Introduction: This study aimed to compare the neuroaxonal damage of the optic nerve and retina in multiple sclerosis (MS) patients with and without overactive bladder (OAB).

Patients And Methods: We included patients with MS, divided into two groups, based on the severity of OAB symptoms, as evaluated by the OAB-V8 questionnaire. The groups were compared in terms of each dial of the Expanded Disability Status Scale (EDSS), best-corrected visual acuity, intraocular pressure, peripapillary retinal nerve fiber layer (pRNFL) thickness, macular thickness, and macular ganglion cell-inner plexiform layer (mGCIPL) thickness.

Purpose: To evaluate the efficacy of trephination and monocanalicular/bicanalicular silicone tube use depending on the number of affected canaliculi in patients with canalicular obstruction.

Methods: This retrospective study included 46 eyes of 36 patients who underwent trephination and silicone tube intubation performed by a single experienced oculoplastic surgeon due to canalicular obstruction between 2005 and 2020. Monocanalicular silicone tube was applied to patients with one canalicular obstruction, and bicanalicular silicone tube was applied to those with the upper and lower canalicular involvement of the same eye.

Objectives: To evaluate corneal biomechanics before and after collagen crosslinking (CXL) in patients with progressive keratoconus.

Materials And Methods: In this prospective study, CXL was performed under topical anesthesia after removal of the epithelium (epi-off technique) by applying ultraviolet A (UVA) light at a wavelength of 365 nm and power of 3 mW/cm2 or 5.4 joule/cm2.
