This is a retrospective case report of a male patient referred to the PUC Campinas Hospital as a victim of blunt car trauma. On ophthalmological examination, the patient had bilateral retinal changes in the foveal region, causing low visual acuity in both eyes. Knowing that ocular trauma is the main cause of legal blindness in working-age people, this study aimed to highlight the importance of ophthalmological evaluation to provide the necessary treatment and follow-up to minimize the ocular sequelae resulting from trauma.

Retrobulbar hemorrhage (RBH) is an ophthalmological complication with the potential risk of irreversible blindness due to the compressive effect on the optic nerve. Cases of patients with a history of antiaggregation and/or anticoagulation therapy and RBH have been reported in the literature; ophthalmologists should keep this antecedent in mind and consider the risk–benefit of surgery while working in conjunction with the area of anesthesia to establish the times when medication is suspended or initiated. Similarly, early and timely identification of signs and symptoms related to this complication improves patients' visual prognosis. The following describes the case of a patient who had RBH associated with the use of antiplatelet therapy.

The utility of retropupillary (RP) iris-fixated lenses, even when the iris support is deemed inadequate is portrayed in this case series. The case series emphasizes iris-claw lens as an effective alternative in cases where there is a disfigurement of the iris with meticulous surgical skills. A 58-year-old with diminution of vision in the right eye for 6 months had a vision of 6/60, iris coloboma inferiorly with zonule loss and cataractous lens. Manual small-incision cataract surgery (M-SICS) was performed with placement of iris-claw lens despite the presence of iris disfiguration. A 62-year-old male with diminution of vision in the left eye had a vision of counting fingers at 1 m. On slit-lamp examination, iris atrophy, an oval-shaped pupil with a maximum of 5 mm eccentric dilation, cataractous lens inferiorly subluxated and partially absorbed, a breach in the anterior capsule, and vitreous strands were noted in the anterior chamber. M-SICS with iris-claw lens was then performed. A 3-year-old female child with a history of trauma to the left eye had a vision of perception of light only. On anterior segment evaluation, she had radial, full-thickness corneoscleral tear with iris plugging the wound, iris trauma, and traumatic immature cataract. Left eye corneal tear repair with cataract extraction and iris-claw insertion was performed. Postoperative vision on follow-up after a month was 6/12p in all three cases. Iris claw lens being readily available, and surgical technique of insertion being easy and quick, serves as one of the effective alternatives for the intraocular lens in difficult situations.

We report a rare case of ocular cryptococcosis that presents as chorioretinitis in a patient with acquired immunodeficiency syndrome.

Ocular surface complications secondary to continuous positive airway pressure (CPAP) machines have been previously reported such as ocular irritation, dry eye disease, lid laxity, and floppy eyelid syndrome. No severe ocular complications have been specified in the literature. We report a serious ocular complication in a patient under helmet CPAP (hCPAP). A 68-year-old male with COVID-19 pneumonia required ventilatory support with hCPAP. Following 5 days, the patient started complaining of ocular discomfort, purulent discharge in his left eye, and ocular dryness upon awakening. Ophthalmological examination showed no light perception in the left eye and slit-lamp biomicroscopy revealed atalamia, loss of corneal transparency with superior infiltrates, and a total epithelial defect with iris herniation and a central perforation. Considering the patient's progressive worsening clinical condition, with a painful blind eye, left evisceration was performed. It is important to be aware of possible ophthalmological complications related to ventilation since prompt diagnosis and treatment can avoid poor visual outcomes. In this clinical case, we faced a serious ocular complication following hCPAP ventilation.

Exotropia is a cosmetically distressing strabismus with lasting negative psychosocial impact on the patient. Aim: The purpose of our study was to apply the Classification of Eye Movement Abnormalities and Strabismus (CEMAS) to the patients of exotropia (XT) in our study, identify the common types and causes of this cosmetically and psychosocially distressing strabismus, and to determine if any of these causes are preventable. Materials and Methods: A prospective, cross-sectional study was carried out in patients aged 6 months and more with exotropia attending the ophthalmology outpatient department of a tertiary care hospital from December 2016 to July 2018. Complete strabismus evaluation of the patients was done, the exotropia seen in the patients was categorized in types according to the CEMAS classification and possible causes of exotropia were studied. Results: Of the total 120 patients, 110 had comitant XT, whereas 10 had incomitant. Of the 110 comitant cases, intermittent XT was maximum – 54 (45%). A significant number of patients had XT due to sensory or neurological causes 46 (38.8%). The etiology of XT due to sensory or neurological causes included amblyopia due to uncorrected refractive errors, trauma, media opacities in cornea and lens, and posterior segment diseases. Other causes included developmental delay, congenital fibrosis of the extraocular muscles, isolated 3^rd N palsy, and basic XT. Conclusions: Our study shows that although majority of the patients had intermittent exotropia, a significant number of patients had exotropia due to visual or neurological causes, which may be preventable in many cases. Diagnosis of the cause of XT at the appropriate time may prevent unnecessary visual loss and reduce the negative psychosocial impact of squint.
