MICROPHTHALMUS, MIOSIS AND CALCIFIED LENS.

J. J. HORTON, M.D.

EAGLE PASS, TEXAS.

Augustina Luna, Mexican girl, age 9 years, blind in both eyes since birth. The eyes are small and sunken, and the orbital regions of both sides have not kept pace with the other parts of the face in growth.

Right: The lids are small, in keep-

round, except for this little tear. I t does not react to the usual stimuli or to atropin or cocain. A chalky white object occupies the pupil.

Left: Lids and conjunctiva as in R., cornea round and 7.5 mm. in diam­eter. Anterior chamber very shallow. Iris appears normal. Pupil 1 mm. in diameter. It does not react to light, accommodation, atropin or cocain. It is also occupied by a chalky white ob­ject.

The movements of the eyes are full

Figures 1 and 2. Microphthalmus, miosis and calcified lens. to right and left.

Congenital defects. Free turning of eyes

ing with the size of the eye. Conjunc­tiva normal. The globe'is much smaller than normal. The cornea is oval, measuring 8 mm. in the horizontal and 5 mm. in the vertical diameter. It is clear. The temporal third of the iris is muddy in color, and is in contact with the cornea. The remainder is of normal dark brown color and is healthy in appearance. The nasal part of the anterior chamber is very shallow. The pupil is 1 mm. in diameter and is torn slightly at 8 o'clock, where the iris is in contact with the cornea. It is

and conjugate to right or left, but the patient has practically no control of them in the up or down movement, not being able to hold them in position long enough to be photographed well.

Both eyes: Corneal incision with keratome, enlarged with pince-cis-seaux; optical iridectomy; removal of calcified lens with hook and forceps. No results so far as vision is concerned. The parents would not permit the enucleation of either eye "for the ad­vancement of science."
