Phacolytic glaucoma to as a ‘slit lamp examination’ of phacolytic glaucoma allows for specific identification of microcystic corneal edema and the presence of macrophages, white material (dotted with patches within the inside capsule of the lens) and intense flare and iridescent or hyper-refringent particles specific to phacolytic glaucoma. The time period which symptoms have been affecting the patient should be obtained as experiencing symptoms for a period longer than 5 days may result in further issues such as glaucomatous disc damage or poorer prognosis. Additionally, previous cataract or trauma surgery which have been conducted must be accounted for so that an accurate
