V (May. 2017), PP 56-61 www.iosrjournals.org Congenital Cataract- Approach and Management Review Dr.Bhawesh Chandra Saha1, Dr.Rashmi Kumari2, Dr Bibhuti Prasanna Sinha3 1Senior Resident,AIIMS ,Patna 2Senior Resident,Regional Institute Of Ophthalmology,IGIMS ,Patna 3Professor,IGIMS,Patna All India Institute Of Medical Sciences ,Patna ,Indira Gandhi Institute Of Medical Sciences,Patna Abstract: Childhood cataract remains a challenge to pediatric ophthalmologists despite recent major breakthrough in surgical techniques and instrumentation. Pediatric cataract is one of the major causes of preventable childhood blindness, affecting approximately 200,000 children worldwide, with an estimated prevalence ranging from three to six per 10,000 live births Congenital cataracts usually are diagnosed at birth. If a cataract goes undetected in an infant, permanent visual loss may ensue. The management of pediatric cataract is a team effort of ophthalmologist ,pediatrician,anaesthetist and parents and should be customized depending upon the age of onset, laterality, morphology of the cataract, and other associated ocular and systemic co-morbidities.This review attempts to summarize the available management options to these patients along with some analytical recommendations to optimise the outcome. Keywords: Pediatric cataract,childhood blindness I. Introduction Pediatric cataract is one of the major causes of preventable childhood blindness, affecting approximately 200,000 children worldwide, with an estimated prevalence ranging from three to six per 10,000 live births1-3. It may be congenital, if present within the first year of life, developmental if present after infancy, or traumatic.

  • Pediatric Cataracts: a Retrospective Study of 12 Years (2004
    Pediatric Cataracts: A Retrospective Study of 12 Years (2004 - 2016) Cataratas em Idade Pediátrica: Estudo Retrospetivo de 12 ARTIGO ORIGINAL Anos (2004 - 2016) Jorge MOREIRA1, Isabel RIBEIRO1, Ágata MOTA1, Rita GONÇALVES1, Pedro COELHO1, Tiago MAIO1, Paula TENEDÓRIO1 Acta Med Port 2017 Mar;30(3):169-174 ▪ https://doi.org/10.20344/amp.8223 ABSTRACT Introduction: Cataracts are a major cause of preventable childhood blindness. Visual prognosis of these patients depends on a prompt therapeutic approach. Understanding pediatric cataracts epidemiology is of great importance for the implementation of programs of primary prevention and early diagnosis. Material and Methods: We reviewed the clinical cases of pediatric cataracts diagnosed in the last 12 years at Hospital Pedro Hispano, in Porto. Results: We identified 42 cases of pediatric cataracts with an equal gender distribution. The mean age at diagnosis was 6 years and 64.3% of patients had bilateral disease. Decreased visual acuity was the commonest presenting sign (36.8%) followed by leucocoria (26.3%). The etiology was unknown in 59.5% of cases and there was a slight predominance of nuclear type cataract (32.5%). Cataract was associated with systemic diseases in 23.8% of cases and with ocular abnormalities in 33.3% of cases. 47.6% of patients were treated surgically. Postoperative complications occurred in 35% of cases and posterior capsular opacification was the most common (25%). Discussion: The report of 42 cases is probably the result of the low prevalence of cataracts in this age. Although the limitations of our study include small sample size, the profile of children with cataracts in our hospital has characteristics relatively similar to those described in the literature.

