Article Synopsis
- - The study aimed to assess long-term structural changes in the anterior chamber (AC) angle after a specific glaucoma surgery called gonioscopy-assisted transluminal trabeculotomy (GATT).
- - Ten eyes that had undergone GATT at least six years prior were examined, revealing various cleft appearances (open, closed, segmentally open) and a noteworthy trend of the trabecular flap moving toward the incision site, resulting in some clefts appearing closed over time.
- - The researchers concluded that combining anterior segment optical coherence tomography (AS-OCT) with gonioscopy provided valuable insights into these structural changes, with mostly preserved clefts in the superior part of the AC angle long-term.
Various neurological complications have been reported after COVID-19. The study aimed to document an unusual case of Adie's tonic pupil following COVID-19. The study was a case report.

Methods: In this retrospective comparative study, consecutive patients with POAG or PEXG who underwent GATT or TRAB by a single surgeon and with a follow-up period of at least 1 year were included. Surgical success rates, change in best-corrected visual acuity, IOP, the need for antiglaucoma medication, surgical complications, and the need for additional glaucoma surgery were compared.
Objectives: The objective of this study was to analyze the changes in the effective optical zones (EOZ) using topographic techniques on the tangential curvature difference map at post-operative 1-year following transepithelial photorefractive keratectomy (T-PRK) and to identify parameters linked to the EOZ alterations.
Methods: The study comprised 55 eyes of 55 myopic patients who underwent T-PRK. EOZs were measured using the tangential curvature difference map of the Scheimpflug tomography system.
Purpose: To compare the effective optical zones (EOZs) of small-incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (F-LASIK) by utilizing topographic methods on the tangential curvature difference map at postoperative 1 year and to identify parameters linked to the EOZ alterations following both surgeries.
Methods: Myopic patients who underwent SMILE or F-LASIK were included in the study. Patients with refractive error greater than -9.
Purpose: To determine the effect of phacoemulsification surgery, which is one of the types of cataract surgery by using ultrasonic power to break up the crystalline lens and clean it with vacuum, on anterior chamber flare (ACF) and choroidal vascular index (CVI).
Methods: For this cross-sectional study, patients were included if they had cataract with nucleus hardness grade 2 or 3, no systemic inflammatory disease, and not use of anti-inflammatory drugs/prostaglandins preoperatively. ACF using a laser flare meter and CVI in patients underwent uncomplicated phacoemulsification was recorded preoperatively, on the postoperative 1st day, 1st week, and 1st month.
Purpose: To evaluate the long-term clinical outcomes, safety and efficacy of Eyecryl posterior-chamber phakic intraocular lens implantation (pIOL) implantation in patients with high myopia.
Methods: Patients with myopia between -6.00 and -20.
Prcis: Transscleral diode laser cyclophotocoagulation (TDLC) is effective and safe in a large population and different types of glaucoma but is least effective in the neovascular glaucoma (NVG) group.
Objective: We aimed to investigate the clinical outcomes of TDLC in a large cohort of patients with different types of refractory glaucoma.
Patients And Methods: Using patient charts, we retrospectively analyzed the success and complications of TDLC performed on eyes categorized into 6 groups: primary glaucoma (116 eyes), trauma (41 eyes), NVG (84 eyes), post-vitreoretinal surgery (post-VRS, 79 eyes), penetrating keratoplasty (47 eyes), and miscellaneous (40 eyes).
Prcis: In unilateral pseudoexfoliation glaucoma (PEXG), there may be decreased choroidal vascularity index (CVI), radial peripapillary capillary plexus' perfusion and flow. CVI may also be reduced in fellow eyes, suggesting that PEXG is bilateral disease.
Purpose: Evaluation of peripapillary and macular choroidal microvascularity and radial peripapillary capillary plexus in both eyes with unilateral PEXG and healthy eyes.
Purpose: To evaluate the changes in peripapillary microvascularity in idiopathic intracranial hypertension (IIH) and optic disc drusen (ODD) patients, by comparing them with those in healthy individuals, via optical coherence tomography angiography (OCTA).
Methods: Sixty-two eyes of 33 patients with ODD, 58 eyes of 30 patients with IIH, and 70 eyes of 70 healthy people were imaged for 6 × 6-mm optic disc scans on a spectral-domain OCTA. Vascular densities in superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris (CC) of ODD, IIH, and healthy eyes were compared with a one-way analysis of variance.
Purpose: To evaluate the long-term refractive outcomes of Eyecryl posterior chamber spherical phakic intraocular lens (pIOL) implantation in high myopia and endothelial cell density (ECD) change.
Setting: Beyoglu Eye Training and Research Hospital, Istanbul, Turkey.
Design: Retrospective.
Clinical Relevance: In myopic eyes, the optic disc may become tilted and rotated, making glaucoma diagnosis more difficult.
Background: To determine the presence of tilted optic disc, the degree of optic disc rotation, and their effects on the angular location of superotemporal and inferotemporal retinal nerve fibre layer (RNFL) peaks in healthy myopic Caucasians.
Methods: Non-glaucomatous healthy myopic Caucasian eyes with an axial length > 24 mm were evaluated.
Prcis: Retinal nerve fiber layer (RNFL) thickness is helpful in the diagnosis of glaucoma in myopic eyes but neuroretinal rim (NRR) thickness is the most valuable measure. However, changes in optical coherence tomography angiography (OCT-A) parameters are insufficient for the diagnosis of mild to moderate glaucoma in myopia.
Purpose: To detect how a multimodal evaluation, which includes RNFL, NRR thickness, and optic nerve head (ONH) OCT-A, affects glaucoma diagnosis in myopic patients.
Prcis: The choroidal vascularity index (CVI) is a new marker for the choroid. The decrease in CVI following latanoprost use can provide a better understanding of the pathogenesis of the posterior segment side effects of latanoprost such as cystoid macular edema and central serous choroidopathy.
Purpose: The purpose of this paper is to evaluate the changes in the CVI, total choroidal area (TCA), stromal area (SA), luminal area (LA), and choroidal thickness (CT) following latanoprost therapy in patients with primary open angle glaucoma and ocular hypertension.
Background: To compare the changes in anterior chamber laser flare after phacoemulsification and intraocular lens implantation according to phaco parameters in eyes with and without pseudoexfoliation syndrome.
Methods: Patients (39 without pseudoexfoliation (PEX), 28 with pseudoexfoliation) who underwent the surgery with the same device (Centurion System, Alcon Laboratories, USA) and same experienced surgeon were divided according to the presence of PEX. Anterior chamber laser flare was assessed using a laser flare meter (Kowa-FM700, Kowa Company, Japan) by the same blinded researcher.
Background: To evaluate the microvascularity and choroidal vascularity index (CVI) using optical coherence tomography angiography (OCTA) and OCT following femtosecond laser-assisted in-situ keratomileusis (FS-LASIK) and small incision lenticule extraction (SMILE) procedures.
Methods: Patients with myopia (<-6.0D sphere) or myopic astigmatism (<-4.
Purpose: To evaluate the changes in retinal microvasculature in eyes with anterior uveitis (AU) using optical coherence tomography angiography.
Methods: Foveal avascular zone (FAZ) of superficial capillary plexus (SCP) and deep capillary plexus (DCP), vessel density (VD) of SCP, DCP, and choriocapillaris, and central macular thickness (CMT) and central foveal thickness (CFT) were calculated from 34 healthy and 41 uveitic eyes. The parameters were compared between the two groups.
