Clinical profile and challenges faced in the management of optic neuritis: the Indian scenario.

PURPOSE: Optic neuritis (ON) is a relatively common ophthalmic disease that has recently received renewed attention owing to immunological breakthroughs. We studied the profile of patients with ON with special reference to antibody-mediated ON and the challenges faced in its management. METHODS: Case records of patients with ON presenting to a tertiary eye-care center in South India were analyzed. Data on demographics, presenting visual acuity (VA), clinical features, seropositivity for aquaporin-4 immunoglobulin G (AQP4-IgG) and myelin oligodendrocyte glycoprotein immunoglobulin G (MOG-IgG), details of magnetic resonance imaging (MRI) of orbits and brain, and treatment were collected. RESULTS: Among 138 cases with acute ON, male: female ratio was 1:2. Isolated ON was present in 41.3% of cases. Antibody testing of sera was performed in 68 patients only due to financial limitations. Among these, 48.5% were MOG-IgG-seropositive, 11.76% were AQP4-IgG-seropositive, and 30.88% samples were double seronegative. Other causes included multiple sclerosis (n = 4), lactational ON (n = 4), tuberculosis (n = 2), invasive perineuritis (n = 2), COVID-19 vaccination (n = 2), and COVID-19 (n = 1). The mean presenting best corrected visual acuity (BCVA) was 1.31 ± 1.16 logMAR (logarithm of the minimum angle of resolution). The mean BCVA at 3 months was 0.167 ± 0.46 logMAR. Only initial VA ≤ 'Counting fingers' (CF) had a significant association with the visual outcome for final VA worse than CF. The steep cost of investigations and treatment posed challenges for many patients in the management of ON. CONCLUSION: MOG-IgG-associated ON is common in India. Unfortunately, financial constraints delay the diagnosis and timely management of ON, adversely affecting the outcome.

Isolated Right Internal Jugular Vein Thrombosis: a Rare Complication of Acute Pancreatitis - a Case Report.

Vascular complications particularly splanchnic vein thrombosis can occur in acute as well as chronic pancreatitis, but extra-splanchnic thrombosis occurs rarely. We report a rare case of acute pancreatitis complicated by isolated internal jugular vein thrombosis. A 26-year-old Indian woman presented with complaints of severe epigastric pain radiating to the back, vomiting, and abdominal distension. Investigations showed low hemoglobin and serum calcium, and a raised serum amylase and lipase. Contrast-enhanced computerized tomography (CECT) of the abdomen suggested acute pancreatitis with bilateral pleural effusion and mild ascites. The patient was managed for acute pancreatitis with antibiotics, analgesics, pantoprazole, and other supportive treatment. She subsequently developed pain and swelling on the right side of the neck. Ultrasound Doppler examination of the neck revealed an isolated thrombus in the right internal jugular vein (IJV). The patient was started on enoxaparin and transitioned to warfarin. The patient improved symptomatically and was discharged on warfarin. A follow-up ultrasound Doppler examination showed a partial resolution of the clot. The patient was maintained on oral anticoagulants for 6 months. Isolated IJV thrombosis may complicate acute pancreatitis. A timely diagnosis and prompt treatment are critical for a positive outcome.

Clinical spectrum and functional outcome of firearm pellet-related eye injuries: A prospective follow-up study.

PURPOSE: To determine the prognostic significance of various clinical features and surgical techniques concerning anatomical and visual outcomes in shotgun pellet-inflicted ocular trauma. METHODS: This prospective follow-up study was done at a tertiary care institute in Kashmir, India. Six hundred sixty-four eyes of 643 patients with firearm pellet-related ocular trauma were followed up for 6 months. RESULTS: Ocular injury involved one eye in 622 (96.7%) patients and both eyes in 21 (3.3%) patients. Open globe injury (OGI) occurred in 451 (67.9%) eyes with perforating injury being the commonest type (248 eyes, 54.9%). For perforating injuries, entry wounds in the cornea and limbus had the worst prognosis. Closed globe injury (CGI) occurred in 213 (32.1%) eyes. An anatomical success rate of 66.3% (n = 250) was achieved for 56.8% (377/664) eyes requiring an average of 2.8 (SD 0.5) surgeries per eye. OGI was associated with poor outcomes in 259 (57.4%) and CGI with good outcomes in 200 (93.9%) eyes. The visual outcome had a significant association with grade and zone of injury both in OGI and CGI, and with the type of injury in OGI (p < .0001 each). Ocular trauma score (OTS) had a significant association with the degree of vision impairment (p < .0001). WHO category 0 visual impairment was seen in 270 (40.7%) eyes, category 1 in 85 (12.8%), category 2 in 35 (5.3%), category 3 in 30 (4.5%), category 4 in 172 (25.9%), and category 5 in 72 (10.8%) eyes irrespective of type of injury at 6 months post-treatment. CONCLUSIONS: The perforating injury was the commonest type of injury caused by shotgun pellets. The site of the entry wound in perforating injury had prognostic significance. The outcome was generally poor in OGI and good in CGI.

