We present a case in which Gilbert syndrome was diagnosed following a neuro-ophthalmic complaint. Adverse effects of drugs as well as various systemic, neurological, and local ocular pathologies can cause accommodative insufficiency and loss of accommodation. A 29-year-old man was admitted to an ophthalmology department with blurred vision and diagnosed as suffering from acute accommodation paralysis. He had a history of being given a pheniramine maleate injection for pruritus 20 days previously. Symptoms began immediately following the injection. After systemic evaluation and laboratory tests, he was diagnosed as having Gilbert syndrome. His complaints and symptoms recovered in approximately a further 10 days. Metabolism of pheniramine maleate can be impaired in Gilbert syndrome and anticholinergic effects can cause accommodation paralysis.

A 6-year-old boy with a complaint of blurred vision for two months was referred to our clinic. His visual acuity was 20/32 in the right eye and 20/20 in the left eye. Optical coherence tomography (OCT) revealed optic disc pit maculopathy in the right eye. The patient was followed for 6 months without any treatment. At the end of the 6-month period, the patient's visual acuity was 20/20 in both eyes. The OCT imaging showed spontaneous regression of the optic disc pit maculopathy. In this case report, it is concluded that in children, spontaneous regression of the optic pit maculopathy with full recovery of visual acuity is possible. The development of optic pit maculopathy in childhood is rare and there are not enough studies on the treatment methods. Therefore, our case report may be helpful in the management of similar cases of pediatric optic disc maculopathy.

A 61-year-old male suffered from sudden blurred vision and superior visual field defect oculus dexter. His vision was counting fingers at 20 cm. Fundoscopy demonstrated inferior pale retina and a large embolus located at the proximal inferior retinal artery. Branch retinal artery occlusion (BRAO) was diagnosed. Initial paracentesis, topical brimonidine tartrate, oral pentoxifylline, and hyperbaric oxygen therapy were performed but showed limited improvement. Hence, he received 25-gauge vitrectomy, artificial posterior vitreous detachment, blocked retinal artery massage, and bloodletting 5 days after onset. After the surgery, his vision improved to 20/25. Fundoscopy showed reperfused retina, and optical coherence tomography revealed resolved retinal edema. RAO is an ophthalmological emergency; however, no standard guideline is available. Vitrectomy with blocked retinal artery massage and bloodletting showed favorable results in this case of BRAO with a large embolus. More prospective clinical trials are needed for setting up the standard treatment.

BACKGROUND Non-islet cell tumor hypoglycemia (NICTH) is a newly recognized, but uncommon, paraneoplastic syndrome that is associated with tumors of mesenchymal origin. We report a case of NICTH associated with a gastrointestinal stromal tumor (GIST). CASE REPORT A 60-year-old man presented to the emergency department of our hospital after being found unconscious in his home. His serum blood glucose on hospital admission was 40 mg/dL. He reported a three-month history of diffuse abdominal pain, fatigue, and blurred vision. Laboratory medicine investigations showed reduced levels of insulin, C-peptide, insulin-like growth factor binding protein (IGFBP)-3, and insulin-like growth factor (IGF)-1, but his IGFBP-2 was increased. Computed tomography (CT) scan of the chest and abdomen showed an abdominal mass that involved the small bowel, mesentery, and omentum, with lesions in the right lung and the left rib. Histopathology of a CT-guided biopsy of the abdominal mass showed a low-grade sarcomatous spindle cell neoplasm that was positive for CD117 using immunohistochemistry and with an exon 11 c-KIT mutation. These findings were consistent with a diagnosis of GIST and treatment with imatinib commenced. CONCLUSIONS This case report has shown that hypoglycemia in the setting of low levels of insulin, C-peptide, IGF-1, and IGFBP-3 is suggestive of a diagnosis of NICTH, which should be investigated for an underlying source, which in this case, was confirmed to be a malignant GIST.

Varicella zoster virus-associated neuroretinitis is rare. We report a patient who presented with blurred vision of the left eye and extraocular movement pain. A fundoscopic examination revealed disc edema, hyperemia, and macular edema. The impression was neuroretinitis. Intravenous methylprednisolone pulse therapy was administered. However, visual recovery was incomplete with optical coherence tomography (OCT) imaging showing photoreceptor layer disruption. The laboratory data were rechecked and demonstrated a high varicella zoster virus immunoglobulin G titer. Varicella zoster virus-associated neuroretinitis was suspected and oral acyclovir was prescribed. His visual acuity improved to 0.9 after 2 weeks of treatment, and OCT showed photoreceptor layer restoration. Spectrum-domain OCT provides useful information when evaluating the disease course of neuroretinitis.

