Elevated Choroidal Thickness and Central Serous Chorioretinopathy in the Fellow Eyes of Patients with Circumscribed Choroidal Hemangioma

Management of circumscribed choroidal hemangioma at a tertiary care center

PURPOSE

To review long-term outcomes of circumscribed choroidal hemangioma (CCH).

METHODS

Hospital charts of all CCH cases diagnosed from 2008 to 2019 were retrospectively reviewed.

RESULTS

All 172 patients were managed with either observation, transpupillary thermotherapy, argon laser photocoagulation, photodynamic therapy, plaque brachytherapy or stereotactic radiosurgery. The most common 3 modes of management were clinical observation (30.2%), transpupillary thermotherapy (52.9%) and argon laser photocoagulation (8.7%). Median follow-up time was 10 months (range: 3, 160). Anatomical outcomes were stable in 87.1% of observation group and improved in 60.5% of thermotherapy group. Quantified optical coherence tomography angiography findings showed statistical differences in vascular and perfusion densities in fellow eyes of hemangioma patients.

CONCLUSION

Circumscribed choroidal hemangioma can be treated in various ways. Transpupillary thermotherapy is an anatomically effective treatment in selected cases. The diagnosis of CCH may have vascular implications in fellow eyes of the patients.

New insights on circumscribed choroidal hemangioma: "bench to bedside"

Circumscribed choroidal hemangioma is a rare vascular hamartoma of the choroid, presenting as a red-orange mass at the posterior pole on fundoscopic examination. Despite its benign origin, associated complications such as subretinal fluid, serous retinal detachment, retinoschisis and neovascular glaucoma may lead to serious visual impairment in more than half patients. Because of its similarity to amelanotic choroidal melanoma and choroidal metastasis, differential diagnosis is still challenging for specialists. Multimodal imaging such as ultrasonography, fluorescein angiography, indocyanine green angiography, optical coherence tomography, and optical coherence tomography angiography guides the clinician to the correct diagnosis and the proper follow-up. Treatment is indicated in symptomatic cases in order to resolve exudation and improve visual acuity. Treatment options include photocoagulation, transpupillary thermotherapy, radiation therapy, photodynamic therapy and anti-vascular endothelial growth factor therapy. Currently, photodynamic therapy is the treatment of choice due to its effectiveness and safety. The purpose of this review is to describe the latest knowledge in the etiopathogenesis of the circumscribed choroidal hemangioma, the most recent multimodal imaging findings, and the available treatment options.

Ultrasound in ocular oncology: Technical advances, clinical applications, and limitations

Due to its accessibility and ability for real-time image acquisition of ocular structures, ultrasound has high utility in the visualization of the eye, especially in ocular oncology. In this minireview, we summarize the technical rationale and applications of ultrasound modalities, A-scan, B-scan, high-frequency ultrasound biomicroscopy (UBM), and Doppler measurement. A-scan ultrasound uses a transducer of 7-11 MHz, making it useful for determining the echogenicity of ocular tumors (7-8 MHz) and measuring the axial length of the eye (10-11 MHz). B-scan ultrasound operates at 10-20 MHz, which can be used for measuring posterior ocular tumors while UBM operates at 40-100 MHz to evaluate anterior ocular structures. Doppler ultrasonography allows for the detection of tumor vascularization. While ultrasonography has numerous clinical applications due to its favorable penetration compared with optical coherence tomography, it is still limited by its relatively lower resolution. Ultrasound also requires an experienced sonographer due to the need for accurate probe localization to areas of interest.

Occurrence of circumscribed choroidal hemangioma accompanied by polypoidal choroidal vasculopathy and branch retinal vein occlusion: a case report

BACKGROUND

Circumscribed Choroidal hemangioma (CCH) is a kind of hamartoma that is caused by congenital vascular malformation. And, polypoidal choroidal vasculopathy (PCV) is an exudative maculopathy. There is no literature indicating that there is a correlation between the occurrences of CCH and PCV.

CASE PRESENTATION

A 66-year-old male presented with decreased vision of his left eye for 4 years. Fundus photograph showed that the branches of blood vessels at the supratemporal retina were occluded in white lines, an orange lesion could be seen in the subnasal retina and mottled, yellowish white lesions were accompanied by punctate hard exudation in the macular in the left eye. The Fundus autofluorescence (FAF), fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and Spectral domain optical coherence tomography (OCT) were done. There was a diagnosis of CCH, PCV and branch retinal vein occlusion accompanied with retinoschisis of the left eye.