  • Toolkit for Glaucoma Management in Sub-Saharan Africa
    A Toolkit for Glaucoma Management in Sub-Saharan Africa 2 A Toolkit for Glaucoma Management A Toolkit for Glaucoma Management in Sub-Saharan Africa Thanks to financial contribution from the Else Kröner Fresenius Stiftung (Germany), Light for the World launched its first multi-country Glaucoma programme called “Addressing Challenges of Glaucoma - the Silent Thief of Sight” aiming to improve glaucoma services in Burkina Faso, Mozambique and Ethiopia at the end of 2018. As one of the first interventions of this programme, in February 2019, a group of high-level glaucoma experts and general ophthalmologists came together for a workshop in Addis Ababa, Ethiopia, hosted by the Ethiopian Society of Ophthalmology (OSE) to develop a practical toolkit for glaucoma management in Sub-Saharan Africa (SSA). This work was supported by the International Council of Ophthalmology (ICO) and some sections of the ICO Guidelines for Glaucoma Eye Care were adapted for this toolkit. Participants represented all SSA regions as well as global and regional eye health organisations such as the International Council of Ophthalmology (ICO), the International Agency for the Prevention of Blindness (IAPB), the College of Ophthalmology for Eastern, Central and Southern Africa (COECSA), the Francophone African Ophthalmic Society (SAFO), the West African College of Surgeons (WACS), the African Glaucoma Consortium, the Ethiopia, Ghana, Nigeria and South Africa Glaucoma and Ophthalmological Societies, as well as the scientific community and major international training institutions. The group was able to develop the crucial outline for a practical toolkit on glaucoma management for SSA which will complement the important resources existing already, such as the ICO Glaucoma Guidelines.

This article is published with open access Abstract Congenital and childhood cataracts are uncommon but regularly seen in the clinics of most paediatric ophthalmology teams in the UK. They are often associated with profound visual loss and a large proportion have a genetic aetiology, some with significant extra-ocular comorbidities. Optimal diagnosis and treatment typically require close collaboration within multidisciplinary teams. Surgery remains the mainstay of treatment. A variety of surgical techniques, timings of intervention and options for optical correction have been advocated making management seem complex for those seeing affected children infrequently. This paper summarises the proceedings of two recent RCOphth paediatric cataract study days, provides a ‘ ’ 1234567890();,: 1234567890();,: literature review and describes the current UK state of play in the management of paediatric cataracts.

Gaafar Ophthalmology Department, Ophthalmic Center, Mansoura University, Egypt ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ Abstract Purpose: to study the prevalence and the different epidemiological aspects of pediatric cataract in our locality. Methods: A retrospective study included reviewing of medical records of children (≤18 years) diagnosed with cataract, recruited from the Mansoura ophthalmic center, Egypt from 2010 to 2015. The charts were reviewed to gather epidemiological, clinical and surgical data. Results:A total of records of 1320 eyes (940 patients) were retrieved. Median age at diagnosis was 6 years (2 days - 18 years). Almost half (52%) of them were male. The ratio of unilateral to bilateral cataracts was 1.2 to1. Positive family history was found in 212 (22.5%) of the patients. Most of the congenital cataract (CC) cases were idiopathic (37%). Traumatic cataract was the most common diagnosis in acquired cases (83%). Leukocoria was the most common presenting symptom in CC (63%).Visual impairment was more common in acquired cataract (57%).Nuclear cataract was the most frequent type (48%) in CC, while cortical cataract predominated in acquired type (51%).A total of 1288(97%) eyes had undergone cataract surgery with mean follow-up of4±1.6 years. Conclusion:Pediatric cataract represents a true challenging condition in our locality. Key words: Cataract; congenital; Dakahlia, Egypt; epidemiology; Pediatric.

Cases: Similar to the previous reports there were characteristic demarcation of thickened margins on the posterior capsule defects and white dots on the anterior vitreous face in all of our cases. In addition to previous reports, we detected a semi-transparent membrane at the location of the posterior capsule defect bilaterally in all of our cases. Observations: This membrane was loosely attached to the borders of the posterior capsular opening and we removed it with vitreus cutter in two cases and with forceps in the other. In two cases the membranes covered the entire posterior capsular defect area; but in one case the membrane covered only the half of the defect. The cases were managed by standard irrigation – aspiration and anterior vitrectomy. Conclusion: Ophthalmologists should be aware that in some congenital cataracts, they may notice congenital posterior capsular defects with accompanying membranes. Introduction fibers, but it was loosely attached to the borders of posterior capsule defect.
