Systemic toxicity of topical corticosteroids

Corticosteroids are known to cause many ocular and systemic side effects when administered by oral or parenteral routes. Corticosteroid induced systemic toxicity secondary to topical steroid eye drops is rare. A 6-week-old, male infant was brought to our tertiary eye care center with bilateral congenital cataracts. The child underwent phacoaspiration with primary posterior capsulotomy without intraocular lens implantation in both eyes at an interval of 6 weeks. Child was initiated on topical betamethsone 0.1% eight times a day, tobramycin 0.3% six times a day, homatropine 2% twice a day, and carboxymethylcellulose 0.5% four times a day. Two and four weeks later he underwent surgical membranectomy in the right and left eye respectively followed by frequent use of topical steroids, initially given 1 hourly and then tapered weekly in the follow-up period. The patient showed increase in intraocular pressure and gain in body weight along with development of cushingoid habitus nearly 6 to 8 weeks after starting topical steroids. These side effects started weaning off following the reduction in dose of topical steroids, suggesting the role of the corticosteroid-related systemic side effects. This case highlights the serious systemic side effects secondary to increased frequency and duration of topical corticosteroid use in infancy. Hence, dosage of topical steroids should be adjusted in its therapeutic range to prevent their ocular and systemic side effects. Therefore, close monitoring is advocated for children using topical corticosteroids to prevent serious ocular and systemic side effects.

Long-term outcomes of cataract surgery in children with uveitis

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.

Safety and efficacy of dexamethasone implant along with phacoemulsification and intraocular lens implantation in children with juvenile idiopathic arthritis associated uveitis

Purpose: To assess the safety and efficacy of intraoperative intravitreal dexamethasone implant in patients of juvenile idiopathic arthritis (JIA)-associated uveitis undergoing phacoemulsification with posterior chamber intraocular lens (PCIOL) implantation. Methods: Retrospectively, data of patients with JIA-associated uveitis undergoing phacoemulsification with PCIOL implantation with intraoperative dexamethasone implant injection were analyzed. Patients with a minimum follow-up of 6 months were included. Primary outcome measures were ocular inflammation, intraocular pressure (IOP), best-corrected visual acuity (BCVA), and worsening of uveitis. Results: 8 eyes of 6 patients were included. BCVA was significantly improved at 1, 3, and 6 months postoperatively 0.20 ± 0.09, P = 0.008; 0.18 ± 0.11, P = 0.008; and 0.24 ± 0.11, P = 0.01, respectively. No statistical difference noted in mean IOP at various follow-up visits. None developed worsening of uveitis or Cystoid macular edema. Conclusion: Intraoperative intravitreal dexamethasone implant is a safe and effective in preventing and managing the postoperative inflammation in children with JIA-associated uveitic cataract.

Ocular chemical burns from accidental exposure to topical dermatological medicinal agent

We report a case of accidental ocular chemical injury by self-medication with a single application of a topical ayurvedic medication containing salicylic acid, phenol, and tincture iodine, which is being used in developing countries for treatment of various dermatological conditions.
