Horizontal squint surgery. The mathematical approach.

Horizontal squint surgery. The mathematical approach.

STANDARDIZATION of the surgical treatment of strabismus has long been the ambition of surgeons. Even for the most experienced the number of millimetres of recession or resection to perform is always a difficult decision. Because of individual variation in response to similar surgical procedures, Cooper (1961) believed it difficult to predict the result. Knapp (1958) considered accurate estimati...

Simplified limbal approach in squint surgery.

The limbal approach is not new to squint surgery* but, despite its considerable advantages in exposure and subsequent healing, the methods described so far are not easy to perform to obtain the best final results. In particular, the incision commonly described needs very accurate suturing of the conjunctival flap with its two radially placed incisions to achieve a good cosmetic result. The meth...

Adjustable sutures in squint surgery.

New suture material for squint surgery.

All operations were performed under general anaesthesia using a limbal approach to the insertions of the muscles, similar to that recently described by Fells (I97 i). The 6/o Ethiflex suture was then used in the standard manner employing a "whip" stitch on the edge of each muscle. At the moment the suture is presented with a io-mm. taper-point needle. This is not ideal, but no problems, apart f...

Use of miotics in squint surgery.

AFIER operations for convergent squint, a comparatively frequent result is that the eyes are straight for distance, but on attempting near vision, the squint reappears. It happens even after a full recession of both medial recti and after the fullest possible spectacle correction. This residual acconmmodational squint proves a great handicap to the full restoration of binocular single vision an...
