Purpose: To report the incidence of, and to estimate the long-term risk and predisposing factors and the surgical outcomes for, retinal detachment (RD) after pediatric cataract surgery. Design: Retrospective consecutive interventional case series. Participants: During the study period 1996 to 2007 at a tertiary eye care institute, 481 eyes of 295 children aged below 16 years with no other ocular and systemic anomalies who underwent lensectomy, posterior capsulorrhexis, and anterior vitrectomy combined with primary intraocular lens implantation were included. The median follow-up was 66 months. Methods: Kaplan-Meier estimates and Cox proportional hazard regression model were used for estimating cumulative risk and hazard ratio (HR), respectively. Difference between measured preoperative axial length and age-matched mean axial length (prior studies) was calculated, and was defined as age-adjusted axial length difference (ALD) (minus and plus denotes myopia and hypermetropia, respectively). Main Outcome Measures: Cumulative risk and potential risk factors for RD. Results: Of the total, 12 eyes of 9 children developed RD after cataract surgery, with a median time of 70 months. The overall risk of RD was 5.5% at 10 years after cataract surgery. All 9 children were male. The multi-adjusted HR associated with increased risk of RD was 12.42 (95% confidence interval [CI], 2.91-53.01; P = 0.001) for eyes of children with intellectual disability and 21.93 (95% CI, 2.95-162.80; P = 0.003) for eyes of children with age-adjusted ALD < -1 mm (myopic). Retinal break associated with induction of posterior vitreous detachment was the most common (8 eyes) cause of RD. No surgical intervention was done in 2 eyes. Scleral buckle and vitrectomy combined with belt buckle were performed in 4 and 6 eyes, respectively. At final follow-up, 5 and 9 eyes had a visual acuity better than or equal to 6/18 and 6/60, respectively. Conclusions: A 5.5% risk for RD is estimated for the first 10 years after cataract surgery in children with no known ocular and systemic anomalies. The risk significantly increases in a male, myopic, and intellectual disabled child. We emphasize the need for regular and long-term follow-up after pediatric cataract surgery. © 2017 American Academy of Ophthalmology.

Eales' disease is an idiopathic inflammatory venous occlusive disease. It primarily affects young adults and is often bilateral. It is characterized by three overlapping stages of venous inflammation (vasculitis), occlusion, and retinal neovascularization. Diagnosis is mostly clinical and requires exclusion of other systemic or ocular conditions that could present with similar retinal features. Recurrent vitreous haemorrhage is the hall mark of Eales disease. Treatment is usually corticosteroids in the inflammation stage and photocoagulation in the proliferative stage of the disease. Visual prognosis is good if treated early in the course of the disease. © 2010 Macmillan Publishers Limited All rights reserved.

Telemedicine is exchange of medical data by electronic telecommunications technology that allows a patient's medical problems evaluated and monitored by a remotely located physician. Over the years, telemedicine and telescreening have become important components in health care, in both disease detection and treatment. Highly visual and image intensive ophthalmology is uniquely suited for telemedicine. Because of rising disease burden coupled with high opportunity cost in detection, diabetic retinopathy is an ideal ophthalmic disease for telescreening and decision-making. It fits to Wilson and Jungner's all 10 criteria of screening for chronic diseases and the American Telehealth Association's 4 screening categories.

Because of their varied spectrum of clinical presentation and difficulty in management, pediatric uveitis remains a challenge to the ophthalmologist. Variations in clinical presentation, difficulties in eye examination, extended burden of the inflammation over quality of life, limited treatment modalities, risk of amblyopia are the main challenges in the management of pediatric uveitis. Pediatric uveitis is a cause of significant ocular morbidity and severe vision loss is found in 25-33% of such cases. This article summarizes the common causes of uveitis in children with special approach to the evaluation and diagnosis of each clinical entity. Copyright: © 2013 Khandekar RB.

PURPOSE. To report a case of pulmonary edema, in a child under general anesthesia, due to iatrogenic acute hypertensive crisis following instillation of 1 drop of 5% phenylephrine eyedrops. METHODS. A 2-year-old boy was scheduled for examination of both eyes and enucleation of the left eye under general anesthesia. In the preoperative ward, 1 drop of 2.5% phenylephrine eyedrops was instilled 3 times by the nursing staff. The child was induced with the volatile agent Sevoflurane and intubated with Inj atracurium besylate 0.5 mg/kg IV. Anesthesia was maintained with N2O/oxygen (2:1)/Sevoflurane 1.5% and Inj fentanyl 1 μg/kg IV. As the pupil was not dilated optimally for examination, 1 drop of 5% phenylephrine eyedrops was instilled. Approximately 10 minutes following its instillation, tachycardia and rise in blood pressure occurred. Auscultation of the chest revealed bilateral coarse crepitations and pink frothy secretions were noted in the Portex endotracheal tube. RESULTS. Pulmonary edema was effectively settled using positive pressure ventilation with 100% oxygen, Inj lasix 1 mg/kg IV, and Inj hydrocortisone 100 mg IV. The concentration of inhalational agent, Sevoflurane, was increased. Within about 15 minutes, both heart rate and blood pressure gradually returned to normal limits. Following surgery, the child was extubated, fully awake. CONCLUSIONS. To produce maximum mydriasis, with minimum systemic effects, preventive strategies such as using the lowest drug concentration, punctual occlusion, eyelid closure, allowing adequate time for the pharmacologic effect to occur, and the use of microdrops in infants should be adopted. © 2010 Wichtig Editore.

