Abstract
Ocular complications of antineoplastic agents can have a profound effect on the quality of life of cancer patients. New oncologic treatments like monoclonal antibodies, immunotherapies, antibody-drug conjugates, checkpoint inhibitors and growth factor receptors have resulted in increased ocular complications. These ocular complications differs in respect to distinct mechanisms of actions and lead to significant challenges in the management of cancer patients. In this review, we reviewed literature, clinical studies and cases detailing ocular complications due to administration of antineoplastic agents and emphasized the need for communication between oncologists and ophthalmologists toward early detection and management of ocular complications.

Abstract
PURPOSE This study aimed to determine if the corneal endothelium was affected by chemotherapy. METHODS Chemotherapy patients were recruited to undergo specular microscopy before treatment and again at 1- and 2-year follow-up visits. One eye per patient, per follow-up, was selected for comparison to baseline. RESULTS Forty-six volunteers completed baseline and at least one follow-up assessment. From 51 eyes, there was no significant change in endothelial cell density for 41 eyes assessed at one year (MD = 0.73%, 95% CI -1.33 to 2.78%) and 18 eyes at two years (MD = 0.31%, 95% CI -3.53 to 4.15%). CONCLUSION Although other studies have shown that chemotherapy can adversely affect the corneal epithelium, this study showed no measurable change in endothelial cell density.

Abstract
Purpose To examine long-term data on optic disc drusen (ODD) from an outpatient hospital series that indicated more cases with advanced visual field constriction than is apparent from other clinical reports. The underlying pathophysiology is discussed, also with regard to enlarged blind spot, which, in view of the small disc at risk, may seem a paradox. Methods This is an observational retrospective study on an eye clinic series (n = 49), focusing on visual acuity, kinetic/static perimetry, and longitudinal trends, to include the question of eventual visual incapacity. Results Forty-nine patients (32 female and 17 male; bilateral ODD in 45) aged 5-76 years (median age 29 years for both sexes) were included in the study. Observation time was 1-54 years, with serial data recorded over at least 3 years in 25 patients. Visual field defects were found in 32 patients, with ODD considered responsible for the visual field defects demonstrated. Advanced unilateral concentric constriction (for the largest Goldmann object) was recorded in 10 patients, and bilaterally in 2. With regard to nonexplanatory side diagnoses, 2 patients had pituitary adenoma, 1 had a cavernous sinus meningioma, and 1 had neurosurgery for an arachnoid cyst. Conclusions We found more cases of marked visual field constriction than reported in other clinical series. A few such cases appeared acute and vascular, but the main trend was clinically quiet over time. All 49 patients could manage visually in daily life.

Abstract
Strategies for the treatment of childhood cancer have changed considerably during the last 50 years and have led to dramatic improvements in long-term survival. Despite these accomplishments, CNS tumors remain the leading cause of death in pediatric oncology. Astrocytic tumors form the most common histologic group among childhood brain tumors. They are a heterogeneous group that from a practical therapeutic point of view can be subdivided into low-grade astrocytomas (LGA), optic pathway gliomas (OPG), high-grade astrocytomas (HGA), and brainstem gliomas (BSG). This article focuses on the practical application of treatments that lead to long-term survival, improved quality of life, and reduced long-term complications. Improvement in therapy has led to better outcomes for patients with LGA and OPG. Careful follow-up without any treatment is indicated for a small percentage of patients diagnosed with LGA with an indolent course including children with neurofibromatosis type 1 (NF1). Surgery is the main recommended treatment for children with resectable LGA. Radiation therapy is generally recommended for children with progressive LGA, or after failure of chemotherapy, accomplishing tumor control at 10 years in over 60% of patients. Cytotoxic chemotherapy is usually reserved for children who have had treatment failure with surgery and radiation therapy. It is also offered for children who are too young to be treated with radiation or to defer or avoid radiotherapy. Carboplatin and vincristine achieve 5% complete and 28% partial responses but the use of vincristine is criticized due to poor penetration of the CNS. A regimen of tioguanine, procarbazine, mitolactol, lomustine, and vincristine is frequently administered as an alternative to carboplatin and vincristine in LGA. The introduction of temozolomide has allowed better responses, including a 24% complete response rate compared with 0-5% complete response rates with the previous regimens. OPG are usually histologically LGA, and are treated with similar chemotherapy regimens. OPG is the most common type of brain tumor associated with NF1. Tumor growth in some of these patients is slow with no treatment recommended for an extended period of time. The prognosis for children with the remaining types of astrocytomas remains poor. Surgical resection is typically the first step in the treatment of HGA followed in older children by radiation therapy. The data regarding chemotherapy are mixed. Combination chemotherapy before or after radiation, including cisplatin, carmustine, cyclophosphamide, and vincristine or carboplatin, ifosfamide, cyclophosphamide, and etoposide has provided disappointing results. Clinical trials with temozolomide and agents directed against single targets have not shown substantially better results, but it is hoped that currently conducted studies will provide better outcomes. Diffuse intrinsic BSG are among the most difficult-to-treat brain tumors. Surgical treatment is not recommended for diffuse intrinsic BSG and standard radiation therapy is typically given in children aged >3 years. None of the numerous chemotherapy regimens, including temozolomide, has provided a significant response rate or an improvement in survival. It is expected that newer agents affecting multiple targets such as AEE-788 and antineoplastons, and combinations of single-targeted agents with chemotherapy will provide better results. Careful evaluation of histology, location of the tumor, patient age, and consideration of treatment-related morbidity play an important part in selecting between clinical observation, surgery, radiation, chemotherapy, or investigational agents. The goals of treatment for astrocytic tumors should extend well beyond objective responses and increased survival. Improvement of quality of life is an equally important objective of treatment. Radiation therapy and chemotherapy result in serious late toxicities.

