[Implantation of retropupillary intraocular lenses in post-traumatic conditions of the eye].

The investigation comprises the results of post-traumatic artephakias. In the course of 15 months the authors treated 15 patients with traumatic cataract after previous perforating or blunt eye injuries. In 12 patients after extracapsular extraction a retropupillary IOL was implanted. In three patients implantation was not performed. Retropupillary pseudophakia is the optimal correction of aphakia even in patients with previous serious eye injuries. A higher incidence of postoperative complications may be expected.

[Combined use of ultrasound and radiodiagnostic methods in the diagnosis of posterior dislocation of the lens].

In a case record the authors present an account on a patient with an opaque media of the left eye on account of seclusion and occlusion of the pupil. The cause of the unilateral chronic uveitis was elucidated by ultrasonic examination with visualization type A. The cause was a calcified lens dislocated into the vitreous body and fixed to the posterior wall of the eye. The finding was confirmed by a negative X-ray picture and positive finding of a small foreign body with high density on CT. Dislocation of the lens occurred after a blow on the left eye during boxing 15 years before the patient sought medical assistance on account of a painful practically blind eyeball.

[Comparison of the predicted and actual refraction of the eye after intraocular lens implantation].

After previous assessment of the dioptric potency (by means of a SRK formula) the authors implanted the appropriate intraocular lenses. After 4-18 months following implantation the calculated refraction calculated before the intervention was compared with the postoperative reality. In 85% the difference was not greater than +/- 1.5 Dsf. The calculation of aniseiconia was made only in case of preoperative ametropia greater than +/- 2 Dsf.

[Malignant melanoma of the conjunctiva].

The authors analyze six cases with malignant melanoma of the conjunctiva treated at the Ophthalmological Clinic in Brno in 1967-1988. They evaluate contemporary therapeutic possibilities and results of treatment. The prognosis of the condition is in general more favourable than in malignant melanomas of other mucous membranes.

[Delayed extraction of an intraocular foreign body].

The authors describe two cases of siderosis of the bulbus which developed as a consequence of late diagnosis of intraocular foreign bodies. The character of siderosis differed, however, in the two patients. In the first patient the picture of generalized siderosis confirmed also by electroretinographic examination permitted the assumption of an adverse course of the disease already on admission, as was confirmed by the progression of the disease even after removal of the intraocular foreign body. In the second patient probable encapsulation of the foreign body led to focal siderosis and a favourable course of the disease.

[Central serous retinopathy as the first manifestation of malignant melanoma of the choroid].

The authors give an account of 12 patients where the original ophthalmological finding corresponded to central serous retinitis. In the course of check-up examinations the picture changed and finally the complex of applied examinations revealed that a malignant melanoma of the choroid was involved. The authors mention the time needed for the clinical decision on the final diagnosis of the disease which was confirmed histologically after enucleation of the eye. In the conclusion the authors draw attention to the necessity of frequent check-up examinations after the initial establishment of the diagnosis of central serous retinitis with regard to the differential diagnostic possibilities of the above disease.

[Moth fragments as intraocular foreign bodies].

The authors describe an accident leading to penetration of the eye of an 11-year-old boy by an unusual foreign body, and the subsequent diagnosis and treatment. Persistent ocular irritation following a corneal perforation wound, in spite of appropriate treatment, led to the presence of an intraocular foreign body being suspected. The results of radiologic examination, including CT (Siemens Somatom 2), were negative. Only A-scan sonography (Kretztechnik 7002) called attention to the possibility of a foreign body in the vitreous behind the traumatic cataract. Extracapsular extraction was immediately followed by careful removal of very small foreign-body particles from the vitreous. Once the corneal sutures had been removed the irritation decreased. The scanning electron microscope (Cambridge) images of the largest particle showed the foreign bodies to be fragments of a moth (order Noctuideae).
