Terson first reported associations between intracranial hem-orrhage and vitreous hemorrhage in 1900.1 Since then,Terson’s syndrome has been defined as vitreous or retinalhemorrhage in the presence of intracranial hemorrhage,occurring in 12.5% to 40% of individuals.2– 6 It is be-lieved that ruptured intracranial aneurysm or head traumarapidly increases the intracranial pressure.3,5 This pres-sure is transmitted through the optic nerve sheath andveins to the optic nerve head and retina, causing ruptureof thin capillary walls.3,5

Reported complications of Terson’s syndrome include vi-sual loss,7 macular holes,8 epiretinal membrane formation,9,10

retinal folds,10,11 proliferative vitreoretinopathy,12,13 and reti-nal detachment.13 It has been suggested that these complica-tions are the result of proliferation of glial and retinal pigmentepithelial elements capable of causing retinal distortion andfibrotic adhesions.8

Reports of the pathology of eyes with Terson’s syndromeare limited. Some reports describe epiretinal membranes.14

Others show blood dissecting between the internal limitingmembrane (ILM) and underlying Müller cell end plates.15

One case report demonstrated preretinal, sub-ILM, intrareti-nal, and optic nerve sheath hemorrhage.16 The present re-port describes 1 representative case, analyzes 30 selected

Materials and Methods

Indices of histopathology and photographic collections of casesdiagnosed as “Terson’s syndrome” in the Wm R. Green Labora-tory of Ocular Pathology were searched, retrieved, studied, andselected as emblematic of common features.

Thirty-nine cases were based on autopsies from The JohnsHopkins Hospital, Hopkins Bayview Hospital, or Greater Bal-timore Medical Center. Fifty-eight cases were acquired fromMaryland, Florida, Washington, Delaware, West Virginia, orinternational Eye Banks. Histologic sections were stained withhematoxylin and eosin or Verhoeff-Van Gieson. Twelve caseswere based on histopathologic sections prepared by RichardLindenberg, MD, a neuropathologist at the Maryland MedicalExaminers Office, who donated his collection of ocular tissuesto the Wm R. Green Laboratory. These sections were preparedby unroofing optic canals to study long sections of wholenerves, stained with iron stain or Verhoeff-Van Gieson.

The location and severity of tissue deposition of blood was thedefining characteristic in this study. The eyes of all individualswere classified as either trauma or primary intracranial hemorrhageand their ages tabulated (Fig 1).

age distribution of the 109 individuals studied, where Terson’ssyndrome was caused by trauma, intracranial hemorrhage, orunknown.

Thirty eyes from 16 individuals were randomly selected from109 cases to be specially examined microscopically. Table 1describes the age, gender, cause of death, estimated number ofdays between onset of Terson’s syndrome and death, and timebetween death and autopsy. Ten of the 16 individuals were female.Causes of death include trauma (fall, motor vehicle accident,gunshot) or subarachnoid hemorrhage from ruptured intracranialaneurysm or hypertension. All cases involved intracranial hemor-rhage. One case (Table 1, number 13) was notable for Marfan’ssyndrome. Ten individuals died within 2 days of onset of Terson’ssyndrome, 3 individuals died after 3 to 5 days of onset, and in 3,the duration was unknown.

The following representative case (Table 1, number 14) isdescribed. A 40-year-old woman with a history of hypertensionpresented with sudden onset headache on March 5, 1997. Com-puted tomography at that time was unremarkable. Over theensuing 2 months, she experienced intermittent headaches. OnMay 3, 1997, she noticed dizziness with her headaches. On May10, 1997, she was found unresponsive at home. Repeat com-puted tomography revealed an intraparenchymal hematoma ofthe left frontal lobe and hemorrhage into the left lateral ventri-cle; no significant midline shift or herniation was noted. Afterprogressive worsening of her Glasgow Coma Score, an intra-ventricular catheter was placed. Subarachnoid hemorrhage withassociated cerebral edema caused mass effect and uncal herni-ation. The individual rapidly developed progressive encepha-lopathy and died on May 11, 1997. In hospital, it was observedthat the right pupil did not react to direct stimulation. Ocularfundoscopy was not reported.

