ABSTRACT
@#OBJECTIVE: To compare the presence and severity of meibomian gland (MG) dysfunction among eyes of female subjects with and without eyelid margin tattoos using infrared meibography and colored photographs. METHODS: This is a cross-sectional, descriptive study that involved 38 Filipino females with and without eyelid margin tattoos. Infrared meibography was performed on the upper and lower eyelids of each eye to assess total or partial MG dropout. Colored photographs were taken to evaluate vascularity, irregularity, thickening of the lid margins, and plugging of MG orifices. Severity of MG dysfunction (MGD) was assessed using Arita’s MGD proposed grading scale. Independent t-test was used to compare MG dropout and other lid margin parameters between the two groups. Prevalence ratio and prevalence odds ratio were calculated to measure the likelihood of MGD among eyes with eyelid tattoos. RESULTS: Seventy-four (74) eyes were included in the study (36 in the tattoo group and 38 in the control group). Scores for abnormal vascularity, irregularity, and thickening of the lid margins were significantly higher in the tattoo group compared to the control group (p<0.0000001). However, plugging of gland orifices scores between the two groups were found to be similar (upper eyelid: p=0.65; lower eyelid: p=0.91). Total MG dropout was significantly greater in the tattoo group (upper eyelid: -1.11 ± 0.82; lower eyelid: 1.37 ± 0.75) compared to the control group (upper eyelid: 0.53 ± 0.83; lower eyelid: 0.45 ± 0.76) (upper eyelid: p=0.003; lower eyelid: p=0.000001) for the upper and lower eyelid, respectively). Analysis of total MG dropout between the two groups showed a prevalence ratio of 2.13. CONCLUSION: Eyelid margin tattoos are associated with several eyelid margin abnormalities and increase the risk of meibomian gland droupout.

Objective@#This study determined the clinical characteristics of retinoblastoma (RB) from 1998 to 2008 and compared the epidemiological and clinical patterns with those of the period from 1967 to 2001.@*Methods@#We reviewed the clinical records of 152 patients with RB from 1998 to 2008 in terms of demographic and ophthalmological data and clinical staging or classification.@*Results@#Sixty-three percent of cases were unilateral and 37% were bilateral. Three (3%) of 95 unilateral cases and 7 (12%) of 57 bilateral cases had family history of RB (p = 0.038). The mean age at onset was 17.8 months for unilateral and 7.4 months for bilateral cases, while the mean age at diagnosis was 26.4 months and 13.7 months respectively. The delay from onset to diagnosis was 69% in unilateral and 56% in bilateral RB groups. Financial cost (71.4%) was the leading reason for delay, followed by misdiagnosis (24.5%), and inaccessibility of medical facility (2.0%). The most common manifestations were leukocoria (77%), extraocular findings of orbital mass (9%), and proptosis (6%). Advanced intraocular stage was seen in 63 – 71.6% among those with unilateral and 56 – 60% in those with bilateral tumor.@*Conclusion@#The onset of disease had not changed over the years, but patients in general were brought earlier for consultation. Most cases presented in the advanced stage. Decreasing the occurrence of extraocular RB through early consultation and treatment can improve patient survival.
