[Clinical results of the goniothrephining with scleral flap (author's transl)].

During 1971-1976 407 goniotrephinings e.g. "Elliot with scleral flap", were performed at the Univ. Eye Hospital Münster. In a follow-up study of 306 operated cases we found 81% primary glaucoma (62.7% simple glaucoma, 18.3% chronic congestive glaucoma) and 19% secondary glaucoma. In 77% of the operated cases the anterior chamber was restored within the first postoperative day. Gonioscopically in 85% the trephining hole was placed within the trabecular meshwork. Nevertheless, this position of the hole had no decisive influence on the later filtration. Postoperatively 2/3 of cases developed a characteristic flat filtering bleb. In 90.4% of the eyes the postoperative IOP was within normal limits. Postoperative follow-up of the visual acuity remained within the limits of age deterioration. Concerning the secondary glaucoma, the pigmentary glaucoma, the traumatic glaucoma and the glaucoma after uveitis, had good results. The results in cases of buphthalmos and hemorrhagic glaucoma were worse. The advantages of goniotrephining are the rapid restoring of the anterior chamber, the protection of the trephining hole by the scleral flap as well as the well "protected" flat and infections-resisting bleb.

[On the therapy of tractional retinal detachment without hole formation (author's transl)].

The authors describe 6 cases of tractional retinal detachment without hole formation--five as a result of intraocular metal splinter injuries and the sixth after scleral perforation following windshield injury which was overlooked. Splinter extraction was performed twice through the perforation and three times though the pars plana from the ouside. The time between the injury and appearance of the retinal detachment varied between four months and nine years. In every case there was a diffuse falt detachment without obvious tent formation. Reattachment was successful in five cases by release of the traction from the outside by cerclage with folding of the point of traction in the vitreous body and diathermy with drainage of the subretinal effusion. This method described gives relief only when vitreous strands traverse the whole bulbus crosswise. The follow-up period is up to the present three months to a year.

[Misdiagnosis of "chalazion" (author's transl)].

The diagnosis of the often occurring "chalazion" usually puts no problems in diagnostic and therapeutical view. It must be considered, however, that already small particularities of the clinical findings point to other i.e. benign or even malignant processes. An analysis of a number of cases from 1969 to 1975 of the University Eye Clinic Münster showed in 21 out of 89 histologically examined tissue specimen another diagnosis. In 8 patients a malignant degeneration of tissue was histologically stated. The authors describe some cases, where during a longer period of time the malignant character of the disease was not diagnosed due to the misdiagnosed "chalazion".

Tendon-lengthening in squint surgery.

A procedure of tendon-lengthening to correct horizontal deviation of squinting eyes is repopularized. The principle is that the internus rectus muscle is exposed and divided into 3 portions which after suturing will form one elongated portion. Technique, dosage, suturing materials, instrumentation, disadvantages and advantages as well as postoperative care of this method are discussed.

[Misdiagnosis of intraocular iron foreign bodies (author's transl)].

Out of 393 intraocular foreign bodies (1961-1975) 361 were magnetically removed and 32 non-magnetically (copper 7,brass,2,lead 5, glass 10, stone 3, wood 4 and plastic 1).60% of the foreign bodies were caused by hammer and chisel injuries.73 foreign bodies were diagnosed too late, in 71 cases no x-ray was made. The incidence of complications (infection, siderosis, retinal detachment was considerably increased where the foreign bodies were removed late. From the 73 foreign bodies (18.5%) the patient did not consult a doctor in 37 cases because of "insignificance". 4 times the family doctor was consulted, who treated the patient symptomatically. In 4 cases occurring in the weekend no eye-specialist could be ostensibly found. In 26 cases the ophthalmologist performed no x-ray control, and small foreign bodies were twice described as "x-ray plate artefacts" from the roentgen specialist. It must be an absolute rule in the eye-doctor's practice that every injury received while working with metals necessitates an x-ray control!

[Melatonin biosynthesis in the mammalian retina in dependence of light adaptation (author's transl)].

1. The biosynthesis of melatonin was investigated in retinaextracts of bovine eyes in dependence of light adaptation of the animals. S-adenososyl (Methyl-14C) methionin and acetylserotonin were used as substrates. A higher melatonin-biosynthesis was found in the retina from animals which were adapted to lower illumination. 2. The effect of triamterene on the biosynthesis of melatonin in the retina was examined. An increase of melatonin was found in the presence of the diureticum, which is a pteridine compound, when retinas of animals which were kept under low illumination were investigated. The role of melatoninsynthesis in dark adaptation is discussed and it is pointed to a possible danger of blinding in patients which used triamterene. Furthermore it is suggested that triamterene also increases the melatoninsynthesis in the pineal gland and that this may possibly contribute to an understanding of the effect of the diurecticum.

[Correction of Blepharochalasis (author's transl)].

Blepharochalasis implies the symptom or general term (Kettesy) applied to the slackening and thinning out of the upper lid. From a clinical point of view and in a wide sense this includes Cutix laxa senilis or senile epiblepharon. The following surgical procedures restore the lost contract between the skin and the lid elevator. 1. Upper plapebral furrow formation sutures (Kettesy). 2. Blepharochalasis surgery according to the method of Imre. This is a "mild ptosis operation" which is indicated in advanced slackening and dehiszenz of the Fascia tarso orbitalis. 3. The "controlled skin resection" which permits a testing of the function before the skin resection, prevents the excision of muscle fibres as well as too large and irregular skin stripes and provides for a minimum haemorrhage. For this purpose the skin fold near to the upper tarsal margin is lifted up and marked with running sutures along the line of expected upper palpebral furrow. After resection of the lifted lid skin the scarcely bleeding wound is closed with running sutures.

[Temporal arteritis, clinical picture, treatment and prognosis (author's transl)].

32 patients are described, who 1971-1974 were hospitalized because of temporal arteritis. The admissions diagnoses were: 5 temporal arteritis. 7 Neuroretinitis. 4 Blood vessel obstruction. 2 Cerebral tumor. 14 Vision disturbances up to sudden blindness of unknown cause. In the early stages when intermittent visual disturbances with vague headaches of older patients (average age 68 years) are present, a temporal arteritis is often not recognised. In the region of the papilla the retinal arteries show obvious luminal narrowing. The papilla is already early on somewhat blurred and oedematous. The complaints continue bilaterally with intervals from days to months. Hence the treatment: bilateral resection of the temporal artery. Histologically: from our 32 patients 27 showed the classical picture of "giant-cell arteritis" with chronic inflammatory reaction of all layers of the wall and partial to complete obstruction of the vessel lumen. Local therapy: parabulbar application of cortisone. General therapy: Daily rheomacrodes infusions, Soludecortin, 100 mg per day (with latter "tailing off") and strophantin when the patient is not already digitalised.
