    Abstract Purpose: To evaluate the clinical profile of myopic strabismus fixus (MSF) in children and surgical outcomes of silicone band loop myopexy.
    Method: We retrospectively reviewed records of children presenting with MSF who underwent silicone band loop myopexy between January 2008 and December 2020 at a tertiary eye care center. Data concerning demographics, refractive error, axial length, extra-ocular motility, and ocular alignment pre-operatively and post-operatively, intra- and post-operative complications, ocular and systemic associations, were evaluated. The long-term effects of band loop myopexy on ocular alignment stability, motility improvement, and myopia progression were analyzed. Surgical outcome was defined as post-operative orthotropia or heterotropia less than or equal to 20 PD.
    Results: A total of0 eyes of 7 patients (median age: 5 years; 5 boys and 2 girls) who underwent band loop myopexy were included in the study. Among them, three children underwent bilateral and four children underwent unilateral band loop myopexy. Medial rectus recession was performed only in two patients as a part of initial procedure. The median follow-up duration was 7 years. Most of the children, i.e. six of them presented with esotropia-hypotropia and only one patient presented with exotropia-hypotropia complex. The median pre-operative measurements were esotropia of 62.5 PD, hypotropia of5 PD, and exotropia of4 PD. Postoperative average primary position deviation measured was close to 9-10 PD of esotropia. The overall motility improved to -1 from -3.
    Conclusion: The clinical profile of MSF in children is almost similar to adults. This condition is a rare entity among adults as well as children. Majority of children with MSF presented with esotropia-hypotropia complex. Silicone band loop myopexy with or without medial rectus recession proves to be a reliable surgical procedure as it provides stable outcomes in terms of ocular alignment and motility among children.

    Abstract A man in his 80s, with a history of diabetes, hypertension and coronary artery disease, presented with bilateral painless progressive vision loss 2 years prior. His examination showed subnormal best corrected visual acuity of 20/50 and 20/80 in the right eye and left eye (LE), respectively, grade II relative afferent pupillary defect in LE, normal anterior segment, intra-ocular pressure (IOP) and defective colour vision in both eyes (BE). Fundus examination revealed optic disc pallor, disc collaterals and grade 2 hypertensive retinopathy in BE. Automated perimetry showed advanced field loss in BE. MRI of the brain and orbits with contrast showed signs of raised intracranial pressure, and magnetic resonance angiogram of the brain showed multiple arterio-venous channels along with the right transverse and sigmoid sinuses. The patient was referred to a neuroradiologist for further evaluation, and cerebral angiogram confirmed multifocal high-flow dural arterio-venous fistulae at right jugular foramen, transverse and sigmoid sinuses. He underwent Onyx liquid embolization.

    Abstract We report clinical and optical coherence tomography (OCT) differences among patients with occult neuroretinitis and non-arteritic anterior ischaemic optic neuropathy (NAAION). We retrospectively reviewed records of patients with a final diagnosis of occult neuroretinitis and NAAION seen at our institute. Data were collected regarding patient demographics, clinical features, concomitant systemic risk factors, visual function, and optical coherence tomography (OCT) findings at presentation and subsequent follow-up. Fourteen and 16 patients were diagnosed to have occult neuroretinitis and NAAION, respectively. Patients with NAAION were slightly older (median age 49, inter-quartile range [IQR]: 45-54 years, versus 41, IQR: 31-50 years) than patients with neuroretinitis. Seventy-five per cent of patients with NAAION were male versus 43% with neuroretinitis (

    Abstract Pediatric optic neuritis (PON) is one of the commonest causes of acute vision loss in children. Although it might often be postinfectious or postvaccination, recent understanding and available evidence suggest that it can be the first manifestation of a neuro-inflammatory syndrome such as multiple sclerosis, neuromyelitis optica spectrum disorder, acute disseminated encephalomyelitis or myelin oligodendrocyte glycoprotein associated optic neuritis. Therefore, neuroimaging, serological testing, cerebrospinal fluid analysis, testing for various systemic autoimmune conditions become a part of the workup. However, this can be exhaustive and expensive, especially in countries with limited access to health insurance. Many recent studies suggest that neuroimaging and few clinical features can provide clues to the underlying etiology. However, serological tests can provide a confirmatory evidence. Therefore, in this mini-review, we propose a balanced approach to the evaluation of PON, based on the available literature emanating in the last decade.

    Abstract A preschool girl presented with sudden-onset bilateral painless loss of vision from 2 days prior. Child's examination showed light perception vision, sluggishly reacting pupils, otherwise normal anterior segment, healthy optic disc and retina in both eyes. MRI of brain and orbit with contrast revealed thickened left part of the optic chiasm with contrast enhancement extending proximally to bilateral optic tract and hyperintensities in the left thalamus and periventricular white mater. Considering the topographical distribution of lesions in the brain, neuromyelitis optica spectrum disorder was suspected. The child was started on intravenous methylprednisolone followed by tapering oral steroids. Serological testing was positive for myelin oligodendrocyte glycoprotein (MOG) and negative for aquaporin-4 antibodies. This case represents an unusual case of MOG associated demyelination disorder where the distribution of lesions showed chiasmal involvement along with optic tract, thalamus and deep white mater lesions.
