. Purpose:  To describe the age‐related change in contrast sensitivity seen in 35‐ to 80‐year‐old men in an Australian population. Methods:  The Florey Adelaide Male Ageing Study (FAMAS) is a prospective population‐based study of men aged 35–80 years randomly selected from the north‐west suburbs of Adelaide. We conducted a nested ophthalmic substudy of these men. Contrast sensitivity (CS) was measured at four spatial frequencies (3, 6, 12 and 18 cycles/degree [cpd]) using the Vectorvision CSV‐1000 contrast sensitivity test chart (Vectorvision, Dayton, OH, USA), and results were statistically analysed relative to age and cataract type. Results:  There were 2650 eligible subjects in the FAMAS and 1195 participated (45.1%); 472 of those participated in the ophthalmic substudy. A statistically significant decrease in contrast sensitivity was seen with advancing age at each spatial frequency tested [Generalized estimating equations (GEE) multiple linear regression: p ≤ 0.01]. The decline with age was greatest in the highest spatial frequency (18 cpd) and least in the lowest spatial frequency (3 cpd). Posterior subcapsular cataract caused the greatest reduction in contrast sensitivity at all spatial frequencies, while nuclear cataract caused significant reduction only in the intermediate (12 cpd) and high (18 cpd) spatial frequencies. Cortical cataract failed to reach statistical significance in contrast sensitivity reduction at all spatial frequencies tested. Conclusion:  Contrast sensitivity declines with age in all spatial frequencies tested with a greater decline occurring in the higher spatial frequencies. Age and cataracts are independently associated with contrast sensitivity decline, and posterior subcapsular cataracts caused the greatest reduction at all spatial frequencies.

Half of the BL/SVI causes were potentially avoidable. The data support the need for increased coverage of measles immunization. There is also a need to develop specialized pediatric ophthalmic services for the management of surgically remediable conditions, to provide optometric, low vision and orientation and mobility services. Genetic risk counseling services also may be considered.

The prevalence of POAG in the population aged >or=40 years in central Sri Lanka was 2.3%. POAG in this population was independently associated with increasing age, IOP and axial length.

The use of endoscopic orbital and optic nerve decompression for traumatic optic neuropathy and dysthyroid orbitopathy have been well documented; however, reports on endoscopic decompression for benign orbital apex lesions are scarce. The records of two patients who underwent endoscopic decompression of the bony orbit for progressive visual loss were reviewed. Patient 1 had fibrous dysplasia and presented with headache and visual field defects. Patient 2 had sphenoid wing meningioma and multiple previous attempts of transcranial tumor resection and orbital decompression. Both had progressive visual deterioration and ultimately underwent transnasal endoscopic orbital decompression. Post-operatively, both patients had subjective and objective improvement in visual function and compressive symptoms. No complications from the endoscopic decompression were observed in both patients. Transnasal endoscopic approach may be a viable option for decompression of benign orbital apex lesions.
