Clinical profile of anterior uveitis in tertiary health centre of central India

To study the clinical profile of anterior uveitis in patients attending the Ophthalmology department of tertiary health centre of central India A cross-sectional, observational study was done in the department of Ophthalmology of tertiary health centre from January 2017 to July 2019. A total of 199 cases of anterior uveitis were studied to assess their clinical presentation and etiology. After thorough history taking, demographic data and clinical pattern were documented. Comprehensive ophthalmic evaluation, necessary laboratory investigations and radiological imaging were performed to establish the etiology. The maximum number (n=79; 39.7%) of patients were in the age group of 21-40 years and the mean age of the study subjects was 36.9+21.8 years. The male to female ratio was 1:1.42 (117 females, 82 males). Uniocular disease was found in 91.95% cases and majority (n=175; 87.93%) of the patients had acute presentation with 95.47% cases having non granulomatous uveitis. A specific diagnosis could not be made in 62.8% cases. Trauma (21.7%) was the most common cause in patients with a specific diagnosis. Persistent posterior synechiae was the most frequently seen complication (21.08%) although majority of the patients (66.8%) did not reveal any major complications.Patients with anterior uveitis most commonly had acute presentation. The disease was rarely bilateral and was mostly non-granulomatous in presentation. It was mostly idiopathic and among the known etiological factors, trauma was the most common cause.

The Prevalence of MRI-Defined Sacroiliitis and Classification of Spondyloarthritis in Patients with Acute Anterior Uveitis: A Longitudinal Single-Centre Cohort Study

Background: Acute anterior uveitis (AAU) is a relatively common extra-musculoskeletal manifestation of axial spondyloarthritis (axSpA); however, data on the prevalence of active sacroiliitis in patients with AAU are limited. Methods: 102 patients with AAU and 39 healthy subjects (HS) underwent clinical assessment and sacroiliac joint MRI. Patients with absence of active sacroiliitis were reassessed after two years. International Spondyloarthritis Society (ASAS) classification criteria for axSpA (regardless of patient’s age) and expert opinion for definitive diagnosis of axSpA were applied. Results: Although chronic back pain was equally present in both groups, bone marrow edema (BME) in SIJ and BME highly suggestive of axSpA was found in 52 (51%) and in 33 (32%) patients with AAU compared with 11 (28%) and none in HS, respectively. Out of all AAU patients, 41 (40%) patients fulfilled the ASAS classification criteria for axSpA, and 29 (28%) patients were considered highly suggestive of axSpA based on clinical features. Two out of the 55 sacroiliitis-negative patients developed active sacroiliitis at the two-year follow-up. Conclusions: One-third of patients with AAU had active inflammation on SIJ MRI and clinical diagnosis of axSpA. Therefore, patients with AAU, especially those with chronic back pain, should be referred to a rheumatologist, and the examination should be repeated if a new feature of SpA appears.

Epidemiology and Clinical Features of Anterior Uveitis: a Prospective Study

Purpose: To report the pattern, epidemiology, and clinical features of anterior uveitis (AU) in southern TaiwanMethods: A prospective case series was performed to recruit patients with AU at two medical centers (Kaohsiung Chang Gung Memorial Hospital and Kaohsiung Veterans General Hospital) in southern Taiwan from December 1, 2018 to March 31, 2020. These patients enrolled were reviewed for clinical diagnoses, ocular presentations, and laboratory data, including aqueous polymerase chain reaction tests.Results: A total of 112 patients were included. The most common clinical diagnoses were idiopathic AU (37.5%), HLA-B27-associated acute AU (25.0%), and herpetic AU (18.8%); among herpetic etiology, cytomegalovirus (CMV) was the most common pathogen. Hypertensive AU was associated with older age, more males, and greater numbers of corneal edema, and fewer iris posterior synechiae. Compared with HLA-B27-associated acute AU, CMV AU was associated with older age, high intraocular pressure, more keratic precipitates, greater iris atrophy, more pseudophakia, and fewer pupil posterior synechiae. Conclusion: This prospective study identified the epidemiological and clinical features of AU in southern Taiwan. The most common etiologies were idiopathic AU, HLA-B27-associated acute AU, and herpetic (most CMV) AU.

