Periocular Desmoplastic Malignant Melanoma and Orbital Invasion With Uncontrollable Disease: A Case Report.

Primary orbital melanoma and metastatic cutaneous melanoma of the orbit are extremely rare. Desmoplastic melanoma (DM) is an infrequent variant of melanoma that can extend from a superficial location into deep tissues by neurotropic mechanisms. A 78-year-old male was referred to us with a periocular mixed malignant melanoma (spindle cell melanoma with desmoplastic reaction) in his left lower eyelid with uncontrollable disease (orbital and inferior orbital rim invasion) despite treatment.

Superior orbital fissure syndrome after deep lateral orbital wall decompression in Graves' ophthalmopathy.

Purpose: The superior orbital fissure contains cranial nerves III, IV, VI, and V1 with their three branches: frontal, lacrimal, and nasociliary. Superior orbital fissure syndrome (SOFS) is rare and can occur as a result of compression of these nerves due to trauma, bleeding, or inflammation in the retrobulbar space, but no cases of SOFS after deep lateral orbital wall decompression (DLOWD) have been reported. The aim of this paper is to describe this pathology, its possible causes, management, and outcome.

Advanced Periocular Basal Cell Carcinoma with Orbital Invasion: Update on Management and Treatment Advances.

Purpose: Basal cell carcinoma (BCC) is the most frequent malignant periocular tumor. It is associated with exposure to ultraviolet radiation, and its incidence is gradually increasing. It may occasionally display more aggressive behavior and result in orbital or intracranial invasion.

Orbital Solitary Fibrous Tumor: Four Case Reports-Clinical and Histopathological Features.

Purpose: To retrospectively describe the clinical characteristics, management, and outcomes of four cases of orbital solitary fibrous tumor (SFT). In one patient, we present an ultrasonic aspirator system for tumor removal.

Methods: Four patients with orbital SFT were selected: one patient with orbital SFT, another patient with frontal and ethmoidal SFT and orbital affectation with high rates of recurrence, the third patient with frontal lobe SFT and orbital invasion with multiple recurrences, and the fourth case with a history of craniopharyngioma surgery and SFT located on the orbital apex.

Localized Bilateral Superior and Inferior Orbital Neurofibroma in the Absence of Neurofibromatosis.

Localized or isolated neurofibromas are peripheral nerve sheath tumors. They are rare in the orbit and occur without a systemic neurofibromatosis. There are few cases of bilateral tumors reported but none affecting both supraorbital and infraorbital nerves.

Giant Cell Reparative Granuloma of the Orbit: Clinicopathological Characteristics and Treatment.

Giant cell reparative granuloma (GCRG) is a rare fibroosseous lesion uncommonly seen in the orbital area. Although benign, it is known to be recurrent and locally destructive. We report two cases of GCRG of the orbit.

Vitreociliary Block in a Patient With Uveitis and Previous Laser Posterior Capsulotomy.

Purpose: To report a case of vitreociliary block (VCB) six months after a laser posterior capsulotomy (LPC).

Case Report: A 25-year-old man with uveitis, retinal vasoproliferative tumor, cataract, and acute angle-closure glaucoma due to pupillary seclusion, which required laser iridotomies, implantation of an Ahmed valve, phacoemulsification, and LPC. Six months after capsulotomy, he presented a generalized flattening of the anterior chamber (AC) and ocular hypertension, with patent iridotomies.

Surgical removal of orbital tumors by orbital approach using ultrasonic surgical system SONOPET®.

Purpose: Orbital tumor surgery can be challenging when the tumor is located in a very narrow surgical field and close to important structures, such as nerves or extraocular muscles that can be damaged during surgery. Advances in technology and special surgical techniques help to avoid such damage. We describe our experience using SONOPET® ultrasonic surgical aspirator to remove 12 different orbital tumors that were difficult to treat due to their poorly defined borders, adhesions, or location.

Conjunctival Tarsal Actinic Keratosis Treated with Interferon Alfa-2b: A Rare Case Report and Literature Review.

Conjunctival neoplasia is one of the most frequent tumors in the eye. Actinic keratosis (AK) or solar keratosis is a precancerous lesion that is included with other epithelial tumors. This alteration does not break the basal membrane.

Orbital-Conjunctival-Eyelid Hemorrhage-Hematoma due to Inappropriate use of FFP2/NK95 Facial Mask in COVID-19.

A non-traumatic or spontaneous orbital hemorrhage (NTOH) is usually caused by the presence of an orbital mass, an inflammation, an infection, a bleeding disorder or those called idiopathic. This entity usually affects elderly adults and some risk factors can be identified. The NTOH normally acts like a benign and self-limited process, but attending to its anatomical pattern, may need specific management.

Evaluation of Anxiety Levels in Patients Undergoing Intravitreal Injections and Associated Risk Factors Related to the Disease.

