The Scottish Retinal Detachment Study: 10-year outcomes after retinal detachment repair.

Objective: To address the paucity of long-term data on outcomes following rhegmatogenous retinal detachment (RRD) repair we aimed to establish the 10-year best corrected visual acuity (BCVA), redetachment rate and lens status for patients from the Scottish Retinal Detachment Study.

Subjects: Data from patients who presented with RRD during the original study were collected from clinical records 10 years after repair. Patients were excluded if lacking 10 year follow-up data, and excluded from visual acuity analysis in the case of significant co-morbid ophthalmic disease.

Title - Long term outcomes of vitrectomy and ERM peel: Can pre-operative metamorphopsia measured using the D-Chart help improve surgical candidate selection?

Purpose: To assess the predictive value of pre-operative metamorphopsia, measured using the D-Chart, in patients undergoing epiretinal membrane (ERM) surgery and how this relates to improvement in quality of life after surgery.

Methods: 17 patients from vitreo-retinal surgery clinics at a tertiary ophthalmology centre were recruited when listed for pars plana vitrectomy (PPV) with ERM peel between September 2019 - February 2020. Pre-operatively patients underwent visual acuity (VA), Visual-Function Index 14 (VF-14) and metamorphopsia (D-Chart-Thomson Software Solutions) assessment and answered a questionnaire regarding cardinal ERM symptoms.

Accuracy of biometric formulae in hypermetropic patients undergoing cataract surgery.

Purpose: To audit and analyse the accuracy of current biometric formulae on refractive outcomes following cataract surgery in patients with axial length less than 22 mm.

Methods: A total of 84 eyes from 84 patients with axial length <22 mm were identified from consecutive patients undergoing cataract surgery retrospectively at a single university hospital. All subjects had biometry using the IOLMaster (Carl Zeiss Meditec, Inc, Dublin, CA, USA) and a Sensar AR40 intraocular lens implant (Abbott Medical Optics, CA, USA).

Risk stratifying retinal breaks.

Objective: Argon laser retinopexy has been the primary treatment for retinal breaks for many decades. Prevention of progression to retinal detachment (RD) is the main objective. The benefit of laser retinopexy is well documented, although little has been reported on the risk factors for progression to RD.

Spontaneous resolution of a rhegmatogenous retinal detachment after normal labor and childbirth.

Purpose: The purpose of this study was to describe a patient with an untreated rhegmatogenous retinal detachment, first diagnosed during pregnancy, that underwent spontaneous resolution after normal labor and childbirth.

Methods: Descriptive case report.

Results And Discussion: It has been extensively documented that normal labor and childbirth are safe in the context of rhegmatogenous retinal detachment.

Tear production and corneal sensitivity in diabetes.

Aim: Diabetic patients are at significant risk of developing corneal lesions such as superficial punctate keratitis, recurrent corneal erosions, persistent epithelial defects, and microbial keratitis. The aim of this study was to investigate whether diabetes mellitus is correlated with both reduced corneal sensation and reduced tear production.

Methods: In 25 type II diabetic patients with a history of retinopathy only and in 25 nondiabetic control subjects (age and sex matched), we performed noncontact corneal aesthesiometry and assessed basal tear production using Schirmer's test with topical anesthesia.

Corneal endothelial evaluation after phacoemulsification and silicone oil removal via an anterior approach.

Purpose: To determine the effect of simultaneous phacoemulsification and silicone oil removal via an anterior approach on the endothelial cell density (ECD).

Methods: In this prospective study, the authors measured the ECD before and 6 weeks after surgery using an automatic noncontact specular endothelial microscope. Nine patients underwent phacoemulsification and silicone oil removal via an anterior approach using a closed system and separation of irrigation/aspiration function.

Trypan blue to aid visualization of the vitreous during anterior segment surgery.

We describe the usefulness of intracameral injection of trypan blue to highlight vitreous in the anterior chamber. The technique was used in 3 eyes of 3 patients who had vitreous prolapse in the anterior chamber. Trypan blue 0.

Does a small central Nd:YAG posterior capsulotomy improve peripheral fundal visualisation for the vitreoretinal surgeon?

Background: To evaluate the effect of Nd:YAG capsulotomy for posterior capsular opacification (PCO) on visualisation of the peripheral fundus with scleral indentation.

Methods: Patients undergoing Nd:YAG capsulotomy for PCO were examined pre- and four weeks post- Nd:YAG capsulotomy. In order to give a quantitative measure of visualisation of the peripheral retina, a novel scalar measurement was developed.

Complete occlusion of the anterior capsular opening by fibrocellular membrane associated with retained silicone oil: a clinicopathologic correlation.

Background: To report the clinicopathologic features of a fibrocellular membrane in a pseudophakic eye with retained silicone oil in the absence of any capsular contraction syndrome, necessitating repeat anterior capsulorhexis.

Methods: Clinicopathologic report of a case.

Results: Histopathologic study of the membrane showed absence of any true periodic acid Schiff-positive capsule within the specimen.

Effect of the Honan intraocular pressure reducer in sub-Tenon's anesthesia.

Purpose: To ascertain whether the Honan intraocular pressure reducer (HIPR) has an effect on the preoperative intraocular pressure (IOP), surgeon's assessment of anesthesia, and patients' analgesic experience when sub-Tenon's anesthesia is used for routine cataract surgery.

Setting: Princess Alexandra Eye Pavilion, Edinburgh, Scotland.

Method: Forty-five eyes of 45 patients having routine phacoemulsification cataract surgery were randomized to receive 10 minutes of ocular compression using the HIPR or no compression after administration of sub-Tenon's anesthesia.

Patient comfort during clear corneal phacoemulsification with sub-Tenon's local anesthesia.

Purpose: To assess patient comfort with and without intravenous (i.v.) cannulation during 1-quadrant sub-Tenon's anesthesia during phacoemulsification.
