“…The visual acuity in eyes of a large number of subjects improved after refraction (18.9% ≥ 6/ 18 and altogether 37.7%). This reiterates findings from studies conducted in this region (Murthy et al, 2001;Dandona et al, 1999;Nirmalan et al, 2002) for proper use of corrective lenses to improve visual outcome following cataract surgery. After best correction, coincident retinal disease (35.5%) was the most common cause of visual impairment and blindness.…”

I nt r oduction: The Bhaktapur Glaucoma Study is a population-based, cross-sectional and longitudinal study undertaken in one of the districts of Nepal. Objectives: To determine the prevalence of glaucoma in Bhaktapur district, Nepal. Materials and methods: Thirty clusters were randomly selected and a door-to-door census was conducted to identify citizens 40 years of age and older. Four thousand eight hundred individuals fulfilling the eligibility criteria were referred to the base hospital in Kathmandu for a detailed clinical examination. The diagnosis of glaucoma was based upon criteria described by the International Society for Geographic and Epidemiological Ophthalmology (ISGEO). Results: Complete data was available on 3991 subjects (response rate 83.15 %). The mean IOP was 13.3 mm Hg (97.5 th and 99.5 th percentiles, 18 and 20 mm Hg, respectively) and mean VCDR 0.26 (97.5 th and 99.5 th percentiles, 0.6 and 0.8 mm Hg, respectively). Seventy-five subjects had glaucoma, an age-sex-standardized prevalence of 1.80 (95 % confidence interval (CI), 1.68 -1.92). The age-and sex-standardized prevalence of POAG was 1.24 % (CI, 1.14 -1.34), PACG 0.39 % (CI, 0.34 -0.45) and secondary glaucoma 0.15 % (CI, 0.07-0.36). The prevalence of glaucoma increased with increase in age and there was no significant difference in gender. Nine eyes were blind and two subjects bilaterally blind from glaucoma. Conclusion: The overall prevalence of glaucoma was 1.9 %. POAG was the most common form of glaucoma. Visual morbidity from PACG, however, was higher. A large majority of the subjects with POAG had not been previously diagnosed and had intraocular pressure within the normal range.

“…13 Even though the cataract surgical targets are being met, poor outcomes of cataract surgeries is a major problem in developing countries. 14,15 With the resolution of the corneal edema and inflammation with time there was significant improvement in the visual acuity of the eyes 6 weeks after surgery compared to the visual acuity at discharge recorded at the first assessment.…”

BACKGROUND:Cataract is the leading cause of avoidable blindness in India. Around 4 million people become blind each year because of cataract. AIM: To assess the visual outcome and complications associated with cataract surgery in camp patients operated at a Medical College tertiary hospital. MATERIALS AND METHODS: It was a retrospective study where 412 camp patients underwent posterior chamber intraocular lens implantation surgery over a period of one year. Data was compiled based on demographic characteristics, and post-operative complications. It was graded as per Oxford Cataract Treatment and Evaluation Team (OCTET) definitions on first post-operative day. After one month post-operative complications, best corrected visual acuity and refractive errors were also analyzed. RESULTS: 412 eyes underwent cataract surgery with posterior chamber intraocular lens implantation .The maximum patients were in the age group of 60-69 years, 180 (43.6%) patients., Among these patients 240 were males (58.2 %) and 172 were females (41.7 %). Small incision cataract surgery (SICS) with intraocular lens implant was the commonest surgical method (80%) used. 792 eyes of 412 patients had cataract, of which 596 had the cortical type (75.3 %) and 196 had the nuclear type (24.7 %). Of the cortical type, 428 were immature and 168 were mature cataracts Based on OCTET grading, the most common first post-operative day complication was mild iridocyclitis (26.2%) followed by transient corneal edema in 86 patients. The major postoperative complications after 4 weeks of cataract surgery were pigments on PCIOL in 18 (4.36%) cases and capsular flap in 12 cases. After 4 weeks post-operative best corrected visual acuity of eye 6/18 in 89.8% cases. The commonest refractive error was Myopia with against the rule astigmatism seen in 172 out of 300 patients. CONCLUSION: Acceptable results can be obtained from eye camp surgery patients with experienced ophthalmologists in the base hospitals and these camps help in reducing huge burden of cataract patients. Our aim remains to reach more blind and needy patient and to provide an improved standard of visual rehabilitation.

“…Em estudos realizados em outros países em desenvolvimento, a AV foi menor que 0,3 em 35,8% (4) , 51,9% (5) e 24% (6) . Importante lembrar que em alguns países optou-se por deixar os indivíduos em condição de afacia, como em outro estudo, onde 49,4% dos olhos permaneceram afácicos após extração extracapsular (7) , o que resulta em baixa visual bastante importante.…”

“…Nos locais onde a extração intracapsular foi mais freqüen-te, resultados piores foram encontrados (3)(4)(5) . A incidência de complicações cirúrgicas é mais comum na extração intracapsular (14,5%) do que na extracapsular (7,7%) (8) .…”
