Epithelial ulceration Stromal suppuration/ abscess Diffuse epithelial oedema Stromal infiltrate Endothelial plaque Hypopyon

Answer 13

``` istory Contact lens Trauma Previous surgery Pre-existing ocular diseases Urban/ rural Topical and systemic medication Examination ``` we need to identify pathogen and its sensitivity to antibiotics we need corneal scrapings- Green needle Surgical blade Sterile spatula admit to hosp- if no bacteria iddentified- then give broad spectrum antibody

Answer 14

``` Blunting of the perimeter of the stromal infiltrate – ↓ density of the stromal infiltrate – ↓ stromal oedema and endothelial inflammatory plaque – ↓ anterior chamber inflammation – Reepithelialization of defect – Improvement in painful symptoms No response to therapy Compliance/?????
