β-Adrenoreceptors as Therapeutic Targets for Ocular Tumors and Other Eye Diseases-Historical Aspects and Nowadays Understanding. Int J Mol Sci 2023; 24:ijms24054698. [PMID: 36902129 PMCID: PMC10003534 DOI: 10.3390/ijms24054698] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 02/21/2023] [Accepted: 02/24/2023] [Indexed: 03/05/2023] Open
Abstract
β-adrenoreceptors (ARs) are members of the superfamily of G-protein-coupled receptors (GPCRs), and are activated by catecholamines, such as epinephrine and norepinephrine. Three subtypes of β-ARs (β1, β2, and β3) have been identified with different distributions among ocular tissues. Importantly, β-ARs are an established target in the treatment of glaucoma. Moreover, β-adrenergic signaling has been associated with the development and progression of various tumor types. Hence, β-ARs are a potential therapeutic target for ocular neoplasms, such as ocular hemangioma and uveal melanoma. This review aims to discuss the expression and function of individual β-AR subtypes in ocular structures, as well as their role in the treatment of ocular diseases, including ocular tumors.

The Effectiveness of Propranolol in Managing Hemorrhagic Choroidal and Exudative Retinal Detachment following Ahmed Glaucoma Valve Implantation in Sturge-Weber Syndrome: Case Report and Literature Review. Case Rep Ophthalmol 2021; 12:859-869. [PMID: 34899259 PMCID: PMC8613549 DOI: 10.1159/000518805] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 07/27/2021] [Indexed: 11/19/2022] Open
Abstract
Sturge-Weber syndrome (SWS) is a congenital neurological disorder that is characterized by hamartomas involving the skin, brain, and eyes and marked by the presence of the facial port-wine stain, which consequently leads to various ocular complications. Among all ocular comorbidities, glaucoma is the most frequently witnessed in SWS patients with a prevalence of 30%–70%. If glaucoma is refractory to conventional medical management, surgical intervention can be considered. Common complications of glaucoma procedures in SWS are choroidal detachment and suprachoroidal hemorrhage. Moreover, we report a 6-year-old girl, known case of unilateral congenital glaucoma secondary to SWS. Despite being on maximal antiglaucoma drops and undergoing multiple surgical interventions, the patient had uncontrolled intraocular pressure of her right eye. A decision to proceed with Ahmed glaucoma valve implantation (AGVI) to the right eye was made. In the immediate postoperative period, the patient developed hemorrhagic choroidal detachment and exudative retinal detachment. A trial of oral propranolol (1.5–2 mg/kg/day) was then initiated for 4 months. After 30 days from oral propranolol course initiation, we started noticing a significant improvement of the hemorrhagic choroidal and exudative retinal detachment. Spontaneously, a marked reduction in subretinal fluid and suprachoroidal hemorrhage was also seen. Thus, the improvement was correlated with the propranolol therapy. Here, we report a significant improvement of the postoperative complications of AGVI in a patient with SWS, following 4 months of oral propranolol course (1.5–2 mg/kg/day). Further studies are needed to determine the dosage, duration, and optimal mechanism by which propranolol works in this situation.

Abstract
Importance Choroidal hemangiomas are defined by a thickened choroid owing to vessel overgrowth, which may increase the intraocular pressure and lead to glaucoma. Choroidal hemangioma and glaucoma often co-occur in patients with Sturge-Weber syndrome, a rare neurocutaneous disorder characterized by capillary malformations. Objective To determine whether the mutation found in most capillary malformations, GNAQ R183Q (c.548G>A), was present in the choroidal hemangioma of a patient with Sturge-Weber syndrome. Design, Setting, and Participant Using laser-capture microdissection, choroidal blood vessels were isolated from paraffin-embedded tissue sections, and genomic DNA was extracted for mutational analysis. Choroidal sections were analyzed in parallel. A patient with choroidal hemangioma and Sturge-Weber syndrome who had undergone enucleation was analyzed in this study at Boston Children's Hospital. Negative controls were choroidal tissue from an eye with retinoblastoma and unaffected lung tissue; brain tissue from a different patient with Sturge-Weber syndrome served as a positive control. Infantile hemangioma was analyzed as well. Data were analyzed in 2018. Main Outcomes and Measures The mutant allelic frequency of GNAQ R183 and GNAQ Q209L/H/P was determined by droplet digital polymerase chain reaction on isolated genomic DNA. The infantile hemangioma marker glucose transporter-1 was visualized by immunofluorescent staining of tissue sections. Results The GNAQ R183Q mutation was present in the patient's choroidal vessels (21.1%) at a frequency similar to that found in brain tissue from a different patient with Sturge-Weber syndrome (25.1%). In contrast, choroidal vessels from a case of retinoblastoma were negative for the mutation (0.5%), as was lung tissue (0.2%). The patient's choroidal tissue was negative for the 3 GNAQ mutations associated with congenital hemangioma and for the infantile hemangioma marker glucose transporter-1. Conclusions and Relevance The results suggest that a more accurate description for choroidal hemangioma in patients with Sturge-Weber syndrome is choroidal capillary malformation. This finding may explain why propranolol, used to treat infantile hemangiomas, has been largely ineffective in patients with choroidal hemangioma. Further studies are needed to corroborate this finding.

