Objective: To evaluate intraocular pressure (IOP) and corneal biomechanical properties changes after intravitreal ranibizumab injection (IVRI).
Methods: One hundred twenty eyes of 120 patients who underwent IVRI between January and March 2018 in Adnan Menderes University Ophthalmology Clinic were included in study. Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg), and corneal-compensated intraocular pressure (IOPcc) were measured by Ocular Response Analyzer (ORA) by the same specialist preoperatively (preop), postoperative 1st (postop-1st), postoperative 3rd (postop-3rd), and postoperative 24th hours (postop-24th) after single-dose IVRI.
Results: Among the 120 wet age-related macular degeneration subjects, 58 (48.3%) were female and 62 (51.7%) were male. The mean age was 64.8 ± 10.4 years. Postop-1st hour IOP cc and IOPg measurements were statistically different from all other measurements (p < 0.001). Postop-1st hour CH measurements were statistically different from preop and postop-3rd (p = 0.022 and p = 0.008, respectively).
Conclusion: After intravitreal injection, IOP pressures significantly increased. But, CH and CRF values were significantly decreased. All these changes were temporary.

Objective: To evaluate the effect of preoperative intravenous mannitol on the capsulorhexis process and intraoperative complications in patients with primary angle-closure glaucoma (PACG).
Methods: In this prospective randomized controlled trial, 65 PACG eyes were randomized into the mannitol and control groups. The capsulorhexis duration, number of forceps grasps, need for viscoelastic re-injection, and intraoperative complications were recorded.

The motion of the trabecular meshwork (TM) facilitates the aqueous drainage from the anterior chamber to the venous system, thereby maintaining normal intraocular pressure. As such, characterizing the TM motion is valuable for assessing the functionality of the aqueous outflow system, as demonstrated by previous phase-sensitive optical coherence tomography (OCT) studies. Current methods typically acquire motion from a single cross-sectional plane along the circumference of the anterior chamber.
