Ophthalmologists evaluate visual acuity tests by the number of correctly recognized optotypes (usually letters) in the different lines of an eye chart. This probability-based scoring results in significant statistical error that can only be decreased by the time-consuming analysis of a larger number of optotypes. In this paper, we present a new, more precise correlation-based scoring method that takes the degree of misidentification into consideration too, rather than the mere fact of it. According to our experimental results, this new method decreases the uncertainty error by 28% if using the same number of optotypes at a given letter size or requires half the optotype number to produce the same error as that of probability-based scoring...

There is debate concerning whether the use of Latanoprost in early postoperative period of cataract surgery and in glaucoma patients with uveitis as it may aggravate the inflammation and results in macular edema (ME), because of blood-ocular barrier disruption. However, there is no solid evidence for disruption of blood-ocular barrier with Latanoprost and aggravation of uveitis or ME formation. Similar to pseudophakic ME, the imaging ME in cases claimed to be secondary to Latanoprost is greater than clinical ME, happens mostly in complicated surgeries, and the vast majority resolve within weeks to months with using a non-steroidal anti-inflammatory drug...

BACKGROUND: Optic disc edema can be an important indicator of serious neurological disease, but is poorly detected using the direct ophthalmoscope. Portable fundus photography may overcome this difficulty. INTRODUCTION: The purpose of this study was to determine the sensitivity and specificity of a handheld, nonmydriatic fundus camera for the detection of optic disc edema. MATERIALS AND METHODS: Retrospective review of nonmydriatic optic disc photographs taken with a portable fundus camera (Pictor Plus; Volk Optical, Mentor, OH) from the University of Michigan Neuro-Ophthalmology Clinics...

Septo-optic dysplasia (SOD) is a congenital anomaly in which agenesis of the septum pellucidum and optic nerve hypoplasia are accompanied by hypopituitarism. Typically, the symptoms develop in 3 organs, the brain, eyes, and pituitary, and approximately one third of the patients present with all of the three cardinal features. The diagnostic criteria for SOD were established in Japan in 2015. The purpose of this study is to review clinical features regarding SOD patients with hypopituitarism in Japan. In this study, 21 patients with SOD were identified by a questionnaire survey for congenital central hypothyroidism...

Treatment of neovascular age-related macular degeneration (AMD) with anti-vascular endothelial growth factor agents has been improved since its introduction in Germany. Several observational studies have demonstrated an increased frequency of injections in parallel with improved visual outcomes during the first year of treatment over the last 7 years. These results are reflected in several case series. However, studies with a longer follow-up reported that visual function regressed to baseline vision following an initial improvement, e...

BACKGROUND: There are only few data on medical problems and utilization of health services of former very low birth weight (VLBW) children at preschool age. STUDY DESIGN: At five years of age parents of a cohort of VLBW children (N=862) received questionnaires, a medical interview and examination. The results were compared to the KIGGS cohort (Deutscher-Kinder-und Jugendgesundheitssurvey, N=777). RESULTS: Parents of the VLBW and KIGGS cohort reported a very good or good health in 95% in their children...

PURPOSE: To quantify refractive changes following horizontal lateral rectus recession and medial rectus resection surgery and to investigate the causes of these changes. METHODS: The medical records of patients who underwent unilateral horizontal lateral rectus recession and medial rectus resection for exotropia by a single surgeon over a period of 14 years were reviewed retrospectively. Using vector analysis, refractive changes in operated eyes (cases) were compared to changes in the sound eyes (controls)...

INTRODUCTION: Diabetic retinopathy (DR) is the emerging cause of blindness in the developing world. Timely detection of DR could save vision from its avoidable blinding condition. OBJECTIVE: To assess the accuracy of DR grading in fundus photographs by the allied ophthalmic personnel (AOP) as compared to ophthalmologist at a community setting in Nepal. MATERIALS AND METHODS: Fundus photographs of known diabetes subjects attending for DR screening were graded by two groups of AOP and ophthalmologist...

A 15-year-old boy presented with progressive myoclonic epilepsy and unbalance gaits for 4 years. Slit lamp examination showed a punctate cataract and funduscopic examination revealed bilateral macular cherry-red spots. Macular scan of spectral domain optical coherence tomography (SD-OCT) showed hyperreflectivity of the inner retinal layer and apparent hyperreflectivity of the photoreceptor layers in the foveal region. The clinical presentations were consistent with a Type I sialidosis which led to genetic analysis and revealed NEU1 mutation in this patient...

The purpose of this study was to demonstrate two cases of vertical diplopia after cataract surgery and to discuss the mechanism and types of strabismus caused by the local anesthesia with retrobulbar injection. Two cases of vertical diplopia after cataract surgeries were reported. They were operated by the same surgeon and both happened to the left eye and both presented with marked left hypotropia. The clinical findings consisted of overacting left inferior rectus (LIR) in case 1 and mixed overacting and restrictive LIR in case 2...

BACKGROUND: Subjective expectations regarding future health may influence patients' judgement of current health and treatment effects, as well as adherence to therapies in chronic diseases. We aimed to explore subjective expectations on longevity and future health-related quality of life (HRQOL) of patients with age-related macular degeneration (AMD) treated with antiVEGF injections and analyse the influencing factors. METHODS: Consecutive AMD patients in two ophthalmology centres were included...

An 82-year-old woman with polymyalgia rheumatica (PMR) on prednisone 7 mg daily was admitted to an acute stroke unit with a right homonymous hemianopia, a left posterior cerebral artery occlusion and occipital lobe infarct. She had raised inflammatory markers, did not have a temporal artery biopsy, and was discharged on the same dose of prednisone. After 21 months, off prednisone, her ophthalmologist, concerned about giant cell arteritis (GCA), restarted prednisone 40 mg daily, with rapid, profound visual improvement...

PURPOSE: Prospective evaluation of family history (FH) of glaucoma and FH of optic disc drusen (ODD) in patients with sonographically confirmed ODD. PATIENTS AND METHODS: A total of 87 patients with ODD interviewed all their first-degree and second-degree relatives using a detailed questionnaire on whether an ophthalmologist had diagnosed or excluded glaucoma or ocular hypertension (OH). Using a second questionnaire, 62 of these patients also provided information about ODD in their FH...

This study was conducted to establish normal reference range for the Schirmer tear test (STT) and intraocular pressure (IOP) in clinically normal donkeys for use in clinical practice. Sixteen adult Ethiopian domestic donkeys were used in this study. Complete ophthalmic examinations were performed without chemical restraint. STT values were evaluated in both eyes of all donkeys using a commercial STT strip. IOP was measured in both eyes with a Tono-Pen Vet (Reichert. USA) without using regional nerve blocks...

OBJECTIVE: Previous studies have suggested an association between dry eye and migraine. In a busy ophthalmologist clinic, quick identification of dry eye in migraine sufferers may improve their quality of life. Tear osmolarity is an objective and reliable tool for diagnosing dry eye. It has not been investigated in any population with migraine. Using tear osmolarity and questionnaires, we aimed to explore the relationship between dry eye and clinical symptoms in patients with migraine...
