BACKGROUND/AIM Chemical ocular burn, especially by alkali, may result in damage to the limbal stem cells, fundamental in maintaining the integrity of ocular surface. Clinically, patients manifest abnormal conjunctival-corneal healing with peripheral neovessels, chronic epithelial defect, severe stromal inflammation, and conjunctivalisation of the corneal, which is characteristic of limbal defic...

A 45-year-old male patient presented with necrotizing scleritis after 2 weeks of having undergone ptyregium surgery with bare sclera technique. Examination revealed a scleral thinning measuring 3 x 3 mm with anterior chamber inflammation. Lamellar scleral graft was dissected from the donor sclera and trephined to the approximate size of the scleral melt. Edges of the host scleral melt were fres...

purpose: to evaluate and compare the results of different surgical methods for post-trabeculectomy bleb revision at labbafinejad medical center, tehran-iran, from 1999 to 2003. methods: this study was conducted on all patients who underwent post-trabeculectomy bleb revision due to hypotony [intraocular pressure (iop) less than 6 mmhg] or bleb leakage. surgical methods were: conjunctival advance...

AIM To evaluate the clinical outcome of patients in whom ocular surface reconstruction was performed using amniotic membrane transplantation (AMT) after the excision of large (>20 mm square) ocular surface neoplasias (OSN). METHODS A non-comparative interventional case series. In 16 eyes of 16 patients, excision of large OSN including conjunctival intraepithelial neoplasia (CIN), primary acqu...

We describe a novel surgical technique for pterygium removal taking advantage of the properties of amniotic membrane and limbal epithelial stem cells. A total of 10 eyes underwent pterygium excision with amniotic membrane coverage of the bare sclera and placement of pieces of limbal epithelium in a linear fashion in the affected limbal area covered by a second amniotic membrane using fibrin glu...
