RESUMO

Adenoid cystic carcinoma (ACC) is the most common malignant neoplasm involving the lacrimal glands, with high rates of recurrence and metastasis. During the pregnancy, reports of recurrence of ACC of the salivary glands and trachea have previously been published, but no lacrimal gland ACC recurrence has been reported. We present a 35-year-old woman with lacrimal gland ACC who was initially treated by surgical resection and adjunctive radiotherapy, but her cancer recurred during pregnancy, with rapid progression to cavernous sinuses and brain. Estrogen and progesterone receptors have been detected on lacrimal glands and ACCs of salivary glands. Thus, hormonal changes during pregnancy might contribute to the recurrence of ACC. However, the inherent invasive and recurrent nature of ACC could also account for the regrowth in this patient and further molecular studies can provide more accurate explanations.

RESUMO

Purpose: To report a 12-year-old patient with a rapid growing orbital mass and imaging findings suggestive of rhabdomyosarcoma that was found to be dirofilariasis after mass resection. Case Report: We describe a 12-year-old patient with a rapid growing orbital mass involving medial part of orbit and medial rectus muscle and imaging findings suggestive of rhabdomyosarcoma. Histopathologic examination showed the mass to be composed of granulomatous inflammation and the thread-like object to be Dirofilaria repens. The patient was well post-operation without morbidity. In this paper, we describe distinct clinical features and imaging findings of this interesting case. Conclusion: Deep orbital lesions due to dirofilariasis, as in our case, is extremely rare. It is important to add dirofilariasis to the differential diagnosis of orbital mass lesions. Attention to the imaging clues, as provided in this report, can be helpful.

RESUMO

BACKGROUND: The purpose of this study was to describe the radiologic and histopathologic features of lacrimal gland in patients presenting with lacrimal gland enlargement. METHODS: We retrospectively retrieved the data of patients with lacrimal gland enlargement in Farabi Eye Hospital between 2012 and 2017. These data included demographics, the patients' facial photographs, orbital CT-scans, and histopathological findings of lacrimal gland biopsies. RESULTS: Forty-seven patients (15 men and 32 women) were enrolled in this study with a median age of 37.9 years (range, 15-79 years). Histopathologic diagnoses were chronic dacryoadenitis in 26 cases (55.32%), IgG4-related disease in 6 patients (12.77%), two cases of acute dacryoadenitis, two cases of non-necrotizing granulomatous inflammation, two cases of Non-Hodgkin's B-cell lymphoma, two cases of adenoid cystic carcinoma and two cases of mixed tumor (4.26% each), as well as one case of conjunctival epithelial cyst, and one case of benign lymphoid tissue and fibrofatty tissue (2.13%). In two samples (4.26%), biopsy revealed normal lacrimal glands. Interestingly, in two cases with relapsing lacrimal gland enlargement, different histopathologic diagnoses were found in biopsies taken from each lacrimal gland at different times. The average size of enlarged lacrimal glands was 19.67 mm × 7.06 mm on axial CT scan and 19.44 mm × 6.20 mm on coronal CT scan. CONCLUSION: Tissue biopsy is needed for diagnosis of lacrimal gland enlargement because it is difficult to distinguish the type of the lacrimal gland pathology based solely on clinical or radiological presentation.

