PURPOSE To assess outcomes of levator resection for the surgical correction of congenital and acquired upper lid ptosis in patients with fair to good levator function and evaluation of the relationship between demographic data and success of this operation. METHODS In a retrospective study, medical records of patients with blepharoptosis who had undergone levator resection over a 10-year peri...

purpose: to compare mersilene mesh and autogenous fascia lata in the management of low-function ptosis. methods: a randomized clinical trial was performed on 31 eyelids with poor levator function. patients were randomly assigned to two groups: 16 eyelids in the mersilene mesh group and 15 eyelids in the autogenous fascia lata group. results: nine patients with congenital unilateral and 11 patie...

OBJECTIVES To evaluate the use of botulinum toxin (BTX) induced ptosis in the treatment of corneal pathology. METHODS We employed two BTX injections into the superior lid of 10 eyes (9 patients). We evaluated the degree of ptosis, its duration and the effect on the corneal lesion. RESULTS Complete ptosis resulted in seven eyes and the corneal pathology resolved in all of them. There were no...

In skeletal myogenic differentiation, myoblasts fuse with myogenic cells spontaneously, but do not fuse with non-myogenic cells either in vivo or in vitro, suggesting that the fusion of myoblasts with non-myogenic cells is unsuitable for differentiation. To understand the inevitability of the fusion among myoblasts, we prepared heterokaryons in crosses between quail myoblasts transformed with a...

-To assess cellular mechanisms mediating myogenic responses of interlobular artery (ILA), experiments were performed with the use of isolated perfused hydronephrotic kidneys. ILAs were divided into 3 groups according to their basal diameters: proximal (>60 microm), intermediate (40 to 60 microm), and distal (<40 microm) ILAs. Myogenic responses were obtained by stepwise increase in perfusion pr...

Duchenne muscular dystrophy (DMD) is a severe X-linked recessive muscle disorder caused by mutations in the dystrophin gene. Nonetheless, secondary processes involving perturbation of muscle regeneration probably exacerbate disease progression, resulting in the fatal loss of muscle in DMD patients. A dysfunction of undifferentiated myogenic cells is the most likely cause for the reduction of re...

Objective: To compare the frequency of good functional outcome frontalis suspension surgery using silicone rod versus prolene 4/0 suture in simple congenital ptosis. Study Design: Hospital Based Comparative Study. Setting: Department Ophthalmology, Khyber Teaching Hospital, Peshawar. Period: June to August 2018. Material &amp; Methods: This study was performed on 70 randomly selected patients d...

PURPOSE This was a retrospective study to compare the efficacy and efficiency of a new small anterior incision, minimal dissection ptosis procedure with that of a traditional anterior aponeurotic approach for the correction of aponeurotic ptosis. METHODS The results of a chart and photograph review of 36 patients with 49 ptotic eyelids who had ptosis correction by a small-incision, minimal di...

To evaluate the basic technique of Ptosis probe R and the impact of ptosis repair by silicone rod frontalis sling on the Asian eyelid. A retrospective interventional study including 30 patients (49 eyelids) who underwent silicone rod frontalis suspension by the same surgeon between 2005 and 2008. Cosmetic outcomes , marginal reflex distance (MRD), chin-up head posture and recurrence rate were e...
