Purpose: To determine whether pseudoexfoliation (PEX) syndrome is associated with an increased risk of chronic kidney disease (CKD).

Patients And Methods: In this cross-sectional study, 271 consecutive patients were recruited into 3 study groups---PEX syndrome (n=86), primary open-angle glaucoma (POAG) (n=91), and nonglaucoma controls (n=94)---and underwent serum creatinine testing to determine their glomerular filtration rates (eGFR). Repeat eGFR and testing for urine albumin:creatinine ratio were performed a minimum of 3 months later if the initial eGFR was less than 60 mL/min/1.

Purpose: To evaluate the safety and efficacy of corneal collagen cross-linking (CXL) by riboflavin/UV light for the treatment of keratoconus.

Methods: This randomized, prospective, and comparative study involved 10 eyes with keratoconus diagnosed between September 2006 and January 2008. Each patient underwent CXL in the keratoconus eye.

Objective: To evaluate whether the addition of intracameral lidocaine to topical anaesthesia during cataract surgery leads to a decrease in the administration of intraoperative midazolam and fentanyl.

Design: Retrospective case-control study.

Participants: The eyes of 124 patients undergoing phacoemulsification were included in the study, with 62 in the intracameral group and 62 in the control group.

Purpose: Light- and heavy-chain deposition disease (LHCDD) is a rare form of nonamyloidal monoclonal immunoglobulin deposition disease (MIDD) in which light- and heavy-chain immunoglobulin fragments accumulate systemically, typically leading to end organ dysfunction. Herein we describe the case of a 64-year-old female with a history of Graves' orbitopathy and multiple myeloma who presented with bilateral asymmetric compressive optic neuropathies.

Procedure: A biopsy of the right medial rectus muscle was taken during orbital decompression surgery.

Purpose: To investigate the effect of pretreatment oral and topical diclofenac on pain reduction during panretinal laser photocoagulation (PRP) for proliferative diabetic retinopathy (PDR).

Design: Prospective, randomized, double-masked, placebo-controlled clinical trial.

Participants And Controls: A total of 90 patients with PDR requiring PRP for the first time were assigned randomly to 1 of 3 study groups: oral diclofenac (n = 30), topical diclofenac (n = 31), or placebo (n = 29).

Purpose: To report a case of an abnormally thick flap that was detected with the use of anterior segment optical coherence tomography (OCT) prior to planned LASIK retreatment surgery.

Methods: A 43-year-old man presented 6 years after bilateral LASIK surgery with uncorrected visual acuity (UCVA) of 20/20 in the right eye and 20/100 in the left eye, and best spectacle-corrected visual acuity (BSCVA) of 20/20 in the right eye and 20/20 in the left eye (refraction -2.25 -1.
