Surgical treatment of sympathetic ophthalmia.

We report the case of a 12-year-old girl who was hospitalized for bilateral uveitis that occurred 2 years after a penetrating injury of the left eye. On admission, all clinical signs of sympathetic ophthalmia were present with visual function reduced to light perception and intact projection in the right eye and light perception without intact projection in the left. Ultrasonography confirmed that the retina was in its proper place in both eyes. Since abrasion of the corneal epithelium and decalcification of the cornea with ethylene diamine tetra-acetic acid had been performed on the right eye, it was decided to proceed with pars-plana lensectomy and vitrectomy in the same (better preserved) eye. The surgery was performed as planned, with an uneventful postoperative course. Three years later, the eye operated upon had no signs of inflammation, and the visual acuity achieved with the aphakic correction was 0.8.

[Experimental studies of the tensile strength of laser adhesions]. / Experimentelle Untersuchung über die Anheftungsstärke der Laser-Adhäsionen.

This paper presents results of measurements of laser adhesions in rabbit eyes. A circular area of the retina 2.5 mm in diameter was covered with laser burns (diameter of laser beam 200 microns). The strength of the adhesion was measured on the 8th and 22nd days after coagulation. The adhesive area consisted of 60-65 laser scars. The measuring technique was described by Zauberman and Berman in 1969. The group of 60-65 laser scars produced with a laser beam 200 microns in diameter and distributed over a retinal area 2.5 mm in diameter withstood traction of 90-280 mg after one week and 140-330 mg after three weeks.
