Our previous work demonstrated that the 12-lipoxygenase metabolite of arachidonic acid, 12(S)-hydroxyeicosatetraenoic acid [12(S)-HETE] induced a nondestructive and reversible retraction of cultured endothelial cells. In the current study we tested the hypothesis that tumor cells produce 12(S)-HETE during their interactions with endothelial cells which in turn induces endothelial cell retractio...

DUANE'S retraction syndrome (Duane, 1905) is frequently but not invariably associated with convergent strabismus when the eyes are in the primary position (Duke-Elder, 1964); if a head-turn is present, it will be in the direction of action of the paretic lateral rectus muscle. In the atypical retraction syndrome, the medial rectus is more paretic than the lateral rectus muscle; there is exophor...

Duane (I905) emphasized six features of a characteristic congenital ocular motility syndrome: (i) Complete, or less often partial, loss of abduction of the affected eye; (2) Partial, or rarely complete, restriction of adduction of the aHected eye; (3) Retraction of the affected eye into the orbit on adduction; (4) Oblique overshoot of the affected eye either up and in or down and in on adductio...

INTRODUCTION The surgical correction of anomalous movement such as upshoot in Duane syndrome is challenging. Lateral rectus muscle disinsertion and reattachment to the lateral orbital wall is a new approach used to minimize or eliminate the effects of co-contraction including globe retraction, palpebral fissure narrowing and anomalous vertical movement. CASE PRESENTATION We report a case of a...

The purpose of this comparative study was to evaluate a long-term efficacy of lateral rectus muscle resection in the affected eye of patients with Duane retraction syndrome (DRS) with esotropia and limited abduction and to compare it with bilateral medial rectus recessions. We reviewed and compared the data of the group A with 23 patients who underwent a recession-resection procedure and the gr...

Purpose: Capsular related complications may occur during and/or following cataract s”rPew. Methods: We used endocapsular PUMA rings (EPR) to prevent such complications in eyes with pre or peroperative zonular c’ehiscence, high myopic eyes and eyes witl: exfoliation syndrome which have weak zonoles. EPR can be implanted easily through the phaco-incision before aspiration of the cortex or just be...
