This study suggests that patient satisfaction with endoscopic endonasal non-laser DCR for primary or revision DCR surgery is comparable to that with the external-DCR technique since there was no significant difference in patient satisfaction between the two groups of patients. Patient perception of their symptomatic improvement was lower (though not statistically significant) in relation to the final clinical assessment of the outcome of both primary and revision EN-DCR.

p. 359) concerning ammonia burns and the eye. Recently a patient was seen two hours after a jewellery robbery, having had ammonia thrown in her eyes. One eye showed loss of corneal epithelium and conjunctival injection. The other showed gross conjunctival injection, loss of corneal epithelium, stromal haze, and folds in Descemet's membrane. There was much fibrinous material in the anterior chamber, iris atrophy, a vertical oval-shaped pupil, and subcapsular lens opacities. The intraocular pressure was normal in both eyes and has never subsequently been raised. The lens opacities later became similar to those of glaukomflecken. At present, five months after the accident, the patient has developed band-shaped corneal degeneration in the more severely affected eye and heterochromia of the iris, but the lens opacities have not progressed.-I am, etc.
