Eyes are tested in following steps.
» Vision Testing
- Acuity of vision is tested with or without correction for distance at 6meters or 20 feet and near at 33cms. Refractive errors are diagnosed manually with Retinoscopes and Automatically by Autosrefractors. Corneal astigmatism id diagnosed by Keratometers.
- Field of vision is tested by Kinetic method, manually with Lister perimeter and by static technique on Octopus autoperimeter.
- Colour Vision Tested on Ishihara charts.
» Pupillary Reaction testing is done in a dark room with Slit-lamp Magnification with narrow slit beam from various directions
» Anterior Segment examination is done under step magnification under Slit-Lamp to detect pathologies in Lids, Conjunctiva, Cornea, Anterior Chamber, Lens and Iris. Documentation of cases is done by Digital Video Recording.
» Intraocular pressure is measured by Non-Contact tonometer. For special situations, Tonopen, Slit-Lamp applanation and Schiotz tonometers are used.
» Central Corneal thickness is measured by Pachymeter.
» Retinal examination is done in detail with Indirect Ophthalmoscopy with Video documentation of special cases. Digital image documentation and Fundus Fluorescein angiography is done on Zeiss Visucam Camera.
» Binocular vision is tested on Synaptophore.
