Congenital ptosis

Causes

• Congenital blepharoptosis presents within the first year of life, alone or as part of ocular or systemic syndromes; surgical repair is technically challenging and more than one operation is not uncommon (PMID 24657037).
• Marcus Gunn jaw-winking syndrome is a congenital synkinetic ptosis in which the eyelid rises involuntarily with jaw movement, from aberrant wiring between the trigeminal and levator nerves (PMID 40248446).
• Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is an autosomal dominant malformation combining ptosis with a shortened eyelid opening and reversed epicanthal folds; in 8 molecularly confirmed patients, MRI and histopathology showed a thin, disorganized anterior levator aponeurosis but a well-formed posterior muscle belly, unlike the fatty degeneration seen in simple congenital ptosis (PMID 22159675).
• Anderson's landmark series, 123 consecutive surgical ptosis patients: amblyopia in 20% overall, with 3.2% (4 cases) attributed to the ptosis itself (PMID 7387510).
• 55 children with unilateral congenital ptosis: amblyopia in 15 (27%), from anisometropia in 10 and strabismus in 2; amblyopia developed after ptosis surgery in 3 cases (PMID 6871790).
• 36 patients: amblyopia in 19%; severe nonocclusive ptosis (4mm or more) correlated significantly with amblyopia, and no new amblyopia cases developed after surgical repair (PMID 8532286).
• 83 eyes: amblyopia present in 48% of eyes with measurable acuity; 26% of amblyopic eyes had no cause other than the ptosis (stimulus-deprivation amblyopia), all in eyes with severe ptosis (PMID 20349903).
• Meta-analysis of 24 studies: amblyopia prevalence 22.7% (95% CI 18.5-27.8%), myopia 30.2%, astigmatism 22.2%, strabismus 19.6%, anisometropia 17.3% (PMID 29844360).
• 265 patients (346 eyes): strabismus rate 12.45% and amblyopia rate 36.98%, both higher than the general population (P<0.01), more pronounced in unilateral cases (PMID 33538502).
• 48 eyelids after frontalis sling surgery: amblyopia at final follow-up in 35.4%; risk factors were blepharophimosis (P=0.017), preoperative MRD1 of -1.0mm or less (P=0.038), preoperative lid fissure 4.5mm or less (P=0.035), preoperative anisometropia (P=0.011) and postoperative astigmatism (P=0.026) (PMID 30463547).
• National cross-sectional study, 866 children with congenital ptosis: ADHD diagnosed in 18.01% against 5.6%-7.6% in the general pediatric population; associated factors included male sex, diagnosis after age 1, eyelid patching for amblyopia, residual ptosis, ptosis surgery and levator resection specifically (PMID 42744595).

How it is done

• Fascia lata slung from the tarsus to the frontalis muscle, so brow movement lifts the lid, was described as a ptosis operation by Jay in 1976 (PMID 1070858).
• A Cochrane review found 3 randomized trials (160 participants total) comparing 4 sling materials: polytetrafluoroethylene (Gore-Tex), Ethibond suture, Mersilene mesh and autogenous fascia lata; each trial compared a different pair, so no material could be identified as optimal (PMID 31013353).
• 123 patients: silicone rod slings showed better cosmetic results than preserved fascia lata slings from 1 year onward (P<0.05 at each interval); 3-year recurrence was 29.2%/11.1% (bilateral/unilateral) with silicone against 63.2%/41.4% with preserved fascia lata (PMID 19019443).
• Maximal levator resection, dividing the medial and lateral horns of the levator aponeurosis while preserving Whitnall's ligament, was proposed in 1994-1999 as an alternative to frontalis suspension for congenital ptosis with levator function under 2mm; satisfactory eyelid elevation was achieved in 36 of 44 children (81.8%) (PMID 12045925).
• A small-incision levator resection technique in 50 eyes raised MRD1 from 1.78mm to 3.95mm (P<0.001), with excellent or good results in 74.5% of cases (PMID 29744575); levator plication produced a smaller MRD1 gain than resection in a 20-eye comparison (1.12mm against 2.8mm, P=0.001) and more postoperative drooping from the fourth week (PMID 20302407).
• Müller's muscle resection raised MRD1 a mean 2.54mm in 11 patients, with better correction when levator or Müller function was good beforehand (4.28mm) than when both were poor (1mm) (PMID 21574798); combined with tarsectomy in 36 congenital ptosis patients with fair-to-good levator function, it raised MRD1 a mean 2.79mm (P<0.0001) (PMID 31162300). A 2026 modification adding levator plication to an extended Müller's muscle resection in 34 eyes with poor levator function (5mm or less) reached a 76.5% success rate at 6 months (PMID 41588142).
• Timing: 82 infants under 2 years old with vision-obscuring ptosis underwent fascia lata slings at a mean age of 15.3 months, with good or fair results in 78.0% (PMID 24582995); a 44-patient series found levator resection outcomes and recurrence rates were better when surgery was done at ages 2-4 than later (PMID 28812934); a 56-patient study found postoperative refractive error did not move toward normal and astigmatism significantly worsened (P=0.0255), concluding anisometropia alone should not drive early surgery (PMID 30789542). A 2023 review notes current techniques can over- or under-correct, in part from patient age, cooperation during preoperative measurement, and intraoperative swelling or bleeding (PMID 36114384).

