Long-term comparison of horizontal rectus surgery with vertical tendon transposition and combined vertical tendon transposition and inferior oblique-weakening in V-pattern exotropia.

Purpose: To compare the efficacy of bilateral lateral rectus recession with vertical tendon transposition (LRVT) and LRVT combined with inferior oblique (IO) disinsertion for V-pattern exotropia.

Methods: The medical records of patients who had mild-to-moderate (+1 and +2) inferior oblique overaction (IOOA) and underwent half-tendon-width upward LRVT (transposition group), and LRVT with IO disinsertion (combined surgery group) for V-pattern exotropia and who had at least 3 years of postoperative follow-up were reviewed retrospectively.

Results: A total of 45 patients were included: 22 in the transposition group and 23 in the combined surgery group.

Effect of refractive errors on the results of botulinum neurotoxin administration in patients with infantile esotropia.

Purpose: To investigate the effect of refractive errors on the results of patients followed up with infantile esotropia (IE) and treated with botulinum neurotoxin (BNT) injection.

Methods: The files of patients with IE who presented to the ophthalmology pediatric ophthalmology unit and underwent BNT injection into both medial rectus muscles between 2019 and 2021 were reviewed retrospectively. Sixty eyes of 30 patients were included in the study.

Elevated serum fetuin-A levels are associated with grades of retinopathy in type 2 diabetic patients.

Purpose: Fetuin-A is a physiological inhibitor of insulin receptor tyrosine kinase and thus associated with insulin resistance, metabolic syndrome, and an increased risk for type 2 diabetes mellitus (T2DM). This study aims to investigate the possible relation between the serum fetuin-A levels and the stages of diabetic retinopathy (DR) in patients with T2DM.

Methods: This prospective study included 82 patients with T2DM and 19 age- and gender-matched healthy controls (HCs) (group 1).

Increased cancer risk in patients with periodontitis.

Background: Previous studies have noted a possible association between periodontal diseases and the risk of various cancers. We assessed cancer risk in a cohort of patients with moderate to severe periodontitis.

Methods: Patients diagnosed with moderate to severe periodontitis by a periodontist between 2001 and 2010 were identified from the hospital registry.

Long-term changes in subfoveal choroidal thickness and central macula thickness after Nd:YAG laser capsulotomy.

Purpose: To evaluate changes in central macula thickness (CMT), subfoveal choroid thickness (SCT), and intraocular pressure (IOP) before and after neodymium:yttrium-aluminum-garnet (Nd:YAG) laser capsulotomy.

Methods: 42 eyes of 42 patients who underwent Nd:YAG laser capsulotomy were included in this prospective study. CMT, SCT, and IOP were evaluated preoperatively and at postoperative week 1 and postoperative months 1, 3, 6, and 12.

Bacteriological profile in conjunctival, lacrimal sac, and nasal specimens and conjunctival normalization time following external, endoscopic, and transcanalicular multidiode laser dacryocystorhinostomy.

Purpose: To compare the conjunctival, lacrimal sac, and nasal flora cultures and conjunctival normalization time following external (EX-), endoscopic (EN-), and transcanalicular multidiode laser (TC-) dacryocystorhinostomy (DCR) and to evaluate the relationship between culture positivity and surgical success. We further performed antibiotic sensitivity analyses for lacrimal sac culture samples.

Methods: A total of 90 patients with primary acquired nasolacrimal duct obstruction were recruited and divided into EX-DCR (n=32), EN-DCR (n=28), and TC-DCR (n=30) groups.

Relationship between Altered Platelet Morphological Parameters and Retinopathy in Patients with Type 2 Diabetes Mellitus.

Purpose. To investigate whether platelet morphology or function is altered in patients with diabetic retinopathy (DR). Methods.

Long-Term Changes in Subfoveal Choroidal Thickness After Cataract Surgery.

BACKGROUND Cataract surgery is associated with the development of late-onset age-related macular degeneration (AMD). The pathogenic mechanism is still not fully established. The purpose of this study was to evaluate the possible changes in central macula thickness (CMT) and subfoveal choroid thickness (SCT) after uneventful cataract surgery.

