Simeprevir (SMV), Paritaprevir (PTV) and Grazoprevir (GZR) were the common leads identified which show higher binding affinity to both nsp13 helicase and nsp14 as compared to the control inhibitors and therefore, they might be potential dual-target inhibitors. The leads also establish a network of hydrogen bonds and hydrophobic interactions with the key residues lining the active site pockets. The present findings suggest that these FDA approved antiviral drugs can be subjected to repurposing against SARS-CoV-2 infection after verifying the in silico results through in vitro and in vivo studies.
To report a case of conjunctival plaque infected from
, which was possible transmitted from a cat.

A case of Thai woman presented with chronic painless ulcerated conjunctiva with white plaque. The lesion was not healed for one month after excision. She became concerned of getting infection from her cat because it developed chronic and multiple skin lesions on its legs. Identification of
by PCR method was confirmed in the tissues from her conjunctiva and cat's skin.

The diagnosis of Sporothrix infection should be suspected in atypical conjunctival lesion in patient who had closed contact with infected cat. This brought awareness to doctors and cat owners, even though it was uncommon.

We report an unusual case of a thirty-three-year-old woman who presented with acute unilateral vision loss following pregnancy and was ultimately discovered to have a pilocytic astrocytoma of the optic nerve.

A thirty-three-year-old previously healthy female presented one month following Caesarean section with unilateral vision loss. She was found to have significantly decreased visual acuity, an afferent pupil deficit, proptosis, optic nerve edema and choroidal folds. Imaging revealed a large lesion of the optic nerve. Biopsy was performed and pathologic analysis revealed a pilocytic astrocytoma, WHO grade 1. The patient opted for close observation without further management and demonstrated mild improvement in visual function.

Optic pathway gliomas (OPG) most commonly present in the pediatric patient population with painless proptosis, slowly progressive vision loss, and clinical findings of chronic optic neuropathy.( Farazdaghi et al., 2019 Sep) 1 Acute presentations of this disease in adulthood are rare. This case demonstrates a rare case of acute optic nerve glioma presentation during the post-partum period.

Nuclear medicine imaging can provide a noninvasive means of distinguishing inflammatory mass lesions from oncologic intraocular tumors.

We report a case of paraneoplastic ocular sarcoidosis with choroidal mass lesions that was initially concerning for choroidal metastasis of a primary carcinoid tumor. PET CT was utilized with two different tracers to characterize the choroidal mass as being FDG-avid, consistent with a sarcoid-like lesion, and lacking the Gallium (Ga-68) DOTATAE uptake of carcinoid tumor metastases.

Functional imaging is valuable to distinguish clinically similar inflammatory verses oncologic intraocular pathology.

Sporotrichosis is the most common subcutaneous mycosis in the world and it is presented usually in the lymphocutaneous form. When the eye is involved, it typically includes the conjunctival and periorbital tissues or even the intraocular tissues.

We present a case of a 13-year-old girl complaining about nodules in the left malar region and in both the outer nasal corner and the lower eyelid of the left eye, which had appeared one month earlier.

and significance Sporotrichosis is a hyperendemic disease in Brazil and its diagnosis is based on clinical aspects, epidemiological history, and culture. Ophthalmologists and other professionals should be aware of this condition.

To describe the clinical course of a patient with refractory pseudophakic cystoid macular edema treated with interleukin-6 receptor antagonist tocilizumab.

An 80-year-old Caucasian man with past ocular history significant for glaucoma (right eye) and iritis presented with cystoid macular edema (CME) in the right eye (OD). His ocular surgery history was significant for cataract extraction with posterior chamber intraocular lenses in 1999 and YAG laser capsulotomy in 2014 in both eyes (OU). His medications at time of presentation included latanoprost and dorzolamide-timolol in OD for glaucoma, as well as prednisolone in OD for iritis. Upon examination, his visual acuity was 20/250 in OD and 20/20 in the left eye (OS). Intraocular pressure was 20mmHg in OD and 10mmHg in OS. Slit-lamp examination revealed no cells or flare in OU. Dilated fundus exam showed CME and a cup-to-disk ratio of 0.9 in OD and normal findings in OS. Initial spectral domain optical coherence tomography (SD-OCT) demonstrated intraretinalour with complete resolution of CME.

