There was no complication found due to the chandelier insertion in early postoperative period. Chandelier endoillumination is a feasible method for retinal visualization under surgical microscope during scleral buckling.

Purpose (1) To describe and validate a newly developed, timed performance-based measures of functional vision-the real-life vision test (RLVT). (2) To determine how RLVT relates to clinical measures and selfreport assessment of visual function and the complex interactions among visual impairment, psychosocial status, and demographic factors. Methods A total of 64 patients with age-related cataract and 45 age-matched controls were evaluated by four types of measurements: (1) demographic, medical, cognitive, and depressive evaluation and the reaction time (RT) testing; (2) clinical measures (visual acuity, contrast sensitivity, stereopsis, and the color perception); (3) the 25-item National Eye Institute's Visual Functioning Questionnaire; and (4) the RLVT. Spearman's coefficients, partial correlation, and multiple regression analysis were conducted to determine the relationship among RLVT, clinical measures, and selfreport assessment of visual function while controlling for confounders. Results Control subjects performed RLVT significantly better than the cataract patients. RLVT correlated well with both clinical and self-report assessments of visual function. All subscales of RLVT remained highly associated with most of the clinical measures, even after adjusting for age, years of education, depression, cognitive status, and the RT. Distance, intermediate and near visual acuity, and binocular contrast sensitivity were significant predictors of the RLVT performances. Conclusions Given the strong relationship among RLVT, clinical measures, and the self-report assessments, our results highlight the potential usefulness of RLVT for assessing the functional vision of cataract patients. RLVT may provide information not obtainable from clinical measures or surveys and therefore it is essential to be incorporated into future ophthalmological practice.

Rationale:Ethambutol-induced optic neuropathy (EON) is a well-known complication that results from the use of ethambutol. The ocular manifestations of EON include painless loss of central vision and cecocentral scotomas in the visual field.Patient concerns:A 75-year-old Chinese Han man suffered from this rare ocular disorder because he took ethambutol for about 8 months.Diagnoses:He was diagnosed as EON based on series of ophthalmic examinations performed.Interventions:Since he has stopped taking this drug for 3 months, we just offered some neurotrophic agents to him.Outcomes:One month later, he came back for return visit. The ophthalmic examinations indicated recovery of the visual function very well.Lessons:The EON is a reversible optic neuropathy if the ocular toxicity is monitored closely among the tuberculosis patients that take ethambutol.
