[The pterygium, Autologous conjunctiva-limbus transplantation as treatment].

Based on a new concept of the limbus as a junctional zone for separating the vascularized conjunctiva from the avascular cornea, this study presents conjunctival/limbal autograft transplantation for 22 cases of pterygium. The pterygia were primary in 17 eyes, cicatricial in 1 and recurrent in 4. In all cases a free transplant of the superotemperal limbus with an adjacent piece of thin conjunctiva was placed in the excision area. Postoperative follow-up ranged from 1 1/2 to 17 months, with a mean of 8.7 months. Only two pterygia recurred. In all other cases ideal anatomic reconstruction was achieved without any side effects. The authors believe that conjunctival/limbal transplantation is an encouraging technique for treating a pterygium surgically.

Conjunctiva

[Value of Doppler carotid artery sonography in ophthalmologic diagnosis].

We report the clinical and Doppler sonographic findings on the internal carotid artery in 230 patients with various purely ocular vascular symptoms. For evaluation, the patients were subdivided into four groups: group I (107): central retinal artery obstruction (CRAO) (13), branch retinal artery obstruction (BRAO) (31), amaurosis fugax (AF) (13), anterior ischemic optic neuropathy (AION) (50); group II: retinal vein occlusion (25); group III: "low-tension glaucoma" (55); group IV: chronic open-angle glaucoma with a possible vascular co-factor (43). In group I with signs of arterial ocular mal-perfusion; 29.5% of cases with CRAO and BRAO revealed significant stenosis or complete obstruction of the ipsilateral internal carotid artery. Only 4 of 50 cases (8.0%) with AION showed positive findings. A remarkable result of this evaluation is the coincidence that nearly all high-grade obliterations and obstructions of the internal carotid arteries diagnosed in this study were exclusively confined to eyes with very severe ischemic changes in both anterior and posterior segments. In no other case was localization or extent of the obstructive process in the internal carotid artery predictive. Venous retinal obstructions with only 16% positive findings did not show any correlation with arterial occlusive disease of extracranial vessels based on demographic aspects and clinicopathological studies. Also no etiological correlation could be detected in either of the glaucoma groups (III and IV).

[Corneal transplantation].

After a brief review of the history of corneal grafting, consideration is given to the topics immunology, and the harvesting and preservation of donor material. The surgical techniques of lamellar and penetrating keratoplasty are briefly discussed. The indications for perforating and lamellar keratoplasty are listed, and the prognosis associated with the individual indications considered. Current problems of corneal grafting are the increasing numbers of operations, the question of the significance of HLA typing, and the evaluation of postoperative immunosuppression with cyclosporine A.

Corneal Diseases

[Initial experience with autologous conjunctiva/limbus transplantation in pterygium].

The present paper reports on the technique and results of conjunctiva/limbus transplantation in 13 eyes with primary or cicatricial pterygium (12 cases and 1 case, respectively). In all cases the pterygia were located nasally. The operation was performed by bare sclera excision, covered with a free graft from the superotemporal conjunctiva and limbus. After a mean follow-up time of 5 months there was only one recurrence. On the basis of a new understanding of limbal diseases the authors believe that conjunctiva/limbus transplantation is an encouraging and appropriate technique for ideal anatomic reconstruction and low recurrence rates in pterygia.

[Surgical iridectomy following acute angle-closure glaucoma. A retrospective study of 107 patients].

In 69 of 107 patients with primary angle-closure glaucoma, it was possible to control intraocular pressure and visual fields by means of peripheral surgical iridectomy; in 17 of these patients topical glaucoma medication was required in addition. In 11 cases a second surgical operation other than iridectomy was necessary: 6 lensectomies for malignant glaucoma in 2 cases and lens subluxation or phacomorphic glaucoma in 4 and 5 filtering procedures. Among the 85 treated fellow eyes 68 were controlled by iridectomy alone and 17 eyes needed additional topical glaucoma medication. One case of persisting wound leakage from the corneo/scleral wound was the only complication observed in this study. The advantages and disadvantages of peripheral surgical iridectomy are compared with those of argon and neodymium: YAG iridotomies. Owing to the low rate of complications the authors apply the surgical approach as the routine technique for primary angleclosure glaucoma.