AIM:: To evaluate the short-term outcomes of lensectomy, combined with vitrectomy, scleral-fixated intraocular lens (SFIOL), and trabeculectomy with adjunctive mitomycin C (MMC) in patients with subluxated/dislocated crystalline lenses with associated elevated intraocular pressure (IOP). MATERIALS AND METHODS:: This retrospective case series included 51 eyes of 51 patients who underwent lensectomy, vitrectomy, and SFIOL combined with trabeculectomy with MMC between 2003 and 2012. The main outcome measures assessed were IOP, change in visual acuity, IOP-lowering medications, and the complications and reoperation rates. RESULTS:: The most common etiology observed was blunt trauma in 35 eyes (68.6%). Glaucomatous optic neuropathy was detected in 13 eyes (25.49%) preoperatively. The IOP reduced significantly from a preoperative mean of 26.3±11.5 mm Hg to 13±4.6 mm Hg (P<0.001) at the final visit. The mean preoperative number of IOP-lowering medications of 2.9±0.8 reduced to 0.3±0.7 at last follow-up (P<0.001). The best-corrected visual acuity (Snellens) improved significantly from 20/600 to 20/60 (P<0.001). Complete success defined as IOP≤21 mm Hg without medications was achieved in 93%±5% and 80%±13% at 1 and 2 years, respectively. Major postoperative complications included retinal detachment in one eye and SFIOL dislocation in another. CONCLUSIONS:: The technique of combining SFIOLs with trabeculectomy with adjunctive MMC in the management of subluxated/dislocated lenses resulted in good IOP control and improvement in visual acuity.

Purpose: The aims of this study were to report the prevalence of various microvascular complications and to identify the various clinical and biochemical characteristics related to these complications in subjects with newly diagnosed type II diabetes. Methods: Of the 5999 subjects enumerated, 1414 subjects with diabetes (both known and newly diagnosed) were analyzed for the study. Among the diabetic subjects, 248 (17.5%) were newly diagnosed with diabetes and the remaining had history of diabetes. All subjects underwent a detailed standard evaluation to detect diabetic retinopathy (fundus photography), neuropathy (vibration pressure threshold), and nephropathy (microalbuminuria). Results: The prevalence of any form of microvascular complication was 30.2% (95% confidence interval [CI] = 24.5-35.9). The prevalence of diabetic retinopathy was 4.8%, and that of diabetic nephropathy and neuropathy was 10.5%. The risk factors for developing any form of microvascular complication were increasing age (odds ratio [OR] = 1.07, 95% CI = 1.04-1.11, P <.0001), increasing systolic blood pressure (OR = 1.03, 95% CI = 1.01-1.06, P =.001), and increasing hemoglobin (OR = 1.39, 95% CI = 1.09-1.79, P =.011). The risk factors for diabetic retinopathy and diabetic nephropathy were increasing systolic blood pressure (OR = 1.06 [P =.001] for retinopathy and OR = 1.04 [P =.012] for nephropathy) and increasing hemoglobin (OR = 2.20 [P =.007] for retinopathy and OR = 1.57 [P =.023] for nephropathy). The risk factor for diabetic neuropathy was increasing age (OR = 1.12, P <.0001). Conclusions: Nearly one third of the newly diagnosed type II diabetes subjects had some form of microvascular complication; nephropathy, and neuropathy being commoner than retinopathy. © 2012 Elsevier Inc.

Aims: To provide a fact file on the etiology, clinical presentations and management of retinal vasculitis in Eastern India. Materials and Methods: Retrospective, record based analysis of retinal vasculitis cases in a tertiary care center in Eastern India from January 2007 to December 2009. Results: One hundred and thirteen eyes of 70 patients of retinal vasculitis were included in this study. Sixty (85.7%) patients were male (mean age 33 11.1 years) and 10 (14.3%) were female (mean age 32.4 13.6 years). Vasculitis was bilateral in 43 (61.4%) and unilateral in 27 (38.6%) patients. Commonest symptoms were dimness of vision (73; 64.6%) and floaters (36; 31.9%). Vascular sheathing (82; 72.6%) and vitritis (51; 45.1%) were commonest signs. Mantoux test was positive in 21 (30%) patients but tuberculosis was confirmed in only four (5.71%) patients. Raised serum angiotensin-converting enzyme level and positive antinuclear antibody level were reported in four (5.71%) patients each. Human leukocyte antigen B5 (HLA B5) marker was present in one (1.4%) patient. However, none of the total 70 patients were found to have a conclusively proven systemic disease attributable as the cause of retinal vasculitis. Oral corticosteroid (60; 85.7%) was the mainstay of treatment. Forty-eight (42.5%) eyes maintained their initial visual acuity and 43 (38%) gained one or more line at mean follow-up of 16.6 6.3 months. Conclusion: Retinal vasculitis cases had similar clinical presentations and common treatment plan. There was no systemic disease association with vasculitis warranting a careful approach in prescribing investigations.