Results and evidence

• 103 eyelids: frontalis muscle suspension had a higher success rate than levator muscle surgery (87.3% against 60.4%, P=0.002) despite the suspension group being younger and having worse preoperative findings; both groups had a 25% reoperation rate (PMID 37195337).
• Meta-analysis of 16 studies comparing levator-based and frontalis-based surgery for poor-function congenital ptosis: no significant difference in postoperative MRD1; levator-based surgery had a lower risk of recurrence and of implant- or suture-related complications, with comparable postoperative lagophthalmos (PMID 41179375).
• 50 patients with severe unilateral poor-function ptosis: complete success was higher with frontalis sling at 1 month (50% against 20.8%, P=0.02) but higher with tarsoconjunctival Müller's-muscle resection plus levator resection at 6 months (50% against 38.4%, P=0.03) (PMID 36017040).
• Randomized trial, 44 patients with poor levator function: tarsofrontalis silicon-rod sling and supramaximal levator resection produced good outcomes in 73-77% of both groups, with MRD1 and fissure height improving significantly in each (P<0.001) (PMID 36070117).
• 152 eyelids with poor levator function: postoperative MRD1 was comparable between maximal levator resection (2.8mm) and frontalis sling with autogenous fascia (3.0mm), lowest with preserved fascia (2.2mm); lagophthalmos was least with preserved fascia (0.6mm) against autogenous fascia (1.9mm) and levator resection (1.9mm) (PMID 32651544).
• 243 eyelids, maximal levator resection for poor levator function: excellent or good results in 93.0%, unrelated to preoperative levator function, MRD1 or levator dehiscence (PMID 27601423).
• 154 patients, levator resection for simple congenital ptosis: levator function rose from a mean 8.81mm to 11.29mm; overall success rate 81.8%, with older age, local anesthesia and milder ptosis predicting success (PMID 35120910).

Risks and complications

• 243 eyelids after maximal levator resection: exposure keratopathy in 11.1%, lid crease asymmetry and entropion each in 8.2%, overcorrection in 3.3%, eyelash ptosis in 3.7%, temporal eyelid droop in 3.3%, suture abscess and conjunctival prolapse each in 0.8% (PMID 27601423).
• 3 children developed pre-aponeurotic fat prolapse (overhanging upper lid tissue) after unilateral levator resection; a second procedure at a mean 4.3 months later improved the sulcus and crease symmetry (PMID 30747974).
• A 5-year-old with BPES developed bilateral Candida and atypical mycobacterial infection 4 weeks after silicone-rod frontalis sling placement, cured with intravenous antibiotics, antifungals and sling removal (PMID 23381566).
• 22 pediatric patients with recurred ptosis after silicone-rod frontalis suspension: the breaking strength of explanted rods had fallen roughly 50% over 3 years, with cracking and disintegration on microscopy; pretarsal fixation points migrated upward and suprabrow points migrated downward as recurrence developed (PMID 28207846).
• Refractive change after surgery is not always favorable: a 56-patient series found astigmatism significantly worsened after ptosis repair (P=0.0255) rather than normalizing (PMID 30789542).