RESUMO

PURPOSE: Recession of levator muscle can potentially decrease the severity of corneal exposure by reducing margin-reflex distance 1. The purpose of this study is evaluation of effects of levator recession on lagophthalmos in facial palsy. MATERIALS AND METHODS: In a non-comparative case series of consecutive patients with exposure keratopathy due to facial paralysis between 2012 and 2017, levator recession was performed through lid crease incision. Small-size (⩽3 mm) lateral tarsorrhaphy was performed on a case-by-case basis for those with moderate-to-severe keratopathy. Preoperative and postoperative measurements of margin-reflex distance 1 and lagophthalmos were compared using paired t-test. RESULTS: Thirty-four patients (14 men and 20 women) were enrolled with an average age of 52.3 years. Mean follow-up was 13.3 months (range, 6-36 months). The most common etiology of facial paralysis was Bell's palsy (22 cases), followed by motor vehicle accident (8), parotid surgery (3), and brain tumor surgery (1). No additional procedure was performed for eight patients, while lateral tarsorrhaphy was performed in 26 cases. Mean margin-reflex distance 1 decreased from 5.0 ± 0.4 mm to 4.0 ± 0.5 mm (p < 0.001) and mean lagophthalmos decreased from 3.3 ± 0.9 mm to 1.8 ± 0.9 mm (p < 0.001). Subgroups of patients with additional lateral tarsorrhaphy and without tarsorrhaphy experienced the same amount of reduction in margin-reflex distance 1 and lagophthalmos. CONCLUSION: Recession of levator muscle was effective in reduction of margin-reflex distance 1 and lagophthalmos in facial palsy patients. This procedure can be added to the surgical armamentarium for management of patients with facial palsy and lagophthalmos.

RESUMO

PURPOSE: The purpose of this study is to introduce the results of a new surgical technique in patients with complete facial nerve palsy using the dynamic muscle transfer of orbicularis oculi muscle (OOM) flap from the contralateral side. METHODS: This case series presents a new surgical technique in three patients with complete facial palsy and lagophthalmos who were unresponsive to other modalities. In this technique, a rectangular flap of OOM was dissected from the upper lid of fellow eye and transferred to the affected eye through a subcutaneous tunnel over the nasal bridge. The flap was divided into two halves for upper and lower lids. Each half was incised longitudinally to increase the length of the flap and cover the lateral part of the affected eyelids. RESULTS: Improvement in exposure keratitis, lagophthalmos, and other related symptoms was observed as soon as the 1st week after the surgery. Partial blinking recovered and the operation was uneventful. CONCLUSION: Muscle flap transfer technique using contralateral OOM for complete facial palsy can be considered as a helpful alternative in patients who are still symptomatic despite conventional treatment modalities.

RESUMO

Purpose: To report the characteristics of lacrimal gland prolapse among the patients who underwent upper blepharoplasty.Materials and Methods: In a retrospective study, consecutive upper blepharoplasty patients with significant lacrimal gland prolapse were included. The degree of prolapse was measured as anterior protrusion of lacrimal gland from the orbital rim. Reposition of the lacrimal gland was performed by using non-absorbable sutures to fixate the gland to the periosteum of lacrimal fossa. In cases with unusually large lacrimal glands, an incisional biopsy of the gland was obtained. The orbital septum was left unsutured.Results: Twenty patients (19 females and one male) out of a total of 198 patients who underwent upper blepharoplasty (10.1%) had clinically significant lacrimal gland prolapse. Mean age was 54.8 ± 9.4 years (range, 31-69). Fourteen patients (70%) were asymptomatic. Anterior protrusion of lacrimal gland was measured to be 6.4 ± 1.2 mm (range, 5-10 mm) from the orbital rim. Incisional biopsy of the lacrimal gland was obtained in 10 patients (50%). Nine biopsies showed mild chronic inflammation and one revealed only normal lacrimal gland tissue. Postoperative course was uncomplicated in 15 patients (75%), with mild symptoms in the others and only one instance of mild unilateral recurrence of lacrimal gland prolapse.Conclusions: Reposition of a prolapsed lacrimal gland is a safe and effective adjunctive procedure in upper blepharoplasty, with minimal complications and acceptable postoperative outcome. Prolapsed lacrimal glands showed mild inflammation which could be due to repetitious movements of a lax gland, although various other etiologies can be involved.

RESUMO

Solitary or isolated neurofibroma is uncommonly observed in the orbit. Neurofibromas typically involve peripheral nerves and occasionally the cranial nerves. A 29-year-old man presented with recent onset left eye proptosis and exotropia. Physical examination was positive for hyperpigmented lesions of the ipsilateral ocular surface and hard palate. Imaging revealed an infiltrative orbital mass with extension through superior orbital fissure into the brain. There was also bone defect of greater sphenoid wing. Medial orbitotomy was performed to obtain biopsies of the orbital mass and the pigmented ocular surface lesions. Histopathologic diagnosis of neurofibroma was confirmed for the former and melanocytoma for the latter. His symptoms and examinations remained stable during the follow up. This case is unique due to several features, including extensive intracerebral spread of orbital neurofibroma in a patient without definite diagnosis of neurofibromatosis type 1 and association with ipsilateral ocular surface melanocytoma and palatal pigmented lesions. ABBREVIATIONS: CT: computed tomography; GFAP: glial fibrillary acid protein; MRI: magnetic resonance imaging; NF-1: neurofibromatosis type 1.

