Orbital exenteration is a disfiguring procedure performed for unresponsive orbital infections and control of recurrent benign tumours and malignancies arising from the eyelids (basal cell carcinoma, squamous cell carcinoma, conjunctival malignant melanoma), lachrymal glands (adenoid cystic carcinoma) or surrounding sinuses. In extremely rare cases the use of a prosthetic eye after enucleation can lead to anophthalmic socket tumours. We report the case of a 54-year-old man who had left eye enucleation due to recurring events of retinal detachment and who developed an invasive fast growing epidermoid carcinoma 30 years later...

A Holstein calf was born with a large protruding right eye and a central corneal opacity. Enucleation was the first choice of treatment. The calf had a good prognosis and was raised for milking purposes. Macroscopically, the enucleated eye was characterized by the protruded cornea, adherence of the iris to the central posterior cornea and aphakia. Microscopically, central corneal thickening and a defect in the endothelium and Descemet's membrane were observed. These data suggest that this represents a case of unilateral anterior segment dysgenesis consistent with congenital corneal staphyloma with Peters' anomaly and aphakia...

Hospital effluents contain myriad of mutagens and genotoxins capable of increasing DNA damage in aquatic biota. African mudfish, Clarias gariepinus, are exposed to genotoxins when cultured in swamps and derelict water bodies often contaminated by effluents. Moreover, its DNA is susceptible to xenobiotic-induced lesions since it lacks L-gulonolactone oxidase and hence cannot synthesize L-ascorbic acid. This study investigated 96-h acute toxicity and protective effects of dietary ascorbic acid (AA) against micronucleus (MN) and abnormal nuclear (NAs) formation in C...

We report a case of complete dislocation of the globe into the maxillary sinus, with immediate repositioning of the globe. This report highlights the importance of early surgical repair of orbital fracture and globe repositioning to regain the maximum amount of ocular functions. A review of literature found 19 cases of globe dislocation into the maxillary sinus: One case was enucleated 2 months after misdiagnosis as traumatic enucleation, six cases were documented no vision or no light perception, three cases did not have reported vision (patients did not survive), and nine cases with postoperative vision...

We report a rare case with histologically proven melanocytoma of the iris that demonstrated diffuse melanocytic proliferation with uncontrolled secondary glaucoma and investigate the etiology of the intraocular pressure elevation. The patient was a 78-year-old man with a history of darkened iris of his left eye. The intraocular pressure was 39 mm Hg. A slit-lamp examination showed a diffuse darkened iris, and a gonioscopic examination revealed open angle with circumferential heavy pigmentation. There was no pigment dispersion of the anterior chamber and no pigment deposition of the cornea...

INTRODUCTION: Use of Descemet Membrane Endothelial Keratoplasty (DMEK) has been limited because of problems with donor preparation, i.e. tearing of the Descemet membrane and difficulties in unfolding the Endothelium-Descemet-Membrane-Layer (EDML) in the anterior chamber (AC). The purpose of this work was to describe a novel approach to teaching anatomy-based donor and recipient preparation in a DMEK-Wetlab. MATERIAL AND METHODS: We teach successful mono-manual donor preparation of human corneas in organ culture not suitable for transplantation, including peripheral markers for orientation...

Optimal positioning of bone-anchored implants in the treatment of patients with orbital prosthesis is challenging. The definition of implant axis as well as the positioning of the implants is important to prevent failures in prosthetic rehabilitation in these patients. We performed virtual planning of enossal implants at a base of a standard fan beam CT scan using the software CoDiagnostiX™ (DentalWings, Montréal, Canada). By 3D-printing a surgical guide for drilling and implant insertion was manufactured (Med-610™, Stratasys, Rehovot, Israel)...

OBJECTIVES: There is a risk to incidentally spread uterine malignancies, especially sarcoma, if tissue is morcellated during hysterectomy or myoma enucleation. In the last years, a worldwide discussion has been started about this problem. However, the risk seems to be very small in recent studies. This study aims at further investigating the risk of disseminating uterine malignancy during uterine surgery in a tertiary university hospital in Germany. METHODS: In a retrospective setting, all cases of uterine myometrial surgery (hysterectomies and myomectomies) in our clinic during a period of 10 years were identified using clinical databases...