CONCLUSION

This article reports on a case of an elderly male Chinese patient with CCH and PCV accompanied by branch retinal vein occlusion with retinoschisis in the left eye. The common lesions are choroidal vascular abnormalities. Whether hypertension is related to CCH, PCV and branch retinal vein occlusion remains to be further studied.

Ganglion Cell Loss in the Course of Central Serous Chorioretinopathy

INTRODUCTION

Central serous chorioretinopathy (CSCR) as a clinical entity is potentially damaging and may significantly affect retinal morphology and function, especially in the chronic form. Our study aimed to determine the amount of deficit of best corrected visual acuity (BCVA) and individual retinal layers, including ganglion cells, in different types of CSCR and with reference to its duration.

METHODS

The retrospective analysis included 69 eyes of patients with resolved CSCR managed in Dobry Wzrok Ophthalmological Clinic between 1 January 2019 and 30 June 2022. The diagnosis of CSCR was based on the criteria outlined by the Central Serous Chorioretinopathy International Group. The analysis included data obtained from medical history, BCVA testing, and spectral domain optical coherence tomography (SD-OCT) measurements, with specific thickness values for individual retinal layers. The results were compared among affected eyes, unaffected fellow eyes, and healthy controls.

RESULTS

BCVA values were significantly lower in acute (0.08 ± 0.12 logMAR) and chronic (0.26 ± 0.19 logMAR) cases versus controls (0.0 logMAR). The thickness of all retinal layers (central subfoveal thickness, CST; inner retina with ganglion cell complex, GC; outer retina, ORT; and photoreceptor outer segments, POS) and macular volume (MV) were significantly decreased in chronic eyes versus controls (p < 0.01). Acute eyes had significant thinning of the outer retina and POS only compared to control eyes (p < 0.01). The amount of deficit in CST, ORT, GC, and MV was strongly correlated with poorer BCVA (p < 0.001), and the deficit of CST, ORT, and GC was correlated with disease duration (p < 0.05). The subfoveal choroidal thickness was significantly greater in affected and fellow eyes versus controls (p < 0.001).

CONCLUSION

Damage to the outer retina and photoreceptors occurs early in the course of CSCR, with a deficit in ganglion cells noted adjunctively in chronic forms of the disease. Further studies are required to precisely determine correlation between visual loss in CSCR and deficits in individual retinal layers.

Multimodal Imaging Characteristics of Circumscribed Choroidal Hemangioma Accompanying with Central Serous Chorioretinopathy: A Case Report

A 42-year-old man presented with a temporal visual field defect in his right eye. His history revealed systemic steroid use before onset of his complaints. Multimodal imaging techniques including ultrasonography, fluorescein angiography, indocyanine green angiography, and optical coherence tomography angiography (OCTA) suggested the presence of circumscribed choroidal hemangioma (CCH) accompanying with central serous chorioretinopathy (CSCR) in the right eye, which might have worsened with systemic steroid treatment. CCH may rarely present with accompanying CSCR. Besides, OCTA is a non-invasive reliable method for the diagnosis of CCH in terms of visualizing vascular features of tumor.

Long-term follow-up and "double layer sign" in patients affected by circumscribed choroidal hemangioma

BACKGROUND

Photodynamic therapy has revolutionised the treatment of circumscribed choroidal hemangiomas. The aim of this report is to report the long-term follow-up of patients affected by circumscribed choroidal hemangioma treated using photodynamic therapy.

MATERIALS AND METHODS

We retrospectively reviewed patients affected by circumscribed choroidal hemangioma examined at the Retinal Medical Department at the Eye Clinic in Florence. We studied circumscribed choroidal hemangiomas treated using photodynamic therapy with at least 1 follow-up examination. Verteporfin was administered intravenously for 10 min (6 mg/m2 body surface area). After infusion (5 min), a 689 nm laser was applied with a light dose of 50 J/cm2.