RESUMO

Phakomatous choristoma was first described as a distinct pathologic entity by Zimmerman in 1971. Report of only 26 cases of this tumor so far is an indicator of the rarity of phakomatous choristoma. We present a 4-month-old infant with an orbital mass beneath the right lower eyelid. Surgical excision was undertaken and the histopathologic findings of a dense fibrocollagenous stroma containing small to medium size islands and glandular-like structures surrounded by thick basement membrane and filled by amorphous eosinophilic material confirmed the diagnosis. Immunohistochemical study showed positive staining for S-100 and vimentin and negative staining for cytokeratins, glial fibrillary acidic protein, smooth muscle actin, synaptophysin, CD34, melan-A, and epithelial membrane antigen markers. This is the first patient with phakomatous choristoma presented from our country and the 27th reported case worldwide. Phakomatous choristoma is a rare, benign congenital tumor of lenticular anlage, almost always presenting in the medial lower eyelid and anterior orbit. Surgical excision is curative and allows precise diagnosis due to the unique histopathologic and immunostaining characteristics of this choristoma.

RESUMO

Neuroblastoma, a relatively common tumor in infants, is rarely present at birth. A solid mass is the typical appearance of this neoplasm, while cystic formation is uncommon. Congenital cystic neuroblastoma is extremely rare and no previous report exists of its occurrence in the orbit. A newborn girl was referred with an extremely large mass on the right side of her face on the third day of her life. Prenatal ultrasonography had revealed a large mass (80 × 80 mm) in the frontal area. MRI revealed a heterogeneous mass composed of cystic and solid, contrast-enhancing components. Excisional biopsy was successfully performed and histopathologic diagnosis of neuroblastoma was confirmed. Systemic workup was negative for involvement of other organs and levels of catecholamine metabolites of serum and urine (homovanillic acid and vanillylmandelic acid) were normal. Postoperative course was uneventful with complete healing of the anophthalmic socket and normal physical and mental growth and development of the infant. To our knowledge, this is the first report of congenital cystic neuroblastoma primarily arising in the orbit.

RESUMO

Hemangioendothelioma is rarely encountered in the orbit. We present a patient with a growing orbital mass for whom surgical excision was planned. Two previous attempts at removing the mass failed due to profuse bleeding. Endovascular embolization was performed before surgery to prevent massive hemorrhage. After embolization, retinal vascular accident (combined central retinal artery and vein occlusion) occurred. However, surgical excision (lateral orbitotomy and transcoronal craniotomy) was successful, and the vision improved postoperatively. Histopathologic examination and immunohistochemistry study confirmed the diagnosis of epithelioid hemangioendothelioma. The combined approach by a team of specialists, including an interventional radiologist performing preoperative embolization of the feeding vessel and joint surgery by a neurosurgeon and oculoplastic surgeon, was the key to the effective treatment of this vascular orbital neoplasm.

RESUMO

BACKGROUND: Synkinesis is a recognized complication following peripheral facial nerve paralysis. Different types of synkinesis have been described, with oral-ocular and ocular-oral synkinesis being the most common. Ocular-nasal synkinesis has been reported in two patients following cosmetic rhinoplasty. However, synkinesis between the orbicularis oculi and procerus muscles has not been reported by now. METHODS: This is an interventional case report. RESULTS: Two women, aged 42 and 37 years, presented with unilateral contraction of the medial eyebrow muscles (procerus) with spontaneous or voluntary blinking, 4 and 5 months after cosmetic rhinoplasty, respectively. Both were successfully treated with injection of botulinum toxin A. CONCLUSIONS: Surgical trauma is inevitable during every procedure, including rhinoplasty, and may damage the fine structures including branches of the facial nerve innervating the muscles. Gentle tissue handling may minimize iatrogenic injury to the fine motor branches of the facial nerve and prevent subsequent aberrant innervation and synkinesis. Botulinum toxin A injection can effectively, yet temporarily, resolve the unintentional contractions and provide significant patient comfort.

