Complications and visual outcome of sclerally fixed posterior chamber intraocular lenses

Hundred eyes of 97 patients were operated for determining complications and visual outcome of Sclerally Fixed Posterior Chamber Intraocular Lenses at Institute of Ophthalmology, Mayo Hospital, Lahore from January 2002 till December 2002. Those operated either had ICCE done previously, per-operated large rent in posterior capsules, dislocated lens and t raumatic subluxated cataractous Iens. Immediate complications were transient rise in IOP, corneal edema, striate keratopathy. Late complications noted had decentration of IOL [4%], Cystoid Macular edema 4%, suture erosion [2%] and lens tilt [1%]. 80% patients had Post-operative V/A of 6/6-6/12 and 20% had V/A 6/18- 6/60 as compared to Pre-Operative V/A of 56% in 6/6-6/12, 10% in 6/18-6/60 and 34% in 3/60-PL+ ve. Encouraging results favour this procedure

Magnitude of vitamin A deficiency in poor communities of the four selected districts of Punjab using - [rapid assessment technique]

To determine the prevalence and associated factors responsible for vitamin A deficiency [VAD], a survey was carried out in the 21 selected villages of the 4 selected districts of Punjab, using a rapid assessment technique in July-August 1998. A total of 1526 pre-school going children from 6 months to 6 years were examined for Night Blindness [XN], Bitot's Spots [X1B] and Corneal Scars [XS]. Prevalence of VAD came as 6.4% [97 cases], out of which 0.8% [12 cases] were of XN, 5.4% [82 cases] were of X1B and 0.2% [3 cases] were of XS. Male to female ratio was 3:1. Sixty four percent of VAD occurred between ages 4 to 6 years having weights between 15 to 17 kg, which was below the recommended weights. The reason for malnourishment was that majority of VAD cases had diarrhea. Other factors responsible for high prevalence were poor socioeconomic conditions, increased number of children per household, lack of mother's education, low monthly family income, lack of proper breast-feeding, and inadequate usage of vitamin A rich items, like milk and milk products, liver, fish, eggs and mangoes. The reason for not consuming vitamin A rich food was cost of items. The biggest barrier responsible for VAD was poverty. Thus, vitamin A deficiency is a significant major public health problem in the poor communities of Punjab
