Résumé
Purpose: To describe the demographics and epidemiology of uveitis presenting to a multi?tier ophthalmology hospital network in Southern India. Methods: Cross?sectional hospital?based study of 19,352 patients with uveitis presenting between March 2012 and August 2018. Results: In total, 1,734,272 new patients were seen across the secondary and tertiary centers of our multi?tier ophthalmology hospital network during the study period. Among them, 25,353 eyes of 19,352 patients were diagnosed with uveitis and were included in the study. Uveitis constituted 1.11% of all cases. The majority of patients were male (60.33%) and had unilateral (68.09%) affliction. The most common age group was 21� years with 12,204 (63.06%) patients. The most common type of uveitis was anterior uveitis, which was seen in 7380 (38.14%) patients, followed by posterior uveitis in 5397 (23.89%) patients. Among the infectious causes, tuberculosis was the most common etiology (2551 patients, 13%) followed by toxoplasmosis (1147 patients, 6%). Conclusion: Uveitis constituted 1.11% of all cases presenting to our clinics. It was more common in the age group of 21� and was predominantly unilateral. Anterior uveitis was the most common subtype seen in 38%.

Purpose: The purpose was to study choroidal thickness and its profile based on location in healthy Indian children using enhanced depth spectral‑domain‑optical coherence tomography (SD‑OCT). Methods: In this cross‑sectional observational study 255 eyes of 136 children with no retinal or choroidal disease were consecutively scanned using enhanced depth SD‑OCT. Eyes with any ocular disease or axial length (AXL) >25 mm or < 20 mm were excluded. A single observer measured choroidal thickness from the posterior edge of the retinal pigment epithelium to the choroid/sclera junction at 500‑microns intervals up to 2500 microns temporal and nasal to the fovea. Generalized estimating equations were used to evaluate the correlation between choroidal thickness at various locations and age, AXL, gender and spherical equivalent (SEq). Results: Mean age of the subjects was 11.9 ± 3.4 years (range: 5–18 years). There were 62 Females and 74 males. The mean AXL was 23.55 ± 0.74 mm. Mean subfoveal choroidal thickness was 312.1 ± 45.40 μm. Choroid was found to be thickest subfoveally, then temporally. Age, AXL and SEq showed a significant correlation with choroidal thickness, whereas gender did not affect choroidal thickness. Conclusion: Our study provides a valid normative database of choroidal thickness in healthy Indian children. This database could be useful for further studies evaluating choroidal changes in various chorioretinal disorders. Age and AXL are critical factors, which negatively correlated with choroidal thickness.
Résumé
hypertension, dyslipidemia, carotid artery disease, etc., In this report, we describe four patients with isolated abducens nerve palsy who presented with an acute onset diplopia whose detailed history and examination were suggestive of an ischemic etiology. Detailed systemic and laboratory evaluation revealed hyperhomocysteinemia as the only potential risk factor. To the best of our knowledge this is the first report of association of hyperhomocysteinemia and isolated abducens nerve palsy.

A case of bilateral acute retinal necrosis due to herpes simplex virus 1, in a child is reported. The case presented as an extensive hemorrhagic retinopathy that was misdiagnosed as non-infective initially. Diagnostic aqueous tap of the blind eye for viral DNA by polymerase chain reaction helped to confirm viral etiology when the other eye was affected. Appropriate antiviral therapy followed by prompt surgeries for subsequent retinal detachment helped to salvage useful vision in the second eye.

Vitreous hemorrhage is one of the most common differential diagnoses for sudden painless decrease in vision. Often, it is caused by retinal vascular disorders secondary to common systemic ailments such as diabetes mellitus, systemic hypertension and haematological abnormalities. Sometimes it may be the beginning of a retinal tear and consequent retinal detachment that can be vision threatening if not operated early. This paper lays out practical guidelines for a tailored approach needed to arrive at the aetiology of vitreous haemorrhage so that appropriate, timely treatment can be planned.