RESUMO

Purpose: To measure alterations in orbital blood flow parameters using color Doppler imaging (CDI) before and after orbital decompression in patients with moderate to severe thyroid eye disease (TED). Methods: Resistance index (RI) and maximum and minimum velocity of ophthalmic artery (OA), superior ophthalmic vein (SOV), and central retinal artery (CRA) of 24 eyes (14 patients) with TED were measured before and at least 3 months after cosmetic orbital decompression procedure (single or double walls) using CDI. Complete eye examination was performed to define the severity (EUGOGO classification) and activity (clinical activity score) of TED. Results: Median OA (p = 0.003) and CRA (p = 0.001) resistance indices were significantly reduced postoperatively. Significant differences were found in maximum (p = 0.001) and minimum (p = 0.014) velocity of SOV before and after surgery. While a significant decrease in exophthalmometry was observed after the orbital decompression (p = 0.031), intraocular pressure changes were not significant (p = 0.182). Conclusion: Orbital decompression procedure led to a significant reduction of RI in both CRA and OA in patients with TED.

RESUMO

PURPOSE: To report a case of intraoperative rupture of inferior rectus muscle, which was retrieved and later successfully transposed for management of sixth nerve palsy. METHODS: Case report. RESULTS: A 36-year-old woman presented with traumatic right sixth nerve palsy and esotropia following a car accident five years earlier. During the originally planned vertical transposition surgery, the inferior rectus muscle snapped, but was retrieved and resutured to the sclera 3 mm posterior to the original insertion. After a few months, the second attempt of transposition of vertical recti (including the previously snapped and reattached inferior rectus) was successful, and the patient achieved satisfactory postoperative alignment. CONCLUSIONS: Intraoperative rupture of an extraocular muscles is a rare and serious complication encountered during strabismus surgery. However, if successfully retrieved, this muscle has still the chance of future re-operation.

RESUMO

PURPOSE: To determine the rate of success of small-incision levator resection technique for correction of congenital ptosis. METHODS: Patients with congenital ptosis who were candidates for levator resection were enrolled if their levator function was not poor (< 5 mm). Incisions were made on upper eyelid crease with a length of 10-12 mm. After resection of adequate length of levator muscle, two sutures were used to fix it to tarsal plate. Sliding the incision to medial and lateral sides provided a wider field of access to allow the surgeon to place the sutures above nasal and temporal borders of limbus. Success was defined as margin reflex distance-1 (MRD-1) ≥ 3 mm and inter-eyelid difference of MRD-1 less than 1 mm, which was considered excellent if inter-eyelid difference was < 0.5 mm and good if the latter parameter was between 0.5 and 1 mm. RESULTS: Fifty eyes of 47 congenital ptosis cases (16 males and 31 females) were included. Average age was 21.7 ± 9.7 years (range, 3-44 years). Mean preoperative levator function and MRD-1 were 11.26 ± 2.79 and 1.78 ± 0.92 mm, respectively, while postoperative MRD-1 increased to 3.95 ± 0.82 mm (P < 0.001). The result was failure (undercorrection) in 12 cases (25.5%), good in 9 patients (19.2%), and excellent in 26 cases (55.3%). CONCLUSIONS: Small-incision levator resection has previously been studied for correction of aponeurotic ptosis and proved to yield successful outcome. The findings of this study suggest that small-incision technique can be effectively used in correction of congenital ptosis, as well.

