Retinal toxicities of systemic anticancer drugs. Surv Ophthalmol 2021; 67:97-148. [PMID: 34048859 DOI: 10.1016/j.survophthal.2021.05.007] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 05/08/2021] [Accepted: 05/10/2021] [Indexed: 01/07/2023]
Abstract
Newer anticancer drugs have revolutionized cancer treatment in the last decade, but conventional chemotherapy still occupies a central position in many cancers, with combination therapy and newer methods of delivery increasing their efficacy while minimizing toxicities. We discuss the retinal toxicities of anticancer drugs with an emphasis on the mechanism of toxicity. Uveitis is seen with the use of v-raf murine sarcoma viral oncogene homolog B editing anticancer inhibitors as well as immunotherapy. Most of the cases are mild with only anterior uveitis, but severe cases of posterior uveitis, panuveitis, and Vogt-Koyanagi-Harada-like disease may also occur. In the retina, a transient neurosensory detachment is observed in almost all patients on mitogen-activated protein kinase kinase (MEK) inhibitors. Microvasculopathy is often seen with interferon α, but vascular occlusion is a more serious toxicity caused by interferon α and MEK inhibitors. Crystalline retinopathy with or without macular edema may occur with tamoxifen; however, even asymptomatic patients may develop cavitatory spaces seen on optical coherence tomography. A unique macular edema with angiographic silence is characteristic of taxanes. Delayed dark adaptation has been observed with fenretinide. Interestingly, this drug is finding potential application in Stargardt disease and age-related macular degeneration.

Abstract
Introduction Hepatitis C viral infection (HCV) represents an important health problem worldwide. Natural evolution, with its complications, remains a high cause of mortality and morbidity. Interferon (IFN) treatment, along with ribavirin (RBV), was for several years the standard of care. However, many adverse effects have been described during this therapy. We report a very elusive case of optic neuropathy. Case report We report the case of a female patient, 50 years old, who underwent pegylated IFN alfa 2B and RBV treatment for viral hepatitis C with low grade fibrosis, in a period when she was not qualified for free oral therapy (with direct acting agents according regulations in this country at that time). After 10 weeks of treatment, she experienced blurred vision and an optic neuropathy was diagnosed, attributed to the HCV. The symptoms and eye fundus alterations (hemorrhage, exudates) remitted after discontinuation of therapy. Conclusion IFN treatment remains an option for viral hepatitis, but the adverse effects are to be considered. Optic neuropathy can occur during the former standard of care HCV therapy. Patients submitted to IFN plus RBV therapy should be monitored for ocular adverse effects.

Interferon-α-induced retinopathy in chronic hepatitis C treatment: summary, considerations, and recommendations. Graefes Arch Clin Exp Ophthalmol 2018; 257:447-452.

Abstract
Interferons are cytokines that regulate the host's response to viral infection, particularly in the setting of the immunologic response to the hepatitis C virus (HCV). While the virus has the ability to evade the host's innate and specific immunity, exogenous interferon-α with combined ribavirin, treatments have been found to achieve a significant sustained viral response in subgroups of patients with chronic HCV. One of the major side effects of interferon-α is an ocular retinopathy characterized by flame-shaped hemorrhages and cotton wool spots visualized on funduscopic examination. There have been documented cases of more severe side effects including optic nerve and retinal artery damage; however, these instances are the minority. We sought to investigate the literature surrounding interferon-induced retinopathy, clinically correlate our findings with two recent cases, and provide recommendations for practitioners who continue to manage chronic HCV patients using interferon-α with combined ribavirin treatments.

Abstract
Anemia appears frequently in patients with alcoholic liver disease (ALD) but has never been linked to bilateral nonarteritic anterior ischemic optic neuropathy (NAION). A 65-year-old woman with a medical history of alcoholic cirrhosis was admitted for bilateral NAION. On admission, she was found to have a low arterial pressure and severe normocytic anemia (48 g/L). The anemia was related to chronic bleeding due to antral gastritis along with other factors associated with ALD. The applied treatment consisted of urgent transfusion followed by high doses of proton-pump inhibitors, iron and vitamin supplementation, and support in lifestyle measures. Her hemoglobin levels remained stable after 2 years but the patient still suffered from visual loss. This case highlights the link between anemia and bilateral NAION in ALD patients. The optic nerve head is prone to infarction in this context due to the vascularization characteristics of ALD. Hemoglobin levels should be monitored in ALD patients to avoid the severe complication of NAION.

