Implementation of thyroid eye disease registry in Iran: rationale and research protocol.

Background: To describe the implementation of a registry system for patients with thyroid eye disease (TED) in Iran to obtain more information about its nature, prevalence, and annual incidence, as well as extend insight into the etiology, pathogenesis, and eventually make an accurate prognosis of different medical or surgical treatment methods.

Methods: After receiving approval from the Disease Registry Committee of Iran University of Medical Sciences (IUMS) in 2019 and the Ministry of Health and Medical Education (MOHME) in 2020, the protocol was introduced in three consecutive phases at regional, provincial and national levels. The establishment of a registry committee in Rassoul Akram Hospital, one of the medical centers affiliated to IUMS, was the first step to organizing the registry project's main core.

The correlation between humoral immune responses and severity of clinical symptoms in COVID-19 patients.

The SARS-CoV-2 pandemic persists with global repercussions. Initial COVID-19 symptoms encompass pneumonia, fever, myalgia, and fatigue. The human immune system produces IgM and IgG antibodies in response to SARS-CoV-2.

Impact of COVID-19 on the patient referral pattern and conversion rate in the university versus private facial plastic surgery centers.

Purpose: To compare the number of referrals and conversion rate between the pandemic and pre-pandemic period.

Methods: The number of referrals and conversion rate between the 10-month pandemic (March-December 2020) and pre-pandemic (March-December 2019) were evaluated in the two university (mainly non-cosmetic) and private (mainly cosmetic) facial plastic surgery centers. Demographics and monthly number and type (cosmetic and non-cosmetic) of the referrals and surgeries were recorded from the both and cosmetic facial injections (botulinum toxin and filler) and the source of referrals (web- and non-web-based) from the private center.

A Systematic Review on the Role of Antioxidants in Thyroid Eye Disease.

Purpose: To systematically review the role of antioxidants in management of patients with thyroid eye disease (TED).

Methods: A literature search of the electronic databases was performed without restrictions on the date of publication till the end of March 2021, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Clinical trials, case-control studies, cohorts, case series, case reports, and experimental (including ) studies in the English language were included.

Optic Nerve Head Vessel Density Changes from Graves' Disease without TED to TED Dysthyroid Optic Neuropathy: Does Optic Nerve Head Ischemia Play a Role?

Purpose: To compare the retinal peripapillary capillary (RPC) vessel density (VD) between 5 groups of patients on the spectrum of thyroid eye disease (TED).

Method: This is a prospective comparative study looking at 5 groups of patients who were consecutively included from January 2018 to March 2021. They were composed of: Healthy volunteers (39 eyes and 20 subjects), patients with Graves' disease without TED (26 eyes and 13 patients), mild TED (28 eyes and 14 patients), moderate-severe TED (30 eyes and 17 patients), and TED with dysthyroid optic neuropathy (DON) (21 eyes and 12 patients).

Safety of the subconjunctival injection of doxycycline in rabbits.

To evaluate the safety of subconjunctival injection of doxycycline in rabbit eyes. Eight white New Zealand rabbits were selected. Different concentrations of 250 micrograms (μg), 500 μg, 1000 μg, and 2000 μg in 0.

Intravitreal injection of a Rho-kinase inhibitor (fasudil) combined with bevacizumab versus bevacizumab monotherapy for diabetic macular oedema: a pilot randomised clinical trial.

Unlabelled: Click here to listen to the Podcast BACKGROUND/AIMS: To compare the efficacy of combined intravitreal injection of bevacizumab and a Rho-kinase inhibitor, fasudil (intravitreal bevacizumab (IVB)/intravitreal fasudil (IVF)), with IVB alone for centre-involving diabetic macular oedema (DME).

Methods: In this prospective randomised clinical trial, 44 eyes with centre-involving DME were randomised into two groups. The combined group received three consecutive injections of IVB (1.

Association of Socio-Economic Status and Visual Impairment: A Population-Based Study in Iran.