Lens and Anterior Uvea

This chapter illustrates photos of clinical signs seen in uveitis and interesting cases of lens pathologies. Anterior uveitis is the inflammation of the iris and the ciliary body. Anterior uveitis can be idiopathic, isolated, or associated with systemic diseases. The clinical findings observed in anterior uveitis include keratic precipitates, inflammatory cells and flare in anterior chamber, hypopyon, rarely hyphema, miosis, iris nodules and atrophy, synechiae, and band keratopathy in chronic cases (shown in corneal degenerations chapter). The inflammation in anterior uveitis is almost always immune. Treatment includes steroid eye drops, cycloplegic drops, sub-Tenon steroid injections when cystoid macular edema is present. Chronic macular edema can be treated with intravitreal Triamcinolone injection and Dexamethasone implants. In cases of refractory anterior uveitis or associated immune systemic diseases, immunomodulatory treatment or biologic agents are prescribed.

Ocular findings in cats with blastomycosis: 19 cases (1978–2019)

OBJECTIVE To document ocular findings in cats with blastomycosis. ANIMALS 35 cats with blastomycosis. PROCEDURES Medical records from 1978 through 2019 were reviewed to identify cats with confirmed Blastomyces infection. Cats were grouped as having or not having ocular involvement. Clinical signs, histopathologic findings, and response to treatment were evaluated. RESULTS 21 of the 35 (60%) cats with confirmed blastomycosis had ocular abnormalities. Two of 21 cats with ocular abnormalities also had systemic hypertension and were excluded. Of the remaining 19 cats, 15 (79%) had bilateral ocular signs. Ten (53%) cats had inflammatory ocular lesions, and 9 (47%) had neuro-ophthalmic abnormalities. Six of the 19 (32%) cats appeared to be completely blind, and 5 (26%) appeared to be unilaterally blind. For the 10 cats with inflammatory ocular lesions, the most common lesions were anterior uveitis (9/20 eyes), active chorioretinitis (6/20 eyes), and retinal detachment (4/20 eyes). For the 9 cats with neuro-ophthalmic abnormalities, the most common abnormalities were a negative menace or tracking response (10/18 eyes) and negative pupillary light response (4/18 eyes). CLINICAL RELEVANCE Results suggested that ocular involvement is common in cats with blastomycosis and that both inflammatory lesions and neuro-ophthalmic abnormalities can be seen. Blastomycosis should be considered in the differential diagnosis for cats with anterior uveitis, posterior segment inflammation, or neuro-ophthalmic abnormalities, and a complete ophthalmic examination should be performed in all cats with confirmed or suspected blastomycosis.

Ocular manifestation and visual outcomes in herpes zoster ophthalmicus: a prospective study from a tertiary hospital of Eastern India

AIM: To estimate the magnitude of different ocular manifestation in clinically established herpes zoster ophthalmicus (HZO) patients and assessment of the visual outcome after two months of initial examination. METHODS: An observational prospective study was conducted on 42 clinically diagnosed Tzanck smear positive cases HZO to observe the occurrence and frequency of different ocular manifestation and their visual outcome in 10-month period with 2mo follow up. Full ophthalmological examination using slit lamp, non-contact tonometry, applanation tonometry, direct and indirect ophthalmoscope were performed. RESULTS: Out of 42 patients of HZO, 33 had one or more type of ocular manifestation staring from lid skin involvement to conjunctivitis, keratitis, uveitis, increased intraocular pressure (IOP) and optic neuritis but no retinal manifestation. More number of HZO cases and ocular manifestation were found with advancement of ages. Young HZO patients were more associated with human immunodeficiency virus (HIV) infection and HIV infected people with HZO infection had more ocular manifestation. Male to female ratio was 2:1 among HZO cases but ocular manifestation occurred more among males. Female with advanced age were involved more. Lid involvement (73.81%), conjunctivitis (69.05%), and keratitis (59.52%) were most common ocular manifestation followed by anterior uveitis (30.95%) and episcleritis (11.90%). Ocular hypertension (42.86%) was associated with almost every ocular manifestation. Among the cases of more than 45 years of age, 9.52% patients acquired 6/6 vision compared to 7.14% patients at and below 45 years of age after 8wk of follow up. CONCLUSION: The visual outcomes are poor in HZO with advanced age group. Visual outcome of the affected eyes is poor than unaffected eyes. The loss of vision is mainly due to keratitis, anterior uveitis, posterior uveitis, and optic neuritis.
