    Pattern of intraocular pressure changes following manual small incision cataract surgery
    (Kathmandu University, 2005) Das, H; Badhu, BP; Panda, A
    Objectives: To find out the pattern of changes in intraocular pressure after manual small incision cataract surgery. Methods: Consecutive patients (291 eyes of 291 patients) undergoing manual small incision cataract surgery were prospectively evaluated for change in IOP. Patients were further divided into two groups based on whether or not sutures were used to close the scleral tunnel. IOP was serially measured at day 1, 1st, 2 nd, 4 th , 6 th, 8 th and 12th week. Results: The mean post operative IOP in eyes where sutures were not applied (12.59± 3.02 mmHg, 12.59±2.34mmHg, 12.54±2.19mmHg and 12.40±2.99 mm Hg at day1, 2week and 4weeks respectively) was lower than that where sutures were used to close the wound (15.57± 3.86mmHg, 14.05±2.52mmHg, 14.43±3.39mmHg at day1, 2weeks and 4 weeks respectively). There was a drop of IOP from the preoperative IOP in both suture (1.15±3.29mm Hg) and non suture (3.29±3.07mm Hg) group at 3 months of follow up. Conclusion: There is a small drop of IOP following sutureless MSICS during long term follow up. Eyes where sutures are applied are more likely to have higher IOP than those without sutures at the initial post operative period. Key Words: Small incision cataract surgery, suture less cataract surgery, intraocular pressure.

    Prevalence of glaucoma in Sunsari district of eastern Nepal
    (Kathmandu University, 2007) Sah, RP; Badhu, BP; Pokharel, PK; Thakur, SKD; Das, H; Panda, A
    Aims: To determine prevalence of glaucoma and glaucoma suspect in subjects 40 years and above in Sunsari district of eastern Nepal. Methods: A community based cross sectional study examining 1600 selected subjects was carried out. In all subjects best corrected visual acuity was determined. Oblique torch light test was used for anterior chamber depth evaluation. Intraocular pressure (IOP) measurements with Perkins tonometer and fundus examination were carried out in the community. Subjects diagnosed as glaucoma suspect were further evaluated in the hospital using slit lamp examination, gonioscopy and Goldmann perimetry. Glaucoma was defined by characteristic disc and visual field changes irrespective of the level of IOP. Results: Of 1600 subjects examined, the prevalence of glaucoma was found to be 0.938%. The prevalences of primary open angle glaucoma, primary angle closure glaucoma, secondary glaucoma and ocular hypertension were 0.562%, 0.125%, 0.250% and 0.500% respectively. Lens induced glaucoma accounted for all the cases of secondary glaucoma. Conclusion: The prevalence of glaucoma in the Sunsari District of Nepal is 0.938%, which is lower than that reported in the neighboring regions. Lens induced glaucoma is highly prevalent as a cause of secondary glaucoma. Key words: Glaucoma, prevalence, Eastern Nepal, secondary glaucoma
