A contribution to the history of spectacles in Croatia.

The earliest data on spectacles in Croatia originate from the 14th century. Inventories of personal belongings and valuables of distinguished individuals testify about the existence of spectacles from the 14th century onward. Pictorial representations of spectacles and spectacle cases are found in Croatia in various forms: as a watermark in a 14th century paper, on a silver altar-piece from 1477, on paintings, frescoes and wood-cuts from the 15th century onward. A pair of 16th century spectacles are kept in Split (Poljud) and a selection of 18th to 20th century spectacles are on display in various museums in Croatia. In 17th century literature the effect of lenses on ametropia is discussed and Latin and Croatian terms for spectacles and opticians are mentioned.

[Morphology of nystagmus in childhood].

Taking 100 patients with nystagmus--aged between 4 and 12--seen by the authors, the numerous different waveforms and wave types were classified on the basis of the electronystagmograms. The most common forms of nystagmus were the pseudopendular, the pseudocycloid, and the pendular. Over 25 percent of the nystagmograms were cases of latent nystagmus and were therefore excluded from the waveform analysis. The average visual acuities for the various nystagmus waveforms are compared.

[Diagnosis and treatment of Stilling-Türk-Duane syndrome (clinical electromyographic and electrooculographic studies)].

The results of clinical, EMG and EOG examinations in 42 patients with Duane's syndrome are analyzed and some characteristic clinical examples are presented. The clinical analysis of motoric and sensoric disturbances in Duane's syndrome reveals elements of concomitant squint in ocular statics. Dynamically, there are marked differences with regard to concomitant and paralytic squint. A number of interesting observations are reported relating to the permanent tonic innervation of the lateral rectus muscle, polymorphic EOG dyssynergia in saccadic and smooth pursuit movements and the progression of the clinical picture in some patients with Duane's syndrome. Twenty patients were surgically treated with relatively good results or at least some improvement.

[Electronystagmographic evaluation of surgical results in nystagmus treatment].

In the management of congenital, ocular nystagmus as well surgical procedures (according Kestenbaum, Anderson and similar modifications) with the purpose of shifting nystagmus "neutral zone" in the primary position of gaze, as nonsurgical treatment with prisms, show favourable effect on head position, nystagmus intensity and visual acuity. In this preliminary report the authors tried to evaluate, by means of electronystagmography, their clinical experiences in some treated nystagmus cases, objectively. The electronystagmographic findings of nystagmus amplitude, frequency and intensity, depending on position of gaze, were before and after surgery, respectively treatment analysed.

[Echographic patterns of orbital cholesteatomas and fibromyxomas].

UNLABELLED: Orbital cholesteatomas and fibromyxomas are relatively rare, but in echographic tissue differentiation both should be taken into consideration to avoid misdiagnosis. An orbital cholesteatoma may be mistaken for a hemangioma or a mixed tumor. Orbital cholesteatomas are distinguished by the following characteristics; high reflectivity, usually typical subperiostal location, wall or bone spikes, incompressibilty and immobility. Fibromyxomas are recognizable by their relatively regular structure, low to medium reflectivity and marked vascularity; they are poorly outlined, often showing signs of cellulitis. DIFFERENTIAL DIAGNOSIS: "periorbital malignancy" and the acoustic diagnostic group "sarcoma-lymphoma-pseudotumor".

[Chronic progressive external ophthalmoplegia with atypical retinal pigment dystrophy (author's transl)].

A brief review of the literature on chronic progressive external ophthalmoplegia is followed by a description of two unusual cases. The first, Kearns-Shy syndrome, was a pronounced case of "ophthalmoplegia-plus syndrome", though with normal retinal function. The second patient had retinal pigment dystrophy with severe disturbance of retinal function, as well as a complete lack of ocular motility.

[Ophthalmological themes in baroqueiconography in north-west Croatia (author's transl)].

The northwest Croatia is distinguished through valuable master-pieces of exuberant baroque art. Cultural comprehensions and spirit of time are registered in numerous sacred and profane monuments of art. It is also understandable, that actualities of medicine are reflected in art, too. Small and big plastic-arts, pictures and frescoes are iconographic material of what ophthalmological themes we try to analyse to conceive knowledges about health and sick eyes in that time, about regional pathology and social aspects of eye diseases, also thus to get to learn ophthalmological problems of that time.

[Electrooculographic examination in paralytic and concomitant squint (author's transl)].

There are shown some possibilities of electrooculographic diagnostics in different forms of strabismus. Kinetic disturbances in fusion in concomitant squint are usually frequent but not constant and in the majority they are different from incomitances in paralytic squint. In this mind electrooculography represents subtile and perspective method in examination of ocular motility.
