Objectives: Iris-claw intraocular lens (IC-IOL) implantation and sutureless scleral fixation of intraocular lenses (SSF-IOL) are two commonly preferred surgical approaches for the management of aphakic patients without sufficient capsular support. The aim of this study was to compare the outcomes of IC-IOL implantation and trocar-assisted SSF-IOL implantation.
Methods: The medical records of secondary IOL implantation patients were retrospectively reviewed.

To investigate the relationship of serum lipoprotein(a) [Lp(a)] and other serum lipids with presence of Graves' ophthalmopathy (GO). A total of 99 consecutive patients diagnosed with Graves' disease (GD), aged 18-65 years, who had not received prior treatment for GO, thyroid surgery, or radioactive iodine therapy, were recruited between June 2020 and July 2022. In addition, 56 healthy controls (HCs) were included as the control group.

Methods: This cohort included 54 patients that underwent combined surgery and received either intracameral triamcinolone acetonide injections ( = 27, IC-TA group) or subconjunctival dexamethasone ( = 27, Sc-Dex group) injections at the end of the surgery. All participants had at least 4 months or longer follow-up.
Purpose: Intravitreal injection of medications induces a sudden increase in posterior segment volume and pushes iris plane anteriorly to narrow iridocorneal angle. The aim of this study to follow and define longitudinal course of these changes following intravitreal injection of 3 different anti-vascular endothelial growth factor (VEGF) medications or dexamethasone implant.
Materials And Methods: This prospective, longitudinal study included 89 eyes of 89 patients that had an intravitreal injection of bevacizumab (n = 20) or ranibizumab (n = 26) or aflibercept (n = 22) or dexamethasone implant (n = 21).
Objective: Corneal incision size has influence both on corneal biomechanics and intracameral fluid dynamics during phacoemulsification cataract surgery. The aim of this study was to evaluate the impact of corneal incision size on endothelial cell loss and surgically induced astigmatism (SIA) following phacoemulsification cataract surgery.
Methods: This prospective, randomized, and comparative study included 61 eyes with senile cataracts.
Purpose: Mucopolysaccharidosis Type I (MPS I) is an autosomal recessive lysosomal storage disorder characterized by a defect in the enzyme alpha-L-iduronidase. Glycosaminoglycan accumulation causes ocular involvement such as corneal clouding or pigmentary retinopathy. Here we report bilateral macular cysts in mucopolysaccharidosis type I (MPS I) that responds to nepafenac treatment.

Methods: This prospective, descriptive study consisted of choroidal hemangioma, choroidal nevus, choroidal melanoma, ocular melanocytoma, congenital hypertrophy of retinal pigment epithelium (CHRPE), and choroidal osteoma. Retinal angiography images were taken by OCTA in a 6 × 6 mm HD scan protocol.
Purpose: To investigate the effect of different types of convergent strabismus on horizontal eye movements and compare data with healthy control subjects.
Materials And Methods: This prospective, cross-sectional study included 38 patients with convergent strabismus (16 fully accommodative, 13 partially accommodative and 9 non-accommodative esotropia) and 19 age-matched control subjects. All of the participants had a detailed ophthalmological examination including visual acuity assessment, cover-uncover prism test, slit lamp, and indirect ophthalmoscopy examination.

Objectives: This study aims to evaluate the effects of acquired esotropia on vestibulo-ocular reflex (VOR) gain in children using video (vHIT) and functional head impulse (fHIT) tests.
Methods: A total of 62 children aged 6-18 years, with acquired esotropia and normal vision, were evaluated in the study. The patients were divided into two sub-groups: accommodative and non-accommodative.
Purpose: To compare the correlations between lamina cribrosa (LC) and related structures with Bruch's membrane opening-minimum rim width (BMO-MRW) and retinal nerve fiber layer (RNFL) thickness in pseudoexfoliation syndrome (PXS) and different stages of pseudoexfoliation glaucoma (PXG).
Methods: This prospective cross-sectional study included 32 PXS eyes of 24 patients and 94 PXG eyes (early-stage (n: 55) and advanced-stage glaucoma (n: 39) of 78 patients. Global and six sectors of RNFL thicknesses and BMO-MRW parameters were measured with enhanced depth imaging (EDI) mode of SD-OCT.
Purpose: Binocular balancing is an important component of refractive correction to avoid asthenopic complaints. Polaroid filters are commonly used for binocular balancing; they rely on subjective examination and cannot represent daily visual activities. We describe a new examination approach to evaluate binocular balance with retinoscopy, which is an objective examination method and does not require strict patient cooperation.

Materials And Methods: This prospective, longitudinal study included 32 eyes of 16 COVID-19 patients and 34 eyes of 17 age-matched healthy control subjects. All the participants had a detailed ophthalmologic assessment, including visual acuity assessment, slit-lamp examination, and indirect ophthalmoscopy.
: To investigate retinal vascular changes in pregnant women using optical coherence tomography angiography (OCTA).: This prospective, cross-sectional study included 97 pregnant women and age-matched 34 healthy control subjects. The OCTA parameters of one eye (left) of pregnancy group and control group were compared.

Methods: This study was conducted using a prospective design. The RNFL thickness alterations of 18 psychiatric patients undergoing ECT were assessed using OCT.

Purpose: This study aimed to compare the optical coherence tomography (OCT) findings of optic pathway glioma (OPG) patients (sporadic or secondary to neurofibromatosis type 1, NF1) with NF1 without OPG patients and healthy controls.
Methods: This was a prospective, case-control study in which 27 patients (13 with OPGs and 14 with NF1 without OPGs) and 13 control subjects were included. The retinal nerve fiber layer (RNFL) thickness, macular thickness, and ganglion cell layer-inner plexiform layer (GCL-IPL) thickness findings measured using OCT and the results were compared between the groups.
Aim: Orbital tissue infections are common infections of childhood that can lead to severe complications. Herein, we aimed to evaluate the etiologic factors, diagnosis, follow-up, and treatment procedures in pediatric patients with orbital infections.
Material And Methods: This study was performed retrospectively between January 2014 and December 2015 in Cerrahpasa Medical Faculty Pediatric Infectious Disease Unit.
Purpose: To report the histologic findings of penetrating keratoplasty buttons in decompensated corneas with toxic anterior segment syndrome (TASS) after a cataract surgery is performed.
Methods: We evaluated the histologic findings of 16 corneal buttons of 16 patients who exhibited decompensation findings because of TASS by means of light microscopy. The patients were classified into 3 groups: The first group consisted of 5 corneal buttons with mild symptoms in which the central corneal thicknesses (CCTs) were ≤650 μm, and the visual acuities (VAs) were ≥0.
