Purpose To study the characteristics of Medicare beneficiaries hospitalized for ophthalmic conditions. Design Cross-sectional study. Methods The 2015 National Medicare 100% Inpatient Limited Dataset was analyzed to identify all patients with either an admitting or primary diagnosis for an ophthalmic condition using ICD-9-CM codes. All other hospitalized Medicare patients served for comparison. Comorbidities were calculated using the Elixhauser Comorbidity Index. Multivariable logistic regression was used to determine odds of primary ophthalmic hospitalization after controlling for patient characteristics and medical comorbidities. Results For 2015, there were a total of 13 152 Medicare patients with ocular hospitalizations compared to 6 621 005 patients with nonophthalmic events. Most ophthalmic patients were emergent admissions (73.19%) with routine discharges (75.50%) and low rates of inpatient mortality (0.62%). The top admitting diagnoses for nontraumatic and traumatic eye conditions were diplopia (11.69%) and closed fracture of the orbital floor (3.76%), respectively. Patients admitted for eye conditions were more likely to be younger, to be African American, and to have hypertension, valvular heart disease, diabetes, hypothyroidism, AIDS, lymphoma, solid tumor without metastasis, rheumatologic diseases, alcohol and drug abuse, psychoses, and depression compared to the general Medicare inpatient population. Conclusions Most inpatient admissions for US Medicare beneficiaries with primary ophthalmic diagnoses were for nontraumatic disorders of the eye and adnexa. Ophthalmic admissions were on average shorter in duration and had lower rates of inpatient mortality compared to nonophthalmic admissions. Patients admitted for eye conditions were more likely to have comorbidities such as hypertension, diabetes, and depression compared to the general Medicare inpatient population.

PURPOSE: To examine the potential for visual acuity loss, and its relation to extent and location of optic pathway gliomas in a cohort of children with neurofibromatosis type 1 studied with magnetic resonance imaging. METHODS: We reviewed the neuro-ophthalmologic records and brain/orbital magnetic resonance imaging scans for 43 consecutive pediatric patients with neurofibromatosis type 1 and optic pathway gliomas who were followed at the Children's Hospital of Philadelphia. The presence of visual loss, defined as abnormal visual acuity for age in one or both eyes, was determined. Optic pathway gliomas were classified by tumor extent and location according to involvement of the optic nerves, chiasm, and postchiasmal structures by magnetic resonance imaging. RESULTS: Involvement of the optic tracts and other postchiasmal structures at tumor diagnosis was associated with a significantly higher probability of visual acuity loss ( P = .048, chi-square test). Visual loss was noted in 20 of 43 patients (47%) at a median age of 4 years; however, three patients developed visual acuity loss for the first time during adolescence. CONCLUSIONS: In pediatric patients with neurofibromatosis type 1 and optic pathway gliomas, the likelihood of visual loss is dependent on the extent and location of the tumor by magnetic resonance imaging and is particularly associated with involvement of postchiasmal structures. Furthermore, older age during childhood (adolescence) does not preclude the occurrence of visual loss. Close follow-up beyond the early childhood years, particularly for those with postchiasmal tumor, is recommended.

Purpose To report the case of a 58-year-old man with sequential bilateral retrolaminar leukemic infiltration of the optic nerves who presented with normal-appearing optic nerves and no optic nerve enhancement. Design Interventional case report. Methods A 58-year-old man with chronic myelogenous leukemia (CML) developed progressive vision loss to no light perception in both eyes over four days. Results The patient received 14 doses of external beam irradiation and 10 cycles of intrathecal cytarabine. Despite treatment, he developed optic nerve pallor, and visual acuity remained no light perception in both eyes. Conclusions In a patient with leukemia, leukemic optic nerve infiltration may occur even with normal-appearing optic nerves and a normal magnetic resonance image. It is important to maintain a high clinical suspicion for optic nerve infiltration so that prompt local irradiation may be initiated.

