BACKGROUND We have developed a binocular perimetry technique for the quantitative assessment of retinal photoreceptor displacement and metamorphopsia. OBJECTIVE To study the direction and amplitude of retinal photoreceptor displacement in eyes with idiopathic macular holes using our binocular perimetry technique. SUBJECTS Five healthy control subjects and 10 patients with unilateral stage 3...

PURPOSE To evaluate the degree of metamorphopsia in 42 patients before and 6 months after vitrectomy for idiopathic unilateral macular hole. METHODS Semicircular test and reference stimuli of variable diameters were applied in a binocular test that measured interocular size disparity in patients with unilateral macular hole. The test was applied 1 day before surgery and repeated after 6 month...

A 40-year-old woman presented with decreased vision and metamorphopsia in her left eye since 3 weeks ago. She had no history of systemic disorders and drug history was unremarkable. Best corrected visual acuity (BCVA) was 10/10 and 8/10 in her right and left eyes, respectively and afferent pupillary defect was negative. Anterior segment examination and intraocular pressure were normal. On fundu...

We examined 4 patients in the past 6 years who were first seen at our institution because of metamorphopsia and who were eventually diagnosed as having idiopathic intracranial hypertension (IIH). Idiopathic intracranial hypertension is a condition of elevated intracranial pressure that occurs primarily in young women. Neuroimaging findings and cerebrospinal fluid (CSF) indices are normal. Its c...