Follow-Up Studies

[Treatment of the dry eye with vitamin A acid--an impression cytology controlled study].

To test the efficacy of topically applied tretinoin eyedrops (0.01%, twice daily, in a solution of peanut oil) in the treatment of squamous metaplasia of the conjunctival epithelium associated with dry-eye, the authors evaluated the impression cytology (IPC) of a total of 31 patients. The cytological findings were classified into four different stages with an overall range from 0 to 9 points. The average period of treatment was 12 weeks. The patients were classified into three groups: (1) Those with mucin deficiency (Mucin less than - greater than; n = 19), (2) those with Keratoconjunctivitis sicca (KSC; n = 6), and (3) a control group in whom pure peanut oil was used (n = 6). The IPC showed a considerable improvement of squamous metaplasia in the mucin less than - greater than group, by an average of 4.3 points (from 6.2 points before treatment to 1.9 points). No changes were seen in the IPC of the KCS patients or the control group. The results of this study show a good effect of tretinoin eyedrops in patients with a significant decrease in or loss of goblet cells seen in the IPC, a decreased break-up time and with no severe aqueous deficiency of tear film. These patients seem to have a "primary" mucin deficiency induced by the decrease in or loss of goblet cells. There is no indication for tretinoin treatment in patients with aqueous deficiency involving major or accessory lacrimal glands. The results of other previous and recent studies on tretinoin treatment are discussed.

[Bilateral complete cryptophthalmos].

A case of bilateral complete cryptophthalmos combined with other malformations is described. The clinical appearance, histology, and the results of computed tomography and electro-ophthalmological investigations are communicated.

Abnormalities, Multiple

[Surgery on the eye under anticoagulative therapy (author's transl)].

Surgery on the eye of patients on long term anticoagulation therapy is possible. To avoid bleeding suprarenin solution 1:1000, coagulation of conjunctival and scleral blood vessels, incision into the cornea when removing cataracts and iridectomy under the operating microscope are recommended. Local anaesthesia is advisable, has however the risk of a retrobulbar hematoma. Thromboplastin time (Quick) under 15% of the norm should be avoided, and only raised in cooperation with the responsible internist.

Anesthesia, Local

Leiomyoma of the ciliary body.

Clinical, histological, and electron-microscopic study of a leiomyoma of the ciliary body, which was removed by cyclectomy from the right eye of a 55-year-old female patient. This is the second case in the literature in which an excision has been performed and the diagnosis been confirmed by electron microscopy. The differential diagnosis between amelanotic malignant melanoma, schwannoma, and neurofibroma is discussed, and the electron-microscopic characteristics of a leiomyoma are demonstrated.

Ciliary Body

Keratitis from abuse of corneal anaesthetics.

Topically applied anaesthetics are potentially dangerous, as frequent and continuous application may lead to anaesthetic-induced keratitis. Three patients with serious corneal lesions are described.

Cataract operations in a retina centre.

The position of the cataract surgeon in a retinal surgical centre is a particular one. Close collaboration with the retinal specialist obliges him never to lose sight of the judgement of the latter. The retinal surgeon does not judge the success of a cataract operation by the consequent visual acuteness obtained, but must wait to see the fundus of the eye, and in particular the retinal periphery. This is a problem with which we are occupied. We have studied from the point of view of the cataract specialist the modifications and retinal complications occurring in 2000 cataract operations. In addition, we have tried to make, from the point of view of the retina specialist, an analysis of detachments of the aphakia which occurred in relation to the cataract operations during the same period of time.

Cataract

[Cataract operations and glaucoma - a study (author's transl)].

This study reports on the favourable influence of lens extraction alone on intraocular pressure levels in different kinds of glaucoma (wide angle, angleclosure, secondary). Out of 2000 eyes undergoing cataract surgery 162 had medically treated glaucoma prior to surgery. Follow-up examinations of the intraocular pressure could be carried out in 118 eyes over a year. There resulted from this study no certain indications for a combined operation, whose value is discussed.
