PURPOSE: Various vitrectomy probes are currently being used commercially, and there are ongoing efforts toward developing probes with higher cutting rates and smaller gauges. This study aimed to compare the efficiency and safety of various commercially available small gauge ultra-high speed dual pneumatic vitrectomy probes. METHODS: We retrospectively analyzed the medical records of patients and recorded intraoperative videos while they underwent microincision 3-port vitrectomy surgery for idiopathic epiretinal membrane (ERM) at Soonchunhyang University Seoul Hospital...

PURPOSE: To investigate the prevalence ratio of primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG) in the Asian population. METHODS: Systematic searches of PubMed, Embase, and Cochrane databases for population-based studies in Asia published until August 5, 2022. We conducted a meta-analysis for PACG to POAG prevalence ratio using inverse variance-weighted random-effects meta-analyses so as to combine the study-specific measures of association...

PURPOSE: To compare topical and peribulbar anaesthesia in cataract surgery for hemodynamic changes, rate of complications and pain score in patients with cardiovascular disease. MATERIAL AND METHODS: A prospective comparative study at a tertiary care centre in India. Patients > 40 years old with treated/controlled hypertension and cardiovascular disease scheduled for cataract surgery under topical or peribulbar anaesthesia were recruited. Heart rate, blood pressure (BP), and ophthalmic and systemic complications were noted: preoperatively, immediately after block, intra-operatively, immediately postoperatively and one hour postoperatively...

BACKGROUND: In the present study, we determined the prevalence of obstructive meibomian gland dysfunction (MGD), hyposecretory MGD, grossly normal MG, and hypersecretory MGD in patients with dry eye syndrome using lipid layer thickness (LLT) and meibomian gland dropout. METHODS: Eighty eight patients with dry eye syndrome were included in the study. Patients were categorized into four groups according to the LLT and weighted total meiboscore. The proportion of patients in each group was calculated...

PURPOSE: To investigate the characteristics of subfoveal nodules in Korean patients with Coats' disease and their association with visual outcomes Method: A retrospective analysis was conducted within the medical records of patients with Stage 2B or 3A1 Coats' disease, including clinical features, imaging, presence of either a subfoveal nodule or macular fibrosis, and visual outcome. RESULTS: Twelve patients were present with Stage 2B or 3A1 Coats' disease, and 9 patients (75%) presented with subfoveal nodule...

PURPOSE: We aimed to compare the accuracy of the IOL calculation formula using the standard keratometry (K) and total keratometry (TK) during the femtosecond laser-assisted cataract surgery (FLACS) with a monofocal intraocular lens (IOLs) with enhanced intermediate function using currently used formulas. METHODS: A retrospective review of 125 eyes of 125 patients who had undergone FLACS with implantation of monofocal IOL with enhanced intermediate function was conducted...

PURPOSE: This study aimed to assess the difference in the vascular parameters of perfusion in the optic nerve head (ONH) in normal tension glaucoma (NTG) across disease stages using optical coherence tomography angiography (OCTA) and its correlation with peripapillary retinal nerve fiber layer (RNFL) thickness. METHODS: In this retrospective study, 83 eyes with varying stages of NTG (25 mild, 31 moderate, and 27 severe) and 90 healthy eyes were enrolled. The perfusion density (PD) and flux index (FI) of the ONH divided into four sectors were determined...

AIM: To compare stab and eyelid crease incision techniques in revision frontalis sling surgeries using silicone rods. METHODS: This retrospective study involved 52 eyes in 48 consecutive pediatric patients who underwent revision frontalis sling surgery between 2008 and 2019. All primary surgeries were performed by making eyelid crease incisions and suturing of silicone rods onto the tarsal plates. The revision surgeries were performed by either making stab incisions over the eyelid through which to pass the silicone rods (group A), or by refixing the same or a new silicone rod to the tarsal plate (group B)...

PURPOSE: The aim of this study is to investigate changes in intraocular pressure (IOP) and anterior segment parameters before and after cataract surgery, vitrectomy, and combined surgery. METHODS: The records of patients who had undergone cataract surgery (cat group), vitrectomy (vit group), or combined cataract surgery and vitrectomy (combi group) at our hospital were retrospectively examined. Vit group consisted of Pseudophakic eyes. IOP and anterior segment measurements, including anterior chamber depth (ACD), angle opening distance (AOD), trabecular-iris angle (TIA), and trabecular-iris space area (TISA), were measured using swept-source anterior segment optical coherence tomography before and six months after surgery in 41, 15, and 40 eyes, respectively...

BACKGROUND: To investigate the flow characteristics using different thresholding methods on a choriocapillaris optical coherence tomography angiography (OCTA) image complemented with a structural en-face image. METHODS: The 42 choriocapillaris OCTA images from healthy subjects were obtained with swept-source OCTA device (Zeiss Plex-Elite) and the 3 x 3 mm area OCTA images were processed with Image J. Using a raw choriocapillaris OCTA image and structural en-face image, we adjusted the different structural signal intensity...

PURPOSE: The aim of this study is to determine the mean central corneal thickness (CCT) and mean intraocular pressure (IOP) in children with type 1 diabetes mellitus (T1DM) and to determine the relationship between CCT and IOP on the one hand and age, sex, retinopathy hemoglobin A1c (HbA1c), and duration of diabetes on the other. METHODS: This is a case-control, hospital-based study conducted at Hospital Universiti Sains Malaysia between January and November 2022...

PURPOSE: To investigate the relative risks (RRs) for dementia among individuals with glaucoma. METHODS: We conducted a search of PubMed, Web of Science, Scopus, and Cochrane databases for observational cohort studies examining the association between glaucoma and dementia until March 2023. Two authors independently screened all titles and abstracts according to predefined inclusion and exclusion criteria. Pooled RR and 95% confidence intervals (CIs) were generated using random-effect models...
