purpose: to evaluate the outcomes of ptosis surgery in patients with weak levator function using orbicularis oculi and frontalis muscles. methods: this prospective interventional case series study was conducted over 3 years on patients with ptosis and weak levator function (less than 4mm). in all cases, orbicularis oculi and frontalis muscles were used directly to correct the ptosis. success wa...

IMPORTANCE Understanding the prevalence and clinical features of eyelid malpositions in facial nerve palsy (FNP) may inform proper management of patients with FNP and supplement our knowledge of eyelid physiology. OBJECTIVE To describe eyelid malposition in FNP. DESIGN, SETTING, AND PARTICIPANTS In this retrospective cohort study, patients with FNP seen at the Center for Advanced Facial Pla...

AIMS To explore the relationship between the amount of resected Müller's muscle-conjunctiva (MMCR) and clinical outcome in patients undergoing upper eyelid ptosis surgery. METHODS 49 patients underwent 87 MMCR surgeries. The total areas of the specimen and of MM were measured in pixels. RESULTS The average percentage of muscle tissue in relation to total excised tissue was 21%. Intraoperati...

BACKGROUND Treatments for severe blepharoptosis are well documented and include the most common operations for restoring upper eyelid ptosis, which are levator surgery and frontal muscle transfers; however, the choice of treatment is still controversial. There are different approaches to the restoration of upper eyelid ptosis, and the choice will be based on ptosis severity and the surgeon's sk...

From January 2020 July 2020, we conducted a hospital-based, descriptive, observational study. Material methods: Three hundred eighty individuals age15 years above were included in Exophthalmometric value (EV) outer inter-canthal distance ...

800x600 to analyse the effect of congenital unilateral ptosis on the ocular higher order aberrations (hoa) and to compare these eyes with normal fellow eyes this study has been performed. in this observational comparative case series, 16 eyes of 16 patients less than 15 years old with congenital unilateral upper eyelid ptosis were included. corrected distance visual acuity (cdva), corneal topog...

PURPOSE To quantify the palpebral alterations occurring in subjects after the age of 50 years. METHODS An observational study was done with 325 subjects older than 50 years. The data comprised measurements of intercantal distance, palpebral fissure length and height, external and internal eyelid angles, margin reflex distance (MRD) and total palpebral fissure area. Digital images were obtaine...

PURPOSE To compare external levator advancement and Müller's muscle-conjunctival resection (conjunctivomullerectomy, or CJM) for correction of upper eyelid involutional ptosis. DESIGN Retrospective, nonrandomized, comparative interventional case series. METHODS Review of medical records of 159 patients (272 surgical procedures) who underwent external levator advancement or CJM was performed...

PURPOSE To evaluate the efficacy of transconjunctival Müller muscle recession and graded levator disinsertion for eyelid retraction in patients with thyroid-related orbitopathy (TRO). DESIGN Retrospective consecutive case series. METHODS Medical record review of 78 TRO patients (107 eyelids) who underwent surgery for upper eyelid retraction in a 5-year period was performed. Main outcome mea...

BACKGROUND Markus-Gunn Jaw-winking Phenomenon (MGJW) is a congenital ptosis associated with synkinetic movement of upper lid on masticating movements of jaw. It results from aberrant connection between motor division of trigeminal nerve and oculomotor nerve. OBJECTIVE To investigate the clinical characteristics of MGJW phenomenon and evaluate its surgical outcomes of unilateral levator excisi...