Abstract
BACKGROUND Systemic anticancer therapies can produce acute and chronic organ damage, but the eye is usually considered a protected site. Nonetheless, the oculo-visual system has a potentially high degree of sensitivity to toxic substances. Ocular toxicity induced by cancer chemotherapy includes a broad spectrum of disorders, reflecting the unique anatomic, physiologic, and biochemical features of this essential organ. METHODS A review of the literature regarding the ocular toxicity of chemotherapeutic agents, hormonal agents, biologic agents, and high dose chemotherapy with allogeneic and autologous bone marrow transplantation was conducted. RESULTS Ocular toxicity induced by anticancer chemotherapy is not uncommon. The development of more aggressive regimens as well as new agents and combination chemotherapies have resulted in a significant increase of reported cases of chemotherapy-induced ocular side effects. In most instances, the mechanisms of ocular toxicity continue to be poorly understood. CONCLUSIONS Ocular toxicities induced by chemotherapeutic agents are generally not preventable; therefore, clinicians must be aware of potential vision-threatening complications. Prompt consultation with an ophthalmologist can lead to early detection, proper diagnosis, and appropriate therapeutic measures. Dose reduction or discontinuation of incriminated drugs may help in reducing the severity and the duration of side effects.

Abstract
The optic nerve, ontogenetically part of the central nervous system, is surrounded by subarachnoidal cerebrospinal fluid (CSF) and dura mater. Because of the connection with the intracranial subarachnoidal space, CSF pressure variations influence the optic nerve sheath (ONS) diameter. Histologic studies revealed a segment of the optic nerve in which maximal diameter fluctuations could be expected, namely the bulging dura mater region approximately 3 mm behind the papilla. Twenty preparations of optic nerves obtained post mortem were examined sonographically before and after dilatation of the ONS, by means of measurement from three different projections. After gelatine-induced widening of the subarachnoidal space, the mean diameter increased by 60% at 3 mm behind the optic nerve head, but only by 35% at 10 mm distance. Independent measurements by two examiners correlated highly, which indicates excellent reproducibility of the sonographic measurements. The optimal experimental scanning position was at a right angle to the optic nerve (longitudinal section). Under clinical conditions, however, only axial sections can be obtained using anterior probe positions with transbulbar sound directions. Using such axial projections the 3 mm position proved reliably reproducible. The reduced resolution of the optic nerve itself, allowing it to be distinguished from its surrounding sheath, proved to be somewhat disadvantageous from this projection angle.

