Acute postoperative endophthalmitis after cataract operation: result of early vitrectomy within 24 hours of presentation.

Objectives: To evaluate result of early pars plana vitrectomy (PPV) within 24 hours of presentation for acute postoperative endophthalmitis after cataract operation, and to determine factors that predict visual outcome.

Methods: Consecutive patients who developed acute postoperative endophthalmitis within 6 weeks after cataract operation were reviewed. Patients were divided into two groups for analysis: (1) those receiving PPV within 24 hours of presentation (early PPV group), and (2) those receiving initial intravitreal antibiotics only without PPV within 24 hours of presentation (IVA group).

Prediction model to predict type 1 retinopathy of prematurity using gestational age and birth weight (PW-ROP).

Purpose: To develop a prediction model for type 1 retinopathy of prematurity (ROP) from an Asian population.

Methods: This retrospective cohort study included 1043 premature infants who had ROP screening in a tertiary hospital in Hong Kong from year 2006 to 2018. The ROP prediction model was developed by multivariate logistic regression analyses on type 1 ROP.

Association between functional status and ocular surface disease among local elderly population in Hong Kong.

: To evaluate the correlation between ocular surface disease (OSD) and functional status among elderly population over 60 years old in Hong Kong.: Chinese subjects above 60 years old were recruited from the Ophthalmology clinic in Hong Kong West Cluster. Subjects demographic and questionnaires to evaluate the functional status were used to correlate with OSD objectively with clinical examination to assess the meibomian gland dysfunction (MGD), corneal staining, Schirmer's test and tear break-up time (TBUT); and subjectively with ocular surface disease index (OSDI).

Clinical features and treatment outcomes of endogenous endophthalmitis: a 12-year review.

Aim: To identify the clinical features and treatment outcomes of endogenous endophthalmitis and investigate prognostic factors of poor visual outcome.

Methods: The clinical records of all patients diagnosed with endogenous endophthalmitis between January 2007 to December 2018 in Prince of Wales Hospital, Hong Kong, China were retrospectively reviewed. Thorough ophthalmological examination findings were recorded in the case note, including visual acuity testing, slit-lamp examination, indirect ophthalmoscopy and B-scan ultrasonography if media opacity precluded fundus viewing.

Analysis of choriocapillaris perfusion and choroidal layer changes in patients with chronic central serous chorioretinopathy randomised to micropulse laser or photodynamic therapy.

Purpose: The purpose of this study was to investigate the signal changes in choriocapillaris flow deficits and choroidal thickness changes using swept-source optical coherence tomography angiography (OCTA) following different treatments.

Design: A double-blind, randomised controlled trial.

Methods: Patients with unilateral chronic central serous chorioretinopathy (CSC) were randomised to receive subthreshold micropulse laser therapy (MLT) or half-dose photodynamic therapy (PDT).

Factors Associated with Poor Eye Drop Administration Technique and the Role of Patient Education among Hong Kong Elderly Population.

Objectives: To identify the risk factors for poor eye drop application technique in treatment-naïve subjects and to assess if patient education can benefit these subjects.

Methods: Chinese subjects above 60 years were recruited. Questionnaires, including Barthel index; Lawton's instrumental activities of daily living (ADL); Fatigue, Resistance, Ambulation, Illnesses, and Loss of Weight (FRAIL) scale; and Montreal Cognitive Assessment (MoCA), were used to correlate with eye drop application technique (before and after patient education) using Spearman correlation analysis.
