“…Several studies have previously focussed on the pregnancy-related changes in ocular blood flow [7]and IOP [13, 14, 15, 16, 17, 18, 19]. To the best of our knowledge, this study is the first to document the effect of pregnancy on both intraobserver and the intertechnique agreement in IOP measurements using different tonometers.…”

Aim: To evaluate the effect of pregnancy on intraobserver and intertechnique agreement for intraocular pressure (IOP) measurements. Material and Methods: Right eyes of 88 healthy women who were likely to become pregnant and of 94 healthy age-matched females were included in the study. Complete ocular examinations were performed on each eye. IOP measurements were obtained by Goldmann, Schiötz and non-contact tonometers (NCT) during 3-week exam periods before (within 6 weeks of conception) and during pregnancy (first, second and third trimesters) for pregnant cases, and in similar time intervals for control subjects. In each exam period, three readings with each of three separate tonometers were obtained, at least 1 day apart. Intraobserver and intertechnique agreements for IOP measurements were assessed. Results: The mean visual acuity, keratometry and refractive error of both control and pregnant subjects did not change significantly during the study (all p values >0.01). In late pregnancy, pregnant cases demonstrated significant decreases in IOP measurements obtained with each of the three tonometers, and in intraobserver agreement with Goldmann and Schiötz tonometers (all p values <0.01). Intertechnique agreement of both Goldmann and Schiötz tonometers with NCT decreased significantly in the third trimester. Both intraobserver and intertechnique agreement in IOP measurements of control subjects were not found to change significantly during the study (all p values >0.01). Conclusion: IOP significantly decreased in the third trimester of pregnancy. Perfect intraobserver agreement in IOP readings of pregnant subjects was obtained with NCT. This may suggest that NCT is a viable option for IOP measurements during the follow-up of pregnant patients at risk for glaucoma.

“…10,11 Moreover, it has been reported that physiologic changes during pregnancy (especially in late pregnancy) lead to a mild decrease in the IOP compared to the pressure before pregnancy. [12][13][14][15][16][17][18] This change obviates using multiple classes of antiglaucoma medications to control IOP. After delivery, the oral carbonic anhydrase inhibitors were replaced by topical carbonic anhydrase inhibitors and latanoprost in all patients.…”

Background: There are limited data about the effects of anti-glaucoma drugs on pregnancy. The purpose of this study was to observe pregnancies exposed to anti-glaucoma medications. Methods: Six pregnant glaucomatous patients referred to the glaucoma clinic after their first trimesters were advised to continue their medications. In one patient who was on oral acetazolamide, the drug was substituted with topical medications. In the last month of pregnancy acetazolamide was started and all topical medications were stopped. The control group comprised 24 individuals with no systemic disease or exposure to medications and with comparable age and gestational age on delivery. Pregnancy and delivery complications, Apgar scores at one and five minutes, birth weight, congenital anomalies and psychophysical development of children up to two years of age were evaluated. Results: The mean age of the patients was 28.17 years with mean gestational age on delivery of 38.80 weeks. Low birth weight was more common in the case group (p = 0.041). No other side-effects were observed. The one-minute Apgar scores were nine in all newborns and improved to 10 at five minutes. The psychophysical development of all children was normal up to two years after birth. Conclusions: Analysis of pregnancy outcome of six mothers taking topical glaucoma medications showed no adverse effects apart from a small but statistically significant increased risk of having low birth weight.

“…2 The CIP amplitudes were still below the normal average half a year after delivery. The form of the CIP amplitudes changed in pregnancy, with a marked decrease in the relative crest time during the entire pregnancy and was so characteristic that the authors suggested that dynamic tonometry might be introduced as a diagnostic test for pregnancy!…”

“…This drop may last for several months post-partum period. 2 The pregnant ladies also have a reduced diurnal fluctuation in their IOP as compared to their prepregnancy diurnal variation. 3 This drop in IOP in pregnancy is a result of an increased outflow facility, caused by an increased uveo-scleral outflow and a decrease in the episcleral venous pressure consequent to the decreased venous pressure in the upper part of the body.…”

“…The increased outflow facility and the increased progesterone levels inherent in the third trimester help in clearing the pigment from the angle, preventing an IOP rise. 2 There is a transient loss of accommodation in pregnancy and occasionally accommodative weakness and paralysis has been described during lactation. Tear production tends to decrease during the pregnancy with altered composition leading to dry eyes, infection and local trauma.…”

Eye diseases in pregnancy Pregnancy complications Pregnancy physiology a b s t r a c tThe eyes are our window to the world and offer us an island of vision in the sea of darkness.Equally, the eyes are also a window to peep into what is going on in the milieu interior.Pregnancy is a natural state of physiological stress for the body. Each organ system of the body in a pregnant lady behaves at variation than in a non-pregnant state. A complex interplay exists between how the pregnancy affects the eye and how ocular physiology and pathology may lead to the modification of the management of pregnancy. Added to this is the effect of systemic conditions on the eye which gets modified by pregnancy.
