Perfluorocarbon liquid (PFCL) has been widely used in vitreoretinal surgeries, especially in retinal detachment treatment. A prominent complication of intraoperative PFCL application is inadvertent subretinal PFCL retention. Subfoveal PFCL, even in small amounts, receives much attention due to its potential side effect on the macular structure and function. Whether to observe with follow-up or to deal with surgery is often an intractable problem in the management of subfoveal PFCL. Safety and necessity are the 2 key issues in considering surgical treatment, that is, can we avoid surgically induced macular injury and will surgery be beneficial for the recovery of vision? Herein, the authors review sub-foveal PFCL retention with its risk factors, morphological manifestations, pathological studies, clinical natural consequences, and different surgical methods with their outcomes...

REVIEW
Argyrios Chronopoulos, Jong Min Ong, Gabriele Thumann, James S Schutz
Occult globe rupture is a traumatic dehiscence of the sclera at or posterior to the rectus muscle insertions without a visible eye wall defect on slit lamp examination. Occult scleral ruptures are important because they can be difficult to diagnose, but normally require preoperative protection against external pressure to reduce risk of herniation of ocular contents through the rupture and then urgent surgical repair to restore eye wall structural integrity and achieve optimum prognosis. A deeper than normal anterior chamber with posteriorly retracted plateau iris seen immediately after acute ocular trauma is virtually pathognomonic of posterior globe dehiscence...

Background: To report two cases of rhegmatogenous retinal detachment (RRD) associated with asteroid hyalosis (AH). Case Presentation: Two patients presented with RRD originating from a flap tear. Case 1 involved a 62-year-old male who was found to have bullous RRD in his left eye originating from a flap tear. During vitreous surgery, a thick vitreous cortex was found to have strongly adhered to the entire retinal surface, from the center to the periphery. A bimanual method was then used in conjunction with the vitrectomy to create an artificial posterior vitreous detachment...

Endoscopy-assisted ocular surgery is a relatively old technique that is increasingly being recognized for its application in cases of vitreoretinal disease. This technique is especially useful when both the vitreous and retina are difficult to access because of media opacity, a small pupil, or a microcornea. In this context, the anterior vitreous is often difficult to dissect because of its complex pathological changes. This article reviews the common anatomical features and pathologies that are observed in the anterior vitreous, as well as the applications and indications of endoscopy-assisted vitrectomy in the anterior vitreous...

We discuss the case of a 49-year-old soldier with a macula-on rhegmatogenous retinal detachment in Sierra Leone. The case highlights the challenge of accessing visually preserving ophthalmic specialist care in sub-Saharan Africa (SSA) for vitreoretinal (VR) disease. It highlights a shortage of VR surgeons in SSA, limited examination facilities, the larger issue of accessing specialist care urgently and the costs associated with accessing surgery out-of-country. It also identifies a shortage in epidemiological data on the issue which limits the assessment of the scale of the problem...
