The human corneal surface epithelium is continuously repopulated by the limbal stem cells (LSCs). Limbal Stem Cell Deficiency (LSCD) can lead to corneal opacity and vascularization, with consequent visual impairment or blindness. Many acquired and congenital diseases can lead to LCSD by direct injury to the LSCs, destruction of LSC niche, or both. Based on(More)
PURPOSE To report the midterm outcomes of autologous limbal stem cell transplantation cultivated on amniotic membrane (AM) with or without subsequent penetrating keratoplasty (PKP) in patients with total unilateral limbal stem cell deficiency (LSCD). METHODS Eight eyes of 8 consecutive patients with unilateral total LSCD underwent autologous limbal stem(More)
Limbal epithelial stem cells are the primary source of corneal epithelial cell regeneration. Limbal stem cell deficiency (LSCD) can develop in traumatic, immunologic, or genetic diseases that affect the ocular surface. LSCD leads to conjunctivalization, with corneal vascularization and opacification and subsequent loss of vision. Limbal stem cell(More)
PURPOSE To investigate whether central corneal thickness (CCT), endothelial cell characteristics, and intraocular pressure (IOP) are affected in patients with previous congenital cataract surgery and to focus on their clinical significance. METHODS CCT and IOP measurements and specular microscopy were performed in 31 eyes of 17 cases of extracted(More)
Differentiation between rejection (the most common cause) and many other possibilities for detrimental effects on graft function represents a difficult issue to diagnose the cause of renal allograft dysfunction. This study was designed to determine whether technetium-99m sulfur colloid (TSC) accumulation predicted graft rejection. We prospectively studied(More)
PURPOSE To report the natural history and the outcome after the surgical management of 2 cases of corneal keloids. METHODS Two male patients, 21 and 24 years old, with a history of corneal opacity for 5 and 17 years, respectively, with no history of an ocular trauma were studied. RESULTS The first patient initially underwent a superficial keratectomy(More)
BACKGROUND/AIMS Retinoblastoma is a highly malignant eye tumour in children with different survival rates across the world. The aims of this study are to determine the globe and patient survival in children with retinoblastoma in a major referral centre in Iran. METHODS 156 eyes of 105 consecutive patients with retinoblastoma were enrolled from 2001 to(More)
A randomized, double-blind, placebo-controlled clinical trial was conducted among 44 subjects to assess the efficacy of EMLA cream application without occlusive dressing on pain on needling (PN) and pain on injection (PI) felt during multiple botulinum toxin type A (BTA) injections for correction of hyperkinetic upper facial lines. Mean PN score was less(More)
PURPOSE To report the clinical features and surgical management of aniridic fibrosis syndrome using the type I Boston Keratoprosthesis (KPro). DESIGN Interventional case series. METHODS Retrospective chart review of 9 eyes in 9 patients with congenital aniridia that developed aniridic fibrosis syndrome. RESULTS All patients had clinical diagnosis of(More)
To evaluate the role of cryotherapy of sclerotomy sites in prevention of late (after 4 weeks) post-vitrectomy diabetic hemorrhage. In a prospective randomized double-masked clinical trial, a total of 124 eyes of 119 patients underwent pars plana vitrectomy for complications of proliferative diabetic retinopathy. At the end of vitrectomy, the eyes were(More)