Spontaneous spinal intradural hemorrhage in dengue fever: a case report.

BACKGROUND: Spontaneous spinal cord hemorrhage is extremely rare in dengue fever. We report a case of spontaneous spinal intradural hemorrhage in dengue fever associated with severe thrombocytopenia. CASE PRESENTATION: A 48-year-old Indian woman presented with fever and body aches followed by acute onset of paraplegia with bladder and bowel dysfunction and loss of sensations below the level of the umbilicus. She had severe thrombocytopenia and positive dengue serology. Magnetic resonance imaging of the spine showed compression of the spinal cord due to intradural hematoma at the D7-D8 vertebral level. The patient received symptomatic treatment for dengue fever and steroids. Emergency D7-D8 laminectomy with excision of the clot and dural repair was done after stabilizing the platelet count with multiple platelet transfusions. The constitutional symptoms responded well to the treatment. There was good improvement in sensory symptoms but negligible improvement in paraplegia with a change in muscle power from grade 0/5 to grade 1/5 in the postoperative period. The patient was discharged from the hospital in a stable condition, but paraplegia showed little improvement during follow-up of 1 year. CONCLUSIONS: Spontaneous spinal cord hemorrhage can present as acute paraplegia in dengue fever. Failure to recognize this complication can delay initiating appropriate treatment with permanent loss of neurologic function.

Profile of sight-threatening diabetic retinopathy and its awareness among patients with diabetes mellitus attending a tertiary care center in Kashmir, India.

PURPOSE: To study the profile of sight-threatening diabetic retinopathy (STDR), its association with various factors affecting it, and awareness of diabetic retinopathy (DR) among patients with diabetes mellitus (DM) attending a tertiary care center in Kashmir. METHODS: In this prospective cross-sectional study, 625 consecutive patients with DM were assessed for STDR. Demographic/clinical data were obtained. Early treatment diabetic retinopathy study (ETDRS) criteria were used to grade fundus photographs. Severe nonproliferative DR, proliferative DR, and/or macular edema were classified as STDR. Optical coherence tomography was used to confirm the diagnosis of macular edema. RESULTS: The mean age of patients was 56.36 ± 9.29 years. The male-to-female ratio was 0.92:1. The majority (99.36%) of patients had type 2 DM. STDR was seen in 208 (33.28%) patients. Non-sight-threatening diabetic retinopathy (NSTDR) was seen in 173 (27.68%) patients. Eye care was sought by 313 (50.08%) patients for the first time. STDR had a significant association with difficulty in accessing the health care facilities, duration of diabetes, uncontrolled diabetes, presence of other diabetes complications, use of insulin, and hypertension (P < 0.05 for all). Awareness that diabetes can affect eyes showed a significant association with age, gender, educational status, duration of diabetes, glycemic status, DR, and STDR (P < 0.001 for all). CONCLUSION: STDR is a common complication in diabetes and is duration- and glycemic control-dependent. Understanding the factors associated with STDR can help in making strategies for its prevention. Spreading awareness regarding STDR at the community level in the Kashmir valley is crucial in this regard.

Etiological spectrum of irreversible blindness in Kashmir in North India.

PURPOSE: To determine the etiological spectrum of irreversible blindness in Kashmir Valley in India. METHODS: Patients presenting to a tertiary care hospital in Kashmir, India, with unilateral or bilateral blindness from April 2019 to March 2020 were included in this cross-sectional study. Blindness was defined using the World Health Organization (WHO) criteria. All subjects had a complete ophthalmologic examination and information was gathered regarding their demographic profile, nature of ocular disorder whether primary or secondary and laterality, if the ocular involvement was unilateral. RESULTS: 248 patients were enrolled in the study. The mean age of the patients was 57.17 years. The male: female ratio was 2.17:1. The commonest cause of unilateral or bilateral blindness was glaucoma (22.58%) followed by diabetic retinopathy (DR) (17.74%). Unilateral blindness was seen in 78.62% of the patients. Unilateral blindness occurred mainly due to glaucoma (16.41%), DR (14.87%), age-related macular degeneration (13.33%), and trauma (pellet injury: 10.76%, non-pellet injury: 10.25%). The major causes of bilateral blindness were glaucoma (45.28%), DR (28.30%), and hereditary/congenital retinal diseases (16.98%). Socioeconomic status and educational status were significantly associated (P < 0.05 each) while age, gender, place of residence, and occupation were not significantly associated (P > 0.05 each) with the number of eyes affected by blindness. CONCLUSION: Glaucoma and DR are the foremost causes of irreversible blindness in Kashmir. Public health plans aimed at encouraging good health education of patients should be developed in this region. Moreover, patients should be screened effectively for glaucoma and diabetes at the level of primary health care facilities.
