I don't know if you fly much these days, but anyone who does surely has noticed the airlines new
strategy: they charge a fee—often outrageous and absurd, for just about everything they can. Rather than just
being a blatant rip off, these fees are actually the stuff of genius. Let me explain.

Simultaneous Injuries to Both Eyes in Traffic Accidents | ||||
In traffic accidents, eye injuries occur as isolated or with polytrauma. They may involve just one eye, but simultaneous injuries
to both eyes do happen occasionally. The aim of this paper was to reveal the risk factors, in an effort to reduce the number of
such accidents and to prevent bilateral ocular damage. All patients hospitalized at the Clinic of Eye Diseases, Clinical Center
of Serbia, Belgrade, due to traffic accidents with bilateral eye injuries in a period of 9 years from the beginning of 2000 to
the end of 2008 were analyzed.
In this 9-year period, a total of 36 patients were hospitalized and treated for bilateral ocular injury (72 eyes). There were 23 males among them, the male-female ratio being 1.8:1. Mean age was 33.9 years. The occupations of injured persons were the following: the most common were workers (15), followed by clerks (7), while less common were pupils, students, pensioners and housewives (3 of each of them), and farmers (2). Front-seat passengers were the most common among the injured (20, 55.6%), then drivers (15, 41.7%), with only one passenger from the back seat on the right side (2.7%). As many as 33 (91.7%) of them failed to fasten their seat belts, while 18 (50.0%) were drunk. Penetrating bulbar injuries or eyeball ruptures were predominant (66.7%), while blunt injuries were found in only two (2.8%) eyes in one single person; but in 22 cases (30.5%) there was adnexal damage, too. Visual acuity at discharge and subsequent controls was as follows: amaurosis in 21 (29.2%), less than 0.3 in nine (5.6%), 0.4 and better in 42 (58.1%), and normal visual acuity of 1.0 in 28 patients (38.3%). The major risk factors for getting bilateral eye injuries in traffic accidents proved to be: sitting in the front car seats, not fastening the seat belt and alcohol intoxication. Prevention of these risk factors would result in a decrease in such a large number of bilateral eye injuries. |

Cluster Headache Associated With a Sixth Nerve Palsy: A Case Report | ||||
Cluster headache is a rare primary headache disorder characterized by recurrent, stereotyped
short-lasting attacks of severe, unilateral head pain accompanied by autonomic symptoms.
Ophthalmic features such as conjunctival injection, lacrimation, ptosis and miosis occur in the vast majority of patients with cluster headache, whereas co-existent ocular movement disorders are rare. To the best of our knowledge, only two documented cases of cluster headache with external ocular movement disorders have been reported. Herein an additional case with this unusual finding and discuss the putative pathophysiology of cluster headache associated with ophthalmoparesis. |

Cat-Scratch Disease: Ocular Manifestations and Visual Outcome | ||||
Clinical records of patients diagnosed with cat-scratch disease (CSD) in the Uveitis Department
of São Geraldo Hospital and the Ophthalmology Department were reviewed from 2001 to 2008 to describe the
intraocular manifestations of CSD found at two uveitis reference centers in Brazil.
In the 8-year period, 24 patients with the diagnosis of CSD were identified. Twelve patients were male and 12 female. The mean age was 27.04 years (range 7–56). Sixteen patients (66.6%) presented with a history of a cat scratch and all patients reported cat exposure. Visual acuity ranged from counting fingers to 1.0 in the affected eye. Thirteen patients presented with bilateral disease. Sixteen (66.6%) patients complained of systemic symptoms, including fever, lymphadenopathy, liver and spleen enlargement and rash. All patients presented with serum antibodies (IgG) to Bartonella henselae. A total of 37 eyes were affected. The most common findings were small areas of retinal infiltrates, which occurred in 11 eyes (29.7%) and angiomatous lesions, which occurred in nine eyes (24.3%). Neuroretinitis occurred in only six eyes (16.2%). The most common findings of CSD in our study were retinal infiltrates and angiomatous lesions. CSD patients may present with significant visual loss. Patients may benefit from systemic treatment with antibiotics. |
