Purpose To study the demographic profile and factors associated with visual outcome in patients with indirect traumatic optic neuropathy. Methods A retrospective study of patients admitted with indirect traumatic optic neuropathy, in a tertiary care centre in South India, from February 2016 to February 2018 was conducted. Patients with bony impingement on the optic nerve were treated with endoscopic surgical decompression and the rest were treated with low dose steroids. Visual acuity was assessed at presentation, 2 weeks and 3 months. Results The mean age of the patients was 31.6 years (13-75 years). 19(90.4%) patients were male and road traffic accident (95.23%) was the most common cause of injury. Mean time of presentation was 3.6 hours ( 1-7 hours) Vision at presentation was perception of light and above in 8(3.1%) and no perception of Light in 13(61.9%) patients. Visual improvement was seen in 4 out of 18 patients (22.2%) in the steroid group and 1 out of 3 patients (33.3%) in the surgery group. Visual acuity at presentation was significantly associated with final visual outcome (P=0.047). Conclusion Our study demonstrated that visual acuity at presentation was the only factor associated with final vision, irrespective of associated injuries and treatment modalities.

Objective. To investigate the clinical characteristics and factors affecting visual outcome in patients with intraocular foreign bodies (IOFBs) and determine the risk factors for the development of endophthalmitis. Study Design. A retrospective case-series study design was adopted. Subjects. In total, 242 patients (242 eyes) who were hospitalized and underwent surgical treatment for IOFB at the Second Hospital of Hebei Medical University between January 1, 2008, and December 31, 2019, were included. Methods. The demographic data, cause of injury, characteristics of IOFBs, postinjury ocular manifestations, and surgical details of the subjects were collected, and the factors affecting visual outcome and endophthalmitis development were analyzed. Results. The most common cause of IOFBs was the propulsion of foreign bodies into the eye due to hammering (149 cases, 61.57%), followed by foreign body penetration (57 cases, 23.55%). Most of the subjects were young adult men who sustained injuries in the work environment. Poorer visual outcomes were found in subjects with initial presenting symptoms visual acuity (PVA) < 0.1, largest IOFB diameter ≥ 3 mm, IOFBs located in the posterior segment, wound length > 5 mm, entrance wound length larger than the largest IOFB diameter, concomitant retinal detachment, concomitant vitreous hemorrhage, concomitant endophthalmitis, and concomitant proliferative vitreoretinopathy (PVR). Factors related to the development of endophthalmitis included lens capsule rupture, time of stage 1 repair surgery ≥ 24 h after trauma, removal of IOFBs ≥ 24 h after trauma, and nonadministration of intravitreal antibiotic injection. Conclusion. Among patients with IOFBs, initial PVA < 0.1, entrance wound length larger than the largest IOFB diameter, concomitant endophthalmitis, and concomitant PVR were risk factors for poor visual outcomes. Lens capsule rupture was a risk factor for endophthalmitis development, and the administration of intravitreal antibiotic injection was a protective factor against endophthalmitis development.

ABSTRACT Objective To assess the visual outcome after endoscopic, endonasal trans-ethmo-sphenoidal optic nerve decompression in patients with traumatic optic neuropathy. Materials and methods Prospective study, at tertiary referral center. Study included 12 patients with post-traumatic indirect unilateral optic nerve injury, not responding to medical management with methylprednisolone. These patients underwent optic nerve decompression via trans-ethmo-sphenoidal route using nasal endoscope. Main outcome measure was postoperative visual acuity. Results Out of the 12 cases of traumatic optic neuropathy (TON) operated upon, nine had good visual outcome. Conclusion The endoscopic endonasal trans-sphenoidal approach can decompress the traumatized and swollen optic nerve with excellent visualization of the orbital apex and optic canal, without the morbidity associated with brain retraction as in the conventional transcranial decompression.

Background Non-arteritic ischemic optic neuropathy (NAION) is the most common acute optic neuropathy over the age of 50 years. NAION is commonly associated with systemic vascular risk factors (diabetes, hypertension, hyperlipidemia) and small cup-to-disc-ratio. We have assessed the prevalence risk factors of NAION and the visual outcome in patients referred to a tertiary ophthalmology center in Kuwait. Materials and methods A retrospective review of new cases of NAION presenting within 2 weeks of onset were included and baseline clinical and demographics characteristic were determined. The prevalence of risk factors and the visual outcome (change in logMAR visual acuity, mean deviation of visual field) was compared between young NAION patients (below 50 years of age) and older NAION patients (over 50 years of age). The odds ratio of a final favorable visual outcome (visual acuity 20/40 or better) by age category was determined. Results Seventy-eight eyes of 78 patients with recent onset NAION were included in the study. The most prevalent risk factors for NAION in our subjects were diabetes (64.1%), small cup-to-disc ratio (61.5%), hyperlipidemia (51.3%) and hypertension (38.5%). Young NAION patients had better final logMAR visual acuity (0.55 +- 0.57) then older NAION patients (0.9 +- 0.73), (p = 0.03). Furthermore, young NAION patients were 2.8 times more likely to have a final visual acuity of 20/40 or better than older NAION patients, odds ratio (OR), 2.87; 95% confidence interval (CI), 1.12–7.40, Chi-square p-value = 0.03). Conclusion There is a high prevalence of systemic vascular risk factors and small cup-to-disc ratio in NAION patients referred to our center across different age groups (below and above 50 years). Patients below the age of 50 years with NAION are more likely to have a final visual acuity of 20/40 or better than NAION patients above the age of 50 years.
