Open globe ocular trauma: functional outcome of eyes with no light perception at initial presentation.

Purpose: To evaluate characteristics and prognostic factors for functional success in eyes that present with no light perception (NLP) after open globe trauma. Methods: The medical records of all subjects presenting to a single university referral center with visual acuity (VA) of NLP after sustaining an open globe eye injury from January 1, 2001, through June 30, 2010, were retrospectively analyzed to determine epidemiologic and clinical factors associated with visual outcomes. Results: Of the 73 NLP eyes (73 patients) that underwent primary repair and were included in the study, final VA was 20/100 in 1 eye (1%), counting fingers in 2 eyes (3%), hand motion in 9 eyes (12%), light perception in 5 eyes (7%), and NLP in 56 eyes (77%). Recovery of some vision on postoperative Day 1, pars plana vitrectomy operation, and Zone 2 injury were significantly associated with an improvement in final VA. Zone 3 injuries were the most likely to result in NLP final VA, although this difference was not statistically significant. Conclusion: Visual recovery to light perception or better on postoperative Day 1 increases the likelihood of having a long-term improvement in VA. Pars plana vitrectomy may be beneficial in such eyes if posterior segment abnormalities are noted.

Characteristics, outcomes, and prognostic indicators of fall-related open globe injuries.

Purpose: To describe characteristics and outcomes of fall-related open globe (OG) injuries. Methods: A total of 602 patients (603 eyes) presenting with OG injuries were included. Among them, 85 wounds (85 patients) were fall-related, which were compared with the nonfall-related OG injuries (control group). Results: The mean patient age in the fall group was 65.8 years, which was higher than the control population (35.8 years; P < 0.001). Most of the fall-related injuries occurred in women (58.8%). The most common zone injured in both groups was Zone I (38.8% and 46% in the fall and control group, respectively). Compared with the control group, patients with fall-related OG injuries had a worse visual acuity on admission and at final visit (P < 0.001). The authors performed regression analysis to characterize factors associated with developing no light perception and need for enucleation. Injuries involving Zone III and presenting vision of no light perception were associated with a higher rate of no light perception. Similarly, patients presenting with no light perception were more likely to undergo enucleation, eventually. Conclusion: Fall-related OG injuries can lead to severe ocular morbidity especially in the elderly patients. They carry a worse visual prognosis compared with other injuries, which emphasizes on the importance of protective measures in this population.

Approach to Management of Eyes with no Light Perception after Open Globe Injury.

Loss of light perception (LP) after open globe injury (OGI) does not necessarily mean the patient will have permanent complete visual loss. Findings that seem to be associated reliably with permanent profound vision loss after OGI include optic nerve avulsion, optic nerve transection, and profound loss of intraocular contents, which can be identified with CT/MRI imaging albeit with varying degrees of confidence. Eyes with NLP after OGI that undergo successful primary repair with intact optic nerves may be considered for additional surgery, particularly if there is: (1) recovery of LP on the first day after primary repair; (2) treatable pathology underlying NLP status (e.g., extensive choroidal hemorrhage, dense vitreous and subretinal hemorrhage); (3) NLP in the fellow eye. We counsel patients that the chance of recovering ambulatory vision under these circumstances is very low (~5%).

Surgical Management and Outcome of Open Globe Injuries with Posterior Segment Complications: A 10-Year Review

ABSTRACT Purpose: To describe the characteristics, management, and outcomes of open globe injured (OGI) eyes that underwent pars plana vitrectomy (PPV) for posterior segment complications. Methods: Retrospective chart review of cases that underwent PPV for posterior segment complications associated with OGI between 2003-2012 at University Hospital, Newark, NJ. Results: 120 eyes were identified and classified as follows: “early retinal detachment (RD)” (within 30 days of OGI), 64 (53%) eyes; “delayed RD” (≥30 days after OGI), 30 (25%) eyes; and “no RD,” 26 (22%) eyes. Injuries included penetrating (39 (33%) eyes), rupture (60 (50%) eyes), and penetrating wounds with retained intraocular foreign body (21 (17%) eyes). Injuries in Zones I, II, and III were seen in 40 (35%) eyes), 38 (34%) eyes, and 35 (31%) eyes, respectively, with statistically different ocular trauma scores (p<0.01) associated with each zone of injury. Mean presenting and final logMAR VA were 2.20± 0.63 and 1.87 ±0.60, respectively (p<0.01), with a mean follow-up of 3.2 years. Final overall anatomic success after surgeries was 98% for early RD and 95% for delayed RD. Conclusion: Despite a high anatomic success rate, the overall functional success rate for eyes with posterior segment trauma that undergo PPV is poor and comparable to other studies.

Characteristics of open-globe eye injuries with respect to zone of injury.

Aims: To describe the demographics, characteristics and outcomes of open -globe injuries (OGI) with respect to zone of injury. Methods: Medical records of all patients presenting with OGIs to University Hospita l, Newark, NJ between January 2001 and December 2008 with a follow-up of at least 3 months were reviewed. Demographics, characteristics of the trauma and outcomes were compared with respect to the zone of injury; location of injury is confined to the corn ea and limbus in zone 1 (Z1), 5mm posterior to the limbus in zone 3 (Z3). Results:Of the 309 patients (310 eyes) identified, 228 (74%) were male. The mean age at presentationwas 35.3years (1-96). Meanfollow-up was 22.8 months (3-108 months). Most of the eyes presented with Z1 injury: 141 eyes (46%) Z1 injury, 83 (27%)Z2 and 86 (28%) Z3. Rupture was the most common type of injury in Z2 and Z3 injuries. Nineteen (86%) of 22 eyes with an intraocular fore ign body(IOFB) had a Z1 injury. 32 (42%) of 77 eyes with Z3 injury had no light perception (NLP) at presentation, compared with 9 (8%) of 119 Z1 and 13 (17%) of 78 Z2 -injured eyes. Four percent of Z1, 11% of Z2 and 18% of Z3-injured eyes had a final visi