IL-6 inhibition with tocilizumab may be a safe and effective treatment for refractory CME. Further studies are needed to elucidate the nature and extent of therapeutic IL-6 inhibition in CME.

Optical coherence tomography (OCT) is established as a promising technology for assessing the optic nerve atrophy progression after trauma. However, reports on the effectiveness and sensitivity of ganglion cell layer (GCL) and Bruch's membrane opening-minimum rim width (BMO-MRW) for studying this damage course over time are still lacking.

A 53-year-old man with severe optic nerve trauma had repeated OCT scans of the retinal nerve fiber layer (RNFL), GCL and BMO-MRW during 12 months after the injury. There was gradual damage in all measurements. Interestingly, BMO-MRW was the first analysis affected whilst GCL showed the greatest damage over time.

Our outcomes suggest that OCT might be able to assess axonal loss after traumatic optic neuropathy. https://www.selleckchem.com/products/SB939.html BMO-MRW measurement might be more sensitive than other analyses in the first two weeks after trauma and GCL might better monitor belated damage. Thus, it might be possible to combine all these sets of measurements to increase diagnostic sensitivity an specificity.

We describe a patient with secondary open-angle glaucoma and serous macular detachment associated with pulmonary hypertension.

A 59 year-old male with pulmonary hypertension presented with vision loss and was noted to have bilateral engorged epibulbar vessels, blood in Schlemm's canal, elevated intraocular pressure, retinal venous tortuosity and serous retinal detachments. Enhanced depth optical coherence tomography (ED-OCT) showed bilateral serous macular detachments with marked choroidal thickening. Fluorescein angiography and indocyanine green angiography revealed choroidal vascular congestion and engorgement. Improvement of subretinal fluid was achieved with systemic control of his venous hypertension, and the intraocular pressure responded to medical anti-glaucoma therapy.

Pulmonary hypertension may be associated with secondary open-angle glaucoma, choroidal engorgement and serous macular detachment, and should be considered in the differential diagnosis of elevated episcleral venous pressure. Management of ocular complications is challenging and requires a multi-disciplinary approach.

To report use of ultrasound biomicroscopy (UBM) and anterior segment ocular coherence tomography (AS-OCT) in a case of pseudophakic glaucoma in a patient with an anterior chamber intraocular lens.

UBM and AS-OCT were critical in determining a non-drug related etiology of angle closure. Images indicated anterior obstruction of the pupil secondary to anterior chamber intraocular lens, but also posterior obstruction of the pupil secondary to the anterior hyaloid face.

When evaluating a patient with suspected angle closure, it is important to perform a full ophthalmologic examination, including gonioscopy, as well as a thorough review of past medical history and medications so as not to miss systemic-related etiologies. Imaging with B-scan, UBM, and, more recently in the last decade, AS-OCT is a key component of evaluation of a patient in angle closure, especially one with a complex medical and ocular history.

Presentation of a rare lesion a case of upper eyelid lipoma.

A 76-year-old otherwise healthy woman presented with a right upper eyelid swelling. Her medical history was recorded. On ophthalmologic examination a soft, non-ulcerated and not well-circumscribed mass was evident. An ultrasonography examination was carried out showing a hyperechoic non capsulated mass situated between the superior orbital margin and the orbicularis oculi muscle.

Eyelid lipomas must be differentiated from herniated orbital fat, cystic lesions, tumours, and the lacrimal gland.A pre-operative differential diagnosis of eyelid lipoma can be done through medical history, ophthalmologic, and ultrasonography examinations. Nevertheless, in case of doubt a magnetic resonance imaging (MRI) should be performed to assess a possible orbital involvement and to plan for the right surgical procedure to be performed.