Purpose: To analyze patients' anxiety levels using the Visual Analog Scale for Anxiety (VASA), in regard to intravitreal injection treatment and to determine possible associated risk factors related to the disease and treatment characteristics.

Methods: Cross-sectional observational study with consecutive sampling of patients who were going to receive an intravitreal injection. Subjects completed the VASA prior to the procedure, and afterwards, their data were collected from the electronic medical history.

Eyelid Eccrine Poroma: A Case Report and Review of Literature.

Poroma is a rare benign tumor of the epidermal sweat duct unit with predilection for the head and neck. Only six cases with eyelid location have been described in the literature (PubMed). A 34-year-old male presented with a single tumor on the left upper eyelid.

Iris Vascular Malformation with 360-Degree Iridocorneal Angle Affectation.

Vascular iris lesions are rare and can sometimes be associated to systemic vascular lesions. They usually cause spontaneous recurrent hyphema. The differential diagnosis should be considered primarily with iris rubeosis and with highly vascular tumors as iris melanoma.

Rhino-Orbito-Cerebral Mucormycosis: Two Cases with Amaurosis as Presentation, Medical Surgical Management and Follow-Up.

Mucormycosis is an infection caused by fungi to the class Zygomycetes that usually appears in immunosuppressed patients. Diagnostic confirmation is often delayed, with fatal prognosis in cases in which treatment is not rapidly established. We present two clinical cases of rhino-orbito-cerebral mucormycosis with an atypical presentation form, consisting of a unilateral complete sudden vision loss.

Deep Lateral Wall Partial Rim-Sparing Orbital Decompression with Ultrasonic Bone Removal for Treatment of Thyroid-Related Orbitopathy.

Purpose: To describe the results of thyroid-related orbitopathy (TRO) treated by ultrasonic deep lateral wall bony decompression with partial rim sparing (DLW-PRS).

Methods: A review was carried out, from January 2015 to September 2017, of all patients treated with ultrasonic DLW-PRS decompression using a SONOPET® (Stryker, Kalamazoo, MI, USA) ultrasonic aspirator, using a lateral, small triangle flap incision for access. The primary outcome was the change in proptosis (measured by the difference in Hertel exophthalmometry measurements).

Occult Orbital Injury with Dagger Fragment with Resulting Pneumocephalus.

Penetrating injuries of the cranium are relatively uncommon, only 0.4% of all head injuries. In patients with disturbed conscious level, an extensive examination should be performed in the emergency unit to rule out transorbital penetrating brain injury.

Herpetic ocular manifestations in a patient with GATA2 deficiency.

Specific genetic deficiencies are a rare cause that should be included in the diagnostic algorithm of disseminated herpetic lesions. The aim of this article is to describe the ocular herpetic manifestations in a rare genetic disorder called GATA2 deficiency. We present the clinical case of a 26-year-old male with dendritic ulcers in his cornea, marrow aplasia and idiopathic chronic lymphedema.

Nasal Cavity or Alveolar Paranasal Sinus Rhabdomyosarcoma with Orbital Extension in Adults: 2 Cases.

Alveolar rhabdomyosarcoma (RMS) has a predilection for the deep soft tissues of the extremities and mainly occurs in children. Although the tumor may originate in other sites, such as the nasal cavity or paranasal sinus, invasion of the orbit is unusual. We describe the clinicopathological features of 2 cases of alveolar RMS of the nasal cavity or paranasal sinus in adult patients with orbital extension.

A Second New Choroidal Osteoma in the Same Eye: Differences between Them with New Imaging Techniques.

The authors introduce a 42-year-old woman with a choroidal osteoma. After 10 years the patient presented a second choroidal osteoma in the same eye; this osteoma has been growing in the last years. New tests that were unavailable during the first diagnosis were performed such as Fundus Autofluorescence or Enhanced Depth Imaging-Optical Coherence Tomography (EDI-OCT).

Obstructive sleep apnea-hypopnea syndrome (OSAHS) and glaucomatous optic neuropathy.

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is becoming widely accepted as a risk factor for glaucoma. We discuss the proposed mechanism involved in the pathogenesis of glaucoma in OSAHS, and review the published data on the association between these two conditions, as well as papers regarding functional and structural tests related with glaucomatous damage. There is increasing evidence that the prevalence of glaucoma is higher in OSAHS patients, especially in those with severe disease with apnea-hypopnea index (AHI) >30, and also that sleep disorders may be more frequent in patients with glaucoma, especially in those with normal tension glaucoma (NTG).

Isolated tarso-conjunctival superior eyelid traumatic laceration.

To report a unusual case of an isolated traumatic stellated tarso-conjunctival laceration located in the upper left eyelid without eyelid margin involvement and with normal ocular examination. A 19 year-old male wounded by a bokken (wooden katana) while practicing a sham duel had an isolated eyelid tarso-conjunctival laceration, without any other eyelid layer damage, neither skin nor muscle. Treatment was conservative without suture, by means of compressive occlusion fixing the pieces of broken tarsus in the correct position.
