About This Presentation

Description : Check out this medical PowerPoint presentation titled "Vision rehabilitation” by Angela West, MOT, OTR/L, CLVT, CAPS.

This medical PowerPoint presentation is about vision rehabilitation, a process of restoring functional ability and improving quality of life for individuals with vision loss or impairment. It includes a range of techniques, strategies, and therapies that can help individuals with vision loss to adapt to their new visual abilities and lead independent and fulfilling lives.

The goals of vision rehabilitation are to maximize a persons remaining vision, teach compensatory skills and techniques, and provide emotional support and resources for daily living. The process can involve a multidisciplinary team of professionals including ophthalmologists, optometrists, occupational therapists, rehabilitation teachers, orientation and mobility specialists, and low vision specialists.

Some of the techniques used in vision rehabilitation may include the use of optical and electronic aids, magnification devices, contrast-enhancing techniques, and adaptive equipment. Rehabilitation may also involve training in daily living skills such as cooking, cleaning, and personal care, as well as orientation and mobility training to help individuals navigate their environment safely and confidently.

Overall, vision rehabilitation can be a critical component in helping individuals with vision loss to achieve greater independence, improve their quality of life, and maintain their overall health and wellbeing.

Vision rehabilitation By Angela West, MOT, OTR/L, CLVT, CAPS Senior PasstheOT.com Tutor
Slide 2-

Quick anatomy/Physiology review Rods – responsible for night and black/white vision, peripheral vision Cones- responsible for color, fine detail, central vision (the MACULA has the highest concentration of cones) Scotoma – clinical term for “blind spot” in the visual fields of vision loss, blurriness, or distortion. Cataract – progressive opaqueness of the lens, resulting in blurred vision
Slide 3-

Visual terms Visual reception – how your brain RECEIVES visual stimuli/input Ocular motor functions: clarity, visual fields, eye muscle movements, convergence, divergence, accommodation These are also called “foundational visual skills” Diplopia? Nystagmus? Strabismus? Stereopsis? Visual perception – how your brain PROCESSES visual stimuli/input received Visual spatial relations Visual memory Figure ground Visual closure Visual motor integration Visual discrimination Form Constancy

Low vision versus legal blindness
Slide 6-

Macular degeneration Progressive blurring or visual loss of CENTRAL vision. MACULA – the “4 C’s of AMD” “Cones” “Central” “Color” “Clarity”
Slide 7-

Macular Degeneration Interventions Eccentric Viewing Techniques: A method of scanning peripheral visual fields to optimize vision using another point in the retina that has not been damaged by AMD – also called a psuedofovea training. Amsler Grid Training and Education Optical/Non Optical Device Training to compensate for impaired visual acuity Environmental modifications –optimize lighting, decreasing clutter, increasing contrast/high contrast Patient education on condition and its prognosis Community Resource Training/Support Groups Psychosocial impact/implications secondary to vision loss
Slide 8-

glaucoma Elevated intraocular pressure in the eye (IOP) due to decrease vitrous/aquous humor outflow - ultimately leading to progressive optic nerve damage and loss of peripheral vision. Described as “pinhole vision”. Generally affects both eyes, however one eye can have more advanced progressive loss than the other. Photophobia: “fear of lighting” – too much lighting can actually be painful for these folks
Slide 9-

Glaucoma interventions Medication management – eye drops Organized visual scanning patterns/visual sweep techniques to use central vision – LIGHTHOUSE strategies “Electronic magnification devices is often useful because it allows for increased visability of text by increasing contrast and brightness rather than size of the text” Safety during functional and community mobility Environmental modifications, especially with lighting because night vision is typically severely impaired with this population. (PHOTOPHOBIA!) Patient education on the condition and its prognosis Psychosocial impact/implications due to vision loss
Slide 10-

Diabetic retinopathy Often referred to as “Swiss cheese vision”/”Cow Patch” vision. Patients experience fluctuating, distorted vision with multiple blind spots presented in both central/peripheral vision due to diabetes. Symptoms also include difficulty with focusing/fixating on an object, loss of color vision, impaired contrast sensitivity, and reports of “floaters”. Also can experience photophobia What other considerations do we have to keep in mind for these folks??
Slide 11-

Diabetic Retinopathy interventions Amsler Grid Training Eccentric Viewing Special Tinted glasses to reduce glare and sharpen acuity Environmental Modifications (especially to address contrast sensitivity, tactile bump dots to account for severe vision loss) CCTV/Electronic Magnification Devices Community Resource Training Psychosocial Implications
Slide 12-

CVA related visual deficits Homonymous Hemianopsia Quadranopsia -- can result in visual apraxias What’s the difference between visual in/hemiattention and hemi neglect?

