[Long-term results of autologous conjunctiva-limbus transplantation in pterygium].

Background: Conjunctiva-limbus autografting is known as a safe surgical technique for the removal of pterygia, with a low rate of recurrence. However, the long-term effect of this surgical maneuver is not clear. This study now investigates the long-term efficacy of conjunctiva-limbus autografts to prevent pterygium recurrence.

[Pterygium excision with intra-operative administration of low dosage mitomycin C].

Pterygium excision with postoperative instillation of mitoymcin C (MMC, 0.4 mg/ml) is encouraging because of the technical simplicity and low recurrence rates, but serious postoperative complications have been described (scleral necrosis, corneal perforation, glaucoma, cataract). The authors studied the efficacy and safety of pterygium excisions with a single intraoperative application of low-dose MMC (0.

[Diagnosis and and differentiation of dry eye disorders].

Artificial tears often fail in dry eye patients. Our goal was to establish a diagnostic approach that involves alternatives that are more effective for the treatment. We examined 110 patients with dry eyes not stabilized by artificial tears: medical history, visual acuity, slit lamp examination, rose bengal stains and fluorescein stains, Schirmer test, break-up time (BUT), dye tests, impression cytology, and lid transillumination.

[Therapy of dry eye disorders].

Background: The treatment of dry eyes with artificial tears often fails. We differentiated the disturbances of the three layers of the tear film in 90 such patients. This showed that only 11.

[Ocular complications of long-term survival of bone marrow transplantation. A prospective study with 21 patients].

Background: Survival time after bone marrow transplantation is getting increasingly longer and secondary ocular complications need to be identified and deserve more attention as so far.

Patients And Methods: We evaluated the ocular complications of 21 not selected, long-term survivors after bone marrow transplantation in a prospective study. The ophthalmological examination consisted of visual acuity, slit lamp examination, tonometry and ophthalmoscopy.

[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.

[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.

[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.

[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.

[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.

[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.

[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.

Visual hallucinations in ophthalmology.

Forty-three patients with severe visual impairment due to bilateral eye disease were assessed for visual hallucinations, 28 of them after eye surgery. Ages ranged between 65 and 93 years and none of the patients had any psychiatric disorder. Five of the 43 patients were diagnosed as cases with Charles Bonnet syndrome reporting visual hallucinations that had developed in the course of sight deterioration.

[Therapy of acute keratoconus].

The incidence of acute keratoconus has increased in recent years. A defect of the endothelium and Descemet's membrane allows the aqueous to flow into the stroma. The therapy of choice is penetrating keratoplasty.

Ultrastructure of the rabbit corneal stroma after experimental keratomileusis.

Experimental keratomileusis operations were performed on 13 rabbit eyes. The corneas of the rabbits, in particular the stroma, were investigated up to 24 months after the operation by light and electron microscopy. The most striking features of the corneal ultrastructure following experimental keratomileusis were the presence of abnormal collagen fibrils and electron-translucent vacuoles in the interface.
