Objective: To present a case with infliximab-induced retrobulbar optic neuritis.

Case description: A 58-year-old woman presented to our clinic with a two-day history of blurred vision in her right eye. She had numerous uveitis attacks previously, and she was on infliximab treatment for ankylosing spondylitis. Her best-corrected visual acuity was counting fingers and 20/25 in the right and left eye, respectively. Optic discs seemed healthy in fundoscopic examination. The right optic nerve showed high signal intensity on magnetic resonance imaging (MRI). Infliximab treatment was discontinued and systemic steroid therapy was started. After the treatment her best-corrected visual acuity improved to 20/20 in her right eye.

Conclusion: Infliximab is a chimeric human-murine monoclonal antibody used in autoimmune diseases. Optic neuritis is a rare but important side effect of infliximab. Thus, infliximab-induced optic neuritis should be kept in mind for patients receiving infliximab treatment.

Purpose: To present results of contemporary multimodal ophthalmic imaging in a case of maternally inherited diabetes and deafness (MIDD) and a literature review of MIDD.

Methods: A case of a 47-year-old female with diabetes mellitus, severe insulin resistance, familial lipodystrohy, deafness and increasing problems with vision is reported. A full ophthalmic examination was done, including best corrected visual acuity (BCVA, LogMAR), funduscopy, and imaging studies: optical coherence tomography (OCT), OCT angiography (OCT-A), fundus autofloresence (FAF), visual fields (HVF) 10-2 , electrophysiology (EP) and genetic testing were performed. Literature available on the topic was reviewed.

Results: BCVA was 0.06 LogMAR in the right eye and 0.1 LogMAR in the left. Funduscopy revealed atrophy (AT) and pigmentary changes but no diabetic retinopathy. HVF confirmed corresponding defects. The imaging and diagnostic tests showed the following abnormalities: FAF: hypoautofluoresence in areas of AT and mottled appearance in the macular and peripapillary area; OCT: attenuation of outer retinal layers and retinal pigment epithelium (RPE) in the AT; OCT-A: thinning of the deep capillary plexus and choriocapillaris; EP: abnormalities on full field electroretinogram (ERG), 30 Hz flicker and single cone flash response; multifocal ERG: reduced responses; genetic testing: A-to-G transition mutation at position 3243 of the mitochondrial genome, typical for MIDD. After one year OCT ganglion cell analysis showed loss of thickness.

Conclusions: Genetic testing should be considered in diabetic patients with pigmentary retinopathy. Imaging studies and diagnostic testing showed structural and functional retinal changes, confined to the macula and progressive in nature.

Background: A common carotid artery occlusion (CCAO) is very rare and the clinical features of CCAO have rarely been described. Since the blood supply of the eye and orbit is derived from the internal carotid artery, a CCAO may present with various ophthalmological symptoms, ranging from incidental findings to complete visual loss but also other neuro-ophthalmological abnormalities.

Case report: A 61-year-old woman presented with acute monocular vision loss and an elevation deficit of the right eye. Fluorescein angiography showed delayed filling of both the retinal and choroidal vasculature, without occlusion/embolisms of the retinal arteries. Vascular imaging showed a right CCAO.

Conclusion: CCAO has a variable presentation. In patients with acute unilateral visual loss a CCAO should be considered, especially when ocular motility deficits are present. Fluorescein angiography examination can aid in the localization and diagnosis of the vascular insult. Urgent referral for a systemic work-up is essential.

Purpose: To report a case of (neuro)sarcoidosis presenting solely with recurrent cranial nerve palsies in a 57-year-old Caucasian female.

Methods: Case report with clinical imaging.

Results: A 57-year-old female first presented with a right sixth nerve palsy, which resolved spontaneously after 6 months. Three years later she was diagnosed with a sixth nerve palsy in the fellow eye followed by a complete palsy of the left third cranial nerve four months after. Medical history consisted of migraine and hypercholesterolemia. Further neurological and ophthalmic work-up was unrevealing at first. After repeated magnetic resonance imaging, an enhancing lesion in the left cavernous sinus was seen, which was initially diagnosed as a meningioma. However, imaging of the chest revealed an image of sarcoidosis, and the lesion and ophthalmoplegia of the left eye disappeared with systemic corticosteroid treatment.

Discussion: Sarcoidosis is the ultimate imitator and the possibility of neurosarcoidosis must be taken into account when presented with unexplained ophthalmoplegia. Neurosarcoidosis has imaging properties very similar to other diseases such as a meningioma, and misdiagnosis occurs easily. Spontaneous recovery of ophthalmoplegia can rarely occur in neurosarcoidosis.

