Abstract
Lens induced glaucoma due to hypermature cataract is an important cause of secondary glaucoma. Lens induced glaucoma is a common cause of ocular morbidity. To determine the visual outcome and study the intraocular pressure control post cataract extraction in patients with lens induced glaucoma. This prospective study was done in patients who underwent cataract surgery with lens induced glaucoma visiting the Tertiary Care Centre in Latur, Maharashtra. Fifty cases of lens induced glaucoma satisfying the inclusion criteria were selected & followed up from the time of admission & surgery till 4 weeks post- operatively and factors influencing the final visual outcome were analysed. Chi-Square test was used for comparison & p-value < 0.05 was considered statistically significant. All the cases included in the study had raised intraocular pressure on admission and 48% patients had intraocular pressure between 30-40 mmHg. It was found that good visual acuity can be achieved in LIG presenting within 2 weeks and IOP less than 35mmHg. Forty four percent had a best corrected visual acuity of 6/6-6/12 post operatively. Cases (100%) having abnormal intraocular pressure on admission had normal intraocular pressure after cataract extraction. Positive correlation between duration of symptoms and pre op IOP to the final best corrected visual acuity was found. Awareness, early diagnosis and efficient medical management can control IOP and inflammation, with meticulous surgery and IOL implantation. Lens induced glaucoma due to hyper mature cataract is an important cause of secondary glaucoma in the developing world. The uptake of eye care services by the rural community has also been suboptimal in countries like India where lens induced glaucoma is a common cause of ocular morbidity.
Highlights
Cataract and glaucoma are the leading causes of blindness throughout the world
3 Cataract is annually increasing at an estimated rate of 3.8million in the country, 4 the occurrence of lens induced glaucoma in India is rapidly increasing. 5,6 Timely intervention is important in achieving good results as the pre-operative and post-operative morbidity is more common in eyes with lens induced glaucoma when compared with a simple uncomplicated cataract eventually affecting the visual outcome and prognosis
While examining condition of the other eye it was found that 25 cases (50%) presented with pseudophakia, 21 cases (42%) presented with IMSC, 4 cases (8%) were with normal limit (WNL) but the results were statically insignificant
Summary
Cataract and glaucoma are the leading causes of blindness throughout the world. The foremost cause of blindness in India being cataract, accounts for 62.4%. 1Glaucoma is a chronic, progressive optic neuropathy caused by a group of ocular conditions, which may lead to damage of the optic nerve with loss of visual function and is known to be the most common risk factor known. Lens Induced Glaucoma (LIG), one of the commonest causes of secondary glaucoma due to senile cortical cataracts, it becomes mandatory to recognize and manage it at the earliest to prevent blindness. 3 Cataract is annually increasing at an estimated rate of 3.8million in the country, 4 the occurrence of lens induced glaucoma in India is rapidly increasing. 5,6 Timely intervention is important in achieving good results as the pre-operative and post-operative morbidity is more common in eyes with lens induced glaucoma when compared with a simple uncomplicated cataract eventually affecting the visual outcome and prognosis.

This study emphasizes the importance of patient education, early diagnosis, timely management of all the cases of cataract before they become hyper mature and land up into lens induced glaucoma. 4 In order to evaluate this information, the present study was attempted to assess the visual outcome and intraocular pressure (IOP) control after cataract surgery in lens induced glaucoma in patients attending the tertiary care hospital Health workers should encourage patients with cataract to seek early treatment for better prognosis. 4 In order to evaluate this information, the present study was attempted to assess the visual outcome and intraocular pressure (IOP) control after cataract surgery in lens induced glaucoma in patients attending the tertiary care hospital