Frequently, patients with lens laceration or traumatic cataract coincident with corneal laceration, or both, must undergo two separate procedures-primary repair of the corneal laceration and secondary lens removal with or without intraocular lens implantation. We performed simultaneous corneal laceration repair, extracapsular cataract extraction, and posterior chamber lens implantation in seven patients with lacerating ocular injuries who met inclusion criteria for this procedure. With average follow-up of 10 1/2 months, all seven patients achieved visual acuity of 20/40 or better with spectacle correction. YAG posterior capsulotomy was the only additional procedure. One patient had macular pigmentation consistent with either traumatic or photic maculopathy. There were no other complications attributable to the surgical procedures. We believe that certain lacerating injuries of the anterior segment are particularly amenable to cataract extraction and lens implantation at the time of primary laceration repair. This approach obviates additional operative and anesthetic risks, while affording more timely visual rehabilitation.

Obesity and weight gain are known risk factors for idiopathic intracranial hypertension (IIH; or pseudotumor cerebri). The authors examined profiles of body mass index (BMI) and patterns of weight gain associated with IIH. They also examined vision-specific health-related quality of life (HRQOL) in newly diagnosed IIH patients and explored the relative contribution of obesity and weight gain to overall HRQOL in this disorder.Matched case-control study.Female patients with newly diagnosed IIH (n = 34) and other neuro-ophthalmologic disorders (n = 41) were enrolled in a case-control study to assess patterns of self-reported weight gain. The HRQOL was examined using the 25-Item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) and the SF-36 Health Survey (Physical Components Summary and Mental Components Summary [MCS]).Higher BMIs were associated with greater risk of IIH (P = .003, logistic regression analysis adjusting for case-control matching), as were higher percentages of weight gain during the year before symptom onset (P = .004). Moderate weight gain (5% to 15%) was associated with a greater risk of IIH among both obese and nonobese patients. Obesity and weight gain influenced the relation between HRQOL and IIH only for subscale scores reflecting mental health (SF-36 MCS). The NEI-VFQ-25 and SF-36 subscale scores were lower in IIH compared with other neuro-ophthalmologic disorders and published norms.Higher levels of weight gain and BMI are associated with greater risk of IIH. Even nonobese patients (BMI30) are at greater risk for IIH in the setting of moderate weight gain. Vision-specific and overall HRQOL are affected to a greater extent in IIH than in other neuro-ophthalmologic disorders.

Purpose Severe visual acuity loss associated with pseudotumor cerebri is usually caused by chronic optic disk edema or a retinal abnormality. Method We treated a woman, with known pseudotumor cerebri treated with a lumboperitoneal shunt, who developed acute pallid optic disk swelling and visual acuity of R.E.: no light perception and L.E.: 20/70 in association with lumboperitoneal shunt failure. There were no contributory retinal lesions. Results The patient underwent optic nerve sheath fenestration and lumboperitoneal shunt revision. Visual acuity improved to 20/20 in both eyes. The papilledema resolved. Conclusion The severe sudden visual loss was attributed to axoplasmic stasis and optic nerve ischemia associated with a sudden rise in intracranial pressure.

Purpose To report a novel test that uses computerized kinetic perimetry to detect tubular visual fields in patients with functional visual loss. Design Observational case series. Methods Ten patients who demonstrated generalized visual field constriction on prior examinations underwent testing combining computerized kinetic perimetry with a reversed Galilean telescope, used for optical visual field expansion. Results Six patients with physiologic visual field constriction demonstrated expansion of their visual fields with the use of the reversed telescope. Four patients with functional visual loss responded to the reversed telescope by demonstrating tubular visual fields, with responses equal to or smaller than their demonstrated visual fields delineated without the telescope. Conclusions This test uses a computerized kinetic examination to reduce the subjective nature of tangent screen testing for tubular visual fields and to provide a computerized recording of visual fields. This method is a novel and easy-to-use technique to demonstrate functional visual loss.

PURPOSE: To report the occurrence of acquired Brown syndrome and associated magnetic resonance imaging findings in a patient with psoriasis. METHODS: A 42-year-old woman with a history of psoriasis developed pain, double vision, and limited elevation of her left eye in adduction. An orbital magnetic resonance image with gadolinium enhancement was obtained. RESULTS: Orbital magnetic resonance image disclosed abnormal enhancement of the left trochlea/tendon complex. The patient’s symptoms resolved with corticosteroid therapy. CONCLUSIONS: Acquired Brown syndrome may be associated with psoriasis. The inflammation of the trochlea/tendon complex that can cause acquired Brown syndrome can be demonstrated on magnetic resonance image.

