Delayed re-formation of anterior chamber after trephine operations.

Penetrating corneal graft; orientation of the initial penetration of the trephine into the host cornea.

DURING the operation of perforating graft of the cornea, the trephine in the great majority of cases enters the anterior chamber in only a portion of its circumference, the remaining circumference of the graft being completed with scissors. The author has noticed, both in operations performed personally and in those performed by others, that the portion of the circumference of the trephine whic...

Miotics or mydriatics for atony of the ciliary muscle with delayed re-formation of anterior chamber after cataract extraction with complete iridectomy.

Failure of filtration operations in the African.

Filtration operations in Negroes and in other heavily-pigmented races have earned a bad reputation for a high rate of failure, but it is difficult to estimate the extent of this failure because it is difficult if not impossible to achieve an adequate follow-up in these cases (McNair, I95I; Welsh, I969). Iliff (I944) reported a success rate of 23 per cent. with trephine operations and of 50 per ...

Equatorial cataract after corneoscleral trephining.

THE occurrence of cataract in association with glaucoma presents a therapeutic problem of some magnitude which has attracted a good deal of attention in recent years (Samuels, 1947; Sourdille, 1950; Chandler, 1949;, Fran9ois, 1947; Williamson-Noble, 1953). The difficulties of treatment are not made less by the uncertainty which still exists as to the role played by the glaucomatous process and ...

Gonioscopic changes after glaucoma surgery.

Trantas (I 907) made the first recorded observations on the angle of the anterior chamber, which he viewed through an ophthalmoscope while indenting the sclera at the limbus on the opposite side. He introduced the term gonioscopy, and found that a view could be obtained using either direct or indirect ophthalmoscopy. A few years later the first attempt to view the angle through a contact lens w...
