Objectives: To evaluate the functional and morphological outcomes of vitrectomy in combination with intravitreal 5% C3F8 tamponade and subretinal injections of tissue plasminogen activator (tPA) and anti-vascular endothelial growth factor (anti-VEGF) in patients with submacular hemorrhage (SMH) and to investigate the preoperative prognostic factors.
Materials And Methods: This retrospective study included 30 patients (16 women, 14 men) diagnosed with SMH secondary to neovascular age-related macular degeneration (AMD). Preoperative SMH thickness and area, ellipsoid zone integrity, and postoperative reduction in the amount of subfoveal blood on optical coherence tomography and fundus photographs were assessed.
Purpose: To evaluate the retinal vascular structure before and after the epiretinal membrane (ERM) surgery by optical coherence tomography angiography (OCTA).
Methods: Twenty-two eyes with ERM (study eyes) had been evaluated by OCTA for superficial capillary plexus (SCP) and deep capillary plexus (DCP) vessel density (VD) at foveal and parafoveal regions and foveal avascular zone (FAZ) before and after ERM removal surgery. Twenty-two fellow eyes were selected as control group.

Background And Objective: To evaluate the acute effects of nicotine on macular microvasculature by optical coherence tomography angiography (OCTA).
Patients And Methods: Non-smokers who were administered 4 mg nicotine gum (study group) or placebo gum (control group) were enrolled, 18 individuals in each group. All participants underwent OCTA at baseline and 1 hour after gum chewing.
Purpose: To compare intraocular lens (IOL) tilt and decentration after Nd:YAG laser posterior capsulotomy in eyes that had femtosecond laser-assisted capsulotomy versus manual capsulorhexis.
Setting: Ekol Eye Hospital, Izmir, Turkey.
Design: Retrospective case series.
Aim: To study the macular structure and vasculature in consecutive nanophthalmic eyes using optical coherence tomography angiography.
Methods: This is a prospective, multicentre, cross-sectional study of patients with nanophthalmos (one or both eyes). The superficial and deep foveal avascular zones (FAZ) were measured both manually and with the machine's built-in automated measurement tool.
