2.) What are the diagnostic procedures that could help you in your management? History and PE • thorough history • careful physical examination must be performed • entire body habitus is checked for abnormalities that may point out systemic illnesses Ocular Examination • Visual acuity for both near and far distances (Snellen’s Chart) • Glare- brightly lit room Swinging Flashlight Test • detects for a Marcus Gunn pupil or a relative afferent pupillary defect (RAPD) • indicative of optic nerve lesions or diffuse macular involvement. • RAPD + Cataract= very guarded visual prognosis after cataract extraction Ocular Motility • long-standing ptosis since childhood may have occlusion amblyopia – decreased visual acuity rather than the cataract • Checking all directions- to rule out any other causes for the patient's visual symptoms Slit Lamp Examination • should not only concentrate on evaluating the lens opacity but the other ocular structures as well (eg, conjunctiva, cornea, iris, anterior chamber) • Corneal thickness and the presence of corneal opacities • lens noted meticulously before and after pupillary dilation • Nuclear size and Brunescence as indicators of cataract density can be determined prior to phacoemulsification surgery. • lens position and integrity of the zonular fibers also should be checked – lens subluxation may indicate previous eye trauma, metabolic disorders, or hypermature cataracts. – Dilated fundus examination is recommended as part of the ocular examination for both unilateral cataract cases and bilateral cataract cases.
