UNASSIGNED: We aimed to describe a case of bilateral keratoconjunctivitis after exposure to the toxic sap of Euphorbia lathyris.
UNASSIGNED: A 76-year-old gentleman presented after exposure to E. lathyris whilst he was gardening. He had 6/12 visual acuity in his right eye, and 6/4 in his left. Examination revealed marked periocular dermatitis, conjunctival injection and corneal oedema in the right eye with diffuse punctate epithelial staining. He was treated with ocular irrigation, topical steroids, antibiotics, cycloplegics and lubricants. Over 48 h, his left eye started to become symptomatic. He developed bilateral corneal epithelial defects and anterior chamber inflammation. His visual acuity worsened to 6/36 right and 6/24 left. At his 3-week follow-up, there was marked improvement in the resolution of the toxic keratoconjunctivitis in both eyes.
UNASSIGNED: Toxic sap from E. lathyris can cause severe keratoconjunctivitis. Irrigation of both eyes despite unilateral symptoms and early follow-up should be considered signs of toxicity may only become evident after 24-48 h.

The aim of this article is to report clinical features and therapeutic approach of cicatrizing keratoconjunctivitis secondary to ocular lichen planus based on a case report. The patient is a 77-year-old female with a history of ocular discomfort and recurrent keratoconjunctivitis that did not improve with conservative treatment, as well as a history of oral and nasal aphthous ulcers. After a complete ophthalmologic, dermatologic and anatomopathological study, the diagnosis of ocular lichen planus was established and immunosuppressive treatment was initiated. Most cases of ocular lichen planus are presented as chronic cicatricial conjunctivitis. A correct differential diagnosis, as well as an early detection are essential for the control of this entity and its sequelae. Treatment, based on corticosteroids and immunosuppressants, both topical and systemic, is aimed at controlling inflammation and scarring.

Caterpillars can damage human health, including visual acuity, as a result of penetration of the setae into the eye or their layout on the eye tissue. However, the path of setae movement in the eye remains unclear. In this study, a 43-year-old woman was injured in the left eye by a caterpillar. Other than rubbing her eye, the patient did not attempt any type of treatment, and she visited our outpatient clinic 5 days after the accident. The patient\'s left eyelid was markedly swollen, with a visual acuity of 1.0 in the right eye and only 0.04 in the left eye. Images of the setae in the eye were taken using an oil lens microscope, which showed clearly their detailed characteristics. The setae were removed from the eye as much as possible. Topical eyedrops and oral steroids were used to reduce the inflammation. Vitritis and retinitis occurred at the 6-month follow-up and was classified as ophthalmia nodosa by the ophthalmologist. Before we did our study, some ophthalmologists believed that setae moved forward; however, we found that setae in the eye moved in a disorderly fashion. We also note that all setae should be removed. This case demonstrates that caterpillar setae in the eye move in a disorderly fashion and eventually caused ophthalmia nodosa.

UNASSIGNED: Chronic keratoconjunctivitis is a rare presentation of autoimmune polyglandular syndrome type 1 (APS-1) during the first year of life. Herein, We report a case of a 10-month-old baby girl with chronic bilateral keratoconjunctivitis, corneal scarring and neovascularization that was treated initially with topical immunosuppressants.
UNASSIGNED: Detailed ophthalmological assessment followed by molecular testing using whole exome sequencing.
UNASSIGNED: In addition to the severe chronic bilateral keratoconjunctivitis, corneal scarring and neovascularization, patient weight was found to be low than 10th percentile. Further genetic testing revealed autoimmune regulator (AIRE) gene variant that was only reported once in the literature confirming the diagnosis of APS-1. Further workup detected hypoparathyroidism that was treated with calcium supplementation.
UNASSIGNED: Our case represents the importance of multidisciplinary services and highlights the role of genetic testing in diagnosing such syndromic cases. We reviewed previous reports and found that available treatment for ocular involvement is usually nonsatisfactory; however, early detection and referral by ophthalmologists could result in treating previously undetected endocrine disorders that can be life threatening if left untreated.

OBJECTIVE: The aim of this study was to describe a case of corneal involvement as an early manifestation of ocular disease in the 2022 human mpox (monkeypox) virus outbreak.
METHODS: This is a single case report with longitudinal care.
RESULTS: A 47-year-old immunocompetent man presented with viral conjunctivitis before development of skin lesions or systemic symptoms. Subsequently, he developed membranous keratoconjunctivitis and a corneal epithelial defect. Orthopoxvirus-positive polymerase chain reaction test from his ocular surface was positive. The epithelial defect did not heal with conservative treatment but was successfully treated with amniotic membrane transplantation over 8 days. Reduced corneal sensation was noted after epithelial healing, and polymerase chain reaction from the ocular surface remained positive at 17 days from symptom onset, with slowly recovering conjunctivitis at 21 days. Continued membrane formation required repeated removal but significantly improved with topical corticosteroid treatment after epithelial healing by 29 days of symptom onset. Corneal sensation normalized by 87 days from symptom onset at which time symblepharon were noted but PCR testing from the ocular surface was negative.
CONCLUSIONS: Early corneal involvement of human monkeypox virus is possible. Transient corneal hypoesthesia may be due to acute inflammation. Chronic inflammatory changes can result in symblepharon. These findings have potential implications in patient care and corneal donation.