Abstract
Thirty cases of gliomas treated by surgery, radiotherapy and intra-arterial (IA) ACNU were reviewed with a focus on the late side-effect known as leukoencephalopathy. All cases were classified into three groups; remission (10 cases), regrowth (15 cases) and leukoencephalopathy (5 cases) from their outcome. The average total doses of IA ACNU were 49.8 mg/sqm body surface area in the remission group, 157.3 mg/sqm in the regrowth group and 203.1 mg/sqm in the leukoencephalopathy group. There were significant differences in the total IA ACNU doses between the remission group and both regrowth and leukoencephalopathy groups, while no significant differences were noticed in the dose of radiation given. There was a correlation between the total dose of IA ACNU and the occurrence of leukoencephalopathy. An autopsy of a typical case of leukoencephalopathy revealed various degrees of myelin breakdown and thickening of arterial walls, which probably manifested progressive dementia accompanied by urinary incontinence and gait disturbance.

Abstract
Gliomas of the anterior visual pathway are rare orbital lesions accounting for 65% of all intrinsic optic nerve tumors. These lesions occur principally among children in the first decade of life. They appear to be true neoplasms that characteristically show early growth, followed by stability in many patients. Visual prognosis is fair, and the outlook for life depends upon tumor location. When initially confined to the optic nerve alone, overall mortality is about 5%. Once the hypothalamus is involved, mortality rises sharply to over 50%. With involvement of the chiasm or hypothalamus, no form of therapy significantly alters the final outcome. Because of their indolent course, gliomas may be followed conservatively when confined to the optic nerve. In these cases, surgery is indicated only when blindness and pain or severe proptosis intervene. However, all such patients should be followed radiologically for evidence of posterior extension. When the chiasm is threatened, surgical excision via a craniotomy approach is warranted to prevent subsequent hypothalamic or third ventricle involvement. Malignant optic glioma is a distinct disease primarily affecting middle-aged adults. The chiasm is always involved, and although one eye may be spared initially, rapid progression to bilateral blindness is usual. The disease is uniformly fatal.

Abstract
This Phase III trial tested the efficacy and safety of intra-arterial 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) for the treatment of newly resected malignant glioma, comparing intra-arterial BCNU and intravenous BCNU (200 mg/sq m every 8 weeks), each regimen without or with intravenous 5-fluorouracil (1 gm/sq m three times daily given 2 weeks after BCNU). All patients also received radiation therapy. A total of 505 patients were randomly assigned within the study. Fifty-seven patients were excluded, primarily because of neuropathology error, and the remaining 448 patients constituted the Valid Study Group. Of the total 505 patients, 190 patients could not receive intra-arterial BCNU and 315 patients were randomly assigned to receive intra-arterial (167 patients) and intravenous (148 patients) BCNU. Actuarial analysis (log-rank) demonstrated reduced survival for the intra-arterial group (p = 0.03). Serious toxicity was observed in the intra-arterial group; 16 patients (9.5%) developed irreversible encephalopathy with computerized tomography evidence of cerebral edema, and 26 patients (15.5%) developed visual loss ipsilateral to the infused carotid artery. Administration of 5-fluorouracil did not influence survival. The survival rate between the intravenous and the intra-arterial BCNU patients with glioblastoma multiforme did not differ, but was worse for intra-arterial BCNU patients with anaplastic astrocytoma than for those receiving intravenous BCNU (p = 0.002). Neuropathologically, intra-arterial BCNU produced white matter necrosis. It is concluded that intra-arterial BCNU is neither safe nor effective in prolonging survival when administered by the methods used in this study of newly diagnosed patients with malignant glioma.

Abstract
The authors entered 43 patients with recurrent malignant glioma in a trial of alternating sequential intracarotid BCNU and cisplatin. Protocol design was alternating courses of BCNU (2 doses, 300 to 400 mg each) and cisplatin (2 doses, 150 to 200 mg each) each at 4-week to 6-week intervals. Eight of 40 patients (20%) evaluable after the first course of BCNU showed partial or minor response. Only 18 patients were evaluable after the first course of cisplatin, and 5 were evaluable after the second course of BCNU. Median survival was 9 months (range, 2 weeks to 6 years). Cerebral or ocular toxicity unique to this method of chemotherapy administration and failure to show clinical improvement were the most common reasons for removal from study. Because of the high attrition rate, the authors were unable to determine a meaningful response to alternating sequential BCNU and cisplatin or to test the clinical degree of cross-resistance to these agents in human malignant glioma.

