purpose: to evaluate the effect of aamniotic mmembrane ttransplantation (amt) in the management of acute severe ocular chemical burns. methods: this randomized clinical trial was performed in eligible patients with grade iii & iv acute chemical burn who randomly received conventional medical therapy (15 eyes) versus combined medical & amniotic membrane transplantation (15 eyes). main outcome me...

The aim of this study was to detect a spectrum of cytokeratins (CK) present in the adult human cornea, limbus and perilimbal conjunctiva. Cryosections from seven corneo-scleral discs were fixed, and indirect immunofluorescent staining was performed using antibodies directed against CK1-CK10 and CK13-CK20. The percentage of positive cells was calculated in the epithelium of the cornea, limbus an...

PURPOSE To visualize and quantify conventional outflow directly in its anatomic location. METHODS We obtained fluorescein canalograms in six porcine whole eyes and six porcine anterior segment cultures. Eyes were perfused with a constant pressure of 15 mmHg using media containing 0.017 mg/ml fluorescein. Flow patterns were visualized using a stereo dissecting microscope equipped for fluoresce...

PURPOSE To report a case of conjunctival microangiopathy secondary to diabetes presenting as a red eye 5 years after glaucoma implant surgery for neovascular glaucoma. MATERIALS AND METHODS A 52-year-old Tongan male with a past history of neovascular glaucoma secondary to proliferative diabetic retinopathy underwent slitlamp examination and color photography of the anterior and posterior segm...

purpose: to evaluate stem cell deficiency using impression cytology (ic) in patients with chronic and delayed-onset mustard gas keratopathy (mgk). methods: a consecutive series of patients with mgk underwent ic. thirty-five eyes of 18 patients (all male) with mustard gas keratopathy were included in this observational case series. presence of goblet cells on the corneal side of specimens was co...

PURPOSE To quantify regional changes of conventional outflow caused by ab interno trabeculectomy (AIT). METHODS Gonioscopic, plasma-mediated AIT was established in enucleated pig eyes. We developed a program to automatically quantify outflow changes (R, package eye-canalogram, github.com) using a fluorescent tracer reperfusion technique. Trabecular meshwork (TM) ablation was demonstrated with...

BACKGROUND To develop a new diagnostic technique to determine vertical ocular deviations when the center of the pupil is covered by swollen eyelids in up- and downgaze. PATIENTS AND METHODS In upgaze (downgaze) the reflex of a diagnostic lamp held at about 50 cm distance from the patient is observed on the lower (upper) limbus. In the case of an asymmetric reflex, prisms are used to obtain sy...