Review of the clinical features of 48 patients with chordoma and 49 patients with low-grade chondrosarcoma of the skull base disclosed overlapping clinical profiles but distinctive features. Both tumors occurred at all ages but chondrosarcoma tended to occur in the third and fourth decades. Twenty-five (52%) of the patients with chordoma and 24 (49%) of the patients with chondrosarcoma had ocular symptoms (diplopia or visual impairment) as the initial manifestation of the disease. Of the 59 patients (both groups) with diplopia, the diplopia was initially intermittent in 25 (42%). Headache and diplopia from an insidious abducens nerve palsy was most common in both groups. Abducens nerve palsy occurred in 22 (46%) of the patients with chordoma and 23 (47%) of the patients with chondrosarcoma. Normal examination results were more common in patients with chordoma, whereas visual loss, facial numbness, and multiple cranial neuropathies were more common in patients with chondrosarcoma. The similarities in the clinical features of these tumors reflect their common origin at the central skull base and the vulnerability of the abducens nerves at that site. The differences reflect the tendency of chordomas to originate from the clivus and chondrosarcomas to originate from the temporal bone.

We analyzed the records of 132 patients hospitalized between July 1986 and February 1989 for management of traumatic hyphema. The incidence of secondary hemorrhage was compared between patients treated with or without systemic administration of aminocaproic acid in addition to an otherwise identical protocol. Results among patients who were examined within one day of injury disclosed a 4.8% secondary hemorrhage rate in aminocaproic acid-treated patients (three of 63 patients) compared with a 5.4% rate in the patients not treated with aminocaproic acid (three of 56 patients, P = .31). All six patients sustaining secondary hemorrhage recovered visual acuities of 20/40 or better, with five of six patients achieving 20/20 visual acuities. A separate group of 13 patients who were examined more than one day after injury were found to have a secondary hemorrhage rate of 38.5% (five of 13 patients). Macular injury, not secondary hemorrhage, was most often responsible among those patients suffering permanent visual loss. In this study of a predominantly white population, patients had a relatively low incidence of secondary hemorrhage and did not demonstrate detectable benefit from aminocaproic acid administration. Because of the recognized side effects and cost of treatment, further analysis to determine which patients will benefit from treatment with aminocaproic acid is indicated.

Purpose To describe the clinical presentation, orbital echography (OE) findings, and neuroimaging results of patients with chronic unexplained ocular misalignment, which includes patients with clinically occult thyroid eye disease (TED) that is identifiable through a characteristic OE appearance. Design Retrospective observational case series. Methods Seventy-eight patients with chronic ocular misalignment suspected of TED because of a history of systemic thyroid disease, proptosis, dysmotility, positive forced ductions, or eyelid retraction or lag were categorized as TED positive, negative, and indeterminate with the use of standardized OE. Demographic, clinical, OE, computed tomography, and magnetic resonance imaging information was collected. Analyses determined the prevalence of TED and differences between TED positive, negative, and indeterminate groups. Results Fifty-five percent of the findings were suspicious for and most consistent with TED (TED positive); 26% of the findings were TED negative, and 19% of the findings were TED indeterminate. Of 30 patients with newly diagnosed TED by OE, 70% had no lid retraction, and 20% had no other findings of TED. The inferior rectus followed by the superior rectus/levator complex, medial rectus, and lateral rectus muscles were the most frequently involved muscles. Neuroimaging that was performed in only 26 of 78 patients (33%) did not appear to yield additional diagnostic information. Conclusion TED is a potential cause of chronic unexplained ocular misalignment in a substantial proportion of patients. These patients frequently present in an occult fashion without other clinical findings that are typical of TED. In these patients, a diagnosis of TED by OE can reduce further costly evaluation. OE appears to have significant clinical usefulness in the diagnosis of TED in patients with unexplained ocular misalignment.
