    important clinical fact, inasmuch as it usually happens at a time—two to eight days after operation—when eyes are rarely examined ophthalmoscopically, and passes away before the time comes for testing sight, and never permanently affects the vision. It seems to be due to the penetration of aqueous into the suprachoroidal space through a small tear at the attach- ment of the ciliary body, and is marked clinically by failure of the anterior chamber to properly refill, or by its emptying after once refilling. Ervthropsia—red vision—has been complained of extremely rarely by any of our patients, possibly because they are warned to wear dark glasses for some time after discharge from hos- pital. For a good account of it see Norris and Oliver’s ‘ System,’ iv. 394. Indifferent and Bad Results, on discharge from hospital, among 1,172 extractions, from February i, 1901, to March 31, 1903, the period under review on pp. 53-55 ; collected to give some idea of the complications before and after operation that have interfered with vision : 2, V = nil. I, Patient 22 years; over-ripe cataract, possibly congenital. Absence of vision unaccounted for, * I, suppuration. I, V = light only. Acute traumatic glaucomatous irido-cyclitis at the time of operation. 16, V = moving bodies only— 4, much cortex left. 1, lens lost in vitreous. 2, disease of vitreous, soft eyeball before operation. I, nystagmus, congenital cataract. 1, old secondary glaucoma, posterior synechim. 2, probable detachment of retina after vitreous loss. 5, glaucoma before operation ; much cortex left in two cases. ^ The cases unaccounted for are explained thus; Though I saw them all before dischai'ge, the vision was not tested till after I had given permission for their discharge, and hence the oppor- tunity for investigating the cause of visual defect was sometimes lost.
