Chapter 22: Visual Problems: Assessment & Management

Age-related changes affecting vision assessment are thoroughly examined, including presbyopia development, cataract formation, arcus senilis appearance, and diminished tear production in older adults. Assessment techniques encompass both subjective data collection focusing on systemic diseases like diabetes and hypertension, medication histories including corticosteroids and antimalarials, and comprehensive functional health pattern evaluation, alongside objective examination methods using Snellen charts, confrontation testing, tonometry, and ophthalmoscopic evaluation. Diagnostic procedures covered include Amsler grid testing, fluorescein angiography, visual field perimetry, and optical coherence tomography for detailed retinal imaging. The chapter extensively addresses refractive errors including myopia, hyperopia, astigmatism, and presbyopia, with correction methods ranging from traditional eyewear to laser procedures like LASIK and photorefractive keratectomy. Major pathological conditions receive detailed coverage, including diabetic and hypertensive retinopathy with their characteristic microaneurysms and hemorrhages, age-related macular degeneration in both dry and wet forms with anti-VEGF therapy protocols, various forms of glaucoma including primary open-angle and acute closure types with their distinct management approaches, cataract formation requiring phacoemulsification surgery, and retinal detachment as an ocular emergency requiring immediate intervention through photocoagulation, scleral buckling, or vitrectomy procedures. Nursing management principles emphasize prevention strategies, comprehensive patient education, perioperative care coordination, and psychosocial support for patients experiencing vision loss.
