Uncertainties and controversies surround "shaken baby syndrome" or infant "abusive head trauma". We explore Vinaccia v The Queen (2022) 70 VR 36; [2022] VSCA 107 and other selected cases from Australia, the United Kingdom and the United States. On expert opinion alone, a "triad" of clinical signs (severe retinal haemorrhages, subdural haematoma and encephalopathy) is dogmatically attributed diagnostically to severe deliberate shaking with or without head trauma. However, the evidence for this mechanism is of the lowest scientific level and of low to very low quality and therefore unreliable. Consequently, expert opinion should not determine legal outcomes in prosecuted cases. Expert witnesses should reveal the basis of their opinions and the uncertainties and controversies of the diagnosis. Further, the reliability of admissions of guilt while in custody should be considered cautiously. We suggest abandonment of the inherently inculpatory diagnostic terms "shaken baby syndrome" and "abusive head trauma" and their appropriate replacement with "infantile retinodural haemorrhage".

BACKGROUND: Submacular hemorrhage (SMH) is a sight-threatening disorder. Choroidal neovascularization secondary to age-related macular degeneration, polypoidal choroidal vasculopathy, trauma, angioid streaks, and pathological myopia are a few important causes. The conventional treatment of massive SMH is vitrectomy with manual removal of the clot with extensive retinectomy with/without tissue plasminogen activator (tPA). The usual dose of subretinal tPA is 10-25 µg. PURPOSE: To describe a new surgical approach in a case of massive SMH with retinal detachment without retinectomy. SYNOPSIS: In our case of near total hemorrhagic retinal detachment due to subretinal hemorrhage caused by trauma (road traffic accident), the patient presented with a visual acuity of counting fingers. Core vitrectomy was performed and posterior vitreous detachment was induced. The locations for retinotomy to inject and aspirate subretinal blood were selected at the maximum height of retinal elevation near the arcades. Recombinant tPA (10 µg/0.1 ml concentration; 0.3 ml injected in two locations) was injected subretinally with a 23-G soft tip cannula in the superotemporal and inferonasal quadrant causing subretinal bleb formation. Subsequently, the surgeon waited for approximately 20 min on the table for the liquefaction of the clot. The liquefied blood and tPA were drained with a silicone soft tip. Endolaser was performed at the retinotomy site and 1000cs silicone oil was injected. No signs of toxicity such as vitritis, vasculitis, or retinal necrosis were noted. HIGHLIGHTS: Our unique technique of high-dose intraoperative subretinal tPA (60 µg) is safe and helpful in rapid clot lysis and recovery of visual acuity. The patient gained a visual acuity of 20/80 from counting fingers after 1 month of surgery and 20/60 after silicone oil removal. A high dose of tPA aids in the immediate aspiration of blood from a small retinotomy. A 23-G soft tip was used instead of a 41-G subretinal cannula to inject a large quantity of subretinal tPA.

We evaluated the distribution and types of retinal hemorrhages (RHs) and other damages in eyes with abusive head trauma (AHT). This retrospective, consecutive case series of AHT and non-AHT conditions involved 54 children with AHT, 43 children with head bruises, and 49 children with blunt eye trauma, each of non-AHT supported by reliable witness accounts. RHs and other damage were evaluated using ophthalmoscopy and wide-field fundus photography. A variety of RH types and other damage were identified in the AHT group but not in the non-AHT group. RHs in AHT extended from the posterior pole to the far periphery in 77% of eyes and on/near the veins in 86% and arteries in 85%, most of which were in the far periphery. Retinoschisis, white-dot lesions, and retinal folds were seen even in the far periphery. RHs on/near the veins and arteries, retinoschisis, and retinal folds suggest a traumatic mechanism of the tractional force of the vitreous that is attached to the entire retinal surface. Identifying the distribution and arterio and venous origins of RHs is a key factor in determining the association with trauma. Thus, wide-field fundus photography is useful to record and evaluate the origin of the RHs and other retinal damage.

