ABSTRACT
Objectives: A clinical study of visual outcome and intraocular pressure control after cataract surgery in Lens Induced Glaucoma. Material and methods: A minimum of 50 cases of lens induced glaucoma were selected based on simple random sampling, who attended the department of Narayana Medical College Hospital and were diagnosed to be having Lens Induced Glaucoma. Appropriate medical management was given followed by surgical intervention. Patients were followed up on the 1st week, 4th week and 6th week postoperatively. Results: Finally after the analysis of the data, it was demonstrated that the longer the duration of symptoms and higher intraocular pressure (IOP) at presentation, the poorer the visual prognosis. It was also noticed that the intra-operative and postoperative complication were more in cases of LIG as compared to normal population. It was also noticed that after cataract extraction surgery few cases had post-operative IOP above borderline. These cases can be controlled by anti-glaucoma medication and regular follow-up of these cases. If necessary, trabeculectomy may be done in future to control the IOP. Conclusion: The incidence of postoperative uveitis was more in LIG when compared to the normal population and more so if associated with intra-operative complications. The visual recovery was fairly good in all those cases that have undergone treatment quite early. Also the higher the IOP pre-operatively, the prognosis for good vision following surgery is poor. A sustained rise of pressure for a long time was a bad prognostic factor for post-operative development of good vision. It is to be stressed upon, imparting health education and creating awareness regarding cataract and its implications among the rural community, ophthalmic assistants and peripheral health workers.
ABSTRACT
Lens induced glaucomas are a common occurrence in rural areas of India. Early diagnosis and treatment of mature cataract is very important since delayed treatment of lens-induced glaucoma may result in poor visual outcome. An attempt was made to study the pattern and visual outcome in LIG cases attending the Department of Ophthalmology at Government Medical College, Jammu. A total of 25 patients with a diagnosis of LIG were analyzed. Out of these 15(60%) patients had phacomorphic and 10(40%) had phacolytic glaucoma respectively. All the patients were subjected to ECCE with PC IOL implantation. Postoperative BCVA upto 6/12 was achieved in 6(24%) and upto 6/60 in 16(64%) patients. Only three patients showed poor visual outcome. However, all the patients maintained postoperative IOP of < 20mm Hg without any additional antiglaucoma therapy.
