Periorbital necrotizing fasciitis: clinical perspectives on nine cases.

A multicenter review of Periorbital Necrotizing Fasciitis including nine cases, aged 41 to 82, mostly female, and mainly post-traumatic or idiopathic. Streptococcus pyogenes was the most frequent pathogen. Treatment involved debridement alongside antibiotic therapy in all cases. Two cases experienced toxic shock, with no fatalities. Visual outcomes varied from exenteration to preserved visual acuity with minimal aesthetic impact. Early detection and prompt intervention are paramount due to the significant risks associated with this condition, which may lead to severe complications ranging from vision loss to systemic decline or death.

Medial Canthal Tendon Reflecting in Lower Eyelid Reconstruction After Palpebral Cancer Surgery: Description of a New Technique.

PURPOSE: The aim of this article is to describe a new reconstructive technique of the lower eyelid in the surgery of tumors involving the medial canthal tendon. METHODS: Our new technique consists of detaching and reflecting the most medial portion of the anterior medial canthal tendon and reinserting it into the posterior lamella. We describe the cases in which our technique can be useful, as well as the results we have obtained. RESULTS: The result after a year of follow-up showed no disruption of the angulation of the lower eyelid line and no changes in eyelid position. CONCLUSIONS: The medial canthal tendon reflection could provide both aesthetic and functional results that may be superior to the usual techniques.

Eyelid atypical fibroxanthoma: a rare challenging entity.

Atypical fibroxanthoma (AFX) is a rare neoplasm, with a limited number of cases reported in the periocular region. In this case report, we detail a 63-year-old woman who presented with a polypoid, exophytic lesion on her right upper eyelid that had been progressing for a year. The lesion was meticulously excised with security margins and reconstructed using a glabellar flap. Following a thorough microscopic and immunohistochemical analysis, AFX was diagnosed. Despite its sometimes clinical and histological benign appearance, AFX is classified as a malignant neoplasm; however, it carries an excellent prognosis with low metastasis and recurrence rates. Complete excision with safety margins is essential and an adequate post-operative surveillance is recommended. Owing to its rarity, ophthalmologists should remain vigilant and include AFX in their differential diagnosis, as the tumor's benign appearance may lead to misdiagnosis of this malignant entity.

Periumbilical fat auto-graft associated to a porous orbital implant for socket reconstruction after enucleation.

Having to remove the sclera, fat and the optic nerve in patients undergoing an enucleation, translates in a larger volume that needs to be replaced to achieve good motility and aesthetic results. Using a 20 or 22 mm implant can only partially replace the removed volume. We report the results of our enucleation technique, which includes the use of a porous orbital implant combined with a primary fat graft to replace a higher percentage of the removed volume to achieve a better cosmetic outcome and to avoid implant related complications in high risk patients. Prospective, non-randomized study of enucleated patients for whom porous orbital implantation was performed with anterior placement of a fat auto-graft. The development of implant extrusion or exposure was recorded as well as the presence of conjunctival wound dehiscence and infection. Orbital volume was clinically and radiologically evaluated as well. Twenty-eight patients were included, with a postop follow-up of at least 6 months (6-79 months). No cases of migration or extrusion were found. One case of a large exposure resolved completely. All MRI demonstrated proper implant-graft integration and vascularisation. The aesthetic result and the symmetry were very adequate, with Hertel differences of less than 2 mm in all cases and good motility range. The fat graft is well tolerated, showing low incidence of implant-related complications whilst maintaining good volume and motility.

Direct frontalis flap with and without levator pulley for correction of severe ptosis with poor levator function in the same patient.

PURPOSE: To compare two techniques of frontalis muscle flap suspension in different eyelids of the same patient for correction of severe ptosis with minimal levator function. MATERIAL AND METHODS: A prospective study of four patients with severe bilateral ptosis and poor levator function, who underwent direct frontalis muscle flap on the right eyelid and frontalis muscle flap with levator pulley on the left eyelid was conducted. Eyelid studies measurements were taken at baseline, 2 months, one year and 5 years after surgery. The presence of complications, flap function and palpebral contour were evaluated. RESULTS: Despite the surgical technique performed, good results in terms of functionality, contour and aesthetics were observed. In the eyes that underwent frontalis muscle flap (FMF)-direct, there were 2 cases with moderate anteriorization of eyelid margin in extreme upgaze and all patients showed eyelash ptosis that persisted one year after surgery, but improved after 5 years. In the eyes that underwent FMF-pulley, no upgaze anteriorization of eyelid margin was observed and three patients had eyelash ptosis of lesser extent than the fellow eye, improving after 1 year follow-up. FMF-pulley showed more long-term stability in eyelid height, compared with FMF-direct. CONCLUSIONS: Frontalis muscle flap with a pulley in the levator aponeurosis prevents some complications caused by the excessive vertical component of the direct frontalis muscle flap, especially in deep-set eye patients, with better stability of the eyelid height and contour over time.

Visian toric implantable collamer lens for correction of compound myopic astigmatism.