BACKGROUND: Intrapapillary hemorrhage with adjacent peripapillary subretinal hemorrhage is commonly observed in myopia with tilted optic disc. It presents with typical features on the fundus and follows a self-limiting course. However, due to its complex etiology, clinicians sometimes lack sufficient understanding of it which can easily lead to misdiagnosis or overtreatment. In this case report, we describe a rare case of intrapapillary hemorrhage with adjacent peripapillary subretinal hemorrhage in both eyes. CASE PRESENTATION: An 18-year-old female who has no past medical history experienced sudden black shadow blocking of her right eye in the right eye for the past 2 days after a 5-day history of COVID-19 infection. The best corrected visual acuity is 0.5 in the right eye and 0.6 in the left eye. Optical coherence tomography (OCT) showed tilted optic discs in both eyes, bulged nasal optic discs, and the presence of strong reflective material under the parafoveal retina of the optic discs. Fundus fluorescein angiography (FFA) showed subretinal fluorescence occlusion above and nasolateral to the optic disc in the right eye, with hypofluorescence below the optic disc; the subretinal below the optic disc was obscured by vitreous hemorrhage; hypofluorescence was seen in the optic disc region of the left eye.COVID-19 antigen was positive. The patient was in the early stage of the third COVID-19 infection when the disease occurred. We speculate that it may be related to it. After 5 months of conservative treatment, the patient's hemorrhage disappeared in both eyes and her best corrected visual acuity returned to normal. CONCLUSIONS: Intrapapillary hemorrhage with adjacent peripapillary subretinal hemorrhage usually occurs in myopia with tilted optic disc. In most patients, the cause of the bleeding is unknown, but it can gradually resolve under clinical observation or conservative treatment.

BACKGROUND: Immune thrombocytopenic purpura (ITP) is a rare auto-antibody mediated disease of isolated thrombocytopenia (<100,000/µL) with normal haemoglobin levels and leukocyte counts. Only a small number of ITP cases have been reported with accompanying ophthalmological findings. Herein, we report an ITP case with demonstrative retinal haemorrhages. CASE PRESENTATION: A fifty-five-year-old woman with a known history of type 2 diabetes mellitus was referred to our clinic with blurred vision. After detailed anamnesis and clinical assessment, she was diagnosed as primary ITP in haematology department, and systemic steroid (1.5mg/kg) therapy was initiated. During her follow-up, a concomitant peripheral facial paralysis (PFP) emerged. In the course of follow-up, her platelet counts increased gradually, the retinal haemorrhages regressed partially, and the PFP recovered completely. CONCLUSION: ITP is a rare haematologic disease that sometimes manifests with additional systemic involvements, and this disease should be remembered in the differential diagnosis of unusual retinal haemorrhages, which might be the only presenting feature.

INTRODUCTION: The objective of this study was to compare the outcome of submacular hemorrhage (SMH) displacement using pneumatic displacement with intravitreal expansile gas versus pars plana vitrectomy (PPV) with subretinal injection of tissue plasminogen activator (tPA), anti-vascular endothelial growth factor (VEGF) agent, and air as primary surgery. METHODS: Retrospective interventional case series of 63 patients who underwent surgical displacement of SMH secondary to neovascular age-related macular degeneration (nAMD) or polypoidal choroidal vasculopathy (PCV) from May 1, 2015, to October 31, 2022. Medical records were reviewed for diagnosis, logMAR visual acuity (VA), central subfield thickness (CST), and postoperative displacement rates and complications up to 12 months after operation. RESULTS: The diagnosis was nAMD in 24 (38.1%) and PCV in 39 (61.9%) eyes. There were 40 (63.5%) eyes in the pneumatic displacement group (38 received C3F8, 2 received SF6) and 23 (36.5%) eyes in the subretinal cocktail injection. Mean baseline VA was 1.46 and 1.62, respectively (p = 0.404). The subretinal injection group had more extensive SMH (p = 0.005), thicker CST (1,006.6 µm vs. 780.2 µm, p = 0.012), and longer interval between symptom and operation (10.65 vs. 5.53 days, p < 0.001). The mean postoperative VA at 6 months was 0.67 and 0.91 (p = 0.180) for pneumatic displacement and subretinal injection groups, respectively, though VA was significantly better in the pneumatic group at 12-month visit (0.64 vs. 1.03, p = 0.040). At least 10 mean change in VA were >10 letters gain in both groups up to 12 months. Postoperative CST reduction was greater (625.1 µm vs. 326.5 µm, p = 0.008) and complete foveal displacement (87.0% vs. 37.5%), p < 0.001, odds ratio [OR] = 11.1) and displacement to arcade or beyond (52.5% vs. 17.5%, p = 0.009, OR = 5.15) were more frequent in the subretinal injection group. Two patients with failed pneumatic displacement were successfully treated with subretinal cocktail injection as a second operation. CONCLUSION: Surgical displacement of SMH leads to clinically meaningful improvement in VA. PPV with subretinal cocktail injection is more effective than pneumatic displacement in displacing SMH with similar safety profile despite longer interval before operation, higher CST, and more extensive SMH at baseline. Retinal surgeons could consider this novel technique in cases with thick and extensive SMH or as a rescue secondary operation in selected cases.

