a 65–yrs-old man referred for an ocular discomfort and red eye. the clinical diagnosis was leech in the left eye and its species confirmed as being limnatis nilotica . ocular leech infestation should be considered in patients with a history of swimming or washing their face in streams and lakes. attention should also be given to ocular leech infestation in the differential diagnosis of ocular t...

Cataract is caused due to various factors such as age, trauma, genetics, smoking and substance consumption, and radiation. It is one of the major common ophthalmic diseases worldwide which can potentially affect iris-based biometric systems. India, which hosts the largest biometrics project in the world, has about 8 million people undergoing cataract surgery annually. While existing research sh...

Purpose: To retrospectively estimate the long-term corneal endothelial cell loss in children after perforating corneal trauma and implantation of an iris-fixated anterior-chamber intraocular lens (IOL), either the Artisan aphakia lens or the Artificial Iris Implant, and to compare this corneal endothelial cell loss to that in children who received an Artisan aphakia lens to correct aphakia afte...

Leeches are segmented worms belonging to Phylum Annelida and make up the subclass Hirudinea. Leeches have been historically used in medicine to suck blood from patients. Ocular infestation with leech is rare, moreover it is often misdiagnosed. In this report, we describe 2 patients with continuous bright ocular bleeding after swimming in a pool, and pseudo iris prolapse in a child after trauma ...

PURPOSE To determine the safety and efficacy of the Ophtec model 311 iris reconstruction lens for treatment of visual disturbances, such as glare or photophobia, related to partial or total absence of the human iris. DESIGN Phase I multicenter, nonrandomized, investigational device study. PARTICIPANTS Ten iris reconstruction lenses were placed in 10 subjects at 6 sites. METHODS Iris recon...

PURPOSE Discomfort from light exposure leads to photophobia, glare, and poor vision in patients with congenital or trauma-induced iris damage. Commercial artificial iris lenses are static in nature to provide aesthetics without restoring the natural iris's dynamic response to light. A new photo-responsive artificial iris was therefore developed using a photochromic material with self-adaptive l...

Uveitis-Glaucoma-Hyphaema Syndrome (UGH syndrome, or "Ellingson" Syndrome) is a rare condition caused by the mechanical trauma of an intraocular lens malpositioned over adjacent structures (iris, ciliary body, iridocorneal angle), leading to a spectrum of iris transillumination defects, microhyphaemas and pigmentary dispersion, concomitant with elevated intraocular pressure (IOP). UGH Syndrome ...

Purpose: To investigate the pathogenesis of a secondary iris cyst with an immunohistochemical method. Methods: Single observational case report. A pathologic specimen was obtained from a 5-year-old girl who was found to have a secondary iris cyst. She had a history of previous penetrating ocular trauma and subsequent cataract surgery and pupilloplasty. Immunohistochemical staining with cytokera...

The authors present their experience with the evaluation and follow-up of 62 patients with primary cysts of the iris, discuss their clinical and pathological features, and propose a simple classification for these lesions. The results suggest that the great majority of primary iris cysts, particularly those which arise from the iris pigment epithelial layers, are stationary lesions which rarely...
