Vitreous hemorrhage in children and adolescents in India

Anterior chamber fluorescein leakage in a child with intraocular pressure elevation and vitreous hemorrhage

Purpose

To report a case of a child with neovascular and ghost cell glaucoma in the setting of previously treated vitreous hemorrhage with unique fluorescein leakage from abnormal iris vessels ultimately preventing successful fluorescein angiography.

Observations

A 3-year-9-month-old female with a medical history of very high-risk B-cell acute lymphoblastic leukemia presented with eye pain and was noted to have a complete vitreous hemorrhage and intraocular pressure elevation in the right eye which was refractory to maximum medical therapy and vitrectomy. Following vitreous hemorrhage resolution, an examination under anesthesia with fluorescein angiography was found to have diffuse leakage of fluorescein into the anterior chamber, presumably due to the active iris neovascularization. This anterior chamber fluorescein signal prevented visualization of the retinal vasculature. The patient was diagnosed with mixed mechanism glaucoma (neovascular and ghost cell) due to a resolved vitreous hemorrhage in the setting of a presumed prior ischemic event.

Conclusions and Importance

We report a case of an unsuccessful fluorescein angiogram in the setting of anterior chamber fluorescein leakage due to active iris neovascularization, and review considerations for the differential diagnosis and useful diagnostic tests in this clinical scenario.

Unusual eye injury related to abusive head trauma

Ophthalmological examination is an essential component in clinically diagnosing abusive head trauma (AHT). Typical of AHT injuries is retinal bleeding, with other parts of the eye sometimes also being affected. Visual impairment and blindness are long-term complications in this context. We present a case with unusual eye injuries after a diagnostically confirmed AHT.

The ophthalmological findings on admission day showed a massive subhyaloid hemorrhage at the posterior pole and extensive flame-shaped intraretinal hemorrhages accented on the right side., A centrally localized vitreous hemorrhage appeared on both sides 3 weeks later, obscuring the optic disc and macula most probably due to a breakthrough of a sub-internal limiting membrane (ILM) hemorrhage into the vitreous cavity. Follow-up 4 weeks later revealed a dense and organized vitreous hemorrhage occupying the optic disc and macula so that a pars plana vitrectomy was performed on both eyes.

The bilateral bleeding in different retinal layers, the vitreous hemorrhage and the proliferative vitreoretinal reaction (PVR) indicated massive damage caused by a significant acceleration-deceleration trauma. A two-phase vitreous hemorrhage in a child with AHT does not yet appear to have been described in the literature.

Analysis of the etiologies, treatments and prognoses in children and adolescent vitreous hemorrhage

AIM

To determine the etiologies, treatment modalities and visual outcomes of vitreous hemorrhage (VH; range from birth to 18y).

METHODS

A total of 262 eyes from 210 patients between January 2010 and September 2016 were included. All children underwent an appropriate ocular and systemic examination. Data collected included demographics, clinical manifestations, details of the ocular and systemic examination, management details, final fundus anatomy and visual acuity (VA).

RESULTS

The most common etiologies were non-traumatic VH (64.89%), most of which were due to retinopathy of prematurity (ROP; 37.10%); while traffic accidents, including 16 (21.00%) eyes, was the most common ocular traumas. Surgery, performed in 143 (54.58%) eyes, was the most common management modality. The initial mean baseline visual acuity was 2.77±0.21 logarithm of the minimal angle of resolution (logMAR) in children and adolescent with traumatic VH, which was significantly improved to 2.15±1.31 logMAR (P<0.05).

CONCLUSION

VH in children and adolescent has a complicated and diverse etiology. ROP is the primary cause of non-traumatic VH, which is the most common etiology. Appropriate treatment of traumatic VH is associated with obvious improvement in visual acuity. The initial VA is one of most important predictors of outcome.

