PURPOSE Functional monocular hemianopia is an extremely rare condition, for which measurement of hemifield visual evoked potentials (VEPs) has not been previously described. METHODS A 14-year-old boy with functional monocular hemianopia was followed up with Goldmann perimetry and measurement of hemifield and full-field VEPs. RESULTS The patient had a history of monocular temporal hemianopia...

A 22-year-old Malay female presented with left eye floaters for 2 weeks, associated with temporal visual field defect and metamorphopsia for 3 days. She has a guinea pig and a hedgehog at home, but denied being bitten or scratched by them. Her visual acuity at presentation was 6/12 on the left eye and 6/6 on the right eye. Her left eye relative afferent pupillary defect was barely positive with...

The purpose of this article is to report a case of nonarteritic anterior ischemic optic neuropathy (NAION) after uneventful cataract surgery. A 53-year-old Filipina underwent cataract surgery. She had a small optic disc with cup-to-disc ratio of 0.2 in the left eye and 0.3 in the right eye. On the first postoperative day, the uncorrected visual acuity (UCVA) was 20/20, with an intraocular press...

PURPOSE This study investigated the correlation between the relative afferent pupillary defect (RAPD) and retinal nerve fiber layer thickness (RNFLT) in optic neuropathy. METHODS RAPD assessment was performed using a log unit neutral density filter bar. Spectral domain optical coherence tomography RTVue-100 (Optovue) was used to examine the subjects. The optic nerve head pattern (ONH) was sub...

A healthy 28-year-old lady, para 1, presented to the emergency department with persistent frontal headache, nausea, and vomiting following an cesarean section four days ago. She experienced difficulties six failed attempts of spinal anesthesia intrapartum before conversion general anesthesia. 25-gauge Whitacre needle was utilized for administering under a sitting position. The anesthetist notic...

purpose: to report tonic pupil in a patient with ocular siderosis. case report: a 12-year-old male patient presented with over-sized right pupil from two weeks before. visual acuity (va) was 10/10 in both eyes without afferent pupillary defect. anisocoria was present with the right and left pupils, measuring 5 and 3 mm in diameter, respectively. anisocoria was greater in bright light and there ...

purpose: to determine factors that affect and predict final visual acuity, retinal attachment, and ocular survival after open-globe injuries. methods: one-hundred sixteen eyes with open globe injuries were evaluated longitudinally from september 2001to february 2004. age, sex, involved eye, best corrected visual acuity (bcva), afferent pupillary defect (apd), size and location of laceration, ca...

PURPOSE We examined the relationship between relative afferent pupillary defects (RAPDs) and macular structural damage measured by macular thickness and macular ganglion cell-inner plexiform layer (mGCIPL) thickness in patients with glaucoma. METHODS A cross-sectional study was done of 106 glaucoma patients and 85 healthy individuals from the Diagnostic Innovations in Glaucoma Study. All subj...

The pupils of 15 patients with myotonic dystrophy tvere examined with the electronic pupillograph of Loioenstein and Loeioenfeld. They were found to have round, equal, miotic pupils which reacted sluggishly to light and to near vision. The studies showed no defect of the sympathetic pathways. Pupillary fatigue was comparable to the normal. Various locations for a defect causing this combination...
