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...

CASE REPORT A 70-year-old male was referred to our department due to a herpetic corneal perforation in the left eye. The perforation was healed with intracameral fibrin tissue sealant (Tissucol(®)), an amniotic membrane, and a large diameter soft contact lens. Postoperatively there were complete dissolution of the fibrin sealant and closure of the perforation without endothelial damage. DISCU...

normal 0 false false false en-us x-none ar-sa background : the aim of this study was to determine the correlation between corneal hysteresis (ch) and the corneal resistance factor (crf), which are both novel methods of analyzing ocular rigidity/elasticity, and various corneal characteristics, mainly corneal volume in normal subjects. methods : this cross-sectional study included 500 normal eyes...

The collagen microstructure of the peripheral cornea is important in stabilizing corneal curvature and refractive status. However, the manner in which the predominantly orthogonal collagen fibrils of the central cornea integrate with the circumferential limbal collagen is unknown. We used microfocus wide-angle x-ray scattering to quantify the relative proportion and orientation of collagen fibr...

PURPOSE To evaluate flap dimensions and cut deterioration with repeated blade use in an automated microkeratome. METHODS The Automated Corneal Shaper (Chiron-Adatomed, Munich, Germany), 160-microm plate attached, was used to make a corneal flap in 90 pig cadaver eyes, reusing blades up to five times. Flap diameter was measured by planimetry and thickness was calculated by ultrasound pachymetr...

PURPOSE To evaluate the effect of transconjunctival lower blepharoplasty with or without a skin pinch on lower eyelid position. METHODS Retrospective analysis of patients undergoing bilateral lower blepharoplasty using a transconjunctival approach with or without a skin pinch. Patients undergoing other surgical procedures that could affect lower eyelid position were excluded. Twenty-five pati...

PURPOSE To compare the repeatability and reproducibility of ocular biometry and intraocular lens (IOL) power obtained with a new optical biometer (AL-Scan) and a standard optical biometer (IOLMaster 500). SETTING Siriraj Hospital, Mahidol University, Bangkok, Thailand. DESIGN Prospective comparative study. METHODS Two independent operators measured eyes with cataract using both biometers....

Purpose: The feasibility of standardized treatment for fungal keratitis was explored through the analysis of results. Methods: The medical records of 508 hospitalized patients with fungal keratitis in Qingdao eye hospital of Shandong province eye institute from January 2008 to December 2012 were analyzed in this retrospective study. Results: Among total 508 cases (all simple eye), 21 cases (4.1...

The axial length of the eye, the radius of the anterior corneal surface, and the diameter of the cornea were measured on 40 eyes of 20 New Zealand White rabbits. The ultrasonographic measurements of the axial length of the eye showed a mean value of 15.12 +/- 0.51 mm (15.33 +/- 0.50 mm in males, 14.96 +/- 0.46 mm in females). The mean corneal radius was 7.26 +/- 0.26 mm (7.18 +/- 0.9 mm in male...

This case report describes the pathological changes found in the markedly clouded and thickened corneal button from a child with bilateral congenital hereditary corneal dystrophy. When surveyed by light and electron microscopy, three types of abnormalities were evident: (1) superficial changes including small subepithelial bullae, interruptions of the thickened epithelial basement membrane, anc...
