Abstract: Objective To research the applied anatomic characteristics of temporal limbus corneae and provide applied anatomic basis for incision of temporal limbus corneae. Methods The hierarchical structures of limbus corneae of 10 adult cadaveric eyeballs were observed under stereomicroscopy. The width and thickness of the temporal limbus corneae, the distance between main structures of the anterior chamber angle were measured. In addition, the comparison of 40 cases of uncontrolled intraocular pressure cases after the operation of glaucoma was used to prove the therapeutic efficacy of the incisions of temporal limbus corneae. Results By measuring the cadavers, the width of the temporal limbus corneae was (0.62±0.05)mm,the thickness was (0.73±0.04)mm. The distance between anterior border of the Schlemm′s duct and scleral process was (0.44±0.02)mm, the distance between anterior border of the Schlemm′s duct and the Schwalbe′s line was (0.24±0.03)mm. There was no obvious difference of sight between the incision of superior limbus corneae and the incision of temporal limbus corneae. The intraocular pressure of the incision of temporal limbus corneae was lowered than that of the incision of superior limbus corneae (P<0.05). Conclusion The incisions of temporal limbus corneae is applicable for the second operation of glaucoma and complicated cataract.