The case is reported of a patient with pulmonary and ocular tuberculosis presenting with blurred vision in both eyes. A 27-year-old well-nourished male nursing-home resident with a previous history of traumatic intracerebral hemorrhage was brought to the ophthalmological clinic due to progressively blurred vision. His best-corrected visual acuity was 20/400 in the right eye with only light perception in the left eye. Fundus examinations revealed retinal segmental periphlebitis and hemorrhagic retinitis in the right eye and dense vitreous hemorrhage in the left eye. The Mantoux test was negative; however, the results of an interferon gamma release assay were positive. Ocular tuberculosis was suspected. Although he had never had any respiratory symptoms, his chest radiograph and computed tomography scan showed a multiple centrilobular glandular and ground-glass appearance with air-space consoli dations and atelectasis in both lower lobes. Pulmonary tuberculosis was confirmed by a positive acid-fast stain of a bronchial alveolar lavage sample. A GEN-PROBE amplified Mycobacterium tuberculosis direct test of the vitreous fluids was also positive. Ocular tuberculosis was confirmed. After treatment for tuberculosis and vitrectomies, his final best-corrected visual acuity improved to 20/30 in the right eye and 20/200 in the left eye. Ocular tuberculosis is rarely reported as the primary presentation of systemic tuberculosis in young patients. A negative Mantoux test may lead to misdiagnosis and delayed treatment. Doctors should become more familiar with the manifestations of systemic tuberculosis and use advanced diagnostic tools in cases of clinical suspicion.

Uveal metastasis is the most common intraocular malignancy. Lung cancer is one of the most common malignancies that metastasize to uvea. Iris involvement is rarely reported. Here we report a case of iris metastasis from pulmonary adenocarcinoma that was treated with photodynamic therapy (PDT). A 65-year-old Chinese man was referred to our hospital for iris white neoplasm and blurred vision for 2 weeks in his right eye. His accepted pulmonary lobectomy, radiotherapy and chemotherapy for pulmonary adenocarcinoma 1year ago and liver metastases were found 2 months earlier. At presentation, anterior segment examination of the right eye showed a hypopigmented, vascularized papillary 3.8 *3.19mm neoplasm located on the temporal iris expanding to 9-clock anterior chamber angle. The patient refused to accept MRI, biopsy and treatment. One week later the tumor grew up to 5.5*7.4mm with diffuse mixed conjunctiva congestion and elevated IOP. A modified PDT was applied. Intravenous verteporfin (3mg/m2) was infused with a 1min bolus. PDT with 3 partly overlapped 5mm laser spots, 689nm (50J/cm2) and 166s were performed 4 minuets later without contact lens. The neo-genesis vessels were occluded with small patch bleeding on the edema tumor that was separated from the anterior chamber angle in the 3days follow-up. PDT may be a safe, noninvasive and psychologically well-accepted treatment for iris metastasis.

A 61-year-old man was admitted to our hospital because of decreased visual acuity. On admission, he had marked blepharoedema, conjunctival injection, exophthalmos, diplopia, and blurred vision. He also had bronchial asthma and urinary retention requiring urethral catheterization. His serum immunoglobulin (Ig) G4 level was elevated to 1,830 U/mL. Fluorodeoxyglucose-positron emission tomography revealed an abnormal uptake in multiple organs. A histopathological examination of the salivary gland revealed IgG4-positive plasma cell infiltration, leading to a diagnosis of IgG4-related ophthalmic disease. After initiating steroid therapy, his longstanding ophthalmic, respiratory, and urinary symptoms dramatically improved. In IgG4-related disease, steroid therapy should be considered even if patients have longstanding symptoms.

The number of new psychoactive substances (NPS), synthetic cannabinoids (SCs) in particular, is growing constantly. Because of the insufficiently explored effects on consumer health, they have become a major problem in the emergency departments. They are difficult to identify, and there are no antidotes that could reverse their detrimental effects. We report a case of poisoning of a young man who used SCs. The patient was admitted to the emergency department of the Clinical Hospital Merkur, Zagreb (Croatia) after sniffing and smoking a herbal product bought on the street. He presented with severe cognitive difficulties and visible eye redness. Other symptoms included somnolence, disorientation, loss of coordination, unsteady gait, hyporeflexia, stiffness, cramps and cold limbs, blurred vision, teeth grinding, dry mouth, tinnitus, fear, suicidal thoughts, impaired focus, memory, and speech, sedation, fatigue, depression, thought blocking, and autistic behaviour. His skin was dry, and his mucosa dry and irritated. Herbal products "Rainbow Special" and "Luminated Aroma" used by the patient were qualitatively analysed with gas chromatography / mass spectrometry (GC/MS) after direct extraction with an organic solvent. Solid-phase extraction method was used to analyse serum and urine samples. Despite the negative findings of biological samples, mostly due to the limitations of GC/MS, the clinical picture infallibly pointed to the poisoning with SCs. This was confirmed by the findings of 5-fluoro AMB (methyl 2-(1-(5-fluoropentyl)-1H-indazole-3-carboxamido)-3-methylbutanoate) in the herbal products.

A 79-year-old man who had been diagnosed with small cell lung carcinoma (SCLC) complained of right ocular pain and blurred vision. His right intraocular pressure (IOP) was 30 mm Hg, and anterior chamber cells and multiple grayish white iris masses associated with peripheral anterior synechia (PAS) and neovascularization of the right iris were observed. We presumed that the iris masses were iris metastasis of SCLC. Despite therapy with topical eye drops and oral acetazolamide, the IOP was poorly controlled, so we injected intravitreal bevacizumab into his right eye for neovascular glaucoma. Neovascular glaucoma disappeared rapidly, but the IOP did not improve because of total PAS. To our knowledge, there is only one report of the use of intravitreal bevacizumab for SCLC metastasis in that eye and they reported that intravitreal injection resulted in successful short-term regression of presumed iris metastasis and improved control of secondary neovascular glaucoma, and the case had over one-half PAS. The previous report and our results suggest that secondary neovascular glaucoma with iris metastasis may be controlled by early intravitreal bevacizumab injection.
