INTRODUCTION Fibrous dysplasia is a benign tumour of the bones and is a disease of unknown aetiology. This report discusses a case of proptosis and visual deterioration with associated bony mass involving the right orbit. CASE PRESENTATION A 32-year-old Nigerian man of Yoruba ethnic origin presented to the eye clinic of our hospital with right-eye proptosis and visual deterioration of 7-year ...

PURPOSE To evaluate the validity of different methods of relative afferent pupillary defect (RAPD) detection and assess the usefulness of detecting an RAPD in glaucoma patients. METHODS For this prospective observational study, we enrolled 70 of 153 consecutive glaucoma patients coming for examination. Exclusion criteria were cloudy corneas, recent surgery, fixed pupils, and other diseases pr...

PURPOSE To report clinical characteristics of optic neuritis (ON) in Koreans >50 years of age. METHODS A retrospective chart review was performed on patients with ON between January 2000 and December 2009. We obtained the best-corrected visual acuity (BCVA), Goldmann perimetry, relative afferent pupillary defect (RAPD), and color function tests as well as brain magnetic resonance imaging (MRI...

Purpose. Case report describing an eight-month-old infant presenting with intermittent esotropia and irritability who was found to have malignant (grade 4) hypertensive retinopathy and mid-aortic syndrome. Methods. Visual acuity was 6/140 in the right eye and not recordable in the left eye. Blood pressure was as high as 230/120 mmHg. Fundoscopy revealed bilateral optic disc swelling, macular st...

A 69-year old man presented to us with decreased vision in his right eye and a relative afferent pupillary defect. Under the presumption that he was suffering from retrobulbar optic neuritis or ischemic optic neuropathy, visual field tests were performed, revealing the presence of a junctional scotoma. Imaging studies revealed tumorous lesions extending from the sphenoid sinus at the right supe...

A 30‐year‐old man noticed acute visual loss in his left eye following explosion of a vehicle tire tube while inflating. On presentation, Snellen visual acuity (VA) was 20/20 in the right eye and 2 meters counting fingers in the left eye. Relative afferent pupillary defect was negative. A small area of temporal conjunctival hemorrhage, anterior chamber red blood cells (1+), and inferotemporal ir...

A 4-year-old girl with normal development presented with progressive ocular deviation of 3 years’ duration; past medical and ocular history was unremarkable. Upon presentation, cycloplegic refraction revealed refractive error of +1.00 -0.50×180 and -14.00 in the right and left eyes. Visual acuity was 20/20 and 20/400 in the right and left eyes with optical correction of plano and -14.00, respec...

SECTION 1 A 42-year-old man underwent brain MRI at a local health facility for severe headache and was found to have a pituitary adenoma. Two days later, he presented to the emergency department of our hospital with high fever and sudden-onset coma. The patient had a history of intermittent moderate headache in the recent 8 months. No medical history of vascular risk factors was identified. On ...

PURPOSE To compare the anatomical and visual outcomes of three different scleral buckling techniques and to explore the effect of cryotherapy and subretinal fluid drainage (SRFD) on outcomes of surgery. METHODS This retrospective study was performed on 111 eyes of 109 patients undergoing scleral buckling for rhegmatogenous retinal detachments (RRDs) by a single surgeon. Pre-, intra- and posto...

The neuro-ophthalmologic examination provides an enormous amount of information about the 40% of fibers that provide afferent and efferent limbs of the visual, pupillary, and ocular motor pathways. A few tools and the correct testing approach will maximize the value of this examination. This chapter provides step-by-step examination methods and points out some of the common errors that are made.
