Inverted T Trabeculectomy Primary Congenital Glaucoma

"* Fornix-based conjunctival incision along with the opening of Tenon's capsule and dissection along the area of the potential bleb.~* A 4 x 4 mm limbal-based scleral flap was fashioned using a crescent knife. Dissection was carried out up to the clear cornea.~* A longitudinal tunnel was made through the scleral bed, starting from the limbus and extending 1 mm beyond the end of the scleral flap. Afterwards, the horizontal limb of the Inverted T was created. (Figure 2)~* A paracentesis was made using an MVR blade.~* The anterior chamber was entered using an MVR blade. Kelly's punch was used to excise 1.5 x 1.5 mm of scleral bed at the limbus at the base of the vertical limb of the figure (T), and then a peripheral iridectomy was performed using Vannas scissors.~* The scleral flap was then closed using two fixed 10/0 Nylon sutures, one at each corner."