PURPOSE: To explore the relationship between retinal hemorrhage in the green and red channels on ultra-widefield fundus images and the nonperfusion area (NPA) on ultra-widefield fundus fluorescein angiography in patients with acute branch retinal vein occlusion (BRVO). METHODS: This was a retrospective cross-sectional study with 96 patients, including 46 with ischemic BRVO and 50 with nonischemic BRVO. Correlation analysis between green channel hemorrhage (GCH), red channel hemorrhage (RCH), and NPA was performed. Panretina was divided into posterior and peripheral areas. RESULTS: Ischemic BRVO showed significantly higher GCH% and RCH% than nonischemic BRVO in the peripheral regions (both P < 0.001), whereas no significant differences were observed in the panretinal and posterior areas (all P > 0.05). Significant correlations were found between NPA% in the panretinal and peripheral areas and the corresponding GCH% and RCH% (all P < 0.01). However, no significant correlation was observed between posterior NPA% and posterior GCH% or RCH% (both P > 0.05). In addition, peripheral GCH% and RCH% were related to panretinal NPA% (r = 0.506, P < 0.001; r = 0.558, P < 0.001). CONCLUSION: Retinal hemorrhage on ultra-widefield fundus image was significantly associated with NPA, providing insights for assessing retinal perfusion status in acute BRVO patients.

BACKGROUND: Choroidal neovascularization (CNV) is a rare complication of choroideremia that occurs secondary to relative atrophy of the retinal pigment epithelium and eventual rupture of Bruch's membrane. The ideal management of CNV in choroideremia is unclear. MATERIALS AND METHODS: Case report. OBSERVATIONS: A 14-year-old male with no known ocular history presented to the eye emergency department complaining of a central scotoma in the right eye for 4 days. He had no past medical history and family history was unremarkable for known ocular disease. Visual acuity was 20/70 in the right eye and 20/30 in the left eye. Posterior segment exam revealed chorioretinal atrophy extending from the outer macula to the midperiphery in both eyes. There was CNV with associated subretinal hemorrhage in the right eye. Optical coherence tomography demonstrated the presence of CNV with subretinal fluid in the right eye and parafoveal outer retinal atrophy in both eyes. Genetic testing revealed a hemizygous exon 2 deletion on the CHM gene, pathogenic for choroideremia. The patient received a total of 3 injections 4 weeks apart followed by 1 injection 6 weeks later with resolution of the subretinal hemorrhage and reduction in CNV size with improvement in visual acuity to 20/20 at last follow-up exam. CONCLUSIONS AND IMPORTANCE: Choroidal neovascularization is a rare cause of central vision loss in patients with choroideremia. In this report, we demonstrate a good functional and anatomic response to intravitreal bevacizumab in a 14-year-old patient with undiagnosed choroideremia who presented with CNV-induced central vision loss.

