Comprehensive Ophthalmology Free Papers Hypertensive retinopathy was graded according to KEITH WAGNER and BAKER classification (1939). Grade Ι Grade ΙI Grade ΙII Grade ΙV Mild to moderate narrowing or sclerosis of smaller arterioles. Moderate to marked narrowing of arterioles, exaggeration of light reflex, changes at the arteriovenous crossings (AV crossings). [deflection of veins at AV crossings (Salu’s sign)] Along with grade II changes, copper wiring of arteries, banking of veins distal to AV crossings (Bonnet sign), tapering of veins on either side of AV crossings (Gunn’s sign), cotton wool spots , flame shaped hemorrhages. All features of grade ΙΙΙ as well as papilledema. Blood investigations like fasting/random blood sugar levels (to assess diabetic status), total and differential leucocytic counts and ESR were carried out. Complete macroscopic and microscopic urine examination was conducted to rule out urinary or systemic diseases. Tests for HIV and HbSAg were performed. Blood pressure evaluation was done to assess the hypertension status. RESULTS A total of 105 pregnant women visiting the Obstetric out patient department of Mamata General Hospital, Khammam were included in the present study. 30 control group were taken from M.B.B.S students of same age group from Mamata Medical College. In the present study all the cases observed had normal visual acuity in all the trimesters of pregnancy, but visual disturbance has been observed with loss of vision approaching to 6/36 in eclamptic patients during 30 weeks of pregnancy which has recovered to 6/9 in the postpartum period. Among 135 patients, 105 patients were observed with increased pigmentation around cheeks and eyelids termed as chloasma. In this present study, one case of ptosis was observed and the patient was followed for 2 months postpartum which partially improved.

70th AIOC Proceedings, Cochin 2012 0.050; in left eye it is 7.7900 +/- 0.0511, During 2nd trimester the mean corneal curvature in right eye is 7.8587 +/- 0.012; in left eye it is 7.8683 +/-0.0136 as shown in Table 1. Here the mean corneal curvature in both the eyes increased from first to second trimester. The estimated P value for 1st trimester and 2nd trimester corneal curvature in both the eyes is < 0.001. There is significant increase in corneal curvature. 448 Table 2 1st Trimester 3rd Trimester EYE F-ratio MEAN SD MEAN SD P-value CORNEAL RE 48.719 7.7823 0.050 7.8783 0.033 < 0.001 CURVATURE LE 50.248 7.7900 0.0511 7.8867 0.0345
