Effectiveness of low-volume split-dose versus same-day morning polyethylene glycol regimen for adequacy of bowel preparation in patients undergoing colonoscopy: A single-blinded randomized controlled trial.

Background: Successful completion of colonoscopy depends largely on the quality of bowel preparation. Polyethylene glycol (PEG) is a commonly used preparation for colonoscopy. The timing of bowel preparation has evolved from previous day evening to the currently recommended split-dose regimen.

Anatomical and functional features of photic retinopathy: a spectral domain optical coherence tomography-based longitudinal study.

Background: Photic retinopathy may lead to permanent foveal structural injury, leading to irreversible visual acuity loss.

Method: This prospective observational study evaluated 51 eyes of 30 patients with photic retinopathy. Optical coherence tomography (OCT) imaging was performed for all the eyes at baseline and final follow-up.