The shaken baby syndrome was originally proposed in the 1970s without any formal scientific basis. Once data generated by scientific research was available, the hypothesis became controversial. There developed essentially two sides in the debate. One side claimed that the clinical triad of subdural haemorrhage, retinal haemorrhage, and encephalopathy, or its components, is evidence that an infant has been shaken. The other side stated this is not a scientifically valid proposal and that alternative causes, such as low falls and natural diseases, should be considered. The controversy continues, but the contours have shifted. During the last 15 years, research has shown that the triad is not sufficient to infer shaking or abuse and the shaking hypothesis does not meet the standards of evidence-based medicine. This raises the issue of whether it is fit for either clinical practice or for the courtroom; evidence presented to the courts must be unassailable. WHAT THIS PAPER ADDS: There is insufficient scientific evidence to assume that an infant with the triad of subdural haemorrhage (SDH), retinal haemorrhage, and encephalopathy must have been shaken. Biomechanical and animal studies have failed to support the hypothesis that shaking can cause SDH and retinal haemorrhage. Patterns of retinal haemorrhage cannot distinguish abuse. Retinal haemorrhages are commonly associated with extracerebral fluid collections (including SDH) but not with shaking. Infants can develop SDH, retinal haemorrhage, and encephalopathy from natural diseases and falls as low as 1 foot. The shaking hypothesis and the literature on which it depends do not meet the standards of evidence-based medicine.

OBJECTIVE: To compare efficacy and safety profile of subretinal aflibercept, ranibizumab, and bevacizumab in the context of pars plana vitrectomy, pneumatic displacement with subretinal air and subretinal tPA for subretinal macular haemorrhage (SMH) due to naïve neovascular age-related macular degeneration (nAMD). DESIGN: Retrospective interventional cohort study. PARTICIPANTS: 123 eyes of 123 patients treated with subretinal aflibercept (n = 41, 33%), ranibizumab (n = 41,33%), and bevacizumab (n = 41, 33%). METHODS: Review of electronic medical records for best corrected visual acuity (BCVA), central subfoveal thickness (CST), and intraocular pressure (IOP) at baseline and 24 months after treatment. MAIN OUTCOME MEASURES: BCVA, CST, and number of intravitreal anti VEGF over 24 months. RESULTS: Mean age of patients was 80.5 ± 5.5 years, 43.9% were female. Mean time from symptom onset until surgery was 1.1 days (range 0-3 days). In all cases, the SMH did not reach the arcades. CST at baseline was 627 ± 140 µ, 739 ± 54 µ, and 793 ± 93 µ (p = 0.0001) for aflibercept, ranibizumab, or bevacizumab, respectively. Baseline BCVA (logMAR) was 0.65 ± 0.13, 0.69 ± 0.96, and 0.74 ± 0.81 (p = 0.0041) for aflibercept, ranibizumab, and bevacizumab, respectively. All three groups showed statistically significant improvement in BCVA and CST (for all groups: p < 0.001). There was no statistically significant difference at the final BCVA (p = 0.789). The mean number of anti VEGF given during follow-up period was 5.2 ± 0.81, 4.4 ± 0.63, and 5.5 ± 0.95 (p = 0.0001) for aflibercept, ranibizumab, and bevacizumab, respectively. CONCLUSION: This study shows that aflibercept, ranibizumab, and bevacizumab in a subretinal manner in the context of PPV, pneumatic displacement with subretinal air and subretinal tPA for subretinal macular haemorrhage secondary to naïve nAMD work with the same efficacy and safety profile.

PURPOSE: Infantile acute subdural hematoma (IASDH) has a limited age distribution and mostly benign clinical features. Mild-type IASDH has a stereotypical clinical course which, however, has been described in only a few studies. METHODS: Four male infants (aged 6-10 months; mean age: 7.5 months) were diagnosed as mild-type IASDH associated with retinal hemorrhage (RH) after suffering from occipital impact in a fall. The present case series reviews their clinical features and neuroimaging findings, including CT and MRI findings. RESULTS: All the infants fell backwards from a standing or sitting position onto a soft surface, striking the occipital region. They began crying on impact and then soon afterwards exhibited seizure-like activity or recurrent vomiting. CT and MRI revealed a thin, unclotted subdural hematoma (SDH) without mass effect or brain parenchymal abnormality. Various degrees of bilateral RH were observed. On the day of symptom onset, all infants returned to baseline, and follow-up more than 5 years revealed normal development with no deficits. CONCLUSIONS: Mild-type IASDH with retinal hemorrhage presents with seizure-like activity or recurrent vomiting preceded by crying after an occipital impact on a soft surface. The clinical course of IASDH is followed by rapid recovery on the day of symptom onset. CT and MRI findings reveal a small, unclotted SDH without a mass effect or cerebral parenchymal abnormality.