Abstract
A 28-year-old woman with a left frontoparietal anaplastic astrocytoma was treated postoperatively with a combination of cisplatin and 1-(4-amino-2-methylpyrimidine-5-yl) methyl-3-(2-chloroethyl)-3-nitrosourea hydrochloride (ACNU). The drugs were infused via the left supraophthalmic internal carotid artery in an attempt to avoid ocular toxicity. The patient subsequently developed blindness in the left eye and a right temporal hemianopsia from marked degeneration of the left optic nerve and tract. It is apparent that the placement of a catheter into the supraophthalmic carotid artery does not exclude visual complications.

Abstract
We determined the reliability of high-resolution contact B-scan echography for estimating the optic cup size in 56 eyes of 28 patients with glaucoma or ocular hypertension. Two trained observers independently evaluated horizontal and vertical cup/disk ratios in stereophotographs, and two skilled echographers independently estimated optic cup size in photoechograms in a masked fashion. The reliability of echographic interpretation varied (kappa 0.29 to 0.71), but it always exceeded that expected by chance alone, even for cups of 0.3 disk diameter or less. Subtly saucer-shaped cups (three of 50 eyes) and deep cups with intact neuroretinal rims (two of 50 eyes) were misinterpreted echographically. High-resolution contact B-scan echography may provide a useful and reliable estimate of the optic cup size in eyes with opaque media.

Abstract
We describe the neuropathologic findings at autopsy in six patients who developed a progressive encephalopathy complicating the treatment of malignant gliomas with combined intra-arterial 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) and cerebral irradiation. Four brains were free of tumor and one contained a microscopic focus of residual glioma. In only one case was there evidence of tumor progression. A disseminated process characterized by miliary foci of necrosis with mineralizing axonopathy was present in all cases, restricted to the internal carotid distribution of the perfused hemisphere and involving primarily though not exclusively the white matter, which was diffusely and severely edematous. This was combined in 3 cases with a histologically dissimilar, massive necrotizing leukoencephalopathy indistinguishable from pure radionecrosis. Much of the toxicity of this therapy is mediated by vascular injury, but the disseminated necrotizing lesion probably reflects, at least in part, direct neural damage.

Abstract
Forty patients with recurrent gliomas were treated with monthly intra-arterial infusions of cisplatin. Of the 35 evaluable patients, 12 (34%) responded with computerized tomography (CT) evidence of a decrease in tumor size; in 14 (40%) the tumor stabilized on CT scans, and in nine (26%) the disease progressed. The median survival period was 35.0 weeks for the responders and 27.5 weeks for all 35 patients. The primary toxicities were renal (reversible alterations in creatinine clearance), otological (severe hearing loss in one patient), and likely neurotoxicity in one patient who had received bilateral infusions following contralateral tumor progression. The authors are now using this form of regional chemotherapy sequentially before and following radiotherapy in newly diagnosed cases.

Abstract
Central neurotoxicity is reported in 5 of 16 patients with recently diagnosed anaplastic gliomas, who received intra-arterial BCNU (200 mg/M2/course) and also 2 in a series of 26 patients with recurrent gliomas similarly treated. Neurotoxicity was usually delayed, commencing several weeks following the second or third course. CT scans during central neurotoxicity represented 1 or more of 3 patterns: no change; increased low density area(s); and/or ipsilateral gyral enhancement and punctate calcification in the middle cerebral artery territory. In one clinicopathological correlation, coagulative necrosis of the white matter was observed, identical histologically to those changes recognized as delayed vascular events following radiotherapy. Cautious exploration of the various clinical factors that may contribute to this toxicity seems appropriate, as exploration of the potential benefits of regional chemotherapeutic infusions is undertaken.

Abstract
A therapeutic regimen is described for sedative, analgesic, and anti-emetic effect in patients receiving intra-arterial carmustine (BCNU) for malignant gliomas. This regimen consists of nalbuphine, 30 mg, i.v., and droperidol, 2.5 mg, i.v., given immediately prior to intra-carotid BCNU infusion. Droperidol, 2.5 mg, i.v., is then administered on four hour intervals for sixteen hours post-procedure. This combination provided excellent effect in nine patients treated for twelve intra-carotid infusions. None of the nine patients experienced vomiting, one experienced mild nausea several hours post-infusion, and non complained of severe pain or discomfort. Thirteen additional patients received diazepam, 10 mg, P.O., prior to the intra-carotid BCNU infusion, with fentanyl, 100 mcg, i.v., and prochlorperazine, 10 mg, i.m. at the onset of infusion. All thirteen patients suffered from severe nausea, vomiting, and orbital pain. The nalbuphine/droperidol combination is thought to provide a superior alternative to the traditional narcotic/pheonothiazine/benzodiazepine combination for carotid BCNU infusion. This combination has theoretical advantages for the patient with intracranial mass lesions by providing analgesia and sedation with minimal potential for respiratory depression and carbon dioxide retention.