Postmortem examination on May 12, 1997, revealed a 7-mmberry aneurysm of the left anterior communicating artery withassociated hematoma, subarachnoid hemorrhage, and extensivecerebral edema. The left frontal cortex contained a 2.5-cm hema-toma. There was diffuse subarachnoid hemorrhage. The mid-

Grossly, the right eye showed subconjunctival hemorrhage(4 � 2 mm) at the superotemporal limbus and 3 well-demarcated,dome-shaped peripapillary retinal hemorrhages (1.0–1.5 mm indiameter). No vitreous hemorrhage was noted. Microscopic exam-ination revealed 2 areas of hemorrhage in the outer plexiform layer(OPL), one in the temporal aspect of the macula, the other 1.5 mmanterior to the optic nerve. Figure 2 demonstrates outer plexiformmacular hemorrhage. The optic nerve was remarkable for crushartifact. Additional hemorrhages were seen in the subarachnoidspace, the subdural space, and within the dural sheath of the opticnerve.

The left eye grossly showed subconjunctival hemorrhage(4.0 � 2.5 mm) at the temporal limbus, a dome-shaped sub-ILMhemorrhage with raised edges inferior and temporal to the opticdisc (Fig 3A), and a retinal hemorrhage (1 mm in diameter)inferior and nasal to the optic disc. Microscopically, a large hem-orrhage (9 mm in diameter) was present beneath ILM at themacula. Hemorrhage was also detected in the inner nuclear layer,OPL, and beneath the retina.

The range of pathology observed among the 30 specificallystudied eyes is summarized in Table 2 (available online athttp://aajournal.org). Vitreous hemorrhage was present in 11eyes (Fig 4A) and diffuse subhyaloid hemorrhage was presentin 10 eyes (Fig 4B). Intraretinal hemorrhage was present in alleyes: 23 eyes had well-demarcated, dome-shaped hemorrhagebeneath the ILM (Fig 4B–C), 16 eyes had blood in the ganglioncell layer (Fig 5), 19 eyes had hemorrhage in bipolar cell layer (Fig5), 20 eyes had hemorrhage in the OPL (Fig 5), 9 eyes had hemor-rhage in outer nuclear layer (Fig 6), and 4 eyes had hemorrhage of therods and cones (Figs 6 and 7). Subretinal hemorrhage was seen in 14eyes (Figs 5B and 7). Figure 7 demonstrates infiltration, distension,and rupture of the macula from an individual who died within 2 daysof intracranial hemorrhage. Notably, no eyes had hemorrhage in theinner plexiform layer (IPL).

Hemorrhage was present in the dural sheaths of 9 eyes, in thesubdural spaces of 19 eyes, in the subarachnoid spaces of 20eyes, and within the pia mater of 2 eyes (Fig 9). Figure 10A–Cfrom the Lindenberg collection shows optic nerve hemorrhagesfrom 2 individuals who died after trauma. Figure 10A demon-strates focal dural and subdural hemorrhage in midorbital opticnerve, with no evidence of extensions from intracranial bloodalong optic nerve canal. Distended anterior retinal veins can beseen in this eye (Fig 10B). Figure 10C demonstrates severesubdural blood from the optic chiasm, along the optic canal, tothe optic nerve scleral junction.

Discussion

Terson’s syndrome has been reported to cause epiretinalmembranes, retinal folds, proliferative vitreoretinopathy,retinal detachment, and macular holes.8 –13 Our his-topathologic analysis was undertaken to increase under-standing of mechanisms which threaten vision. As shownin Figure 1, our study found a wide range of individualages. The elderly mainly died of vasculogenic intracra-nial hemorrhages; younger individuals largely died oftrauma-related causes.

Vitreous hemorrhage (Fig 4A) in the visual axis ob-viously reduces visual acuity. Figure 4B demonstrates athin layer of hemorrhage overlying retina. Yokoi et al9

proposed that vitreous hemorrhage breaks down the ILM,causing glial cell migration and proliferation into thevitreous cavity and epiretinal membrane formation.9 Thispossibility provides an argument for early, operative re-moval of blood.

