Aim: To prospectively study the success rate and complications of viscocanalostomy, a non-penetrating glaucoma surgery. Methods: Prospective non-randomised consecutive case series of 57 eyes (57 patients) with medically uncontrolled primary and secondary open angle glaucoma. Viscocanalostomy was performed on all participants with injection of viscoelastic in the surgically created ostia of Schl...

Sealing Effect of External Diathermy on Leaking Sclerotomies After Small-Gauge Vitrectomy: A Clinicopathological Report Small-gaugevitrectomyhassurged inpopularity in recentyears and has become a widespread alternative to traditional techniques. Eighty-five percent of retinal surgeons now routinely use 25or 23-gauge systems for uncomplicated macular surgery compared with 22% in 2005.1 These sma...

This paper describes a new technique to suture the radioactive plaque to sclera. The radioactive plaque is conventionally sutured to the sclera using 5/0 nylon sutures. The imbricated suture technique involves using a 1/0 silk or 2/0 mersilene suture imbricated with the 5/0 nylon suture when the nylon suture is tied and cut. The imbricated suture technique allows easy identification of the plaq...

AIMS To study prospectively the success rate and complications of deep sclerectomy with collagen implant (DSCI), a new non-penetrating filtration procedure. METHODS Non-randomised prospective trial involving consecutive patients. 100 eyes of 100 patients with medically uncontrolled primary and secondary open angle glaucoma. A superficial scleral flap was raised and a deep sclerectomy was perf...

PURPOSE To devise a means of providing controlled resistance between the anterior chamber and the subconjunctival space after trabeculectomy by implantation of a biodegradable, porous collagen matrix. METHODS Matrices were implanted in the right eyes of 17 rabbits after trabeculectomy, while left eyes served as surgical controls. The scleral flap was sutured loosely, and the implant provided ...

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 ...

One difficulty with measuring receptive fields in the awake monkey is that even welltrained animals make small eye movements during fixation. These complicate the measurement of receptive fields by blurring out the region where a response is observed, causing underestimates of the ability of individual neurons to signal changes in stimulus position. In simple cells, this blurring may severely d...
