AIM:To review the management of cataract in children in a tertiary hospital in a developing country,and to highlight the challenges therein.· METHODS:The hospital records of children aged 15 years or less that had cataract surgery at University of Nigeria Teaching Hospital,Enugu from 2005 to 2008 were reviewed *** was obtained on bio-data,pre-and post-operative visual acuity(VA),biometry,and type of surgery,use of intraocular lens(IOL) and presence of *** was used for data entry and analysis.· RESULTS:The hospital records of 21 children(26 eyes) were *** were 12 males(57.1%) and 9 females(42.9%).Pre-operative VA could not be assessed in 11 eyes(42.3%),14 eyes(53.9%) had VA jor cause of childhood blindness and low vision in Africa for many *** should be collaboration between Paediatric Ophthalmology Centres in industrialized and developing countries to enhance skill *** and International Non-governmental Organizations can go a long way to facilitate this exchange.

This study investigated the impact of pre-harvest synthetic chemical treatments on the post-harvest bioactive contents,pasting,colour,and thermal properties of borno brown ***(L.)Walp *** of borno brown ***(L.)Walp was planted on an already ploughed,harrowed and ridged plot of land with a portion cultivated as organic and another *** 90 days,mature grains were harvested and analyzed using standard *** showed that a total of 44.33 g bioactive compounds/100g grain was present in the organic borno brown *** grains whereas,20.56 g bioactive compounds/100g grain was present in the non-organic(control).The identified bioactive compounds in the organic grains included[heneicosane(4.50g/100g grain)];[12-Methyl-E,E-2,13-octadecadien-1-ol(4.09/100g grain)];[3-(2-Hydroxy-6-methylphenyl)-4(3H)-quinazolinone(7.40 g/100g grain)];[Methaqualone(9.08 g/100g grain)].The non-organic contained[heneicosane(4.07g/100g grain)];[3-(2-Hydroxy-6-methylphenyl)-4(3H)-quinazolinone(5.09 g/100g grain)];[Methaqualone(10.61 g/100g grain)].Flavonoids,alkaloids,total phenolic,2,2-diphenyl-1-picryl-hydrazl(DPPH)and ferric ion reducing antioxidant power(FRAP)contents of the organic grains were 19 mgRE/100g,3.40 mg/100g,1550 mgGAE/100g,2840μmolTEAC/100g,and 20.08 mmol Fe^(2+)/100g,*** non-organic grains had flavonoids(11.31 mgRE/100g),alkaloids(1.86 mg/100g),total phenolic(1110 mgGAE/100g),DPPH(1779μmolTEAC/100g)and FRAP(12.24 mmol Fe^(2+)/100g).The peak viscosity of 111.52 RVU,final viscosity(141.25 RVU)and pasting temperature(82.01℃)were obtained for the organic grains while non-organic had peak viscosity of 93.10RVU,final viscosity(95.20 RVU)and pasting temperature(80.10℃).The colour parameters L^(*),a^(*),b^(*)and ΔE were 73.10,0.68,14.47 and 12.98 for the organic and 84.25,0.30,21.10,and 0.00,respectively for non-organic *** thermal property showed enthalpy(ΔH)and peak temperature(T_(p))of 3.12 j/g and 78.25℃ f
