Abstract

PURPOSE
To report clinical features of patients with retinal and choroidal diseases presenting with acute visual disturbance during pregnancy.
METHODS
In this retrospective case series, patients who developed acute visual loss during pregnancy (including puerperium) and visited a tertiary hospital from July 2007 to June 2015, were recruited by searching electronic medical records. Patients were categorized according to the cause of visual loss. Clinical features and required diagnostic modalities were analyzed in the retinal and choroidal disease group.
RESULTS
Acute visual loss occurred in 147 patients; 49 (38.9%) were classified into the retinal and choroidal group. The diagnoses included central serous chorioretinopathy (22.4%), hypertensive retinopathy with or without pre-eclampsia (22.4%), retinal tear with or without retinal detachment (18.4%), diabetic retinopathy progression (10.2%), Vogt-Koyanagi-Harada disease (4.1%), retinal artery occlusion (4.1%), multiple evanescent white dot syndrome (4.1%), and others (14.3%). Visual symptoms first appeared at gestational age 25.9 ± 10.3 weeks. The initial best-corrected visual acuity (BCVA) was 0.27 ± 0.39 logarithm of the minimum angle of resolution (logMAR); the final BCVA after delivery improved to 0.13 ± 0.35 logMAR. Serious visual deterioration (BCVA worth than 20 / 200) developed in two patients. Differential diagnoses were established with characteristic fundus and spectral-domain optical coherence tomography findings in all cases.
CONCLUSIONS
In pregnant women with acute visual loss, retinal and choroidal diseases are common and could be vision threatening. Physicians should be aware of pregnancy-associated retinal and choroidal diseases and their clinical features. The differential diagnosis can be established with non-invasive techniques.

  Fig. 2 Optical coherence tomography images in enhanced depth image mode of a patient who was diagnosed with central serous chorioretinopathy at gestational age 25 weeks. (A) The image obtained at gestational age 25 weeks. The dilated large choroidal vessels (arrows), which are characteristic of central serous chorioretinopathy, are visible. (B) The image obtained at 2 weeks postpartum.

  Fig. 3 Sequential images of a patient who was diagnosed with and underwent treatment for high-risk proliferative diabetic retinopathy during pregnancy (the sequential images were obtained at gestational age (GA) 22 weeks, GA 29 weeks, 5 weeks postpartum, and 10 weeks postpartum). This patient underwent panretinal photocoagulation at GA 22 weeks and received intravitreal injection of bevacizumab at GA 29 weeks. Wide-angle fundus photographs show rapid progression of tractional membrane and the development of preretinal hemorrhage, and the optical coherence tomography images show aggravation and relief of diabetic macular edema. The patient underwent pars plana vitrectomy for tractional retinal detachment 7 months after delivery.

  Fig. 4 Images of a patient diagnosed with incomplete Vogt-Koyanagi-Harada during pregnancy. (A) Enhanced depth image optical coherence tomography image of the left eye at gestational age 20 weeks revealing serous retinal detachment with subretinal exudation and choroidal thickening (arrows). (B) Enhanced depth image optical coherence tomography image at gestational age 22 weeks revealing that the subretinal fluid resolved after administration of systemic corticosteroid.

  Fig. 6 Initial symptom onset in each disease category. HTR = hypertensive retinopathy; CSC = central serous chorioretinopathy; DR = diabetic retinopathy; RT = retinal tear with or without retinal detachment; RAO = retinal artery occlusion. Symptom onset was significantly different in the HTR group compared with that in the other disease groups (p = 0.002 by the Mann-Whitney U-test), but no differences were observed with the other groups.
