[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.

[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.

[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.

[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.

[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.