Question #1 What condition damages the optic nerve, causes increased pressure in the eye, and results in tunnel vision? A) Macular Degeneration B) Homonymous Hemianopsia C) Diabetic Retinopathy D) Glaucoma
Slide 16-

Question #2 A client has severe low vision secondary to diabetic retinopathy. The client wishes to independently cook family meals. Which client factor would be most important to assess prior to engaging the client in a cooking activity? ROM Visual Field function Tactile Discrimination Activity Tolerance
Slide 17-

Question #3 A middle aged client has macular degeneration resulting in moderate visual impairment. The client works as a data entry clerk and wants to continue working but is having difficulty seeing the computer screen. The OT will be adapting the client’s work computer with new software to improve accessibility. What computer feature of this new software would be most effective for this client? Braille keyboard compatibility Character enlargement Optical character recognition Voice-to-text speech
Slide 18-

Question #4 An OT completes an evaluation with a 6-year old child and the results indicate that the child has deficits in visual discrimination affecting handwriting. Based on this information, what strategy might the therapist include in the intervention plan to best address visual discrimination? Multisensory writing techniques to reinforce correct letter formation and to emphasize the differences between similar letters Dot-to-dot and maze worksheets Cue the student to use his fingers to move the pencil while completing writing tasks Practice writing letters in sand with shaving cream
Slide 19-

Question #5 The director of rehabilitation asks a newly hired OTR® to provide occlusion to a client who is experiencing diplopia to enable the client to more fully participate in rehabilitation. Which action should the OTR take FIRST in response to this request? Provide occlusion to the client and notify the director that the task has been completed Refuse the director’s request, because occlusion is inappropriate for an OTR to provide Explain to the director that occlusion can be provided only under the direction of a physician or CLVT specialist Refer the request to another OTR with more experience in oculomotor function
Slide 20-

Question #6 An outpatient occupational therapist is developing an intervention plan for a client with primary open angle glaucoma. What would be the best option to include in the intervention plan for this client? Environmental control unit operations training Use of bold-lined paper and bold pens for writing tasks Large-print labels on commonly used kitchen items Training in rotation of head and trunk to scan environment during functional mobility activity
Slide 21-

Question #7 After stroke, a client has difficulty orienting to relevant visual stimuli on the left side, including food on the plate and grooming items on the counter. The client completes feeding and grooming tasks swiftly and with reduced effort. What symptom would the OTR® report in the client’s evaluation results? Hemispatial visual neglect Visual discrimination deficit Visual field deficit Motor neglect
Slide 22-

Question #8 A client reports diplopia and demonstrates asymmetrical pupil sizes and a droopy eyelid. What would be MOST appropriate for the OTR® to evaluate? Oculomotor function Visual acuity Contrast sensitivity Visual fields
Slide 23-

Question #9 An OTR is working with a client who has difficulties with visual skills as a results of damage to the central nervous system. Which visual skill is related to CNS damage? Visual memory Stereopsis Figure ground Kinesthesia
Slide 24-

Question #10 An older adult client with a history of falls and glaucoma is referred to occupational therapy for evaluation and intervention. Which strategy should the OTR® teach the client to compensate for impaired vision due to glaucoma? Use a colorful, patterned tablecloth. Place dinner plate to the left of midline. Rotate head to choose clothing from a closet. Pour coffee into a dark colored mug.
Slide 25-

Question #12 When working on home modifications with a patient who has low vision, what is the MOST APPROPRIATE home modification to the patient’s bedroom to enhance the patient’s independence when dressing? Increase the distance between the patient and the object Increase glare from sunlight Optimize lighting Decrease contrast sensitivity with nightstand items
