Inverse hypopyon (hyperoleon) at the posterior segment in pathological myopia

Description

A 54-year-old woman presented a year after vitreoretinal surgery with silicone oil injection in the left eye. The left eye showed emulsified silicone oil in the anterior chamber and a posterior chamber intraocular lens. The fundus revealed a posterior staphyloma, attached retina and whitish emulsified silicone bubbles with a horizontal lower border giving rise to inverse hypopyon in the posterior pole (figure 1).

Figure 1

The fundus photo shows chorioretinal atrophy temporal to the optic disc and emulsified silicone oil bubbles with a horizontal lower level suggestive of inverse hypopyon.

Inverted hypopyon at the posterior pole1 is a rare finding which can be seen in patients with posterior staphyloma and long-term silicone oil tamponade.2 The emulsified silicone oil being lighter than fluid floats superiorly giving rise to this appearance mostly in the anterior segment (hyperoleon).