Circumscribed Choroidal Hemangioma: Visual Outcome in the Pre-Photodynamic Therapy Era versus Photodynamic Therapy Era in 458 Cases. Ophthalmol Retina 2019; 4:100-110. [PMID: 31611094 DOI: 10.1016/j.oret.2019.08.004] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2019] [Revised: 07/24/2019] [Accepted: 08/12/2019] [Indexed: 11/23/2022]
Abstract
PURPOSE To analyze visual outcomes after treatment of choroidal hemangioma in the pre-photodynamic therapy (PDT) era versus PDT era. DESIGN Retrospective, comparative case series. PARTICIPANTS A total of 458 patients with circumscribed choroidal hemangioma. METHODS Comparison of hemangioma managed in the pre-PDT (1967-2001) era versus PDT (2002-2018) era. MAIN OUTCOME MEASURE Visual acuity outcome. RESULTS A total of 458 tumors were treated over this 51-year period. A comparison (pre-PDT [n = 220 cases] vs. PDT [n = 238 cases]) revealed PDT era patients were of older mean age (48.9 vs. 53.8 years, P = 0.002) and were more likely to have systemic hypertension (17.7% vs. 33.8%, P < 0.001), tumor location in the macula (57.4% vs. 67.5%, P = 0.01), subretinal fluid on OCT (33.3% vs. 70.7%, P = 0.01), and greater extent of overlying lipofuscin (P = 0.001). Findings of tumor basal diameter and thickness and fluorescein and indocyanine green angiography were no different in the 2 eras. Treatment (pre-PDT vs. PDT) included argon laser photocoagulation (42.1% vs. 0.4%), PDT (0% vs. 43.8%), transpupillary thermotherapy (0% vs. 0.4%), plaque radiotherapy (7.0% vs. 5.2%), external beam radiotherapy (1.4% vs. 1.3%), enucleation (0.9% vs. 0.4%), and observation (48.6% vs. 47.6%). After treatment, patients in the PDT era demonstrated better mean logarithm of the minimum angle of resolution visual acuity (1.28 vs. 0.51, P < 0.001) (Snellen equivalent 20/400 vs. 20/63, P < 0.001). Final visual acuity was ≥20/40 for those with entering vision of ≥20/40 (59.6% vs. 74.7%, P = 0.001) and for those with entering vision of 20/50-20/200 (25.4% vs. 47.3%, P < 0.001). CONCLUSIONS Management of choroidal hemangioma in the PDT era has allowed for significantly better visual outcome compared with the pre-PDT era, with mean final visual acuity of 20/400 (pre-PDT era) versus 20/63 (PDT era).

Abstract
BACKGROUND Oral propranolol has become first-line intervention for problematic infantile hemangioma (IH) that is not amenable to topical or intralesional therapies. Consensus data supporting its efficacy for other vascular anomalies does not exist. The purpose of this study was to determine the frequency and causes of propranolol use for vascular lesions other than IH. METHODS Referrals to our Vascular Anomalies Center between 2008 and 2017 were reviewed for patients treated with propranolol at an outside institution. Patient history, photographs, imaging studies, and/or histopathology were evaluated by an interdisciplinary team to diagnose the vascular anomaly. Our center's diagnosis was compared to the referral diagnosis to categorize patients into 3 groups: Group 1 (patients were appropriately labeled with an IH); Group 2 (individuals were erroneously diagnosed with IH); and Group 3 (subjects were diagnosed with a vascular anomaly other than IH). RESULTS Two hundred thirty-six patients met inclusion criteria. Group 1 (39%; n = 91) had an IH and were treated appropriately. Group 2 (20%; n = 49) was misdiagnosed with IH and incorrectly received propranolol. Group 3 (41%; n = 96) was given propranolol to treat another vascular anomaly. Propranolol did not have efficacy for vascular anomalies other than IH. CONCLUSIONS Propranolol commonly is used to treat lesions other than IH; misdiagnosis of a lesion as IH is a common cause. Propranolol should be used with caution to treat other types of vascular anomalies because patients are subjected to the risks of the drug without data supporting its efficacy.

