Iranian prevalence of convergence / accommodative disorders
The aim of this study was to investigate the frequency of accommodative and convergence disorders in an optometric clinical population and ascertain tests with the highest sensitivity and specificity in detecting these anomalies. The authors gathered information on symptoms, near...
Associations of esotropia with shunts
This study explored the characteristics and outcomes of children with esotropia and ventriculo-peritoneal (VP) shunt placement due to hydrocephalus. The authors conducted a retrospective study of 16 patients (nine female, seven male) aged three months to 5.6 years (mean 17...
Central corneal and epithelial thickness measured by Fourier domain OCT
This study examined intraobserver and interobserver reproducibility of corneal thickness (CT) and epithelial thickness (ET) measurement of Fourier domain OCT (RTVue) in 23 healthy volunteers. RTVue is capable of producing 26,000 A scans per second with depth resolution of 5µm....
Association of astigmatism and inferior oblique over action
The aim of this study was to evaluate the association between primary inferior oblique over action and astigmatism along the axis on the overacting muscle. The authors explored the postoperative change in axis of astigmatism and cylinder power in a...
Proprioception and ptosis
This is a small prospective study investigating the effect of proprioceptive factors on upper lid height. Eight unilaterally anophthalmic patients with ocular prostheses and normal lid heights had standardised photographic measurements taken of their eyelid and brow positions. Three sets...
Intravenous paracetamol in orbital surgery
This is a large prospective study of the effect of intravenous acetaminophen (paracetamol) in orbital surgery. The study included three groups of 50 patients. One group had no i.v. paracetamol, the second 1g of i.v. paracetamol within 30 minutes of...
Prophylaxis for clinical macular oedema after phacoemulsification
The authors report on a retrospective cohort study looking at three different prophylaxis methods for macular oedema after cataract surgery: 1) Topical prednisolone acetate (PA) alone; 2) Topical PA in combination with non-steroidal anti-inflammatory drug (NSAID); 3) Intraoperative subconjunctival injection...
Anterior segment OCT predicts gonioscopic angle closure
This is a prospective observational study of 342 subjects over four years. Sixty-five were controls who had open angles both on gonioscopy and AS-OCT, while 277 had open angles only on gonioscopy but iridotrabecular contact (ITC) on AS-OCT (one to...
PD-1 and retinal ganglion cell death
Death of retinal ganglion cells (RGC) in conditions like glaucoma leads to permanent visual loss. RGC death can be due to the initial stress such as raised intraocular pressure or secondary to mechanism such as oxidative stress. Programmed cell death-1...
Statins inhibit TGFβ2 mediated fibrotic response in astrocytes
Glaucoma is a common condition where increased ocular pressure can lead to death of retinal ganglion cells due to impaired drainage of fluid from the eye. One mechanism involved in glaucoma is remodelling of the extracellular matrix at the lamina...
Association between colour vision impairment and amyotrophic lateral sclerosis (ALS)
The purpose of this study is to test the hypothesis that colour vision impairment is associated with amyotrophic lateral sclerosis (ALS). Abnormalities of the inner and intermediate retinal structures in patients with ALS have been described using optical coherence tomography...
