Visual impairment among the elderly is a major health problem. With advancing age, the normal function of eye tissues decreases and there is an increased incidence of ocular pathology. Demographic studies have shown that age is the best predictor of blindness and visual impairment. The most common causes of age related visual impairment in the elderly are presbyopia, cataracts, age related macular degeneration, primary open angle glaucoma and diabetic retinopathy. Untreated visual impairment leads to physical handicap, increased incidence of fall, depression, social isolation and dependency. Active screening for visual loss in the elderly should be part of the health examination. The elderly should be encouraged to come for formal 1-2 yearly eye assessment for early detection of visual impairment and to treat all associated problems in order to prevent permanent visual loss.

Asia Pac J Public Health, 2007;19(2):23-8.

PMID: 18050560

The objective of this study is to evaluate the relationship between reproductive exposures and age-related cataract among women. This was a hospital based case-control study. The study population included female patients, aged 50 years and above who attended the Eye clinic at the University of Malaya Medical Centre. The outcome measurement was based on ophthalmologic examination by an ophthalmologist. The data on exposure was obtained from face to face interview using a structured questionnaire. In order to reduce the recall bias, patients' medical records were used to substantiate the exposure status. Multiple logistic regression was used to assess the association of age-related cataract with exogenous estrogen usage (HRT and OCP) and duration of menses. Important confounders such as age, history of diabetes, cigarette smoking and steroids usage were controlled for in the analysis. Females with 29 years or less of endogenous estrogen exposure of, have almost three times the risk of developing age related cataract (adjusted OR 3.42: 95% CI: 1.28, 9.16), similarly among those with exposure of 30-32 years (adjusted OR 3.64: 95% CI: 1.08, 12.26). Hormone Replacement Therapy used for more than three years was found to be a protective factor of age-related cataract. There is evidence that reproductive exposure may play a role in reducing the occurrence of age-related cataract among Malaysian women.

3 cases of perforating injury with retention of intra-ocular foreign body are presented. Their clinical presentation, management and final visual results are discussed. Despite the generally poor prognosis associated with these injuries, some cases surprisingly have good visual results.

Medically important solar ultraviolet A. Radiation measurements

Ilyas M, Abdul Aziz D, Tajuddin MR

Int J Dermatol, 1988 Jun;27(5):315-8.

PMID: 3391727

Results from a 6-year study of solar ultraviolet A (UVA) radiation measurements at the equatorial location of Penang (5 degrees N) are presented. On clear days, the diurnal flux reaches a very high dosage of about 3.0 x 10(-2) KWHM-2 around midday. The average daily total flux is in the range of 1.6 x 10(-1) KWHM-2 and does not change much seasonally. The high 83% cloud cover only reduces the incoming flux to about half. The radiation flux represents a lower limit of the incident UVA radiation applicable to much of the equatorial/tropical region.

Interventional cardiologists and risk of radiation-induced cataract: results of a French multicenter observational study

Jacob S, Boveda S, Bar O, Brézin A, Maccia C, Laurier D, et al.

Int J Cardiol, 2013 Sep 1;167(5):1843-7.

Interventional cardiologists (ICs) are exposed to X-rays and may be at risk to develop cataract earlier than common senile cataract. Excess risk of posterior subcapsular cataract, known as radiation-induced, was previously observed in samples of ICs from Malaysia, and Latin America. The O'CLOC study (Occupational Cataracts and Lens Opacities in interventional Cardiology) was performed to quantify the risk at the scale of France.

This study reviewed the trabeculectomies (TEs) carried out in University Malaya Medical Center between 1994 to 1998. One hundred and nine of 132 eyes operated were in the primary glaucoma group of which 63 (47.7%) were of the open angle type and 46 (34.8%) were of the angle closure type. Twenty-three eyes belong to the secondary glaucoma group. Sixty-five eyes had plain or non-augmented trabeculectomy (TE) while 20 were augmented with mitomycin C (MMC) and 11 with 5 flourouracil (5FU). In 31 eyes the plain TEs were combined with extracapsular cataract extraction (ECCE) and 4 with phacoemusification. One case had combined ECCE and augmented trabeculectomy with mitomycin-C. The patients were followed up at 1 month, 6 months, 1 year and 2 years. Ninety-four of 132 (71.2%) eyes had successful surgery with intraocular pressure (IOP) of less than 21 mmHg (tonometric success) at the end of 2 years. Four of these patients needed topical medication for the IOP control. More failures were seen in patients with cystic blebs than those with diffuse blebs. Complications include hypotony, shallow anterior chamber, cataracts and hyphaema. The majority of cases (53%) had no complications.

The Malaysian Cataract Surgery Registry: Profile of Patients Presenting for Cataract Surgery

Salowi MA, Goh PP, Lee MY, Adnan TH, Ismail M

Asia Pac J Ophthalmol (Phila), 2015;4(4):191-6.

PMID: 26172075 DOI: 10.1097/APO.0000000000000068

PURPOSE: To investigate the change in the profile of patients who had cataract surgery at Ministry of Health (MOH) hospitals in Malaysia.

DESIGN: Secondary analysis on Malaysian Cataract Surgery Registry data.

METHODS: The Malaysian Cataract Surgery Registry, a MOH-initiated registry, collects data on patients who had cataract surgery at the 36 MOH ophthalmology departments including demography, causes of cataract, systemic and ocular comorbidity, preoperative visual acuity (VA), operative details, and postoperative outcomes. This article reviews data on patient profiles from 2002 to 2004 and 2007 to 2011.

RESULTS: The coverage of cataract surgery was 91.5% (171,482/185,388). Mean patient age was 64.5 years, and 51.6% were women. A high proportion of patients had hypertension (48.9%), diabetes mellitus (37.1%), and diabetic retinopathy (10.7%). Most had senile cataract (93.4%) and one third had second eye surgery. Most patients (82.0%) had preoperative unaided VA of worse than 6/12. Eyes presenting with unaided VA of worse than 3/60 decreased from 62.6% in 2002 to 47.7% in 2011, whereas those with 6/18 to 3/60 increased from 35.2% to 48.5% (P < 0.001). Patients who had extracapsular cataract extraction had worse preoperative VA than those who had phacoemulsification (81.3% vs 40% had vision worse than 3/60).

CONCLUSIONS: The obvious change in patient profiles was the decreasing number of eyes presenting with worse than 3/60 vision. Compared with developed countries, patients who had cataract surgery at MOH hospitals in Malaysia were younger and had higher associations with diabetes mellitus and diabetic retinopathy.
