Complications after modern filter operations in glaucoma.

As long as the indications and limitations of laser trabeculoplasty have not yet been established by follow-up over several years, conventional surgical filter operation will not be superfluous. The reduction of the complications brought about by introduction of the scleral flap technique is described. Apart from cicatricial obliteration of the filtering zone, bulbar hypotension due to overfiltration as well as to external fistula and above all the resulting ciliary body-choroid detachment still occurs after trephination with the scleral flap (goniotrephination, trabeculectomy). Attention is drawn to the tension of the scleral flap adapted to the normalized intraocular pressure and reliable preclusion of an external fistula by perfusion test at the end of the operation. The membrane formation probably deriving from the internal Tenon's capsule which leads to a 'pseudofiltering bleb' is discussed as a rare complication (1.5%) which is of basic interest.

[Pulmonary fibrosis following instillation of mitomycin C in the urinary bladder].

Intravesical prophylaxis against recurrence of bladder carcinomas using mitomycin C has proved to be an effective treatment with few side effects. No side effects involving the lungs have so far been observed with systemic administration; with intravesical use, however, this is not the case. We report a 32-year-old man in whom pulmonary interstitial fibrosis occurred after intravesical instillation of mitomycin C. The clinical picture, including the therapy, and the differential diagnosis and practical consequences are all discussed.

[Lung parenchyma disease following instillation of mitomycin C in the bladder].

After instillation of mitomycin C into the urinary bladder severe pulmonary changes developed in a 35-year-old man. This complication has previously been described only after systemic administration of the drug. If mitomycin C is administered locally the lungs should be regularly examined.

[Total lid replacement by an autologous and homologous combination graft in emergencies].

Report on 3 cases with total loss of a lid which required an "emergency lid" in order to protect the cornea. In all cases the tarsus was replaced by a strip of dura mater, the eye-lid skin by a free retroauricular graft. In all 3 cases the attempt was made to mobilize the levator and other adjacent tissue and fix them to the tarsus replacement. In one case the upper palpebral and bulbar conjunctiva was also replaced by 2 flaps of lip mucosa. In this case the lower half of the tarsal zone was rejected; however, the situation was mastered by tarsoconjunctival shifting of the lower lid with a free lid skin graft from the other eye. All "emergency lids" resulted in lid closure which protected the cornea sufficiently. The 2 patients in whom the upper lid was replaced had active lid movement of 3 to 4 mm.

Long-term observations after trephination with scleral flap in glaucoma with threatened point of fixation.

Follow-up examinations 2 months to 9 years after a filtering operation with scleral flap with successful pressure regulation could be carried out in 26 patients with 29 eyes in which a threat to the point of fixation due to glaucoma was present. In the majority of the cases, it was possible to stabilize visual acuity and visual field by the operation. In the remaining cases, there was a slow melting away of the residual visual field without correlation with lens or macular changes or underlying internal conditions.

[Healon as an emergency aid].

Sodium hyaluronate (Healon) was used in follow-up surgery of the anterior segment. In addition to the uses of Healon already documented in the literature the author points out that very early synechiolysis with it can be beneficial especially in cases of distortion of the pupil after cataract extraction with insufficient cleaning of the vitreous. So far Healon has not caused any problems with regard to tissue compatibility, viscosity, resorption or its optical quality in the anterior chamber. The examples of secondary treatment given after injuries are intended to encourage the use of Healon in risky situations as a means of stabilizing the anterior chamber with a viscous fluid.

Replantation of one third of the ciliary body after severe impalement injury.

A massive impalement injury to a 46-year-old man led to corneoscleral laceration, partial aniridia, traumatic cataract and rupture of the orbiculus ciliaris of more than one third of the circumference with extreme hypotony and practically blinding. In addition there was a massive circular haemorrhage into the suprachorioidal space. The course of the operative intervention leading to complete replantation of the ciliary body and so finally to normalisation of the intraocular pressure is described. The gratifying course could have been favoured by the diffuse retrochorioidal haemorrhage.

Bilateral acute vascular retinal necrosis.

In this paper we report on a patient with obliterative retinal vasculitis which, within a few weeks, led to retinal necrosis with fibrous alterations of the central parts of the retina and annular retinal tears in the periphery. The clinical picture is interpreted as bilateral acute retinal necrosis, corresponding to earlier reports in the literature. Our patient differs from the case reports known to us so far in the purely obliterative-vascular progress form of retinal necrosis, the lack of uveal involvement, the presence of unilateral labyrinthine deafness (probably of vascular origin), and the demonstration of pronounced cerebral atrophy.
