Trabeculectomy for normal tension glaucoma

This is a retrospective consecutive, non-comparative case series of 131 eyes of 98 patients undergoing trabeculectomy between 2007 and 2013 in a normal tension glaucoma (NTG) clinic. Assessment of the clinical outcomes include intraocular pressures (IOP) reduction, bleb formation, final...

Update on primary angle closure glaucoma

This review article considers primary angle-closure glaucoma which is responsible for half of glaucoma-related blindness worldwide. Angle closure is characterised by appositional contact between the iris and trabecular meshwork. It tends to develop in eyes with shallow anterior chambers, anteriorly...

Differential diagnosis in cases of suspected neuroretinitis

Neuroretinitis is a form of optic neuropathy typically characterised by acute unilateral visual loss with optic disc oedema and macular exudates arranged in a star figure around the fovea (complete or partial star). The purpose of this study was to...

A case report of visual loss as a consequence of coeliac disease

The authors present a case of permanent visual loss secondary to occipital lobe calcification in coeliac disease, the first reported such case. The 58-year-old man had been diagnosed with coeliac disease 20 years prior to his visual investigations and had...

Using OCT to screen and monitor Alzheimer’s disease

Alzheimer’s disease (AD) is a neurodegenerative illness characterised by progressive decline in cognitive function. AD is the main cause of dementia worldwide. Over recent years researchers have strived to find biomarkers to diagnose AD, particularly in the early stages of...

Fungi in chronic anterior blepharitis

In this prospective, non-randomised cross-sectional study the authors demonstrate the presence of fungi in patients with chronic anterior blepharitis of at least two years duration. Eyelash samples were obtained by epilation with sterile forceps and evaluated with PAS staining, fungal...

Iranian strabismus prevalence

This study aimed to evaluate the prevalence of heterotropia and heterophoria in Iran. This was a cross-section study undertaken in 2013 with the target population of grade 1 (seven-year-old) children. Seven cities across different geographical locations were included with multistage...

Three methods of suppression measurement

Test-retest reliability and interchangeability are evaluated for three filter bars available to measure density of suppression: Sbisa bar, Bagolini filter (BF) bar and neutral density filter (NDF) bar. The study involved 10 strabismic adults. Testing conditions were altered and effects...

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...

Association of asthenopia and heterophoria

Heterophoria varies over time and asthenopic symptoms may be greater when the heterophoria is larger. Thus a close intra-individual correlation may exist between heterophoria and discomfort during reading. The authors investigated the variability of both parameters in 20 individuals who...

Persian AS20 validation

The authors developed a Persian version of the AS20 questionnaire and used the new version to evaluate the effect of strabismus surgery on health-related quality of life. Two independent bilingual translators translated the English version AS20 into Persian. The two...
