The rheumatological diseases known as spondyloarthropathies (SpAs) are reviewed with respect to the current classifications of SpAs and from the perspective of ophthalmic practitioners. The focus is on the most common spondyloarthropathy, ankylosing spondylitis (AS), and the key symptoms, such as inflammatory back pain. The association with HLA-B27...
ABSTRACTA sample of 13,784 patients attending an optometric practice generated 277 (2.0% referrals of previously undiagnosed conditions to ophthalmologists. The reasons for these referrals were grouped according to the site of the anomaly and the frequency of occurrence expressed as a percentage of the sample and the rate per 1,000 patients. Those...
The referral criteria for optometric patients with vascular hypertension are discussed. It is recommended that casual blood pressures of 140/90 mm Hg for 18–44 years, 150/90 mm Hg for 45–64 years, and 160/95 mm Hg for 65 years are the lower limits of referral. These criteria should be modified in the presence of fundus signs or associated risk fact...
Data on the prevalence of all ocular conditions seen in 1500 consecutive optometric patients were obtained during an investigation into the effectiveness of routine visual field screening. In many instances, these are the first prevalence figures for optometric patient populations. Some of the estimates of prevalence are compared with other optomet...
Some strategies for rapid investigation of the visual fields are reviewed. Those aspects considered are the testing of central and peripheral fields, the pattern and density of sampling the visual field with static stimuli and the most suitable stimulus intensity at which to begin the screening of each subject. Some of the design features of 10 vis...
A patient with a history of longstanding opaque cataract and a white pupil reported a return to a black pupil, which was the result of lens subluxation. The case was complicated by optic nerve coloboma of the Morning Glory syndrome type and a total retinal detachment.
A 60-year-old male with a history of migraine presented with evidence of branch retinal arterial occlusion that developed at the time of an attack of retinal migraine. The diagnosis of branch arterial occlusion secondary to migraine was made after exclusion of numerous possible medical conditions. The possible role of vasospasm in this condition is...
Acute anterior uveitis is an important ocular disease of considerable interest to therapeutically and non-therapeutically qualified optometrists. This review examines the role of optometrists in the primary care setting and gives guidelines for appropriate care of patients with anterior uveitis. Diagnosis and differentiation from other forms of ant...
A case of two macroaneurysms on the same retinal arteriole is presented. After observation of these lesions for some weeks, an increased threat to the macula from oedema led to laser photocoagulation. Although treatment did not hasten resolution, the patient has remained asymptomatic. The aetiology and natural history of macroaneurysms are discusse...
A 43-year-old patient presenting with a highly congruous homonymous hemianopia was shown by neuro-imaging to have a very large arteriovenous malformation of the brain. The significance of finding this visual field defect, its unusual cause and the absence of symptoms other than longstanding migraine with aura are discussed.
Eyelashes can be observed in unusual anatomical locations after falling out of their hair follicles. Loose lashes can inadvertently enter a lacrimal punctum or widi more difficulty, a Meibomian gland orifice They may even penetrate through anterior surface layers such as the conjunctiva or skin of die lid. There may be some diagnostic problems, occ...
About 20 per cent of women and 10 per cent of men experience migraine at some time in their lives, of whom about one half to two thirds will have had a migraine attack in the previous 12 months. Prevalences of this order have been found in a survey of patients in an Australian optometric practice. Between one third and one half of migraineurs exper...
The purpose of the investigation was to determine the prevalence of migraine in optometric practice and to document the variety of presentation. One thousand consecutively presenting patients of a suburban optometric practice were asked questions to establish whether they experience migraine or have experienced it in the past. Those with a history...
To highlight a possible causal effect of eye rubbing in the etiology of keratoconus.
A 43-year-old man presented to the practice of one of the authors (I.F.G.) with the complaint of gradual onset reading difficulty. History revealed the patient to have experienced constant epiphora in the right eye throughout his life as a result of punctal agenesi...
BACKGROUND: A significant proportion of patients diagnosed under the broad classification of open angle glaucoma actually has normal tension glaucoma (NTG). It has many clinical features that overlap with primary open angle glaucoma (POAG), yet there is a question of whether it has a different aetiology in which intraocular pressure plays less of a...
Diabetes mellitus is a systemic disease of great significance to optometrists. This review includes a brief history of the key discoveries in the understanding of diabetes from ancient times and a summary of the present knowledge of diabetes with respect to prevalence, epidemiology and major complications. The currently accepted classification of d...
