Blepharitis is the result of an eyelash follicle infection. Viral or bacterial conjunctivitis is not easily spread. In glaucoma, fluid pressure builds up in the eye. There is a loss of the vision in the center of the eye with  retinal detachment. Presbyopia is related to aging. Visual defects are the most common eye disorders  treated by ophthalmologists.ANSWER:TTTTFFFA stymacular degenerationOphthalmic ExamsOphthalmoscope TestsVisual fieldsConvergence of the eyesGlaucoma – tonometer Ophthalmology ExamsSlit lamp Refraction examTypes of Vision Screening TestsIncludes tests forThe ability to see clearlyThe ability to distinguish shadesof grey and colorsScreeningSnellen chartJaegar chartIshihara bookTypes of Vision Screening Tests (cont.)Near VisionHyperopia PresbyopiaContrast SensitivityShades of grayCataracts / retinal problemsColor visionColor-blindnessRetina / optic nerve problems(Reprinted with permission of Richmond Products, Inc.)Apply Your KnowledgeMatch the following: used to view the inner eye measures intraocular pressure used to examine the anterior eye verifies the need for corrective  lenses Snellen chart Jaegar chart Ishihara book Refraction examOtoscopeDistance visual acuityColor-blindnessTonometer Near visionSlit lampBANSWER:EGACFDCorrect!Ophthalmologic Procedures and TreatmentsMinor injury or infection – lasting consequencesMedical assistantProper techniquePatient education Routine careWarning signs Use of protectiveequipmentAdministering Medications to the EyePurposesAssist patients in eye testsReduces pressure in the eyeRelieves eye painTreats infectionsMedical assistantDispense eye medicationPatient instructionsAdministering Medications to the Eye (cont.)Eye irrigationRemove foreign materialsRelieve discomfortUse sterile solutionApply Your KnowledgeWhen administering eye medications, you should avoid touching the tip of the dropper or tube to the eye.
