A method for teaching depth of corneal lesions using a portable slit lamp (biomicroscope).

A novel, simple, and inexpensive model for teaching depth of lesions within the cornea using slit lamp biomicroscopy to veterinary students, ophthalmology residents, and general clinicians with access to a slit lamp biomicroscope is described. Using common laboratory items, this method can be created in any clinic and can be used to teach and quiz students through independent study with objective self-testing achieved.

Protocolo Clínico e Diretrizes Terapêuticas da Degeneração Macular Relacionada à Idade (forma neovascular) / Clinical Protocol and Therapeutic Guidelines of macular degeneration related to age (neovascular form)

CONTEXTO: Os PCDT são documentos que visam garantir o melhor cuidado de saúde diante do contexto brasileiro e dos recursos disponíveis no SUS. Podem ser utilizados como materiais educativos aos profissionais de saúde, auxílio administrativo aos gestores, regulamentação da conduta assistencial perante o Poder Judiciário e explicitação de direitos aos usuários do SUS. Os PCDT são os documentos oficiais do SUS que estabelecem critérios para o diagnóstico de uma doença ou agravo à saúde; tratamento preconizado, com os medicamentos e demais produtos apropriados, quando couber; posologias recomendadas; mecanismos de controle clínico; e acompanhamento e verificação dos resultados terapêuticos a serem seguidos pelos gestores do SUS. Os PCDT devem incluir recomendações de condutas, medicamentos ou produtos para as diferentes fases evolutivas da doença ou do agravo à saúde de que se tratam, bem como aqueles indicados em casos de perda de eficácia e de surgimento de intolerância ou reação adversa relevante,

Renal cell carcinoma choroidal metastasis recorded by smartphone with interface eyepiece adapter mounted on slit lamp: A case report.

RATIONALE: Ocular metastasis of renal cell carcinoma (RCC) is rare, and mainly located on the choroid. We report a choroidal metastasis from RCC, which was recorded by a smartphone with an interface eyepiece adapter mounted on a slit lamp. PATIENT CONCERNS: A 45-year-old female presented with 1-month history of painless occlusion of the vision field on the left eye, who had undergone right nephrectomy for RCC 19 months ago. DIAGNOSES: A smooth, hemispherical and brown protrusion was found behind the pupil nasally. An enhanced computed tomography scan of the orbit showed a slightly high-density hemispherical nodule involving the nasal portions of the left eyeball, the enhancement of the lesion was obvious and homogeneous. A metastatic choroidal space-occupying lesion from RCC was highly suspected according to the clinical and radiological findings. INTERVENTIONS: The patient was advised to undergo further treatment, such as radiotherapy. OUTCOMES: The images of choroid metastasis were recorded by the smartphone with the interface eyepiece adapter mounted on the slit lamp handily. CONCLUSIONS: The smartphone with an interface eyepiece adapter mounted on the slit lamp can be widely used to record the precious images in the clinic in a timely manner.

Tolerance to Light of Patients Suffering From Infectious Keratitis.

PURPOSE: With very photophobic patients, the advantages of red or near infrared light to develop new ophthalmology imaging devices seem obvious: no or little glare, possibility of long signal integration, no phototoxicity, and lesser autofluorescence of ocular tissues. Nevertheless, in this range, the shortest possible wavelength facilitates signal detection. The aim of this study was, thus, to determine the maximal irradiance tolerated with 6 wavelengths: 2 red, 2 far red, and 1 near infrared lights to determine the shortest wavelength well tolerated by patients, in comparison with the standard cobalt blue light of ophthalmology slitlamp. METHODS: An interventional, monocentric, single-group assignment study was conducted on 30 eyes of 30 patients with infectious keratitis. Thanks to a customized machine, the photophobic eye was exposed to the 6 lights with increasing intensity. The patients switched off the light when the discomfort was too elevated. The maximal cumulative irradiance possible at 482, 650, 675, 700, 750, and 800 nm were 171, 689, 759, 862, 920, and 889 mW/cm, respectively. RESULTS: The maximal cumulative irradiance tolerated by patients increased significantly with wavelength (P < 0.001), but the difference was not significant between each increment: red at 675 nm gave a significantly higher cumulative irradiance than blue at 482 nm; red at 700 nm did not provide significant gain compared with 675 nm; and far red at 750 nm still provided additional gain compared with 700 nm, but no significant gain was observed between 750 and 800 nm. The shortest wavelengths were stopped more quickly, and more than 50% of patients reached the maximum irradiance delivered by the source at 750 and 800 nm. CONCLUSIONS: We demonstrate that a light source at 750 and 800 nm can be used for ophthalmic imaging with good tolerance in photophobic patients. CLINICAL TRIAL REGISTRATION: NCT03586505.