Recovery

• The pediatric congenital-ptosis literature reviewed here reports follow-up and recurrence-surveillance intervals, not day-by-day recovery detail; a fascia-lata sling series followed patients a mean 54.8 months (PMID 24582995) and a Marcus Gunn series a mean 36.9 months (PMID 10366092). No source in this review reported bruising, swelling or activity-restriction data specific to congenital ptosis surgery in children.

Combined procedures

• Moderate-to-severe Marcus Gunn jaw-winking ptosis: levator excision (unilateral or bilateral) followed by bilateral frontalis suspension resolved jaw-winking completely in 37.0% of 27 treated eyelids and left only mild winking (1mm or less) in 48.2%; results were good in 68.4% of the 19 patients who had bilateral levator excision (PMID 10366092). A 2025 systematic review found surgery effective overall but says long-term follow-up and more comparative data are needed to establish an optimal technique (PMID 40248446).
• BPES surgery combines ptosis repair (frontalis suspension with a polytetrafluoroethylene sling) with medial canthoplasty for the epicanthal folds; in 24 children under 3, one-stage and two-stage correction produced comparable improvement in eyelid and canthal measurements, with the two-stage approach showing a nonsignificantly higher rate of good blepharophimosis correction (46% against 27%) and the one-stage approach a nonsignificantly higher rate of good ptosis correction (64% against 46%) (PMID 41265558).
• Congenital ptosis surgery differs from the acquired (involutional) ptosis repair covered in blepharoptosis-repair.md: congenital cases involve a dystrophic levator muscle rather than aponeurotic dehiscence, which is why frontalis suspension and maximal levator resection feature more heavily here than in adult aponeurotic repair.

Current questions

• Levator-based against frontalis-based surgery for poor levator function remains unsettled: a 16-study meta-analysis favors levator-based techniques for fewer recurrences and complications (PMID 41179375), while a 50-patient trial found frontalis sling better in the short term and combined Müller's-muscle/levator resection better by 6 months (PMID 36017040).
• The optimal frontalis sling material is still unresolved; the only Cochrane review on the question found just 3 small trials, each comparing a different pair of materials, insufficient to name a preferred one (PMID 31013353).
• Surgical timing guidance conflicts on how much weight to give refractive error: some series support surgery at 2-4 years or before age 5 for better outcomes and amblyopia prevention (PMID 28812934), (PMID 33538502), while a 56-patient study argues anisometropia alone should not be the deciding factor since astigmatism did not improve after surgery (PMID 30789542).
• Extending Müller's-muscle-conjunctival resection, normally used for good levator function, to poor-function congenital ptosis is new and reported in only a 34-eye series so far (PMID 41588142).
• The association between congenital ptosis and ADHD was reported for the first time in a 2026 national study and has not yet been replicated (PMID 42744595).

Terms

• Levator function (excursion): how far the upper lid travels from down-gaze to up-gaze; poor function usually favors frontalis suspension over levator surgery (PMID 12045925).
• MRD1: distance from the corneal light reflex to the upper eyelid margin, the main measure of ptosis severity and surgical result (PMID 19019443).
• Frontalis sling (suspension): a strip of material connecting the tarsus to the frontalis muscle so brow elevation lifts the eyelid, used for poor levator function (PMID 1070858).
• Autogenous versus preserved fascia lata: sling material harvested from the patient's own thigh versus donor fascia processed for banking; the two differ in recurrence rate (PMID 19019443).
• Silicone rod / PTFE (Gore-Tex) sling: synthetic frontalis sling materials, alternatives to fascia lata (PMID 31013353).
• Maximal levator resection: near-complete mobilization and shortening of the levator muscle for congenital ptosis with poor levator function (PMID 12045925).
• Müller's muscle-conjunctival resection (MMCR): shortening Müller's muscle and conjunctiva from the inside of the lid, generally reserved for good levator function (PMID 21574798).
• Marcus Gunn jaw-winking syndrome: congenital ptosis with synkinetic eyelid elevation on jaw movement (PMID 40248446).
• Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES): an inherited syndrome combining ptosis, a shortened eyelid opening and reversed epicanthal folds (PMID 22159675).
• Deprivation (stimulus-deprivation) amblyopia: reduced vision from a pupil physically blocked by the ptotic lid during infancy, distinct from anisometropic or strabismic amblyopia (PMID 20349903).