OBJECTIVE: Nonaccidental trauma (NAT) is a major cause of traumatic death during infancy and early childhood. Several findings are known to raise the index of clinical suspicion: subdural hematoma (SDH), retinal hemorrhage (RH), fracture, and external trauma. Combinations of certain injury types, determined via statistical frequency associations, may assist clinical diagnostic tools when child abuse is suspected. The present study sought to assess the statistical validity of the clinical triad (SDH + RH + fracture) in the diagnosis of child abuse and by extension pediatric NAT. METHODS: A retrospective review of The University of Arizona Trauma Database was performed. All patients were evaluated for the presence or absence of the components of the clinical triad according to specific International Classification of Diseases (ICD)-10 codes. Injury type combinations included some variation of SDH, RH, all fractures, noncranial fracture, and cranial fracture. Each injury type was then correlated with the ICD-10 codes for child abuse or injury comment keywords. Statistical analysis via contingency tables was then conducted for test characteristics such as sensitivity, specificity, positive predictive value, and negative predictive value. RESULTS: There were 3149 patients younger than 18 years of age included in the quantitative analysis, all of whom had at least one component of the clinical triad. From these, 372 patients (11.8%) had a diagnosis of child abuse. When compared to a single diagnosis of either SDH, RH, all fractures, noncranial fracture, or cranial fracture, the clinical triad had a significantly greater correlation with the diagnosis of child abuse (100% of cases) (p < 0.0001). The dyad of SDH + RH also had a significantly greater correlation with a child abuse diagnosis compared to single diagnoses (88.9%) (p < 0.0001). The clinical triad of SDH + RH + fracture had a sensitivity of 88.8% (95% CI 87.6%-89.9%), specificity of 100% (95% CI 83.9%-100%), and positive predictive value of 100% (95% CI 99.9%-100%). The dyad of SDH + RH had a sensitivity of 89.1% (95% CI 87.9%-90.1%), specificity of 88.9% (95% CI 74.7%-95.6%), and positive predictive value of 99.9% (95% CI 99.6%-100%). All patients with the clinical triad were younger than 3 years of age. CONCLUSIONS: When SDH, RH, and fracture were present together, child abuse and by extension pediatric NAT were highly likely to have occurred.

Westwood, Jessica, India Mayhook-Walker, Ciaran Simpkins, Andrew Darby-Smith, Dan Morris, and Eduardo Normando. Retinal vascular changes in response to hypoxia: a high-altitude expedition study. High Alt Med Biol. 25:49-59, 2024. Background: Increased tortuosity and engorgement of retinal vasculature are recognized physiological responses to hypoxia. This can lead to high-altitude retinopathy (HAR), but incidence reports are highly variable, and our understanding of the etiological mechanisms remains incomplete. This study quantitatively evaluated retinal vascular changes during an expedition to 4,167 m. Methods: Ten healthy participants summited Mount Toubkal, Morocco. Fundus images were taken predeparture, daily throughout the expedition, and 1 month postreturn. Diameter and tortuosity of four vessels were assessed, in addition to vessel density and features of HAR. Results: Significant (p ≤ 0.05) increases in tortuosity and diameter were observed in several vessels on high-altitude exposure days. There was a strong correlation between altitude and supratemporal retinal artery diameter on days 2, 3, and 6 of the expedition (r = 0.7707, 0.7951, 0.7401, respectively; p < 0.05). There was a significant increase in median vessel density from 6.7% at baseline to 10.0% on summit day. Notably there were no incidences of HAR. Conclusion: Physiological but not pathological changes were seen in this cohort, which gives insight into the state of the cerebral vasculature throughout this expedition. These results are likely attributable to relatively low altitude exposure, a conservative ascent profile, and the cohort's demographic. Future study must include daily retinal images at higher altitudes and take steps to mitigate environmental confounders. This study is relevant to altitude tourists, patients with diabetic retinopathy or retinal vein occlusion, and critically ill patients.

