Implant materials for orbital surgery are mainly used during orbital traumatic deformity-eliminating operations, postenucleation stump plasty, evisceration, and anophthalmic syndrome correction. There are currently a lot of biological and artificial implant materials, but there is no universal material to correct all types of defects and this makes surgeons use a great quantity of reparative procedures and techniques and scientists continue to search for more suitable implant materials. This paper reviews the currently available materials used in orbital surgery in Russia and foreign countries.

The paper reviews specific complications of conventional peeling of the internal limiting membrane (ILM) of the retina in various macular pathologies. It also considers the promising directions of development of ILM surgery, including enzymatic lysis and femtosecond laser ablation of the ILM.

The paper gives data of computed tomography in 100 patients (148 orbits) with edematous exophthalmos (lipogenic and mixed types). There is a relationship of the higher degree of exophthalmos to the increased orbital soft tissue contents. A procedure is described for the individual calculation of the amount of removed orbital fat during compressive operations, which considers both the individual features of the anatomic structure and existing exophthalmos.

The paper lays down the basic principles of ophthalmoplastic treatment on the basis of an analysis of the results of treatment and follow-ups of 2300 patients aged 6 months to 18 years who have abnormalities of the orbit and appendages of the eye. Emphasis is laid on the preference of methods for plastic repair, using local tissues, and free autologous grafting of the skin and mucosa. A soft material that is to be easy grown through, such as Carbotextim-carbonic felt, is recommended when contour plastic repair of the orbit is required. For hanging, a mersilene mesh should be employed in case of blepharoptosis. To achieve the better cosmetic results, it is better to operate at the age of more than 4 years; however, treatment should be initiated at the age of 1 year when there are available functional indications (symblepharon, ablepharia, or cryptophthalmus).

The paper considers the armament development ultimately resulting in the predominance of using minor blasting assemblies and accordingly to a drastic prevalence (as high as 80%) of mine explosion injuries among other battle injuries to the eye. The particular severity of these injuries requires their efficient subdivision into types and severity, which is alleviated by the introduction of a new classification of mechanical injuries into the eyeball. It is obligatory for each ophthalmologist to know this classification. It is the ophthalomologist who may be the first specialist to start rendering an aid to the victim. In terms of the highest level of development of modern ophthalmological diagnosis and intraocular eye surgery, delivery of a patient to a specialized eye traumatological center where he/she will be given a comprehensive aid, including an intraocular one, in 3-7 days rather than the promptest surgical debridement (generally as just wound closure) is a master link in obviating the losses associated with eye injury. There is evidence that the same interregional centers as the army centers that have operated in Kabul and Rostov-on-Don should be set up preferably on the basis of multidisciplinary hospitals in the civil health care system. They could become an original testing area for researches of explosive injuries to the eye and a source of materials for making the centralized national register of eye injury.

The present paper generalizes the tactical principles of the examination and treatment of patients with orbital fractures. The clinical signs of a fracture are evaluated, with emphasis laid on the significant and insignificant symptoms. Routine X-ray study is regarded as an inadequate diagnostic technique, computed tomography is presented as a basic procedure for detecting and detailing the specific features of the fracture. The cases (n = 161) are divided into 5 groups according to the types of fracture. The treatment sequence is defined, by taking into account the severity of injury. The time of reparative operations (early or late) is recommended in terms of the risk for ocular dysfunction. The principles of reparative and compensatory surgical techniques for different types of injuries, mainly by applying bony autografts and Carbotextim, are given.

The paper analyzes the diagnostic value of computed tomography (CT) in posttraumatic lesion of the eye socket, ball, and appendage and identifies the basic groups of patients in whom CT is an essential study. In 2004, the Department of Traumatology, Reconstructive Surgery, and Eye Prosthesis, Helmholtz Research Institute of Eye Diseases, performed CT in 323 patients (18.2% of the inpatients and 3.4% of the outpatients). Analyzing all CT images identified the basic groups of patients in whom this study was essential. The CT scans characterizing examples from each group of patients are given. The studies could extend indications in patients with posttraumatic lesion of the eye and orbital area for CT. The latter is an important and essential study in patients with traumatic pathology of the eye with multiple and hard-to-reach foreign bodies and with trauma of the soft and osseous structures of the orbit, which makes it possible to determine not only the possibility, but also pattern and scope of a surgical intervention and to assess its long-term result.

The paper deals with the analysis of the outcome of severe eye contusion in scleral ruptures that are subject to none or inadequate debridement. In 2004, a group of 85 patients undergone enucleation due to severe posttraumatic changes was examined to analyze the outcomes of misdiagnosis of ruptures of the scleral capsule of the eye in its contusions and penetrating wounds. Examination of the eyeball after its removal revealed different defects of the optic scleral capsule in 6 (8.2%) cases of the 85 patients undergone enucleation. Each case pointing to the undiagnosed pathology of the eye during primary debridement and surgical treatment of these patients or to the partial debridement of scleral wounds is noteworthy. It should be noted that a primary care involving debridement was delivered to virtually all patients in different ophthalmological facilities. The paper gives a detailed account of each case, by describing its history data, the state of the eye, the performed studies and operation, and presents photos demonstrating each case. In eye contusion, it is necessary to adequately evaluate its severity and to reveal the whole complex of injuries and also to pay attention to the quality of debridement of wounds since adequate containment of a wound of the eye and adaptation of its edges can preserve the eye as an organ in most given cases.

The paper presents an analysis of traumas of the orbit combined with craniocerebral trauma in children made according to data obtained at the eye microsurgery department, Morozov's Pediatric City Clinical Hospital. Fractures of the lower orbit wall account for around 70% of all orbit fractures; clinical signs of fractures of the lower orbit wall are defined; computer tomography is shown to be the most informative diagnostic tool. The paper contains indications for plasty of the lower orbit wall. Materials used in orbitoplasty are comparatively analyzed. The use of demineralized osseous implants is preferential.

The use of a metallic suture in eye microsurgery is described in the paper. The metallic suture made from a 0.05-0.05 mm vanadic stainless steel wire (corresponding to 8:0) was applied in 1202 cataract extractions, penetrating injuries, antiglaucomatous surgeries and in removal of pterygium at the medical-and-sanitary facility of steel works in the town of Bokaro (India). The observation period ranged, on the average, from 3 months to 3 years. There were no complications during the procedure of applying the suture. However, it caused a minor response in the ocular tissues during the early postoperative period. Small bullae were observed in the corneal surface near the suture in 7 cases (0.58%), which disappeared spontaneously in 3-4 days. Irritations inflicted by the suture ends were registered in 2.58% of cases (31 patients). The mean postoperative astigmatism was, 3 months after surgery, 1.65 diopters. The sutures were removed in 132 cases (10.98%), including in 16 patients with irritation, and in 116 patients for the purpose of correcting a high astigmatism. The share of patients with a visual acuity of 0.5 and higher was, in one week, 43.59% and went up, one month later, to 78.20%. The suture was well tolerated by patients, it was quickly covered by the corneal epithelium, there was no rejection and it can be easily manufactured. The suture is sterilized by routine techniques without need for any extra treatment before use; it is a reactive, biologically inactive, efficient, convenient and causes minimal operative and postoperative complications.
