Randomized Controlled Trial Comparative Study Clinical Trial
Lidocaine 2% gel versus lidocaine 4% unpreserved drops for topical anesthesia in cataract surgery: a randomized controlled trial.
To compare intracameral levels and clinical efficacy of lidocaine 2% gel with lidocaine 4% unpreserved drops. ⋯ If administered by means of gel, the same amount of lidocaine gives significantly higher intracameral levels of lidocaine, better analgesia, better patient cooperation, and less need for intraoperative supplemental anesthesia. Lower pain scores do not correlate with intracameral lidocaine levels.

Randomized Controlled Trial Comparative Study Clinical Trial
Changes in intraocular pressure and ocular perfusion pressure after latanoprost 0.005% or brimonidine tartrate 0.2% in normal-tension glaucoma patients.
To evaluate and compare the effects of latanoprost 0.005% once daily and brimonidine tartrate 0.2% twice daily in patients with normal-tension glaucoma (NTG). ⋯ Both latanoprost and brimonidine reduce IOP in NTG patients. Brimonidine has a peak IOP-lowering effect equal to that of latanoprost but produces a higher mean diurnal IOP than does latanoprost because of its shorter effect. Latanoprost might favorably alter optic disc blood perfusion by increasing OPP.

Randomized Controlled Trial Comparative Study Clinical Trial
Argon laser peripheral iridoplasty versus conventional systemic medical therapy in treatment of acute primary angle-closure glaucoma : a prospective, randomized, controlled trial.
To study whether argon laser peripheral iridoplasty (ALPI) is as effective and safe as conventional systemic medications in treatment of acute primary angle-closure glaucoma (PACG) when immediate laser peripheral iridotomy is neither possible nor safe. ⋯ Argon laser peripheral iridoplasty significantly is more effective than conventional systemic medications in reducing IOP levels in acute PACG in eyes not suitable for immediate laser peripheral iridotomy within the first 2 hours from the initiation of treatment. Argon laser peripheral iridoplasty is a safe and more effective alternative to conventional systemic medications in the management of acute PACG not amenable to immediate laser peripheral iridotomy.

To identify and characterize the loss of stereopsis observed in patients with lesions of the optic chiasm. ⋯ The difficulty with stereopsis in patients with lesions of the optic chiasm is most likely caused by the compression of the decussating optic nerve fibers resulting in the loss of an overlapping visual field at the fixation point. Stereo tests were demonstrated to be simple and effective adjunctive tests for suspected chiasmal compression.

This study was performed to evaluate the clinical course of patients treated for traumatic microhyphema and the occurrence of elevated intraocular pressure (IOP) and secondary hemorrhage in these patients. ⋯ Complications from traumatic microhyphema treated with standard measures are few. Closeness of follow-up may be determined by IOP on presentation. Secondary hemorrhage seems to be unaffected by the use of topical corticosteroids.
