AIM To determine the difference of surgical induced astigmatism between conventional 20-gauge sutured vitrectomy and 23-gauge transconjunctival sutureless vitrectomy, and the influence of corneal pachymetry and intraocular pressure (IOP) on surgical induced astigmatism in diabetic patients. METHODS This retrospective, consecutive case series consisted of 40 eyes of 38 diabetic subjects who un...

PURPOSE The purpose of this study was to report a novel model for comparing mechanical resistance to intraocular pressure (IOP) increases with 23-gauge (23G) and 25G transconjunctival sutureless vitrectomy (TSV) sclerotomies in the immediate postoperative period using an experimental model of a vitrectomized eye. METHODS This was a prospective, experimental, randomized, and observer-masked ex...

BACKGROUND Transconjunctival Sutureless Vitrectomy (TSV) is a recent advancement in vitreo-retinal surgical techniques involving the use of 25 G instruments through self-sealing sclerotomies. It has been hypothesized that there may be less chance of vitreous and retinal herniation in the scleral wound as compared to conventional sclerotomy incision. However there are no reports on differences i...

Dear Editor, Cho et al. [1] described the “Sutureless intrascleral pocket technique of transscleral fixation of intraocular lens in previous vitrectomized eyes’’ in April issue. The authors prepare two scleral pockets with a crescent knife 2 mm from the limbus and opposed 180 degree each other without any conjunctival dissection. Following, they enter into the posterior chamber with a 26-gauge ...

Decompression retinopathy is a rare postoperative complication of eyes that undergo sudden ocular decompression. It has been reported mainly after glaucoma filtering surgery. The clinical appearance is characterized by multiple round intraretinal hemorrhages, some with white centers, located in the postequatorial retina. Twenty-five–gauge transconjunctival sutureless vitrectomy (TSV25) has rece...

Purpose. To present initial experience with a novel biopsy method, the Essen biopsy forceps. Therefore, two patients with diagnostic suspicion of uveal melanoma underwent biopsy for histopathological confirmation. Case Presentation. Two patients presented with painless unilateral vision reduction. Ultrasound revealed the diagnostic suspicion of uveal melanoma. Therefore, biopsy with the Essen b...
