Article Synopsis
  • The study aimed to assess the impact of the first dose of the Sinovac vaccine on various eye structures in healthy individuals, comparing vaccinated participants to unvaccinated controls.
  • Conducted with 27 healthcare workers who received the vaccine and 25 controls, ophthalmological assessments were done before vaccination and at one week and one month after.
  • Results showed significant increases in choroidal thickness one week post-vaccination, with values returning to baseline after a month; however, other parameters like retinal thickness experienced significant changes only after the first month.

Objective: To determine whether intravitreal injection of recombinant tissue plasminogen activator (rTPA) is effective for the treatment of refractory diabetic macular edema (DME) in patients who already had posterior vitreous detachment (PVD).

Methods: It is a retrospective chart review of the patients with refractory DME and PVD. The efficacy of intravitreal injection of rTPA was assessed based on the changes in central macular thickness (CMT) and best-corrected visual acuity (BCVA) in these patients.

Purpose: To describe the technique of modified girth-hitch suture for one-side transscleral fixation to rescue a single-haptic dislocation.

Methods: In this surgical technique report, dislocated scleral-fixated posterior-chamber intraocular lenses (IOLs) were secured to the sclera using a 10-0 polypropylene suture looped around the IOL haptic. Three types of IOL were secured in this study (four cases of one-piece polymethyl methacrylate (PMMA) IOL, one case of three-piece acrylic IOL with PMMA loop, and one case of acrylic foldable IOL with a two-plate loop design).

Purpose: To evaluate the choroidal vascular structure in cases of multisystem inflammatory syndrome in children (MIS-C).

Methods: This prospective study included 38 eyes of 19 patients with MIS-C and 60 eyes of 30 healthy participants. Optical coherence tomography (OCT) imaging was performed at 1 month after diagnosis in the MIS-C group.

Purpose: To evaluate the effect of phacoemulsification surgery performed with the nondominant left hand on the corneal endothelium.

Methods: The study included 160 patients who were followed up for at least six months after uneventful cataract surgery. Seventy-seven patients who underwent nondominant left-handed phacoemulsification were evaluated as Group 1 and 83 patients who underwent dominant right-handed phacoemulsification were evaluated as Group 2.

Background: This study aimed to determine the relationship between basal visual acuity (VA) and basal optical coherence tomography (OCT) parameters of patients with idiopathic epiretinal membrane (iERM).

Methods: The study included 200 eyes of 200 patients with iERM. In the evaluation of basal VAs, logMAR 0.

: To enlighten the pathogenesis of silicone oil (SiO)-related complications via measuring aqueous humor levels of electrolytes, nitric oxide (NO), and oxidative stress in SiO, retinal detachment (RD), and control groups. : In this prospective study, 56 patients were grouped as SiO ( = 29), RD ( = 12), and control ( = 15). The results of pre- and post-operative ophthalmological examinations, aqueous humor electrolyte and NO levels, total antioxidant and oxidant status (TAS, TOS) and oxidative stress index (OSI) were analyzed.

Purpose: To assess alterations of retinal layers in healthy subjects over 60 years old.

Methods: Retinal layers of 160 healthy subjects (aged 60-100 years) without any retinal pathology were imaged using spectral domain optical coherence tomography. Mean thickness of retinal nerve fiber layer, ganglion cell/inner plexiform layer (GCLIPL), inner nuclear layer, outer plexiform layer/outer nuclear layer, photoreceptor complex (PR) and retinal thickness (RT) were measured in a 3.

Background/aim: To evaluate the effect of intravitreal pro re nata (PRN) ranibizumab treatment from the start on the best-corrected visual acuity (BCVA) and the central retinal thickness (CRT) in macular edema (ME) due to branch retinal vein occlusion (BRVO).

Materials And Methods: Patients with ME secondary to BRVO, who were treated on a PRN basis after a single intravitreal ranibizumab injection, were retrospectively evaluated. The main outcome measures were changes in BCVA and CRT as measured by optical coherence tomography.

Purpose: To evaluate the effect of cataract surgery on disease activation and visual outcomes in neovascular age-related macular degeneration (AMD).

Methods: In this retrospective case-control study, study arm consisted of neovascular AMD patients, who underwent phacoemulsification surgery. Patients did not have any disease activation at least 6 months before the inclusion, and all had at least 12-month follow-up thereafter.

Aim: To compare the clinical outcomes of combined 25-gauge pars plana vitrectomy (PPV) and phacoemulsification/posterior chamber intraocular lens (PC-IOL) implantation with vitrectomy alone surgery in patients with various vitreoretinal diseases.

Methods: A total of 306 eyes (145 with PPV alone and 161 with phaco-vitrectomy) were enrolled in this retrospective analysis. The surgical approach was 25-gauge PPV combined with phacoemulsification and PC-IOL implantation at the same time in eyes in phaco-vitrectomy group and only PPV in eyes in vitrectomy alone surgery group.

Purpose: To investigate thiol/disulfide status using a novel automated assay in patients with age-related macular degeneration (AMD) compared to age-matched healthy controls.

Methods: A total of 64 AMD patients [51 (79%) non-exudative, 13 (21%) exudative AMD] and 21 age-matched healthy control subjects were enrolled in this study. Plasma total thiol, native thiol, disulfide levels were measured and native thiol/disulfide ratio (TDR) was calculated using a novel spectrophotometric assay.

The purpose of the study is to evaluate the efficacy and safety of as-needed dexamethasone (DEX) retreatment compared with standard DEX retreatment combined with PRN ranibizumab injections among patients with persistent diabetic macular edema (DME). Twenty-eight patients with persistent macular edema having recurrence earlier than 6 months after initial DEX implantation were included in this retrospective study. Group I consisted of 13 patients retreated using monthly PRN ranibizumab injections combined with standard 6-monthly DEX implantation; Group II consisted of 15 patients retreated with DEX implantation earlier than 6 months on an "as-needed" basis.

To investigate the efficacy of single-dose intravitreal dexamethasone implantation in the treatment of persistent diabetic macular edema (DME) unresponsive to 3 consecutive ranibizumab injections over a period of 6 months. Forty-one patients with a previous history of treatment for DME including at least three consecutive intravitreal ranibizumab injections were enrolled in this retrospective study. Main outcome measures were change in best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure from baseline to 6th month.
