J Ophthalmic Vis Res
February 2023
Article Synopsis
- - The study aimed to identify factors associated with keratoconus (KCN) in an Iranian population by comparing 100 KCN patients to 200 age- and sex-matched controls.
- - Key findings indicated that severe eye rubbing, a family history of KCN, vernal keratoconjunctivitis, and parental consanguinity were significant risk factors, while higher socioeconomic status and education levels were linked to a lower incidence of KCN.
- - The results suggest that familial and environmental factors, along with certain systemic diseases, play a critical role in the prevalence of KCN among the population studied.
Aim: To compare the visual results of non-topography-guided and topography-guided photorefractive keratectomy (PRK) applying sequential and simultaneous corneal cross-linking (CXL) treatment for keratoconus.
Methods: Interventional and comparative prospective study. Sixty-nine eyes (36 patients) suffering from keratoconus (stages 1 Amsler-Krumeich classification) were divided into four groups: sequential topography-guided photorefractive keratectomy with CXL, simultaneous topography-guided photorefractive keratectomy with CXL, simultaneous non-topography guided photorefractive keratectomy with CXL, and sequential non-topography guided photorefractive keratectomy with CXL.
Purpose: The purpose of this study was to evaluate the safety and efficacy of blepharoexfoliation in the treatment of Demodex blepharitis.
Methods: Patients with microscopically approved Demodex blepharitis were enrolled. Patients in the treatment group were treated once with in-office blepharoexfoliation (BlephEx LLC; Franklin, TN) using tea tree oil 2% shampoo, followed by eyelid scrubs with tea tree oil 2% shampoo twice a day for 8 weeks.
Effect of mitomycin-C on corneal endothelial cell parameters after refractive surface ablation procedures.

Background: The effect of mitomycin-C (MMC) on the reduction of endothelial cell count in the cornea remains controversial. We aimed to evaluate the effect of MMC on corneal endothelial cell parameters after refractive surface ablation procedures, including photorefractive keratectomy (PRK) and laser epithelial keratomileusis (LASEK).
Methods: In this interventional, comparative, follow-up study, 342 eyes of 171 patients were followed up for 6 months.
Coronavirus disease 2019 (COVID-19) pandemic has caused significant changes in ophthalmic practice. The initial strategy of strict restriction of elective activities has been replaced with various guidelines to revitalize ophthalmic procedures considering the new safety concerns. In this manuscript, we reviewed recent recommendations for ophthalmic practice in different fields of ophthalmology during the COVID-19 pandemic.

Fibrillin, a glycoprotein, is widely expressed throughout the body and contributes to the elasticity and force-bearing capacity of connective tissue. In the eye, fibrillin is a key constituent of the ciliary zonules, which suspend the crystalline lens in place.

Methods: The clinical questions were designed by the guideline team. Websites and databases including National Guidelines Clearinghouse, National Institute for Clinical Excellence, Cochrane, and PubMed were searched to find related CPGs and explore possible answers to the clinical questions.
Purpose: To evaluate the correlation between refractive, corneal, and residual astigmatism and higher order aberrations (HOA) in refractive surgery candidates.
Methods: Three hundred and seventy-five eyes of 188 patients aged 28.2 ± 6.
Purpose: To compare the safety and efficacy of three methods for correcting pre-existing astigmatism during phacoemulsification.
Methods: This prospective, comparative, non-randomized study was conducted from March 2010 to January 2011, and included patients with keratometric astigmatism ≥1.25 D undergoing cataract surgery.
Purpose: To compare the visual outcomes of deep anterior lamellar keratoplasty (DALK) for keratoconus with and without successful big-bubble formation.
Methods: In this retrospective comparative study, a total of 289 consecutive eyes from 257 patients underwent DALK using the big-bubble technique. In cases where the big bubble could not be accomplished, manual stromal dissection down to Descemeton membrane (DM) was performed using a crescent knife.
Purpose: To customize clinical practice guidelines (CPGs) for cataract management in the Iranian population.
Methods: First, four CPGs (American Academy of Ophthalmology 2006 and 2011, Royal College of Ophthalmologists 2010, and Canadian Ophthalmological Society 2008) were selected from a number of available CPGs in the literature for cataract management. All recommendations of these guidelines, together with their references, were studied.
Article Synopsis
- A study in Tehran, Iran aimed to find out how common amblyopia and refractive errors are among primary school children aged 7 to 12, involving 2,410 randomly selected students.
- Results showed that 2.3% of the children had amblyopia, with a higher prevalence in younger kids and in those with specific refractive issues like hyperopia and anisometropia.
- The findings highlight the need for better screening methods and parental awareness regarding the importance of providing glasses for affected children, particularly from the Ministry of Health and insurance support.
Purpose: To identify causes of reduced visual acuity and contrast sensitivity after big-bubble deep anterior lamellar keratoplasty (DALK) in keratoconus.
Design: Prospective interventional case series.
Methods: This study included 36 eyes in 36 patients with keratoconus who underwent DALK using the big-bubble technique.
Background: Ramadan fasting may alter a variety of physiological parameters which by themselves influence ocular system. Here, we review the effects of Ramadan fasting on the health and function of the eye.
Materials And Methods: Literature records in PubMed/MEDLINE, Web of Science, EMBASE, Google Scholar, and Iran Medex databases as well as proceedings of related meetings from January 1986 to March 2014 were systematically reviewed.
A 21-year-old female presented with progressive bilateral visual loss for the past 8 years. The patient had no history of systemic disease, surgery or medications. Complete ophthalmologic examination and topography were performed.

Methods: From 371 myopic eyes of 203 patients who underwent PRK using NIDEK EC-5000 excimer laser with 5.5- to 6-mm ablation zones in Basir Eye Center, Tehran, Iran, during 1997-1998, data of 179 myopic eyes of 98 patients, who participated in annual examinations, were analyzed.
Purpose: To evaluate topographic corneal changes in relatives of patients with keratoconus (KCN).
Methods: In a prospective study, 300 eyes of 150 relatives of 45 patients with KCN were evaluated. Complete slit-lamp examination, refraction, and corneal topography were performed for all eyes.
Purpose: To report the long-term outcomes of penetrating keratoplasty (PKP) in war victims with chronic and delayed mustard gas keratitis.
Methods: This noncomparative interventional case series includes patients with advanced chronic or delayed mustard gas keratitis who had undergone PKP from 1989 to 2006. Best-corrected visual acuity (BCVA), graft clarity, episodes of graft rejection, duration of steroid use, and complications were evaluated.
Purpose: To determine refractive and corneal topographic changes after horizontal rectus muscles recession.
Methods: In a noncomparative interventional case series, 49 eyes of 27 patients were evaluated in two groups: (1) exotropic patients (24 eyes) who underwent lateral rectus muscle(s) recession, and (2) esotropic patients (25 eyes) who underwent medial rectus muscle(s) recession. Full ophthalmic examination including cycloplegic automated refraction was carried out before, 1 and 3 months after surgery.