Efficacy and safety of Chinese medicines for vitreous hemorrhage: A protocol for systematic review and meta-analysis

BACKGROUND

Vitreous hemorrhage (VH) is a common ophthalmic disease with a high rate of blindness, which will seriously affect the quality of life of patients and bring great burden to patients' families and society. The treatment for VH contains medical therapy, lasers, and surgery. At present, there is no recognized western medicine with definite curative effect and little side effect for the treatment of VH. In most cases, PRP is not available to treat VH; intravitreal injection or surgical treatment is adopted as the primary therapy. However, in the long-term treatment, the effect of the above-mentioned treatment is not satisfactory, so many patients choose oral Chinese medicines, which has been widely used in China to treat VH. Numerous clinical trials have demonstrated that Chinese medicines can promote the absorption of VH and improve the visual function of patients. The purpose of this review is to evaluate the efficacy and safety of Chinese medicines in the treatment of VH and inform a decision aid for the clinical encounter between patients and clinicians. Besides, it is beneficial to establish a future research agenda.

METHODS

The systematic review will include all of the randomized controlled trials on the efficacy and safety of Chinese medicines for VH. Nine electronic databases, namely PubMed, Web of Science, EMBASE, the Cochrane Library, Google Scholar, China National Knowledge Infrastructure (CNKI), Wanfang Database, China Science and Technology Journal database (VIP), and CBM, will be searched normatively on the basis of the rule of each database from the inception to August 31, 2019. We will also search registers of clinical trials, potential gray literature, and conference abstracts. There are no limits on language and publication status. The literature screening, data extraction, and quality assessment will be conducted by 2 reviewers independently. The reporting quality and risk of bias will be assessed by other 2 researchers. Standard of curative effect and total treatment efficacy rate were assessed as the primary outcome. The secondary outcomes will include the curative effect of single symptom and sign, the improvement rate of single auxiliary examination, withdrawal and reduction of western medicines in a course of treatment, maintenance of western medicines after the course of treatment, laboratory efficacy indexes. Meta-analysis will be performed using RevMan5.3 software provided by the Cochrane Collaboration.

RESULTS

This study will provide a comprehensive review based on current evidence of Chinese medicines treatment for VH in several aspects, including standard of curative effect, total treatment efficacy rate, the curative effect of single symptom and sign, the improvement rate of single auxiliary examination, withdrawal and reduction of western medicines in a course of treatment, laboratory efficacy indexes, total treatment efficacy, and safety, among others.

CONCLUSION

The conclusion of this study will provide evidence to determine whether Chinese medicines are an effective and safe intervention for patients with VH.

ETHICS AND DISSEMINATION

It is not necessary to obtain ethical approval for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences and will be shared on social media platforms.

Pediatric vitreous hemorrhage: A narrative review

Vitreous hemorrhage is one of the most common causes of sudden, painless loss of vision in adults. This is probably one of the reasons why it has been extensively studied and reported in literature. However, the same cannot be said when it comes to vitreous hemorrhage in the pediatric age group. The causes of vitreous hemorrhage in children tend to differ from those of adults. Not much data exist regarding their presentation and management. In addition to trauma, certain spontaneous causes such as pediatric tumors and congenital conditions assume importance while considering the differential diagnosis of vitreous hemorrhage in the pediatric age group. However, it is natural that the treating ophthalmologist is faced with challenges when a child presents with vitreous hemorrhage. In this narrative review, we have attempted to analyze the retrospective observational studies regarding pediatric vitreous hemorrhage reported in English literature till date. The article sheds some light on the prevailing epidemiology, management strategies employed and the visual outcome among different regions of the world.

Pediatric Eales Disease: An Indian Tertiary Eye Center Experience

PURPOSE

To report the clinical profiles, etiologies, treatment modalities, and outcomes for Eales disease in patients younger than age 16 years in India.

METHODS

Retrospective review of medical records of patients with Eales disease who had a minimum 5-year follow-up period.

