The use of split-thickness dermal grafts for successful repair of corneal and scleral defects is reported in 10 patients (11 eyes) who had non-infectious, impending, or overt ocular perforation. In all patients, traditional methods of reconstruction were deemed inappropriate or had already failed. Corneo-scleral defects occurred after various operations: pterygium excision, retinal detachment r...

Purpose. To describe a modified guarded filtration surgery, stab incision glaucoma surgery (SIGS), for primary open angle glaucoma (POAG). Methods. This prospective, interventional case series included patients with POAG (IOP ≥21 mmHg with glaucomatous visual field defects). After sliding superior conjunctiva down over limbus, 2.8 mm bevel-up keratome was used to create conjunctival entry and s...

AIMS Corneal perfusion chambers are important tools in the development and assessment of ophthalmic drugs. The aim of this study was to design and test a modified perfusion chamber suitable for topical application of drugs to isolated corneoscleral preparations, and which allowed continuous monitoring of endothelial cell function. METHODS A polycarbonate and stainless steel perfusion chamber ...

PURPOSE To evaluate the performance of a new system for obtaining corneal lamellar grafts of preset sizes. The system consists of the combination of an artificial anterior chamber (MALKS) and an automated microkeratotome (MASYK). METHODS A prospective study was performed. Lamellar tissue was obtained with the microkeratotome from 40 human corneoscleral buttons mounted in the artificial anteri...

The current study, devoted to leaf micromorphology of tribe Agrimonieae in Iran including three genera (Agrimonia, Aremonia,and Sanguisorba),four species (Agrimonia eupatoria,Aremonia agrimonioides,S. minor, and S. officinalis), and six subspecies (A. eupatoria subsp. eupatoria, A. eupatoria subsp. grandis, A. eupatoria subsp. asiatica, S. minor subsp. minor, S. minor subsp. lasiocarpa, and S. ...

PURPOSE To investigate microbial contamination of the transport medium. Examination of corneoscleral rims is not included in this series. METHODS Transport media of 63 consecutive grafts done at Tennent Institute of Ophthalmology, Glasgow, were collected for microbial examination. RESULTS None of the culture plates showed any growth after prolonged culture, and microscopy was negative in 10...

A 39-year-old Caucasian woman with a history of recurrent conjunctival melanoma of her right eye developed an intrastromal heavily pigmented malignant melanoma, which involved the whole corneal diameter. The patient was treated by corneoscleral lamellar keratoplasty and there has been no evidence of recurrent neoplasm during 4 years of follow-up. This apparently unique presentation of malignant...
