COMPARISON OF INTRAVITREAL INJECTION OF RANIBIZUMAB VERSUS LASER THERAPY FOR ZONE II TREATMENT-REQUIRING RETINOPATHY OF PREMATURITY.

PURPOSE: To compare the efficacy of intravitreal injection of ranibizumab (IVR) monotherapy and laser therapy for treatment-requiring retinopathy of prematurity (ROP) in Zone II. METHODS: A prospective, randomized, controlled single-center trial was applied from January 2014 to December 2014; infants who were diagnosed as Zone II treatment-requiring ROP (i.e., Zone II Stage 2 or 3 ROP with plus disease) were randomly assigned to receive IVR monotherapy or laser therapy, and the follow-up interval was at least 6 months. Any eyes that developed recurrence of ROP underwent crossover re-treatment. RESULTS: A total of 100 eyes of 50 ethnic Han Chinese infants were enrolled. At the last follow-up, 26 eyes of 13 infants developed recurrence of ROP in the IVR group and 2 eyes of 1 infant developed recurrence of ROP in the laser therapy group. There was a significant statistical difference in the rate of ROP recurrence between IVR and laser therapy to treat Zone II treatment-requiring ROP (P = 0.001). CONCLUSION: Although IVR appears to regress ROP to certain levels and continue to promote the vascularization of peripheral retinal vessels, a substantial proportion of infants developed recurrence of ROP after a single-dose IVR. Therefore, IVR is not recommended as a single-dose monotherapy for Zone II treatment-requiring ROP.

Scleral sutured aniridia intraocular lens (Morcher®): indications and long-term outcomes.

BACKGROUND/OBJECTIVE: To evaluate the outcomes of trans-scleral sutured posterior chamber black diaphragm intraocular lens (BDIOL) (Morcher®) implantations over 11 years. SUBJECTS/METHODS: Retrospective case-series of patients, who underwent BDIOL implantation, identified from electronic patient records system from 2006 to 2016, Moorfields Eye Hospital. Demographics, pre/post-operative, final best-corrected visual acuity (BCVA), diagnosis, symptomatic improvement, intraoperative and postoperative complications immediate or late were collected and analysed to relate outcomes to surgical indication. RESULTS: Forty eyes of 38 patients (F:M 1:2.8) underwent BDIOL implantation with a mean surgical age of 46.6 years and follow-up of 44.5 months (range of 8-132 months). Indications included 23(57%) ocular trauma, 7(17%) congenital aniridia, 7(17%) iatrogenic lens and/or iris loss, and 3(7%) infectious keratitis. Mean preoperative BCVA was 1.64 logMAR and mean final postoperative BCVA was 0.94 logMAR with an average improvement in BCVA of 0.23 logMAR, equivalent to 1.5 lines of Snellen visual acuity. Visual results varied according to indications. Infectious cause patients had the greatest vision improvement (-0.7 logMAR), followed by trauma (-0.3 logMAR), and 25% of these achieved vision of 0.3 logMAR (6/12 in Snellen acuity) or better. Conversely, the aniridia group had the least improvement (worsened vision of 0.01 logMAR), 17 patients (42%) reported subjective improvement. CONCLUSION: BDIOLs achieve reasonably good visual outcomes in eyes with complex vision threatening pathology. No significant intra-operative complications are documented and most post-operative complications are related to the pre-existing pathology. Post - trauma and iatrogenic aniridia have better outcomes compared to congenital aniridia.

Anxiety and depression in inflammatory eye disease: exploring the potential impact of topical treatment frequency as a putative psychometric item.

OBJECTIVE: To evaluate whether topical therapy is linked to scores related to anxiety, depression and quality of life (QoL) in inflammatory eye disease (IED). METHODS AND ANALYSIS: Patients with ocular surface disease (OSD, N=100) and Uveitis (N=100) completed self-administered validated questions on ocular symptoms and well-being, with supplemental questions on eye drop frequency. RESULTS: Forty (20%) patients had scores consistent with depression and 33 (17%) anxiety. Anxiety, depression, QoL and OSD index (OSDI) scores did not differ significantly between OSD and Uveitis groups. In those with anxiety or depression, QoL was significantly reduced in all WHO Quality Of Life-BREF domains (all p<0.001). Multivariable analysis considering demographic and disease-related factors found daily topical drop frequency to be independently associated with anxiety (p=0.009) but not depression (p=0.300). CONCLUSION: A high proportion of patients with IED demonstrated scores indicative of anxiety and depression. Preliminary evidence suggests that the frequency of topical eye drops potentially plays a significant role in the psychological health status of patients with IED.

BLEB-RELATED ENDOPHTHALMITIS AFTER USE OF THE INVITRIA INJECTION GUIDE.

PURPOSE: To present the case of a patient who developed bleb-related endophthalmitis after an intravitreal injection using the InVitria injection guide, alongside a review of the literature on bleb-related endophthalmitis. METHODS: Our case is presented in context of the current literature on bleb-related endophthalmitis. RESULTS: Bleb-related endophthalmitis occurs in up to 2% of eyes within 5 years of filtering glaucoma surgery. Risk factors include bleb leakage, use of anti-fibrinolytic agents, blepharitis, hypotony, and nasolacrimal duct obstruction. Our patient presented with a bleb leak and bleb-related endophthalmitis 2 weeks after an intravitreal injection using the InVitria injection guide. CONCLUSION: Injection guides can cause bleb trauma and resulting bleb leakage. They should be avoided in patients with filtering glaucoma surgery.