RESULTS

Ten eyes of 10 patients with circumscribed choroidal hemangioma who underwent Photodynamic therapy were included in our series (2 females and 8 males; average age at diagnosis 47.8 ± 9.3 yrs.; age range: 27-56 years). Five patients (5/10; 50 %) received only the photodynamic treatment whereas 5 patients (5/10; 50 %) also received other treatments (laser photocoagulation, intravitreal injection). On average, the patients received 2 photodynamic treatments (range 1-4). Four patients (4/10, 40 %) had a > 5-year follow-up; (average 4.5 ± 3.7 yrs. range 6 months - 10 years). In 2 patients we identified the "double layer sign" at the optical coherence tomography examination on circumscribed choroidal hemangioma.

CONCLUSIONS

In our series, photodynamic therapy was a safe and effective treatment for circumscribed choroidal hemangioma during long-term follow-up. The double layer sign, which can be detected in several choroidal pathologies, suggests common pathogenetic mechanisms for circumscribed choroidal hemangiomas and central serous chorioretinopathy/polypoidal choroidopathy spectrum disease.

Circumscribed choroidal haemangioma: Indocyanine green angiography features on scanning laser ophthalmoscopy versus traditional digital fundus photography

BACKGROUND AND OBJECTIVE

Circumscribed choroidal haemangioma (CCH) has several characteristic clinical and angiographic features. We aimed to compare indocyanine green angiography (ICG) findings of CCH captured on a traditional digital camera system (DCS) to newer scanning laser ophthalmoscopy (SLO) platforms.

STUDY DESIGN/MATERIALS AND METHODS

A total of 35 patients over a 10-year period diagnosed with CCH using ICG were included (18 imaged with DCS and 17 with SLO).

RESULTS

On early ICG frames, intrinsic vessels were apparent in two-thirds (12/18; 67%) of the DCS group compared with all of eyes in the SLO group (p = 0.020). In addition, at maximal hyperfluorescence, most eyes imaged with DCS had a feathery appearance (16/18; 89%) compared with those in the SLO group which all (17/17; 100%) displayed a granular appearance (p < 0.001). The presence of hot spots at maximal hyperfluorescence was also more common in the SLO group (12/17; 71%) versus the DCS group (0/18; 0%) (p < 0.001). Finally, intrinsic vessels and vascular loops could be identified throughout the entire duration of the ICG in 100% of the SLO cases (17/17) versus only 11% (2/18) of DCS cases (p < 0.001).

CONCLUSIONS

The visualization of intrinsic vessels, vascular loops, and "hot spots" in CCH is significantly enhanced with SLO compared with DCS. Many characteristic mid-late angiographic findings of CCH are more optimally visualized on SLO which may negate the need for late frames (>30 min) without compromising diagnostic accuracy.

Optical coherence tomography angiography of flat irregular pigment epithelial detachments in central serous chorioretinopathy

Background

To identify and analyse the character and relationship between flat irregular pigment epithelial detachment feature (FIPED), choroidal thickness and choroidal neovascularisation (CNV) network seen on optical coherence tomography angiography (OCTA) in eyes with central serous chorioretinopathy (CSCR) in Chinese patients.

Method

In the present study, 152 eyes of 144 Chinese patients, who were previously diagnosed with CSCR, were retrospectively studied. Patients’ baseline characteristics, the course of CSCR, best-corrected visual acuity, the pattern of CNV on OCTA, FIPED and choroidal thickness detected by enhanced depth imaging-OCT (EDI-OCT) were analysed.

Results

It was disclosed that 7.23% of CSCR patients had CNV. Age and the course of CSCR were found to be correlated with the occurrence of CNV. Among the eyes with CNV network (11 eyes), 100% of them had FIPED, whereas, among the eyes without CNV (141 eyes), 18.04% had FIPED. The maximum width and en-face area of PED were greater in the CNV group compared with that in the non-CNV group (p<0.001). It also was revealed that female gender and a poor vision were risk factors for CNV in eyes with CSCR. The choroidal thickness detected by EDI-OCT was also statistically significant between eyes with CNV and eyes without CNV. The patients who have CNV complicated with FIPED are susceptible to have low vision.

Conclusion

The present research demonstrated that the majority of CNV cases were linked to FIPED, and the thinner thickness of choroid. The greater width and en-face area of PED may point towards the presence of an underlying CNV network.
