The sympathovagal balance of autonomic nervous system in patients with NTG shifted towards sympathetic activity however with no change of 24-h pattern of BPV as compared to controls.

Preservative-free latanoprost has at least the same intraocular pressure-lowering efficacy as benzalkonium chloride-latanoprost, with a better tolerability profile. This may translate into greater control of treatment and improved quality of life.

Both PC and PDS lead to an effective decrease in IOP on a short-term follow-up basis and demonstrate similar efficacy and safety profiles. PDS patients required additional procedures including 5-FU injections, suture lysis, or needling. PC patients required no additional procedures.

Canaloplasty alone or combined with cataract surgery is a successful surgical method of lowering IOP in glaucoma patients. Canaloplasty decreases 24-hour CSLA fluctuation pattern measured with CLS.

We present a surgical technique for evacuating an intracorneal pre-Descemet hematoma that occurred during a canaloplasty procedure. The technique allows both evacuation of the hematoma outside the anterior chamber and preservation of the intact Descemet membrane, and it can be performed within the primary procedure. Intraoperative pre-Descemet hematoma is reported to be a relatively rare complication of canaloplasty; however, to hasten visual recovery and to avoid potentially sight-threatening complications, surgeons should be aware of this possible complication and be prepared to resolve it as early as possible, even within the canaloplasty procedure.
