The purpose to do this research was to find out the habits of contact lens wearers towards lens care in this country, and to evaluate the compliance of contact lens wearers.
Methods: All respondents underwent an interview regarding
questionnaire which was carried out at the Klang Valley and
Sabah, Malaysia by trained bilingual optometrists. The
questionnaire was obtained from a study by Yvonne Wu et
al., 2010. The questionnaire included information about
respondents' demographics, contact lens hygiene behaviors
and attitudes toward lens care. Comparison between groups
and certain factors of lens care were analyzed.
Results: Within the 100 respondents, 74% were female. The
majority used monthly disposable lens (53%, 53/100), 35%
(35/100) wore daily lens, 3% (3/100) wore biweekly
disposable lens, 8% (8/100) wore quarter-yearly (3 months)
lens, and only a participant (1%) used conventional lenses.
The major non-compliance aspect that found out from this
research were poor lens case (46%), inadequate cleaning of
lens before storing (38%) and wearers not remembering how
often they were advised to return for an aftercare (24%).
Conclusion: The poor lens care hygiene, inadequate cleaning
of lens before storing may due to lack of proper advice to the contact lens wearers during examination or lack of
awareness of aftercare visit.

The purpose of this study is to describe the correlation of findings between results from spectral domain optical coherence tomography (SD-OCT) and microperimetry in a case series regarding patients with Goldmann-Favre syndrome. Goldmann-Favre syndrome is a rare autosomal recessive hereditary vitreo-retinal degeneration that impacts the functionality of vision in subjects. Three men with this condition were assessed and subjected to microperimetry and SD-OCT. Two of the men were brothers. This study finds that the retinoschisis and macular cystoid changes noted in the SD-OCT matched the scotomas revealed by the microperimetry. The findings of each of the individual cases are reported herein.

3.Tear film measurements in four different ethnic groups: Malay, Chinese, Indian and Nigerian
International Eye Science 2020;20(4):589-593
AIM: To compare the non-invasive tear film break-up time(NIBUT), tear break up time(TBUT), basal tear secretion(BTS)and blink rate in four ethnic groups: Malay, Chinese, Indian and Nigerian.
METHODS: Totally 120 healthy(61 males and 59 females)subjects(without dry eye symptoms and ocular surface disorder)with the age 20 to 39 years were recruited; 30 were Malays, 30 were Chinese, 31 were Indians and 29 were Nigerians. Based on McMonnies questionnaire and clinical examination, normal subjects were selected. NIBUT, TBUT, BTS were assessed in only one eye(right)of each subject and blink rate was also assessed.
RESULTS: There was significant difference in the NIBUT, TBUT, BTS and blink rate among 4 different ethnic groups(P=0.018),(P=0.001),(P=0.011), and(P=0.004)respectively. No statistically significant difference of NIBUT, TBUT, BTS and blink rate was found between the genders among different ethnic groups. Indian had higher median for NIBUT(10±6s), TBUT(7±5s)and BTS(20±20 mm)than others races. Chinese had lower median for NIBUT(7.5±4s)and TBUT(4±2s)while Malay had low BTS(9.5±16 mm)among the groups. There was no significant correlation of blink rate with NIBUT, TBUT and BTS(r= -0.119, P=0.195),(r=-0.086, P=0.352),(r= -0.123, P=0.180)respectively.
CONCLUSION: This study showed the variability in tear-film measurements values in four ethnic groups.
