ABSTRACT Juvenile glaucoma and retinoschisis are rare diseases alone. They occur bilaterally with early onset, resulting in severe visual loss. Juvenile glaucoma is mainly described in males, with high intraocular pressure, and juvenile retinoschisis is characterized by the formation of retinal cysts. This case reports a 16-year-old male patient with progressive visual loss that presents an association of both pathologies, which is an uncommon and severe involvement. After adequate diagnosis and drug treatment, the condition improved and did not require […]

ABSTRACT Chlorpromazine is a medication widely used in psychiatry for the treatment of psychoses, especially schizophrenia. Since 1964, published articles have been correlating this medication with the appearance of ocular alterations. In this paper, we report the case of a 65-year-old patient with ocular effects due to long-term therapy with chlorpromazine. Biomicroscopy of both eyes presented diffuse granular brown deposits, most prominent at the deep stroma and corneal endothelium level. Also showed anterior subcapsular brown deposits with a stellate pattern […]

ABSTRACT Hyperplastic primary vitreous persistence, currently referred to as fetal vasculature persistence, is a congenital anomaly that results from non-regression of the primary vascular vitreous and hyaloid artery system during embryogenesis. It is a unilateral anomaly in the vast majority of cases, sporadic and commonly not associated with any other systemic finding. Clinically, this condition can be classified into anterior and posterior persistence of fetal vasculature. The anterior condition is related to the ciliary artery system, while the persistence of […]

ABSTRACT Hydrocephalus is defined as ventricular dilation caused by increased intraventricular and intracranial pressure when untreated or due to treatment failure. Optical pathways can often cause optic atrophy due to the proximity to the lateral hazard when dilation occurs. Hydrocephalus can lead to optic atrophy, as well as other pathologies. Pituitary tumors share this same sign, in addition to causing bitemporal hemianopia when it compresses the optic chiasm. In addition, bitemporal hemianopia is the visual disturbance most commonly found in […]

ABSTRACT Pterygium is one of the diseases that most affect the ocular surface, especially in regions close to the equator. It mainly affects young adults and can cause symptoms, as well as aesthetic and optical impairment. We report a case of pterygium excision classified by grade II corneal extension and Tan grade 2 vascularization with previous laser in situ keratomileusis (LASIK) surgery, using a new technique, the Moscovici technique, which is based on dissection with an air bubble to separate […]

ABSTRACT Myelinated retinal nerve fibers are rare congenital anomalies that appear as gray-white patches. They may be present in a syndrome characterized by ipsilateral myelinated retinal nerve fibers, myopia and amblyopia. The author reported an ellipsoid zone defect on spectral domain optical coherence tomography in a case of Straatsma syndrome without macular extension.

ABSTRACT In the literature, there is a confusing classification among congenital floppy eyelid, eyelid eversion and ectropion. They are described as eyelid malposition with laxity and out-turning of the eyelids in newborns, usually associated with conjunctival prolapse and chemosis. Although the underlying pathophysiology of these rare conditions is obscure, they share anatomic characteristics. Thus, instead of a plethora of denominations, a spectrum approach should join these entities. In this paper, the authors present a case series of four patients that […]

ABSTRACT Choroid hemangioma is a benign, well-delimited orange-red, vascular tumor characterized by an elevated plaque. It is a rare tumor with a prevalence of one case in every 40 choroidal tumors. It can be diagnosed by the clinic associated with biomicroscopic evaluation and complementary tests to differentiate from other tumors. Treatment can be expectant in asymptomatic cases. For symptomatic cases or those with the presence of subretinal fluid, there are several therapies. The objective of this study was to report […]
