The European Neuromuscular Centre (ENMC) derived the term Congenital Cranial Dysinnervation Disorders in 2002 at an international workshop for a group of congenital neuromuscular diseases. CCDDs are congenital, non-progressive ophthalmoplegia with restriction of globe movement in one or more fields of gaze. This group of sporadic and familial strabismus syndromes was initially referred to as the 'congenital fibrosis syndromes' because it was assumed that the primary pathologic process starts in the muscles of eye motility...

The measurement of the amount and nature of deviation is the essence of diagnostic workup of a patient with strabismus and also has important therapeutic implications while planning the amount of surgery or prescribing therapeutic prisms. Although Krimsky test is a useful method, it cannot be used to measure deviation in patients with scarred and irregular cornea with an anechoic posterior segment making it difficult to see the corneal reflex. We hereby take the opportunity to present a modification of the original Krimsky test which is extremely helpful in determining the deviation in patients with irregular opaque corneas...

Sri Ganesh, Sheetal Brar, Kritika Chopra
Posterior lenticonus is a rare progressive disease characterized by protrusion of posterior lens capsule along with lens cortex into the vitreous cavity. It may be associated with local thinning or absence of posterior lens capsule. It generally occurs sporadically, but familial cases have also been reported. If visually significant or if amblyopia is present, lens removal is indicated. Treatment consists of clear or cataractous lens extraction, optical correction along with prompt amblyopia therapy. In this case, we propose a "jellyfish sign" seen intraoperatively, which is referred to the characteristic movement of the posterior capsular cataractous material on injection of balanced salt solution in the capsular bag...
