Purpose:
To evaluate the long-term outcomes of cataract surgery in children with uveitis.
Methods:
Retrospective, noncomparative review of medical records of children (≤16 years) with uveitic cataract who had undergone cataract surgery between January 2001 and December 2014 at a tertiary care center was done. The main outcome measures were visual acuity and postoperative complications.
Results:
We recruited 37 children (58 eyes) who were diagnosed with uveitic cataract and underwent cataract surgery. The etiology of uveitis included juvenile idiopathic arthritis (
n
= 19), presumed intraocular tuberculosis (
n
= 8), idiopathic (
n
= 4), Behçet's disease (
n
= 2), Vogt–Koyanagi–Harada syndrome (
n
= 2), human leukocyte antigen B-27 associated uveitis (
n
= 1), and toxocariasis (
n
= 1). Phacoemulsification with intraocular lens (IOL) implantation was performed in 17 patients (27 eyes; 46.55%), while 20 patients (31 eyes; 53.44%) were left aphakic after pars plan lensectomy and vitrectomy. At an average follow-up of 3.69 ± 7.2 (SD) years, all cases had significant improvement in corrected distance visual acuity post cataract extraction; visual acuity of 20/40 or more was achieved in 32 eyes (55.17%). The most common complication was capsular opacification (37.93%). Incidence of secondary procedures as well as glaucoma was not statistically different in patients undergoing IOL implantation from those who were aphakic.
Conclusion:
Even though number of secondary procedures was more in pseudophakic group, meticulous choice of surgical technique and adequate immunosuppression lead to a modest gain of visual acuity in children undergoing IOL implantation in uveitis. However, scrupulous case selection and aggressive control of pre- and postoperative intraocular inflammation are the key factors in the postoperative success of these patients.
BackgroundWe report unfavorable outcome in a patient with subretinal granuloma caused by dual infection of Mycobacterium tuberculosis complex with Mycobacterium fortuitum and Mycobacterium bovis in an immunosuppressed, non-HIV patient. We did a systematic review of literature on dual infection due to M. tuberculosis and M. fortuitum via MEDLINE and PUBMED and could not find any case reported of causing this kind of dual infection in the eye.ResultsA 38-year-old Indian male patient presented with decreased vision in the left eye for 3 months, diagnosed as tubercular choroidal granuloma with associated retinal angiomatosis proliferans (RAP) lesion. He also had multiple enlarged lymph nodes in the chest, and sternal pus sample was positive for acid-fast bacilli (AFB). M. tuberculosis complex was detected by gene expert. The patient was started on antitubercular treatment (ATT) whereby the lung lesions improved but the ocular lesion showed initial clinical improvement followed by worsening. Twenty-five-gauge diagnostic pars plana core vitreous surgery was done whereby sample demonstrated a large number of AFB on Ziehl-Neelsen stain and auramine-rhodamine stain. The vitreous sample showed growth on routinely inoculated mycobacteria growth indicator tube (MGIT) 960 tubes, and multiplex polymerase chain reaction (PCR), Gene Xpert MTB/ RIF assay (Cepheid, Sunnyvale, CA), and line probe assay (LPA) were positive for ocular tuberculosis. In view of nonresponse to conventional ATT, a suspicion of dual infection of M. tuberculosis complex with a nontubercular mycobacteria was kept and a subculture was made onto the solid Lowenstein-Jensen (LJ) medium from the positive MGIT 960 tubes. Two morphologically distinct types of colonies were obtained on LJ slopes. Subsequently, the two etiological agents were identified as M. fortuitum and M. bovis by PCR from the vitreous sample.ConclusionsCo-infection of M. tuberculosis complex with nontubercular mycobacterium (NTM) has never been reported from ocular tuberculosis before. In immunosuppressed individuals, who test positive for MTB, not responding to the standard ATT, one needs to have a high index of clinical suspicion to rule out associated NTM infection and initiate appropriate multidrug systemic antibiotic therapy early.
The significantly higher supine IOP is frequently missed in routine glaucoma practice. An early morning supine IOP measurement may reveal a peak IOP hitherto not picked up during routine office IOP measurements, and may be a useful measurement in unexplained progressive glaucoma.
While anterior uveitis is the commonest uveitis in children, our cohort reported a high number of posterior uveitis cases compared to previous studies. Tuberculosis and JIA were the commonest causes of pediatric uveitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