Abstract
Purpose To report the first reported case of non-arteritic anterior ischemic optic neuropathy (NAION) associated with the use of Harvoni (Gilead Sciences, Foster City, CA, USA), a newly approved treatment for Hepatitis C. Observations We report a case of NAION in a hepatitis C patient who completed Harvoni therapy just prior to presentation. Harvoni was suspected to be the causative agent given a lack of NAION risk factors in an otherwise healthy young patient. Conclusions and importance NAION is an acute, painless vision loss that typically affects adults over 50. The mechanism of NAION remains uncertain although numerous associations have been identified including certain medications. Harvoni, a combination drug of ledipasvir/sofosbuvir, is a recently FDA-approved treatment for Hepatitis C. To date, however, no ophthalmological side effects have been reported with its use. Continued surveillance of patients treated with Harvoni will be needed to determine if additional events are observed in the future.

Abstract
We report the case of a 53-year-old female patient who developed bilateral sudden visual acuity loss after 15 weeks from the initiation of Peg-Interferon and Ribavirin treatment for hepatitis C. Debut was simultaneous and asymmetric, reported in the morning, at awakening. No pain or other symptom was reported by the patient. Results. At presentation, visual acuity was 0.2 in RE and 3/ 50 in LE. Pupillary reflexes were sluggish and severe dyschromatopsia was documented in both eyes (Ishihara plates). Fundus examination revealed bilateral pale optic disc edema, more prominent in LE, with splinter hemorrhages in the RNFL around the optic disk. Visual field exam demonstrated severe defects in 3 quadrants of the RE, whereas in the LE, it was impossible to perform the investigation due to VA<0.1. Neurologic evaluation was normal; other possible causes of systemic vasculitis were excluded by negative lab tests. Acute inflammatory markers (fibrinogen and ESR) and mild pancytopenia were the only documented laboratory changes in this patient. Anamnesis cleared the traditional risk factors for conventional AION (hypertension, diabetes, ischemic heart disease, and hypercholesterolemia). Cranial and orbital CT scan and MRI findings were normal. Patient was withdrawn from the Interferon and Ribavirin treatment and was administered methyl prednisolone pulse therapy (1g/ day) for 3 days, continued with oral Prednisone (60 mg/ day) tapered slowly for over 12 weeks. VA increased to 0.8 during treatment in the RE, but visual recovery in the LE was not as spectacular (0.16) as in the fellow eye. Modified latencies and amplitudes in evoked visual potentials examination during 4 months time emphasized bilateral optic atrophy. Optic nerve sufferance was amplified by a low level of vitamin B12, detected by chance at the last eye visit. Due to the general condition, dietary supplementation was not possible. Conclusion. A case of a patient with bilateral and simultaneous NAION caused by IFN and Ribavirin treatment for hepatitis C, who was also vitamin B12 deficient, was analyzed. Therefore, a combined etiology for optic atrophy was explained.

Abstract
A 13-year-old male with suprasellar cystic craniopharyngioma initially controlled with sequential subtotal resections and proton-beam irradiation was later treated with intracystic pegylated interferon α-2b due to progression and a lack of further surgical options. After initial successful control of recurrent cyst enlargement and stabilization of the ophthalmic examination, progressive and irreversible visual field loss ensued. Imaging revealed intracranial leakage from the intracystic catheter, and direct administration of interferon α-2b was discontinued. Given the recent interest in interferon α-2b, oncologists are advised to vigilantly monitor patients for signs of local toxicity that may result from unintended leakage during intracystic delivery.

