Risk factors of non-arteritic anterior ischaemic optic neuropathy and central retinal artery occlusion.

Aim: To investigate the difference in risk factors between non-arteritic anterior ischaemic optic neuropathy (NAION) and central retinal artery occlusion (CRAO) and develop a predictive diagnostic nomogram.

Methods: The study included 37 patients with monocular NAION, 20 with monocular CRAO, and 24 with hypertension. Gender, age, and systemic diseases were recorded.

Risk factors for persistent epiphora following successful canalicular laceration repair.

Aim: To identify the risk factors of epiphora in patients with anatomical patency after surgical repair of canalicular laceration.

Methods: This retrospective case series included 178 cases of canalicular laceration repair from 2005 to 2012. Demographic data collected from each patient included age, sex, type of injury, distance from the distal lacerated end of the canaliculus to the punctum, the severity score for the structural abnormity of the medial canthus, the duration of stent placement, and the timing of surgery.