Comparison of scanning electron microscopy findings regarding biofilm colonization with microbiological results in nasolacrimal stents for external, endoscopic and transcanalicular dacryocystorhinostomy.

Aim: To compare bacterial biofilm colonization in lacrimal stents following external dacryocystorhinostomy (EX-DCR), endoscopic dacryocystorhinostomy (EN-DCR), and transcanalicular dacryocystorhinostomy (TC-DCR) with multidiode laser.

Methods: This prospective study included 30 consecutive patients with nasolacrimal duct obstruction who underwent EXT-, EN-, or TC-DCR. Thirty removed lacrimal stent fragments and conjunctival samples were cultured.

Prospective comparison of 3 dacryocystorhinostomy surgeries: external versus endoscopic versus transcanalicular multidiode laser.

Purpose: To analyze the clinical outcomes of external (EX-), endoscopic (EN-), and transcanalicular multidiode laser (TC-) with dacryocystorhinostomy (DCR).

Methods: Ninety-two patients with primary acquired nasolacrimal duct obstruction were enrolled (divided into EX-DCR [n = 33], EN-DCR [n = 30], and TC-DCR groups [n = 29]) in this prospective study. Primary outcome measures were the anatomical and functional success of operations at the last control examination.

Twenty-four hour pattern of intraocular pressure and ocular perfusion pressure in night shift workers.

Purpose: To investigate the intraocular pressure (IOP) and ocular perfusion pressure (OPP) in night shift workers.

Methods: Seventy-one healthy individuals who work the night shift were evaluated. IOP and OPP were measured in the sitting position in each participant.

Optic disc pit with sectorial retinitis pigmentosa.

Sectorial retinitis pigmentosa (RP) and optic disc pit (ODP) are rare clinical conditions. We present a 40-year-old woman with a history of mild night blindness and decreased vision in the right eye for about 5 years. Fundus examination revealed retinal pigmentary changes in the superior and inferotemporal sectors covering the macula and reduced arterial calibre and ODP at the temporal edge of the optic disc.

Pasteurella canis and Granulicatella adiacens conjunctivitis outbreak resistant to empirical treatment in a child welfare agency.

Purpose: To investigate pathogens associated with bacterial conjunctivitis resistant to the empirical treatment and their antibiotic resistance in a child welfare agency.

Methods: Twenty-eight eyes in 14 children with a median age of 3 months with conjunctivitis resistant to the empirical treatment were included in this study. Samples were taken three times from the inferior fornix in both eyes using cotton swabs, cultured onto chocolate and blood agar, and prepared for Gram staining.

Range resolved lidar for long distance ranging with sub-millimeter resolution.

A lidar technique employing temporally stretched, frequency chirped pulses from a 20 MHz mode locked laser is presented. Sub-millimeter resolution at a target range of 10.1 km (in fiber) is observed.

Boron removal from geothermal waters by electrocoagulation.

Most of the geothermal waters in Turkey contain extremely high concentration of boron when they are used for irrigation. The use of geothermal waters for irrigation can results in excess amount deposition of boron in soil. On the other hand, a minimal boron concentration is required for irrigational waters.

Adsorption of boron from boron-containing wastewaters by ion exchange in a continuous reactor.

In this study, boron removal from boron-containing wastewaters prepared synthetically was investigated. The experiments in which Amberlite IRA 743, boron specific resin was used were carried out in a column reactor. The bed volume of resin, boron concentration, flow rate and temperature were selected as experimental parameters.

Supermode suppression to below -130 dBc/Hz in a 10 GHz harmonically mode-locked external sigma cavity semiconductor laser.

We demonstrate supermode suppression to levels below -125 dBc/Hz and -132 dBc/Hz using Fabry-Perot etalons with finesse values of 180 and 650, respectively, for a 10 GHz harmonically mode-locked external sigma cavity semiconductor laser. The laser was hybridly mode-locked using direct electrical modulation in a compact package without the need for an external modulator.
