[Show abstract][Hide abstract] ABSTRACT: Background. This study evaluated the effectiveness of managing posterior blepharitis (PB) using a novel Posterior Blepharitis Management Protocol (PBMP). Design. Prospective, consecutive case series with 100% followup to one month. Participants. 27 patients (54 eyes) with PB from an Ophthalmology practice in Sydney, Australia. Methods. Each patient's PB was assessed by grading the nature and expressibility of the central lower lid tarsal gland secretions on Compression Of The Eyelid (COTE). Patients were then instructed in detail to undertake daily PB management sessions at home using our modified PBMP. Main Outcome Measures. On a subjective scale, patients compared their symptoms at one month with baseline. COTE scores were reevaluated to assess the objective effectiveness of each individual's PBMP. COTE scoring was described as grades 1 (clear oil), 2 (pus, liquid), 3 (toothpaste-like secretions), and 4 (complete tarsal gland obstruction). Results. Patients reported a mean 77.8% ± 13.5% subjective improvement in symptoms. There was a trend towards improvement in COTE grading at one month compared with baseline: grades 1 (0 to 7.4%), 2a (22.2 to 16.6%), 2b (7.4 to 3.7%), 3 (18.5 to 27.7%), and 4 (51.8 to 44%). Conclusions. PBMP provided a rapid, inexpensive, simple, effective, and safe method of treating PB.

[Show abstract][Hide abstract] ABSTRACT: Iris vascular tufts are rare iris stromal vascular hamartomas. Patients with iris vascular tufts generally remain asymptomatic until presenting with a spontaneous hyphaema or with mild intraoperative pupil margin haemorrhage during anterior segment surgery. This is the first reported case of spontaneous hyphaema from iris vascular tuft related to a documented supratherapeutic International Normalised Ratio as a predisposing factor. At 86 years of age, this patient also represents the oldest documented first occurrence of bleeding from an iris vascular tuft.
An 86 year old Caucasian lady presented with sudden and persisting loss of vision in her right eye, ocular pain and vomiting. She had a supratherapeutic International Normalised Ratio of 3.9 related to Warfarin use. Her intraocular pressure in the right eye was raised at 55 mmHg, with a 1.6 mm hyphaema and multiple iris vascular tufts visible around the entire pupil.
The present case highlights the risk of anticoagulation therapy as a predisposing factor for spontaneous hyphaema and adds to the management considerations for this condition. It also demonstrates the need for Ophthalmologists to be aware of iris vascular tufts as a cause for spontaneous hyphaema, independent of age and systemic associations.
[Show abstract][Hide abstract] ABSTRACT: To assess the efficacy and safety of a noncontact, fluid-based capsular polishing technique (hydropolish) to remove residual cortical fibers (RCFs) and epithelial cells from the posterior and equatorial capsule in phacoemulsification cataract surgery.
Hydropolish involved manual irrigation of the posterior and equatorial capsule after irrigation/aspiration, using a 27-G hydrodissection cannula. This prospective, consecutive, single surgeon controlled trial was conducted at a dedicated ophthalmic surgery center in Sydney, Australia, between December 20, 2006, and July 14, 2010. Single eyes of consecutive patients underwent cataract surgery without use of hydropolish (control group), while those on or after July 21, 2010, underwent hydropolish (intervention group). Corrected distance visual acuity (CDVA) up to 1 month postoperatively, surgical complications, and hydropolish time were documented.
A total of 1531 eyes were included in this study (hydropolish n = 682; control n = 849). After adjusting for age, sex, and nuclear sclerosis grade, no significant difference was found between hydropolish and control groups when preoperative CDVA was compared against postoperative CDVA at 1 day, 1 week, and 1 month (p>0.05).
Hydropolish is a rapid and safe technique that can remove RCFs from the posterior and equatorial capsule in phacoemulsification cataract surgery. It does not compromise postoperative CDVA.

[Show abstract][Hide abstract] ABSTRACT: Detachment of a hydrodissection cannula during a phacoemulsification procedure appeared to produce no adverse sequelae during surgery. Day 1 postoperatively, two nonpenetrating hemorrhagic retinal lesions were identified; there was no evidence of posterior capsular perforation. Day 6 postoperatively, the pupil was temporally peaked by a fine vitreous strand running to the main-port incision in the superotemporal cornea. This was divided with Nd:YAG laser, and argon laser was applied to encircle the two retinal lesions. Postoperative uncorrected visual acuity remained 6/4 at day 1, day 6, and week 4 (3 weeks after laser application) follow-up visits. Surgeons must accept responsibility for confirming the integrity of the cannula and syringe connection before beginning hydrodissection, which can be highly destructive to intracameral structures.