RESUMO

BACKGROUND: Hemangiopericytoma and solitary fibrous tumor are considered related variants on the same spectrum and both may essentially be the same tumor. They are infrequently encountered in the orbital region while the zygomatic bone is an extremely rare location for these neoplasms to occur. CASE PRESENTATION: A 14-year-old boy presented with complaint of deformity of left infraorbital area and a firm, regular mass in the region. Orbital CT scan revealed a well-defined round isodense intraosseous lesion in the lowermost portion of the lateral orbital wall (zygomatic bone), expanding the bone and protruding anteriorly and medially. MRI showed the mass to be heterogenous and strongly enhancing with contrast medium. Inferior transconjunctival orbitotomy was performed and the mass was removed. The histopathologic examination and immunohistochemistry staining results (positive for CD34, CD31 and smooth muscle actin, but negative for CD99, S100, B-cell lymphoma 2 (bcl-2) and desmin) confirmed the diagnosis of hemangiopericytoma. The postoperative course was uneventful, with no evidence of recurrence after 5 years follow up. CONCLUSIONS: This case represents the second hemangiopericytoma reported in the zygomatic bone. Although extremely rare, hemangiopericytoma/solitary fibrous tumor might be considered in the differential diagnosis of intraosseous lesions of the orbital and zygomatic region.

RESUMO

PURPOSE: The aim of this study was to determine the agreement between Pentacam HR (Scheimpflug imaging, Oculus) and Orbscan II (scanning slit topography, Bausch and Lomb) in measuring corneal parameters after photorefractive keratectomy (PRK) for hyperopia. METHODS: In this prospective cross-sectional study, 38 hyperopic eyes undergoing PRK were examined before refractive surgery and 8 to 10 months postoperatively using Pentacam HR and Orbscan II. Ultrasound (US) pachymetry was also used to measure central corneal thickness (CCT). The radius of anterior (A-) and posterior (P-) best-fit sphere size (BFS), central elevation (CE), and anterior maximum tangential power in 3 mm (TG3) and 3-5 mm (TG5) zones, anterior chamber depth (ACD), and central corneal thickness (CCT) were collected and used in the analyses. To study the agreement between the measurements made by the two devices, the method described by Bland and Altman was used and the 95% limits of agreement were calculated. RESULTS: The 95% limits of agreement show reasonable agreement between the measurements by Pentacam HR and Orbscan II for A-BFS, P-BFS, A-TG3, and CCT, but not for A-CE, P-CE, A-TG5, or ACD. CCT values obtained by both Pentacam HR and Orbscan II correlated well with the values determined by US pachymetry. CONCLUSION: Pentacam HR and Orbscan II after PRK for hyperopia show reasonable agreement for determining A-BFS, P-BFS, A-TG3, and CCT, but not for A-CE, P-CE, A-TG5, or ACD. CCT measurements with Pentacam HR have reasonable agreement with US pachymetry.

RESUMO

PURPOSE: To compare the outcome of trabeculectomy using adjunctive intracameral bevacizumab versus intraoperative mitomycin C (MMC). MATERIALS AND METHODS: In this double-blind, randomized clinical trial 87 eyes of 87 patients with primary open-angle or pseudoexfoliation glaucoma were assigned to each treatment group (44 cases received 1.25 mg intracameral bevacizumab at the end of operation and in 43 cases MMC was applied during surgery). Success was defined as intraocular pressure (IOP) between 6 and 21 mm Hg and at least 30% IOP drop with (qualified) or without (complete) glaucoma medications without additional glaucoma surgery. RESULTS: The follow-up time was 17.12±2.58 months in the bevacizumab group and 17.23±2.42 months in the MMC group (P=0.845). The preoperative IOP was 29.17±3.94 and 28.8±4.08 mm Hg in the bevacizumab and MMC groups, respectively (P=0.689). Last visit IOP was 17.41±3.11 mm Hg in the bevacizumab group and 15.34±3.62 mm Hg in the MMC group (P<0.009). Compared with baseline, IOP drop at last visit was 11.76±5.51 and 13.43±5.92 in the bevacizumab and MMC groups, respectively (P=0.207). At last visit, complete success was achieved in 25 cases (61%) of bevacizumab group and 23 cases (66%) of MMC group (P=0.669). Early filtering bleb leak was more prevalent in bevacizumab group (29% vs. 11%). CONCLUSIONS: A single 1.25 mg dose of intracameral bevacizumab improves the success of trabeculectomy comparable with MMC; however, it increases the risk of early filtering bleb leakage.

