Review
Primary neural tumors of the orbit account for approximately 10% of all orbital tumors. Different tumor entities include meningiomas, optic nerve gliomas, neurofibromas, schwannomas, malignant peripheral nerve sheath tumors, and granular cell tumors. This review summarizes current concepts regarding epidemiology, clinical presentation, diagnosis, pathology, immunohistochemistry, prognosis, and treatment for neural tumors of the orbit based on the available literature.

Review
Keeping the eye is impossible, functionality is lost and aesthetic requirements are high. What do we do? Which approach is right? This is the dilemma we face whenenucleation or evisceration are unavoidable. The patient loses a sensory organ with a very important function and, at the same time, is faced with a major aesthetic defect, leading to significant anxiety. The purpose of this article is to describe the different reconstruction techniques for anophthalmic sockets. In preparing the anopthalmic socket for prosthesis fitting we have several options: dermis-fat graft with a very good biocompatibility, the Guthoff artificial implant, which provides better motility or the methyl methacrylate implant inside the muscle cone. Each option has advantages and disadvantages but the choice of technique should be adapted to the needs and expectations of the patient, taking into account both time and cost.

Fibrous histiocytomas (FHs) are mesenchymal tumors that may be benign or malignant. Ocular involvement by FHs is infrequent and primarily limited to the orbit. Rarely, FHs can also involve the conjunctiva and perilimbal area. We report the case of a 38-year-old male with lid, conjunctival, and neck FHs. The diagnosis was confirmed by histopathology.

Perforating injuries of the orbit involving the paranasal sinuses are uncommon. We report a case in which a large wooden foreign body lodged in the posterior orbit and maxillary sinus was surgically removed by a combined approach by ophthalmologists and ear, nose and throat surgeons.

Review
Orbital pathology often presents a diagnostic challenge to the reporting radiologist. The aetiology is protean, and clinical input is therefore often necessary to narrow the differential diagnosis. With this manuscript, we provide a pictorial review of adult ocular and orbital pathology.

BACKGROUND
Standard anthropometric methods applied to measurements of the skull differentials are laden with mistakes stemming from the way the measuring devices are built and from a lack of experience on the part of the researchers. To increase objectivity, digital imaging measurements via computer systems were introduced.
OBJECTIVES
The aim of this research was to assess the asymmetry of the male and female orbit with the application of the new graphic methods: raster graphics and vector graphics.
MATERIAL AND METHODS
The examination was conducted on 184 well-preserved skulls. The photos were taken by a digital camera with high definition. Orbit asymmetry was examined by determining the distance between the centers of gravity of both orbits and the frontal median line d1 and d2. Then angles α and β were appointed. They are defined as angles between the line that runs through craniometrical points mf and ek on the right side (angle α) and on the left side (angle β), and the frontal median line at their crossing point. Distances r2 and r1, which are allocated points between the frontal median lines (LPP), were also set.
RESULTS
Angles α and β were also analyzed while comparing the skulls of both genders. Statistically significant differences were only observed in male skulls. However, differences for both genders were noted in parameters d1 and d2. No statistically significant differences were discovered between men and women for parameters r1 and r2. The groups of women and men were merged, being treated as a population; which resulted in the conclusion that there are no statistically significant differences between these parameters.
CONCLUSIONS
The skull's asymmetry connected to gender and the asymmetry of the right and left sides of examined craniums can be used in criminal examinations as well as in facial reconstructive surgeries.

Review
Magnetic resonance imaging (MRI) is an eloquent, noninvasive, cross-sectional imaging modality that offers superior tissue characterization of orbital pathologies. The ophthalmologist needs to be aware of the advantages of MRI and its step-wise interpretation in liaison with a radiologist to optimize patient outcomes. In this review, we discuss the basic principles of MRI, some of the commonly used sequences and protocols, the anatomy of the orbit on MRI, and an approach to radiological interpretation.

Transnasal endoscopic orbital decompression is a viable alternative for external orbital decompression. Today, it can be performed due to the great development of endoscopic technology and specific endoscopic surgical instruments. It requires strong anatomic knowledge and skilled hands. We present our experience with endoscopic orbital decompression focusing on the surgical technique used in our department. The surgical maneuvers must be firm and gentle protecting the local risk elements and respecting the orbital content.

Review
BACKGROUND
The grease-guns injury is an uncommon injury to the orbit. We present the twelfth and thirteenth cases of grease-gun injury to the orbit to be reported in the English language literature since 1964. Here we discus and review the presentation, investigation, and treatment of this unusual trauma.
CASE PRESENTATION
Case 1 was a 29-year-old man who presented 1 day after a grease-gun injury of the left orbit with severe pain, marked periorbital swelling, and proptosis. Computed tomography (CT) revealed penetration of grease into his left orbit. Following surgical removal, proptosis decreased. The limitation of extraocular movement and loss of visual acuity to finger count was discovered after the initial surgery. Motility gradually returned. Visual acuity recovered after phacoemulsification, capsular tension ring and intraocular lens implantation for traumatic cataract and subluxation. Case 2 was a 6-year-old boy who was referred 2 months after a grease-gun injury for worsening swelling with sinus, necrosis and slight ptosis of the upper left eyelids. This is a case of orbital chronic inflammation from grease-gun injuries masquerading as orbital cellulitis. The imaging findings of CT and magnetic resonance imaging (MRI) are not typical. Surgical exploration and debridement was inevitable and actually relieved the symptoms.
CONCLUSIONS
Grease-gun injuries can damage the orbit in different degrees. Careful history inquiry and taking is important to establish the diagnosis. Imaging examinations using CT or MRI are helpful to determine depth of trauma and foreign bodies in the orbit at diagnosis. We suggest that surgical exploration and debridement is a key step in the management.

A 28-year-old male presented with a large conjunctival lobulated, nonpulsatile, red vascular lesion involving a large part of the temporal quadrant of the left globe. There was no proptosis or globe displacement, but the left eye abduction was limited. T2-weighted magnetic resonance imaging scan of the brain and orbit revealed an extensive contrast-enhancing lobulated lesion in the left half of the face involving the upper lip, cheek, oral cavity, extraconal space of left orbit, and nasal cavity. He underwent surgical excision of the conjunctival lesion with amniotic membrane reconstruction.
