n of cystoid scars or minute fistulae, rather
than as a result of the removal of a portion of the iris periphery.

The best brief tabulation of the results obtained by iridectomy, in
glaucoma, is to be found in Weeks' textbook on _Diseases of the Eye_,
page 417: "Sulzer reports as follows: Acute glaucoma, 149 cases;
improved, 72.5 per cent; serviceable vision preserved, 11.3 per cent;
vision impaired at once, 4.08 per cent; very little vision, 12.12 per
cent.

"Zentmeyer and Posey: In simple glaucoma central vision increased in 60
per cent; remained the same in 20 per cent; diminished in 20 per cent.

"Wygodski: Inflammatory glaucoma, 37 cases; improvement, 76 per cent;
unimproved, 5 per cent; deterioration, 19 per cent. Sub-acute (chronic
inflammatory), 147 cases; improvement 10 per cent; unimproved (condition
the same as before iridectomy), 40 per cent; deterioration, 30 per cent;
blindness, 20 per cent. Cases operated on at an early stage gave 85 per
cent of good results. Simple glaucoma, 104 cases; improvement, O.96 per
cent; condition as before, 10.5 per cent; deterioration, 52 per cent;
amaurosis, 36.5 per cent.

"Hahnloser and Sidler: One hundred seventy-two eyes observed not less
than ten years after operation; acute inflammatory, 31 eyes; good
results, 64 per cent; relatively good, 13 per cent; blind 23 per cent;
chronic inflammatory, 37 eyes; good result, 29.9 per cent; relatively
good, 27 per cent; blind, 43 per cent; simple glaucoma, 76 eyes; good
results, 42 per cent; relatively good, 28.9 per cent; blind, 28.9 per
cent."

As far as the _Lagrange procedure_ is concerned, you will remember that
after eserinization an oblique incision is made through the sclera by
means of a narrow Graefe knife and a large conjunctival flap secured.
This is obtained by making a peripheral section of the sclero-corneal
margin with the knife and, as soon as the edge of the knife reaches the
upper limit of the anterior chamber, it is turned backward and brought
out through the sclera obliquely. The conjunctival flap thus formed is
turned back over the cornea, and the fragment of sclera that is left
attached to the cornea is removed by means of a fine pair of delicate
curved scissors. Following this an iridectomy is performed. The
conjunctival flap is now replaced and a bandage applied.

This operation opens a large filtration passage for the intra-ocular
fluids and the prompt healing of the wound with its mucous covering
