Pars plana coreoplasty

The work was carried out on 18 eyes of fifteen patients with inadequate pupillary zone due to different causes. A completely occluded pupil was found in nine eyes [50%] while after cataract and retained lens matter was present in eight eyes [44.4%] and a seccluded pupil with a papillary membrane was the presenting sign in one eye [5.6%]. Preoperative ultrasonography [A and B mode] was carried out for 10 eyes [55.5%]. Pars plana coreoplasty with anterior vitrectomy was done for all the selected eyes. Anatomical success was achieved in all of the operated eyes [100] while visual success was achieved in 86.7% of the operated eyes. The complications and difficulties during and after the operation were recorded

effect of external drainage operations on the scleral rigidity

Eighty eyes with chronic simple glaucoma were operated upon by trabeculectomy, Scheie's modified and iris inclusion operations. The scleral rigidity was measured, before operation and along a period of 30 months postoperatively. The mean coefficient of scleral rigidity was reduced from 0.0251 to 0.0231 in the eyes controlled with operation, from 0.0261 to 0.0240 in the eyes controlled with operation and miotics, and from 00255 to 0.0242 in the uncontrolled eyes with operation and miotics. The cause of reduction in the coefficient of scleral rigidity was the reduction in intra-ocular pressure and the addition of miotics in uncontrolled eyes with operation even with higher pressure
