purpose: to report the histopathological diagnoses of recipient corneal buttons in patients undergoing penetrating keratoplasty. methods: in this observational case series, all recipient corneal specimens sent to the ophthalmic pathology laboratory of the eye bank of iran between 2004 and 2007 underwent histopathologic examination. results: overall, 315 corneal specimens were evaluated. histopa...

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...

The major cause of corneal opacity and resultant visual loss is a critical decrease in corneal endothelial cell density. Due to the fact that corneal endothelial cells do not generally proliferate, cell densities gradually decrease in the corneal endothelium with age. Before we can begin to aid patients with decreasing endothelial cell densities, by inhibiting cell death or stimulating cell pro...

PURPOSE To evaluate the effect of mitomycin-C (MMC) on corneal endothelial cell density (ECD) and morphology after trabeculectomy. METHODS In this prospective comparative case series, 31 eyes with glaucoma underwent trabeculectomy with (group I), or without (group II) MMC. Specular microscopy was performed pre-, and postoperatively at months 1 and 3. Outcome measures included central corneal ...

OBJECTIVE To compare the efficacy and safety of the intraocular lens (IOL)-shell procedure versus conventional phacoemulsification for the surgical treatment of dense cataracts. METHODS Eighty eyes with dense nuclear cataracts were enrolled in a prospective, randomized controlled study. Patients were assigned to two groups. In Group I, the IOL was traditionally implanted after all nuclear fra...

corneal neovasculariuulon (cnj1 can cause significant visual loss. the kinetics of endothelial cells durin{: microvascular growth were studied usinga model of alkaline cauteriuuion-induced neovascularization ofthe 40 rabbits cornea. changes in dna synthetic activity of endothelial cells during neovasculanuuion were assessed by autoradiographic studyojjjl_tdr incorporation, in vivo and in vitro....

PURPOSE To determine changes in the central endothelium and thickness of grafted corneas and the cumulative probability of developing glaucoma, of graft rejection, and of graft failure 15 years after penetrating keratoplasty. DESIGN Longitudinal cohort study of 500 consecutive penetrating keratoplasties by one surgeon. METHODS Regrafted eyes, fellow eyes of bilateral cases, and patients not...

Endothelial cell loss is a key indicator of the quality anterior segment surgery like cataract surgery. The amount and integrity corneal endothelial cells are two most essential factors determining transparency. Aim this study was to compare between superior scleral tunnel incision temporal clear for phacoemulsification. Prospective observational study. This prospective included 50 patients wit...

PURPOSE To compare the outcomes after phacoemulsification performed with the AquaLase and phacoemulsification in MicroFlow system, including surgically induced astigmatism (SIA), corneal endothelial cell damage and postoperative recovery of visual acuity. METHODS The cataracts of Lens Opacities Classification System, version III (LOCS III) nuclear grade below 2 were subjected in this study. N...
