BACKGROUND To evaluate the morpho-functional outcomes and safety of transconjuctival 23-gauge pars plana vitrectomy(PPV) for removal of intraocular foreign bodies (IOFBs). METHODS A retrospective study of 36 consecutive cases (mean age; 34,2 ± 10,9 years (between 15 and 60), 27 M,9 F) of 23-G PPV for the removal of IOFBs during the period of April 2009 and December 2011 and followed 9,4 ± 6,4...

PURPOSE Unexplained visual field loss after pars plana vitrectomy (PPV) has been reported in up to 14% of all uncomplicated cases with signs varying from visual field defect and disc pallor, to optic atrophy, loss of vision, and phthisis bulbi. Among the postulated pathogenic mechanism is ocular hypoperfusion due to insufficient blood pressure (NBP) and/or elevated IOP, or to their mismatch. Th...

I N 1998, a 37-year-old woman underwent bilateral same-day laser in situ keratomileusis (LASIK) surgery. The preoperative refraction was −6 diopters (D) for each eye. The surgery on the right eye was uncomplicated. On the left eye, the procedure was complicated by cornealperforation,probablydue tomisassembly of an older-generation microkeratome with a removable spacer plate. Despite surgical re...

PURPOSE To investigate the immediate and long-term outcomes of Ahmed glaucoma valve (AGV) implantation with silicone tube ligation and removable external stents. METHODS This retrospective non-comparative study investigated the outcomes of AGV implantation with silicone tube ligation and removable external stents in 95 eyes (90 patients) with at least 12 months of postoperative follow-up. Qua...

BACKGROUND One of the most challenging problems in vitro-retinal surgery is the recurrence of retinal detachment in the context of high-grade proliferative vitreoretinopathy (PVR). The aim of our retrospective study was to assess the surgical outcomes of pars plana vitrectomy, 180° inferior retinotomy and silicone oil tamponade combined with phacoemulsification and IOL implantation for recurren...

Background Dropped lens fragments into the vitreous are uncommon, but potentially sight threatening complications of cataract surgery. The recommended approach for removal of dropped lens matter is pars plana vitrectomy with or without ultrasonic emulsification with the fragmatome. This study aimed to determine the visual outcome following pars plana vitrectomy for dropped lens fragments compli...

PURPOSE This study was carried out to see the results of glycerol-preserved cornea (GPC) in emergency situation when fresh corneal tissue was not available. The aim was to study the outcome of corneal transplantation using GPC. METHODS This was a retrospective study. The medical records of all the patients were reviewed, who underwent keratoplasty using "GPC" during the period from October 20...

OBJECTIVE To assess the visual outcome and complications after removal of posterior segment retained intraocular foreign bodies through pars plana approach. STUDY DESIGN Case series. PLACE AND DURATION OF STUDY Department of Ophthalmology, Jinnah Postgraduate Medical Centre, Karachi, from May 2005 to May 2006. METHODOLOGY Fifty patients with history of ocular foreign body were admitted th...

Rapid, non-destructive, and accurate quantitative determination of the effective components in traditional Chinese medicine (TCM) is required by industries, planters, and regulators. In this study, near-infrared hyperspectral imaging was applied for determining the peimine and peiminine content in Fritillaria thunbergii bulbi under sulfur fumigation. Spectral data were extracted from the hypers...

The susceptibility of newborn and infant mice to eye infection by Pseudomonas aeruginosa was studied in 5-, 10-, 15- to 16-, and 21-day-old mice. In the first of three age-related susceptibility experiments, inoculation of P. aeruginosa under the unopened eyelids of infant (5- and 10-day-old) mice in the absence of prior corneal wounding resulted in acute infection and rapid death of many of th...