Backgrounds: To assess the role of socio-economic inequality in visual impairment (VI) in Varamin district, Iran.

Patients And Methods: Using multistage cluster sampling method, 60 clusters (each with 50 subjects) were recruited and underwent clinical eye examinations. Socio-economic status (SES) was identified based on education, occupation, family assets and housing conditions that were measured at the participants' households using a semi-structured questionnaire and a two-step cluster analysis model.

A Possible Role for LTBP2 in the Etiology of Primary Angle Closure Glaucoma.

Purpose: To assess the association of LTBP2 mutations with primary angle closure glaucoma (PACG).

Methods: We studied 54 unrelated patients with PACG and one individual with pseudoexfoliation accompanied with angle closure glaucoma; these consisted of 28 female and 27 male subjects aged 27 to 82 (mean, 63) years. The 36 exons and flanking intronic sequences of LTBP2 in all patients were amplified by PCR and sequenced by the Sanger protocol.

Intrasubject Difference in CCT among POAG versus Normal Individuals.

Purpose: To evaluate intrasubject asymmetry in central corneal thickness (CCT) among patients with primary open-angle glaucoma (POAG) as compared with that of normal subjects and to determine whether the eye with thinner cornea has more severe glaucomatous visual field damage.

Methods: In this case-control study, CCT of both eyes was measured using an ultrasonic pachymeter (UP-1000; Nidek Technologies, Gamagori, Japan) among POAG patients and normal subjects. The intrasubject difference in CCT was calculated and compared between the study groups; correlations between CCT and intraocular pressure (IOP), vertical cup-to-disc ratio (VCDR), and visual field defects were also evaluated.

"Planning eye health services in Varamin district, Iran: a cross-sectional study".

Background: A recent survey of avoidable blindness in Varamin District, Iran, identified moderately high levels of visual impairment (10%) and blindness (1.5%) in people >50 years. This study aimed to define current provision, identify gaps and suggest practical solutions for improving eye health services in this area.

Biometric parameters in different stages of primary angle closure using low-coherence interferometry.

Purpose: To compare ocular biometric parameters using low-coherence interferometry among siblings affected with different degrees of primary angle closure (PAC).

Methods: In this cross-sectional comparative study, a total of 170 eyes of 86 siblings from 47 families underwent low-coherence interferometry (LenStar 900; Haag-Streit, Koeniz, Switzerland) to determine central corneal thickness, anterior chamber depth (ACD), aqueous depth (AD), lens thickness (LT), vitreous depth, and axial length (AL). Regression coefficients were applied to show the trend of the measured variables in different stages of angle closure.

Comparison of three phakic intraocular lenses for correction of myopia.

Purpose: To compare the visual outcomes and complications of three different types of phakic intraocular lenses (PIOLs), for correction of moderate to high myopia.

Methods: We reviewed 112 myopic eyes undergoing PIOL implantation using Artisan (40 eyes), Artiflex (36 eyes), and implantable collamer lens (ICL, 36 eyes). Best corrected visual acuity (BCVA), intraocular pressure (IOP), pachymetry, corneal endothelial cell (CEC) loss, and higher order aberrations (HOA) were compared.

Prevalence of angle closure in siblings of patients with primary angle-closure glaucoma.

Purpose: To determine the frequency of angle closure in siblings of patients with primary angle-closure glaucoma (PACG).

Methods: In this cross-sectional observational study, siblings of consecutive patients with PACG underwent a comprehensive ophthalmologic examination, including slit-lamp biomicroscopy, measurement of intraocular pressure, stereoscopic optic nerve head examination, and dynamic gonioscopy. Ultrasonic pachymetry was obtained in all subjects; peripapillary retinal nerve fiber layer thickness measurement by optical coherence tomography and standard achromatic perimetry were performed in subjects with angle closure, categorized as primary angle-closure suspect (PACS), primary angle closure (PAC), and PACG, or any suspicion of glaucoma in the presence of open angles.