Objective: Toxic anterior segment (TASS) is a rare acute sterile anterior segment inflammation that typically develops within 12 to 24 hours after an anterior segment surgery. The purpose of this case report is to alert surgeons to the possibility of this complication following any anterior segment surgery, including trabeculectomy, and to highlight the possible etiologies and measures to prevent it.

Patient and method: A 58-year-old male glaucoma patient was initially managed medically for primary open angle glaucoma with antiglaucoma medications. There was rapidly progressive glaucomatous optic nerve damage in his left eye within the following year, despite the use of antiglaucoma medications, hence the need for trabeculectomy.

Result: The post-operative condition of the patient's eye was stormy with diffuse limbus-to-limbus corneal edema and profound Descemet's membrane folds, among other features of TASS, with associated deteriorating visual acuity.

Conclusion: Although there is no documented report of TASS following trabeculectomy with mitomycin C, surgeons should be alerted to this possibility. Preventive measures include extreme care to avoid errors while preparing and administering diluted solutions, especially medications that are administered into the intracameral space.

Ocular tuberculosis is a great mimicker of various uveitis entities. We present a case of a 29-year-old male who came in with blurring of vision and floaters in the left eye. On examination, the left eye had anterior chamber cells and vitritis associated with retinitis. He had no other symptoms. The initial presentation was consistent with ocular toxoplasmosis, and he was started on oral sulfamethoxazole-trimethoprim and showed a good response to the treatment. However, work-up revealed negative toxoplasma antibody titers but a positive M. tuberculosis interferon-gamma release assay test and Mantoux test, making the diagnosis of ocular tuberculosis more likely. The patient was shifted to antituberculous therapy, which eventually resulted in the resolution of the inflammation with a recovery of the visual acuity. The diagnosis of ocular tuberculosis requires a detailed medical history as well as microbiologic and immunologic studies. A high index of suspicion by the treating ophthalmologist is necessary to reveal the diagnosis.

Dolichoectatic arterial compression of the anterior visual pathway is a rare but recognized condition. The functional impact, however, is still less clear. We describe a case of a 56-year-old male with diminished visual acuity in the left eye and incongruent inferior visual defect in both eyes caused by dolichoectasia due to a congenital hypoplasia of one horizontal segment of the circle of Willis and subsequent arterial compression of the chiasm and left optic nerve.

Purpose: To report the case of an extremely large overhanging bleb, extending from superior fornix to limbus, in a 57-year-old poorly controlled diabetic, six years after trabeculectomy for an uncontrolled primary open angle glaucoma (POAG) with recurrence, months after complete excision.

Methods: An overhanging bleb is defined as a filtering cicatrix which has been massaged downward over the cornea by eyelid action. It has been linked to anti-metabolite use during glaucoma filtering surgery. Despite being functional, these blebs result in patient discomfort ranging from foreign body sensation and lacrimation to dysphotopsia. A 57-year-old male presented with complaints of reduced vision, foreign body sensation, watering, and difficulty in eye closure in the left eye (OS) for past 6 months. He had undergone trabeculectomy with mitomycin C 6 years ago for advanced primary open-angle glaucoma with no follow-up beyond the initial one 4 weeks post-surgery.

Results: At presentation, he had a giant multi-loculated, cystic filtering bleb (15 mm x 8 mm x 4-5 mm), which was carefully excised. Amniotic membrane was used as an anti-fibrotic as well to cover the defect. Seven months after surgery, there was recurrence of this overhanging cystic bleb when it was again excised with debulking of the conjunctiva done and cryotherapy applied to its margins.

Conclusion: Although multiloculated cystic overhanging blebs have been documented before, such a large (posterior extent till fornix), thick-walled multiloculated bleb with histopathological evidence of chronic inflammatory process has not been reported prior.

Central serous chorioretinopathy (CSCR) is a chorioretinal disease that is characterized by central vision loss and is usually seen in middle-aged males. It has been associated with the use of various drugs, including corticosteroids and phosphodiesterase inhibitors. We present the case of a 36-year-old male who developed CSCR after a few weeks of irregular use of quetiapine for his sleep problems. The clinical findings of the patient improved shortly after he stopped using the drug, and at the end of the two-month period complete recovery was observed. Quetiapine is an atypical antipsychotic that exerts its effects on dopamine and serotonin receptors. There are studies showing that these neurotransmitters may play a role in the control of choroidal vascular permeability, which is the underlying cause of CSCR. Therefore, we believe that quetiapine may have a causal relationship with CSCR. To our knowledge, this is the first case report documenting full recovery from quetiapine associated CSCR.
