background: uterine rupture at the site of a previous cesarean scar is an uncommon but catastrophic complication of pregnancy, which is associated with significant maternal and fetal morbidity and mortality. case presentation: a 30-year old woman at 24th week of gestation and complaint of pain, contractions and spotting was admitted in royan institute in tehran, iran. she had a past medical his...

OBJECTIVES To evaluate the efficacy of thick acellular human dermis (thick AlloDerm [LifeCell Corporation, The Woodlands, Tex]) grafts for posterior and middle lamellae reconstruction to correct lower eyelid retraction and to compare the long-term efficacy of thick AlloDerm with thin AlloDerm and hard palate grafts. METHODS Retrospective analysis of patients undergoing lower eyelid reconstruc...

Various techniques for scleral fixation of IOL in cases of poor capsular support have been described in past. Sutured scleral fixation of IOLs has been attempted for single piece and toric IOLs also. But this predisposes to various suture releated complications. Sutureless fixation of three piece IOLs with or without glue has gained popularity worldwide. However, odd power lenses and high astig...

OBJECTIVE To evaluate changes in the speed of pupil constriction and in anterior segment parameters after laser peripheral iridotomy (LPI) in patients with angle closure using anterior segment optical coherence tomography. METHODS In this prospective observational study, videos of pupil and anterior segment changes in response to illumination were captured with real-time video recording using...

PURPOSE Scleral stiffening has been proposed as a treatment for glaucoma to protect the lamina cribrosa (LC) from excessive intraocular pressure-induced deformation. Here we experimentally evaluated the effects of moderate stiffening of the peripapillary sclera on the deformation of the LC. METHODS An annular sponge, saturated with 1.25% glutaraldehyde, was applied to the external surface of ...

The morphology of the outflow apparatus in human eyes which had been treated topically with either 2 or 4% pilocarpine on 4 occasions at 6-hourly intervals before enucleation was compared with an untreated control series of eyes from patients in a similar age range. In the pilocarpine-treated group the scleral spur was pulled posteriorly and internally, so that the angle formed by the scleral s...

Bleb revision for hypotony maculopathy following trabeculectomy is an effective technique for raising intraocular pressure and limiting visual loss. The presence for scleral fistula causing over-filtration obviates the need for reinforcing materials, such as donor sclera or pericardium to cover the defect. However, if the surrounding scleral tissue is healthy, a partial thickness scleral flap c...

Treatment options for symptomatic subluxated or dislocated IOLs include observation; and repositioning, removal, or exchange of the IOL. We describe a surgical technique of trans-scleral suture fixation for subluxated bag-IOL complex. A 29 year old male; known case of bilateral recurrent tubercular panuveitis underwent left eye phacoemulsification with three piece hydrophobic acrylic IOL implan...

We describe a technique that uses a capsular hook to obtain sutureless fibrin glue-assisted transscleral fixation of the capsular bag. The hook passes through a sclerotomy created under a scleral flap and engages the capsulorhexis rim, providing scleral fixation intraoperatively and postoperatively. A standard capsular tension ring expands the capsular fornix. The haptic of the hook is tucked i...

The efficacy of scleral grafts for eyelid lengthening in patients with thyroid related upper and/or lower lid retraction was evaluated in 62 consecutive patients with Graves' ophthalmopathy who underwent lid surgery in the last 3.5 years. Seventy-eight upper and 30 lower lids were lengthened by scleral interposition. A good or acceptable result was achieved in 50% of all operated upper lids aft...