The recent monsoon rains in Pakistan were unprecedented and caused flooding all over Pakistan, especially in Sindh and Balochistan. Following this national disaster, various water-borne and contagious diseases started erupting all over the country. In such a calamity-struck city of Jacobabad, we started receiving cases with a peculiar set of ocular complaints mimicking viral keratoconjunctivitis. Failure to respond to traditional treatment and the unique appearance of these corneal opacities led to a rare diagnosis of Microsporidial Keratoconjunctivitis, which was later confirmed by microscopy and staining of corneal scrapings of the most affected case. In line with published literature, all cases were treated with topical fluoroquinolone and topical anti-fungal therapy, following which the disease was cleared within a week. The disease has seen an upward trend the world over, especially among Asia. To the best of our knowledge, no such cases have been reported in Pakistan as yet. In this case series, we highlight the strong correlation of emergence of microsporidial keratitis in patients following exposure to pooled water bodies after the monsoon rainy season and floods. Moreover, this report will help create awareness in eye professionals regarding the prevention, timely diagnosis and treatment of these rare and emerging cases. Key Words: Keratitis, Spores, Water-borne diseases, Microsporidia.

Rhabdophis tigrinus (R. tigrinus) is a common colubrid snake that possesses a series of paired sac-like nuchal glands behind the head. When pressure is applied to the nuchal area, the thin skin over the nuchal glands can rupture and release secretions. In Japan, 19 cases of ophthalmia caused by the nuchal gland secretion of R. tigrinus have been reported. However, only one case has been documented in an English report. A 72-year old woman was sprayed by the nuchal gland fluid of R. tigrinus in her right eye. She presented with symptoms of eye pain and blurred vision. A slit-lamp examination revealed diffuse superficial keratitis, corneal stromal edema with Descemet membrane folds, and conjunctival injection. The best-corrected visual acuity (BCVA) of her right eye was 0.6. She was prescribed 0.5% moxifloxacin and 0.1% fluorometholone eye drops four times a day, and the symptoms resolved without sequelae within 5 days. The BCVA in the right eye improved to 1.0. In previous reports, ophthalmic examinations revealed conjunctivitis, keratitis, and corneal edema with Descemet membrane folds. Topical antibiotics and corticosteroid were prescribed in most cases, and eyes healed within 5-7 days without any sequelae. While corneal edema may resolve spontaneously in a few days when inhibition of the toxin has ceased, the use of topical steroids is recommended, as it can increase the activity of Na/K pumps that remained functional, thereby accelerating recovery. In fact, our patient used a topical steroid and recovered without sequelae.

OBJECTIVE: To explore the effects of cyclosporine A (CsA) in the management of atopic keratoconjunctivitis (AKC).
METHODS: Open single-group interventional consecutive cohort study (case series) at a single eye care facility in the UK. We reviewed the electronic patient records of 99 children and young people (CYP) aged 3.4-18 years with AKC treated with topical CsA 1 mg/ml. Main outcome measures were number of prescriptions and hospital clinic visits over 12 months before and after the start of CsA and the proportion of CYP affected by adverse effects.
RESULTS: The median number of inflammatory episodes requiring treatment with topical corticosteroids (tCS) fell from 3 (interquartile range IQR 1-4) during the 12 months prior to CsA to 1 (IQR 0-3) during the 12 months after, excluding tCS prescriptions with the first CsA prescription (Wilcoxon signed ranks test, 2 tailed, p < 0.01). In the 12-month period following initiation of CsA 1 mg/ml with concomitant prescription of tCS (n = 66), daily dosage of steroids was reduced in 62 CYP (93.9%), and they were discontinued in 43 (65.2%). The median number of hospital visits fell from 4 (IQR 3-6) to 3 (IQR 2-5; Wilcoxon p < 0.01). Adverse events leading to discontinuation of CsA were stinging (instillation site pain; 9/99, 9%) and a transient skin rash (1/99, 1%).
CONCLUSIONS: Off-label use of commercial preparations of CsA 1 mg/ml significantly reduces the need for concomitant topical corticosteroids and hospital clinic visits in CYP with AKC. Stinging and skin rash can lead to discontinuation.
