Glaucoma and pregnancy is an uncommon combination, but it constitutes a very challenging situation for the treating doctor. The challenge is not only controlling the intraocular pressure and preventing glaucoma progression in the mother, but also having to deal with her mental stress and anxiety regarding the safety of her child. The situation is further worsened by the lack of definite guidelines as to how to deal with such patients. Relative rarity of glaucoma in this population restricts any large prospective randomized clinical trials or any large systematic studies. Moreover, none of the existing anti-glaucoma medications is absolutely safe in pregnancy. Current practice patterns depend on some case reports, a few observational studies and a few animal studies that attempt at determining the safety and efficacy of the available medicines. These are then prescribed on the basis of their relative safety in any particular stage of pregnancy or lactation. Newer medications that were released recently in 2018, such as Vyzulta and Rhopressa, presently have limited data to support their safety for use during pregnancy. Laser trabeculoplasty, conventional filtration surgery (of course without anti-metabolites), and minimally invasive glaucoma surgery represent a few non-pharmacological management options. Surgical procedures such as trabeculectomy and tube-shunts or collagen matrix implants, and newer minimally invasive glaucoma surgery procedures such as the gelatin stents are currently being explored and may prove to be viable solutions for severe glaucoma during pregnancy, although they too have their own inherent drawbacks. Management of glaucoma during pregnancy and lactation requires careful consideration of the disease status, gestational stage, US Food and Drug Administration classification and guidelines, and potential benefits and limitations of the various therapeutic modalities. This review focuses on the importance of a multidisciplinary team approach, starting with preconception planning and counseling, determining the treatment options depending on the stage of glaucoma and of pregnancy, and emphasizes the involvement of the patients, their obstetrician, and pediatrician through active discussion regarding the various medical, laser, or surgical modalities currently available or under exploration for use during pregnancy and lactation. The ultimate aim is to achieve an optimal balance between the risks and benefits of any type of intervention, and to customize treatment on an individual basis in order to achieve the best outcomes for both mother and fetus.
Aims: To evaluate the clinical and histological status of tear film in patients with unilateral pterygium. Settings and Design:Cross-sectional, case-control, doubleblinded study. Methods and Material:Cross-sectional study of both eyes of 102 patients with unilateral pterygium was conducted between March 2011 to December 2012. Patients were subject to fluorescein lower tear meniscus height (LTMH) evaluation, fluorescein tear break-up time (TBUT), Schirmer's test (using topical anesthetic), vital staining (viz. fluorescein, Rose Bengal and lissamine staining), LTMH imaging with anterior segment spectral-domain optical coherence tomography (OCT) cornea-anterior module (CAM-L and CAM-S), and conjunctival smear impression cytology. The normal eye acted as control. Statistical analysis used: fisher's t-test and chi-square test.Results: The study comprised of seventy males and thirtytwo females in the age-range 28-76years. The mean fluorescein LTMH, mean TBUT, mean Schirmer's test value, mean OCT CAM-S and CAM-L values in the normal control eyes were 0.36 ± 0.03 mm, 12.3 ± 1.9s, 13.4 ± 2.5 mm, 0.338 ± 0.082 mm and 0.325 ± 0.088 mm, respectively. The comparable values in eyes with pterygium were 0.24 ± 0.03 mm, 8.2 ± 1.4 sec, 9.2 ± 2.4 mm, 0.212 ± 0.046 mm and 0.204 ± 0.058 mm respectively. Goblet cell count was decreased in impression cytology. Conclusions:Both fluorescein and OCT LTMH were found to be significantly decreased (p<0.01) in eyes with pterygium compared to control eyes. Goblet cell count, TBUT and Schirmer's test values were also comparatively decreased. This study thus emphasizes that tear film abnormalities play a role in aetiology of pterygium and hence early institution of therapy for tear film stabilization can help prevent the disease. Keywords: Keymessage:This study emphasizes that tear film abnormalities play a role in aetiology of pterygium and hence early institution of therapy for tear film stabilization can help prevent the disease.
Zoledronic acid is recommended for patients with osteoporosis. To report a case of unilateral anterior uveitis after zoledronate infusion. An osteoporotic patient presented with pain, visual loss, hyperemia, photophobia, and watering from the left eye after zoledronate infusion. Circumcorneal injection, keratic precipitates, cells, and flare suggested anterior uveitis. Her symptoms resolved completely after 20 days of prednisolone acetate with atropine eye drops. Uveitis is a rare complication of zoledronic acid with an unclear mechanism. Proinflammatory cytokines may play a role in pathogenesis. Zoledronic acid may be associated with rare but serious inflammatory ocular adverse drug reactions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