Abstract
INTRODUCTION Hepatitis C is a serious viral infection, for which the current treatment is based on the combination of pegylated interferon (IFN) and Ribavirin(®). Ophthalmic complications observed with PEG-IFN are infrequent and of variable prognosis. They often include an ischemic retinopathy with typical cotton-wool spots, hemorrhage and retinal edema, and rarely acute non-arteritic anterior ischemic optic neuropathy as illustrated by our report. OBSERVATION We report the case of a 51-year-old man followed for chronic active hepatitis C, who presented in the fourth month of treatment with pegylated interferon and vidarabine with a sharp decline in visual acuity secondary to acute bilateral non-arteritic anterior ischemic optic neuropathy. The hepatitis C treatment was discontinued. His course was notable by the third week for a significant regression of papilledema with improvement in visual acuity in the right eye and no change in the left eye, remaining at counting fingers. After regressing for four years, the disease progressed to bilateral temporal optic atrophy without change in visual acuity. CONCLUSION Pegylated interferon and Ribavirin(®) are commonly used in the treatment of chronic hepatitis C. They are the source of various ophthalmologic complications of varied severity. The pathophysiology of this ocular toxicity currently remains hypothetical. Non-arteritic ischemic optic neuropathy is still a relatively rare complication with a poor functional prognosis, often requiring discontinuation of treatment. Thus, careful ophthalmologic monitoring before and during antiviral treatment of patients with hepatitis C appears necessary.

Abstract
The development of biopharmaceutical agents, including the interferons (IFN), offers new treatment options for a wide range of medical conditions. Such advancements, however, have not come without risk to patients. Optic neuropathy in the setting of IFN therapy has been previously documented and is usually attributed to anterior ischaemic optic neuropathy; however, the pathophysiology remains poorly understood. Retrobulbar optic neuropathy associated with IFN treatment has not been described in the medical literature to date. We report the case of a 38-year-old Caucasian female with refractory acute myeloid leukaemia who developed painless bilateral blurred vision within 2 weeks of commencing a course of IFN alpha-2a. Extensive clinical workup demonstrated bilateral retrobulbar optic neuropathy. We report the clinical evaluation of this first documented case and discuss the possible aetiologies of her presentation.

Abstract
BACKGROUND To describe the first reported case of toxic optic neuropathy secondary to docetaxel (Taxotere®) chemotherapy. CASE PRESENTATION A 53-year-old female presented with predominantly unilateral visual loss, but extensive bilateral visual field defects and bilateral optic nerve head swelling 2 weeks after first dose of docetaxel (Taxotere®) and trastuzumab (Herceptin®) chemotherapy for a left sided node-positive, HER2 positive breast cancer. Extensive investigation ruled out other causes of optic neuropathy. She was treated with high dose corticosteroids intravenously for 1 week then a tapering oral dose over 8 weeks. Visual field defects gradually resolved and visual acuity improved. Docetaxel chemotherapy was discontinued but targeted therapy with trastuzumab continued without further complication. CONCLUSION Docetaxel can cause a toxic optic neuropathy possibly due to an ischemic or neurotoxic mechanism at the optic nerve head. With cessation of docetaxel therapy and treatment with systemic corticosteroids, visual recovery can occur without significant residual visual deficit.

Abstract
PURPOSE To evaluate the early retinal changes and its reflection on the visual field examination in chronic hepatitis B (CHB) patients using pegylated interferon-α (PEGIFN-α) monotherapy. PATIENTS AND METHODS Thirty eyes of fifteen patients with CHB were examined prospectively for changes in the fundus examination and visual field examination (both Humphrey Perimetry and Frequency Doubling Perimetry). The patients were examined before and in 3 months intervals after starting the PEGIFN-α treatment. The changes in the fundus examination were noted and the visual field examinations, retinal nerve fiber thickness, Schirmer scores and color vision before and at 3 months of the treatment were compared. The statistical evaluation was performed with paired-t test, using SPSS 16.0 Inc. (Chicago, IL). RESULTS The mean age of the 15 patients (seven male, eight female) was 52.5 ± 12.4 years. There was no significant retinal change in none of the patients. Neither the visual field examination with Humphrey Field Analyzer nor the Frequency Doubling Perimetry results has demonstrated any significant change during 3 months follow-up. There was a statistically significant increase in the retinal nerve fiber layer (RNFL) thickness; while Schirmer test scores for dry eye assessment was significantly decreased. CONCLUSION PEGIFN-α monotherapy, which is used for treatment of CHB, may cause some changes in the thickness of RNFL that may necessitate the close follow-up for further morphological changes of the optic disc in these patients.

Abstract
A 58-year-old white man presented with a second episode of vision loss in the same eye. Diagnostic evaluations conducted at each episode were unrevealing for an underlying etiology, and a presumptive diagnosis of recurrent non-arteritic anterior ischemic optic neuropathy (NAION) was made. The evaluation of recurrent NAION is discussed.
