| Abstract|| |
Pathologies of the vitreomacular interface are implicated in a variety of sight-threatening clinical entities. The authors present a photo essay of a case of Terson syndrome with a striking premacular dehemoglobinized hemorrhage with ovoid morphology. This unique “vitelliform” finding highlights the distinct structure of the premacular vitreous space and its important implications in both health and disease.
Keywords: Dehemoglobinized hemorrhage, premacular bursa, Terson syndrome, vitreomacular interface, vitreoretinopathy

A 53-year-old man noted vision loss in the left eye (OS) 2 weeks following a subarachnoid hemorrhage. Best-corrected visual acuity OS was counting fingers without pinhole improvement, and intraocular pressure was 14 mmHg by contact tonometry. Dilated fundus examination revealed a large, well-circumscribed, egg-shaped subhyaloid dehemoglobinized hemorrhage overlying the macula, consistent with Terson syndrome [Figure 1]a. No other vitreoretinal pathologies were noted on examination, and the evaluation of the fellow eye was unremarkable. Optical coherence tomography (OCT) confirmed the location of this “vitelliform” hemorrhage within the preretinal space [Figure 1]b. The hemorrhage resolved 5 weeks later, and the vision improved to 20/30.

These images underscore the ability of the remarkable cavity confined between the posterior vitreous cortex and the macula – described by Worst as the bursa premacularis – to allow for blood to adapt striking configurations that can impair vision. The clinical significance of this bursa and its potential role in the pathogenesis and treatment of various clinical entities have gained increased understanding. For example, swept-source OCT evidence indicates that this cavity fuses with Cloquet's canal in eyes before the onset of vitreous degeneration, suggesting the presence of a direct connection between the premacular, preoptic, and retrolental spaces and a route for aqueous humor to access the premacular bursa. Other analyses have demonstrated the importance of this bursal space in the progression of proliferative diabetic retinopathy. In addition, an understanding of mechanical forces exerted within this region may lend insight into the pathogenesis of vitreomaculopathies and other clinical phenomena, including macular hole, posterior vitreous detachment, and even abusive head trauma. Further, given the increased heterogeneity of vitreous structure with age, diabetes, and myopia, this space has even been suggested as a potential site of targeted intraocular drug delivery, as it is conceivable that the pharmacokinetics of medications may vary substantially depending on location of injection within the vitreous body.
The uniquely shaped hemorrhage observed in this case – which may, at first glance, be subtly reminiscent of other disease entities, such as vitelliform macular dystrophy – highlights the vitreomacular interface's distinct anatomy, which is of profound importance in both health and disease.
