Ophthamology

Cysts of 2 isolates of Acanthamoeba from the cornea of 2 patients with confirmed Acanthamoeba keratitis were tested in vitro for sensitivity to antimycotic agents such as fluconazole, miconazole, amphotericin-B, pimaricin, antiprotozoal agents such as pentamidine isetionate and antiseptics which could be use in the ophthamological region. Pimaricin was the most successful cysticidal agent against the two strains. Sensitivity to pentamidine isetionate showed variation. Fluconazole, miconazole and amphotericin-B were resistant against cysts with concentration of eye drops that have been used in the treatment of Acanthamoeba keratitis...

Two first cousins both suffering from insulin dependent diabetes mellitus since early childhood developed progressive optic atrophy from the age of 5 and 9 years respectively. They had similar ophthamological features which include optic atrophy with cupping, paracentral scotomata, and total achromatopsia. One patient also had stunted growth, delayed puberty and psychiatric disorder. Neither had diabetes insipidus and deafness. It is suggested that they may be a variant of DIDMOAD (Diabetes Insipidus, Juvenile Diabetes Mellitus, Optic Atrophy, Deafness)...

With preferential looking (PL) techniques, especially the Acuity Card Procedure (Teller Acuity Cards), the visual acuity in small children can be determined. PL-testing was used in 294 children in the Strabismus and Amblyopia Department of the Ophthamology Hospital in Kraków. These children had been directed from other ophthalmologic departments. Almost all of them showed general retardation and their visual acuity could not be tested with traditional methods. The testing was considered positive when the visual acuity of each eye could be determined separately...

Encephalocraniocutaneous lipomatosis (ECCL) is a congenital hamartomatous disorder characterised by unilateral skin lesions, lipomas, and ipsilateral ophthamological and cerebral malformations. The disorder is thought to represent a localised form of Proteus syndrome. In this report, a child is described with ECCL and a de novo nonsense mutation in exon 29 (S1745X) of the neurofibromatosis type 1 (NF1) gene. Although it is possible that both ECCL and NF1 occur coincidentally in this patient, we favour the hypothesis that in exceptional cases a mutation in the NF1 gene might give rise to severe congenital malformations such as ECCL...

BACKGROUND: Iridocyclitis has been identified as a dosage-dependent side effect in patients with the acquired immunodeficiency syndrome who are treated for Mycobacterium avium complex infections with systemic Rifabutin. We reviewed cases of acute hypopyon uveitis occurring in patients with AIDS to establish whether there was an association or not. METHODS: All patients were referred by an infection disease specialty service for complete ophthamological evaluation and ancillary laboratory...

The effect of man-made mineral fibers on the human eye was investigated in a cross-sectional study of 15 workers exposed to Rockwool and a matched reference group of 15 people. Eye symptoms, changes in the cellular and mucous content of the conjunctival fluid, break-up time of the precorneal film, the number of microepithelial defects, and the number of dead and degenerated cells on the cornea and bulbar conjunctiva were used as measures of effect. The number of fibers accumulated in the eye and conventional dust sampling methods were used as measures of dose...

In the present epidemiologic study 80 car or industrial spray painters with long-term low level exposure to organic solvents were examined and compared with two matched reference groups of nonexposed industrial workers (80 persons in each group). The aim of the study was to investigate the possible effects of the solvent exposure on health. The investigation included psychiatric interviews, psychometric tests, neurological, neurophysiological and ophthalmologic examinations, and computed tomography of the brain...

Three generations of a kindred had a history and physical findings consistent with congenital contractural arachnodactyly (CCA) segregating in an autosomal-dominant manner. Six of the seven affected patients we examined had mitral valve prolapse (MVP) diagnosed clinically or by echocardiography. The family members without CCA did not have MVP. This association of cardiac involvement with CCA further lessens the distinction between CCA and the Marfan syndrome. The indication for ophthamologic and echocardiographic follow-up of patients carrying the diagnosis of CCA is stressed...

Nonspecific aortoarteritis is a systemic autoimmune disease eventuating in gradual stenosis of the aorta and the main vessels with ischemia of the respective organs. Ophthalmologic symptoms have been examined in 54 patients with nonspecific aortoarteritis. Subjective disorders of vision (short-term binocular blindness, metamorphopsia, pain behind the eye, amaurosis fugax) have been detected in 52% of the examinees. Organic lesions of the eye have been diagnosed in 60% of the patients: hypertensive angiopathy (22%), venous stasis retinopathy (17%), occlusion of the central retinal artery (1%), etc...

We have reviewed the charts of 45 neuro-ophthamological patients diagnosed with 79 monocular visual field or visual acuity losses secondary to non-organic etiology. Our aim was to determine the percentage of patients that have improvement in vision. As part of the protocol, all patients had magnetic resonance images, pattern visual evoked potentials, and flash electroretinography in addition to complete neuro-ophthalmological examinations. A single physician performed both the initial and follow-up examinations of all patients...

Drug usage review and inventory analysis data on the cephalosporin antibotics were presented by the pharmacy to a hospital pharmacy and therapeutics committee in an effort to promote rational use of these drugs and decrease drug costs. The committee recommended that cefazolin be the parenteral cephalosporin of choice. Cephalothin was placed on a limited formulary status for ophthamology patients and patients with renal impairment. Efforts by the committee to promote physician compliance with its recommendations are discussed...

The author describes first of all the history of photocoagulation from its very beginning up to the most recent instruments. Then examples are given of the different possibilities of application. Besides the detachment of the retina and the tumors, the diseases of the vessels of the retina are playing an important role.