Results of external beam radiotherapy for diffuse choroidal hemangiomas in Sturge-Weber syndrome. Eye (Lond) 2018; 32:1067-1073. [PMID: 29403070 DOI: 10.1038/s41433-018-0024-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2017] [Revised: 10/04/2017] [Accepted: 11/15/2017] [Indexed: 12/17/2022] Open
Abstract
PURPOSE The Sturge-Weber Syndrome (SWS) is a phacomatosis which include facial nevus flammeus, glaucoma, diffuse choroidal hemangioma, and leptomeningeal hemangiomatosis. External beam radiotherapy (EBRT) using photons was used to treat retinal detachment. We investigate the anatomical and functional results in a long-term basis. METHODS Retrospective review of SWS patients treated by EBRT (20 Gy in 10 fractions) for an exudative diffuse choroidal hemangioma. Visual acuity, B-scan tumor thickness, size of retinal detachment, intra-ocular pressure, and hypotonic treatment were collected before EBRT, 1 year after, and at the latest news. RESULTS Twenty-five patients (26 eyes) were treated between 2001 and 2014. Retinal detachment including the macula was found among twenty-six eyes before treatment. The average follow-up time was 47 months. The mean tumor thickness was initially 4.5 mm, 2.8 mm at first year, and 2.7 mm at the last visit. The retina was reattached at the last visit for all eyes except two. The visual acuity was stable or better for 20 eyes (p = 0.02). Four patients developed mild cataract during the follow-up. CONCLUSION EBRT using 20 Gy in 10 fractions is efficient, decreases tumor thickness, reattaches the retina, and stabilizes visual acuity. In the long term, retinal reattachment allows ocular conservation by preventing phthisis bulbi.

Abstract
Aim. To report a case of bilateral Sturge-Weber and Phakomatosis pigmentovascularis with secondary glaucoma in a child. Method. Case report. Results. A 4-year-old male child was referred to us for control of intraocular pressure (IOP). Sleeping IOP was 36 mm Hg in right eye and 28 mm Hg in the left eye. The sclera of both the eyes showed bluish black pigmentation—melanosis bulbi. Fundus examination of both eyes showed diffuse choroidal hemangiomas with glaucomatous cupping. Nevus flammeus was present on both sides of face along all the 3 divisions of trigeminal nerve with overlying hypertrophy of skin and on left forearm. Nevus fuscocaeruleus was present on upper trunk. All skin lesions were present since birth and were stationary in nature. CT scan of head revealed left-sided cerebral atrophy. Intraocular pressure was controlled after treatment with topical antiglaucoma medications. Pulsed Dye Laser has been advised by dermatologist for skin lesions. Patient has been advised for regular follow-up. Conclusion. The two overlapping dermatological disorders and their association with glaucoma are a rare entity. Management should be targeted both for dermatological and eye conditions.

Abstract
PURPOSE The purpose of this study was to evaluate inter-rater reliability and validity of a proposed functional outcome battery for clinical trials in children with Sturge-Weber syndrome (SWS). METHODS Ten children were evaluated twice on the same day using a series of functional outcome measures selected for sensitivity to the range of age and function of children with SWS: Modified Rankin Scale, Pediatric Evaluation of Disability Index, Modified House Functional Classification, and a modified version of the Erhardt Developmental Prehension Assessment. Inter-rater reliability was calculated, and criterion validity was explored through correlations with the Sturge-Weber Syndrome-Neurological Rating Score (SWS-NRS). RESULTS Inter-rater reliability was high across all measures. Correlations were identified between the SWS-NRS and the study measures. CONCLUSIONS The proposed battery of functional outcome measures captures child's functioning at the levels of impairment, activity and participation and is robust to evaluation by different raters and across sessions on the same day. This battery is expected to be sensitive to treatment-related changes in qualitative patterns of hand use, functional skills, and/or change in independence in daily living.

Abstract
Sturge-Weber syndrome (SWS) is a congenital, sporadically occurring, neurocutaneous syndrome that presents classically with port-wine stain, leptomeningeal angiomas, and glaucoma. The systemic implications of SWS are vast and involve not only ophthalmic manifestations but also dermatologic, neurologic, and oral manifestations. Neuroimaging, in particular, plays an important role in the diagnosis and management of this disease. Recent discoveries have been made regarding the genetic pathogenesis of SWS. In addition, recent advances have been made in the management of the 2 most common ophthalmic manifestations of SWS: diffuse choroidal hemangioma and glaucoma. Despite these new contributions to the field, many challenges still remain. The management of diffuse choroidal hemangioma is wide ranging and includes photodynamic therapy, brachytherapy, radiotherapy, and antivascular endothelial growth factor injections, but all have had limited or varied success. Although there have been recent advances in knowledge and technique, the management of glaucoma is extremely complex, given the high surgical risks for complications and a poor response rate to medical therapy. Further studies are critical to maximize our knowledge of this difficult disease.

Abstract
PURPOSE To report the effect of oral propranolol on intraocular pressure (IOP) in infants newly diagnosed with unilateral Sturge-Weber syndrome (SWS) glaucoma receiving no other treatment. METHODS This was a prospective, nonrandomized interventional case series. Four infants presenting with unilateral SWS glaucoma with no prior treatment were treated with oral propranolol at a dose of 2 mg/kg and followed thereafter. RESULTS Propranolol had a temporary IOP-lowering effect in 3 of 4 children after 1 week of treatment. This effect diminished thereafter and 3 of 4 children required additional medical or surgical treatment. CONCLUSIONS Oral propranolol has a temporary effect on IOP in SWS glaucoma and is not effective as a single treatment in this syndrome, yet can serve to delay surgical treatment for a short period of time. In one case, the glaucoma was well-controlled on this medication.
