Abstract :

Aim : To evaluate visual prognosis, intraocular pressure control and complications following manual small incision cataract surgery in eyes with Lens Induced Glaucoma. Materials and methods: This prospective observational study was conducted on 40 patients with lens induced glaucoma from August 2010 to July 2011 at Government Medical College,a tertiary centre. Forty cases presenting with symptoms and signs of lens induced glaucoma were included in the study. All patients underwent slit lamp examination, schiotz tonometry ,gonioscopy, visual acuity assessment and routine investigations pre–operatively. Intraocular pressure was ought under control with topical and systemic anti–glaucoma therapy before surgery. All patients underwent manual small incision cataract surgery. Results : A total of 40 eyes with lens induced glaucoma were included in this study. 87.5 % (35 eyes) cases were ≥ 60 years of age, eldest was 81 years and youngest was 40 years old. Females were 60% (24 eyes) and males were 40% (16 eyes).Pre–operative visual acuity was only perception of light projection of rays in 92.5% (37 eyes). Faulty projection of rays was in 7.5% (3 eyes). Pre–operative mean intraocular pressure was 37.25 mm of Hg and post–operative mean intraocular pressure was 18.07 mm of Hg. There was a clinically significant difference between intraocular pressure at presentation and intraocular pressure at last follow up. Final post–operative visual acuity was ≥ 6/18 in 37.5% (15 eyes) and <6/18 to 6/60 in 37.5 %( 15 eyes). Thus 75% (30 eyes) cases had improved visual acuity to clinically significant level. Visual acuity was < 6/60 to 3/60 in 5% (2 eyes) cases, 20% (8 eyes) cases had visual acuity of <3/60 to finger counting close to face. Conclusion : To conclude the blindness due to lens induced glaucoma is avoidable and curable by timely intervention but there is need to increase the awareness of this condition in general population.
