RESUMEN
A 54-year-old woman with cutaneous malignant melanoma developed Vogt-Kayanagi-Harada (VKH)-like uveitis induced by dabrafenib/trametinib therapy. Dabrafenib was discontinued but she continued to use trametinib due to the risk of disease progression. Intraocular inflammation resolved after cessation of dabrafenib and administration of topical and systemic corticosteroids. Our patient outlines the importance of recognizing VKH-like uveitis as a consequence of dabrafenib/trametinib therapy in melanoma patients and highlights a question about the potential role of each drug in developing uveitis.

PURPOSE: Ocular burns are ophthalmic emergencies that can cause devastating injuries. This study aimed to analyze the epidemiology, complications, and management of ocular-periocular burns. METHODS: A total of 193 patients with ocular-periocular burns were admitted to our tertiary hospital from January 2018 to December 2020. The demographic characteristics of the patients, injury variables, complications, and treatments were evaluated. RESULTS: There were 142 male (73.6%) and 51 female (26.4%) patients with a mean age of 32.53±17.75 years. The average total body surface area was 12% (range, 1-80%). Injuries were most common at work (52.3%) and home (36.3%). Thermal burns were the most common injuries (74.6%), followed by chemical (14.5%) and electrical burns (10.9%). Alkaline agents (75.0%), mainly sodium hydroxide and lime, were common in chemical burns. Superficial lid burns were significantly higher in the thermal group (p < 0.001), and grade III-IV corneal burns were significantly higher in the chemical group (p < 0.001). Various complications were developed in 50 (13%) eyes. Medical treatment only was performed in 318 (82.4%) eyes, and additional surgical treatment was performed in 64 (17.6%) eyes; however, 54 (14.0%) underwent more than one surgery. The most common complications were corneal scars (7.3%), limbal deficiency (4.1%), and ectropion (3.9%). The most frequent procedures performed were amniotic membrane transplantation (AMT) (11.9%) and tarsorrhaphy (6.7%). CONCLUSION: Chemical burns, limbal and conjunctival ischemia, and full-thickness eyelid defects had a poor prognosis. The degree of limbal deficiency and injury of intraocular structures were found to have a great influence on the outcome of their visual acuity.

PURPOSE: To investigate whether peripapillary retinal nerve fiber layer (pRNFL) and macular ganglion cell-inner plexiform layer (GCIPL) thinning are present in patients with unilateral hypertensive Cytomegalovirus anterior uveitis (hCMV AU). METHODS: We included 19 eyes with unilateral hCMV AU and their unaffected fellow eyes as the control group in this study. Peripapillary RNFL and macular GCIPL changes were determined using spectral-domain (SD) - optical coherence tomography (OCT). RESULTS: The overall calculated mean pRNFL thickness was significantly lower in the effected eyes with hCMV AU than in the uneffected fellow eyes (p = 0.012). The mean macular GCIPL thickness in the affected eyes was also significantly lower than in the normal eyes (p < 0.001). CONCLUSION: Measurement of pRNFL and macular GCIPL thickness with OCT may detect signs of damage before the visual field changes in patients with hypertensive CMV AU. Early aggressive treatment in these patients may prevent further glaucomatous damage.

To investigate cord arterial blood sample and the relationship between birth stress and intraocular pressure in infants at 5 min after delivery. The IOP measurements were taken using Tonopen-Avia tonometer to 158 newborns (158 eyes) at 5th min after birth, in a university hospital. Cord blood was collected within 3 min after delivery. Intraocular pressure, gender, gestation period, mode of delivery, and birth weight of newborns were noted from medical records. Sixty-two babies were delivered by normal vaginal delivery (NVD) and 96 by cesarian section (C/S). Mean IOP of NVD and C/S groups were 19.56 ± 3.84 and 17.42 ± 3.50, respectively. There was significant difference of mean IOP between two groups. (p < 0.001) There were significant differences between two groups regarding APGAR score (p < 0.001) and cord blood adrenaline (p = 0.003), noradrenaline (p = 0.008), and cortisol (p < 0.001) levels. There was no difference between infant corneal thickness measurements (p = 0.698). In correlation analyses, there is a strong negative correlation between the labor type and postpartum measurements except corneal thickness. Correlation analyses of the 5th min intraocular pressure of the groups individually revealed significant correlation in the NVD group. The conclusion is that the intraocular pressure of newborn infants was higher in NVD delivery compare to C/S. Blood hormonal changes in different anesthesia types and physical stress was thought as the main reason of this result.

We report a case of group G Streptococcus endophthalmitis following an intravitreal ranibizumab injection for a choroidal neovascular membrane. Pars plana vitrectomy was applied for endophthalmitis and group G Streptococcus cultures were isolated in the vitreous samples taken from the patient. Twenty-four hours following pars plana vitrectomy the patient underwent myocardial infarction and cardiac arrest. To our knowledge this is the first reported case of group G Streptococcus endophthalmitis following an intravitreal injection.