Clinically, hemorrhages at the vitreoretinal interface have been termed as 'pre-retinal' in location. However, there is a careful distinction to be made between sub-hyaloid and sub-internal limiting membrane (ILM) planes of blood collection. In the past half-century, a body of literature has accrued on sub-internal limiting membrane hemorrhage. We characterize the etiopathological, clinical, anatomical, and imaging characteristics of this entity (often misconstrued as sub-hyaloid hemorrhage). Management decisions are briefly described, and a unifying term of sub-internal limiting membrane macular hemorrhage is proposed to aid in further research.

PURPOSE: To report the clinical manifestations and outcomes of patients who experienced retinal damage due to accidental laser exposure during a festival in Kolhapur, Maharashtra. METHODS: Consecutive patients who presented with sudden loss of vision following exposure to laser lights during a religious Indian festival (Ganapati festival) on the same day (9 September 2022) at the same location (idol visarjan procession) were identified from the medical records of various eye hospitals in Kolhapur district of Maharashtra. Eyes with persistent subhyaloid hemorrhage (SHH) were taken up for neodymium-doped yttrium aluminum garnet (Nd: YAG) posterior hyaloidotomy. Patients were examined at weekly intervals up to 1 month. RESULTS: Thirty-four eyes of 34 men were identified with age ranging from 18 to 27 years. The mean duration of exposure to the laser projections was 4.9 ± 1.7 h, and the mean distance from the laser source was 7.3 ± 2.7 feet. All presented with SHH involving the macula. SHH had a median size of 3 disc diameters or larger in 30 eyes (88%), and 29 (97%) of these required hyaloidotomy while one patient underwent pars plana vitrectomy. The mean visual acuity improved from 1.45 ± 0.5 log of minimum angle of resolution (logMAR; 20/560 Snellen) to 0.11 ± 0.19 logMAR (20/25 Snellen) (P < 0.001). One eye showed full-thickness macular hole with visual acuity of 20/200. CONCLUSION: We report a large number of patients experiencing laser-induced SHH, resembling an outbreak, due to exposure to a malfunctioning high-powered recreational laser during a religious festival.

INTRODUCTION: Submacular hemorrhage (SMH) is a vision-threatening complication of neovascular age-related macular degeneration (AMD). The exact treatment scheme is not established yet. The aim of the current study was to describe surgical results and fundus autofluorescence (FAF) patterns after pars plana vitrectomy (ppV) + subretinal tissue plasminogen activator (tPA) + anti-vascular endothelial growth factor (VEGF) and intravitreal tPA + anti-VEGF + sulfur hexafluoride (SF6) tamponade and to compare them to intravitreal tPA + anti-VEGF + SF6 in the treatment of SMH in the course of AMD. MATERIALS AND METHODS: We performed FAF imaging in patients with a previous SMH in the course of AMD with a duration of <60 days treated with vitrectomy with subretinal anti-VEGF and tPA and intravitreal anti-VEGF, tPA, and SF6 administration (group 1) or intravitreal tPA + anti-VEGF + SF6 (group 2). In all eyes, a throughout ophthalmic examination, fluorescein angiography, and spectral domain optical coherence tomography (SD-OCT) were done for diagnosis. SD-OCT was performed monthly during treatment. RESULTS: Three FAF patterns were observed in both groups. Pattern one (normal autofluorescence) was observed in 5/18 in group one and 5/21 group two. Pattern two was observed in 6/18 in group one and 7/21 in group two. Pattern three was noted in 7/18 in group one and 5/21 in group two. Improvement in visual acuity was statistically significant for both groups: 0.01 Snellen (2.0 logMAR) to 0.11 Snellen (0.96 logMAR) in group one (p = 0.019) and 0.11 Snellen (0.96 logMAR) to 0.33 Snellen (0.48 logMAR) in group two (p = 0.0007). Central retinal thickness also decreased with statistical significance for both groups (p < 0.05). CONCLUSION: FAF patterns did not depend on the treatment used, but solely on the duration of SMH before treatment. SMH if not treated prompt enough might cause long-standing photoreceptor and retinal pigment epithelium defect, which is represented by hypo- and hyperautofluorescence. Performing a subretinal injection of tPA and anti-VEGF does not cause any defects associated with the injection site. That might be associated with previous local internal limiting membrane peeling, which reduces the injection pressure. Not only prompt treatment of SMH but also further continuation of anti-VEGF treatment is mandatory to maintain vision.
