AIM To compare the effectiveness and safety of pars plana capsulotomy and vitrectomy using 25-gauge tansconjunctival sutureless vitrectomy system and 20-gauge vitrectomy system for posterior capsule opacification (PCO) in pseudophakic children. METHODS Retrospectively study. Pars plana capsulotomy and vitrectomy using 25-gauge sutureless vitrectomy system was performed for PCO in the study gr...

BACKGROUND Wound healing of the endothelium occurs through cell enlargement and migration. However, the peripheral corneal endothelium may act as a cell resource for the recovery of corneal endothelium in endothelial injury. AIM To investigate the recovery process of corneal endothelial cells (CECs) from corneal endothelial injury. METHODS Three patients with unilateral chemical eye injurie...

We report the case of a 70-year-old female patient who developed corneal edema and iris discoloration following the inadvertent use of 1% methylene blue instead of 0.025% trypan blue to stain the anterior capsule during cataract phacoemulsification surgery. Copious irrigation was performed upon realization of incorrect dye use. Corneal edema and iris discoloration developed during the early pos...

PURPOSE To analize changing trends in indications and surgical techniques of corneal transplantation at an ophthalmological tertiary referral center in Colombia over a 7 year period. METHODS A retrospective analysis was performed of medical records from patients who underwent corneal transplantation surgeries at Fundación Oftalmológica de Santander (FOSCAL) in Bucaramanga, Colombia, between A...

A progressive, apparently inherited corneal dystrophy is described in an inbred line of Manx cats. Initial changes in the cornea are seen at four months of age and characterized by anterior stromal edema. Progressive worsening of the condition produces severe bullous keratopathy with eventual breakdown of both epithelium and stroma. Light microscopic and ultrastructural studies in the advanced ...

AIM To investigate changes in central corneal thickness (CCT) and intraocular pressure (IOP) in children after congenital cataract surgery, as well as risk factors associated with these changes. METHODS 37 eyes of 26 children with congenital cataract undergoing surgery were prospectively recruited. IOP and CCT measurements were performed before the surgery and 6, 12, 18, 24 and 36 months afte...
