Page 209 - A' and B' are then knotted firmly at C. The end bearing the needle is then entered at D, and passed through conjunctiva, capsule and muscle, and carried beneath the lower blade of the Prince's forceps nearly to the corneal margin. The needle is here passed through the tough circumcorneal fibrous tissue and brought out at G.
Page 208 - B. The bight of the thread thus encloses about the lower fourth of the width of the muscle, together with its tendinous expansions and capsule and conjunctiva. The other needle is similarly entered at A', passed through conjunctiva, capsule and muscle, and brought out at the under side of the muscle.
Page 207 - The conjunctiva and capsule usually then retract as shown in the diagram. If they do not they are pushed back, so as to expose the insertion of the tendon. The female blade of a Prince's advancement forceps is now passed under the tendon, after the manner of a tenotomy hook, the male blade being superficial to the conjunctiva. The forceps is now closed, so that tendon, capsule of Tenon, and conjunctiva are all firmly clamped together, with their relations...
Page 13 - In looking at any solid object, such as a pillar, for instance, the right eye will see more of the right side of the object and the left eye more of the left side.
Page 124 - The two halves of the instrument can be brought together to suit a convergence of the visual axes up to 60 degrees, or separated to suit a divergence of as much as 30 degrees.
Page 88 - ... steam and water, immediately upon issuing, expanded to a much greater size. The orifice was lined with an incrustation of carbonate of lime, and around it, and particularly on the southeast side, stood a miniature grove of slender stalagmitic arborescent concretions of the same substance. They were from half an inch to one and a half inches in diameter, and from four to eight inches in height. Many of them were branched, and the tips colored red, contrasting beautifully with the marble-whiteness...
Page 67 - After six years of age amblyopia ex anopsia seldom takes place to any great extent.
Page 67 - A child with good vision in each eye, who develops a constant monolateral squint at the age of six or eight months, will, in the absence of proper treatment, become rapidly blind in the squinting eye. This loss of vision in the deviating eye is so rapid that the power of central fixation is often lost within eight or ten weeks.
Page 25 - ... brain centers; training the muscles of the eyes when defects exist, and operating when the above fails. Two essential conditions are present in every case of concomitant squint.* First: Abnormal convergence of the visual axis. Second: Defective fusion faculty. Other conditions may also be found. The vision of the eye which is not being used for fixation is almost invariably suppressed. Third: There is in rather rare instances, more or less congenital amblyopia. Fourth: There is very often acquired...
Page 129 - ... 2. \\ 77 \ Slides for second grade fusion. of two tubes joined with a hinge with means for both lateral and vertical adjustment. CONVERGENT SQUINT of this class are a clown and a hoop, a mouse and a trap, a clock-face and hands, etc. "(2) Devices of the second class, of which Fig. 2 is an example, require true fusion of images in order that the full picture may be seen. " The pictures on each pair of slides are exactly similar, except Fio. 3.
