RESUMO
Dry eye disease (DED) is a multifactorial disorder representing one of the most common ocular morbidities and a significant public health problem. It often results in eye discomfort, visual disturbances and potential damage to the corneal surface affecting quality of life (QOL). In recent years, the relationship between DED and psychiatric disorders has been gaining attention. A number of epidemiological studies have reported a possible association between dry eye and psychiatric disorders showing that the subjective symptoms of dry eye can be affected not only by changes of the tear film and ocular surface but also psychological factors such as anxiety, depression, schizophrenia, post-traumatic stress disorder (PTSP) and subjective happiness. Apart from psychiatric disorders, psychiatric medications are also considered as risk factors for DED due to their influence on the tear film status. The incidence of ocular side effects increases rapidly with the use of polypharmacy, a very common form of treatment used in psychiatry. There is often inconsistency between signs and symptoms of DED, where symptoms often are more related to non-ocular conditions including psychiatric disorders than to tear film parameters. Consequently, in many cases DED may be considered as a psychiatric as well as ophthalmological problem. Psychiatrists and ophthalmologists need to be aware of the potential influence of psychiatric disorders and medications on tear film stability. In treatment of psychiatric patients, an integrative and transdisciplinary approach will result in better functioning and higher QOL.

BACKGROUND: Neurofibromatosis type 1 (NF1) is an autosomal dominant a multisystem genetic disorder that primarily involves the skin and the nervous system. The incidence of the disease is 1:3000-4000 live-born children, equally in both sexes. The diagnosis of NF1 is determined individually with any two of the following clinical features: café-au-lait spots, intertriginous freckling, Lisch nodules, neurofibromas, optic glioma, distinctive bone lesions and first-degree family relative with NF1. NF1 is a disease most commonly diagnosed and treated by neuropediatricians. RESULTS: Cognitive and behavioral disorders affect between 50-80% of all children with NF1. Children with NF1 show impairments in attention, visual perception, language, executive function, academic skills, and behavior. This requires a multidisciplinary approach to the treatment s as seen in the case we present. Furthermore, NF1 is often associated with psychiatric disorders, which are more frequent in this disease than in general population, according to some studies even up to 33% patients. Psychiatric disorders are more frequent in NF1 than in the general population, particularly in children. They include dysthymia, depressive mood, anxiety, and personality disorders. Bipolar mood disorders or schizophrenia are rather rare. The majority of studies have focused on physical health and neurocognitive function in NF1, whereas psychiatric disorders associated with this disease remain unclear and poorly documented. CONCLUSIONS: We present a case of an eight-year-old boy with behavioural and learning disabilities referred for psychological and psychiatric evaluation as well as an overview of NF-related psychiatric illnesses described in the literature.

Traumatic optic neuropathy (TON) is a serious vision threatening condition that can be caused by ocular or head trauma. Indirect damage to the optic nerve is the most common form of TON occurring in 0.5% to 5% of all closed head trauma cases. Although the degree of visual loss after indirect TON may vary, approximately 50% of all patients are left with 'light perception' or 'no light perception' vision, making TON a significant cause of permanent vision loss. We present a 47-year-old male patient with a history of right eye keratoconus following a motorcycle crash. Visual acuity was of 'counting fingers at 2 meters' on the right eye due to keratoconus and 'counting fingers at 1 meter' on the left eye as a consequence of trauma. The Octopus visual field showed diffuse re-duction in retinal sensitivity and the Ishihara color test indicated dysfunction of color perception on the left eye. Relative afferent pupillary defect was also present. Computed tomography revealed multifragmentary fracture of the frontal sinus and the roof of the left orbit without bone displacement. Based on the findings, conservative corticosteroid therapy without surgery was conducted. The patient responded well to treatment with complete ophthalmologic recovery.

Conjunctival melanoma is a rare but sight and life threatening malignancy. It accounts for 2%-5% of all ocular tumours and 5%-7% of all ocular melanomas with an incidence of 0.2-0.8 per million in the Caucasian population with rare cases reported in the non-Caucasians. In recent decades the incidence of uveal melanoma has been relatively stable whilst conjunctival and cutaneous melanoma have shown increasing incidence which may be connected to the result of environmental exposure to ultraviolet light. The dissimilarity in incidence between light and dark pigmented individuals observed in conjunctival melanomas compared to uveal and cutaneous melanomas may be related to differences in their histological structures and genetic profile. Recent molecular biological studies support the fact that each type of melanoma undergoes its own molecular changes and has characteristic biological behaviour. Further studies are required for each type of melanoma in order to ascertain their individual etiology and pathogenesis and based on this knowledge develop relevant preventative and treatment procedures.
