A clinical study on causes of small pupil and its management in Small incision cataract surgery

To evaluate the causes of small pupil and its intra-operative complications in SICS.A total of 50 patients presenting to OPD with Small pupil measured after maximal dilation using tropicamide (0.5%) with phenylephrine (1%) e/d administered 4 times at 15 minutes interval were enrolled in this study. Detailed clinical history, prior medication, presence of possible risk factors, underlying co-morbidities and history of trauma were noted for every case. The results drawn from the study out of 50 patients, revealed that 14 cases were associated with Pseudo-exfoliation syndrome, 16 cases with posterior synechiae (11 were associated with chronic uveitis And 5 cases had history of Trauma), 12 cases were associated with DM, 2 patients had history of intraocular surgery, 1 patient was on Tab. Tamsulosin for treatment of BPH. The remaining 5 cases were atonic pupil in old age patients.The current study discusses the causes of Small pupil and its intra-operative complications along with its management. It’s crucial for every cataract surgeon to cope with small pupil manifesting preoperatively and intra-operatively.