RESULTS

A total of 25 eyes of 13 patients were included. Of these 13 patients, 12 (94%) had bilateral Eales disease and 11 (84.6%) were men. Mean patient age was 14.1 years (range: 11 to 16 years). Diminution of vision (36%) was the most common presenting complaint, followed by both diminutions of vision and floaters (32%). Sclerosed vessels were seen in all eyes, and 21 (84%) eyes had active periphlebitis at presentation. Neovascularization elsewhere was seen in 20 (80%) eyes and neovascularization of the optic disc was seen in 1 (4%) eye. Veno-venous shunts were found in 12 (48%) eyes, and 18 (72%) eyes had vitreous hemorrhage. All eyes received photocoagulation; 84.6% of patients received oral steroids, with 7.7% of patients treated with azathioprine and 38.4% treated with anti-tubercular therapy. Vitrectomy was performed in 36% of eyes for non-clearing vitreous hemorrhage and tractional retinal detachment. Vision improved in 7 (28%) eyes, was stable in 12 (48%) eyes, and worsened in 6 (24%) eyes. Recurrence of the disease more than five times during the 5-year follow-up period occurred in 20% of patients.

CONCLUSIONS

Recurrent vasculitis and vitreous hemorrhage in children should raise the suspicion of pediatric Eales disease. [J Pediatr Ophthalmol Strabismus. 2018;55(4):270-274.].

Bilateral proliferative retinopathy in B-cell acute lymphoblastic leukemia

A 4-year-old child with B-cell acute lymphoblastic leukemia presented with vitreous hemorrhage due to proliferative retinopathy in both eyes. Pars plana vitrectomy was performed in both eyes to clear nonresolving vitreous hemorrhage after systemic stabilization. Visual recovery was limited by the disc drag in the right eye and subfoveal exudation in the left eye. Etiopathogenesis and management of proliferative retinopathy in acute leukemias are discussed.

Bilateral Vitreous Hemorrhage in Children: Clinical Features and Outcomes

Purpose:

To determine the etiology, clinical features and outcomes of bilateral vitreous hemorrhage (VH) in children.

Methods:

This retrospective chart review was performed on patients with bilateral VH under the age of 18 at a tertiary eye care center in India. Data included demographics, details of history and ocular examination, reports of investigations, surgeries or other interventions performed, and final anatomical and visual outcomes. Patients were divided into two groups i.e., traumatic and non-traumatic (spontaneous).

Results:

The traumatic group was comprised of 37 patients including 27 male and 10 female subjects with mean age of 13.47 ± 5.31 years, the most common complaint was decreased vision (96.45%) and the most prevalent etiology was firecracker injury in 16 (43.2%) patients. Mean baseline visual acuity (VA) was 2.34 ± 1.31 logMAR which was significantly improved to 1.08 ± 0.23 logMAR (P = 0.042). The mean number of surgeries was 2.72 ± 1.43 in the traumatic VH and mean follow up period was 23.14 ± 6.54 months. The spontaneous group included 48 subjects comprised of 27 male and 21 female cases with mean age of 14.48 ± 2.03 years. The most common cause was vasculitis in 21 (43.75%) subjects including four patients with tuberculosis. Mean baseline VA was 1.97 ± 1.13 logMAR which showed a significant improvement to 0.82 ± 0.24 logMAR (P = 0.012) after mean follow up of 34.2 ± 11.2 months. Eleven patients required at least one major surgery.

Conclusion:

Vasculitis was the most common cause of spontaneous bilateral VH; traumatic VH most prevalently occurred due to firecracker injury. Final VA was better in the spontaneous group.

Vitreous hemorrhage in pediatric age group

Purpose. To identify and study causes of vitreous hemorrhage (VH) in pediatric age group and to investigate factors predicting visual and anatomical outcomes. Procedure. A retrospective review of patients aged 16 years or less with the diagnosis of vitreous hemorrhage from January 2005 until December 2010. Results. A total number of 230 patients (240 eyes) were identified. Traumatic vitreous hemorrhage accounted for 82.5%. In cases of accidental trauma, final visual acuity of 20/200 was significantly associated with visual acuity of ≥20/200 at presentation and the absence of retinal detachment at last follow-up. Patients with nontraumatic vitreous hemorrhage were significantly younger with higher rates of enucleation/evisceration/exenteration and retinal detachment at last follow-up compared to traumatic cases. Conclusion. Trauma is the most common cause of VH in pediatric age group. In this group, initial visual acuity was the most important predictor for visual outcome, and the presence of retinal detachment is a negative predictor for final good visual outcome. The outcome is significantly worse in nontraumatic cases compared to traumatic cases.