Previous authors have attempted to distinguish be-tween subhyaloid and sub-ILM hemorrhages.15,17 Wefound that subhyaloid hemorrhages are diffuse, irregu-larly edged, and vary in density (Fig 4C), whereas sub-ILM hematomas are well-demarcated and dome shaped(Fig 3A, B).

Both subhyaloid and sub-ILM hemorrhages can bepresent in the same area (Fig 4B). This corroborates apreviously reported “double ring” sign caused by con-current subhyaloid and sub-ILM hemorrhage.18 Fig-ures 3C–D show points at which ILM detaches fromunderlying retina. Hematoma beneath the ILM can causeelevation of the membrane, explaining the “macularring”18 reported by Sadeh et al19; as the sub-ILMhemorrhage contracts and serum is absorbed, the remain-ing ILM wrinkles and is seen as a folded, reflectivesurface.

Blood may elevate retina, causing retinal folds, pro-liferative vitreoretinopathy, and retinal detachment (Figs5 and 6). In some individuals, decreased visual acuitypersists after surgery.4,20,21 Blood at various layers of theretina (Fig 5), particularly at the macula (Fig 6), mayexplain the long-term loss of visual acuity.

Although hemorrhage was seen throughout the retina andsubretinal space, it was not found in the IPL of any eye (Figs2A, 3B, C, 4B, 5, 6 and 7). Even when there was massivehemorrhage throughout the retina, the IPL was spared. Thisimplies that the IPL is a layer of decreased vascularity and

vulnerability.

1428

Disruption of retina by hemorrhage caused macularhole in an individual who died within 2 days of onset ofTerson’s syndrome (Fig 7). There was no apparent vit-reoretinal traction, the prevailing mechanism proposedby Gass.22 In this case, there was no clinical informationof prior macular disease. The obvious traumatic disrup-tion of the retina is consistent with blood dissecting fromruptured vessels and entering the retinal layers and sub-retinal space to weaken and disrupt the macula, resultingin a macular hole. Development of a hemorrhage-inducedmacular hole within 2 days argues for early evaluation ofthe retina in clinically stable individuals.

Hemorrhage of the optic nerve sheath is a frequentcomplication of Terson’s syndrome23; in this study, itoccurred within the dural sheath, subdural space, sub-arachnoid space, or pia mater (Fig 9). Figure 10A dem-onstrates multifocal optic nerve hemorrhages. In 1943,Ballantyne24 proposed and presented evidence that in-traocular and subdural optic nerve hemorrhages of Ter-son’s syndrome were locally multifocal and not exten-sions of intracranial blood. According to this explanation,multiple foci of hemorrhage can cause continuous bloodalong optic nerve canal from chiasm to sclera (Fig 10B).Although it is possible that there are 2 mechanisms forTerson’s syndrome, we believe multifocal bleeding is themost common.

This study is limited in that eyes used for histopatho-logic analysis were necessarily acquired from deceasedindividuals, possibly describing a range of disease that ismore severe than what is usually seen clinically. Futurestudies could determine whether the range of histopatho-logic findings correlates with severity of disease by in-corporating orbital ultrasound, ocular coherence tomo-graphy, and magnetic resonance imaging. From thisstudy, we see a need for clinicians to be more aggressivein early evaluation of individuals with head traumaand subarachnoid hemorrhage from ruptured intracranialvessels.

Current recommendations in literature suggest 3 to 6months of observation after the acute event, followed byvitrectomy if there is no improvement in visual acu-ity.6,25–28 This report demonstrates a range of pathologythat occurs within 1 week of onset of Terson’s syndrome,including vision-threatening findings of vitreous hemor-rhage, retinal hemorrhage, foveal damage, and macularhole. Our study suggests that earlier definition of theextent and location of bleeding, before 3 months, canoptimize clinical management. Although it is not possibleto obtain histopathology without damaging eyes of livingindividuals, ultrasound, magnetic resonance imaging, andocular coherence tomography can bridge the gap betweenclinical and pathologic findings. These diagnostic stud-ies, together with knowledge of the range of disease thatoccurs in Terson’s syndrome demonstrated by our study,may guide clinicians in determining whether earlier sur-gery may improve clinical outcomes of visual acuity and

rehabilitation.
