A 79-year-old male remarks on his first visit that he has noticed a gradual decrease in vision in both his eyes since last year. His old medical record has not yet arrived at your office. He states that since he moved from Florida a year ago, he has not had an eye examination and does not yet know an ophthalmologist. He is having difficulty carrying on his activities of daily living that involve his sight. He states that he cannot recognize people at some distance until they come quite close and he is often frightened by his perception of strangers speaking to him. Watching television and reading are becoming increasingly difficult for him. He states that glare is a problem and notes that a few times he almost tripped over something on the floor. He still drives his car in the local community. He asks if you think he may have a cataract. He says his wife had two cataracts in the past and he remembers her complaining of vision problems which have now resolved.
Vital Signs: BP 128/84; HR 82; RR 18; BMI 24.
Chief Complaint: Decrease in my vision; glare is very bothersome!

Submission Instructions:
- Post should be at least 500 words, formatted and cited in current APA style with support from at least 2 academic sources.
Subjective Data:
- Past medical history: In addition to the patient’s current concern, it is essential to inquire about any previous medical conditions, surgeries, or chronic illnesses that might be relevant to his vision problems. Information about diabetes, hypertension, and any other ocular conditions should be gathered.
- Medications and allergies: Knowing the patient’s current medications and any known allergies will help identify potential drug-related causes of vision changes or rule out adverse drug reactions.
- Social history: Understanding the patient’s lifestyle, occupation, and habits can provide insight into potential environmental factors that could be contributing to his vision problems. For example, prolonged exposure to sunlight without proper eye protection in Florida might be a relevant factor.
- Family history: Further details about the patient’s family history of eye diseases, particularly cataracts and other hereditary eye conditions, can help in the diagnostic process.
Objective Data:
- Visual acuity assessment: Measuring visual acuity using an eye chart will help quantify the extent of the patient’s vision loss.
- Slit-lamp examination: This will allow the ophthalmologist to examine the structures of the eyes, including the lenses, for any abnormalities like cataracts.
- Intraocular pressure measurement: Elevated intraocular pressure could indicate conditions like glaucoma, which can sometimes be associated with cataracts.
- Fundus examination: This will help assess the health of the retina and optic nerve, ruling out any other potential causes of vision loss.
Differential Diagnoses:
- Cataracts: Given the patient’s age, symptoms, and family history, cataracts are a likely primary consideration.
- Age-related macular degeneration (AMD): This is another common cause of vision loss in older adults and should be ruled out.
- Glaucoma: Elevated intraocular pressure and potential peripheral vision loss may be relevant, although it does not explain all of the patient’s symptoms.
- Diabetic retinopathy: Since the patient’s medical history is not yet available, it is important to consider diabetes as a possible cause of his vision problems.
Laboratory Tests:
- Blood glucose levels: To check for diabetes or assess glycemic control if diabetes is already known.
- Complete blood count (CBC): To rule out anemia or other systemic conditions that might affect vision.
- Electrolyte panel and renal function tests: These can help evaluate the patient’s overall health, especially if surgery or certain medications are being considered.
Radiological Examinations and Additional Diagnostic Studies:
- Optical Coherence Tomography (OCT): This non-invasive imaging test can provide detailed images of the retina, helping to diagnose conditions like AMD or diabetic retinopathy.
- Visual field testing: This test can detect peripheral vision loss, which may be present in conditions like glaucoma.
Treatment and Prescription Information: If the diagnosis confirms cataracts as the primary cause of the patient’s vision loss, the most appropriate treatment would be cataract surgery. The patient should be informed that cataract surgery is generally safe and effective. However, it is essential to discuss potential complications, such as infection, inflammation, or rare cases of retinal detachment or posterior capsular opacification (PCO) following surgery.
Additional Laboratory Tests: Depending on the initial findings and the patient’s medical history, further tests like lipid profile, liver function tests, or other specialized tests might be considered.
Patient Teaching: The patient should be educated about the importance of regular eye examinations, especially given his age and the presence of cataracts. He should also be advised about managing glare by wearing sunglasses, using anti-glare coatings on glasses, and optimizing lighting conditions at home. Furthermore, he needs to be informed about driving restrictions and guidelines related to his vision impairment.
Consultation: A referral to an ophthalmologist for a comprehensive evaluation and confirmation of the diagnosis would be appropriate, especially if the patient requires cataract surgery or if there are any other complex issues affecting his vision. The ophthalmologist can provide specialized care and treatment options based on the patient’s individual needs.
