Postoperative vision loss following non ocular surgery- A case report

Introduction: Visual field loss is often the first sign of lesion of the anterior or posterior visual pathways. Screening for visual field defects should be a part of all routine eye examinations, mainly when neurological lesions are suspected. A confrontation visual field (CVF) test provide a rapid and practical method of visual field assessment, allowing the recognition of major neurological deficits. Materials and Research Methods: To report a case of posterior cerebral artery (PCA) stroke early suspected by CVF test. Case-Report: A 77 year-old male presented to our emergency department with vision blurring complaints and a strange sensation of a vision loss on one side on the left eye (OS), for the previous 15 days. He explained that symptoms initiated after an episode of dizziness followed by lipothymia. He denied diplopia or headaches. Past history revealed hypertension and diabetes as cardiovascular risk factors. The best corrected visual acuity was 20/25 on right eye (OD) and 20/60 on OS and pupillary reflexes were normal. CVF test was performed and showed a decrease on left hemicampus of OS. The biomicroscopy was normal and the fundus examination showed optic nerve edema bilaterally, also documented by Optical Coherence Tomography. Considering the findings and the history, neuroimaging and a neurological observation were requested. Computerized axial tomography revealed a hypodense lesion in right occipital posterior region, with hematic density. He was hospitalized for proper treatment with the diagnosis of posterior cerebral artery ischemic stroke, with further hemorrhagic transformation. Discussion: In acute stroke, visual disorders may form all or part of the initial presentation. Homonymous visual field deficits are well-known almost universal characteristics of PCA ischemia, however, due to the absent of cognitive impairment or speech problems associated to many cases, the diagnosis can be challenging at early stages. Our case-report highlights the importance of using CVF test to an immediate inspection of the peripheral visual field, in order to detect acute major defects, including homonymous deficits, to understand if a further prompt neurological examination is mandatory.

Intrduction. Tacrolimus (fujimycin or FK506) is a potent immunosuppressive drug with growing usage. It is usually used in prevention of transplanted organ rejection. Its use is highly valuable, but like other immunosupressants, it has adverse effects. One of them is optic neuropathy. Case report. A 47-year-old white male patients who had received tacrolimus therapy for nine years, after kidney transplantation, developed a subacute, painless vision loss on both eyes. He was thoroughly examined on different possible optic neuropathies and other causes of vision loss. After exclusion of other possible causes, the diagnosis of toxic optic neuropathy was established. His therapy was converted to cyclosporine, by his nephrologist, but his vision had improved only slightly. Conclusion. Toxic optic neuropathies are presented in everyday ophthalmological practice, but they are underestimated. Diagnosis can be demanding, especially when it comes to drugs and substances whose possible toxic effect on the optic nerve is not widely known. Unlike other adverse effects of tacrolimus therapy on nervous system, optic neuropathy can causes great and permanent functional impairment.

Central vision loss, photopsia, floaters and macular edema in a highly myopic patient can easily be misrelated to high myopia complications. However, in atypical cases, detailed examination along with a thorough diagnostic is required to establish the right diagnosis, which is often beyond the limits of the condition originally considered.

Intraocular Metastasis

Purpose: To describe the clinical and histopathological findings of a case of intraocular metastasis due to colorectal adenocarcinoma and to carry out a literature review. Case Report: A 64-year-old man with a history of tumor resection due to infiltrating colorectal adenocarcinoma three years previously sought ophthalmological care because of severe ocular pain without response to medical treatment and progressive vision loss in the left eye. On ultrasonographic examination, there was a heterogeneous intraocular choroidal tumor, which occupied approximately 40% of the vitreous cavity, as well as peritumoral serous retinal detachment. The patient underwent left eyeball enucleation. The histopathological diagnosis was metastatic tubular adenocarcinoma involving the retina and choroid that partially infiltrated the sclera and the proximal optic nerve. Conclusion: The present case highlights a rare pathological entity associated with variable therapeutic schemes and survival times and poor prognosis in patients with metastatic intraocular tumors due to colorectal adenocarcinoma.

Abstract Background and Importance We present a case of a patient with a residual intraosseous sphenoid wing meningioma presenting with proptosis, orbital pain, and monocular vision loss for 8 months who underwent decompression of the optic canal, orbital contents, and orbital reconstruction resulting in significant improvement in her vision loss with full resolution of proptosis and orbital pain. Clinical Presentation A 43-year-old female presented with a 1 year history of headache, peri-orbital pain, proptosis, and severe vision loss. She had previously undergone subtotal resection of a large Simpson Grade 1 spheno-orbital meningioma 3 years prior at an outside institution. Workup at our institution revealed hyperostosis of the left greater wing of the sphenoid bone and narrowing of the optic canal along with bony enhancement concerning for residual tumor. The patient was given the recommendation from outside institutions for radiation, presumably due to the chronicity of her visual loss. Our institution recommended resection of the residual osseous tumor with orbital reconstruction. Less than 2 weeks after surgery, the patient noted significant improvement in orbital pain and vision. At 3 months, she had regained full and symmetric orbital appearance with no orbital pain. Her visual acuity improved to 20/30 with full visual fields. Conclusion Surgical decompression of the optic canal and orbital contents for tumor related sphenoid wing hyperostosis should be strongly considered, despite an extended duration of visual change and loss. This case report shows that vision can be significantly restored even after symptoms have been present for greater than 6 months.
