Coronavirus disease-2019 (COVID-19) caused by a novel enveloped, positive sense, single stranded RNA virus called Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) started originally in Wuhan, China. By March 2020, the disease was declared a global pandemic as the virus spread to all major countries in the world. Initially, it was believed that the virus was transmitted through inhalation of respiratory droplets from an infected person. But given the exponential increase in the number of infected people, more modes of transmission were explored. While all possible routes of transmission of this virus are still undetermined many studies implicate the eyes as the initial site of infection and conjunctivitis as an early symptom of COVID-19.....

Several pharmacologic agents are now available for the treatment of DMO including anti-VEGF agents [1-6] and corticosteroids [1-11]. The introduction and frequency of these treatments has coincided with the introduction of less invasive investigating and monitoring systems including OCT [12-17] and fundus related perimetry, also known as microperimetry (MP) [18, 23]. OCT is now well established in the evaluation of DMO, especially with the recent advances with spectral domain models [1-27]. It has contributed significantly to our understanding of the anatomical changes of DMO and the intra-retinal damage and provides a valuable tool for the follow-up of macular oedema [14]. Carpineto, et al. [22] studied the role of MP in evaluating fixation patterns and retinal sensitivity in patients who had clinically significant macular oedema with a .....

Non-infectious, autoimmune anterior uveitis is a significant cause of ocular disease in both dogs, horses, and humans with the potential for significant vision loss. The mainstay of treatment is topical and/or systemic corticosteroids, however, animals, similar to humans, are not uncommonly resistant to therapy. Additionally, prolonged corticosteroid treatment may cause systemic and ocular toxicity. We describe here a case of steroid-resistant uveitis successfully treated with GLS-1027, an immunomodulatory compound that inhibits Th17 maturation and release of multiple inflammatory cytokines involved in the pathogenesis of uveitis. GLS-1027 may provide an alternative as a steroid-sparing therapeutic option......

Congenital achromatopsia is a hereditary form of day blindness caused by cone photoreceptor dysfunction, with an incidence of approximately 1 in 30,000. This inherited disorder is characterized by a lack of color discrimination, nystagmus, photophobia, and low visual acuity (< 0.2). The most typical genetic mutations are autosomal recessive changes in CNGA3, CNGB3, GNAT2, PDE6H, PDE6C, or ATF6. It should not be confused with cerebral achromatopsia, which is an acquired form of total color blindness that can result from illness, trauma, or some other cause. Color plays an essential role in our lives. It can change actions, influence thinking, and cause reactions. As a powerful type of communication, color is irreplaceable. Green means “go” and red means “stop”. Traffic lights send this global meaning. Color vision deficiency, creat.....

In ophthalmology orbit is the main cavity which contains the eyeball and many other structures related to ocular functions. Lacrimal fossa contains the lacrimal sac, nasolacrimal canal contains the nasolacrimal duct whereas the fossa for the lacrimal gland contains the lacrimal gland. There is no difference between lacrimal fossa and fossa for the lacrimal gland. As two different structures had to be described this artificial difference has been made. The optic canal transmits the optic nerve and through supra-orbital notch pass the the supra-orbital nerve and vessels. Cavities are not necessarily hard like bony cavities. There could be soft cavities also which are cystic in nature and usually contain some fluid. Thus, the eyeball itself contains three soft cavities namely anterio.....

Multi-label classification has a great importance in medical data analysis. It means that each sample can associate with more than one class label. Therefore, it represents complex objects by labeling some basic and hidden patterns. The patient may have multiple diseases at one organ, such as the retina, at the same time. The ophthalmological diseases such as diabetic retinopathy (DR) and hypertension, can cause blindness if not classified accurately. The physician can diagnose one disease but may omit the other. Therefore, multi-label classification is essential to handle this situation, which is challengeable by nature. It has many problems, such as high dimensionality and labels dependency. In addition, the retinal image is very difficult to be analyzed as some contents of it has the same features of the diseases. It suffers from the c.....

Congenital cataract (CC)is the most common cause of treatable childhood blindness. It is responsible for 5-20% of the cases of blindness worldwide. However, the incidence of visual impairment may be higher in developing countries [1]. The prevalence of childhood cataract varies from 1.2 to 6.0 cases per 10,000 infants. Pediatric cataracts are responsible for more than one million cases of childhood blind- ness in Asia. In developing countries, such as India, 7.4-15.3% of childhood blindness is due to cataracts [2,3]. Therefore timely removal of a cataract with the subsequent fast visual rehabilitation has paramount value for children. The Congenital Cataracts take an important place in structure of blindness and low vision and are one of the main reasons.....

Background: Advances in genomics continue to enable the discovery of gene variants which cause various inherited ophthalmic disorders. Several case reports have shown an association between keratoconus and retinal disease but whether there is a genetic basis for this is still not known.
Methods: Clinical case study with Pentacam imaging, fundus autofluorescence (FAF), macular optical coherence tomography (OCT), electrophysiology studies, and genetic analysis.
Results: We report three brothers, two of whom have keratoconus and one who was found to have bilateral cone-rod dystrophy. This was supported by color vision and electrophysiology testing, fundus autofluorescence, and macular OCT findings. Genomic data analysis revealed three rare gene variants (MAP3K19, ADGRV1, and PIK3CG) common to the brother with cone-rod dystrophy and one.....
