant women who have high myopia, a history of retinal detachment or retinal holes, or have known lattice degeneration are frequently referred to an ophthalmologist for advice concerning the management of pregnancy and labor, i.e. whether a spontaneous vaginal delivery can be allowed and whether prophylaxis for high-risk retinal pathology is indicated.

Civil unrest and ocular trauma.

The incidence and causes of ocular trauma among Israeli troops serving in the West Bank and Gaza between 1987 and 1989 was investigated. Of the 985 soldiers who were reported injured, 11.3% (111) were reported to have suffered from injuries to the eye.

Multiple bone fractures following an epileptic seizure in renal osteodystrophy.

Seizure induced bone fractures in patients with renal osteodystrophy are uncommon. A case is described where multiple bone fractures occurred following convulsions which appeared shortly after haemodialysis.

Essential thrombocythemia: a rare case of central retinal artery occlusion.

Essential thrombocythemia is a myeloproliferative disorder with an increased amount of abnormal platelets, causing both hemorrhagic and thrombotic pathology. Some of its systemic complications include deep vein thrombosis, pulmonary emboli, myocardial infarcts, and renal vessel thrombosis among others. We present the rare case of a woman suffering from essential thrombocythemia with the sudden loss of vision in her right eye, caused by central retinal artery occlusion.

Optic disc drusen and hypermetropia.

We report the case of a 41 year old lady with high hypermetropia and optic disc drusen (ODD) in both eyes. A recent study has shown that ODD has a greater tendency to form in eyes with a small scleral canal. It would therefore seem probable to find a higher rate of ODD in hypermetropic eyes.

Retinal detachment with high myopia in the Rubinstein-Taybi syndrome.

A case of rhegmatogenous retinal detachment with high myopia is presented in a 17 year old boy with the typical characteristics of the Rubinstein-Taybi syndrome. Although multiple eye anomalies are known to occur in this syndrome, the occurrence of retinal detachment has not been reported up to now. The importance of including a thorough fundus examination in the routine eye examination of these patients is emphasized.

Legal aspects of work-related eye injuries.

As court-appointed medical advisors in the speciality of ophthalmology for the Israeli Labour Courts, we are called upon to assist in making decisions on work-related eye injuries or illnesses. In this report we present seven cases of eye injuries which workers claimed were caused by work accidents. Each case helps to illustrate the various guidelines we use in making a medical judgement as to whether or not a specific ocular problem was, indeed, the result of a work accident.

A new sling material for ptosis patients.

Patients with poor or total absence of levator function require correction of their ptosis by a sling procedure. The aim of the procedure is to utilize the action of the frontalis muscle, innervated by the seventh nerve, to mechanically raise the droopy eyelid. The most common materials used for the sling are autogenous or preserved fascia lata and synthetic products such as nylon or dacron sutures.

A metabolic analysis of high myopia and senile macular degeneration.

Abnormal zinc and copper metabolism have been described in several retinal disorders affecting the retinal pigment epithelium. An infrequent presentation of senile macular degeneration in high myopia is well known. We examined the blood for zinc and copper and the urine for copper of three groups of patients, one consisting of high myopia, another with high myopia and primary retinal detachment and the other a group of patients with senile macular degeneration.

Mitral valve prolapse (Barlow's syndrome) and retinal emboli.

Mitral valve prolapse (M.V.P.

The use of artificial skin in the prevention of early wound healing.

We present our experience in using artificial skin (Omniderm) in the prevention of early healing of a raw lid margin. The material is inert and acts properly for this procedure.

Recurrent tears following successful retinal detachment surgery.

In 17 cases of recurrent retinal tears occurring after successful retinal detachment surgery, the new tears developed on or near the treated primary tear in seven cases and away from the treated tear in ten cases. It took an average of 25.6 months for the second tears to develop, and almost all of the recurrent tears were the same distance from the limbus as the primary tear.

Constant inclined pelvic traction for treatment of low back pain.

The authors describe a technique of continuous pelvic traction applied to a select group of 46 patients with low back pain, who had not responded to at least two weeks of treatment by bed rest and analgesic medication before hospitalization. The traction technique included the use of force equivalent to 25% of body weight, directed at an angle of (15) to the plane of the bed. A mechanical analysis of the technique is described and the results of treatment and the efficacy of the technique discussed.

Copper and zinc metabolism in high myopic patients with retinal detachment evaluation of the Cu/Zn ratio.

In a previous work abnormalities in the copper and zinc metabolism in high myopic patients were found. Primary Retinal Detachment is a common complication of High Myopia. In order to establish further their relationship, a study of the metabolism of these metals was performed in myopic patients with Retinal Detachment.

Branch retinal artery occlusion in patients with Hodgkin's disease.

Ocular involvement in Hodgkin's disease is relatively unusual. This report describes two cases of branch retinal artery occlusion in young patients with Hodgkin's disease. Both patients were thought to be in remission when the occlusions occurred.

Bilateral congenital coloboma of lids, fusion of gums and the temporomandibular joints.

Mandibulofacial dysostosis is a syndrome caused by delay in the development of the first visceral arch. This report describes a case which had fusion of the gums and temporomandibular joint, together with coloboma of both lids. This variant has not previously been reported.

Renal osteodystrophy in end-stage renal failure patients in Israel.

Renal osteodystrophy is one of the major complications in patients on long-term hemodialysis. A group of 42 patients on hemodialysis (mean age 42 yr) were investigated in order to assess the prevalence of renal osteodystrophy in Israeli patients. The patients were examined by X-ray, and 66.

Retinal tears with total vitreous hemorrhage.

In ten cases of nontraumatic retinal tears with initial vitreous hemorrhages so dense that all retinal detail was obscured, medical management included hospitalization, sedation, and binocular patching. It took an average of 4.3 days for the vitreous to clear so that the tears could be examined.

Copper metabolism study in high myopia in the African.

There is considerable evidence which supports a link between abnormalities in copper metabolism and some pigmentary retinopathies. In a previous study, we found such abnormalities in high myopic Caucasian patients. Since the incidence of myopia, and the connection of the latter with retinal detachment, in the black are different from those found in the Caucasian, we modeled the present study on the black after the above-mentioned one carried out on the Caucasian.

Two component femoral head prosthesis-endoprosthesis S-73.

A two component femoral head prosthesis consisting of a metal femoral stem with a small low friction head and HDP cup fitting the acetabulum was used in 80 patients with intra-articular femoral neck fracture; this allowed immediate and relatively painless ambulation and weight bearing. Most of the movement occurs between the stem and cup, so the pain in the joint is eliminated. Except for two cases of technical error there were no signs of instability.
