“…Initial theories suggested that blood in the subarachnoid space could track directly into the sclera and vitreous space through the lamina cribrosa [1][2][3] . However, anatomic studies have failed to demonstrate a connection joining the subarachnoid space of the optic nerve sheath to the vitreous space 1,4 . Moreover, vitreous hemorrhage has been documented to occur with diseases other than SAH 5 .…”

A 51-year-old male was admitted following subarachnoid hemorrhage (SAH) (Figure 1). His Glasgow coma score was 15. Other than headache and a defect in his right visual field, his neurological exam was normal. Cerebral angiography demonstrated a 3 mm anterior communicating artery aneurysm which was successfully excluded with endovascular coiling. Due to persistent visual complaints, an ophthalmology consult was obtained, which revealed a scotoma of the right eye. Fundoscopy demonstrated a large subhyaloid hemorrhage of the right eye (Figure 2), and a small retinal hemorrhage with papilledema of the left eye. Intraocular pressure was slightly higher than normal, 31 mmHg, in both eyes. The diagnosis of Terson’s syndrome (TS) was made, and the decision was made to follow him conservatively for at least six months.

“…Therefore, the space assumes the character of a trabecular meshwork of closely knit fibers in the canal. Walsh anil Hedges [48] also concluded from their his tological examination of the canal in man that 'any free space which exists in the optic canal must be very small indeed'. The adhe sions between the dura and the optic nerve are not uniform on all sides.…”

The Sheath of the Optic Nerve

The sheath of the optic nerve was studied in rhesus monkeys, humans, and rabbits. The sheath (i.e., dura mater and arachnoid mater) was normally found to be loose near the eyeball, with a much bigger space between the optic nerve and the sheath than anywhere else in its course, consequently presenting bulbous appearance just behind the eyeball. The space was narrowest in the region of the optic canal, with thick fibrous bands stretching from the dura mater to the pia mater of the optic nerve – so that the space assumed the character of a trabecular meshwork of closely knit fibers in the canal, with the subarachnoid and subdural spaces reduced to almost a capillary size in this region. Communication between the subarachnoid spaces of the cranial cavity and of the sheath was almost always seen; however, the extent of communication in the optic canal showed wide variation from one specimen to another. The significance of our findings in the interpretation of some clinical and pathological findings and processes is discussed.

“…The sudden increase intracranial pressure in cases of SAH is transmitted through the subarachnoid communications and the optic canal to the intravaginal spaces around the optic nerve, where the subarachnoid space ends in a cul de sac (Manschot, 1954;Riddoch and Goulden, 1925;Walsh and Hedges, 1951). These intravaginal spaces expand as a result of the sudden increase in pressure and the accumulation of blood and CSF.…”

“…These intravaginal spaces expand as a result of the sudden increase in pressure and the accumulation of blood and CSF. The central retinal vein will be compressed and stretched (Manschot, 1954;Riddoch and Goulden, 1925;Walsh and Hedges, 1951) and as a result there will be abrupt venous stasis. Pressure increases and a back pressure from the central vein to the retinal venous branches occurs.…”

We report on two patients with bilateral vitreous haemorrhage after a subarachnoid haemorrhage (Terson syndrome). We performed vitrectomy in four eyes with complete recovery of vision in three eyes; one eye had visual acuity of 1/6 due to preretinal fibrosis. The patient who had 20/20 vision in both eyes had a retinal detachment in one eye two months after the vitrectomy; this was operated upon and vision did not deteriorate.
