Clinical examination

Bilateral Eye Examination SimulatorCompare combinations of right- and left-eye findings and bilateral responses on a virtual patient.Explore the simulator
Eye Exam SimulatorA virtual patient with 43 conditions: penlight pupil exam and RAPD, cover tests, Hirschberg and Krimsky, ductions and versions, cranial nerve palsies, INO, gaze palsies and nystagmus.Explore the simulator
Cover Test SimulatorPractise cover–uncover and alternate cover testing on a virtual patient. Compare tropias and phorias, observe refixation and explore prism neutralization.Explore the simulator
Hirschberg & Krimsky SimulatorStudy corneal light reflex displacement, compare simulated strabismus and angle kappa, and explore prism-based Krimsky testing in the eye exam simulator.Explore the simulator
RAPD & Swinging Flashlight Test SimulatorPractise the swinging flashlight test and observe a relative afferent pupillary defect on a virtual patient. Compare right- and left-eye responses with the normal examination.Explore the simulator
Nystagmus SimulatorExplore the nystagmus conditions in Pupilla’s eye exam simulator. Observe waveform, direction and gaze dependence, then connect your observations to the learning guide.Explore the simulator

Refraction & optics

Ophthalmic Optics SimulatorConnect optical foundations with interactive practice and an optics assessment.Explore the simulator
Retinoscopy SimulatorRead with and against motion, find the principal meridians and neutralize the reflex for myopia, hyperopia and astigmatism.Explore the simulator
Refraction SimulatorChange axial length, corneal curvature and astigmatism, then correct them with sphere, cylinder and axis trial lenses and watch Sturm's conoid collapse onto the retina.Explore the simulator
Vision Simulator: Refractive Blur & Visual AcuityApply a prescription and watch an eye chart, a page of text and a night street blur the way that refractive error really blurs them, with a live logMAR and Snellen readout.Explore the simulator
Lensometer SimulatorRead a finished spectacle lens on a manual lensometer: close the doubled American Cross mires on the power drum, find the axis on the unbroken thin line, take the cylinder as the difference of two readings, and watch Prentice's Rule put prism on the reticle rings.Explore the simulator

Anatomy & eye movements

3D Eye Movement SimulatorStudy binocular gaze, extraocular muscle actions and coordination of eye movements.Explore the simulator
3D Extraocular Muscle SimulatorContract each extraocular muscle, see its action in the nine gaze positions and follow Hering's and Sherrington's laws.Explore the simulator

Imaging & visual pathways

OCT Simulator & Interpretation PracticeExplore retinal and optic nerve head scans, learn OCT interpretation and practise with cases.Explore the simulator
Visual Pathway SimulatorPlace a lesion anywhere from the optic nerve to the occipital cortex and see the visual field defect, with lessons and a case quiz.Explore the simulator
