Steroid induced ocular hypertension and glaucoma

Q: I was diagnosed as having a premature development of a cataract in my left eye. The symptoms were discomfort on a sunny day and a feeling that there was something in my eye. No pain, just something there. The ophthalmologist gave me a thorough exam and the diagnosis stated above. He said my right eye had the beginning of one, but it has not been noticed. Besides surgery, are there glasses I could wear or drops that would make it clearer? I also see halos around lights when driving at night. This has been causing me anxiety and of course a fear that it will progress quickly. What course of treatment should I take? The symptoms have been noticeable for about four weeks. — .

Preliminary results from a NCI-sponsored multi-center randomized controlled clinical trial conducted by the Eastern Cooperative Oncology Group (ECOG) of 722 women with previously untreated recurrent or metastatic breast cancer show that women who received bevacizumab in combination with paclitaxel had a statistically significant increase in PFS of 4 months than women who received paclitaxel alone.  The data monitoring committee overseeing the trial recommended that the results of a recent interim analysis be made public because the study had met its primary endpoint of increasing PFS.  Women whose tumors over-expressed HER-2 were not included in the study unless they had previously received trastuzumab (Herceptin) or were unable to receive trastuzumab.  Also excluded were women who had received preventive chemotherapy treatment with paclitaxel within the previous 12 months, as well as women with a prior history of thrombosis or who were on anticoagulants.  Serious hemorrhage and thrombosis were rare in this study.  Women receiving the combination of paclitaxel and bevacizumab had small increases in rates of neuropathy, hypertension and proteinuria than women receiving paclitaxel alone.  Other side effects were similar between the 2 treatment groups.

Steroid induced glaucoma may develop after application of steroid preparations applied to the skin of the eyelids. This elevation occurs most frequently with chronic use, such as in patients with atopic dermatitis. Close IOP monitoring of these patients is essential and consideration of a non-steroidal topical medication, such as tacrolimus and pimecrolimus, should be considered as an alternative. Elevation in intraocular pressure has also been noted with application of steroids on skin that was not periocular, either from ocular contamination or systemic absorption. [22] Patients should be advised to wash their hands after applying dermatologic steroids or to use gloves.

Results. : An intergenic quantitative trait locus (QTL) was identified at chromosome near the 5′ end of HCG22 that attained the accepted statistical threshold for genome-level significance. The HCG22 transcript, encoding a novel mucin protein, was expressed in trabecular meshwork cells, and expression was stimulated by IL-1, and inhibited by triamcinolone acetate and TGF-β. Bioinformatic analysis defined the QTL as an approximately 4 kilobase (kb) linkage disequilibrium block containing 10 common single nucleotide polymorphisms (SNPs). Four of these SNPs were identified in the National Center for Biotechnology Information (NCBI) GTEx eQTL browser as modifiers of HCG22 expression. Most are predicted to disrupt or improve motifs for transcription factor binding, the most relevant being disruption of the glucocorticoid receptor binding motif. A second QTL was identified within the predicted signal peptide of the HCG22 encoded protein that could affect its secretion. Translation, O-glycosylation, and secretion of the predicted HCG22 protein was verified in cultured trabecular meshwork cells.

The second major complication is a steroid related rise in eye pressure, also known as being a "steroid responder".  This usually requires at least 2 weeks of continuous steroid use, and is reversible if the steroid is discontinued.  The rise in pressure can be very high but if often asymptomatic.  It may be more common in people already being treated for glaucoma. If a person has glaucoma or has a history of steroid related eye pressure problems, they should consult with an ophthalmologist for monitoring of eye pressure if steroid treatment is being contemplated.

Common (1% to 10%): Sinusitis, nasopharyngitis, upper respiratory tract infection , bronchitis
Uncommon (% to 1%): Cough, dyspnea, snoring, dysphonia
Rare (less than %): Pulmonary microembolism (POME) (cough, dyspnea, malaise, hyperhidrosis, chest pain, dizziness, paresthesia, or syncope) caused by oily solutions
Frequency not reported: Sleep apnea
Postmarketing reports: Chest pain, asthma , chronic obstructive pulmonary disease , hyperventilation, obstructive airway disorder, pharyngeal edema, pharyngolaryngeal pain, pulmonary embolism , respiratory distress, rhinitis , sleep apnea syndrome [ Ref ]