PURPOSE: To assess the safety, efficacy, predictability, and stability of a toric posterior chamber phakic intraocular lens for the correction of myopia with astigmatism. METHODS: A non-randomized, retrospective analysis of 63 eyes of 36 patients with a minimum follow-up of 6 months was performed. The STAAR Toric Implantable Collamer Lens (TICL) was implanted under topical anesthesia through a 3-mm temporal clear corneal incision. Mean preoperative spherical equivalent refraction was -10.71+/-3.55 diopters (D). Median preoperative best spectacle-corrected visual acuity (BSCVA) was 20/25, with a mean sphere of -8.78 D (range: -2.50 to -16.50 D) and mean cylinder of 3.60 D (range: 1.25 to 7.00 D). Postoperative parameters were analyzed at different time points, and vector analysis was performed to calculate surgically induced astigmatism. RESULTS: Fifty-nine (93.6%) eyes had a spherical equivalent refraction within +/-1.00 D and 52 (82.5%) eyes were within +/-0.50 D of emmetropia. Median postoperative uncorrected visual acuity was 20/25 and BSCVA was 20/20. Preoperative keratometric astigmatism was 1.99@178.2 vs 1.82@178.6 postoperative keratometric astigmatism, most likely due to the surgical incision. Preoperative refractive astigmatism was 2.17@93 whereas postoperatively it reduced to 0.38@99.6. No eye lost 2 or more lines of Snellen BSCVA. Twenty-two (34.9%) eyes gained 2 or more Snellen lines of vision. Preoperatively, 45 (71.4%) eyes had a BSCVA of 20/30 or better, whereas 60 (95.2%) eyes were within this range of BSCVA after surgery. The TICL demonstrated good rotational stability in this study. CONCLUSIONS: Implantation of the STAAR TICL was an effective, predictable, and safe method for correction of high myopia and myopic astigmatism as shown in this retrospective observational series.

Thyroid orbitopathy obscuring the diagnosis of a rare neuromuscular hamartoma of the superior rectus muscle in an adult.

A neuromuscular hamartoma is a rare benign tumour that is most frequently associated with peripheral nerves. The authors present a case of a 61 year-old man with bilateral exophthalmos and lid retraction who developed further proptosis and chemosis in the left eye over a five month period. An initial diagnosis of thyroid orbitopathy was made and he had a limited response to two courses of oral steroid administered in another centre. He was subsequently referred to our institution for further management when his condition worsened following withdrawal of treatment. Orbital CT scan showed a thickening of the recti muscles and particularly the left superior rectus and overlying soft tissue. Given this unusual pattern of muscle involvement in thyroid orbitopathy, a muscle biopsy was performed. This showed the presence of a neuromuscular hamartoma without malignant features. The orbital fat biopsy showed no pathological findings. A neuromuscular hamartoma not associated with a peripheral nerve is a rare entity, especially when coupled with an extraocular muscle. We wish to highlight the importance of a muscle biopsy when faced with a clinical picture and radiological pattern of extraocular muscle enlargement not typical of what we know to occur traditionally in thyroid eye disease.

Autologous serum eye drops used to treat an ulcerated dermis-fat graft.

A 49-year-old woman with a contracted and keratinized anophthalmic socket underwent a dermis-fat graft for orbital augmentation. She presented with an early ulcer on the surface of the dermis, with inhibited conjunctival growth. There was no improvement after 1 month of conservative treatment. The authors applied autologous serum eye drops to accelerate epithelial repair, with resolution of the ulcer and reduction of surface keratin within 3 weeks. This is the first report of dermis-fat graft ulcer treated with autologous serum.

Orbital metastases from male breast cancer in two cases.

We present 2 cases of orbital metastases of male breast cancer, a very rare association in the context of a rare disease. We also provide a review of the literature on this topic including the 4 previously reported cases. Our cases presented with diplopia and proptosis. Orbital biopsies were performed that revealed metastases of infiltrative ductal carcinoma (ICD).

Frontalis muscle flap advancement with a pulley in the levator aponeurosis in patients with complete ptosis and deep-set eyes.

PURPOSE: To offer an alternative to frontalis sling techniques to achieve a more horizontal traction vector force with the frontalis muscle flap. The proposed technique avoids malpositions such as pulling the upper eyelid in an anterior plane during maximum opening and ptosis of the eyelashes. METHODS: The technique, performed in 5 patients with complete unilateral ptosis and an absence of levator function, consisted of advancing a flap of frontalis muscle and creating a pulley with the aponeurosis of the levator muscle. Mean follow-up was 12 months. RESULTS: Ptosis was corrected in all 5 patients, with good aesthetic outcome. There were no cases of anterior eyelid advancement, entropion, or eyelash ptosis. The only complication was 1 case of lagophthalmos with corneal erosion. CONCLUSIONS: In this preliminary series, the technique was safe and effective for correcting severe blepharoptosis, with good aesthetic and functional results even in patients with deep-set eyes and without the eyelid malpositions that commonly occur in frontalis sling techniques.
