Adjustable versus non-adjustable sutures for strabismus.
BACKGROUND Strabismus, or squint, can be defined as a deviation from perfect ocular alignment and can be classified in many ways according to its aetiology and presentation. Treatment can be broadly divided into medical and surgical options, with a variety of surgical techniques being available, including the use of adjustable or non-adjustable sutures for the extraocular muscles. There exists ...
متن کاملADJUSTABLE SUTURE IN STRABISMUS SURGERY
Adjustable suture in strabismus surgery is a way to get accurate alignment of the eyes after operation. This technique is used in cooperative patients, being either adults or children. We report the result of this technique in 120 patients, 70 with esotropia and 50 exotropia. The amount of deviation was between 20 and 60 prismdiopters. The patients were mostly adults and teenagers. and the...
متن کاملResolution Acuity is better than Vernier Acuity
Our impressive sensitivity to vernier offsets as compared to resolution acuity has long inspired vision researchers to study the phenomena in great detail. In this study we use the test-pedestal framework to compare resolution and vernier acuity. In these experiments the test stimulus is the same for both tasks, only the pedestals differ. When thresholds are expressed in common units of test st...
متن کاملAdjustable References
Even when programming purely mathematical functions, mutable state is often necessary to achieve good performance, as it underlies important optimisations such as path compression in union-find algorithms and memoization. Nevertheless, verified programs rarely use mutable state because of its substantial verification cost: one must either commit to a deep embedding or follow a monadic style of ...
