[Silicone oil injection in the treatment of complicated retinal detachments].

Silicone oil injection was used in the treatment of 300 selected cases of complicated retinal detachment (after PVR, trauma, giant tears, macular holes, proliferative diabetic retinopathy) and in 7 prephthisical eyes. The anatomical and visual results are analyzed in a retrospective study. Total or partial reattachment was seen in 52% and 27% of the cases reexamined one year postoperatively. At least a navigating visual acuity was achieved in 54%. The results in the different indication groups are discussed. The silicone oil injection was performed after mobilization of the retina by means of pars plana vitrectomy and periretinal surgery.

The intraocular foreign body. Principles and problems in the management of complicated cases by pars plana vitrectomy.

In a retrospective study, the results of pars plana vitrectomy in treatment of injuries with intraocular foreign bodies were described. The patient material was subdivided into five different groups. In 41.6% of the cases, practical blinding could not be prevented. A visual acuity of 0.2 and better was present in 26.6% of the cases. The preoperative (45%) and postoperative (30%) traumatic retinal detachment have an extremely unfavorable prognosis with a reattachment rate of 40 or 21% respectively. The results in the treatment of injuries with magnetic splitters and their sequelae are very much better than those with nonmagnetic foreign bodies. The gunshot and air rifle pellet injuries were the most unfavorable group.

[Silicon plug for retinal surgery (author's transl)].

For some time now a 7.5 mm wide plug made of hard silicon, with a grooved surface to facilitate fixing the thread, has been used in the surgery of retinal foramina to indent the bulbus. The plug has not caused any complications so far.

Pars plana vitrectomy after intraocular foreign bodies.

Pars plana vitrectomy after intraocular foreign body injuries led to a good or at least useful vision in 60% of the cases. Without exception, these were eyes which were practically blind or eyes which according to our experience would have been blinded without vitrectomy. Retinal detachments which have arisen preoperatively have a decisive negative effect on the prognosis: there is a low rate of healing in consequence of traumatic, contusional and metallotic retinal lesions and high MPP rate. Increasing surgical experience, so-called secondary vitrectomy 'in time' as well as improved and more refined vitrectomy instruments lead to better results.

[Indications for pars plana vitrectomy after perforating injuries (author's transl)].

A preliminary report is given on 100 consecutive cases of pars plana vitrectomy after perforating injuries due to nonmagnetic IOFB (9 cases), magnetic IOFB (32 cases) and lacerating injuries (19 cases). Pars plana vitrectomy was performed to remove persistent vitreous membranes, to prevent proliferative transformation with following retinal detachment or to make the IOFB become visible for extraction. These eyes were practically amaurotic but in 43 cases out of 100 a positive results could be achieved (i.e. the retina being attached, posterior pole becoming visible). Indications, technique and complications of both pars plana vitrectomy and FB extraction are discussed. As a result pars plana vitrectomy should be performed within an interval of at least 2 weeks after the first intervention (i.e. wound closure of FB extraction).

[Contribution to the problem of central serous retinal detachment (author's transl)].

We described extensive and multifocal serous detachment of the neuroretina in cases of Harada's disease, optic head pitting, coloboma of choroid and optic nerve-head and bullous retinal detachment (Gass). Peripapillary serous detachment occurred in an additional case after branch occlusion of central retinal artery. Systemic steroids were useful in Harada's disease. The other cases required photocoagulation or argon laser treatment. Bullous retinal detachment did not heal until a buckling procedure was performed. The serous detachment of the neuroretina is considered as an uniform tissue-reaction of choroid, pigmentepithelium and neuroretina. The pathogenesis for this is unknown.