Masquerading optic neuritis.

A 54-year-old woman presented to the ophthalmology emergency department with a 10-day history of blurred vision. The best-corrected visual acuities and Ishihara colour vision were bilaterally reduced with a left relative afferent pupillary defect. Slit-lamp examination was otherwise normal. Retrobulbar optic neuritis (ON) was presumed as she had suffered with this previously and was known to have multiple sclerosis (MS). She was recalled the following week for visual field (VF) testing, which was not available at the time of presentation. VFs demonstrated an incongruous left homonymous hemianopia. She was immediately referred to the medical team to investigate for a stroke, which was subsequently excluded. Thereafter, a trial of pulsed methylprednisolone was commenced, resulting in near complete resolution of the hemianopia. This case demonstrates not only the importance of VF testing, but also how ON may present with any field defect, including mimicking a stroke, a point valuable to ophthalmologists and medics alike.

The eye drop chart: a pilot study for improving administration of and compliance with topical treatments in glaucoma patients.

AIM: In order to improve patient education, compliance, and administration of eye drops prescribed for patients suffering with glaucoma within a UK ophthalmology department, an eye drop chart (EDC) was designed, developed, and piloted with patients attending the glaucoma clinic over 1 month. METHODS: A cross-sectional prospective pilot study of 25 patients using an administration aid and a self-reported questionnaire. Chi-square tests were used to compare responses pre- and postintervention. RESULTS: Results demonstrated an impressive improvement in nine of eleven categories assessed regarding drop administration and compliance. Patients stating that they always wash their hands increased significantly from 64% (13 participants) to 92% (23 participants) (P=0.029), and those who always shake the bottle improved from 40% (10) to 84% (21) (P=0.001). Punctal occlusion techniques improved from 44% (11) to 72% (18) (P=0.015). Finally, patients who always discarded the bottle after 28 days of use rose from 68% to 92%, though the difference was not significant (P=0.09). Only the number of drops being administered to the eye and the length of time left between the application of drops remained relatively unchanged. Sixty-four percent reported finding EDC helpful or useful, 52% had positive responses when asked if they would continue using EDC, and 88% would recommend it to a friend. CONCLUSION: Although there are limitations to the data as they are subjective, descriptive, and limited to sample size of 25, the results of this pilot study have shown promise. The EDC appears to be a cost-effective way at improving patients' use of topical ocular medications.

Retained Descemet's membrane following penetrating keratoplasty for Fuchs' endothelial dystrophy: a case report of a post-operative complication.

PURPOSE: To report a case of retained Descemet's membrane following penetrating keratoplasty in a patient suffering from Fuchs' endothelial corneal dystrophy. The use of confocal microscopy, histopathological tissue analysis, and treatment options are discussed. METHODS: Case report of an 85-year-old man with a past ophthalmic history of atrophic macular degeneration, underwent a penetrating keratoplasty for Fuchs' endothelial corneal dystrophy. Postoperative review revealed a retained retrocorneal membrane within the anterior chamber. Further surgery was performed to excise the membrane, with a subjective and objective postoperative improvement in visual acuity and without subsequent complications of the corneal graft. RESULTS: Histopathological assessment confirmed the clinical suspicion of a retained Descemet's membrane, marrying with the initial histology from the corneal button excised during the penetrating keratoplasty, which showed only a very thin Descemet's layer. CONCLUSION: Retention of the Descemet's membrane following penetrating keratoplasty is a rare but potential complication of this surgery, particularly in cases of Fuchs' endothelial corneal dystrophy due to the thickened and abnormal histological nature of the endothelium and high index of suspicion is required.

Case report: papillitis as the sole ocular sign in Lyme disease.

BACKGROUND: Lyme disease is a spirochetal disease responsible for a multitude of ocular and systemic manifestations, and patients may present to ophthalmologists and general clinicians with a wide variety of generalized and ocular signs which can result in chronic and disabling sequelae. Here we report two cases of patients suffering with Lyme disease who developed a rare associated papillitis. METHODS: A 48-year-old Scottish man presented with diminished visual acuity, painful ocular eye movements, photophobia, and mild ataxia. Fundus examination revealed bilateral disc swelling with associated hemorrhages in the right eye. Following exclusion of raised intracranial pressure as the cause of the findings, enzyme-linked immunosorbent assay and Western blot serology confirmed a positive result for Borrelia burgdorferi which, along with ophthalmic signs and exposure to an endemic area, confirmed the diagnosis of Lyme disease. A 79-year-old gentleman presented with intermittent short-duration "gray film" in his left eye. Fundus examination revealed left optic disc swelling. He was positive for Lyme's serology and his condition was treated with 2 weeks of intravenous ceftriaxone. RESULTS: The first patient's inflammation resolved and visual acuity returned to normal following a course of high-dose steroids and intravenous ceftriaxone, followed by oral doxycycline. The second patient's condition improved with high-dose intravenous ceftriaxone. CONCLUSION: These patients highlight the fact that Lyme disease should be considered as a differential diagnosis for patients presenting with papillitis. With the incidence of this disease rising and more cases being reported, practitioners in Lyme-endemic areas need to be aware of the various manifestations so that appropriate referrals for treatment can be made.
