摘要:

In a case of keratotorus on both sides with extreme thinning of the cornea first a lamellar and in a second sitting a perforating keratoplasty was performed. Surgical approach and postoperative results are discussed.

摘要:

A description is given of a case of Stevens-Johnson syndrome clinically and histologically ascertained in a middle-aged male with typical localization and later chronicity of the ocular involvement. Besides, an outline is drawn of its clinical picture and of the etiopathogenetical hypothesis, dwelling upon the allergic hypothesis though not excluding the iatrogenic one.

摘要:

In 600 patients with successfully operated unilateral retinal detachment, the visual acuity prognosis of the operated eye was studied in relation to that of the normal eye. Within 2 years after operation, most of these patients were in the following three groups: (1) visual acuity worse than 0.5 in the non-detached retina and worse than 0.1 in the reattached one; (2) visual acuity better than 1.0 in the non-detached retina and worse than 0.3 in the reattached one; and (3) visual acuity better than 1.0 in the non-detached retina and better than 0.8 in the reattached one. Some of the patients in group 2 showed greater improvement of the visual acuity in the reattached retina, which occasionally became superior to that in the non-detached one. In spite of possible improvement until 2 years after operation, the visual acuity in the reattached retina was apt to decrease after more than 5 years following operation. The presence of macular detachment was ill for the recovery of visual acuity. About 30% of the patients with a visual acuity of about 1.0 in the non-detached retina showed no improvement of the visual acuity in the reattached retina. About 50% of the patients with successful surgery for retinal detachment had a difference of more than 0.6 in visual acuity between the non-detached and the detached retinas.

摘要:

The presentation deals with operative difficulties during vitreous surgery for the removal of long-retained intraocular foreign bodies (IOFBs). The cases described and the problems discussed are: (1) IOFBs embedded deeply in dense fibrous tissue which cannot be exposed and removed, (2) IOFBs located in a ‘dead space’ at the anterior pars plana and ciliary body regions, (3) readherence of a residual stump causing traction retinal detachment, and (4) abnormal hyperviscosity of the vitreous in perforation injuries with long-standing retained IOFBs, without vitreous hemorrhage. The presentation shows that an envelope of dense fibrous tissue does not prevent the spread of metallic ions. It emphasizes that an early surgery, before fibrous organization develops, is imperative.

摘要:

22 patients with extending intraocular lesions are examined by serial computed tomography after a bolus injection of contrast medium. The changes of X-ray density of the tumor areas are compared with those of the vitreum and of brain tissue. Choroidal melanomas exceeding 2 mm in prominence are identified as highly vascularized areas in which contrast enhancement according to certain brain tumors takes place. A differentiation from large pseudotumors seems to be possible. The value of this method for the differential diagnosis of choroidal melanomas is discussed.

摘要:

The influence of stimulus size in computer perimetry of central visual field defects was investigated in 30 glaucomatous eyes of 30 patients. 12 eyes had been studied utilizing stimulus size 1 and 3, 18 eyes with stimulus size 3 and 5 at the computer perimeter Octopus (program 31). Using large test targets small scotomata can be overlooked and identified field defects appear smaller and less deep. To evaluate this well-known phenomenon quantitatively by computerized perimetry was the aim of the present study. The mean threshold values in the diseased areas of the glaucomatous fields were about 6–10 db higher with stimulus size 3 than 1 and again 6–10 dB higher with stimulus 5 in comparison to 3. The clinical significance of these findings is discussed for different types of perime

摘要:

The Kodak TP 2415 is a panchromatic film which at the exposure index of ASA 200 combines a high resolving power (320 lines/mm) with an extremely fine granularity (RMS 8). It can be processed within 150 s by a modified Kodak Prostar I-L processing machine. These properties make this film very suitable to be used in clinical fluorescence angiography.