This summary of low tension glaucoma discusses the difficulties of defining the disease, its prevalence and pathophysiology. The clinical presentation is contrasted with that of open angle glaucoma accompanied by high intraocular pressure in terms of differences in the optic nerve head appearance and visual field changes. The similarities of low te...
A patient who developed acute renal failure and subsequent bilateral non-arteritic anterior ischaemic optic neuropathy is described, The case was atypical in that the condition affected both eyes simultaneously, occurred in a young patient and was not associated with a recognised cause of renal failure or preexisting condition. Optic atrophy in the...
A case is presented in-which the detection of venous-stasis retinopathy in one eye led to investigation of the carotid circulation. There were no neurologic symptoms of carotid insufficiency, and noninvasive tests failed to reveal significant carotid pathology. Digital subtraction angiography and carotid angiography demonstrated a carotid plaque of...
Visual field screening conducted on indication was compared with routine visual field screening to determine the effectiveness of these strategies in identifying patients with normal and abnormal visual fields. The sample consisted of 1,500 consecutively presenting patients. Each patient was screened with the Friedmann Visual Field Analyser Mark II...
The clinical effect of detecting visual field loss was studied in 66 patients with visual field defects. Fifty-two percent of defects were the result of conditions which were themselves considered to be significant. Visual field results were considered to have made vital and important contributions to that diagnosis in 28% and 23% of cases, respect...
Central visual field screening of 2223 eyes without field defects was conducted with the Friedmann Visual Field Analyser Mark II. There was wide variation in the filter setting at which all stimuli were seen and in the working threshold relative to the recommended age filter. The ability to see all stimuli at settings higher than the age filter was...
The central visual fields of 44 optometric patients with known or suspected field defects were measured with the Friedmann Visual Field Analyser (FVA) and a 2-m tangent screen. The clinical correlation of visual field characteristics was at least adequate in more than 90% of eyes. Statistically significant correlations were also found between the a...
The general ophthalmological features of 18 patients with optic nerve head drusen are reported. Previous studies have reported that vascular anomalies such as increased branching of retinal blood vessels and vascular loops occur more frequently in association with drusen than in normal subjects. In this study, the number of major retinal blood vess...
A case is presented in which unilateral visible optic nerve head drusen and a contralateral visual acuity loss are associated with moderate hypermetropia and the use of oral contraceptives. Optic nerve drusen are known to be responsible for visual field losses, but a reduction in visual acuity is a rare finding. Extensive investigation of this pati...

... The tedious and uncertain nature of kinetic perimetry meant that it was not done as often as it should have been, despite the acknowledged importance of visual field loss to diagnosis and case management. 2 About three per cent of optometric patients have a visual field loss and indications for visual field examination are present in one in five patients. 3 Static perimetry began to take hold in the 1970s with the advent of semiautomated instruments, such as the Friedmann visual field analyser. ...
... 7 In clinical practice, standard automated perimetry (SAP) is a common method of assessing the visual field, [8][9][10] becoming increasingly popular in clinical practice and research settings since the 1970s and 1980s. 11 As visual field results can provide clues regarding the location of the anomaly along the visual pathway, it is an instrumental component of the ocular and neurological examination; [12][13][14][15][16][17] however, recent studies have highlighted a number of problems with visual field testing in clinical practice. For example, the frequency of performing visual field assessment for diseases such as glaucoma is often not carried out uniformly across eyecare practitioners. ...
... The association between hyperopia and the presence of ocular conditions such as strabismus, amblyopia has been proved for young children (Bruce & Santorelli, 2016), with reduced visual functions (distance Visual Acuity -VA), binocularity, near VA, reduced stereo acuity, and differences in convergence-to-accommodation (AC/A) ratio (Candy, Gray, Hohenbary, & Lyon, 2012;Fu et al., 2014). In adults, many ocular pathology were listed such as uveal effusion (Butler, 2004), pseudo-papilledema (Gutteridge, 1981), nonarteritic anterior ischemic optic neuropathy; AION ( (Pahor and Gracner, 2008), AION (Katz & Spencer, 1993), angle-closure glaucoma (Pitts & Jay, 1990;Sonmez & Ozcan, 2012;Zhang, Wang, Aung, Jonas, & Wang, 2015), and retinal vein occlusion (Albar, Nowilaty, & Ghazi, 2015). Also, hyperopic patients are shown to have a risk of glaucoma as compared to non-hyperopic patients (Wong, Klein, Klein, Knudtson, & Lee, 2001). ...
