Red eye is the cardinal sign of ocular inflammation. The condition is usually benign and can be managed by primary care physicians. Conjunctivitis is the most common cause of red eye. Other common causes include blepharitis, corneal abrasion, foreign body, subconjunctival hemorrhage, keratitis, iritis, glaucoma, chemical burn, and scleritis. Signs and symptoms of red eye include eye discharge, redness, pain, photophobia, itching, and visual changes. Generally, viral and bacterial conjunctivitis are self-limiting conditions, and serious complications are rare. Because there is no specific diagnostic test to differentiate viral from bacterial conjunctivitis, most cases are treated using broad-spectrum antibiotics. Allergies or irritants also may cause conjunctivitis. The cause of red eye can be diagnosed through a detailed patient history and careful eye examination, and treatment is based on the underlying etiology. Recognizing the need for emergent referral to an ophthalmologist is key in the primary care management of red eye. Referral is necessary when severe pain is not relieved with topical anesthetics; topical steroids are needed; or the patient has vision loss, copious purulent discharge, corneal involvement, traumatic eye injury, recent ocular surgery, distorted pupil, herpes infection, or recurrent infections.

Tuberculosis is a common disease in India. However, tuberculosis primarily affecting the conjuctiva is a rare entity. We report a 14-year-old girl who presented with unilateral eye discharge, watering, redness and itching for two weeks. Giant papillae were present on the upper tarsal conjunctiva. A provisional diagnosis of allergic conjunctivitis was made. Topical therapy with 1% Prednisolone acetate and 2% Sodium cromoglycate was commenced. The patient returned six months later with no improvement in the symptoms. The tarsal conjunctiva had a polypoidal, velvety appearance with giant papillae. A fibrinous membrane was seen over the tarsal conjunctiva and a preauricular node was found. Excision biopsy and histopathologic examination revealed necrotizing granulomatous inflammation suggestive of tuberculosis. Systemic examination and investigations were normal. She was started on anti-tuberculous therapy. In two months she showed complete resolution of symptoms and marked reduction in papillae and conjunctival thickening. Symptoms and signs of unilateral conjunctivitis may masquerade as primary conjunctival tuberculosis. In an endemic country like India, laterality, chronicity and non-resolution of symptoms with steroids are indications for pursuing a biopsy earlier than later. In our patient, the histopathology clinched the diagnosis of conjunctival tuberculosis resulting in a faster and complete resolution of the disease condition.

Vernal keratoconjunctivitis (VKC) is an unusually severe sight-threatening allergic eye disease, occurring mainly in children. Conventional therapy for allergic conjunctivitis is generally not adequate for VKC. Pediatricians and allergists are often not familiar with the severe clinical symptoms and signs of VKC. As untreated VKC can lead to permanent visual loss, pediatric allergists should be aware of the management and therapeutic options for this disease to allow patients to enter clinical remission with the least side effects and sequelae. Children with VKC present with severe ocular symptoms, that is, severe eye itching and irritation, constant tearing, red eye, eye discharge, and photophobia. On examination, giant papillae are frequently observed on the upper tarsal conjunctiva (cobblestoning appearance), with some developing gelatinous infiltrations around the limbus surrounding the cornea (Horner-Trantas dot). Conjunctival injections are mostly severe with thick mucus ropy discharge. Eosinophils are the predominant cells found in the tears and eye discharge. Common therapies include topical antihistamines and dual-acting agents, such as lodoxamide and olopatadine. These are infrequently sufficient and topical corticosteroids are often required for the treatment of flare ups. Ocular surface remodeling leads to severe suffering and complications, such as corneal ulcers/scars. Other complications include side effects from chronic topical steroids use, such as increased intraocular pressure, glaucoma, cataract and infections. Alternative therapies for VKC include immunomodulators, such as cyclosporine A and tacrolimus. Surgery is reserved for those with complications and should be handled by ophthalmologists with special expertise. Newer research on the pathogenesis of VKC is reviewed in this article. Vernal keratoconjunctivitis is a very important allergic eye disease in children. Complications and remodeling changes are unique and can lead to blindness. Understanding of pathogenesis of VKC may lead to better therapy for these unfortunate patients.

S-1 is an oral antineoplastic agent containing tegafur, gimeracil, and oteracil potassium. Recently, ophthalmic disorders, particularly epiphora, have been reported. We retrospectively investigated the incidence of ophthalmic disorders in patients treated with a regimen containing S-1 at our institution. Ophthalmic disorders were noted in 28 of 261 patients(10.7%). These included epiphora(17 cases), eye discharge(10 cases), conjunctivitis(6cases ), blurred vision(3 cases), and eye discomfort(2 cases), as well as eye pain, pruritus, dry eye, hordeolum, and visual loss(1 case each). The median time from starting treatment to appearance of the condition was 3.0(interquartile range 1.5-4.5)months and the median cumulative S-1 dose was 4.2(interquartile range 2.2-9.5)g. More men than women developed ophthalmic disorders on S-1. The median total dose and duration of treatment were higher in those developed ophthalmic disorders than in those who did not (12.4 g vs 6.3g and 8.6 months vs 4.4 months). Epiphora was the most common of a number of ophthalmic disorders seen in our patients treated with S-1. Patients and physicians should be fully informed of the potential association between S-1 and ophthalmic disorders, and patients receiving this treatment need to be carefully monitored.

There have been increasing reports of skin manifestations in COVID-19 patients. We conducted a systematic review and included manuscripts describing patients with positive RT-PCR coronavirus testing from nasopharyngeal swabs who also developed cutaneous manifestations. A total of 655 patients were selected, with different types of skin rashes: Erythematous maculopapular (n = 250), vascular (n = 146), vesicular (n = 99), urticarial (n = 98), erythema multiforme/generalized pustular figurate erythema/Stevens-Johnson syndrome (n = 22), ocular/periocular (n = 14), polymorphic pattern (n = 9), generalized pruritus (n = 8), Kawasaki disease (n = 5), atypical erythema nodosum (n = 3), and atypical Sweet syndrome (n = 1). Chilblain-like lesions were more frequent in the younger population and were linked to a milder disease course, while fixed livedo racemosa and retiform purpura appeared in older patients and seemed to predict a more severe prognosis. For vesicular rashes, PCR determined the presence of herpesviruses in the vesicle fluid, which raised the possibility of herpesvirus co-infections. The erythema-multiforme-like pattern, generalized pustular figurate erythema and Stevens-Johnson syndrome were most frequently linked to hydroxychloroquine intake. A positive PCR determination of SARS-COV-2 from conjunctival swabs suggest that eye discharge can also be contagious. These cutaneous manifestations may aid in identifying otherwise asymptomatic COVID-19 carriers in some cases or predict a more severe evolution in others.
