“…8 Guist's name became attached to these "calcined" bone spheres which were widely used and recommended as "the most satisfactory of all implants" in Spaeth's The Principles and Practice of Ophthalmic Surgery. [9][10][11] After the second world war biologically inert plastic materials displaced the earlier types of implant. Broadly, two types of implant were used, one a monolithic smooth surfaced implant was subject to the complications of late migration and extrusion, while the second type of porous implant, once organised by the tissues, did not tend to migrate but had the disadvan-tage that any exposure of the underlying implant was difficult or impossible to treat without removal of the entire implant.…”

Aims: To document the long term experience of bone derived hydroxyapatite orbital implants and compare results using scleral wrapped implants with those not using sclera. Methods: This retrospective case series reviewed the long term follow up of 118 patients with 120 eyes which had undergone enucleation and bone derived hydroxyapatite orbital implant insertion at Dunedin Hospital from 1977 until 2000. Patient details were obtained from theatre records, case note review, patient interview and examination, interview of patient relatives, and family general practitioner records. Results: Of the 120 eyes 84 had bone derived hydroxyapatite orbital implants with sclera and 36 without sclera. Follow up was 0.5-25 years (mean 8.9 years). 25 (19.3%) suffered minor complications of limited exposure of the implant which resolved spontaneously, with implant drilling or wound resuture. Nine (7.5%) suffered major complications requiring explantation. Major complications were more likely in cases with major tissue disruption, ischaemia, or inflammation. There were significantly fewer complications in the group where a bone derived hydroxyapatite orbital implant was implanted without a scleral covering (p<0.05). Conclusions: The placement of a bone derived hydroxyapatite orbital implant in the socket was associated with a low rate of long term complications and good cosmesis in most cases. The omission of a scleral covering over the hydroxyapatite sphere had some advantages and may prove to be the procedure of choice.

“…Aufgrund der Feststellung von De Wecker [71, die später von Gonin [8,9] aufgegrif fen wurde, dass die Netzhautablösung nur Folge eines Netzhautrisses sein kann, be nutzte Rosengren [10][11][12][13] ab 1938 die in travitreale Luft ausschliesslich als Netzhaut lochtamponade mit erfolgreichen Ergebnis sen. Dieses Rosengren&che Verfahren der intraokularen Lochtamponade mit Luft wur de von Spaeth [14] und Ci bis [15] fortge führt. Später waren es vor allem Schepens und Freeman [16], Clark [17], Norton et al [18], Machemer et al [19] und Kanski [20], die Luft bei der Behandlung von Netz hautriesenrissen mit mehr oder minder gu tem Erfolg einsetzten.…”

After a short historical survey the indication and technique of the intravitreal injection of SF₆-gas within the limits of the actual retinal surgery are discussed and demonstrated by means of 10 cases. The main indications are (1) tamponade of oral and preoral giant tears, (2) tamponade of central retinal foramina, (3) tamponade of equatorial giant holes of 1–2 quadrants as well as tear groups, and (4) SF₆-gas as substitute of the vitreous body.

“…With the initial vitreous loss and the position of the lens we used the loop without attempting to grip the lens with forceps. Spaeth (1948) suggested that the pupil should be fully contracted behind the lens before operation to prevent the lens falling backwards. This again was impossible here because of the position of the lens.…”