[Show abstract][Hide abstract] ABSTRACT: PurposeFibres are regularly found within the delivery cartridge (DC) and in the anterior chamber (AC) during phacoemulsification cataract surgery (PCS) and postoperatively. The purpose of this study was to identify their frequency and possible significance.SettingDedicated ophthalmic day surgery.DesignProspective, consecutive, single-surgeon, cohort study.Methods
In 639 eyes undergoing PCS, the presence of fibres was documented in or on both the DC and in the AC intraoperatively, and in the AC postoperatively. The intraoperative method of fibre removal was documented. Corrected distance visual acuity (CDVA) was recorded preoperatively, and at day 1, week 1, and week 4 postoperatively. The incidence of clinical cystoid macular oedema (CMO) and endophthalmitis in the retained fibre subcohort was compared with that of the non-fibre subcohort.ResultsA total of 5.2% of the operated eyes had a fibre or fibres in or on the DC, which in all cases was removed with forceps intraoperatively. A total of 14.6% of operated eyes had a fibre or fibres in the AC intraoperatively; these were removed by irrigation/aspiration. Postoperatively, five eyes (0.78%) had a fibre in the AC. There was no significant difference in postoperative CDVA between the fibre and non-fibre subcohorts (P=0.26), and no clinically significant CMO or endophthalmitis in either subcohort.Conclusions
Most fibres seen on the DC or in the eye are sterile and non-inflammatory. However, there have been reports of endophthalmitis attributed to retained fibres. In this study, there were no complications attributable to the fibres, but their removal may minimise any adverse potential.Eye advance online publication, 16 May 2014; doi:10.1038/eye.2014.76.
[Show abstract][Hide abstract] ABSTRACT: Purpose
To evaluate the use of pars plana needle aspiration of retrolenticular fluid in the immediate management of an acute intraoperative rock-hard eye syndrome (AIRES).
Private practice, Sydney, Australia.
Retrospective case series.
Data over an 18-month period were collected to evaluate efficacy, complications, and visual outcomes in patients who had pars plana needle aspiration for management of AIRES, which is an acute intraoperative shallowing of the anterior chamber and a marked increase in intraocular pressure (IOP) during phacoemulsification cataract surgery but without evidence of a choroidal hemorrhage. Preoperative and postoperative (1 day, 1 week, and 1 month) data were evaluated. Resolution of AIRES and postoperative posterior segment status, IOP, and corrected distance visual acuity (CDVA) were the main outcome measures.
Acute intraoperative rock-hard eye syndrome occurred in 6 (1.45%) of 413 surgeries. All 6 patients were women with a mean age of 81 years. Four patients had dense nuclear cataracts. In each case, the anterior chamber depth and IOP normalized immediately after pars plana needle aspiration and the procedure concluded uneventfully. Mild vitreous hemorrhage was observed in 1 patient postoperatively. At 1 month, the IOP was normal in 5 of 6 cases, while the CDVA was 20/12 in 5 of 6 cases.
Although the etiology of AIRES is iatrogenic, immediate resolution was achieved uneventfully with pars plana needle aspiration, which appears to be a safe management technique with satisfactory outcomes.

[Show abstract][Hide abstract] ABSTRACT: To study the hypothesis that in normal patients, changes in eyelid elasticity may occur asymmetrically and in relation to the side on which the individual sleeps.
Prospective, consecutive, single-center study within a large, tertiary-referral ophthalmology department within a university hospital.
This prospective study was carried out consecutively on 262 normal patients. The 3 inclusion criteria were 1) age ≥55 years, 2) absence of facial nerve palsy, and 3) absence of eyelid trauma or surgery. Immediately before the ocular plastic surgeon assessed the patient, each patient was questioned in a separate consulting room by the attending orthoptist as to his or her customary side of sleeping. After detailed explanation, the "history-masked" ocular plastic surgeon then assessed the patient's upper eyelid laxity, the main outcome measurement. This was performed by asking the seated patient to look down and then gently grasping the upper eyelids close to the eyelid margin, just medial to the lateral commissure. The ocular plastic surgeon, with thumbs pronated, simultaneously distracted both upper eyelids superiorly, laterally, and anteriorly. The measured separation of the upper eyelid from the globe conjunctiva was obtained using calipers. Eyelid laxity grading was designated as grade 1: 0 to 1.9 mm; grade 2: 2.0 to 3.9 mm; grade 3: 4 to 9 mm; and grade 4: floppy.
Two hundred sixty-two patients (58% females) who consecutively satisfied the selection criteria were evaluated, of which 70.22% (183/262) patients had significantly greater laxity of the upper eyelid that corresponded to the side on which they customarily slept. An unpaired t test used to compare the eyelid laxity between the sleeping side and nonsleeping side was statistically significant (p < 0.001).
Normal patients demonstrate a correlation between the side on which they historically or customarily sleep and the laxity of their ipsilateral upper eyelid.

[Show abstract][Hide abstract] ABSTRACT: IgG4-related disease (IgG4-RD) is an inflammatory condition of unknown etiology that can cause tumefactive lesions in a number of tissues and organs, including the orbit and ocular adnexa. Diagnostic criteria for IgG4-RD, including pathology and clinical features and pathology, have been recently proposed. This study presents the first case of unilateral acute visual loss secondary to IgG4-related orbital inflammatory disease with orbital myositis that was complicated by severe compressive optic neuropathy. After initial treatment with pulsed intravenous methylprednisolone, followed by rituximab and radiotherapy, there was a marked improvement in orbital inflammation and clinical and radiological improvement in the compressive optic neuropathy. After 9 months of follow up, the orbital inflammatory disease remained in remission.

[Show abstract][Hide abstract] ABSTRACT: The article "Novel grading system for pupillary ruff changes and associated features" by Wong et al in the July 2012 issue of Clinical & Experimental Ophthalmology1 was significant. In this article the authors suggested that the grading of pupillary ruff atrophy may be helpful in evaluating and managing patients with or without pseudoexfoliation (PXF) syndrome. It is well documented that PXF is found in many tissues, including throughout the eye, meninges, pericardium, knee joint, skin, aorta and peripheral vasculature. It is also apparent from recent research that there are numerous systemic connective tissue associations of PXF, many of these having significant cardiovascular implications2 .