RESUMO

PURPOSE: To investigate the outcome of trabeculectomy with or without adjunctive intracameral bevacizumab. MATERIALS AND METHODS: In this prospective, double-blind, randomized clinical trial, 71 patients with primary open-angle or pseudoexfoliation glaucoma were randomly assigned to receive either 1.25 mg intracameral bevacizumab (n=36) or balanced salt solution as placebo (n=35) at the end of trabeculectomy. Success was defined as at least a 30% drop in intraocular pressure (IOP) compared with baseline values and an IOP between 6 and 21 mm Hg at the last postoperative visit with (qualified) or without (complete) glaucoma medications. RESULTS: Thirty-two patients in bevacizumab group and 33 in placebo group completed a mean follow-up of 10.7±2.1 and 10.5±2.5 months, respectively (P=0.731). The mean preoperative IOP was 28.25±5.64 and 29.11±4.65 mm Hg in the bevacizumab and placebo groups, respectively (P=0.485). Last visit IOP was 14.5±3.7 mm Hg in the bevacizumab group and 18.55±3.64 mm Hg in the placebo group (P<0.001). At last visit, complete success was achieved in 26 cases (81.3%) of bevacizumab group and 16 cases (48.5%) of placebo group (P<0.006). Filtering bleb leak during the first postoperative month was seen in 11 (34%) and in 3 (9%) cases of bevacizumab and placebo groups, respectively (P=0.013). CONCLUSIONS: A single 1.25 mg dose of intracameral bevacizumab significantly improves the success of trabeculectomy; however, it increases the risk of early filtering bleb leakage.

RESUMO

PURPOSE: To report a case of primary acquired melanosis (PAM) successfully treated with combined topical mitomycin C and interferon-α2b. CASE REPORT: A 75-year-old man presented with an extensive unilateral pigmented lesion involving 360° of the bulbar conjunctiva, extending to the fornices and palpebral conjunctiva. Map biopsy confirmed PAM with local atypia. Treatment was initiated with mitomycin C 0.04% eye drops for two courses. Although the lesion markedly responded to the treatment, residual lesions justified further therapy. To avoid ocular surface toxicity induced by excessive mitomycin C exposure, interferon-α2b eye drops were started and continued for 6 months. The pigmented lesion almost completely disappeared and no significant complication or recurrence was observed for 24 months. CONCLUSION: Combination therapy using mitomycin C and interferon-α2b for PAM with atypia may be recommended as an effective treatment modality, avoiding the ocular surface toxicity due to excessive mitomycin C exposure.

RESUMO

PURPOSE: To evaluate the visual and refractive outcomes, endothelial cell count (ECC), ocular surface changes, corneal aberrations, and biomechanical profile changes after femtosecond laser-assisted anterior lamellar keratoplasty surgery for superficial corneal scars. SETTING: Farabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran. DESIGN: Prospective case series. METHODS: Patients with superficial corneal scars had femtosecond laser-assisted anterior lamellar keratoplasty. Visual and refractive results, ECC, ocular surface changes, corneal aberrations, and biomechanical profiles were assessed preoperatively and for 1 year postoperatively. RESULTS: Nineteen eyes (19 patients) were evaluated. A significant decline occurred in refractive astigmatism and corneal astigmatism after 1 year. There was a nonsignificant reduction in corneal hysteresis and the corneal resistance factor from preoperatively to 1 year postoperatively. The corneal-compensated intraocular pressure (IOP) and Goldmann-correlated IOP increased during the follow-up; the increase was not significant. A statistically insignificant reduction in the root mean square for trefoil and spherical aberrations occurred between 1 month and 1 year postoperatively (P=.1 and P=.4, respectively). The decreases in primary coma and total higher-order aberrations approached significance (P=.08 and P=.07, respectively). There were no significant changes in the central corneal thickness, ECC, or ocular surface parameters. No intraoperative complications occurred. CONCLUSION: Femtosecond laser-assisted anterior lamellar keratoplasty was an efficient and safe procedure for improving the quality of vision in patients with anterior corneal pathology, and the results remained stable during the 1-year follow-up.
