Comprehensive Ophthalmology Free Papers Figure 1: IOP Compared among different groups in RE IOP Compared among Different Groups in LE Qureshi IA et. al. (1996) investigated whether or not the high blood pressure found in late pregnancy influences the known ocular hypotensive effect of late pregnancy. In the second and third trimester subjects, they found the mean intraocular pressure was significantly lower than in the non-pregnant control group. The difference between 1st and 2nd, 1st and 3rd, and 2nd and 3rd trimesters of pregnancy were (mean ± s.d) -0.5 ± 1.2(P < 0.05), -1.5 ± 1.7 (P
70th AIOC Proceedings, Cochin 2012 trimester hypertensive and third trimester normotensive pregnant women was RE- P 0.006, LE -< 0.001. Uveitis C-C Chan et. al. observed four pregnant women in their first trimester with chronic non-infectious uveitis and were followed monthly till 6 months after delivery. They found uveitis activity decreased after the first trimester, but flared in early postpartum period. Kubicka-Trzasks A (2004) followed four pregnant women aged 16-21 years with uveitis of unknown etiology. Vitreous flare and cells were present in all cases. They were followed during pregnancy as well as 3-8 months after delivery. In all patients gradual, total regression of intraocular inflammation with the improvement of visual acuity in three cases were noted. This shows that pregnancy has a positive influence on pregnancy. A case of uveitis was observed in the present study with unknown etiology during 2nd trimester presented with chronic non-infectious anterior uveitis and was instructed not to use any medication. Flare and cells present. Gradually the activity got reduced during the course of pregnancy and flared up two months after postpartum period. This shows that pregnancy has beneficial effects in pregnancy. Retinal Changes Significant fundus changes are expected in PIH when compared to normal pregnancy. Focal and less often generalized, retinal arteriolar narrowing is the most common ocular change seen in preeclampsia. Early studies by Wagner found these changes in 40% to 100% of preeclampsia patients, but the study of Schreyer found these changes in only 5 out of 106 cases (4.7%) of preeclampsia and in one of 21 severe preelamptic patients. These studies suggest that arteriolar changes may help to distinguish those patients with preexisting chronic hypertension from those with preeclampsia. Sathish S et. al. reported spasm and narrowing of retinal veins in 70% of cases of toxemia. In the present study we found two cases (13.3%) presenting with headache and pedal edema for 6 days. The blood pressure was above 140/100 mmHg and vision was 6/6 for these cases. Anterior segment examination was normal. 458
