- Optic nerve head and fibre layer imaging for diagnosing glaucoma
Cochrane Systematic Reviews, 30-Nov-2015
The diagnosis of glaucoma is traditionally based on the finding of optic nerve head (ONH) damage assessed subjectively by ophthalmoscopy or photography or by corresponding damage to the visual field assessed by automated perimetry, or both. Diagnostic ass
- Optical coherence tomography (OCT) for detection of macular oedema in patients with diabetic retinopathy
Cochrane Systematic Reviews, 7-Jan-2015
Diabetic macular oedema (DMO) is a thickening of the central retina, or the macula, and is associated with long-term visual loss in people with diabetic retinopathy (DR). Clinically significant macular oedema (CSMO) is the most severe form of DMO. Almost
- Optical coherence tomography for diagnosing skin cancer in adults
Cochrane Systematic Reviews, 4-Dec-2018
Early accurate detection of all skin cancer types is essential to guide appropriate management and to improve morbidity and survival. Melanoma and squamous cell carcinoma (SCC) are high-risk skin cancers, which have the potential to metastasise and ultima
- Optical correction of refractive error for preventing and treating eye symptoms in computer users
Cochrane Systematic Reviews, 10-Apr-2018
Computer users frequently complain about problems with seeing and functioning of the eyes. Asthenopia is a term generally used to describe symptoms related to (prolonged) use of the eyes like ocular fatigue, headache, pain or aching around the eyes, and b
- Optical reading aids for children and young people with low vision
Cochrane Systematic Reviews, 12-Feb-2015
Low vision in childhood is a significant barrier to learning and development, particularly for reading and education. Optical low vision aids may be used to maximise the child's functional vision. The World Health Organization (WHO) has previously highlig
- Optimal duration of exclusive breastfeeding
Cochrane Systematic Reviews, 15-Aug-2012
Although the health benefits of breastfeeding are widely acknowledged, opinions and recommendations are strongly divided on the optimal duration of exclusive breastfeeding. Since 2001, the World Health Organization has recommended exclusive breastfeeding
- Optimal intensity and type of leg exercise training for people with chronic obstructive pulmonary disease
Cochrane Systematic Reviews, 5-Jun-2014
Intensity of exercise is considered a key determinant of training response, however, no systematic review has investigated the effects of different levels of training intensity on exercise capacity, functional exercise capacity and health-related quality
- Optimal loading dose of warfarin for the initiation of oral anticoagulation
Cochrane Systematic Reviews, 12-Dec-2012
Warfarin is used as an oral anticoagulant. However, there is wide variation in patient response to warfarin dose. This variation, as well as the necessity of keeping within a narrow therapeutic range, means that selection of the correct warfarin dose at t
- Optimal monitoring strategies for guiding when to switch first-line antiretroviral therapy regimens for treatment failure in adults and adolescents living with HIV in low-resource settings
Cochrane Systematic Reviews, 18-Jan-2011
One of the critical clinical decisions made in antiretroviral therapy (ART) is when to switch from an initial regimen to another due to treatment failure. This complex process requires consideration of multiple factors including: (1) what type of monitori

Cochrane Systematic Reviews, 21-Sep-2016
Ovarian cancer is the sixth most common cancer among women. In addition to diagnosis and staging, primary surgery is performed to achieve optimal cytoreduction (surgical efforts aimed at removing the bulk of the tumour) as the amount of residual tumour is
- Optimal time for initiating antiretroviral therapy (ART) in HIV-infected, treatment-naive children aged 2 to 5 years old
Cochrane Systematic Reviews, 20-Aug-2013
The use of combination antiretroviral therapy (cART) comprising three antiretroviral medications from at least two classes of drugs is the current standard treatment for HIV infection in adults and children. Current World Health Organization (WHO) guideli
- Optimal time for initiation of antiretroviral therapy in asymptomatic, HIV‐infected, treatment‐naive adults
Cochrane Systematic Reviews, 17-Mar-2010
According to consensus, initiation of therapy is best based on CD4 cell count, a marker of immune status, rather than on viral load, a marker of virologic replication. For patients with advanced symptoms, treatment should be started regardless of CD4 coun
- Optimal timing for intravascular administration set replacement
Cochrane Systematic Reviews, 13-Dec-2018
The tubing (administration set) attached to both venous and arterial catheters may contribute to bacteraemia and other infections. The rate of infection may be increased or decreased by routine replacement of administration sets. This review was originall
- Optimisation of antiretroviral therapy in HIV-infected children under 3 years of age
Cochrane Systematic Reviews, 1-Mar-2014
In the absence of antiretroviral therapy (ART), over 50% of HIV-infected infants progress to AIDS and death by 2 years of age. However, there are challenges to initiation of ART in early life, including the possibility of drug resistance in the context of
- Optimisation of chemotherapy and radiotherapy for untreated Hodgkin lymphoma patients with respect to second malignant neoplasms, overall and progression‐free survival: individual participant data analysis
Cochrane Systematic Reviews, 13-Sep-2017
Efficacy and the risk of severe late effects have to be well-balanced in treatment of Hodgkin lymphoma (HL). Late adverse effects include secondary malignancies which often have a poor prognosis. To synthesise evidence on the risk of secondary malignancie