Abstract
Arterial infusion of select chemotherapeutic agents has been shown to deliver increased drug concentration to brain tumors with reduced systemic toxicity. In this study, nine patients with histologically confirmed malignant glioma received cisplatin 110 mg and BCNU 300 mg fixed dose. All patients had received standard doses of cranial radiation after their initial surgical procedures. In three patients, intraoperative modification of the cerebral circulation was accomplished prior to the actual infusion because the vascular supply of the tumor arose from major arteries other than a single internal carotid artery. Supraophthalmic catheterization technique was employed. No neurological deficits occurred post infusion. The radiographic response rate was 25%. No responses were seen in patients who received less than 69 mg/M2 cisplatin this combination. The longest survival is 11+ months in a patient with anaplastic astrocytoma. Our first thirteen patients received cisplatin 150-200 mg and BCNU 300 mg for each infusion with a response rate of 83% in evaluable patients. Since modest reduction in cisplatin dose dramatically reduced the response rate, future studies should be directed at fine tuning the dose of this drug, or at neutralizing recirculating drug after its high dose first pass through the arterial circulation.

Abstract
Administration of BCNU into the carotid artery as treatment for malignant astrocytomas has produced retinal and brain toxicity. It is unclear whether the BCNU diluent, ethanol, is the cause of the toxicity, but the elimination of the ethanol is an attractive possibility. Clinically, decreasing the ethanol from 2.0 ml/100 mg BCNU to 0.75 ml/100 mg BCNU resulted in a marked decrease in eye toxicity. To simulate this clinical situation, three 500-mg solutions of BCNU, ethanol, and saline were prepared, decreasing the ethanol concentration from 3.0 ml to 2.0 ml to 0.75 ml/100 mg BCNU. The amount of BCNU recovered in vitro after simulated clinical administration of the three solutions decreased from 84.9% to 38.3% as the diluent decreased. Therefore, drug delivery at a fixed BCNU dose will decrease with the amount of ethanol diluent used. The clinical decrease in eye toxicity must be partly attributed to a decrease in the amount of BCNU delivered to the retina. Simulated administration of a solution of 500 mg BCNU/150 ml of 5% dextrose in water (D5W) gave 83.7% BCNU recovery. The D5W gives solubility comparable to that provided by 3.0 ml ethanol to each 100 mg BCNU, and its use eliminates ethanol as a potential retinal and brain toxin.

Abstract
A clinical analysis of 200 patients (307 eyes with optic disc drusen, 40 eyes with pseudopapilloedema without verified drusen, 53 normal fellow-eyes) was performed to document the characteristic findings in pseudopapilloedema with and without verified drusen. In 4 eyes optic disc drusen accounted for diminished visual acuity. Papillary or peripapillary haemorrhages were found in 6.1% of 347 eyes. Peripapillary pigment epithelial derangement was present in 29.7% of the eyes, mostly with superficial drusen. Subjective symptoms caused by drusen were very rare. Changes in the appearance of the optic discs with drusen during the years could be documented in 15% of 153 patients. There were 5 patients with pigmentary retinopathy. The most usual of coincident disorders was migraine in 21 patients. The visual field findings are analysed in a companion report.

Abstract
The ocular complications of intracarotid infusion of drugs for brain-tumor chemotherapy may be eliminated by infusion of the chemotherapeutic agent into the carotid artery above the origin of the ophthalmic artery. The authors have developed a catheter that can negotiate the carotid siphon. This catheter is not balloon-tipped but incorporates a flexible tip with an expanded end to facilitate drag by flowing blood. The exit hole is placed to allow remote manipulation of the tip by hydraulic forces. Using this catheter, the authors have been consistently able to infuse the supraophthalmic carotid artery.
