Intranasal corticosteroids do not affect intraocular pressure or lens opacity: a systematic review of controlled trials.

BACKGROUND: Intranasal corticosteroids (INCS) are prescribed for the long-term prophylactic treatment of inflammatory upper airway conditions. Although some systemic absorption can occur via topical routes, the clinical relevance is controversial. The effects of orally administered corticosteroids on intraocular pressure (IOP) and lens opacity (LO) are well established, but the impact of the INCS is less well defined. This study aims to systematically review the literature for evidence of adverse occular events with INCS use. METHODOLOGY: A systematic review of literature from Medline and Embase databases (January 1974 to 21st of November 2013) was performed. Using the PRISMA guidelines, all controlled clinical trials of patients using INCS, that reported original measures of IOP, LO, glaucoma or cataract incidences were included. Studies with adjuvant administration of oral, inhaled and intravenous steroids were excluded. RESULTS: 665 articles were retrieved with 137 were considered for full-text review. Of these, 116 (85%) were literature reviews and two were case reports. 19 studies (10 RCTs, 1 case-control, 8 case series) were included for the qualitative review, of which 18 reported data on IOP and 10 on cataract/LO. None (n=0) of the 10 RCT reporting data on glaucoma or IOP demonstrated changes in IOP compared to control. Also none (n=0) of the 6 RCTs reporting cataract or lens opacity demonstrated changes compared to control. CONCLUSION: Data from studies with low levels of bias, do not demonstrate a clinically relevant impact of INCS on neither ocular pressure, glaucoma, lens opacity nor cataract formation.

Incidence of neoplasia in patients with unilateral epiphora.

BACKGROUND: Nasolacrimal duct obstruction is common and is usually a result of benign stricture formation.Although neoplasia near or around the lacrimal system may produce epiphora, the incidence of neoplasia from within the lacrimal system as a cause of nasolacrimal duct obstruction is not well documented. METHODS: A retrospective study was performed on all patients undergoing dacryocystorhinostomy with a history of epiphora. The incidence of patients with operative findings of intra-lacrimal neoplasm was sought. Histopathologically confirmed cases were included. RESULTS: The study comprised 537 patients, who underwent a total of 631 endoscopic dacryocystorhinostomy procedures between January 1998 and July 2013. Non-stenotic causes of nasolacrimal duct obstruction were encountered in 3.01 per cent of dacryocystorhinostomy procedures, and included neoplastic, inflammatory and infectious pathologies. Inverted papilloma was the most common cause, encountered in 0.79 per cent of dacryocystorhinostomy operations. CONCLUSION: These findings suggest that neoplasia is an uncommon but not a rare cause of nasolacrimal duct obstruction. Surgical teams performing high numbers of dacryocystorhinostomy procedures should be aware of such pathology and patients counselled appropriately.

Bilateral primary optic nerve lymphoma.

A 69-year-old man was examined for bilateral infiltrative optic neuropathy. Optic nerve biopsy confirmed a malignant B cell lymphoma. Systemic examination and investigations failed to show involvement of other sites.

Esophageal adenocarcinoma metastatic to the orbit.

A 75-year-old woman presented with orbital and ethmoidal metastases from an esophageal adenocarcinoma 6 months after diagnosis of the primary.

Five year incidence of cataract surgery: the Blue Mountains Eye Study.

AIMS: To assess the 5 year incidence of cataract surgery in an older population based prospective cohort. METHODS: 5 Year prospective follow up of the population based Blue Mountains Eye Study (BMES) performed in 1992. The follow up study examined 2335 survivors (75.1%) of the 3654 baseline participants. Baseline and 5 year slit lamp and retroillumination lens photographs were graded for presence of cortical, nuclear, or posterior subcapsular cataract using the Wisconsin cataract grading method and cataract surgery was documented from the history and the clinical examination. RESULTS: An overall cataract surgery rate of 5.7% in first or both eyes was documented. The incidence was 0.3% in people aged 49-54 years at baseline, 1.7% for ages 55-64 years, 7.9% for ages 65 to 74 years, and 17.4% in people aged 75 years or older. The rate of surgery in first or both eyes was 6.0% in women and 5.2% in men, age adjusted p = 0.66. Bilateral cataract surgery was performed during follow up on 2.7% of participants, while 43.1% of unilateral phakic cases had second eye surgery. Presence of any posterior subcapsular (PSC) cataract, either alone or in combination with other cataract types, was the most likely type of cataract at baseline to be associated with incident cataract surgery. Baseline age was the most important non-ocular variable predicting incident cataract surgery. CONCLUSIONS: This study has documented age specific rates for 5 year incident cataract surgery in an older community. The finding of relatively similar incidence rates and ocular predictors of cataract surgery to those reported by the Beaver Dam Eye Study, Wisconsin, United States, is of interest, given previous documented similarities between these two populations.
