Question

Answer the following:

• Compare sensor neural and conductive hearing loss as for: causes and diagnosis using tuning fork and which patients get benefit of hearing aids

• Compare cataract vs glaucoma as regards: causes, methods of diagnosis

• Explain how you would record a patient’s test results for the right eye at the 20/30 line,

and missing one letter

Answer 1

1-Conductive hearing loss short-duration hearing loss it can be treated usually mild and moderate hearing deficiency ,rinne test is negative ,blockage in outer ear preventing conduction of sound in the inner ear ,absolute bone conduction is normal

In sensory neurone hearing loss the permanent hearing loss cannot be treated bi managed by hearing AIDS absence or damage sensory hair cell in the middle ear rinne test is positive can be mild moderate and severe ,absolute bone conduction

causes of conductive hearing loss fluid allergies, foreign objects, ruptured eardrum or imbacted ear wax

causes of sensory neurone deficit including ageing or toxicity ,loud noise ,blast or explosion any tumors

Diagnosis of hearing loss including physical examination general screening test app based hearing test tuning fork test audiometry test

Hearing aid is benefited in conductive hearing loss in sensory neurone hearing loss earring AIDS will not be effective

2-glaucoma is a increased I pressure that damage the optic nerve,glaucoma can lead to permanent blindness, glaucoma usually has no symptoms, strong connection with family history, glaucoma considered as a disease, typically treated with eye drops but laser surgery can be required, . Early diagnosis is important because once damage happen it cannot be reverted

Cataract are clouding of the lens of the eye,Cataract rairely lead to blindness, it is almost treatable patient has cataract it is always symptomatic usually cloudy or blurred vision everyone will get cataract if they live long aging is the one factor.in early stage of cataract vishay usually can be improved with changing glass prescription

causes of glaucoma including build-up of pressure in the eye when fluid is unable to drain properly this pressure damages the that connect to the brain optic we've, age increased age is one factor ethnicity family history other medical conditions like diabetes

Causes of cataract including aging diabetic, use of steroid any surgery or eye injury, radiation treatment ,spending lot of time in the sun without eye protection

Diagnosis of cataract including medical history symptoms symptoms assessment physical examination examination visual activated test slit lamp examination veginal examination of the method used to diagnose cataract

Diagnosis of glaucoma including eye examination , history taking ,tonometry to assess in intraocular pressure ,testing for optic nerve damage checking the areas of visual loss measuring the corneal thickness inspecting the drainage angle

3-20/ 30 is test score test is a distance visual testing for example if the patient is able to read three letters in a six letters that we consider as 20/30 then then ask the patient to read the next line that is smaller line it is called 20/25 if the patient couldn't see any of the letter on 20/25 line you would record the patient will select it as 2030
