Purpose:To investigate outcomes for different treatment modalities in congenital nasolacrimal duct obstruction (CNLDO) in an Indian population.Design:Retrospective, interventional, case series.Materials and Methods:In an institutional setting, case records of patients with CNLDO from January 2008 to 2012, were reviewed, and data on patient demographics, clinical presentation, and treatment details (sac massage, probing, and/or dacryocystorhinostomy) were recorded. Success of treatment was defined as complete resolution of symptoms and negative regurgitation on pressure over lacrimal sac (ROPLAS) area.Results:Two hundred and ninety-eight eyes of 240 patients with a mean age of 22.2 ± 26.14 months (median = 12 months, interquartile range = 17) were analyzed. Sac massage (n = 226) was successful in 67 eyes (30%). Multivariable logistic regression analyses showed that children with mucoid ROPLAS were almost 6 times more likely (odds ratio [OR] = 5.55 vs. clear ROPLAS, 95% confidence interval [CI] = 2.35–13.09, P < 0.001) to experience failure of sac massage. Overall probing (n = 193) was successful for 143 (74%) eyes. Multivariable logistic regression showed that older children were 25% more likely to experience probing failure (OR = 1.25 for every 6 months increment in age, 95%, CI = 1.09–1.42, P = 0.001).Conclusion:Sac massage is successful in only a third of our patients and those with mucoid ROPLAS are more likely to experience failure. Probing is successful in three-quarter of our subjects, and its success declines with a progressive increase in age. Lower socioeconomic status, poor general health, and recurrent respiratory infections are unique to our population and may influence outcomes.

The purpose of the study is to report an unusual case of encapsulated iron intraocular foreign body (IOFB) of long duration presenting with cystoid macular edema (CME) and normal full-field electroretinogram (ERG). A 28-year-old male presented with a history of metal injury 5 years back and subsequent visual loss in the left eye for 3 months. Fundus examination of the left eye showed an encapsulated cyst-like structure inferior to the disc with the surrounding pigmentary changes and CME. B-scan ultrasonography and computed tomography scan confirmed metallic IOFB. A full-field ERG performed before surgery showed a normal response. He underwent pars plana vitrectomy with IOFB extraction and silicone oil injection as a tamponade. Two months later, silicone oil removal was combined with intravitreal triamcinolone acetonide (IVTA) injection for persistent edema. Meticulous clinical evaluation, imaging, electrophysiological testing coupled with surgical intervention, and IVTA injection resulted in resolution of CME with minimal visual improvement. In conclusion long-standing encapsulated iron IOFB on the retina can cause vision-threatening complications without siderosis.
