The Indian operation of couching for cataract

Against the vaidyans’ figures we may place the statistics of the
Madras Hospital, even so long ago as 1903, and before a rigid system
of antisepsis had been introduced. Recoveries numbered 96 per cent.,
poor results 2 per cent., and failures 2 per cent. These figures would
indicate that the coucher was losing 60 per cent. more eyes than
the hospital did even then. If the vast number of eyes submitted to
couching be taken into account, this 60 per cent. of avoidable loss
totals up to a staggering figure. Nor must we disregard the fact that,
even amongst the successes, the average vision obtained is greatly in
favour of the Western surgeon.
The table showing the causes of failure will repay a careful study.
The figure for iritis and iridocyclitis comes to 35·76 per cent.
of the _total_ number of cases; glaucoma accounts for 11·05 per
cent., imperfect dislocation of the lens for 8·94 per cent., retinal
detachment for 3·53 per cent., optic atrophy (including one case of
optic neuritis supervening as a septic complication of the operation)
for 2·59 per cent., retinitis pigmentosa and retinitis punctata
albescens for 0·49 per cent., retinochoroiditis for 1·41 per cent.,
vitreous opacities (admittedly a very vague term) for 1·18 per cent.,
and failure due to operation on a congenitally imperfect eye for 0·23
per cent.; 3·53 per cent. are, unfortunately, unaccounted for owing to
deficiencies in the notes.
In the great majority of cases ruined by iridocyclitis the inflammation
made its appearance within a few days after operation; but there were
instances in which this complication was delayed for a long period.
Our notes show three cases in which it came on from one and a half to
three years after operation, one case after seven years, and one after
ten years. There are also a few doubtful cases in which a history of
three or four months of useful vision preceded the inflammatory attack.
In one case at least, sympathetic ophthalmia would appear to have
destroyed the other eye two years after operation.
Similarly, it was found in most cases of glaucoma that the access
of high tension came on within a few days of operation. There were
six exceptions to this rule, three commencing from two to ten months
after the couching, one five years, one six years, and one fourteen
years after. From a clinical point of view, the cause of the onset
of glaucoma in these cases is obscure. Many of them appear to be
associated with iridocyclitis, but we must leave this matter for the
present. We shall have occasion to deal with it much more fully under
the heading of pathology.
