Evaluation of Ocular Trauma Score and risk factors to predict evisceration or enucleation in open globe injuries.

PURPOSE: The aim of this study was to investigate the predictive factors for evisceration or enucleation surgery after open globe injury (OGI) and to investigate the effectiveness of the ocular trauma score (OTS) in predicting the outcome. METHOD: Data from 380 patients who underwent OGI repair were retrospectively analyzed. The eyes of 31 patients who underwent evisceration or enucleation after OGI repair and who were followed up for at least 6 months were included in the study. Demographic characteristics, presence of rupture, penetrating injury, endophthalmitis, retinal detachment and afferent pupillary defect were evaluated and OTS was calculated. The etiology of OGI, the interval between OGI repair and evisceration, the presence of eyelid and canalicular laceration, orbital fractures, prolapsed choroidal tissue, and the presence of foreign bodies were also analyzed. The size of the sphere after evisceration/enucleation, the need for revision surgery and the time to revision surgery were evaluated. RESULTS: Of the 380 patients, 31 (8.15%) underwent evisceration or enucleation after OGI. 19 of 31 patients underwent evisceration after primary repair of OGI, 10 patients underwent evisceration without OGI repair; 1 patient underwent enucleation after OGI repair and 1 patient underwent enucleation without OGI repair. The mean OTS was 37.95 in the group with evisceration/enucleation after OGI repair and 29.55 in the group without repair. The mean interval between OGI and evisceration was 2.4±5.9 (0-13) months. The etiology of 10 (32.2%) OGIs were traffic accidents, 9 (29%) were penetrating trauma with cutting or penetrating instruments, 8 (25.8%) were blunt trauma, and 4 (12.9%) were gunshot wounds. The mean follow-up time was 38.9±23.59 (6-72) months. There was no significant difference in OTS according to age, gender, affected side and etiology. Although OTS was lower in patients with additional injuries than in those without, the difference not statistically significant. There was a statistically significant decrease in OTS from zone 1 (cornea and limbus) to zone 3 (posterior to 5mm from the limbus) (P=0.015, r=-0.433). CONCLUSION: The decision and consent for evisceration/enucleation after an open globe injury is very difficult for both patients and physicians. We believe that the presence of the injury in zone 3 and the presence of rupture are poor prognostic factors and that an OTS below 49 could be a risk factor for evisceration/enucleation. In conclusion, the OTS could be an objective parameter that provides an objective idea of visual rehabilitation and prognosis and helps in decision making for further surgery.

A rare case of pediatric ptosis: Coexistence of giant intracranial arachnoid cyst and facial asymmetry.

BACKGROUND: Intracranial arachnoid cysts are cystic congenital malformations, filled with cerebrospinal fluid (CSF) originating from the arachnoid membrane. Generally, giant arachnoid cysts present with symptoms related to increased intracranial pressure, hydrocephalus or cognitive disorders, endocrinological problems, growth retardation, seizures, headache, and nonspecific symptoms such as dizziness. They can be detected by imaging when they become symptomatic or incidentally in childhood and adulthood. Our case was referred to our clinic because of ptosis and facial asymmetry found on examination. Subsequently, a intracranial giant arachnoid cyst was found incidentally on cranial computed tomography (CT). CASE: In an 18-month-old male infant admitted with ptosis, left frontal bulging and a dystopic globe with ptosis of the left upper lid were noted. The left half of the facial region and the left nostril also appeared to be asymmetrically elongated downward relative to the right. Fundus examination revealed an optic disc coloboma in the left eye. On general physical examination, he was unable to walk. A giant fronto-temporo-parietal arachnoid cyst with the cerebral parenchyma shifted 2cm to the right of the midline was observed on cranial CT. After a cysto-peritoneal shunt was performed, the physical appearance of our patient returned to normal. CONCLUSION: Ptosis cases accompanied by abnormalities such as optic disc coloboma and facial asymmetry should be evaluated for possible midline defects and intracranial pathologies prior to eyelid surgery.

Nonarteritic anterior ischemic optic neuropathy in young patients.

PURPOSE: To determine and report the demographic and clinical features of patients younger than 50 years with nonarteritic anterior ischemic optic neuropathy (NAION). MATERIAL AND METHODS: In this comparative study, we retrospectively reviewed the medical records of 120 patients with NAION. Patients were divided into two groups according to their age; in group I, 44 patients were younger than 50 years, and in group II, 76 patients were older than 50 years. RESULTS: The gender distribution was similar in both main groups. Involvement was bilateral in 50% and 26.3% of patients, respectively (P<0.0001). Diabetes mellitus was present in 63.6% of patients in group I and 47.3% of patients in group II (P=0.009). We found hypertension as a frequent risk factor in group II (P=0.019). There was no significant difference in the initial and final visual acuities of patients between the two groups. Both groups had a significantly thinner peripapillary nerve fiber layer (RNFL) in every quadrant. The relative loss was greatest in the superior quadrant in both groups. We generally observed inferior altitudinal defect and superior RNFL thinning in two groups. In group I, 30 eyes (68.1%) demonstrated angiographically diffuse optic disc filling delay of ≥5seconds after choroidal filling confirming ischemia, and 14 (31.8%) eyes with segmental optic disc filling delay. In group II, diffuse optic disc filling delay was seen in 56 of 76 (73.6%) eyes. Segmental optic disc filling delay was present in 20 eyes (26.3%). There was no significant difference in angiographic findings between the two groups (P=0.67). CONCLUSION: We observed that age did not play a significant role in prognosis of NAION. Diabetes is an increased risk for NAION in the young age group, and HT for NAION in the older group. Fellow eye involvement is more frequent in young patients. These patients should be followed closely.
